Teams arrive at a Day-in-the-Life planning conversation knowing they want to observe someone but rarely knowing which group would produce the most useful insight. The loudest signal wins — usually whatever the last customer escalation mentioned, whoever has the most vocal internal champion, or whichever group a senior stakeholder has already named.
This play runs before the observation. Its first job is to make sure the room has actually surfaced all the candidate user groups — not just the obvious one. The facilitator draws these out through open questions: which groups keep coming up in account conversations? Which roles does the customer struggle to speak confidently about? Which users are affected but rarely represented in planning discussions? Each group that surfaces gets a card.
Once every candidate is on the table, each group is described honestly — who they are, what they are trying to do, and what friction signals exist for them. The portrait step forces specificity: is that signal confirmed from real evidence, or is it something the team suspects but has never verified?
Each group is then scored on five dimensions: pain signal strength, strategic leverage, insight gap, access feasibility, and decision feed. Scoring is fast and comparative — its value is in the comparison, not the absolute number.
The most important dimension is insight gap. A group the team already understands well enough to act on is a poor observation target regardless of how loud its pain signal is. The best DITL candidate is the group where friction is real but daily context, compensating behaviours, and root causes are still poorly understood.
The play closes with one named group, agreed recruitment criteria, and a brief of what specific behaviours and contexts the observer should pay attention to. That brief is the output.
