A SWOT analysis is a strategic planning tool that maps four factors on a single grid — Strengths, Weaknesses, Opportunities and Threats — to assess an organisation’s or project’s position. Strengths and weaknesses are internal factors you control; opportunities and threats are external forces in the wider environment. Together they show, at a glance, what is helping and what is harming your objective.
This guide explains what a SWOT analysis is, how to build one in six evidence-based steps, and how to read the SWOT matrix. You will find a generic template, a fully worked example for a real UK company, how to convert a SWOT into strategy using TOWS, and how SWOT differs from PESTLE — with a ready-to-use template and the most common mistakes to avoid.
What is a SWOT analysis?
A SWOT analysis is a structured planning framework that maps four factors affecting an organisation, project, or decision: Strengths, Weaknesses, Opportunities and Threats. The technique is credited to Albert Humphrey and colleagues at the Stanford Research Institute in the 1960s, and it remains one of the most widely taught tools in business, management and marketing modules across UK universities.
The power of SWOT lies in a single 2×2 grid that forces you to separate two dimensions at once. The first dimension is origin: strengths and weaknesses are internal (things your organisation controls, such as its people, brand, processes or finances), while opportunities and threats are external (forces in the wider environment you do not control, such as competitors, regulation or economic trends). The second dimension is impact: strengths and opportunities are helpful to your objective, while weaknesses and threats are harmful. Getting these axes right is the difference between a useful analysis and a vague brainstorm — a recurring marking criterion in business assignments and dissertation situation analyses.
How to do a SWOT analysis in 6 steps
A defensible SWOT is built from evidence, not opinion. Work through these steps in order so that each quadrant is grounded in data you can cite — internal financials and audits for S/W, and external sources such as market reports, regulator publications and competitor filings for O/T.
| Step | What to do | Output |
|---|---|---|
| 1. Set the objective | Define exactly what you are analysing — a company, product launch, a market entry, or a strategy. SWOT is meaningless without a fixed decision in view. | One-sentence scope statement |
| 2. Gather evidence | Collect internal data (financials, performance, audits) and external data (market reports, PESTLE factors, competitor analysis). | Evidence pack with sources |
| 3. List internal factors | Brainstorm strengths and weaknesses relative to competitors — not in absolute terms. | Populated S and W columns |
| 4. List external factors | Identify opportunities and threats from the macro-environment and industry. | Populated O and T columns |
| 5. Prioritise | Rank items by impact and likelihood; cut anything trivial or unsupported. Aim for 3–6 strong points per quadrant. | A focused, ranked matrix |
| 6. Convert to strategy | Cross-reference quadrants (TOWS) to turn the analysis into concrete actions. | Strategic options / recommendations |
Worked example: SWOT analysis of Greggs plc
The matrix below is a realistic, evidence-style SWOT for Greggs, the UK food-on-the-go retailer — the kind of filled-in example you can adapt for a business case study. Notice how every entry is specific and competitor-relative rather than generic: that is precisely what distinguishes a top-band assignment from a list of buzzwords. If you are analysing a company you have chosen yourself, see our business dissertation topics and management dissertation topics for subjects that lend themselves to a strong situation analysis.
Turning a SWOT into strategy with TOWS
A common mistake — and a frequent reason students lose marks — is stopping at the four lists. The matrix is the input, not the conclusion. The TOWS matrix extends SWOT by pairing factors to generate actual strategies, converting description into recommendation. You combine an internal factor with an external one in each of four cells.
| TOWS pairing | Strategy type | Greggs illustration |
|---|---|---|
| Strengths + Opportunities (SO) | Use strengths to seize opportunities | Leverage the efficient supply chain to scale delivery and travel-hub stores |
| Weaknesses + Opportunities (WO) | Fix weaknesses by exploiting opportunities | Use the loyalty app’s data to reduce reliance on volatile town-centre footfall |
| Strengths + Threats (ST) | Use strengths to defend against threats | Reinforce value positioning to win cost-conscious shoppers from rivals |
| Weaknesses + Threats (WT) | Minimise weaknesses and avoid threats | Hedge ingredient costs and diversify menu to offset HFSS and inflation risk |
Each TOWS cell yields a recommendation you can defend in the conclusion of an assignment or the strategy chapter of a project. For longer pieces of work such as a capstone or final-year project, this is where your analysis earns its marks — see our guidance on the capstone project for how situation analysis feeds the wider report.
