What You Don't Know Can Cost You $100K
Non-technical founders who don't understand the software development process are easy targets for agencies that over-promise, developers who write unmaintainable code, and scope creep that doubles your budget. This guide gives you enough knowledge to be a credible partner without needing to code.
Phase 1: Discovery (Week 1–2)
Discovery is where requirements are turned into technical specifications. A good development team will: interview stakeholders, map user journeys, list all features with acceptance criteria, assess technical risks, and produce a project plan with milestones. Red flag: agency that skips discovery and jumps straight to "we'll start coding Monday."
Phase 2: Design (Week 2–4)
UI/UX design happens before coding — not alongside it. Expect wireframes (structural layouts), high-fidelity mockups (actual visual design), and a clickable Figma prototype. Approve this before a single line of code is written. Changing design after code is 5–10x more expensive.
Phase 3: Development Sprints (Week 4–12+)
Development happens in 1–2 week sprints. At the end of each sprint, you see a working demo. Your job as a non-technical founder: test the demo, give feedback on behavior not implementation, and prioritize next sprint based on user feedback.
Phase 4: Testing (Throughout)
Good teams test as they build: unit tests (individual functions), integration tests (features working together), and end-to-end tests (full user workflows). You should also receive a staging environment URL to manually test before production deploys.
Phase 5: Deployment & Maintenance
Production deployment should be rehearsed in staging first. After launch: monitor errors, track user behavior, fix bugs, ship new features. Software is never "done" — budget for 15–20% of build cost per month for ongoing maintenance.
