How Much Does It Really Cost to Do a Major Code Refactor?

▤ Summary

However, we’ve often seen large projects, with grand plans, that over time become increasingly difficult to manage. Changes become increasingly expensive, bugs appear in more and more unexpected places, and there comes a time when “refactoring” seems like the only way out. This last step is the major refactor, the rewriting of almost all the code, and we know it has an incredibly high cost. If you talk to a developer, they’ll often say that rewriting everything is faster than writing the program from scratch. It turns out that the major cost of development isn’t writing the code but understanding the software’s requirements.
