What is proto-persona?
Proto-personas in Lean UX are like personas but without validation through months of lengthy expensive research studies. This is a ad-hoc persona created by need to begin work on a product immediately, not spending too much time in research. These personas are built with assumptions with knowledge of team and stakeholders. Over the course of the project, the proto-persona can be updated more accurately to reflect the user with what we learn throughout the process. For e.g: survey, user interview, usability testing and so on.
Why use proto-persona?
- Shared understanding:
This process helps everyone in the team to build a common vocabulary of the users they will design and develop. As a result decision making will be easier and designing product will be more focused.
- Decision Making:
Having a clearly stated persona attributes also helps in decision making quicker. This will help prioritizing and agree on which feature will be more beneficial for the well defined personas.
Helps the team focus on the external customer/ users instead and not confuse the user as one of them from the team.
- Avoid risky knowledge gap:
There is a risk in knowledge gap between the team who creates persona and who uses them for e.g: external research team and the team working on the project. There is a risk of not learning about users throughout the product design cycle. In Lean UX approach, the team creates the proto-persona together and validates them throughout their learnings.
- Iterative approach:
In Lean UX, persona is not one-time activity whereas the persona goes through multiple iterative process through learnings.
- Recruiting correct user type for usability testing:
This also helps in prioritizing for future usability testing on the focus user groups to validate the assumptions.
