Avoid the can vs should trap by asking whether it should be built, not just how to build it, and prioritize true need over mere technical feasibility.

Avoid the build trap by stepping back to understand the customer's true problem and purpose, and prioritize building the right thing over piling features in the backlog.

Focus on one customer segment at first; if your customer is everybody, your customer is nobody. Prioritize understanding who your customer is and optimize for conversions, not vanity metrics.

Identify and avoid the being human trap by testing assumptions early with customer data. Understand how the endowment effect and confirmation bias distort ideas, and why cheap, fast validation matters.

Ask questions and engage in the course discussion to maximize your success. Provide feedback and rate the course to help improve the material and support your goals.

Embrace the shift from glamorizing startups to building a successful business driven by real demand. Focus on aligning supply with actual demand to avoid common startup failures.

Demystify innovation by contrasting defensive (sustaining) and offensive (disruptive) approaches, including adjacent and transformative forms, with examples like Mercedes-Benz, Uber, and iPhone.

Learn how lean startup, rooted in Toyota manufacturing, eliminates waste through customer development, delivering value and guiding startups to discover customer needs and create repeatable, scalable value amid extreme uncertainty.

The number one priority in creating a new product is to find and validate demand before building supply, ensuring there is value and avoiding waste.

Master the four stages of customer validation: problem market fit, solution market fit, and product market fit to grow market share. Continue learning and improving at every stage.

Identify the target customer and validate that they have a real problem through in-depth interviews. Explore early adopters and avoid premature solution narrowing to uncover the market fit and bottlenecks.

Validate solution market fit by proving a customer segment will exchange value to achieve goals. Use concierge mvps, wireframes, and landing pages to test willingness to pay and signup.

Discover how concierge minimum viable products validate solution-market fit through high-touch service and hands-on customer interviews, using manual processes before building scalable solutions.

Validate product market fit by proving a market segment loves and needs your product, then optimize channels and value propositions that convert and scale.

Now you're a business, focusing on revenue, profitability, and ongoing innovation to avoid extinction. Balance defensive innovation across three tiers—improving adjacency, remodeling, and sustaining current offerings.

Balance vision and data to design products customers want, as Henry Ford illustrates, through the overlap between customer understanding and vision that drives successful innovation.

Use data to inform decisions, not drive them, and pursue your product vision aligned with what customers need, applying bathtub interviewing to test assumptions and constraints.

Explore how a data-informed approach drives progress toward a vision, using ongoing data collection to backtrack or advance and ultimately actualize the goal.

Swiffer and Uber show how deep customer understanding paired with vision uncovers bottlenecks in mapping and taxi hailing, unlocking disruptive opportunities.

Identify customer goals, jobs to be done, and pains to build a precise persona that guides product decisions and reveals what jobs customers hire your product to do.

Identify the riskier customer segment in a multi-sided marketplace and test that side first to validate demand and solve the chicken or the egg.

Construct a provisional customer persona by detailing goals, behaviors, pains, and facts for a specific user. Then plan and refine through interviews to guide product learning.

Map a customer journey by detailing every step from realizing the goal to achieving it, uncovering bottlenecks, emotions, and jobs to be done to unlock disruptive innovation.

Discover how to frame learning objectives for customer interviews, prioritize critical unknowns, and explore functional and emotional assumptions to shape your product and value proposition.

Learn to craft interview questions that disprove your assumptions, avoid leading prompts, and ask in past tense about past behavior, emotions, and specific instances along the customer journey.

Examine good versus bad interview questions in customer interviewing, focusing on behavior-based, non-leading prompts and context. Assess budgeting, solution search, and immediate buy-now validation to guide product discovery.

Create one precise interview question per learning objective for customer interviews, focusing on good and bad question principles, for the top five to seven objectives defined in the previous exercise.
