# SPACE Matrix The SPACE matrix places the firm in an aggressive, competitive, conservative, or defensive posture. **The question.** Given our finances, our competitive position, and the strength and stability of our industry, should we attack, compete, consolidate, or defend? Also known as: SPACE stands for Strategic Position and Action Evaluation. ## When to use it - A board is split between expansion and retrenchment and wants a structured first read on stance before specific moves are discussed. - You are working through several business units and want the same four dimensions scored for each, so the debate has a common vocabulary. - A client's financial position and market position point in opposite directions, such as a strong market and a weak balance sheet, and you need to show how that shapes the options. - You are running a workshop or a teaching session where the aim is to make assumptions explicit and argue about them. ## When to avoid it - The decision has money behind it and needs a financial case. The scores are judgments, so use a valuation or scenario work instead. - The people scoring have a stake in the answer and there is nothing independent to score from. The result will drift toward the preferred conclusion. - The issue is a specific choice of segment, price, or position. The strategy clock or a look at customers and competitors is more direct. - The client expects precision. Averages to one decimal place look exact and are not, and the matrix is better treated as a discussion structure. ## Overview SPACE scores a business unit on four dimensions: financial strength, competitive advantage, industry strength, and environmental stability. Two scores are added for each axis, and the point where they land puts the unit in an aggressive, competitive, conservative, or defensive posture. It supports a first conversation about stance, such as whether to expand or consolidate, before anyone chooses specific moves. Everything depends on the scoring, which is judgment. Two sensible people can place the same business in different quadrants, and a point near an axis can switch on one score. It is more common in textbooks and case courses than in client work, and there is little published evidence that following the posture improves results. Use it to expose disagreements about evidence. ## Four dimensions, four postures ### Financial strength Internal. Factors such as return on investment, leverage, liquidity, cash flow, and the capital needed against what is available. Scored from +1 to +6, where higher is stronger. ### Competitive advantage Internal. Factors such as market share, product quality, customer loyalty, and technical know-how. Scored from -1 to -6, where a score closer to zero is stronger. The negative sign is easy to forget, and it is the most common arithmetic error. ### Industry strength External. Factors such as growth potential, profit potential, financial stability, and ease of entry. Scored from +1 to +6, where higher is stronger. ### Environmental stability External. Factors such as technological change, demand variability, inflation, the range of competing prices, and barriers to entry. Scored from -1 to -6, where a score closer to zero is more stable. ### Aggressive Upper right. Strong finances in a strong industry, with a sound competitive position and a reasonably stable environment. There is room to attack, through growth, acquisition, or new markets. ### Competitive Lower right. A strong competitive position in an attractive industry, but weak finances or an unstable environment. The firm can win in the market and may not be able to fund the fight. ### Conservative Upper left. Sound finances and a stable environment, but a weak competitive position or an unattractive industry. The posture favors consolidating around the core and protecting what works. ### Defensive Lower left. Weak finances, an unstable environment, and a poor competitive position. The posture favors cutting back, protecting cash, and exiting what cannot be fixed. ## What it is not - A measurement. The scores are judgments. Two sensible scorers can place the same business in different quadrants, and the result is only as good as the evidence written beside each score. - A portfolio matrix like the growth-share matrix. Those plot units on measured variables. SPACE scores judgments on four dimensions, and the method gives no guidance on how to weight the factors within each one. ## The steps 1. **Choose the unit.** Decide what you are scoring. A company, a business unit, and a product line give different answers, and a diversified firm should have one matrix per unit and not an average of them. Write the unit at the top of the page. 2. **Pick the factors.** Choose four to eight factors for each dimension, the ones that drive results in this market. Define each in a sentence. Generic factors dilute the ones that matter, so remove any that would be true of every firm in the industry. 3. **Score independently, with evidence.