Supply chain management: a profile of micro enterprises.
Pearson, Terry R. ; Parmenter, David A.
ABSTRACT
Micro enterprises (firms with less than nine employees) represent
an increasingly important component of the economy. The United States literature typically defines small businesses as having less than 500
employees, incorporating micro firms into this broader definition.
Although there has been a diversity of studies focusing on small and
medium sized enterprise supply chain management, there has been
insufficient research on micro entities. Thus, little is known about
supply chain management in micro ventures. This study develops a profile
of micro enterprise supply chain management practices, the factors that
encourage or discourage the implementation of supply chain management
activities, and the impact of these supply chain activities on firm
performance. The findings of this study indicate that micro enterprises
tend to implement supply chain management methods and supply chain
management appears to increase micro firm performance.
INTRODUCTION
For the last decade many large enterprises (LEs), and to a lesser
extent small to medium sized enterprises (SMEs), have placed increasing
emphasis on the implementation of supply chain management (Chopra &
Meindle, 2001; Mentzer, 2000). Supply chain management (SCM) is a
philosophy and a set of business practices that allow firms to more
closely coordinate their activities with suppliers, distributors,
retailers and consumers (Laudon & Laudon, 2001; Simchi-Levi,
Kaminsky & Simchi-Levi, 2003). The SCM literature is somewhat
inconsistent in its definition of SMEs, but tends to utilize size as the
focal point, with LEs characterized as 500 or more employees and SMEs as
less than 500 employees, although in some cases no definition is offered
at all (Barringer, 1997; Brush, 2001; Committee on Supply Chain
Integration, 2000; Larson, 2005). In addition to the number of
employees, small firms are also delineated by such factors as finances,
sector and ownership, effectuating a universal definition problematic
(Curran & Blackburn, 2001; Storey, 1994). Micro enterprises, the
focus of this study, are a subset of SMEs, with micro entities defined
as those having nine or fewer employees (European Commission, 1996;
Fulantelli, Allegra & Vitrano, A.Z.P., 2002). SMEs by definition
include micro firms, SMEs can also be referred to as micro, small and
medium sized enterprises or MSMEs. Although the literature includes
studies of supply chain management in SME's, it does not to date
appear to address SCM implementation by micro organizations in
particular.
The growth of small business and its impact on the economy and
employment has been recognized by both the public and private sectors as
well as by academics (Chapman, Ettkin & Helms, 2000; Committee on
Supply Chain Integration, 2000; Curran & Blackburn, 2001; Park &
Krishnan, 2001; Schwenk & Shrader, 1993; Watkins, 1993).
Furthermore, SMEs have become increasingly more important to the United
States economy in the 1990's as more employees at LEs have been
downsized and the growing attention to core competencies among many
companies has evolved to increased outsourcing by LEs to smaller
suppliers (Park & Krishman, 2001). SMEs not only comprise the
majority of the United States manufacturing facilities and employees,
but account for much of the innovation (Committee on Supply Chain
Integration, 2000).
SCM has taken on critical importance within the context of small
business due to its impact on long-term performance, competitive
advantage, strategic competence and competitiveness (Cavinato, 1992;
Park & Krishnan, 2001). Small businesses are already involved in
SCM, whether the owner-managers of those small businesses recognize it
or not (Chapman et al. 2000). Successful implementation of SCM can
reduce costs, increase revenues, enhance productivity and quality,
advance technological innovation and in general allow an organization to
be more competitive (Chase, Aquilano & Jacobs, 2000; Christopher,
2000; Fisher, 1997; Gryna, 2001; Hult, Thomas, Nichols & Giunipero
2000; Mainardi, Salva & Sanderson, 1999; Spekman, Kamauff, &
Salmond, 1994). MSMEs cannot dismiss SCM and hope to remain competitive
in the future (Committee on Supply Chain Integration, 2000; Lummus &
Vakurka, 1999).
The goal of this research is to develop information that will
assist in answering the inquiry, is SCM implementation related to firm
size and performance (Kaufman, Wood & Theyel, 2000; Magretta, 1998;
Notman, 1998; Quayle, 2002; Tulip, 2000). The previous literature has
converged on LE supply chain management and somewhat less on SME's.
