An organization can hire strong people, improve every function and adopt respected practices, yet still struggle to outperform. A premium service team may add choices that complicate a low-cost operation, while a sales team promises flexibility the delivery model cannot support. The individual improvements are real; the difficulty is that they serve different ways of competing.
Strategic coherence becomes valuable when choices, activities and capabilities make one another more effective at delivering something customers want. A rival may copy one activity without gaining the benefit of the system around it. That possibility is worth investigating, but the system still has to earn its place in the market and change when its customers do.
The limit of isolated excellence
The appeal of a best practice is straightforward: if another organization has a better process, technology or service standard, adopting it seems like progress. Often it is. The mistake is to assume that a collection of individually excellent practices necessarily adds up to a distinctive strategy.
Consider a premium service feature. It might delight some customers. It might also add training, scheduling and operating costs to a business whose position depends on simplicity and low prices. Neither the feature nor the low-cost model is inherently superior. The question is whether the feature strengthens the particular way that business has chosen to compete.
In “What Is Strategy?”, Michael E. Porter distinguishes operational effectiveness, or performing activities better, from a distinctive position built through choices about what to do and what to leave out. Fit among activities can increase their combined value and make partial imitation less effective. Improving an operation remains essential, but it does not settle which customers to serve or how the business intends to serve them differently.
That distinction changes an executive’s question. Instead of asking whether every function matches a benchmark, ask whether an improvement helps other functions deliver the chosen customer promise. An activity that looks ordinary alone may be valuable because it enables several others. A celebrated practice may be costly if it pulls the organization toward a conflicting promise.
How reinforcement could create an advantage
For that reinforcement to matter, leaders need to follow the connection from the choices they make to the result customers receive. Compatibility is the starting point; the harder question is whether compatible choices actually improve one another.
First, choices must be compatible. A target customer, proposition, channel, operating model and investment pattern should point toward a recognizable way of creating value. A low-price promise paired with a complex service model imposes costs that must be funded somewhere. Coherence does not eliminate trade-offs; it makes them visible.
Consider how a simpler offer might make operations easier to standardize, and how more reliable operations could then make that offer more attractive. The value of each activity depends partly on the other. In Competitive Advantage, Porter uses the value chain to examine the activities behind cost and differentiation, including their interrelationships. It gives leaders a way to investigate that dependence rather than judging each function in isolation.
Those relationships can also develop over time. Teams encounter related problems, refine routines and reuse what they learn. At OutcomesLab, we use Capability Compounding to describe work that improves today's result while building the ability to perform the task tomorrow. That benefit depends on retaining useful knowledge and testing whether the capability still serves the strategy. Repeating the same work without learning will not produce it.
Even if all three steps occur, superior performance does not follow automatically. The combination must produce an outcome customers value or an economically useful cost position. And an effective combination may not remain distinctive: rivals could reproduce it, find another route to the same outcome or benefit when customer expectations change. Reinforcement identifies a possible source of advantage, not proof that an advantage exists.
Southwest as a historical illustration
Porter's 1996 discussion of Southwest Airlines makes this distinction concrete. He describes frequent, low-cost, convenient service supported by connected choices about routes, airports, fleet and service. Those choices made more sense together than they would as separate cost-cutting measures. His historical account is useful because it shows how the payoff from an activity can depend on the wider position.
Imagine an established airline with a different service model copying one visible element of that approach. To gain a comparable benefit, it might also have to change schedules, operations, customer expectations and commitments tied to its existing position. Otherwise, the copied practice could add complexity without producing the economics of the wider system. Applied to that hypothetical rival, Porter's example suggests that the difficulty lies in changing complementary choices and accepting their trade-offs, even when the individual practice is easy to understand.
The lesson is not to copy an airline’s choices. It is to identify which activities jointly produce an outcome in your own business—and which attractive additions might weaken those relationships.
Test coherence against the market
An internally consistent system can still serve an unattractive market. Customers may change what they value, substitutes may improve, or industry economics may leave little room for a return. Porter's Competitive Strategy examines industry forces and competitors, providing an external check on the position a business chooses. An activity system deserves investment only if its internal fit supports a viable way to compete.
Individual improvements can nevertheless produce substantial benefits. In “Does Management Matter? Evidence from India,” Nicholas Bloom and coauthors report that a randomized management intervention increased treated textile plants' productivity by 17% in the first year. That finding challenges any blanket dismissal of transferable practices. It shows an operating benefit without establishing that the plants gained a distinctive, enduring competitive position.
Integration can become an end in itself. A business whose advantage rests on a scarce asset may need to protect that asset more urgently than it needs additional connections between activities. In a rapidly changing market, tight integration can also make it costly to revise a position. The practical judgment is which relationships improve the result and which make necessary change harder.
The test is therefore both internal and external. Do the activities reinforce one another? Does that reinforcement improve customer value or economics? Would the benefits still matter if the market changed? A convincing answer to the first question cannot substitute for the other two.
Turn strategy into connected decisions
In “A Playbook for Winning,” A.G. Lafley and Roger L. Martin connect a winning aspiration with where to play, how to win, the required capabilities and the management systems supporting them. This sequence makes a strategy explicit enough to examine. A proposed customer promise can be tested against the capabilities it needs, and those capabilities against the resources and routines available to sustain them.
These choices come together in the proposed OutcomesLab Coherence Map, drawing on Lafley and Martin's framework and Porter's account of activity fit. The map examines three connected questions:
- Choice fit. Name the customer, the outcome they value and the organization’s intended way to deliver it. State what the organization will not do. If leaders cannot identify a meaningful trade-off, the position may be too broad to guide decisions.
- Capability fit. Map the activities and capabilities needed to deliver that outcome, including their dependencies. For each major initiative, ask: If this activity disappeared, which other activities would become less effective? A weak answer may reveal a stand-alone improvement rather than reinforcement.
- Reinforcement over time. Identify what each cycle of work leaves behind: better judgment, reusable tools, more reliable routines or clearer evidence. Ask whether changing customer needs make those gains more valuable—or put the system at risk of obsolescence.
Use the map as a discussion aid rather than a measured score. Its value is in exposing an assumption that a priority list conceals, then directing attention to the customer evidence, cost data or competitor analysis needed to test it.
What leaders should do next
At the next investment review, require a proposed improvement to explain both its customer benefit and the other activities that must change for that benefit to appear. A stronger local metric is insufficient if the initiative weakens the chosen proposition.
Revisit that explanation when a new segment, technology or channel changes the dependencies. The choice may be to redesign the connected system, rather than add another initiative to arrangements that no longer fit.
At OutcomesLab, we call the potential benefit of reinforcing choices the coherence premium. There is no fixed premium to assume. Leaders have to establish which connections improve customer value or economics and whether those benefits remain worth defending. At the next investment review, that is a more demanding question than whether each function has chosen a respected practice.
