What this tool does
CM8-224 turns the familiar SWOT grid — strengths, weaknesses, opportunities and threats — into a working register. Each factor is a row with a quadrant, an impact score, a likelihood or confidence score, the evidence behind it, a response action, an owner and a review date. The tool multiplies impact by likelihood to rank the factors, draws the four-bar quadrant profile, builds the TOWS pairing table that turns the grid into a plan, and prints the whole thing as a report you can take into a strategy day or a board meeting.
Everything runs inside this single file in your browser. There is no account, no upload and no network request, so a candid assessment of your own weaknesses never leaves the machine it was typed on — which is the only condition under which people write candid assessments.
Internal versus external — the definition most templates get wrong
The two axes of a SWOT are not "good versus bad". They are internal versus external, and mixing them up is the single most common way the exercise goes wrong.
- Strengths and weaknesses are internal. They are facts about your organisation today — capabilities, assets, dependencies, gaps. You control them, at least in principle. "Our lead times are twice the sector norm" is a weakness even in a booming market.
- Opportunities and threats are external. They are facts about the world — markets, competitors, regulation, technology, input costs. They would exist whether or not your business did. A competitor's new plant is a threat; your under-invested machinery is a weakness. They are related, but they are not the same entry.
The test: if you could fix it with your own money and management attention, it is internal. If it would still be there after you fixed everything inside the building, it is external. The tool shows an Internal/External column on every row so a misplaced factor is visible at a glance, and the balance tile warns you when one whole axis is empty — a SWOT with no external factors is a self-review, and one with no internal factors is a market report. Neither is a strategy input on its own.
Writing factors that earn their place
The value of a SWOT is decided at the writing stage, not the scoring stage. Vague entries produce a grid that everyone nods at and nobody acts on. Compare:
- "Good team" — unarguable, unactionable, and it will read exactly the same next year whatever happens.
- "Three toolmakers with 20+ years each, no succession plan" — specific, checkable, and it points directly at two actions: exploit the capability and close the succession gap.
Three habits produce usable factors:
- One factor per row. "Ageing machines and skills shortage" is two factors with two different owners and two different fixes. Split them.
- Make it falsifiable. If nobody could produce evidence against it, it is a mood, not a factor. The evidence field is deliberately prominent, and the tool insists on at least one line of evidence before it will accept a factor scored at impact 5 — if it is critical, somebody should be able to say why they believe it.
- Name the mechanism. Not "competition increasing" but "competitor opening a plant in the region". The sharper the mechanism, the easier the response is to design.
How the scoring works
Every factor carries two 1–5 judgements, and the score is simply their product:
Score = impact × likelihood (each 1–5, so the score runs 1–25)
Impact asks: if this factor plays out fully, how much does it move the business? 1 is negligible, 5 is critical — existential or transformative.
Likelihood is read differently on each axis, and this is deliberate. For an internal factor it means confidence: how sure are we that this is actually true, at the strength we have described? For an external factor it means probability: how likely is this to materialise within its time horizon? Either way, 5 means near certain and 1 means remote.
Multiplying them keeps the ranking honest in both directions. A catastrophic but remote threat (5 × 1 = 5) sits below a moderate, near-certain one (3 × 4 = 12) — which is usually the right order for management attention. The register colours scores at 16 or above red and 9 or above amber; both thresholds can be moved on the Settings tab, and the band chart uses whatever you set.
Two honesty notes. First, the scores are judgements: 4 × 4 = 16 is not four times as real as 2 × 2 = 4, and small differences between scores mean nothing. Use the ranking to order a conversation, not to settle one. Second, resist scoring everything 4 and 5 — if every factor is critical, the analysis says nothing. A useful discipline is to allow yourself at most two or three factors at impact 5 across the whole grid.
From grid to action — TOWS
A finished SWOT grid is a description. The TOWS step turns it into a plan by pairing each internal side with each external side and asking one question per pairing:
- S–O: which strengths let us seize which opportunities? These are usually the growth moves.
- W–O: which weaknesses would block us from an opportunity we want? These become investment cases — the weakness is worth fixing because of the opportunity.
- S–T: which strengths can blunt which threats? Often the cheapest defence you have.
- W–T: where does a weakness meet a threat head-on? This corner is the risk register — it is where businesses actually get hurt, and it deserves the first hour of any strategy day.
The TOWS table on the Reports tab builds these four pairings from your own rows, showing each side's top-scoring factors so the conversation starts with the biggest items rather than the most recently mentioned ones. Every factor also carries its own response action — exploit for strengths and opportunities, mitigate for weaknesses and threats — with an owner, a review date and a status, so the output of the day is a set of tracked commitments rather than a photograph of a whiteboard.
When to redo the analysis
A SWOT decays. Internal factors change when you act on them; external factors change on their own. As a working rhythm: review the factor list quarterly, re-score it twice a year, and rebuild it from a blank grid whenever something structural shifts — a major customer won or lost, a competitor arriving or leaving, a change in ownership or leadership, new regulation, or a technology that changes your cost base. The review date on each row drives the overdue flags, and the tool will warn you when a review date is more than two years old, because an analysis that old is a historical document.
Signs the current analysis is stale: actions are all marked addressed but the factors read the same; the top scorer has been the top scorer for three cycles with no movement; or the grid contains factors nobody around the table can produce evidence for any more.
Saving and printing
Factors, settings and the report header are written to this browser's local storage as you type, and the toolbar shows the last save time. That storage belongs to one browser on one computer — a different machine, a private window or a site-data clean-up will not have it. Treat Export .json as the real save: one file holding everything, which Import .json restores anywhere. Export CSV gives you the register for spreadsheet work. Reset asks twice, then erases everything — there is no undo.
Print Report produces the full pack from whatever the current filter shows: headline tiles, the four charts, the TOWS view, the response actions and the register. The scope line states any filter in force — clear the filters before issuing anything described as the complete analysis.
FAQ
Can the same thing be both a weakness and a threat? The underlying situation can; the entries should be separate. "60% of revenue from one customer" is the internal weakness; "that customer is consolidating suppliers" is the external threat. Two rows, two scores, two actions.
How many factors should a SWOT have? Enough to be honest, few enough to act on. Eight to sixteen well-evidenced factors beat forty vague ones. If the workshop produced forty, score them all, then let the ranking cut the list before the actions are assigned.
What does "accepted" mean as a status? A deliberate decision to live with a factor and take no action — usually because the cost of acting exceeds the exposure. It is a legitimate outcome for a low scorer; it is a decision that should be minuted for a high one.
Should opportunities really be scored on likelihood? Yes — an opportunity you are unlikely to be able to take is worth less management attention than a smaller one you can bank. If the likelihood only becomes real once a weakness is fixed, that is exactly what the W–O pairing is for.
Who should be in the room? More than the leadership team. The people closest to customers, machines and suppliers hold most of the evidence, and a SWOT written only at the top tends to overstate strengths and understate weaknesses.
Accuracy & disclaimer
This tool structures a management judgement; it does not validate one. The scores are what you entered, multiplied — they are not measurements, and the tool has no knowledge of your market, competitors, finances or customers against which to check them. A confidently scored grid built on weak evidence will look exactly as tidy as a sound one.
Use the output as an input to decisions made by people who understand the business, alongside the numbers — accounts, pipeline, order book — that a SWOT deliberately summarises rather than contains. It is an analysis aid, not advice of any kind.
