Which of the following statements is/are false?

P: The clean-room strategy to software engineering is based on the incremental software process model.

Q: The clean-room strategy to software engineering is one of the ways to overcome “unconscious” copying of copyrighted code.

Choose the correct answer from the code given below:

Clean room software engineering model is an incremental software paradigm for the development of zero defect and high reliability software using box structure specification, statistical quality control and certification.

It is a practical development and certification approach that uses statistical quality control to reduce software defects, to overcome unconscious copying of copyrighted code.

Characteristics of cleanroom software engineering approach:

• Incremental development process model
• Formal methods for specification and design
• Correctness verification
• Statistically based, independent testing

The development life cycle starts with a specification that not only defines function and performance requirements but also identifies operational usage of software and nested sequence of user function subsets that can be developed and tested as increments which accumulate into the final system.
