Answers:
Scope normally changes during a project as there are
two or more parties involved in working towards a goal to mutual satisfaction.
A change control is a formal documentation that provides official statements
about any changes in the scope of a project. This control
should be put in place as early as possible to
classify the types of requests that take place during the project. Scope
changes impact most elements of a project with the cost being the most
important. Keeping the client involved becomes useful while controlling the
scope changes as this will ultimately affect the schedule, cost and quality of
the project.
