One of the main criticisms of the contingency approach is that: select one:
a. it may lead to resentment and rarely produces lasting behavior
b. it is more ambiguous and difficult to explain than the simpler "off the shelf" competition from checklists and stage models
c. it may not encourage collaboration and spread of change across business units
d. it may lead to over-focusing on individual work groups rather than on how they may operate as part of a larger, corporate collective
