As the various constructs give different assessments of balance and no strong suport was found for Belbin's team roles balance, these developed model should be used.

Practical implications – In literature the current team balance constructs are of limited use.

The relation between this construct and performance should also be tested. Research limitations/implications – There is need for an improved construct, which is isomorphic with Belbin's notions of team balance. It is argued that authors do not use constructs according to Belbin's theory of team balance. Team roles balance provides an environment which encourages individuals to contribute and provides higher motivation. Findings – A statistical relation between team roles balance and team motivation was found. Motivation indices of each team were tested against the team balance scores by using Spearman's rank test. Team roles balance was assessed with the developed model.

To assess team current level of motivation was used a tool proposed by Woodcoock and Francis (2008). Team roles were identified applying BTRSPI. Design/methodology/approach – Data were collected from a sample of 32 project management teams on POS DRU program, out of a population of 145 members. Purpose – The purpose of this study is to design a model for assessing and measuring team roles balance and to test the model analyzing the relationship between team roles balance and team motivation.
