Why Requirements Matter
The number one reason software projects fail isn't bad code — it's unclear requirements. When developers don't understand what you want, they build the wrong thing. And fixing the wrong thing costs 5-10x more than building it right the first time.
The good news: you don't need to be technical to write excellent requirements. Follow these six steps.
Step 1: Define Who Uses It
Before describing features, describe your users. Write one sentence for each type of user:
This tells developers who they're building for, which shapes every technical decision.
Step 2: Describe What It Does (Not How)
Focus on outcomes, not implementation. Use this format:
"As a [user], I want to [action] so that [benefit]."
Examples:
Avoid telling developers HOW to build it. Describing the "what" and "why" gives them the freedom to choose the best technical approach.
Step 3: List Core Features by Priority
Create three lists:
Must-Have (Launch Blockers)
Features without which the product cannot launch. Keep this list as short as possible — ideally 5-8 items.
Should-Have (Important but Not Critical)
Features that significantly improve the product but aren't required for launch.
Nice-to-Have (Future Enhancements)
Features you'd love to include eventually but can wait for version 2.
This prioritization helps developers estimate timelines and helps you make trade-off decisions when budget or time gets tight.
Step 4: Provide Visual References
A picture is worth a thousand words of requirements. For each major screen or feature, provide:
You don't need professional wireframes. Even rough hand-drawn sketches dramatically reduce misunderstandings.
Step 5: State Your Timeline and Budget
Be upfront about constraints:
Honest constraints help developers propose realistic solutions. Without them, you'll get proposals that are either over-engineered or under-scoped.
Step 6: Document Additional Requirements
These are often forgotten but critically important:
A Simple Template
Compile your answers into a single document with these sections:
This document doesn't need to be long — 3-5 pages is usually enough. The goal is clarity, not volume.
Conclusion
Writing clear requirements is a skill, not a talent. Follow these six steps and you'll communicate with developers more effectively than most product managers. POLYGLOTSOFT provides free requirement review sessions to help you refine your project brief before development begins.
