Periodic reviews are conducted by each of the teams assigned to coordinate DP activities. A list of common errors and recommended preventive actions are also introduced along with team assignments, a task schedule and project goals.

Included in the meeting is information related to the software process, standards, procedures, methods and tools applicable to the task, with an emphasis on recent changes inputs required and available for the task expected outputs and methods for evaluation of outputs and of adherence to the software process. A kick-off meeting is held to familiarize members of the team with details of the implementation process. At the beginning of a software task, the members of the team meet to prepare for the task and related DP activities. Training should include software quality assurance, configuration management and document support, and focus on DP and statistical methods (e.g., cause/effect diagrams and pareto analysis).Д¬reation of an action plan plays a key role in the implementation process. To assist in the successful implementation of a DP strategy, members of the software-engineering group and other software-related groups should receive training to perform their DP activities. Once in place, a review of results provides identification of effective activities and lessons learned to further improve the organizationвЂ™s success in applying a DP strategy.

The policy should contain long-term plans for funding, resources and the implementation of DP activities across the organization including within management, to improve software processes and products. Management must be committed to following a written policy for defect prevention at both the organization and project level. Figure 1 clearly depicts that identifying defects late in the game is costly.ДЇigure 3: Filter or Whirlpool Diagram for Software Defects Features of Defect Prevention This process is enhanced when DP methodologies are implemented to improve quality and productivity and reduce development costs. Mature IT organizations have an established software process to carry out their responsibilities. In general, DP activities are a mechanism for propagating the knowledge of lessons learned between projects. DP, identified by the Software Engineering Institute as a level 5 Key Process Area (KPA) in the Capability Maturity Model (CMM), involves analyzing defects encountered in the past and specifying checkpoints and actions to prevent the occurrence of similar defects in the future. It is the essence of total quality management (TQM). Defect PreventionДP is a strategy applied to the software development life cycle that identifies root causes of defects and prevents them from recurring.

Specifically, how implementing a model-based strategy to reduce requirement defects, development rework and manual test development efforts will lead to significant achievements in cost reduction and total productivity. This article will present various tools and techniques for use in creating a defect prevention (DP) strategy that, when introduced at all stages of a software life cycle, can reduce the time and resources necessary to develop high quality systems. Identifying and correcting process defects will prevent many product defects from recurring. Most defects are caused by process failures rather than human failures. Occurrence of defects is the greatest contributor to significant increases in product costs due to correction and rework time. The challenge in any software product development lies in minimizing the number of defects.

Organizations face many problems that impede rapid development of software systems critical to their operations and growth.
