Competitive Advantage and Strategic Capability for ACCA SBL

Updated 11 October 2026 · Fact-checked

Competitive advantage is what lets an organisation outperform rivals over time. It comes from strategic capability: the resources and competences it holds. Resources must be valuable, rare, hard to copy and well organised to give lasting advantage. In SBL, link capability to the scenario and to performance.

Understand Competitive Advantage and Strategic Capability

Competitive advantage means an organisation does something better, or at lower cost, than its rivals, in a way customers value. It shows up as higher profit, market share or growth than competitors earn. It is not the same as being big or old.

Strategic capability is the ability to perform at the level needed to survive and prosper. It rests on two things. Resources are what the organisation has: physical assets, financial assets, people and intellectual assets such as brands and patents. Competences are how it uses those resources: its activities, processes and skills, for example fast product development or excellent service.

Not every strength gives advantage. Threshold capabilities are the minimum a firm needs just to compete in a market. Rivals have them too, so they earn no advantage. Unique resources and core competences are what set you apart. Prahalad and Hamel described core competences as the collective learning of the organisation. They should give access to many markets, add real value for customers, and be hard for rivals to imitate.

Advantage lasts only if it is hard to copy. Capabilities are harder to imitate when they are rare, when the link between action and result is unclear (causal ambiguity), and when they are built from many linked activities (complexity) or grown over time (path dependency). Also, a competence that helps today can become a rigidity if the market changes.

The link to performance is the point of the topic. Strategy chooses where to compete and how. Capability decides whether the firm can deliver that choice. If strategy needs capabilities the firm lacks, performance falls short. In SBL you use this to explain why a firm succeeds or struggles, and what it should build, buy or protect.

Key rules to remember

Core competence tests (Prahalad and Hamel)
Core competence = gives access to a wide variety of markets + adds significant value for customers + hard for competitors to imitate
Use all three tests. A skill that fails one is a strength, not a core competence.
Resources versus competences
Strategic capability = resources (what you have) + competences (how you use them)
Having resources alone does not give advantage. They must be deployed well.
Threshold versus distinctive capability
Threshold = needed to compete; Distinctive (unique resources, core competences) = needed to outperform
Threshold capabilities can still be critical to survive. They just do not differentiate.
VRIO test for sustained advantage
Valuable, Rare, hard to Imitate, Organised to exploit
Valuable only: parity. Valuable and rare: temporary advantage. All four: sustained advantage.

How to solve Competitive Advantage and Strategic Capability questions

Use this method for any question on competitive advantage or capability. It keeps your answer tied to the scenario and to the requirement.

  1. 1Read the requirement and note the verb: identify, assess, explain, advise. Note who you are writing for.
  2. 2Scan the scenario and list the organisation's resources (tangible, financial, human, intangible) and its activities and skills (competences).
  3. 3Separate threshold capabilities from distinctive ones. Ask what rivals also have.
  4. 4Test the distinctive ones: value to customers, rarity, difficulty of imitation, and whether the firm is organised to exploit them (VRIO or Prahalad and Hamel tests).
  5. 5Judge sustainability. Look for causal ambiguity, complexity, path dependency, and signs of rigidity or decline.
  6. 6Link capability to strategy and performance. Say which strategy the capability supports and which gaps threaten results.
  7. 7Make a recommendation: protect, build, buy in, partner or stop. Justify it with scenario facts.
  8. 8Use the professional tone asked for. Keep points short, with evidence from the case.

Quickest way: Resource, test, link

When to use it: Use when you have about 10 to 15 minutes for a capability or advantage requirement.

  1. Underline 4 to 6 resources and skills in the scenario.
  2. Mark each as threshold or distinctive.
  3. Give each distinctive one a quick VRIO verdict in one line.
  4. Add one sentence linking the best capability to performance or strategy.
  5. Finish with one recommendation. Use short headed paragraphs, each with scenario evidence.

Common mistakes in Competitive Advantage and Strategic Capability

  • Listing resources without saying how they give advantage.

    Students recall the categories and stop at description.

    Fix: For every resource, add why it matters to customers or costs, and whether rivals can copy it.

  • Treating every strength as a core competence.

    The term is used loosely in everyday speech.

    Fix: Apply the three Prahalad and Hamel tests. Call it a core competence only if it passes all three.