The research agenda of this study will provide a first glimpse of the
impact that small size (micro enterprises) might have on both the
implementation of supply chain activities and the benefits that result
from these activities. The study employs a self reporting survey that
addresses the following five issues: the extent to which micro
enterprises have implemented SCM, the determinants that encourage SCM
implementation among micro firms, the factors that discourage SCM
implementation, the impact of SCM on micro firm performance, and the
methods of SCM that micro organizations would like to receive additional
training.
LITERATURE REVIEW
Supply chain management has evolved from two main perspectives, the
upstream-focused procurement orientation of the manufacturer and
supplier and the downstream-focused transportation and logistics
orientation of the distributor and retailer (Mentzer et al., 2001; Tan,
2001). SCM is a fairly recent concept and although numerous models have
been proposed no standardized definition has emerged to date (Gibson,
Mentzer & Cook, 2005; Quayle, 2002; Tan, 2001). The various supply
chain paradigms can encompass elements that range from the comparatively
narrow to the very broad. Gibson, Mentzer and Cook (2005) develop a
confined definition of SCM that emphasizes the importance of
collaboration as well as alignment with the organization's
strategy. In contrast, the Supply Chain Operations Reference Model
(SCOR) takes a more extensive approach which spans the entire supply
chain from the supplier's supplier to the customer's customer,
but does omit certain activities such as product design, quality,
information technology and elements of service after the sale (Schultz,
2003; Supply Chain Council, 2005). The Council of Supply Chain
Management Professionals defines SCM more expansively in its Supply
Chain Management Process Standards (2004 abcdef), including all of the
activities involved in planning for SCM, sourcing the required inputs,
manufacturing the product, delivering the product and processing
returns, as well as incorporating supply chain facilitators such as
quality, information technology and security.
Although there are examples of supply chain failures, many LEs have
achieved significant success through the implementation of SCM (Chapman
et al., 2000). Kopezak and Johnson (2003) observed that supply chain
management's ability to leverage the skills and resources of
partner entities allows for increased differentiation that can develop
customer loyalty. Furthermore, SCM is being encouraged by such issues as
global competition, outsourcing, cost reduction requirements,
e-commerce, and decreased product life cycles (Ericksen, Suri,
El-Jawhari & Armstrong, 2005). These factors maturate to extended
supply lines, new members in the supply chain and longer as well as more
complex distribution channels that must be coordinated The knowledge of
the abilities of each partner in the chain joined with an increased
comprehension of the end users' needs allows businesses to add
services and features which create value beyond the cost to the chain
members (Brewer & Speh, 2000). The chain's sharing of both
demand and supply related information enables more effective planning
which results in better utilization of assets, lower inventory, reduced
costs and improved customer service.
In theory, smaller firms may have some characteristics that prove
advantageous when implementing supply chain management. MSMEs tend to be
less bureaucratic, more agile and more entrepreneurially oriented.
Despite these potential advantages MSME's have some limitations due
to their small size that may inhibit their implementation of SCM,
notably a lack of resources (Hvolby, Trienekens & Carrie, 2001).
Moreover, controversy concerning how SCM affects SMEs exists, especially
with respect to findings that suggest SCM is negatively related to SME performance. A study conducted by Arend and Wisner (2005) was
particularly discouraging. Arend and Wisner (2205) demonstrated that
successful SMEs were more likely to employ SCM methods than less
successful organizations but that, surprisingly, supply chain
utilization tended to harm these more successful firms. Several
alternative explanations are proposed by the authors for this finding
including the proposition that SMEs did not select partners based on
strategic alignment but rather on ease of integration. For example,
partners might be selected on the criteria of compatible computer
systems.
