SWOT Analysis
Strengths · Weaknesses · Opportunities · Threats
What Is SWOT Analysis?
- Organizing strengths, weaknesses, opportunities, and threats in four boxes
- Separating internal (S·W) from external (O·T)
- The starting point of strategy
Done properly, SWOT first changes the language of strategy meetings. Statements like “our brand is weak” and “the market is tough,” which used to come out jumbled together, now meet the question: “Is that an internal weakness or an external threat?” The moment you separate what you can control from what you can’t, your response splits too: controllable factors become improvement tasks, and uncontrollable ones become contingency scenarios. Agreeing on which box a given fact belongs in settles half the debate before it starts.
There are rules to follow when filling in the four boxes. Judge strengths and weaknesses relative to competitors, not as absolute points of pride. If a competitor could write down the same item, it is not a strength; it is a baseline requirement of the industry. Opportunities and threats, on the other hand, describe the environment one to three years from now, not today, so they can only be filled in properly by feeding in external analyses such as PEST or Porter’s Five Forces. If 3C is the tool for deciding whom to look at, SWOT is where that observation turns into judgment. Limit each box to three to five items. Once the lists are done, go on to the TOWS step, crossing strengths × opportunities (SO), weaknesses × opportunities (WO), and strengths × threats (ST) to draw out action items. That is what turns analysis into strategy.
The most common failure in practice is a workshop where 300 sticky notes go up on the day and there are zero action items the following week. There are usually two causes. One is filling the boxes with unverifiable phrases like “passionate organizational culture” or “market growth.” An item with no numbers or facts attached can’t be challenged or used in the next meeting. The other is treating the filled-in four boxes as the conclusion. SWOT is not the answer but a sorting table for finding it. Unless you turn it into who does what by when, the slide goes straight into a drawer.

Okgum LeeExpert in corporate analysis, fundraising, and business planningDeveloped in the field of management strategy in the 1960s and 70s, it became the most widely used strategic analysis framework.
Let’s look at a hypothetical case: Company A, a second-tier auto parts supplier with 52 employees and KRW 18 billion (≈ US$13,467,000) in annual revenue. Precision-machined engine components account for 40% of its sales, and two major customers have told it they will cut internal combustion engine orders in half starting in 2027. The CEO decided, “We have to change what we earn our living from within three years,” and scheduled a two-day strategy workshop.
- When the head of strategy planning wrote '30 years of accumulated technology' in the Strengths box, the CEO had it struck out, saying "eight competitors write that exact sentence," and had it rewritten as '0.02% defect rate, automaker quality award three years running'.
- They set a rule that the external boxes could not be filled in without data. The sales director spent two weeks visiting the purchasing teams of four automakers to confirm one finding, “2027 engine parts orders cut by 50%,” which went at the top of the threats box.
- The head of production listed “zero EV parts mass-production experience; KRW 1.2 billion (≈ US$897,800) of available equipment investment capacity” as a weakness, then linked it to “rising new orders for battery housings” in the opportunities box and bundled the two as a WO action item.
- On the afternoon of day two, they built a cross-matrix and reviewed 12 ideas. They kept only one from strengths × opportunities (SO), “enter battery module case prototyping with our precision machining capability,” and moved the rest to a parking lot.
- Nine months later, two battery case prototypes had been approved and KRW 1.4 billion (≈ US$1,047,400) in new revenue (7% of the total) had come in, cutting the company’s dependence on engine parts from 40% to 31%. The CEO set up a standing quarterly meeting to revisit the four boxes.
