Are you working with a legacy application? Whether you inherited it or if the project just grew out of proportion over the years it can be daunting. The thought of making changes or bug fixing can be enough to give you nightmares. No fear you can take a sigh of relief. All is not lost.
A few years ago I found myself working on a legacy project. It wasn't pretty. It was very challenging but I made it through.
And when the next project and the next one and the next and the one after that were also legacy systems, I soon found it much easier to work on them by being more methodical.
