A rare disease biologics launch across five EU markets — where a propensity model surfaced a high-value HCP cluster invisible to standard territory planning, and field force adoption was earned through visible, rep-level performance data.
A next-best-action system cannot function without a defined Behavioral Objective — what specific action constitutes success, for which audience, and within what timeframe. Specifying the objective is an input to the model architecture, not an output of it; NBA deployments fail more often at the data layer than at the model layer.
A propensity model answers one question for each HCP: what is the probability that this HCP will achieve the defined Behavioral Objective within the defined timeframe? A true architecture ingests continuous engagement signals and updates recommendations in near-real time — a system that only reads historical data and updates weekly is a scheduling tool, not next-best-action.
The most technically sophisticated NBA system fails commercially if the field force does not use its recommendations. Adoption is a trust and relevance problem, not primarily a technology problem — reps do not act on recommendations they do not believe are accurate.
