Field Force Effectiveness in Pharma When the Script Is Just the Beginning

Field force effectiveness in pharma is still measured the way it was measured when a rep could see most of the doctors on the list. Calls per day. Reach and frequency. Message delivery. Those measures made sense when access was the constraint and more activity meant more prescriptions. Access is no longer the constraint. Veeva's Pulse data had 45% of HCPs accessible to biopharma in 2024, down from 60% eighteen months earlier. The constraint now is what happens after the prescription, and almost no field model is built or measured for that. This post sets out a different definition of field effectiveness, the evidence behind it, and how to rebuild the field around it without blowing up the model you have.

The field is being judged on the wrong half of the job

Here is the arithmetic your field dashboard does not show. A 2026 JAMA study summarized by Johns Hopkins found that insurer rejections of brand name prescriptions rose from 24.3% of initial attempts in 2018 to 40.7% in 2024. Of the rejected scripts, 48.4% were never followed by a fill of that drug or any drug in its class within 90 days. IQVIA data reported by Managed Healthcare Executive found that 61% of prescriptions with a final cost above $250 are never picked up. In the American Medical Association's latest survey, 82% of physicians said prior authorization at least sometimes leads patients to abandon treatment.

Now put your best rep in that picture. She wins the prescribing decision. The script hits a prior authorization wall. The office staff give up after the second call. The patient never starts. On every field metric you track, that was a success. On the only metric that matters to the physician, the patient and your revenue, it was a loss. Multiply it across a territory and you have a field force that is effective at creating intent and blind to whether intent becomes treatment. We call the gap value leakage, and the field sits closer to it than any other function.

What effectiveness means when the script is just the beginning

A field force is effective when the physicians it serves get more of their patients onto appropriate therapy, faster, and keep them there. That definition changes three things at once.

It changes the rep's job. In a specialty category the physician already knows your efficacy story. What she does not know is which of her patients are stuck in your hub, which payer changed its policy last month, and who at your company can fix it. A rep who can answer those questions is worth a meeting. A rep who delivers the core message a fourth time is not, and the access numbers tell you how physicians are voting.

It changes what you measure. Script to start conversion by territory. Time to therapy. Where patients stall and how long they sit there. Persistence at 90 days. Barrier resolution rate and speed. These are progression measures, and they describe whether the field is converting the intent it creates. Activity measures describe effort. You can have excellent effort and a leaking funnel, and most companies do.

It changes what the field is for. Reps and MSLs encounter access barriers, pharmacy problems and support failures weeks before any dashboard registers them. Right now that signal mostly dies in a call note or a hallway complaint. Captured, classified and acted on, it is the earliest warning system your commercial organization has. The field is one of pharma's most underused intelligence systems, and treating it as a message delivery channel wastes it.

The evidence that experience moves prescribing

This is not a values argument. Bain's pharma practice found in 2018 that around 40% of a physician's drug recommendations relate to overall experience with the company rather than the product, and that physicians who rate a company highly are two to three times more likely to prescribe its products. McKinsey's launch research the same year found fully satisfied prescribers more than twice as likely to prescribe. The field delivers most of that experience. It is the human face of your company at the moment the physician decides whether to trust you with her patient.

The leaders have noticed. Lilly built LillyDirect to remove the burdens patients face in a complex system. Novartis launched a direct platform for Cosentyx because, as its US president put it, the company needs new ways to reach patients "by removing barriers in the system." Novo Nordisk's CEO told Fierce Pharma in January 2026 that the obesity category "acts a lot more as a consumer business than a traditional medication." When the people at the top of the industry describe the job as removing barriers and meeting consumer expectations, a field model that still rewards call volume is out of step with its own leadership.

How to rebuild the field without breaking it

You do not need a new CRM or a reorganization. You need four changes in how the field operates, in this order.

Start with one brand and one leak. Use the commercial data you already have to find where patients stall between script and first dose for a priority brand. That gives the field a specific problem rather than a general exhortation to be more customer centric.

