A parent may have one or more children admitted in the day care but a child will be associated to only one parent. There are many supervisors in the day care to care of the children. Each child is assigned a supervisor. A supervisor however may take care off one or more children. The day care also offers transport services. A child may avail the transport or may not avail. One transport has to be associated with at least one child but may carry many children.

Select one major concept from organizational theory over the past one hundred years and present a brief history of the idea and how it is relevant to you in your profession, career, or place of employment.
MID-TERM ASSESSMENT, MGMT 630 FALL 2016

Please select five out of the first ten questions to answer. Please keep your answers concise. No credit is given for extra words. Use APA style citations and a reference list of those citations to support your answers whenever possible.

PLEASE do NOT DELETE the question that you are answering. You may delete the questions that you do not answer.

The history of organizations is replete with theoretical ideas from many cultures and time periods. The past one hundred years has been particularly interesting in that the ideas behind organizational theory have become the subject of intense research and study per se (by themselves), independent of being developed by practitioners for their religious, political, or economic arenas, as had previously occurred. Select one major concept from organizational theory over the past one hundred years and present a brief history of the idea and how it is relevant to you in your profession, career, or place of employment.

The priorities of organizations are important, and organizational theory defines the methods that organizations use to define their priorities and communicate them to stakeholders. Please briefly describe the priorities of an organization with which you are familiar. Would everyone who is asked about the organization agree with you on the priorities of the organization? If so, why? If not, then why not?

The lifecycle of organizations is something not generally understood very well beyond organizational theorists. Often, the length of life cycle stages is influenced by the sector to which the organization belongs. Briefly describe and analyze the life cycle of an organization with which you are familiar. Specifically describe the factors that you think have influenced the periodicity of its stages. Can you say anything about its future given what you have learned and what you know about the organization?

Some theorists believe that the appropriate structure for organizations is paramount and necessary for success. Others believe that organizational culture is the primary factor in achieving organizational goals. Please explain and reconcile to the best of your ability differing perspectives on the importance of organizational structure and culture. Back up your perspective with support from established organizational theorists if you can.

Some managers believe that following the law is all that is required to keep their organizations doing things the right way. Others believe that doing things the right way must be accompanied by doing the right thing. What do scholars have to say about how organizations should behave? Briefly describe what you find out. What do you think?
