The Minimum Viable Product definition tells us what scope and scale of the product we will have to build as the first release version that will find customers to use it (and ideally pay for it - hence: viable) and give us feedback to work with. It needs to be as small as possible (hence: minimum) so that we can market as quickly as possible yet with enough power to solve problems that some customers will already want to use.
Defining the MVP is critical to understanding for whom you are building the first version and what needs to be included to solve enough pains for them so they’ll want to use it.
Review your Finalised Concept Card and Persona Statements. Which Persona could be your beachhead market? Who has the highest pain or lowest barrier to switching to a new offering?
For the Persona, re-run the Value Proposition Canvas exercise to map your concept's features that will solve enough pains and generate enough gains to appeal to that persona precisely.
Check the outcome against your Product Vision to ensure they align.
Write out the feature tree and specification for the things that need to be included to deliver that value proposition that you defined as sufficient for that beachhead market target persona.
