Question 249 Explanation:
→ Refactoring allows a software engineer to improve the internal structure of a design (or source code) without changing its external functionality or behavior of the code yet improves the
internal structure. In essence, refactoring can be used to improve the efficiency, readability, or performance of a design or the code that implements a design.
→ It is a disciplined way to clean up code [and modify/simplify the internal design] that minimizes the chances of introducing bugs. In essence, when you refactor you are improving the design of the code after it has been written.
Note: It won’t add any new featuring to satisfy a customer requirement. So, statement Q is false.
