PMI-SP Exam - Topic 4 Question 61 Discussion

The only tool and technique for controlling the schedule is a corrective action. You

should always report problems to management, the project

customers, or key stakeholders as defined in the Communications Management Plan, but you should

also always present a solution to the

problem.

A corrective action is a change implemented to address a weakness identified in a management

system. Normally corrective actions are

implemented in response to a customer complaint, abnormal levels of internal nonconformity,

nonconformities identified during an internal

audit or adverse or unstable trends in product and process monitoring such as would be identified

by SPC. It is method of identifying and

eliminating the causes of a problem, thus preventing their reappearance. Examples of a corrective

action are :

Improvements to maintenance schedules

Improvements to material handling or storage

Answer option C is incorrect. Trimming the project scope, which is a change request, is not a tool

and technique for control the scheduling. It

is, however, an output of the control schedule process and is sometimes a valid decision if the

project is slipping on schedule performance.

Answer option A is incorrect. Work performance measurements are not a tool and technique for

controlling the project schedule.

Answer option D is incorrect. The causes of the variance can help you determine the best action to

take, but it is not a tool and technique for

schedule control.