SWOT vs PESTLE: when to use each
SWOT and PESTLE are complementary, not interchangeable. PESTLE (Political, Economic, Social, Technological, Legal, Environmental) is a purely external macro-environmental scan — it feeds the Opportunities and Threats half of your SWOT. In practice the strongest analyses run a PESTLE first, then use its findings to populate the O and T columns of the SWOT. Read our full guide to PESTLE analysis for the external scan, then bring the output back here.
| Feature | SWOT | PESTLE |
|---|---|---|
| Focus | Internal + external | External (macro) only |
| Dimensions | 4 (S, W, O, T) | 6 (P, E, S, T, L, E) |
| Best for | Overall strategic position of a firm/project | Scanning the broad operating environment |
| Typical sequence | Often built using PESTLE output | Run before SWOT to inform O and T |
| Output | Strategic options (via TOWS) | Environmental risks and trends |
SWOT template and common mistakes
To build your own, draw a 2×2 grid: top-left Strengths, top-right Weaknesses, bottom-left Opportunities, bottom-right Threats (internal on top, external on the bottom; helpful on the left, harmful on the right). Add 3–6 evidenced bullet points per quadrant, then cross-reference with TOWS. Avoid these recurring errors:
- Confusing internal and external — putting a competitor (external threat) under weaknesses, or a market trend under strengths
- Listing one-word labels instead of specific, evidenced statements (‘good brand’ vs ‘strong UK brand recognition, 2,500+ stores’)
- Treating strengths and weaknesses in absolute terms rather than relative to competitors
- Padding each quadrant equally — quality and prioritisation beat a long, unranked list
- Stopping at the four lists and never converting them into TOWS strategies or recommendations
- Using unsupported claims — every factor in an academic SWOT should trace back to a citable source

Frequently Asked Questions
A SWOT analysis is a planning tool that lists four things about an organisation or project on a single grid: its Strengths and Weaknesses (internal factors it controls) and its Opportunities and Threats (external factors in the environment it does not control). It gives you a clear, at-a-glance picture of your strategic position so you can plan what to do next.
First fix your objective (what exactly you are analysing). Then gather internal evidence (financials, performance) and external evidence (market and competitor data). List 3–6 evidenced points for each of Strengths, Weaknesses, Opportunities and Threats, judged relative to competitors. Prioritise the strongest points, then use a TOWS matrix to pair factors and turn them into concrete strategies and recommendations.
Internal factors are things the organisation owns or controls — its people, brand, finances, processes and technology — and they appear as Strengths (helpful) or Weaknesses (harmful). External factors come from the wider environment the organisation cannot control — competitors, regulation, the economy and social trends — and they appear as Opportunities (helpful) or Threats (harmful).
For Greggs plc, a strength is its strong value brand and 2,500+ store estate; a weakness is heavy reliance on the UK market and cost pressure on margins; an opportunity is growth in delivery and plant-based products; and a threat is intense competition plus rising wage and ingredient costs. Good examples are always specific and competitor-relative rather than one-word labels.
SWOT identifies and lists the four sets of factors, but stops at description. TOWS takes those same factors and pairs them — Strengths with Opportunities, Weaknesses with Opportunities, Strengths with Threats, and Weaknesses with Threats — to generate four types of actionable strategy. In short, SWOT is the analysis and TOWS turns it into a plan.
Use both, in sequence. PESTLE scans the external macro-environment across six factors (Political, Economic, Social, Technological, Legal, Environmental) and is ideal for understanding the broad context. SWOT then combines that external view with internal strengths and weaknesses to assess overall position. Best practice is to run a PESTLE first and feed its findings into the Opportunities and Threats columns of your SWOT.
