Pass one: list every claim in your value story. Pass two: against each, mark the strongest source you have today and the source you'll need at HTA submission. The delta is your evidence-generation backlog.
Score each gap
Impact
How central to the value story
Feasibility
Can it be generated in the launch window
Cost
Trial vs RWE vs ITC
Don't score by committee
If everyone scores everything 3/5, your output is a heatmap nobody will use. Force the trade-offs.
