Q3 2019 OKRs: Research/test plan (umbrella issue)

[jessicaschilling]

This issue is an umbrella for creating, executing and reporting on a research and test plan related to our primary Q3 OKR deliverables:

1. Passive metrics collection for the front-page quiz on ipfs.io (implementation of the quiz is under Quiz: Mock up and implement front-page quiz #205)
2. Usability testing for the front-page quiz on ipfs.io (implementation of the quiz is under Quiz: Mock up and implement front-page quiz #205, with testing execution under Quiz: Set up and pilot remote usability testing #247)
3. Initial round of moderated validity testing for our IPFS goal-based personae effort (persona testing and launch is under Personae: Discuss/test and launch goal-based personae #203)
4. Card sort (Audit: Card sort on existing docs.ipfs.io navigation #191) based on content inventory of current-state docs site

While in-stream reporting on each of those deliverables should happen within their respective GitHub issues, all results should be captured in the test plan working document that is being managed in this issue.

This issue can be closed when all the testing in the test plan is complete and learnings have been captured adequately: noted in the test plan, captured in GitHub issues for future fixing, or some combination of the two.
