Why is Work Performance Information an input to Perform Quality Assurance?

edited May 2012 in PM Certifications

Work Performance Information (WPI) is an output of Direct and Manage Project Execution (Executing process), and an input to most Monitoring and Controlling processes (like Perform Integrated Change Control, Control Scope, Control Schedule, Control Cost, Report Performance, Monitor and Control Risks, Administer Procurements).

But WPI is an input to Perform Quality Assurance (Executing process) and not to Perform Quality Control (Monitoring and Controlling process).
