19 IT lessons learned in 19 years working with SMEs

What we would do exactly the same and what we would approach differently today.

After 19 years working alongside SMEs, one thing is clear: IT challenges are rarely purely technical. They’re usually about growth, timing, and the reality of running a business where priorities shift fast. They’re about tools that “still work” but no longer fit as well, environments that slowly become harder to manage, and decisions that were perfectly reasonable at the time… then quietly became permanent.
