Commentators have differing views on what constitutes a quality project. The generally agreed parameters are that it delivers the desired outcomes on time and within budget.
The Quality Management Plan defines the acceptable level of quality, which is typically defined by the customer, and describes how the project will ensure this level of quality in its deliverables and work processes.
Project quality management is all of the processes and activities needed to determine and achieve project quality. At its most basic level, quality means meeting the needs of customers. This is also known as "fit for use."
