Regulators approve.
Everyone else decides.
Too many promising products meet regulatory requirements yet still miss their forecasts. Often, the problem isn't the science, but a failure to ask payers, physicians, health systems, and patients early enough what would make them change their behavior. Those answers are knowable early, but often sought only after pivotal trial designs are locked and the cost of acting on them has risen sharply.
PAYERS
Reimbursement and value
PHYSICIANS
Clinical acceptance and workflow
HEALTH SYSTEMS
Operational fit and resources
PATIENTS
Access, affordability, and adherence
Adoption comes down to three questions.
Is it meaningfully better?
Does it deliver enough additional value to change someone's current approach?
How hard is it to adopt?
What are the real-world barriers — clinical, operational, reimbursement, or behavioral?
Who is willing to go first?
Which customers will lead, and what will it take to bring them along?
