THE IDEA
The most powerful decision nobody talks about
Before any analysis, before any intervention, before any strategy is formed, someone draws a boundary. They decide what’s inside the system and what’s outside. What counts as relevant and what doesn’t. Who’s a stakeholder and who isn’t. This decision is usually invisible - treated as obvious, natural, given. It’s none of those things. It’s a choice, and it’s the most consequential choice in the entire process.
Boundary critique is the practice of making that choice visible and questioning it. Who drew this boundary? What did they include? What did they leave out? Whose interests are served by the boundary being here rather than somewhere else? What would we see differently if the boundary were wider, narrower, or drawn from a different starting point?
The reason this matters is that boundaries determine conclusions. Draw the boundary around a factory and pollution is an externality - someone else’s problem. Widen the boundary to include the downstream community and the river, and pollution is a system cost. The “problem” and its “solutions” change entirely depending on where the line is drawn. Boundary critique doesn’t tell you where to draw the line. It insists that you know you’re drawing one, and that you think about what that choice includes and excludes.
IN PRACTICE
The invisible line that shapes everything
A company measures its carbon footprint. Boundary decision: do they include only their own operations (Scope 1), or also their electricity use (Scope 2), or also their entire supply chain and product lifecycle (Scope 3)? The narrower the boundary, the better the number looks. The wider the boundary, the more honest the picture. Every sustainability report is, at its core, a boundary decision about what counts.
A school investigates why students are underperforming. If the boundary is drawn around the classroom, the answers are about teaching quality, curriculum, and resources. If the boundary is widened to include home life, the answers include poverty, housing instability, and parental stress. Widen it further to include policy, and the answers include funding decisions, zoning laws, and social safety nets. The same underperformance has completely different explanations depending on where the boundary sits. And each explanation points to a different intervention.
A team retrospective examines why a project went over budget. If the boundary is drawn around the team, the analysis focuses on estimation, planning, and execution. If the boundary includes the stakeholders who changed the requirements mid-project, the analysis shifts to governance and communication. If the boundary includes the organisational culture that makes saying “no” to scope changes impossible, the analysis shifts again. The team might be “responsible” within one boundary and entirely blameless within another.
WORKING WITH THIS
Making the invisible visible
Before accepting any analysis, ask: where’s the boundary? What’s included? What’s excluded? These aren’t awkward questions - they’re the most important questions you can ask about any systems analysis.
When drawing your own boundaries, be explicit about the choice. State what you’re including and what you’re leaving out, and explain why. This doesn’t mean the boundary is wrong - every analysis needs boundaries, and you can’t include everything. But being explicit about the choice allows others to challenge it, and allows you to revisit it if the analysis produces unsatisfying answers.
The most revealing exercise is to draw the boundary in a different place and see what changes. If widening the boundary changes the conclusion, that’s information. It doesn’t necessarily mean the wider boundary is “right,” but it means the narrower one was concealing something. The goal of boundary critique isn’t to find the perfect boundary - there isn’t one. It’s to understand how the boundary you’ve chosen shapes what you can see.
THE INSIGHT
The line to remember
Every boundary is a choice disguised as a fact. The moment you see the choice, you see what it’s hiding.
RECOGNITION
When this is in play
You need boundary critique when an analysis seems complete but feels like it’s missing something. When different groups reach different conclusions about the same situation - they’re probably drawing different boundaries. When an “external factor” keeps disrupting a plan - that factor might need to be inside the boundary, not outside it. When a solution addresses the problem as defined but creates problems in the excluded area. When someone says “that’s outside our scope” about something that’s clearly affecting the outcome.