Give the field a way to report what it sees. A rep who learns that a regional payer added a step edit needs somewhere to put that information where it will be classified, assigned to an owner, acted on and measured. Build that loop, even crudely, and run it for a quarter. You will learn more about your access problems than any market research study has told you. We described the operating version in our note on journey operations for field excellence.

Change the scorecard before you change the incentive. Add progression measures alongside activity measures for two quarters so the field can see the connection between what it does and whether patients start. Then move the incentive. Doing it in the other order produces resentment and gaming.

Make the standard explicit. Your physicians compare the experience of working with your company to the best service they got this week. That is the Consumer-Grade standard, and the field is where most of it is delivered. Recognition, anticipation, coherence, effort, resolution and visibility are six conditions you can audit a territory against. A physician who has to tell three people at your company the same patient story has an effort problem you can fix without a single new message.

Three questions for your next field review

  1. For your top brand, what share of prescriptions written in your best territories became treated patients last quarter, and how does that compare with your worst territories?
  2. When a rep learns about a new access barrier, where does that information go, and how long until something changes?
  3. If your most resourceful reps left tomorrow, would patient starts in their territories hold, or do they depend on favors no process replaces?

Field effectiveness used to mean getting in the door. Now it means getting the patient through the door the physician opened. The companies that measure the second thing will have the more valuable field force, whatever their call counts say.

