On the subject of the finer details of the user process flow, there were a variety of opinions (are there always??).
I summarised, 'At the end of the day, there's only one opinion that matters, not Fred's / Bill's / James's, the user's opinion.'
This reminded me of the Practical Rules for Product Management. I repeat the ones relevant to user design here:
- RULE 8: Your opinion, although interesting, is irrelevant.
- RULE 9: The building is full of product experts. Your company needs market experts.
- RULE 12: The answer to most of your questions is not in the building.
