Many a times it happens that the code we are maintaining/enhancing is not well structured, not comprehensible, doesn’t use sensible coding practices/guidelines. We should sense a danger when we are not in a position to guarantee that a particular change/fix doesn’t produce any side-effects. Currently, I am managing a code base which has such characteristics. Whenever my manager asks “Is this issue fixed”, I can’t think of a better reply than “Looks like it is fixed”. And not surprisingly, something or other is broken. I read an appropriate analogy to this situation (don’t remember where). It says “Hit a table in Tokyo and a building falls in New York”.

In such cases I feel, we should keep the current system running as it is, branch it out as old_projectname in version control system and start afresh. While you are fixing things on the branch, record them to fix on the new development too. But the most important question is whether the project management is willing to plan for this clean up. Mostly it is not. Because, until the issue is properly communicated to the managers they won’t feel the need for it. And, with strict deadlines and expectations in place it is an herculean task to abstract all problems in manageability and present it to get a buy in for this clean up. It would demand a critical analysis of code to filter out the hidden issues that surface to influence the reputation of a worthy developer. Yes, finally it is the developer who is blamed for bugs and side-effects and not the current state of code.

I feel, this process should occur in small steps at a time. Re-factoring. First build tests for the existing code. Then make one small change at a time. In that way we don’t miss any of the capabilities of existing system.

It is high time managers step into the shoes of developers and understand the importance of maintainability (not for the sake of developers but for the sake of quality, goodwill and progress)
