Through the Purpose Lens: Why clarity of purpose matters when pressure builds

 Why clarity of purpose matters when pressure builds 

Last month, I introduced the 5 Lenses which is the framework I use when navigating organisational change. Complex change cannot be understood from a single perspective. The 5 Lenses are not another model to remember. They are five ways of looking at the same problem so that boards and leaders can slow down, see more of the system, and make better decisions under pressure.

This month, I focus on the first lens: Purpose. Not because it is more important than the others, but because when purpose is weak or assumed, every other lens becomes distorted.

Most organisations do not lack purpose. What they often lack is the ability to use that purpose when pressure builds. That gap is where good intentions quietly turn into unsustainable systems.

 

 Purpose is not the same as a mission statement 

When I ask boards and senior leaders about purpose, I rarely get blank looks. Most can articulate a mission or organisational objective clearly and with conviction.

The harder question is this: how does that purpose guide decisions when you have to choose?

In many organisations, the importance of the work quietly becomes the reason an unsustainable pace feels unavoidable. "The work matters" starts to justify patterns of chronic overload that nobody would design intentionally.

Purpose is not what you say. It is what you protect, prioritise, and stop when resources tighten.

Often organisations experience what looks like strong commitment but is actually purpose erosion. Where mission justifies unsustainable pace, or decisions that quietly undermine the very outcomes the organisation exists to serve.

 

 What research helps us see more clearly 

Organisational identity research by Stuart Albert and David Whetten established that purpose comprises what is central, distinctive, and enduring about an organisation, the answer to "who are we?" that shapes real decisions (Albert & Whetten, 1985).

Subsequent research on mission drift shows that drift rarely comes from abandoning values. It comes from incremental adaptations to funding models, regulation, and performance demands (Cornforth, 2014).

What is less often examined is how this erosion happens day to day. Karl Weick's work on sensemaking shows that under uncertainty, people construct plausible stories that allow them to act (Weick, 1995). Purpose provides the anchor for those stories. 

When it is unclear how purpose applies, people default to habit, precedent, or local incentives. These defaults accumulate into culture - and when different parts of the organisation default differently, you get subcultures that can pull in conflicting directions.

That is how organisations with strong missions still make decisions that feel misaligned.

 

 Pressure does not remove purpose - it changes how decisions are made 

There is robust evidence from neuroscience and behavioural research that sustained, unrecovered stress alters how people make decisions. Under chronic pressure, individuals shift from goal-directed decision-making, aligned with purpose, towards habitual responses, repeating what worked before regardless of current context. Working memory, attentional flexibility, and the ability to weigh long-term value against immediate demands all become impaired (Girotti et al., 2018; Soares et al., 2012).

This is not just a wellbeing argument. It is a governance and decision-quality issue.

When organisational rhythms assume constant capacity, with no space to pause, stop, or recover, leaders and teams lose the cognitive conditions needed to apply purpose thoughtfully. Decisions become faster, narrower, and more reactive. Purpose does not disappear, but it becomes harder to use.

Here's one current example of how this shows up: grant-making organisations under pressure to adopt AI tools to triage applications more quickly. The funding case is often framed as "we can reach more people, faster". But when there is no time to test how those tools affect who is filtered out, or to check for bias against smaller or less digitally fluent applicants, the operating rhythm is quietly asking people to trade off fairness and reach without ever naming the choice. The purpose language stays the same. The decision rules do not.

If the operating model makes it difficult for people to exercise judgement, purpose will inevitably erode under pressure, however clearly it is stated.

 

 Purpose breaks down differently at different levels 

One reason this is so hard to spot is that purpose looks different depending on where you sit.

  • At board level, purpose often appears as strategic positioning: why the organisation exists and how it remains relevant. The risk here is not lack of clarity, but insufficient challenge about sustainability. What must stop, slow, or change to make those priorities deliverable?
  • At executive level, purpose becomes the rationale for change: why this transformation, why now. The risk is designing delivery plans that assume continuous stretch without recognising the cumulative load being placed on the system.
  • At operational level, purpose becomes a daily decision filter: what gets time, attention, and care. The risk is that people closest to delivery carry the tension between demand and capacity, without the authority to reset pace or priorities.

These are not communication failures. They are structural misalignments in how purpose is translated into action. When these perspectives drift apart, purpose feels strong in the boardroom and fragile at the frontline. The language stays aligned. The lived experience does not.

When purpose is unclear or unsupported, power fills the gap, often through urgency, hierarchy, or inherited priorities rather than deliberate choice.

 

 Subtraction is a discipline of purpose, not a sign of retreat 

Most transformation efforts focus on addition. New initiatives, new tools, new expectations layered onto existing work. But purpose coherence depends just as much on what an organisation chooses to stop. This is not about efficiency for its own sake. It is about stewardship.

A simple diagnostic for any work currently underway:

  1. Who decided this work started, and for what purpose?
  2. Who benefits from it continuing?
  3. What would genuinely break if it stopped?

If the answers reveal work sustained by habit, fear, or legacy rather than purpose, stopping it is not failure. It is a purposeful act.

Boards and leaders who cannot stop work may not be purpose-led. They may be priority-constrained.

 

 Using the Purpose lens in practice 

Using the Purpose lens means asking, at every stage of change: does this choice protect and express the core reason we exist, especially when it costs us something?

If you want purpose to guide decisions under pressure, not just frame strategy documents, these questions matter:

  • When priorities are agreed, do we also name what will stop or slow as a result?
  • Can people at different levels explain why this change matters in similar language, not identical words?
  • When choices are hard, does purpose guide you or does urgency take over?
  • Does the operating rhythm allow space for judgement, or only for delivery?

Purpose that fails under pressure is not necessarily weak. It may not be designed into how decisions get made.

 

 Purpose is the anchor, not the whole system 

Purpose alone will not make change work. It does not resolve power, fix broken processes, or build capability. But without purpose clarity, those other efforts pull in different directions. This is why the 5 Lenses must work together.

Next month, I will turn to the People lens - how change reshapes roles, relationships, and the unspoken expectations that hold organisations together.

For now, the invitation is simple and demanding: look not just at what your purpose says, but at whether your organisation is designed in a way that allows people to live it when things get hard.
