Start with the business goal
Custom software is most valuable when a workflow is unique, repeated often or constrained by disconnected spreadsheets and manual handoffs.
Before building, compare the total cost of custom development with configuration of an existing platform. Requirements, maintenance, security and ownership should all be considered.
A phased approach—starting with the highest-value workflow—reduces risk and gives users an opportunity to validate the solution before expansion.
A practical next step
Document the current problem, the people affected, the desired outcome and any constraints. A clear starting point makes it easier to estimate effort and choose the right solution.
