12.6 Summary

• Refactoring is the process of converting existing “bad” code into “good” code. It is done
via the parser, the relational model, and the language module.
• Refactoring is an activity crucial for evolutionary development processes.
• A change made to the internal structure of software to make it easier to understand and
cheaper to modify without changing its observable behaviour is called Refactoring.
• Metrics to measure software reliability do exist and can be used starting in the requirements
phase.
• Refactoring helps the code to retain its shape. Without refactoring the design of the program
will decay. As people change code.
• The power of refactoring as a method lies in systematically organized documents, which
describe proven techniques for enhancing software.

Documenting Refactoring: The power of refactoring as a method lies in systematically organized
documents, which describe proven techniques for enhancing software safely.
