Summary. This paper sets out the core constructs of Behavioural Performance — strengths, energy patterns, task demands, alignment, friction, system design and engagement — and the eight-stage pathway model that connects them. It is a working paper: a conceptual foundation offered for examination, not a validated theory.
Two properties of the person
The field describes a person along two distinct dimensions.
Strengths are what a person reliably does well: the behaviours, judgements and forms of work at which they are demonstrably capable. Energy patterns are their recurring patterns of experienced energy across different kinds of work: the forms of work they are drawn toward, sustain easily and recover from quickly, versus the forms that are costly to sustain regardless of capability.
The distinction matters because the two routinely diverge. Capability without energy produces work that is done well but at accumulating cost — the person can, but it drains them, and over time reliability and engagement erode. Energy without developed capability produces enthusiasm that has not yet become dependable output. The most consequential design information sits in the divergence: work that is both a strength and energising should be protected and expanded; work that is a strength but draining should be structured, bounded or shared; work that is energising but undeveloped is where development effort compounds; and work that is neither is the first candidate to automate, delegate or redesign away.
Two properties of the role
A role is described by its required outcomes — the measurable results it must produce, which are held constant — and its task demands — the actions, decisions, interactions and sustained behaviours that producing those results actually requires. Demands are frequently confused with habits: the way a role is currently performed is one path among several, not a fixed property of the outcome. Separating what the outcome requires from how the role happens to be done today is what creates the design space the field works in.
Alignment and friction
Alignment is the degree to which a role’s demands run on the person’s strengths and energy. Friction is the gap: the places where the current design of the role demands ways of working that cut against their recurring patterns of experienced energy across different kinds of work. Friction is a property of the fit between person and current design — not a deficiency of the person, and not a fixed feature of the role. Its practical significance is that it predicts where performance will be least reliable and engagement most fragile, and therefore where design attention pays.
The person-specific execution system as the unit of design
A person-specific execution system is the combination of behaviours, capabilities, workflows, tools, support structures, decision rules, environmental conditions and feedback mechanisms through which a particular individual produces required outcomes.
Where friction is found, the field’s response is design before demand: change the workflow, the tooling, the prompts, the sequencing, the support or the allocation of work before concluding that the person must simply try harder. The person remains accountable for the outcome; what changes is the path. This is the field’s governing principle — hold the outcome constant, adapt the path — and it distinguishes the approach both from systems that force the person to fit the process and from approaches that lower the standard to fit the person.
The principle does not make every part of the path negotiable. Legal requirements, safety controls, ethical boundaries, evidence requirements and quality thresholds remain fixed alongside the required outcome. Sequencing, prompting, work presentation, communication, decision support, delegation, timing, feedback, tool choice and managerial support may be adapted where the governing constraints permit.
Engagement as an outcome variable
The field treats sustained engagement as a measurable outcome, not an attitude to be exhorted. The working proposition is that engagement is substantially a by-product of alignment: people stay engaged in roles that run on their strengths and energy, and disengage — gradually, then suddenly — from roles that run against them. Because engagement predicts retention, discretionary effort and long-run reliability, a design that achieves the required outcome while eroding engagement has not succeeded; it has borrowed against the future.
The pathway model
Eight connected stages link the result that must be achieved with the person, the role and the evidence used to learn:
- Required Outcomes — define the measurable results the role must achieve. These stay fixed.
- Task Demands — identify the actions, decisions, interactions and sustained behaviours the outcome actually requires.
- Person Supply — describe the person’s current capabilities, tendencies, knowledge, experience, energy patterns and constraints.
- Execution Friction — locate delay, inconsistency, excessive effort or failure risk in the interaction between person, task and system.
- Designed Intervention — deliberately change capability, workflow, tools, support, sequencing, environment or decision rules.
- Execution Behaviour — observe what the person actually does inside the redesigned pathway.
- Performance Evidence — determine whether the required outcome is achieved reliably and to the governing standard.
- Continuous Learning — use the evidence to keep refining the fit between person, role and system.
The model is a design loop, not a one-off diagnosis: stages six through eight exist because every design move is a testable proposition, and the fit between person, role and system changes as all three do.
Evidence standards
The field distinguishes three levels of claim, which require different methods and must not be presented interchangeably: descriptions of a person’s reported strengths and energy; associations between alignment and observed performance or engagement; and causal claims that a specific design change produced a specific improvement. Most early work in the field will operate at the first two levels. The discipline the field asks of itself is linguistic as much as methodological: say which level a claim sits at.
Status and limitations
The constructs in this paper are working definitions and the pathway model is a developing framework. The distinction between strengths and energy, the proposition that engagement follows alignment, and the predicted relationship between friction and reliability are all propositions requiring measurement development and empirical test. This paper’s purpose is to make those propositions precise enough to be examined, challenged and revised.