SMEs implement SCM differently than LEs and may not be qualified to
utilize SCM as effectively (Gammelguard & Larson, 2001). SMEs could
have been bullied into SCM by a larger and more powerful supply chain
partner (Maloni & Benton, 2000), with this tendency toward bullying increasing as competitive pressures on LE's intensify (Maloni &
Benton, 2000). Simatupang and Sridharan (2004) noted the importance of
having an incentive system designed to encourage SMEs to perform in an
effective and efficient manner in the roles assigned to them by the
supply chain. Arend and Wismer (2005) suggest that SMEs might have
difficulty executing SCM as an important component of their strategy,
the choice of supply chain partners could impede or propel SCM and some
firms may employ SCM only when it is easy to do so.
Songini (2001) reported that numerous LEs were frustrated by the
lack of information technology expertise demonstrated by many of their
smaller suppliers. Quayle (2002) noted that many LEs were developing
strategies to leverage their skills in order to align this skill set
with the suppliers, but these strategies were undermined by the smaller
suppliers' inability or unwillingness to fully integrate with the
LEs. Quayle's (2002) research discovered that SMEs resisted SCM for
numerous reasons: the inability to overcome traditional practices, a
lack of knowledge concerning SCM, insufficient management time,
inadequate capital, deficient resources and the incapacity to proceed
without external support. Larson, Carr and Dhariwai (2005) discovered
manufacturers communicate less frequently with small suppliers compared
to large suppliers and manufacturers believe small companies obstruct
supply chain implementation more than large suppliers. Therefore, the
internet may not be the great leveling agent it has been professed to be
(Larson, 2005). Additionally, small firms tend to be more risk-averse
and more concerned with survival (Pollard & Hayne, 1998). SCM
reluctance might also be attributable to the role that managers play in
smaller entities. Typically managers in smaller businesses are required
to be involved in the day-to-day and hour-to-hour operations of the
organization and have less time to develop the strategy necessary to
guide supply chain implementation. Smaller companies with limited
resources and skills may simply elect not to implement closer ties with
suppliers and customers for numerous reasons, including a loss of
freedom and sense of individuality, the required cooperation with other
supply chain members, and difficulty integrating information technology
(Gales & Blackburn, 1990; Fulantelli et al., 2002; Hvolby et al.,
2001; Lyons & Bailey, 1993; Spekman, 1988). Although the concerns
raised are not unreasonable, SCM's potential ability to provide
more benefits than the traditional model of arms-length supplier
relationships demands that SMEs form closer and more collaborative
relationships with a reduced set of channel members to achieve this goal
(Anderson & Narus, 1990; Dwyer, Schurr & Oh, 1987; Helper,
1991).
The conclusion proposed after evaluating the literature is the
growing need for supply chain management practices among SMEs in this
customer-driven marketplace. Failure to implement SCM could ultimately
result in the loss of customers, something that should be of great
concern to SMEs. However, the cost and complexity of implementation, as
well as concerns about ROI and closer-than-usual collaboration with
other firms still impedes the progress among SMEs. The experience of
large enterprises has demonstrated the benefits that can be obtained
through SCM and has revealed some of the difficulties of implementation
as well.
The reality of the supply chain management literature is that it
does not address micro enterprises. Although research studies of SMEs
would likely include some micro firms among the sample, these studies do
not segregate micros as a separate category and thus provide no
conclusions pertaining specifically to micro entities. This research
study attempts to develop a supply chain management profile of micro
enterprises. The authors hypothesize that many micro firms are indeed
utilizing supply chain methods, although they may be doing so primarily
due to pressure from larger customers and suppliers.
METHODOLOGY
The Survey Questionnaire
The intent of this study is to answer five major research questions.
Which supply chain activities, if any, have been implemented by
micro firms?
What benefits, if any, have micro firms gained from their supply
chain activities?
What factors have encouraged micro firms to implement supply
chain activities?
What factors have discouraged greater implementation of supply
chain activities?
About which supply chain methods would micro enterprises most
like to learn more?
A survey questionnaire was designed to capture the data necessary
to answer these five questions. The survey includes questions as well as
a series of statements to which respondents can reply with "Agree
Strongly," "Agree," "Neutral,"
"Disagree" and "Disagree Strongly." These questions
and statements were carefully developed based on a rigorous review of
both the entrepreneurial and supply chain management literature. The
questionnaire was reviewed by colleagues with the relevant expertise and
revised repeatedly prior to being utilized.
