- 5. 4 7 7 The Dismal Record of Startups • The #1 cause of failure = No Market for their Product • It’s a great product or service that no one wants to buy 8 8 Eric Ries • An entrepreneur with an impressive track record – Product to connect students with … employers – Product to let people play in a 3D virtual world
- 6. 5 9 9 Eric Ries • Ries discovered that under conditions of extreme uncertainty, classical management methods do not bring success ‒ When we lack knowledge – we gather more information ‒ When we lack alignment – we give more detailed instructions ‒ When outcomes are not what we expected – we impose more detailed controls 10 10 Eric Ries • He formulated the Lean Startup methodology based on his and others’ experiences
- 7. 6 11 11 Foundations of Lean Startup 1. Customer Development 2. Build-Measure-Learn (BML) Loop 3. Minimum Viable Product (MVP) 4. Validated Learning 5. One Metric That Matters (OMTM) 12 12 1. Customer Development • Learning and discovering who a company’s initial customers will be, and what markets they are in, requires a separate, distinct, and parallel process from Product Development ― Steve Blank
- 8. 7 13 13 2. Build-Measure-Learn Loop In rapid iterations Persevere or Pivot? • GOAL: 14 14 3. Minimum Viable Product (MVP)
- 9. 8 • The MVP is that version of the product that enables a full turn of the Build-Measure-Learn loop with a minimum amount of effort and the least amount of development time 15 15 3. Minimum Viable Product (MVP) • The minimum viable product lacks many features that may prove essential later on – and that’s OK 16 16 3. Minimum Viable Product (MVP) (Final product)(Minimum viable product)

Validated Learning • Validated learning is “the process of demonstrating empirically that the team has discovered valuable truths about the present and future business prospects” 18 18 5. One Metric That Matters (OMTM) • Most metrics gathered by organizations are “vanity metrics.” They make us feel good (or look good), but don’t really show progress toward our goal Number of customers Cost to obtain each new customer Number of customers actually using the product

- 13. 12 23 23 1. Customer Development • Customer Development suggests that we should identify the “customers” of our TESTING SERVICES: – Developers – Users – Management And serve THEM, not our testing process 24 24 1.

Minimal Viable Product (MVP) • The idea of an MVP suggests we could start with a Minimal Viable Set of Tests • Don’t strive for “completeness” from the beginning • Add additional tests as the need becomes apparent and warranted Learn what your customers want/ need/value
