Sir, I have a few doubts. I tried to post a comment  on OB Blog. Please guide me, sir. Besides this, I have a few questions: 1. What are the powers the group undertakes to become effective? 2. Explain the satisfying and optimising models of decision - making? Response to Qs 2: Your question relates to what is an ideal decision making process. To my mind decisions should be goal oriented, keep team member and boss interest's, competencies, moods, expectation in mind. Ultimately the great decision is an optimized one keeping all stakeholder interests in mind. There is always a trepidation before taking any decision (refer illustration). The greatness of a decision therefore is to take the plunge (decision), which keeps most of the affected parties happy. Of course there are exceptions to ideal decisions, particularly those taken by insensitive and unprofessional managers. The outcomes in the latter case/s would not be that helpful as the ideal decision.