The questionnaire contains eight sections. After the initial
section which solicits basic background information about each
responding firm, including the number of employees, the remaining
sections provide the SCM information that is central to this research.
Section 2 focuses on the environment in which the firm operates.
The purpose of this section is to estimate the extent to which a
firm's environment might encourage the implementation of SCM
practices. For example, a firm with particularly demanding customers
might be more motivated than the average firm to pursue various SCM
activities in order to improve its ability to meet those stringent
customer demands. Similarly, a firm competing in a commodity market may
have greater incentive to implement supply chain methods, either for the
cost-reduction benefits that would allow it to compete more effectively
on the basis of price or for the potential service-related benefits that
might allow its product to avoid commodity status. The section contains
seven statements, each of which calls for a response of "Agree
Strongly," "Agree," "Neutral,"
"Disagree," or "Disagree Strongly" (as do the
statements in Sections 3, 4 and 5 of the questionnaire). The seven
environment-related statements capture the degree to which:
Inputs and outputs are tangible goods rather than services
Demand varies dramatically and unpredictably
Customers are demanding and difficult to serve
Sub-par supplier performance would seriously hurt the firm's
performance
The firm's products or services qualify as commodities
Global sourcing and/or distribution is utilized
Sales are made to end users rather than to other organizations
Section 3 concentrates on the nature of the entity's leaders,
with the underlying assumption that the decision to implement SCM is
partially driven by the characteristics of the decision maker and not
just by the position and strategy of the organization, as suggested by
Park and Krishnan (2001). For instance, a leader with more formal
education would be more likely to be familiar with SCM and therefore
more inclined to seriously consider its use. A leader possessing
significant computer expertise would generally be less likely to resist
SCM solely because of its call for an increased utilization of
information technology. The four leadership-related statements in this
section develop the scope to which the firm's leadership:
Has received a significant amount of formal education
Is proactive rather than reactive
Embraces rather than resists change
Is proficient with information technology and can recognize
its benefits
Section 4, the centerpiece of the survey, converges on the
firm's implementation of various supply chain management
activities. The fourteen statements in this section are organized into
three categories--the firm's readiness or preparation for SCM
(three statements), the enterprise's implementation of various
supplier-oriented supply chain activities (seven statements) and the
entity's execution of diverse customer-oriented supply chain
activities (four statements). The fourteen questions in this section
attempt to discover the extent to which the firm:
Has a well-defined strategy and knows what its suppliers must do to
support that strategy
Possesses the necessary information and telecommunication technology
Has rationalized its internal processes
Works regularly with key suppliers to jointly solve problems
Works with key suppliers to jointly plan future activities
Shares demand-related information with suppliers
Reduces its supply base, retaining the best suppliers
Places serious effort into building trust and commitment with
key suppliers
Utilizes the internet to place most supplier orders
Has improved its processes and technology to enhance coordination
Works regularly with key customers to jointly solve problems
Works regularly with key customers to jointly plan future activities
Has customers willing to share demand-related information with
the firm
Has customers that utilize the internet to place orders with the
firm
Section 5 solicits opinions concerning the degree to which supply
chain activities have allowed the firm to achieve each of the five
benefits of reduced costs, improved service, impressive growth,
increased profits and enhanced trust and collaboration with suppliers
and/or customers. Although many of the benefits referenced in this
section would seem to call for the use of quantitative measures, the
authors chose to rely on opinions rather than more objective results due
to the fact that it is often extremely difficult to quantify the impact
of specific supply chain activities. LEs with complex accounting systems
may have difficulty in accurately determining the precise benefits of
individual SCM initiatives. This determination of benefits could be
expected to be even more problematic for smaller less formally managed
firms. As with sections 2 through 4, this section employees statements
calling for responses of "Agree Strongly," "Agree,"
and so on.
Section 6 requests the respondents to specify the factor or factors
that encouraged the firm to initiate SMC. A list of potential factors
was provided, with the list including "Other" as an option. It
is expected that a large percentage of the micro enterprises that have
implemented SCM will have accomplished this task due to pressure from
other firms, particularly pressure from important customers. Similarly,
Section 7 requests the respondents to specify the determinant or
determinants that discouraged the entity from executing supply chain
management to a greater extent than it has already accomplished.
