Legacy Software – Why I love working with it!

For years I worked as a consultant and coach. Both on agile methods and coding. I guess I was of some help on a few occasions. At least that is what some customers stated. But in the end I always left them alone. I often felt relief when I left them. But on the other hand it was also like surrender. The software was not finished. Most software is never finished; development goes on and on and on and …

This is probably nothing new to you. Maybe you have similar experiences. But probably you belong to the majority of people in software development: employed developers.

Buried Under Tons of Code

Old code. Untested. Unreadable. Unloved.

Is this what you dreamed of when you started your career? – Probably not. You may have dreamt of creating new shiny software from scratch using great technologies and fancy tools.

But you don’t quit your job. Perhaps you are a masochist? – I don’t think so. There are many reasons to face the challenge working in such an awkward place:

  • Responsibility: You feel responsible for the product. Although it is not the “Big Fun”, it is your job to keep the thing alive and even add more features to it.
  • Challenge: You think it is much harder to work in a situation like yours than to do small projects from scratch. You know that every software will become legacy after a certain age or size.
  • Fear: You are afraid of being the one to produce the nightmare from scratch that you are now working on. For you it is easier to say: “I just clean up other people’s mess!”
  • Hope: You are just staying because you have hope that you will be amongst the chosen few to start the next product from scratch.

In my case, it is a mixture of the first two aspects. In addition I have a strong belief that every legacy product can be changed to the better so that further development will be possible for a long period of time. This work is not funny but deeply satisfying. In our current product everyone in the team is trying his best while working on the huge codebase. And you know what: The software and the code become better each day.

We are all learning. We are all improving ourselves. Maybe some of us will become masters in the end. Who knows…

One thought on “Legacy Software – Why I love working with it!

  1. There seem to be a lot of “Code archeologists” out there, but they don’t know it. I propose “Code archeology” as a part of every IT education.