** Have several people who know the business score every factor on their own before comparing. Use +1 to +6 for financial strength and industry strength, and -1 to -6 for competitive advantage and environmental stability. Write one line of evidence beside each score, such as a margin or a share figure. Then average each dimension. 4. **Add and plot.** Add competitive advantage to industry strength for the horizontal position, and financial strength to environmental stability for the vertical one. Plot the point and read the quadrant. Note how far the point is from the center. 5. **Argue about the gaps.** Compare scorers. Where two scores differ by two points or more, go back to the evidence. Check how sensitive the point is, because one that sits near an axis can change quadrant on a single score. The disagreements are usually the useful output. 6. **Turn the posture into options.** Write down which kinds of moves the posture favors and which it rules out. Then choose among specific moves with other tools, because the matrix names a stance and does not pick an action. ## The formula Horizontal axis = CA + IS. Vertical axis = FS + ES. Add the average competitive advantage score to the average industry strength score to place the point left or right of center. Add the average financial strength score to the average environmental stability score to place it above or below. - FS: financial strength, the average of its factor scores, from +1 to +6. - CA: competitive advantage, the average of its factor scores, from -1 to -6. - IS: industry strength, the average of its factor scores, from +1 to +6. - ES: environmental stability, the average of its factor scores, from -1 to -6. ## In practice Two partners at a regional wholesale distributor disagreed about whether to buy a smaller rival. The analyst had four managers score the firm independently, with a line of evidence for each score. Financial strength factors scored 3, 1, 2, and 2, an average of 2.0. Competitive advantage scored -3, -2, -2, and -3 on market share, service quality, customer loyalty, and technical know-how, an average of -2.5. Industry strength scored 5, 4, 3, and 4, an average of 4.0, and environmental stability scored -4, -4, -3, and -3, an average of -3.5. The horizontal axis came to -2.5 + 4.0 = 1.5 and the vertical axis to 2.0 + (-3.5) = -1.5, which is the competitive quadrant. The finance director had scored environmental stability at an average of -1.5 on his own. With that score the vertical axis would have been 2.0 + (-1.5) = 0.5, and the firm would have plotted as aggressive. The real argument was about how stable the market was, not about the acquisition, so the team went back to the evidence on demand swings and technology change. ## What you leave with - Scores for each dimension, with a line of evidence behind each factor. - A plotted point and posture for the unit, and a note on how sensitive it is to differences between scorers. - A list of disagreements between scorers, which shows what to research next. - A short statement of which kinds of moves the posture favors and which it rules out, to feed the options work. ## Failure points ### Scores that fit the preferred answer The people with a stake in the decision do the scoring, and the factors they weigh lean toward their conclusion. Averages hide it. Have someone without a stake score separately and compare. ### False precision Averages to one decimal place and a neat plot make the result look measured. A point half a unit from an axis can switch quadrants on one score, and the room treats the quadrant as a finding. ### Equal weights by default Every factor counts the same, even when one factor dominates in the industry. The method gives no guidance on weights, so the choice is made implicitly. State the weights, or drop the weak factors. ### One matrix for a diversified firm A strong unit and a weak unit are averaged into a posture that fits neither. Score each unit separately. ### Stopping at the posture The team agrees it is "competitive" and nothing follows. The matrix names a stance, and the stance still has to be turned into choices about where to invest, what to buy, and what to leave. The failures above are usually [Framing](https://usefulconsultingframeworks.com/your-edge/#framing): the wrong problem was chosen before this framework was applied. ## Origin The matrix is credited to Alan J. Rowe, Richard O. Mason, and Karl E. Dickel, whose textbook Strategic Management and Business Policy: A Methodological Approach was published by Addison-Wesley in 1982. Fred David's strategic management textbooks later made it a standard teaching exercise, and many people meet it there and not in the original. In David's version each posture is paired with a list of generic strategy types. The authors who followed have changed the factor lists freely, so two versions of SPACE can differ in what they score. The method is not trademarked or licensed. ## Further reading - [Strategic Management and Business Policy review (Academy of Management Review)](https://doi.org/10.5465/amr.1983.4287755).