Why healthcare professionals now judge pharmaceutical engagement against the best experiences in their lives, and what that means for the future of commercial leadership. When commercial performance falters, the reflex inside many pharmaceutical organizations is to adjust the machinery of field execution. Leaders revisit call plans, recalibrate targeting models, and increase the volume of activity in the hope that more precision or more frequency will restore momentum. For decades this system has been treated as the central instrument of commercial performance, determining which physicians are prioritized, how frequently representatives engage, and how resources are deployed across territories. Yet the growing gap between commercial effort and commercial impact suggests a deeper issue. T he problem is rarely the design of the call plan itself. It is the context in which healthcare professionals now operate. Physicians are navigating increasingly complex clinical, administrative, and informational environments, and that evolving reality now shapes prescribing behavior far more than the cadence of promotional interactions. What many organizations are experiencing is a widening Customer Context Gap. Commercial systems were designed for a time when prescribing decisions could be influenced primarily through promotional interaction and product information. Today physicians operate inside a far more complex reality shaped by administrative burden, reimbursement constraints, digital information overload, and growing expectations for seamless support across the entire care journey. In this environment the physician’s decision is influenced not only by clinical evidence but also by how easily a therapy fits into the practical realities of care delivery. When commercial models remain anchored in promotional activity while the customer’s context has fundamentally changed, even the most disciplined call plan struggles to deliver the outcomes it was designed to produce. Closing this gap requires a different way of thinking about commercial performance. The question is no longer how to optimize promotional activity but how to align the organization around the real journeys through which physicians help patients receive therapy. Prescribing decisions unfold within complex sequences of clinical evaluation, reimbursement navigation, patient readiness, and ongoing support. When commercial strategy is designed around these journeys rather than isolated interactions, the role of the field force begins to evolve. Representatives are no longer positioned primarily as messengers of information but as partners in removing barriers that slow care. Organizations that recognize this shift begin redesigning their commercial systems accordingly, aligning field engagement, digital support, access programs, and patient services around the same goal: helping healthcare professionals help patients move from clinical intent to successful treatment. From Promotional Activity to Customer Journeys The pharmaceutical industry has historically organized commercial activity around the moment of promotion. Call plans, targeting models, and message sequencing were designed to influence prescribing behavior primarily through informational engagement with healthcare professionals. While this model brought structure and scale to commercial operations, it reflects an earlier era in which the path from clinical awareness to prescribing action was comparatively linear. Today the journey is far more complex. Physicians must navigate an intricate landscape of clinical evidence, treatment guidelines, payer requirements, prior authorization processes, patient affordability concerns, and adherence challenges. Prescribing a therapy is no longer a single decision point. It is the beginning of a chain of events that determines whether a patient ultimately receives and remains on treatment. This is why the commercial conversation must expand beyond the traditional moment of prescription to encompass three interconnected journeys. The first is the Path-to-Prescribe , where scientific evidence, clinical education, and confidence in the therapy shape the physician’s willingness to recommend treatment. The second is the Path-to-Fulfill, where access, affordability, patient readiness, and operational support determine whether that recommendation ultimately becomes therapy in the patient’s hands. The third is the Path-to-Adhere , where ongoing patient support, monitoring, and engagement determine whether patients remain on therapy long enough to realize the intended clinical benefit. Science drives the Path to Prescribe, where evidence, clinical education, and confidence in the therapy shape the physician’s willingness to recommend treatment. Experience shapes the Path to Fulfill, where access, affordability, and patient readiness determine whether that recommendation becomes therapy in the patient’s hands. Sustained outcomes depend on the Path to Adhere, where ongoing support, monitoring, and engagement ensure patients remain on therapy long enough to realize its intended clinical benefit. When commercial organizations focus almost exclusively on the first while leaving the latter journeys fragmented and burdened, a significant portion of therapeutic value is lost between intention and impact. In many therapeutic areas, the result appears in the persistent gap between prescriptions written, prescriptions filled, and therapies sustained—gaps that reflect not a failure of science but a failure of system design. Recognizing these three journeys shifts the unit of focus from promotional activity to the real-world pathways through which care is delivered. It reframes the role of the field force, the purpose of digital engagement, and the design of patient support programs around a single objective: reducing the friction that stands between clinical intent, treatment initiation, and sustained patient outcomes. Customer Context Is the New Commercial Variable For much of the pharmaceutical industry’s history, commercial performance was largely explained by a familiar set of variables. Product efficacy, clinical differentiation, promotional reach, and sales force execution determined the trajectory of most brands. When performance lagged, leaders adjusted those levers by refining segmentation, optimizing targeting, and recalibrating call plans. Today those traditional levers still matter, but they no longer explain commercial outcomes on their own. A far more powerful variable has entered the equation: customer context. HCPs now operate within an environment defined not only by clinical complexity and administrative burden but also by rising expectations shaped by their experiences outside healthcare. Physicians are also consumers. In their personal lives they interact daily with companies such as Apple, Amazon, Tesla, and Netflix that anticipate their needs, remove friction, and simplify complex processes through thoughtful design. These experiences quietly reset the benchmark for competence, responsiveness, and respect for their time. When those same physicians step into their clinical roles, they do