long term projects. Researches like [6] based on historical data of 396 projects of IS-<br />
BSG data set, showed that there exist a relation between E and D, which is nonlinear<br />
in case of medium and large projects, but can be considered as linear in case of small<br />
projects. For small projects, simple duration estimation model is needed, which can<br />
be adjusted easily to the team, project type, and gives a correct result based on the<br />
estimated effort and team size. By using the model presented in this paper, we reduce<br />
the project uncertainty by allowing the manager to obtain more accurate project duration<br />
estimations. Based on the P id value the personal professional evaluation can<br />
be observed.<br />
The model can be further improved by taking into account external factors which<br />
can influence the team productivity factors like team experience, team motivation,<br />
technical knowledge, etc. and to develop a model for more accurate productivity<br />
predictions.<br />
