1
Define the industry scope precisely
Before scoring anything, write a one-sentence definition of the industry that specifies product or service category, target customer, and geography. Review it with at least one other stakeholder before proceeding.
π‘ If two team members define the industry differently, your force scores will not be comparable β resolve scope disagreements in step 1, not after the analysis is done.
2
Gather data for each force before scoring
Use industry reports, trade association data, customer interviews, and supplier conversations to collect factual inputs. Assign a score of 1 (low threat) to 5 (high threat) only after reviewing at least two data points per force.
π‘ Score each force independently β do not let your intuition about overall industry attractiveness bias individual scores up or down.
3
Score competitive rivalry
Count direct competitors, note market concentration (top-3 share), check the industry's 3-year revenue CAGR, and assess product differentiation. Enter your score and list the two main drivers.
π‘ A declining-growth industry with undifferentiated products and high fixed costs almost always scores 4 or 5 on rivalry β use those benchmarks to calibrate.
4
Score supplier and buyer power
For supplier power, check how many alternative suppliers exist and estimate your switching cost. For buyer power, identify what percentage of your revenue comes from your top five accounts and how easily they could switch.
π‘ If your top three customers represent more than 40% of revenue, buyer power is high regardless of other factors β mark it 4 or 5.
5
Score new entrant and substitute threats
For new entrants, list every barrier and estimate the minimum capital needed to compete at your scale. For substitutes, list at least three alternatives that fulfill the same customer job-to-be-done, even from adjacent industries.
π‘ Search for venture capital investment in adjacent categories β if VCs are funding companies solving your customer's problem from a different angle, the substitute threat is higher than incumbents typically assume.
6
Complete the force intensity summary
Transfer the five scores to the summary table and calculate the average. Flag any force scoring 4 or 5 as a priority threat. Add an overall industry attractiveness rating: 1β2 average = high attractiveness, 3 = medium, 4β5 = low.
π‘ Compare this analysis to last year's if one exists β a rising score on any single force is an early warning signal even if the average looks stable.
7
Write strategic implications for each high-scoring force
For every force rated 4 or 5, write two to three sentences explaining what specifically drives the score and what that means for your pricing, positioning, or investment decisions.
π‘ Name the specific companies, customers, or suppliers driving each high score β anonymous force descriptions produce generic strategy.
8
Assign action items with owners and deadlines
Convert each implication into at least one concrete action with a named owner, a completion date, and a measurable output. Review these in your next leadership meeting.
π‘ Limit total actions to eight or fewer β more than eight items signals an analysis that has not been prioritized and will be ignored in execution.