not shed those expectations. They carry them with them. The contrast between the seamless orchestration of their consumer experiences and the fragmented systems surrounding many healthcare interactions becomes difficult to ignore. What once felt acceptable now feels unnecessarily burdensome. This dynamic represents the Consumer-Grade Imperative. Healthcare professionals increasingly evaluate pharmaceutical engagement not against other pharmaceutical companies but against the best experiences they encounter anywhere in their lives. In this environment even a clinically superior therapy can struggle if the surrounding system makes it difficult to initiate treatment, navigate reimbursement, or support patient adherence. Customer context therefore becomes the new commercial variable. It determines whether scientific differentiation translates into practical adoption. It shapes whether prescribing intent becomes therapy initiation and whether therapy initiation becomes sustained patient outcomes. Call plans were designed to manage activity. Customer context requires organizations to manage journeys. The Field Force in the Era of Customer Context Recognizing customer context as the defining commercial variable inevitably reshapes how the role of the field force is understood. For decades the pharmaceutical sales representative has been positioned primarily as the carrier of scientific information. Call plans optimized the frequency and sequencing of these interactions to ensure that physicians received consistent messaging. That role does not disappear, but the environment surrounding it has changed profoundly. Physicians today are navigating administrative burden, payer complexity, digital information overload, and increasing time pressure. In this environment they are not simply seeking more information. They are seeking clarity, simplicity, and support that helps them navigate the complexity surrounding treatment decisions. This shift transforms the representative from a messenger of information into something far more valuable: a partner in removing friction from the care journey. Conversations move beyond repeating clinical claims toward understanding the practical barriers that physicians and their teams face as they attempt to initiate and sustain therapy for patients. The most effective field forces are therefore supported by commercial systems designed around journeys rather than activities. Representatives are equipped not only with scientific messaging but with the insight and coordination required to address obstacles across prescribing, reimbursement, and patient support. Field engagement becomes a catalyst for problem solving rather than simply a vehicle for promotion. From Call Plans to Customer-Aligned Commercial Systems If customer context has become the defining commercial variable, then the systems designed to support the field must evolve accordingly. The traditional call plan was built to manage activity. It provided structure for how frequently physicians were engaged, how territories were covered, and how resources were deployed. Yet activity alone does not determine whether therapies ultimately reach patients. What determines impact is whether the commercial system surrounding the physician reduces or increases the burden of delivering care. A customer-aligned commercial system begins with the journeys through which physicians help patients move from diagnosis to treatment and beyond. Marketing clarifies the scientific story. Sales provides trusted relationships and real-time understanding of physician needs. Access teams simplify reimbursement pathways. Patient support programs reduce administrative burden. Digital engagement reinforces and extends human interaction. The result is a commercial system that operates less like disconnected functions and more like an integrated network designed to help physicians help patients. This is the essence of Customer Excellence. It aligns the entire commercial enterprise around the real-world context in which care is delivered. The problem was never the call plan. The problem was the context. Key Takeaways Commercial performance in pharma organizations has traditionally been managed through field execution mechanics, yet the effectiveness of those mechanics increasingly depends on how well they reflect the real-world context in which physicians operate. Customer context has become the most pivotal commercial variable as administrative burden, payer complexity, and consumer-grade expectations reshape how prescribing decisions are made. HCPs now evaluate pharmaceutical engagement against the best experiences they encounter anywhere in their lives, raising the standard for clarity, responsiveness, and ease. Optimizing promotional activity alone is no longer sufficient. Commercial success depends on reducing friction across the journeys physicians navigate as they move patients from diagnosis to treatment. Customer Excellence represents the structural response, aligning marketing, sales, access, digital engagement, and patient support around the real journeys of care delivery . Diagnostic Questions to Consider Are we optimizing the activity of our field force, or designing commercial systems that support the real journeys physicians navigate to help patients receive therapy? How well do we understand the administrative, reimbursement, and operational barriers physicians encounter after they decide to prescribe a therapy? Do our commercial systems reduce the burden placed on physicians and their staff , or unintentionally add to the complexity of care delivery? Are we benchmarking our engagement against other pharma companies , or against the best experiences physicians encounter in their lives as consumers? Have our investments in digital platforms simplified the physician’s experience, or multiplied the number of disconnected interactions they must manage? Are we still managing performance through activity metrics alone , or beginning to understand the context that ultimately determines whether therapies reach patients? Closing Reflection The pharma and life sciences industry has spent decades refining the mechanics of field execution. Call plans, segmentation models, and targeting systems brought structure and discipline to commercial organizations. Yet the environment surrounding physicians has evolved far more rapidly than the systems built to support them. Healthcare professionals now operate in a world defined by consumer-grade expectations for clarity, responsiveness, and ease. When the experience of engaging with a pharmaceutical company fails to reflect those expectations, the contrast becomes impossible to ignore. Organizations that recognize this shift will redesign their commercial systems around the realities of modern care delivery. They will move beyond managing activity and toward understanding the context in which physicians help patients receive treatment. In doing so they will close the gap between scientific innovation and real-world impact. Your breakthrough science deserves experiences worthy of it. Together, we turn customer excellence into real-world impact.