Assorted weaknesses tied to the micro businesses' small size, such
as a lack of capital or technical expertise, are expected to be reported as common impediments to the utilization of supply chain management.
The final section, Section 8, inquires the sample to provide
information concerning the supply chain methods about which the firms
would like to learn more. This survey is being conducted with the
assistance of the local Small Business Development Center and therefore
one of its goals is to determine the education and counseling needs of
area micro enterprises. Many studies (Committee on Supply Chain
Integration, 2000; Gammelgaard & Larson, 2001; Quayle, 2002;
Songini, 2001) have noted the need for increased supply chain knowledge
among smaller firms, knowledge that can be used to the advantage of the
small firms themselves as well as for the benefit of their supply chain
partners. This need for increased supply chain expertise is expected to
be particularly critical for micro entities.
THE SAMPLE
The data for this study was collected utilizing a survey conducted
in the Texas Panhandle with the assistance of the Small Business
Development Center (SBDC). Although the study concentrates its primary
attention on micro enterprise supply chain practices it was decided to
include small firms (10-49 employees) in the sample in order to enable
comparisons between the two sizes of organizations. The survey mailing
list was developed systematically from an SBDC roster of over 9000 small
and micro firms in the region, a region that is largely rural with one
SMA of approximately 180,000 people. A mailing list of 480 firms was
selected, with micro firms making up approximately two thirds of the
list. In an attempt to increase the response rate, graduate students
contacted many of the selected firms prior to the mailing in order to
determine the appropriate employees at each business to whom the survey
should be forwarded. Generally an employee was selected based on
involvement with functions such as procurement, inventory management or
distribution. A total of 88 responses were received. After removing the
surveys with excessive missing data and those that were submitted by
organizations employing more than 49 employees, the usable sample
contained 43 micro firms and 30 small firms, an overall response rate of
approximately 14%. Roughly 75% of the micro firms in the sample
classified themselves as either service firms or retailers, with the
remainder of the sample categorized as raw material producers,
manufacturers or wholesalers/distributors. Service firms comprised the
greatest percentage of the small firm sample.
RESULTS
Micro Firm Utilization of Supply Chain Methods
The primary goal of this study is to determine the extent to which
micro enterprises are utilizing supply chain methods. As discussed
earlier in the paper, the authors hypothesize that micro firms are
performing supply chain activities, despite the lack of evidence
provided in the literature. The statements concerning micro firm
utilization of supply chain activities were presented in Section 4 of
the questionnaire and, as discussed earlier, allowed respondents to
select from "Agree Strongly," "Agree,"
"Neutral," "Disagree" and "Disagree
Strongly." These five possible responses were coded using the
integer values one through five, with one being assigned to "Agree
Strongly." Therefore, values of one or two signify a
respondent's agreement with a statement that a firm is employing a
particular supply chain method while values of three or larger signify a
lack of agreement.
The hypothesis test to evaluate if micro enterprises are performing
a particular supply chain activity takes the form of Ho: [micro]
[greater than or equal to] 3 versus Ha: [micro] < 3, with a lower
tail test being appropriate because of the coding scheme using smaller
values to signify agreement. A series of fourteen identical hypothesis
tests were performed for the statements in Section 4. The results are
illustrated in Table 1. All three of the supply chain readiness
statements achieved significance, as did three of the supplier-related
statements and one of the customer-related statements. Two more of the
supplier-related statements and one of the customer-related statements
achieved sample means of less than 3.0, but not sufficiently less to
achieve statistical significance. Only four statements resulted in
sample means of 3.0 or larger. These results provide convincing evidence
that supply chain methods are widely employed among even the smallest
firms. The activity of building relationships with suppliers received
the strongest support, with a sample mean of less than 2.0. This is not
surprising given the emphasis on closer supplier relationships depicted
not only throughout the supply chain literature but also in the earlier
literature concerning just-in-time manufacturing.
