In your own words describe the intent of certification in cleanroom software engineering.
What will be an ideal response?
Certification for cleanroom software engineering requires the creation of three models
Sampling model. Software testing executes m random test cases and is certified if no failures or a specified number of failures occur. The value of m is derived mathematically to ensure that required reliability is achieved.
Component model. A system composed of n components is to be certified. The component model enables the analyst to determine the probability that component i will fail prior to completion.
Certification model. The overall reliability of the system is projected and certified.
At the completion of statistical use testing, the certification team has the information required to deliver software that has a certified MTTF computed using each of these models.
