Surviving Legacy Code

We all have legacy code, meaning profitable code that we’re afraid to change. It doesn’t matter who wrote it, in which language, nor when. It matters that we feel the fear now and need to deal with it. Rewrite or refactor? How do we write useful tests? There’s so much to change; how do we get started? When do we stop? Will it ever get any easier?

In the typical programmer’s day job, there’s no time to learn how to do this. We’re already behind schedule and the cost of fixing the legacy code is crushing us. We need a way to learn how to do this safely, correctly, and eventually, even quickly. That’s what Surviving Legacy Code is about.


Any programmer forced to deal with code that they feel afraid to change. That is, all programmers, eventually.

Delivery Options

Live/Remote Private Course

The standard course runs as 4 sessions of 1/2 day each scheduled within a 2-week period. The course is suitable for groups up to 20 people. Larger groups should run the course multiple times.

Add team working sessions to your course in order to better support teams working together during the course. During the 1/2-day team working sessions, we practise the techniques of the course using ensemble/mob programming. In these sessions, teams have the opportunity to rescue their legacy code with my guidance and support.

It is also recommended to add follow-up working sessions to be scheduled 1 month, 3 months, and 6-12 months after the course ends, as a way to support the group as they apply what they’ve learned to their daily work.

Live Support Package

Some clients use the online self-study course to learn the fundamentals on their own, then schedule live working sessions with me for guided practice, design review, and to get their questions answered. This schedule gives you an idea how you might use this approach with your group:

After this point, the group schedules additional live working sessions as needed.