Pearson Correlation Coefficients were developed for the
environment-related characteristics from Section 2 and the
leadership-related attributes from Section 3 with the fourteen supply
chain activities listed above. Although a few significant correlations
were discovered between pairs of environment-related statements and
supply chain statements, there was no one environmental characteristic
that demonstrated a consistent pattern of relationships with the supply
chain methods. The leadership attributes demonstrated only a few
significant correlations. However, having a leader who is proficient with technology was significantly correlated with three supply chain
activities: employing the internet to place supplier purchase orders,
rationalizing linkages with suppliers and sharing information with
customers.
Benefits of Supply Chain Methods
Based on the research findings that micro firms are utilizing
supply chain methods, the obvious next step is to determine whether or
not these methods are providing tangible benefits. This analysis applies
the same lower-tailed testing format discussed above to the five
benefit-related statements in Section 5. Significant results were
achieved for three of the benefits, improved service, increased profits
and enhanced trust and collaboration with suppliers and/or customers.
These three benefits achieved sample means of 2.51, 2.71 and 2.40,
respectively. The remaining two benefits, reduced costs and impressive
growth, achieved sample means of less than 3.0, but the means were not
sufficiently less to be statistically significant.
Although it is not the purpose of this paper to discuss at length
the potential cause-and-effect relationships between individual supply
chain methods and firm performance, Pearson Correlation Coefficients
calculated for each pair of statements can provide some cursory insights. The correlations suggest the importance of a firm preparing to
take advantage of supply chain practices and methods. All three of the
preparation-related statements were significantly correlated with most
if not all of the five benefits. Having a well-defined strategy was
significantly correlated with all five benefits, with values ranging
from .327 to .505. Rationalizing internal processes was highly
correlated with all five benefits, with coefficients varying from .459
to .531. Possessing the necessary information and telecommunications
technology was significantly correlated with all of the benefits except
for collaboration with suppliers.
Of the supplier-related supply chain activities, rationalizing
links with suppliers was the most highly correlated and significantly
related to all five benefits with coefficients ranging from .425 to
.536. Using the internet to purchase from suppliers was significantly
correlated with reduced costs, impressive growth and increased profits.
Interestingly, the sample mean of 3.70 for employing the internet
suggests that most firms do not use the internet to place purchase
orders with suppliers. The correlations discussed here, however, suggest
that micro organizations that do exploit the internet may be deriving
substantial benefits from this activity. Various other supplier-related
activities achieved significance with one and sometimes two of the five
benefits.
Significant correlations were also identified among the
customer-related activities. Joint problem-solving with customers and
joint planning with customers were significantly related to all five
benefits, with correlations varying from .306 to .573. Sharing
information with customers was significantly related to four of the
benefits and using the internet to obtain a customer order was
significantly correlated to three of the benefits.
Factors Encouraging or Discouraging Supply Chain Implementation
Sections 6 and 7 of the questionnaire inquired respondents to
specify the issues that encouraged the use of supply chain management
and the factors that had discouraged them from implementing supply chain
management to a greater extent than they had so far accomplished. The
most commonly cited responses for supporting factors were the
firm's recognition of the potential benefits of supply chain
management (cited by 15 firms), pressure from suppliers and/or customers
(8), the necessary technology becoming available at a reasonable cost
(8), the need to match a competitor's supply chain competitive
advantage (6) and the necessary skills becoming available (4). These
results are quite hopeful for the future of supply chain utilization
among micro firms, suggesting that any micro hesitancy to adopt supply
chain management may be due more to a lack of resources and skills than
to an ignorance of supply chain management and its potential benefits.
The most commonly cited element discouraging greater execution of
supply chain methods was the belief that the firm was small enough to
operate effectively without formal processes and procedures (cited by 25
firms). While this claim may indeed be valid for some micro enterprises
given that inter-functional integration is not as problematic for an
organization with fewer employees and employees wear "many
hats," it is nevertheless a somewhat disappointing result in that
it conjures up a vision of the stereotypical entrepreneurial discomfort
with formal command and control structures. This mindset may prevent the
leadership at some micro businesses from recognizing the need for supply
chain management until that need has become critical. The other most
commonly cited determinants discouraging greater implementation were the
requirements of time and money (10), the belief that supply chain
activities would provide little benefit (8), and the unwillingness to
share sensitive information with other organizations (8).
