To me the SDLC starts when the development project starts — when we have some-what fixed requirements or begin development sprints from an established backlog. Depending on context obviously. I have a bit more about it here: https://jlottosen.wordpress.com/2017/05/24/testing-across-the-it-landscape/

Scott mentions how we can add value in establishing the business case and business ideas. These can be tested/challenged. Some business schools teach classes in simulations and experimentation with business ideas. Something along these lines: https://www.coursera.org/specializations/wharton-business-financial-modeling but also in rapid prototyping there is always an implicit scientific model (hypothesis/trial).

In essence: The PO’s how do the decide, how do they choose one item over another. What assumptions and probes do they take when deciding?

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