  • Confusing resources with competences.

    Both words seem to mean what the firm is good at.

    Fix: Resources are what it has. Competences are how it uses them. Show both and the link.

  • Ignoring threshold capabilities.

    Students focus on what is exciting and unique.

    Fix: Note that missing a threshold capability can threaten survival, even though having it gives no edge.

  • Assuming advantage lasts forever.

    The scenario describes current success.

    Fix: Test sustainability. Look for imitation risk, changing customer needs and rigidity.

  • Giving a theory essay with no scenario application.

    Students want to show knowledge.

    Fix: Keep theory to one line. Spend most marks on evidence from the case and a clear recommendation.

Worked examples

Example 1

A regional bank has a well-known local brand, 120 branches and staff who build long personal relationships with small-business customers. Rival banks have launched similar mobile apps. Assess which of the bank's capabilities are likely to give sustained competitive advantage.

Show the solution
  1. Resources: the brand and the branch network. Competence: relationship skills of staff in serving small businesses.
  2. Mobile app: rivals have launched similar ones. It is a threshold capability, needed to compete but not distinctive.
  3. Brand: valuable to customers as a sign of trust. It is fairly rare at local level and built over years, so it is hard to copy (path dependency).
  4. Branch network: valuable for relationships, but a rival with funds could buy or build branches. It is imitable and costly to run, so weaker as an advantage.
  5. Relationship skills: valuable, rare among apps-led rivals, and hard to imitate because they rest on people and culture (complexity, causal ambiguity). The bank must be organised to use them, for example through training and rewards.
  6. Conclusion: the relationship competence, supported by the brand, is the likely core competence.

Answer: The mobile app is only threshold. The brand and especially the relationship competence give likely sustained advantage because they are valuable, rare and hard to imitate. The bank should protect and develop that competence while keeping its digital offer at parity.

Example 2

Explain how a firm's strategic capability links to its performance, using a company that plans to enter a new overseas market where it has no experience.

Show the solution
  1. State the link: strategy sets where and how to compete. Capability decides whether it can deliver. Performance results from the fit between the two.
  2. Identify the capability needed: local market knowledge, distribution, regulatory know-how and adapted products.
  3. Compare with current capability: the firm has no overseas experience, so there is a gap in distinctive and probably threshold capabilities.
  4. Consider the effect on performance: without the capability, expected sales, margins and reputation may fall short of plan.
  5. Consider whether existing core competences transfer. A strong product development skill may carry over if customers value it in the new market.
  6. Recommend closing the gap: hire local managers, partner or acquire a local firm, or enter in stages to learn.
  7. Warn about the risk that old competences turn into rigidities if applied without adaptation.

Answer: Performance depends on matching strategy to capability. The firm should assess which competences transfer, close the gaps through hiring, alliance or acquisition, and phase entry so that learning builds the capabilities the new market requires.

Exam tips

  • Always tie capability to the scenario. Quote facts from the case rather than repeating definitions.
  • Use VRIO or the Prahalad and Hamel tests as a checklist, but present your conclusions in sentences.
  • Expect this topic to feed into other requirements such as strategic choice, acquisitions and change. Be ready to say which capabilities a strategy needs.
  • Earn professional skills marks by judging which capabilities matter most and by giving a clear, reasoned recommendation.
  • Cover both sides: what gives advantage now and whether it can be sustained.

Competitive Advantage and Strategic Capability: frequently asked questions

What is the difference between resources and competences?

Resources are the assets an organisation has, such as plant, cash, people and brands. Competences are the activities and processes through which it uses them well. Advantage usually comes from the competence, not the resource alone.

What makes a core competence according to Prahalad and Hamel?

It should give access to a wide range of markets, add significant value in the customer's eyes, and be difficult for competitors to imitate. It is usually the collective learning of the organisation, not one person's skill.

What is a threshold capability?

It is a resource or competence needed just to meet customers' minimum requirements and compete in a market. Rivals have it too, so it does not give advantage. Lacking it can still threaten survival.

How do I link strategic capability to performance in the exam?

Say which strategy the organisation follows, which capabilities that strategy needs, and whether the firm has them. Then explain the effect on results, such as margins, growth or customer loyalty, using facts from the scenario.