Supply Chain Learning Requirements
In the final section of the questionnaire the respondents were
requested to specify the supply chain skills that they wished to further
develop. The results (from a sample size of 43) can be seen in Table 2.
Given the earlier findings of low levels of internet usage for
accepting customer orders and for placing orders with suppliers, it
would seem logical that many firms would be interested in learning more
about how to develop the internet to its fullest potential. It is
somewhat surprising to the authors that some of the more
technology-oriented options such as integrating the firm's computer
system with the customers' and suppliers' computer systems,
utilizing supply chain software, and technical issues such as RFID and
bar coding were not selected by more firms. It might be the case that
micro businesses are simply not sufficiently sophisticated yet to even
consider the need for these types of skills.
Micro Enterprises Versus Small Firms
The supply chain literature strongly suggests that large firms are
more likely to adopt supply chain methods. In this research study the
authors determined that micro firms had substantially progressed towards
supply chain management implementation. With data available from the
research study for both micro businesses (0 to 9 employees) and small
firms (10 to 49 employees), it makes sense to contrast the two types in
terms of their utilization of supply chain activities.
The appropriate hypothesis test to evaluate whether small firms are
making greater application of a particular supply chain method is a
two-independent-sample t test utilizing the hypotheses Ho:
[[micro].sub.micro] - [[micro].sub.small] [less than or equal to] 0
versus Ha: [[micro].sub.micro] - [[micro].sub.small] > 0. An upper
tail test is appropriate because small firms should consistently receive
lower scores (noting that "Strongly Agree" was coded as 1) if
they are making greater use of the supply chain methods. A series of
fourteen identical hypothesis tests were performed for the statements in
Section 4. The results demonstrated little statistical significance,
with the null hypothesis being rejected for only one activity,
rationalizing internal processes. However, the sample mean for the small
firms was less than that of the micro enterprises for all but two of the
activities. Thus, a consistent pattern that suggests increased use of
supply chain methods by small firms despite the fact that the observed
differences were too small to achieve statistical significance.
This research study demonstrates, rather surprisingly given the
lack of evidence in the literature, that micro organizations are
adopting supply chain methods extensively. The contrast of micro
enterprises with small firms, however, implies that micro organizations
are, as expected, performing supply chain activities somewhat less
extensively than small firms.
DISCUSSION
When beginning this study the authors fully expected to discover
that micro enterprises were utilizing various supply chain methods
despite the lack of evidence in the literature. It was surprising,
however, to discover the extent to which micro firms claim to be
employing supply chain methods. This higher-than-expected level of
supply chain achievement is a hopeful sign, not only for the future
success of the micro organizations applying these practices and methods,
but for the future success of their suppliers and customers.
Hopeful is also the feeling engendered by the micro firm responses
to the question concerning factors encouraging supply chain
implementation. It was expected that most of the micro entities that had
accomplished supply chain methods would have incorporated these methods
primarily due to pressure from important customers or suppliers. The
results, however, suggest that many micro businesses are fully aware of
the potential benefits of supply chain activities and will implement
these activities as soon as the necessary technology becomes
cost-effective and the required skills are available. Rather than having
to be pressured into adopting these new methods, firms are voluntarily
moving forward with supply chain projects to enable themselves to be
more competitive in the marketplace.
Another factor that should greatly encourage increased use of
supply chain management are the benefits that micro organizations report
achieving as a result of SCM. This study depicts that supply chain
management is believed to have provided superior customer service,
increased profits and higher levels of collaboration and trust with
suppliers and customers. Although the remaining two benefits included in
the questionnaire, reduced costs and impressive growth, were not
statistically significant, both received moderate support in the data.
These results indicate increased micro firm success via supply chain
management should spur other micro organizations to give more serious
consideration to the implementation of supply chain management methods.
