Quantitative SWOT analysis is the result of contrasting the internal, controllable aspects of the organization (ie, Strengths and Weaknesses) with the external, uncontrollable situational factors (ie, Opportunities and Threats) and then aggregating the numeric scoring of the potential actions an organization might need to reach its goals and objectives.
Qualitative situational analysis provides a poor method for building consensus. In what Dr. Tufte refers to as ‘flatland’, answers pop out at people, but not consensual answers. Therefore, consider using the following quantitative SWOT analysis, developed by Terrence Metz while attending the Kellogg School of Management at Northwestern University.
Traditionally, SWOT is a narrative method for describing a current situation. Strategic planning, product development, annual planning of projects, and current situation analysis rely on the concept of SWOT. We encourage the following quantitative approach whenever you are faced with prioritizing a complex situation involving hundreds of options.
A SWOT Overview
SWOT analysis (or as we prefer, SW-OT) begins by defining each of the four areas below. Understand the importance of “controllable” because you cannot allow a group to define its weakness as an opportunity for improvement. If they control the factor, label it a weakness, not an opportunity.
- Strengths (what a group controls and does well). For example, strength stimulating questions might include:
- How do you achieve your success currently?
- What do you do better than others?
- Identify what you do that you know works well.
- What do others outside view as your strengths?
- Weaknesses (what a group controls but does not do well). For example, weakness stimulating questions might include:
- What could you improve?
- Identify what you do that you know does not work well.
- What do others outside do poorly that you also do?
- Consider what should you stop doing.
- Opportunities (situations, events, etc., outside control of the group that provide unique opportunities for growth, change, etc.). For example, opportunity stimulating questions might include:
- What are you not doing yet but could easily see yourself doing with the right momentum?
- Identify impending changes on the horizon in political or economic policy that might help.
- Which trends could provide a new opportunity for you?
- Threats (changes or competitive forces outside of control that may adversely impact the group). For example, threat stimulating questions might include:
- What is your competition doing much better than you?
- Identify regulatory issues that could stop or hinder progress.
- Which trends are a real threat to your organization/ project?
Brainstorm each list separately. Then fully define the characteristics or attributes using a consensual method.
Analyze each list (PowerBalls provides an excellent tool for analysis) to prioritize the most important characteristics in each of the four areas. Strive to reduce the total to around six of the most significant factors for each area.
Build a matrix (see illustrations below). Opportunities and Threats on top with Strengths and Weaknesses down the side. Explain the scoring method to the group. Each member gets “9” points (it is an arbitrary number and you may change it if you want more or fewer points). They assign their points based on the impact or leverage that each strength or weakness has relative to each opportunity or threat. The higher the impact, the higher the number. Ensure that they don’t just spread them evenly. Scoring should be based on a business understanding. Collect the scoring. Using a spreadsheet (alumni may download), calculate the final scores for each intersection, each column, each row, and each quadrant.
Participants should think about each cell in a column very carefully, and precisely asking “WHAT can we do to seize this opportunity?” or “WHAT do we need to do to defend against this threat?” They might write their thoughts on a separate sheet of paper and when they have completely analyzed a column, go to the cells that represent the most important thoughts and put the most points in those cells.
Review the scores with the group and highlight the quadrants, rows, and intersections with the highest scores. Summarize from the list and have the group convert the most impactful concepts into a narrative action plan.
Example of Quantitative SWOT Analysis by One Person
A fictitious software company employee looks at its strengths as experience, good people, creative ideas, and product integration. Its weaknesses lean towards newness to market and development time. Opportunities may be realized through integrated products, new market, and external market research data that is available. Threats develop from recession, other large competitors (eg, Microsoft), and hardware manufacturers. The one person may score as follows (scored from 1 to 9, with 9 indicating greatest impact):
Quantitative SWOT Analysis Discussion
The scoring indicates the most important strengths are their product ideas and integration. Additionally, development time represents their most significant weakness. Integrated products and growth of computer capture the most favorable opportunities.
Remember that strengths matter if they help take advantage of an opportunity or fend off a threat. Also, weaknesses matter if they prevent a group from seizing an opportunity or making them vulnerable to threats. Opportunities require some strength for them to be leveraged and therefore, seized. The matix helps to highlight which strengths, weaknesses, opportunities, and threats compel strategies, initiatives, or projects.
Eleven Person Aggregate View Using Quantitative SWOT Analysis
In the following, you will see a real-life example with eleven participants. Note that the moderate strengths and weaknesses had little or no impact on the plan. Participants largely weighted their most significant strengths and weaknesses to develop strategies. Quantitative SW-OT analysis helps focus future efforts – products, projects, strategies, and actions. It takes a few hours to complete, but it is worth the effort when consensus becomes critical.
Again note in the example below that only the most significant strengths and weaknesses have a demonstrable impact on the planning effort. The stuff in the middle, we call lukewarm, has little or no bearing on the planning process. Consistently we have seen that the moderately important strengths and weaknesses have little impact on planning.
