Phase Containment?is incorporating?QA?into all the phases of SDLC. It results in Defect Prevention. If QA team performs Requirements Review, Design Review and Code Review, defects would be few?when?actual application is tested. That means we have prevented many defects by performing reviews at each stage of SDLC.

Phase containment is used for defect prevention so that the defects are found at each phase of the application, an are not multiplied further, we do it by taking JAD sessions, performing reviews after each phase, by participating in walkthroughs, inspection.

Phase containment is the act of containing faults in one phase of software development before they escape and are found in subsequent phases.

An error is a fault that is introduced in the current phase of software development.

A defect is a fault that was introduced in prior phases of software development and discovered in subsequent phases.

You promote the concept of phase containment by relating this concept to the organization's costs and profitability.  In order to do that, you will need to identify the faults that escaped phase and were found in later phases.  You will also need to determine the average costs of defects that escape and are found in subsequent phases.
