Stephen P. Robbins Ph.D. has written a new book on “The Truth About Managing People” just had a glance on his chapter about motivation of workers. He highlights three questions about the point often heard by managers: “people are just not motivated to work”.

• “do employees believe that if they give a maximum effort, it will be recognized in their performance appraisal?”
• “do employees believe that if they get a good performance appraisal, it will lead to organizational rewards?”
• “are the rewards the employees receive the ones that they want?”

I think these are essential points not only for organizational structures but the right design of rewarding or performance appraisal system is essential also for learning networks and the mentioned questions are undoubtful highly related to intrinsic motivation that has shown to be a key factor of working communities of practice.
