The six stages
Stage 1: Internal identification
A problem gets named by someone who has it. A service line is losing clinician time to documentation. An imaging department cannot meet a turnaround target. A quality metric is drifting.
Note what has not happened yet: nobody has decided to buy anything. This stage produces a problem statement, and the most valuable position a vendor can occupy is being the source that helped define it. That is the entire argument for discovery-stage content, and it is why an RFI is worth answering carefully even though it is unpaid.
Stage 2: Requisition and internal sponsorship
The problem becomes a request with a name on it. The requester assembles a case: what the problem costs, what the proposed solution does, what it costs, what alternatives exist, and why the organization cannot solve it with something it already owns.
That last question is the one that kills the most requests, and it is rarely asked out loud to the vendor. Many health systems already own capability they are not using, particularly inside their existing electronic health record.
Stage 3: Value analysis
The Value Analysis Committee reviews the request against clinical benefit, cost, disruption, and standardization.
The committee is usually reading a written submission, not watching a presentation. The vendor is frequently not present. This is the single most misunderstood stage in healthcare selling: the quality of the document beats the quality of the pitch, because the document is what is in the room.
Stage 4: Parallel technical reviews
Security and privacy review, integration assessment, and where relevant clinical governance run alongside each other. Each can block independently.
These are mostly queues. Integration analyst capacity in particular is scheduled months ahead at most systems, and a health system will sometimes decline an otherwise preferred product purely because it cannot staff the build this fiscal year. That is a scheduling constraint, not a product judgment, and it is worth surfacing rather than misreading.
Stage 5: Sourcing and contracting
Now the commercial mechanism gets chosen. An existing contract, a GPO agreement, a competitive RFP, or a sole source justification.
By the time an RFP is published, its requirements were usually shaped months earlier by conversations with one or two vendors. Responding cold to an RFP you had no hand in shaping is a low-probability exercise. That is not cynicism about the process, it is an argument for being visible earlier.
Stage 6: Implementation and conversion
For anything that started as a trial, the real purchase decision is the pilot-to-enterprise conversion, and it is judged on measured results at full price rather than on promise at pilot price.
The pattern underneath
Read the six stages together and something becomes obvious. Only stages one and six involve the vendor substantially. Stages two through five are internal, document-driven, and largely invisible from outside.
That is not an obstacle to work around. It is a description of where the influence actually sits: in the quality of the material available to the people doing the internal work, at the moment they are doing it. Which is a research problem, not a sales problem.
