摘要：The aim of the article is to present the specificity and role of the planning phase in development projects, to make a quantitative assessment of actions affecting the effectiveness of this phase in enterprises and to indicate potential research areas in the subject. The article distinguishes three areas of particular importance to the planning phase, i.e. building the environment favouring innovation, directing innovation and stimulating ideas and solutions as well as transferring ideas inside and from the outside of the organisation. In order to determine the degree of efficiency of enterprises in these areas we conducted detailed investigations, where company representatives assessed the extent to which their enterprises took actions which affected the success of the planning phase. The investigations let us conclude that the enterprises provided organisational conditions supporting innovativeness. However, some areas that are particularly important to innovativeness need to be improved. The results showed that the enterprises did not always provide financial support to their employees’ innovative activities. This fact is very important in view of the degree of precariousness of innovative actions. Cooperation with the educational system and other external entities which could provide the necessary knowledge to the enterprise were also rated low. Formalisation of the measurement of innovative activity and its effects in the enterprise was another area that received low ratings, so it may be difficult to manage this activity. The article is summed up with a suggestion for more systematised investigations related with the selection of sources of knowledge.
