Students in the 21st Century will face an unprecedented rate of change in employee diversity, global competition, and legal requirements. Organizational Behavior and Management (OBM), 6th edition, by Ivancevich and Matteson is intended for that precise student. OBM 6/e provides those students with a wealth of text, readings, exercises and cases allowing them to experience and understand organizational behavior and it's importance to them as future managers. Twenty-first century managers must not only be able to perform the necessary functions of management, but they must also lead in a manner that enriches the capacity of employees who may or are likely to be moving around from work assignments, starting their own firms, and multiple organizations. Leading change, thinking ahead, executing flawlessly a plan or program, using technology, displaying passion regularly are what leaders must do smoothly and easily. The 6th Edition of OBM prepares students for this enhanced role, by focusing on managing and leading a firm's most valuable assets, its people.
