The Quality Control Processes use various tools to study the Work done. If the Work done is found unsatisfactory it may be sent back to the development team for fixes. Changes to the Development process may be done if necessary.
If the work done meets the standards defined then the work done is accepted and released to the clients.
Importance of Documentation:
In all the Quality Management Processes special emphasis is put on documentation. Many software shops fail to document the project at various levels. Consider a scenario where the Requirements of the Software Project are not sufficiently documented. In this case it is quiet possible that the client has a set of expectations and the tester may not know about them. Hence the testing team would not be able test the software developed for these expectations or requirements. This may lead to poor “Software Quality” as the product does not meet the expectations.
Similarly consider a scenario where the development team does not document the installation instructions. If a different person or a team is responsible for future installations they may end up making mistakes during installation, thereby failing to deliver as promised.
Once again consider a scenario where a tester fails to document the test results after executing the test cases . This may lead to confusion later. If there were an error, we would not be sure at what stage the error was introduced in the software at a component level or when integrating it with another component or due to environment on a particular server etc. Hence documentation is the key for future analysis and all Quality Management efforts.
Steps:
In a typical Software Development Life Cycle the following steps are necessary for Quality Management:
1) Document the Requirements
2) Define and Document Quality Standards
3) Define and Document the Scope of Work
4) Document the Software Created and dependencies
5) Define and Document the Quality Management Plan
6) Define and Document the Test Strategy
7) Create and Document the Test Cases
8) Execute Test Cases and (log) Document the Results
9) Fix Defects and document the fixes
10) Quality Assurance audits the Documents and Test Logs
Various Software Tools have been development for Quality Management. These Tools can help us track Requirements and map Test Cases to the Requirements. They also help in Defect Tracking.
What is Defect Tracking?
This is very important to ensure the Quality of the end Product. As test cases are executed at various levels defects if any are found in the Software being tested. The Defects are logged and data is collected. The Software Development fixes these defects and documents how they were fixed The testing team verifies whether the defect was really fixed and closes the defects. This information is very useful. Proper tracking ensures that all Defects were fixed. The information also helps us for future projects.
