The Standards and their respective The Standards and their respective Analysis 1Analysis 1

1.1. SEI S/W standards are easy to make, thus SEI S/W standards are easy to make, thus it gets priorityit gets priority

2.2. IEEE standards are also easily generated IEEE standards are also easily generated in the tool.in the tool.

3.3. ISO standards for S/W requirements is ISO standards for S/W requirements is published so this part is easily added. But published so this part is easily added. But developments , designing and testing developments , designing and testing quality standards are under quality standards are under development. As the standards comes development. As the standards comes they can be added in the knowledgebase.they can be added in the knowledgebase.
