Custom software is not always the right answer. The decision should compare the value of a better business fit with the full cost of building, operating and evolving a system.
1. Define the workflow that matters
Map the work people actually do, the information they need and the outcomes customers expect. Identify where existing tools create friction and whether that friction is material.
2. Compare buying, adapting and building
Test available products against the essential requirements. Consider configuration, integrations, licensing, data portability and vendor constraints before choosing a custom build.
3. Consider the whole lifecycle
Include discovery, design, implementation, hosting, support, security updates and future changes in the cost model. Identify who will own the system after launch.
4. Deliver the smallest useful product
Start with a focused release that addresses the highest-value workflow. Test with users, measure the outcome and use what you learn to guide the next investment.