However, the research reveals that in their efforts to move toward
greater use of supply chain methods it is crucial that micro entities
not get ahead of themselves. The findings demonstrate the importance of
providing the foundation for successful SCM by developing a formal
business strategy to guide supply chain decision-making, installing the
necessary information and telecommunication technology, and
rationalizing internal processes. It was encouraging to discover the
extent to which micro organizations have already achieved this supply
chain foundation.
The most discouraging finding of the research was the large number
of micro enterprises that believe their small size implies that they
would not benefit from formal procedures and policies. Although this
claim may indeed be valid on occasion, one cannot help but suspect that
some entrepreneurs are resisting supply chain methods not as a result of
a rational business decision, but instead due to the stereotypical
entrepreneurial distaste for formal structures. If this is the case,
these firms may ultimately be harmed by their unwillingness to give
supply chain methods the careful analysis that the methods deserve.
A micro organization's lack of technical expertise appears, as
expected, to be a roadblock to the implementation of SCM. The research
suggests that internet utilization, either for placing purchase orders
with suppliers or for accepting purchase orders from customers, is one
of the least fully implemented supply chain methods among micro
enterprises. This may be a serious omission considering the potential of
the technology to increase both efficiency and effectiveness. It is
encouraging, however, to observe that many firms recognize the need to
learn more about the internet. Universities and Small Business
Development Centers obviously have a major role to play in this
acquisition of knowledge. Faculty need to continue to increase the
coverage given to supply chain management in their courses, particularly
in courses oriented toward entrepreneurship.
IMPLICATIONS, LIMITATIONS AND FUTURE RESEARCH DIRECTIONS
The research study adds to the knowledge base in the fields of
entrepreneurship and supply chain management by developing a profile of
micro enterprise utilization of supply chain management. The research
findings provide evidence that micro firms employ SCM practices and
methods quite extensively, although possibly not at the same level as
that demonstrated by larger firms.
Micro organizations are enjoying the benefits of SCM through
increased profits, improved customer service and enhanced collaboration
and trust with suppliers and customers. Additionally, micro enterprises
appear to have recognized and developed an understanding of these
methods and the benefits that they can provide. However some SCM
adoption is driven simply by pressure from suppliers and customers, much
of it appears to be a result of factors suggesting foresight and
awareness on the part of micro enterprises. The benefits achieved and
the higher than expected awareness suggest that micro organizations can
be expected to implement SCM more rapidly in the future, especially if
the necessary skills become more widely available and the technology
decreases in cost. Obviously universities can play a major role in
preparing students who will have the necessary supply chain expertise to
aid these micro entities in their execution efforts. As noted in the
survey, web-related training in particular would seem to be very
valuable to micro enterprises.
This research contains some limitations. First, the survey
requested respondent opinions rather than objective measures of supply
chain implementation or performance improvements. Moreover, many of the
firms in the sample may have quantitative evidence on which to base
their opinions, however, some of the input may have been subjective. It
would be helpful in future inquiries to obtain data that is more
objective. A second weakness is the small size of the sample. Although
there were a number of hypotheses for which statistical significance was
achieved, there were a few for which the data supported the alternative
hypothesis but too weakly to allow a legitimate rejection of the null.
It is recommended that this study be replicated in other
geographical areas to determine if the findings are consistent. Detailed
case studies of individual firms could prove useful as well, allowing an
investigation of some of the subtleties that can not be captured in a
mailed questionnaire. Finally, it is recommended that the definition of
micro enterprises be expanded beyond employee size to include industry
sector as well as various financial constructs.
CONCLUSION
Micro enterprises perform supply chain management practices and
methods, albeit to a lesser extent than larger organizations. Moreover,
micro organizations understand the value of supply chain management and
its benefits, however, micro firms tend to accept that their size allows
them to operate very effectively and the need for formalization is
minimal which may impact the implementation of supply chain management
negatively. Micros are still concerned about the time and capital
required to implement supply chain management as well as providing
sensitive information to supply chain members. The more technologically
proficient a leader of a micro organization appears, the more a leader
is favorably proposed to supply chain management activities. In
summation, micro enterprises have employed supply chain management
practices and methods despite the paucity of evidence in the literature.
