SWOT Analysis

SWOT analysis sets internal strengths and weaknesses against external opportunities and threats. It earns its place only when it ends in choices.

The questionGiven what we are good and bad at, and what is changing around us, which moves should we make and which should we avoid?

Strengths, weaknesses, opportunities, threats. The strategy-generating version is called the TOWS matrix.

Matrix · Origin disputed, 1960s

Internal Source External

Strengths What the firm does better than rivals

Weaknesses Where the firm falls short of rivals

Opportunities Outside changes the firm could exploit

Threats Outside changes that could hurt results

Helpful Effect on the objective Harmful

Plain SWOT grid. Each entry sits in one box by where it comes from and whether it helps or hurts the objective.

When to use it

A leadership team needs a shared, one-page view of its position before a planning offsite, and the evidence work has already been done elsewhere.
A business unit is being reviewed and you want each executive's view of strengths and threats on the table before the analysis starts, so you can see where they disagree.
You have finished an industry scan and a capability review and need to bring the two together into a short list of strategic options.
A small organization, such as a nonprofit or a practice, needs a simple, cheap structure for a first strategy conversation.

When to avoid it

The client wants to know how profitable an industry can be. Porter's five forces answers that with more structure.
You need to know whether a capability is a lasting advantage. A strength list will not tell you, and VRIO will.
There is no stated objective. Without one, nobody can say whether a factor helps or hurts, and the lists grow without limit.
The team has no time or appetite to turn the lists into choices. Skip it, because an unprioritized SWOT will sit in the appendix and change nothing.

Overview

SWOT lays out four lists on one page: internal strengths and weaknesses, and external opportunities and threats, all judged against a stated objective. It supports a first conversation about position, and with the TOWS matrix it becomes a way to generate strategy options by crossing the lists.

Used alone, it produces description. The common failure is a long, unweighted inventory that nobody checks and nobody uses afterward, which is what Hill and Westbrook found when they reviewed consultants’ SWOTs in the 1990s. Keep the lists short and evidenced, compare every strength with rivals, keep actions out of the opportunities box, and do not stop until the grid has produced a few ranked choices.

The four lists

Strengths

Internal attributes that help the firm reach the objective and that customers or rivals would recognize. A strength counts only relative to competitors. "Experienced management" is a strength only if rivals lack it.

Weaknesses

Internal attributes that hold the firm back relative to competitors. Teams tend to understate them or phrase them as strengths in disguise. Customer and former-employee interviews surface the honest ones faster than workshops do.

Opportunities

External changes the firm could exploit, such as a regulation that opens a market, a competitor's exit, or a shift in demand. An opportunity is something happening in the world, and the firm's plan to pursue it belongs later.

Threats

External changes that could damage results, such as a new entrant, a substitute technology, or a cost shock. The same event can be a threat to one firm and an opportunity to another, depending on its strengths.

What it is not

A strategy. The four lists describe a position. The strategy comes from crossing them, as the TOWS matrix does, and choosing among the options.
A place for plans. "Expand into Asia" is an action, not an opportunity. The opportunity is the change in the market that would make the expansion worth considering.
An analysis in itself. Hill and Westbrook's 1997 review of SWOTs done by consultants in UK manufacturers found long, general, unverified lists that were almost never used later in the project.

The steps

Fix the objective and the unit

Name the business, the time horizon, and the goal the factors are judged against. A SWOT for the whole group and one for a single product line give different answers.
Gather evidence before the workshop

Pull the external scan, competitor data, customer feedback, and operating metrics first. A workshop without evidence produces opinions about the firm, sorted into four boxes.
Draft and cut the lists

Collect entries, then remove anything without evidence, anything a rival would also claim, and any action phrased as an opportunity. Aim for a handful per box, ranked by importance.
Cross the lists into options

Use the TOWS combinations. Ask which strengths can pursue which opportunities, which strengths can blunt which threats, which weaknesses stop the firm from taking an opportunity, and where a weakness meets a threat. Write each answer as a specific option.
Choose and assign

Rank the options against the objective, pick a few, and give each an owner and a next step. Record the options rejected and why, so the same debate does not return next quarter.

In practice

The board of a regional building-products distributor asked for a SWOT, and the first workshop produced fifty-three entries. The consultant cut the list by asking two questions of each: is there evidence, and would a rival say the same about itself? Eleven survived. The strongest strength was same-day delivery to job sites within a ninety-minute radius, confirmed in contractor interviews. The clearest weakness was a quoting process that took three days. The main opportunity was a surge in small residential renovation work, and the main threat was a national chain opening two branches in the region.

The consultant then crossed the lists. The SO option was a renovation-contractor program built on fast delivery. The WO option was to fix quoting, because small contractors would not wait three days. The ST option was to defend the delivery radius before the chain's branches opened. The board chose the first two and dropped a long-discussed showroom project that none of the eleven entries supported.

What you leave with

A short, evidenced list in each box, ranked by importance.
A set of strategy options written from the TOWS combinations.
The two or three options chosen, each with an owner and a first action.
A record of the factors and options set aside, with the reason.

Failure points

The fifty-item list

Every participant adds entries and nobody removes any. The list looks thorough and cannot be acted on, because nothing is weighted and nothing is checked.

Strengths nobody else would grant

Internal teams rate their own capabilities without comparing them to rivals. Parity items such as "good people" or "strong brand" fill the strengths box and the real weaknesses go unsaid.

Actions in the opportunities box

The team writes what it wants to do instead of what is changing outside. The analysis then confirms the plans already in mind, and the external scan is skipped.

Stopping at the grid

The four boxes are presented as the deliverable. No options are generated, the slide goes into the appendix, and later decisions are made without reference to it.

No objective to judge against

Without a stated goal, a factor can be filed as both a strength and a weakness, and the debate is about classification instead of what to do.

The failures above are usually Framing: the wrong problem was chosen before this framework was applied.

Origin

Nobody can say with confidence who invented SWOT. It is often credited to Albert Humphrey at Stanford Research Institute in the 1960s, but that attribution is poorly documented. A 1965 SRI report by Robert F. Stewart, Otis J. Benepe, and Arnold Mitchell used an acronym, SOFT (satisfactory, opportunities, faults, threats), that split issues by present and future rather than by internal and external. The same year, Learned, Christensen, Andrews, and Guth's Harvard textbook Business Policy: Text and Cases set out the appraisal of opportunities and threats in the environment and strengths and weaknesses in the company, without the acronym or a grid. A 2023 history by Puyt, Lie, and Wilderom argues for the SRI line and calls the Harvard attribution a legend. The acronym was in print by 1972, and early two-by-two versions appeared in the 1970s.

In 1982 Heinz Weihrich published the TOWS matrix in Long Range Planning. It crosses the four lists to produce strategy options: strengths with opportunities (SO), strengths against threats (ST), weaknesses that block opportunities (WO), and weaknesses exposed to threats (WT). SWOT carries no trademark or license.
