How to Define Scope Without Requirements -- Question List Included
A practical question list and methodology for quickly defining scope when starting outsourced development without a planning document or requirements specification.
- •Even without a planning document, answering "32 key questions" will help define your scope.
- •Sharing just 3 reference sites can cut communication costs in half.
- •Simply prioritizing with "Must/Should/Could" enables development within your budget.
What Happens When You Outsource Without a Planning Document
Starting with "just build something like this" without a planning document leads to:
1. Scope Creep: Disputes arise such as "Wasn't this supposed to be included?"
2. 50%+ Estimation Error: When scope is unclear, vendors pad their safety margins heavily
3. Timeline Delays: If direction changes mid-development, design has to restart from scratch
4. Deliverable Mismatch: "This isn't what I wanted..." leads to rework costs
But do not worry. Answering the questions below is a sufficient substitute for a planning document.
32 Questions for Scope Definition
Project Overview
1. What is the purpose of this project?
2. Who will use it? (Target users)
3. Are there similar services? (Reference URLs)
4. When do you want to launch?
5. What is your approximate budget range?
Users & Permissions
6. How many user types are there?
7. What can/cannot each type do?
8. Is sign-up and login required?
9. Is social login (Google/Apple/etc.) needed?
10. Is an admin panel needed?
Core Features
11. What are the 3 core features of this service?
12. What actions do users take on each screen (page)?
13. Should users be able to create/edit/delete data?
14. Are there screens that require search, filter, or sort?
15. Are notifications (email/SMS/push) needed?
External Integrations
16. Is a payment feature needed? (Which payment gateway?)
17. Are maps needed?
18. Is SMS/email sending needed?
19. Are there external API integrations? (Which services?)
20. Is file upload/download needed?
Design
21. Do you have design mockups? (Figma/XD/images)
22. If not, should the vendor handle design as well?
23. Is there a brand guide (colors/fonts/logo)?
24. Is mobile-responsive design required?
Infrastructure & Deployment
25. Do you have a domain?
26. Where will the server be hosted? (AWS/self-hosted)
27. Is SSL (HTTPS) mandatory?
28. What is the data backup frequency?
Operations & Maintenance
29. Is post-launch maintenance needed?
30. Is there a response time standard for outages?
31. Who will update content (text/images)?
32. Are there plans for future feature additions?
How to Use Reference Services Effectively
Instead of a planning document, the most effective approach is to find similar services and describe them like this:
"Build it like Service A. However:
Remove Feature B
Add Feature C
Make the design feel like Site D"
Sharing just 3 reference services enables the vendor to quickly understand the scope and cuts communication costs in half.
Must / Should / Could Prioritization
You do not need to build everything at once. Classify features into 3 tiers.
Must (Essential): Core features without which the service cannot function
Should (Preferred): Nice to have, but can be added after the initial launch
Could (Optional): Supplementary features to include if budget and time permit
This classification enables phased development that fits your budget and produces more accurate quotations.
