The Product Discovery Handbook

A single discovery cycle can take as little as one week. A lightweight cycle -- 3-5 customer interviews, one prototype test, one assumption validated -- fits into a normal work week alongside other responsibilities. Larger initiatives (new product lines, major pivots) may need 2-4 weeks of focused discovery across multiple cycles. The key is to time-box: set a deadline, test the riskiest assumption first, and make a go/no-go decision at the end of the box.

Yes. The ideal is a product trio (PM, designer, engineer), but solo PMs can run effective discovery by keeping cycles short and focused. Conduct 3-5 interviews per week, run one experiment at a time, and share findings with your team for input. The critical thing is consistency: 2-3 customer conversations per week, every week, will compound into deep customer understanding over a quarter.

Frame it as risk reduction, not research. Instead of "I want to do user research," say "I want to spend one week testing the three riskiest assumptions before we commit eight engineer-weeks to this initiative." Quantify the cost of building the wrong thing -- rework, churn, opportunity cost -- and present discovery as the cheaper alternative. Most leaders will agree to a one-week time box when the alternative is a three-month bet without evidence.

You need very little: a video call tool (Zoom, Google Meet) for interviews, a note-taking app (Notion, Google Docs), and a whiteboard tool (Miro, FigJam) for your Opportunity Solution Tree. For quantitative discovery, use whatever analytics tool your company already has (Amplitude, Mixpanel, Google Analytics). For prototyping, Figma covers most needs. Do not let tooling become a blocker -- you can run effective discovery with free tools.

Product discovery borrows from both but is more specific about the PM role. Design thinking focuses on empathy and ideation. Lean startup focuses on validated learning and MVPs. Continuous product discovery, as described by Teresa Torres, integrates both into a weekly practice specifically designed for product trios working in an agile delivery context. The frameworks are compatible -- discovery is the practical operating model that puts these ideas into weekly practice.
