Pitfall	Description
Missed requirements	Missed requirements can lead to unnecessary refactoring, especially if the initial implementation cannot accommodate the missed requirements.
Unforeseen edge cases	Unforeseen edge cases can also lead to unnecessary refactoring or the insertion of new code that obscures the intent of the code.
Hard to understand code	When you refactor code to accommodate a new and better understanding of the problem, the resulting code is often harder to understand since your revised logic may be more complex than otherwise.
Difficult to maintain code	The refactors can sometimes lead to unintended dependencies that make it difficult to change the code.
Difficult to scale code	Not planning for scaling can lead to inefficiencies and complexity.
