Start with the workflow, not the feature list
Most enterprise platforms fail because they are designed around features rather than workflows. The best internal tools start by understanding what people actually do — not what leadership thinks they do.
Keep the integration surface narrow
A platform that tries to do everything rarely does anything well. Define clear boundaries, expose well-designed APIs, and let specialized tools handle specialized needs.
Design for exceptions
Enterprise workflows are full of exceptions. A platform that only handles the happy path will be abandoned the first time something unusual happens. Build for the edge cases.
Adoption is a design problem
If people do not use the platform, it does not matter how well it was built. Invest in onboarding, documentation, and making the default path the right path.
