Technical debt is a lack of real understanding of business functions- daverupert.com

When developing an application for a long time , We're doing it by constantly adding features , But it has never been reorganized to reflect our understanding of these functions , In the end, the program will not contain any understanding at all , So the effort to continue working on it will take longer and longer .

Knowledge management is so important in an organization , But they rarely go through key restructuring steps to reflect current understanding .

Large scale refactoring is needed when necessary . If the turnover of the organization is large enough or the functions in the product are increasing , So rewriting is the best choice , So your team has an overall understanding of the code . You can't expect people to implement incomprehensible requirements in busy programming , Or improve productivity in the legacy code of people who have left .
