Skill Details

jobs-to-be-done

Strategic framework for discovering and designing product innovations. Customers don't buy products—they "hire" them to make progress in specific circumstances.

About the author: Clayton M. Christensen (1952–2020) was a Harvard Business School professor widely regarded as one of the most influential business thinkers of our time. Named the world's most influential business thinker by Thinkers50 in 2011 and 2013, he developed the theory of "disruptive innovation" and authored nine books including The Innovator's Dilemma. Christensen co-founded Innosight (growth strategy consultancy), Rose Park Advisors (investment firm), and the Christensen Institute (non-profit think tank). His JTBD framework, detailed in "Competing Against Luck", has been adopted by companies like Netflix, Intuit, and countless startups worldwide.

Use when you need to:

  • Understand why customers really buy (or don't buy) your product
  • Design a new product or feature from scratch
  • Write customer discovery interview questions
  • Analyze competition beyond obvious product categories
  • Diagnose why a product isn't selling or customers are churning
  • Create positioning and messaging strategy
  • Reframe product metrics around customer progress

Example prompts:

  • "Help me write interview questions to discover the job our customers hire our app for. Use jobs-to-be-done skill."

  • "Write a job statement for someone buying a $3000 online course. Use jobs-to-be-done skill."

cro-methodology

Scientific, customer-centric approach to conversion rate optimization. Rejects "best practices" in favor of evidence-based testing—understand WHY visitors don't convert before changing anything.

About the authors: Dr. Karl Blanks and Ben Jesson are co-founders of Conversion Rate Experts (CRE), the world's leading conversion rate optimization agency. They received the Queen's Award for Enterprise twice—first for Innovation (codifying the scientific methodology now used by companies like Amazon and Google), and again for International Trade. Their client list includes Google, Apple, Facebook, Amazon, Dropbox, and many other leading tech companies. Their methodology has generated billions in additional revenue. "Making Websites Win" became an Amazon #1 bestseller in 15 categories. All profits from the book are donated to the charity Mary's Meals.

Use when you need to:

  • Audit a landing page or website for conversion issues
  • Identify why visitors aren't converting (objections vs. UX problems)

About the authors: Adam Wathan is a full-stack developer and entrepreneur best known as the creator of Tailwind CSS, the utility-first CSS framework that has become one of the most popular styling tools in modern web development. Steve Schoger is a visual designer from Canada known for his practical design tips that went viral on Twitter, helping developers improve their UI skills. Together, they created "Refactoring UI"—a book and video series teaching developers how to design beautiful interfaces without formal design training. Their collaboration bridges the gap between development and design, making good UI accessible to everyone who writes code.

Use when you need to:

  • Make a UI "look less amateur" without a designer
