Which of these is difficult when Agile Project Management is used? a) Knowing for certain that the software is working as you progress through the project b) The frequent rescoping of a predictable project becomes wasted expense as it won't deliver added benefits. c) Altering or updating the project requirements d) Fixed-price contracts between customers and the project organization.

d). Fixed-price contracts between customers and the project organization

Explanation:

APM or Agile Project Management is an iterative outline to the planning and guiding of project processes. It is often completed in small stages or sections. These small sections are called iterations.

An organization's fixed-price contract provides a price which can not be adjusted on the basis of contractor's cost experience in doing the contract.

Thus in agile project management it is very difficult for a fixed price contract because the agile project, the work is approach section by section and thus it is difficult for the contractor as the price of the resources increases with time.

Hence the answer is (d).
