What is the role of Requirements Engineering during the implementation phase?

RE work doesn't stop at coding — it shifts to answering developers' questions and managing change requests, documenting every clarification back into the SRS (and bumping the version).

Before development:

• Consider organizing an SRS walkthrough with the devs
• Ensure developers understand the requirements

During development:

• Your main task is to answer developers' questions
• A large number of questions = indication for insufficient/unclear specification
• Certain open points will need additional input from customer
• Watch out for potential Change Requests

Important practices:

• Every time you clarify or answer questions, make sure that the information gets documented in the SRS
• Don't forget to increment the version number (for traceability)

Warning sign: If developers constantly ask questions, your requirements document needs improvement.
