Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question andmention the sub-parts to be solved. Answer 21. The Punctuated Equilibrium Model (PEM) is an important model of organizational development in which change occurs in brief bursts and is largely stable.According to the punctuated equilibrium model of development, organizations undergo relatively long periods of stability (equilibrium periods) in their core activity patterns, which are then interspersed with brief bursts of a fundamental change (revolutionary periods). Punctuated equilibrium is the theory that evolution occurs optimally and logically sense as opposed to gradually and steadily. Hence the correct answer is option 4. Answer 22. Major workplace disputes frequently result from a lack of regard or understanding for another person's social or cultural diversity. Employing people who are different from you in terms of appearance, speech, and thought can help you avoid the costly traps of conformity, which hinders creative thinking. Hence the correct answer is option 4. Answer 23. Group norms outline what is expected of group members, as well as what is acceptable and unacceptable. They also help members predict the behaviors of other group members and the benefits or drawbacks of their actions. Norms assist prevent awkward situations and contribute to improved member satisfaction and team performance. Hence the correct answer is option 4.
