Developers Who Live in Glass Houses Refactor Their Code

Another perspective and reason to refactor PowerBuilder code

PBDJ Blog

Refactoring in not hard to do or difficult to conceive of - BUT you have to develop a sense about it. Part of wanting to refactor is professional pride. Ask yourself - If your software was a publicly visible structure such as a bridge or building, what would it look like?  

Would you be will to go step on it or go inside it?

Do you think that it's too late for improve your software?  Are you afraid to take a small risk? Remember that refactoring is all about taking lots of small steps that eventually add up to a big improvement. Do you sometimes get that sick feeling when you're asked to work on a particular section of code?  Ever wonder why?  Might the reason for the feeling be because the logic is "all over the place", fragile and tricky to make changes to? So wouldn't a bit of restructuring make the job more palatable?

Refactoring is mostly about making programs more "human friendly". The runtime cost factor for performance is minimal. Software engineers talk about the 90/10 rule i.e. 90% of performance issues are due to 10% of the code. PowerBuilder's profiling tools can help you identify tell you where these areas actually lie.

What do you think?
