Deriving key success factors
How can deriving key success factors support strategic choice or positioning?
Contents
These are Key Success Factors (‘KSFs’). They are what firms need to get right to satisfy the customer purchasing criteria (‘CPCs’) of the previous tool.
Key success factors, or KSFs, are the limited capabilities and conditions a business must get right to satisfy its customer purchasing criteria, or CPCs, and compete sustainably.
When to use it
- Always.
Origins
McKinsey consultant D. Ronald Daniel introduced the managerial idea of success factors in his Harvard Business Review article “Management Information Crisis,” published in nineteen sixty-one. He argued that management information should concentrate on the small number of areas that determine competitive success. John F. Rockart of MIT later developed the critical-success-factor method, emphasising the activity areas in which satisfactory performance is essential to an organisation or manager. The approach here applies that logic to industry competition and customer purchasing criteria.
What it is
“Knowledge comes, but wisdom stays,” wrote Alfred, Lord Tennyson. KSF analysis asks what practical wisdom a firm needs in order to succeed in its industry.
Common KSFs include product or service quality, consistency, availability, range and development capability. Service-related factors may include distribution, sales and marketing effectiveness, customer service and post-sale technical support. Cost-related factors can include location, scale, efficient equipment and disciplined operational processes. The right list is specific to a segment and short enough to guide investment.
How to use it
Use the following sequence for each major business segment:
Convert CPCs into differentiation- and cost-related KSFs.
Assess management and market share as additional KSFs.
Weight the complete set.
Identify any must-have thresholds.
Start by converting customer purchasing criteria into the organisational abilities required to satisfy them. Functionality as a CPC may imply research and development as a KSF. Reliability may require quality control. Delivery to schedule may require spare capacity or manufacturing efficiency. These are differentiation-related factors.
Price needs separate translation. Customers may demand a competitive price, but the corresponding KSF is cost competitiveness. Its drivers can include facility location, materials, operational efficiency, subcontracting, process outsourcing, overhead control, remuneration and information systems.
Scale may also matter. A larger business can spread fixed costs and negotiate volume discounts, lowering cost per unit. Review Weighing economies of scale where that mechanism is material, but avoid counting the same scale benefit under several factors.
Next assess management quality and market share. Ask whether a well-managed business with excellent commercial and operational teams but an average product would outperform a poorly managed competitor with a superb product.

Market share can matter independently of a stated CPC. It may reflect relationship depth, reputation and incumbent advantage. A larger installed base can support repeat business and make acquisition easier, especially where customers face meaningful financial, practical or emotional switching costs. Changing a printer is usually easier than changing an accountant.
Weight the KSFs to show their relative importance. Avoid false precision: a calculated weight of 14.526 per cent does not become more truthful because it has three decimal places. Round to the nearest 5 or 10 per cent where that is sufficient; 14.526 per cent would become 15 per cent.
Weights can be built methodically from customer and expert evidence or estimated as a starting hypothesis. One rough initial distribution is market share 20 per cent, cost factors 30 per cent, and management plus differentiation 50 per cent. Adapt it to the industry and ensure all weights total 100 per cent. Then revisit the weights by segment, since price, quality and service importance can differ substantially among customer groups.
Finally, identify must-have KSFs. A weighted average can hide a threshold failure: without a required ISO classification, professional qualification, essential product feature or cost-changing technology, the firm may be unable to bid, deliver or compete at all. Treat these as gates before calculating overall competitive strength.
Top practical tip
Derive each factor from evidence about how customers choose and how the business must operate to satisfy that choice. Record the causal link from CPC to KSF so the list can be challenged and updated by segment.
Top pitfall
Do not create so many “key” factors that none is truly key. Market share, management, two or three cost factors and five or six differentiation factors should normally produce a workable list of about 10, while must-have gates remain explicit rather than hidden in the average.
