Process Improvement – cycle-time, quality, and cost

Write a 1,050- to 1,400-word paper, using your own organization or one with which you are familiar.
Identify the three categories of improvements (cycle-time, quality, and cost) that may be applied to an organizational process.
Address the following in your paper:

•Describe what challenges the selected organization may face in implementing the improvements.
•Recommend how the organization may resolve resistance to change.

problem is far more often essential than its solution, which may be merely
a matter of mathematical or experimental skill. To raise new questions, new
possibilities, to regard old problems from a new angle requires creative
imagination and marks real advance in science.” What is the value of this
statement in terms of the research process? What is the relevance and
relationship of this statement to the technologically advancing business
world? Where do these questions allow us to go?
