Final answer:
Having a separate SQA group can indeed add considerably to the cost of software development.
Step-by-step explanation:
The statement is true. Having a separate Software Quality Assurance (SQA) group can indeed add considerably to the cost of software development. SQA is responsible for testing the software and ensuring its quality, which involves various activities such as planning, designing test cases, executing tests, and reporting defects.
The SQA group requires skilled professionals who are knowledgeable in testing methodologies, tools, and processes. Hiring such professionals and maintaining a separate team increases the cost of software development.
Moreover, the time and effort involved in coordinating with the SQA group, addressing issues and feedback, and retesting can also extend the overall development timeline and increase costs.
