J-Fall 2023: Identifying bad design in codebases, objectively… – Ryan Susana

Maintainability is the largest driver of IT costs. Poorly written, brittle code can be a barrier to getting work done. I have seen badly designed (if designed at all) code demotivate even the noblest of development teams. The upsetting part about maintainability is that it’s hard to quantify… Or is it? And if you can’t […]
