The Cost of Ambiguity
When founders say 'I want an app like Uber but for dog walking,' an agency might estimate anywhere from $10,000 to $250,000. Both estimates are correct based on their unspoken assumptions.
To get precise estimates, fast delivery, and avoid mid-project scope creep, founders must bring concrete domain specifics to the discovery table.
The Five Essential Discovery Artifacts
1. User Persona Workflows: Exactly who logs in, and what specific action do they take in step 1, 2, and 3?
2. Data Entities: What items exist in your world? (e.g., Student, Application, Visa Document, Payment Receipt).
3. Third-Party Dependencies: What external services are required? (Stripe, Twilio, Google Maps, DocuSign).
4. Non-Functional Requirements: Security compliance (HIPAA, GDPR), target response times, and multi-region needs.
5. Success Metrics: What metric determines that this project succeeded in month one?
