Do not digitise a broken process
The most common and most expensive transformation mistake is taking an inefficient paper process and rebuilding it exactly as software. You end up with the same seven approval steps, now with a login screen, and everyone concludes the new system is worse than the old one.
Before anything is built we look at why each step exists. A surprising number turn out to be controls for a risk that no longer applies, or workarounds for a system that was replaced years ago. Removing those steps is usually worth more than any technology in the project.
That analysis needs the people who do the work, not just the people who manage it. The informal steps that keep an operation running are rarely written down anywhere, and a transformation that ignores them tends to break things nobody knew were load-bearing.
Replacing legacy systems without stopping
Old systems are usually load-bearing, poorly documented, and running something critical. Replacing them wholesale is high risk. The safer route is incremental: put a modern interface in front of the legacy system, move one capability at a time behind it, and shrink the old system's responsibilities until retiring it is a small, undramatic step.
This is slower and considerably more likely to finish. It also means benefits arrive throughout the programme rather than at the end, which matters when a multi-year effort has to keep justifying its budget.
The final piece is adoption. New software that people work around has not replaced anything — it has added a system. We plan training, phased rollout, and a genuine feedback route from the start, because the technical migration is usually the easier half of the problem.
