Basic Principles of Defect Prevention

• Early Defect Detection and Resolution: It finds and fixes errors as early when possible in the process of development. Early issue detection lowers the cost and effort needed to remedy problems.
• Enhancement of Process: It employs best practices, industry standards and lessons acquired from previous projects to continuously improve development processes and raise overall quality.
• Code Evaluations: To find and fix errors, conduct routine code reviews. It encourages team members to work together and share expertise.
• Measurements and Metrics: It creates metrics to assess the success of efforts to prevent defects. Key performance indicators should be tracked and examined to find areas that need improvement.
• Loops of Feedback: Create feedback loops to gather knowledge from different development phases. It utilizes input to modify procedures and stop reoccurring problems.

Software quality is one of the most important and essential factors from the last few years. This is due to forces from several sectors of the computer industry. Companies and organizations face many problems that have increased difficulty in obtaining and achieving rapid and successful development of software systems. The main challenge in any software product development is simply to reduce and minimize and number and occurrence of defects.

Defects are one of the major causes of a decrease in software quality and an increase in overall cost due to additional cost required for resolving defects. Therefore, identifying and resolving defects is the main focus of any development team that will help in preventing software products from occurring again.

For this identification and resolution of defects, defect prevention is the most significant and essential activity of the software development life cycle that directly effect controlling the cost and quality of software products. Someone has well said that “Prevention is better than cure”. The main goal of defect prevention is to identify defects and take corrective measures to minimize their impact and completely reduce the chances of their re-occurrence in future releases.
