摘要：Many Spatial Information Production (SIP) Organizations around the world are under pressure to assess their capabilities fro m the business perspective. Several Business Process Reengineering (BPR) projects are initiated to facilitate their adaptation to changing requirements in the global informatio n market, with a focus on the effective use of Information Technology. Several methodologies and co mmercial modelling tools are now available to help the process engineer analyze the behavior of real systems and its business processes. Describing the process b y means of models is essential to predict the consequences of new design options. This paper presents steps for the design of a methodology for appropiate use of an architectural modelling technique which describes processes as sets of activities and interactions with conditions of occurrence at any moment in time. The modelling technique is used as a base for performance study and reengineering of spatial information production processes, as demonstrated in two research projects. RADWAN, M.

Nowadays, NMA's are facing many challenges concerning the fast developing GIS-market and the threat of new competitors who have a flexible approach to adapt to changing requirements and continuous develop ment in information technology. In many countries NMA's are under the pressure of having to generate revenue and revise their mission to a business perspective and to be competitive, without violating its national mandate. NMA's sho uld produce the foundation data for the GIS community and deliver diverse and custo mised products to the customer in time, at affordable costs, with the required quality to the custo mer's specifications. To accomplish this they also need to develop the necessary infrastructure to facilitate access to their databases. The introduction of Information Technology (IT) and modern mapping systems can facilitate the introduction of new and more effective organisational design options. IT as enabler, however, means more than simply automating existing tasks. It means an innovative response to technology in ways that would not have been possible without that technology. Several projects are initiated in a number of NMA's to assess their capabilities from a business perspective, identify performance problems and improvement goals, and develop plans for change with focus on the effective use of IT. In this pursuit they can benefit from modern concepts applied in other industries such as Business Process Redesign (BPR), formal methods for the d ynamic modelling of processes, simulation modelling of processes and testing performance, Workflow Management (WFM), Total Quality Management (TQM). BPR is defined as 'the radical redesign of business processes to achieve dramatic improvements in critical contemporary measures of performance, such as quality, service diversity and speed'. Researchers have developed several methodologies, which provide techniques for organisations to examine existing procedures and reengineer its business processes, and to develop an organised approach for the implementation of change as suggested by the BPR plan. In studying a process and seeking ways to improve it, one can come up with many alternatives, possibly involving changes in the standard procedures as well as incorporating a variety of features in order to support its accessibility to new environments. Any proposal for change, however, should be assessed for what strategic b usiness advantages they offer and what support they can give to the execution of the business practices. Several commercially available modelling and simulation tools help the process engineer to systematically pursue design goals, representing, analysing and describing the process by means of models and quantifying the consequences o f new design options. The concept of BPR is yet to be adequately assessed for application in the spatial information production environment. The objective of current research activities at ITC is to investigate ways to strengthen the competitive po wer of Spatial information production organisations and improve its performance, through BPR, emphasising: . Development of a methodology for undertaking BPR in NMA. . Development of models to quantitatively evaluate the impact of BPR practices at both organisational and operational levels in NMA . Application of modelling techniques to describe processes and their dynamic behaviours . Definition of parameters or criteria for evaluating change scenarios and performance of processes using simulation techniques . Use of commercially available tools for modelling, simulation and the management of workflo w. This paper focuses on the investigation and design of a methodology for architectural modelling o f spatial information production processes, using cases fro m practice. 2 ARCHITECTURAL MODELLING APPROACH 2.1 The significance of modelling RADWAN, M.
