When to stop code refactoring

• Taking too much time to refactor, which is blocking other dependent applications and priority tasks.
• For developers CR is like a drug, a developer can refactor can keep on refactoring a complex codebase for ages. If CR is limited to no ROI (Return On Investment) the activity needs to be stopped.
• Refactoring is not same as redesigning the code. It is easier to start the coding from scratch than to refactor your somebody else's or your own code. This needs to be learned before CR starts.
