When is custom development the right answer?
When standard software fails for a substantive reason rather than a cosmetic detail: a process or rule you run that packaged software cannot represent even with configuration, an integration between two systems that cannot be replaced, a legacy system that must stay and needs a bridge, or an operational function no package sells because it is specific to your field. If the difference is a form field, a report or a permission, then configuration or training beats code you maintain for years. The analysis tells you which case you have.
