All About the Learning
That nagging voice in the back of your head, wondering if there’s a way out of the Analysis Paralysis trap you’re in, trying to figure out a way to actually know the answers to some of your questions, instead of analyzing yourself into a deeper sense of false security? That’s where the Minimum Viable Product comes into play.
Key Element to Enable PSPI: Definition of Done
First, we have to agree on a Definition of Done, or define the finish line. This allows us to align expectations of “potentially shippable” and “working software.” (See Principle #7 in the Agile Manifesto).
Key Element to Enable PSPI: Learn New Skills
Second, the team needs to learn new skills like breaking down work and swarming. Good agile teams figure out how to get features done early and throughout the Sprint instead of everyone working on their own in a mini-waterfall where QA is squeezed in at the end. Multiple developers collaborate on a feature together rather than each his own.
Key Element to Enable PSPI: Break Down Requirements
