> Sure - but would it be wrong to say the same person may have different Personas depending on the context?

Persona is Persona, Job is a Job (as in JTBD).

Products are answering Jobs, and the same Persona/Consumer may have multiple Jobs, depending on the context.

  Consumer->Job->Product

Naive solution is:

  Consumer->Product

but the JTBD method makes implicit—explicit and makes invisible—visible.
