The five forces (Porter)
That is the basic premise of Michael Porter’s work. And he went on to describe in detail what the fundamental forces are which drive competitive intensity.

Use this when.
Use the framework to understand an existing industry, test entry into a new one or evaluate the attractiveness of a segment. It expands analysis beyond direct rivals to customers, suppliers, substitutes and potential entrants. Repeat it when technology, regulation, consolidation or a business model shift changes the industry boundary or economics.
Use it whenever assessing the attractiveness, evolution or boundaries of an industry.

Competitive analysis: Porter’s five forces model
- For every force, identify the two or three economic drivers that matter most, the evidence for them and the leading indicator that would show the structure changing.
- Define the industry by product or service, customer need, geography and value chain scope. State the time horizon and gather evidence from customers, suppliers, competitors, financial data and regulation. Then analyse the strength, direction and drivers of each force.
Watch for
- Define the industry carefully and do not turn the framework into a static checklist. A boundary drawn too broadly or narrowly changes every force, while technology, regulation, complementors, and business model change can alter the structure faster than a one time analysis suggests.
The five forces (Porter)
- Analyse each force as a driver of price, cost or investment, and include regulation and other external institutions where they materially alter competition.
- Define the industry and customer need before scoring anything. A boundary that is too narrow hides substitutes; one that is too broad averages away meaningful economics. Analyse current conditions and the direction of change for each force.
- Rivalry among existing competitors
Watch for
- Industry boundaries are analytical choices. A rigid definition can hide substitutes, complements and changing business models, producing a false conclusion.

Use this report to show which programme benefits were realised during a defined period, which expected benefits were delayed or missed, and which new benefits have emerged.

Use this plan to connect programme participants with useful knowledge, subject-matter expertise and the information created across components. Effective knowledge management reduces reinvention and duplicate work, helps people find proven answers quickly and reserves scarce expert attention for problems that genuinely require new thinking.
