Prosci PCT Model: Why Change Programmes Stall and How to Fix Them

Why It Matters

When a change programme is underdelivering, the instinct is usually to look at individuals. Are people engaging with the training? Are line managers reinforcing the new behaviours? Are communications landing clearly? These are reasonable questions, but they address the wrong level of the problem when the real constraint sits above individual readiness. A passive executive sponsor, a project team that treats people-side activity as optional, or a change management function that was brought in three months too late will all undermine carefully designed individual-level interventions regardless of their quality.

The Prosci PCT Model provides a diagnostic frame that operates above the individual. It prompts programme leaders to ask whether the three structural conditions for sustained change are genuinely in place before concluding that the people are the problem. The payoff is clarity: instead of commissioning another round of communications or training, leaders can identify which structural lever needs attention and act on it directly.

Three questions help identify whether this tool is relevant to your current situation. Are your change initiatives consistently underperforming despite reasonable individual-level engagement? Does ownership of the people side of change feel contested or unclear between project managers, HR, and change leads? Are your executive sponsors visibly committed at programme launch but difficult to locate six months in?

Origin and Underlying Logic

The Project Change Triangle was developed by Prosci, the research-based change management organisation also responsible for the ADKAR model. Where ADKAR addresses the five building blocks of individual change (Awareness, Desire, Knowledge, Ability, and Reinforcement), the PCT Model operates at the programme level. Its purpose is to assess whether the structural conditions for successful change exist across the initiative as a whole, not within any single person.

The model's underlying logic is straightforward. Prosci's research into what distinguishes successful change programmes from unsuccessful ones consistently identified three dimensions that must be present and adequately resourced simultaneously. These are not sequential steps; they are concurrent conditions. Weakness in any single dimension does not create a localised problem. It creates systemic drag across the entire programme, regardless of how strong the other two dimensions are.

The PCT Model sits alongside other programme-level change frameworks, including Kotter's 8-Step Process, Lewin's Change Model (Unfreeze, Change, Refreeze), and McKinsey's 7-S Framework. Each of these examines organisational and structural conditions for change rather than individual readiness. The PCT Model is distinctive in its simplicity and its explicit focus on the three dimensions most likely to be misaligned in a typical project environment.

Structure and Application

The PCT Model takes the form of an equilateral triangle, with each vertex representing one of three critical dimensions. The visual symmetry is deliberate: all three dimensions are equally important, and no single vertex can compensate for weakness in another.

The first vertex is Leadership and Sponsorship. This covers the active, visible commitment of senior leaders to the change. Effective sponsorship is not a launch speech or a name on a project charter; it is sustained participation, decision-making authority exercised on behalf of the programme, and explicit personal communication to the wider organisation that the change is a genuine priority. Sponsorship that appears strong on paper but goes silent after the kick-off is one of the most common root causes of programme failure that the PCT Model surfaces.

The second vertex is Project Management. This encompasses the technical discipline of managing scope, timeline, budget, resources, and risk. A change programme without sound project management loses coherence and momentum quickly. Milestones drift, accountabilities blur, and the change management workstream is left preparing people for a go-live date that keeps moving.

The third vertex is Change Management. This is the structured approach to managing the human dimension of the change: stakeholder engagement, communications, coaching, training, and resistance management. It is the dimension most likely to be underfunded, bolted on late, or confused with internal communications alone.

The model is typically applied at two points. At programme inception, it establishes whether the structural conditions for success are in place before significant work begins. When a programme is underperforming, it identifies which dimension is the primary constraint. The diagnostic is usually run with a small leadership group, each participant scoring the three dimensions independently before a facilitated group discussion surfaces the gaps and disagreements that matter most.

The visual format is a triangle, often accompanied by a simple scoring mechanism that rates each dimension on a defined scale. This produces a profile rather than a single number, helping leaders see specifically where attention is needed rather than treating the programme as uniformly healthy or uniformly troubled.

The most valuable first step you can take with this tool is to score all three dimensions honestly with your core leadership team, before anyone has prepared a slide deck or agreed on a narrative. That single conversation will usually reveal where the real constraint is. The harder question is what to do about it once you know, and that is where the deeper application guidance becomes essential.

FAQ

Q: What is the Prosci PCT Model?

A: The Prosci PCT Model, also called the Project Change Triangle, is a programme-level diagnostic framework developed by Prosci. It evaluates three dimensions of change initiative health: leadership and sponsorship, project management, and change management. It is used to identify which structural condition is undermining a programme's effectiveness, either at inception or when results are falling short of expectations.

Q: How does the PCT Model differ from ADKAR?

A: ADKAR focuses on individual change, assessing whether a specific person has the five building blocks needed to transition successfully (Awareness, Desire, Knowledge, Ability, Reinforcement). The PCT Model operates at the programme level, assessing whether the structural conditions for change success are in place across the initiative as a whole. The two models are designed to complement each other: PCT diagnoses systemic gaps; ADKAR diagnoses individual gaps.

Q: Can I use the PCT Model without the rest of the Prosci methodology?

A: Yes. The PCT Model functions as a standalone diagnostic and does not require familiarity with ADKAR, Prosci's certification programme, or any other proprietary methodology. It is conceptually accessible enough for any programme manager or senior leader to apply using basic self-assessment methods. Pairing it with ADKAR creates a more complete diagnostic picture, but neither model depends on the other to be useful.

Q: Is the PCT Model suitable for smaller projects or teams?

A: The model is designed primarily for programme-level assessment and adds most value when leadership and sponsorship, project management, and change management are genuinely held by different people or functions. For very small initiatives where one or two individuals hold all three roles, the diagnostic is less nuanced. It can be adapted for smaller contexts, but its natural home is a programme of meaningful scale and complexity.

Q: How do I know if the PCT Model is right for my situation?

A: It is most relevant when a change programme is underperforming and the cause is not immediately obvious. If individual-level interventions (communications, training, coaching) have been delivered adequately but results are not following, the PCT Model provides a structured way to examine whether the problem sits higher up, in the structural conditions of the programme itself. It is also valuable at programme inception, to establish whether the foundations are sound before significant work begins.
