Canonical method
Porter’s generic strategies: choosing an advantage and a scope
What must be established
A useful analysis keeps its controls visible.
- 01
Define the industry, the strategic business area and the breadth of the target before naming the strategy.
- 02
Document the mechanism of relative cost or differentiated value with comparable evidence.
- 03
Test the consistency of the activities, the trade-offs accepted and the signals that would invalidate the position.
Decision reference
Make the next choice more explicit.
DECISION SUPPORTED
Does the position aim at a cost advantage or a differentiated value, on a broad or focused scope?
DELIVERABLE TO KEEP
A competitive position note linking scope, advantage sought, activities, evidence, trade-offs and review rule.
NEXT ELEMENT TO EXAMINE
Porter’s five forcesExplore →Set the competitive scope
Focus does not simply mean targeting a small audience. It presupposes a narrow scope whose needs, costs or activities allow a position different from that of the broad market.
- Strategic business area
- Broad or narrow target
- Reference competitors
- Distinct need
Establish the source of the advantage
Cost advantage rests on a lower relative cost at acceptable value. Differentiation rests on a distinctive value able to sustain a relative price or a preference. Both mechanisms must be observable.
- Relative cost
- Distinctive value
- Relative price
- Customer evidence
Control the activity system
A position becomes defensible when the activities reinforce one another and make imitation harder. Trade-offs, incompatibilities and drifts are described before turning a label into a recommendation.
- Key activities
- Mutual reinforcement
- Trade-offs
- Drift signal

Definition
Generic strategies structure a choice of competitive position by the type of advantage sought and the breadth of the market served. The typology must be linked to the economics and to the activity system that make the position credible.
Marketing case
Use Porter’s generic strategies when a team must produce a comparable diagnosis before choosing, deferring or abandoning an option. The method organises the examination; it replaces neither the human decision nor the evidence specific to the market studied.
Decision question
Does the position aim at a cost advantage or a differentiated value, on a broad or focused scope?
Why this method
It requires making the criteria, the observations and the areas of uncertainty debatable before the commitment. The priority controls are: Define the industry, the strategic business area and the breadth of the target before naming the strategy. Document the mechanism of relative cost or differentiated value with comparable evidence. Test the consistency of the activities, the trade-offs accepted and the signals that would invalidate the position.
Intuition
The result becomes useful when each ranking or category can be linked to an observation, a convention and a decision consequence. A box, a list or a score remains an assumption as long as this link is not established.
Data required
Build a dated register: decision scope, unit analysed, comparable observations, source, period, ranking convention and missing elements. Separate facts, estimates, opinions and working assumptions.
Formalisation
Before any synthesis, set the units compared, the axes or criteria, the threshold rules and the handling of ambiguous cases. An optional weighting organises the discussion; it does not make the result objectively true.
Procedure
1. Frame the decision and the alternatives. 2. Gather comparable observations. 3. Document each ranking and counter-argument. 4. Translate the result into an option, a renunciation, a threshold and a review date.
Worked example
On a teaching case, fill in the variables for two options over the same horizon, make the ranking explicit and record what would change the conclusion. Example values are not market data and must never be generalised without control.
Assumptions
Make sure the assumptions about the scope, the comparability of the observations, the stability of the categories and the mechanism linking the diagnosis to the option are testable. Any assumption that cannot be tested with the available data must remain flagged as such.
Diagnostics
Check the definitions, periods, units, sources and contradictions. If a data point is missing, too old or not comparable, do not compensate silently: flag it, lower the confidence level and define the collection needed.
Robustness
Counter-test the diagnosis with a competing option, a reasonably different convention or an independent source. If the conclusion tips over, present it as sensitive to the model or the assumption, not as a stable recommendation.
Interpretation
Interpret the result as an aid to comparison. It can reveal a diligence priority, an incompatibility or an option to explore; on its own it does not give an order to invest, divest or launch.
What can be concluded
The sheet makes it possible to formulate a competitive position note linking scope, advantage sought, activities, evidence, trade-offs and review rule.
What cannot be concluded
The typology proves neither lasting advantage nor profitability. A position combining cost and differentiation remains possible only if its economics and its activities are demonstrated.
Marketing decision
Record the option retained, the options discarded, the decisive criteria, the insufficient evidence and the decision-maker. A useful conclusion also describes what should be observed before reinforcing or reversing the choice.
When to use or avoid
Use the method when the units to compare and the decision are explicit. Avoid it when the scope is undefined, the data is not comparable, or when a causal conclusion, a quantified forecast or a detailed operational decision is requested without a suitable protocol.
Reproducibility
This sheet describes a reasoning protocol, not a universal result. To reproduce an analysis, keep the register of inputs, the sources, the dates, the conventions, the transformations, the rankings and the version of the deliverable. Without these artefacts, the result is only illustrative.
Level of evidence and sources
Maximum level declared: E1 for documented definitions and sources; E0 for the decision grids proposed by the sheet. 2 sources are displayed below. No causal or predictive conclusion is claimed.
