Systems become hard to maintain not because they are not advanced, but because they drift away from business goals. Start with clear goals, constrained scope, and layered delivery:
- Goals first: clear KPIs and milestones. Technology is the means.
- Controlled scope: prioritize the 20% features that drive 80% value.
- Layered delivery: prototype → MVP → scale, with continuous validation.
This approach ensures stability, maintainability, and sustainable growth while keeping ROI measurable.
