Business fundamentals
Testing a competitive advantage
A competitive advantage must show up in customer choices and operating economics, and survive a serious test of its limits.
01Turn claims into questions
Translate leadership claims into testable customer, pricing or cost outcomes. Every advantage is relative to an alternative and a use case. Separate management statements from independent evidence and unresolved questions. Repetition of the same source is not multiple confirmation.
02Examine customer alternatives
Retention may reflect value, temporary constraints or switching costs. Inspect definitions and cohorts. Integration, training and qualification can protect relationships, but dissatisfied customers may build alternatives. Distinguish customers remaining from customers expanding, and include acquisition failures rather than only showcase wins.
03Identify the source of cost strength
Separate structural purchasing, process and logistics advantages from temporary input prices or under-maintenance. Scale can also add complexity. Efficiency gains may be passed to customers in competitive markets. Ask who captures the saving, not simply whether unit cost declines.
04Follow technology into use
Benchmarks, patents and spending do not alone establish customer value. Assess deployment, reliability and full ownership cost. Distinguish owned technology and domain expertise from sourced models. Iteration, compatibility and personnel resilience help determine whether technical capability can remain commercially useful.
05Test brand and distribution economics
Brand awareness matters only through customer behaviour and sustainable economics. Distribution can increase reach while giving intermediaries pricing or customer power. Separate shipments into channels from final demand and inspect returns, rebates and inventory ownership. Regional expansion requires fresh validation; familiarity in one market does not assure success elsewhere.
06Try to falsify the advantage
Test realistic substitutes, customer insourcing, supply changes and capacity expansion. Trace a loss of retention or pricing into acquisition spending, development funding and cash. Useful downside cases challenge the business mechanism, not a list of unrelated catastrophes. Explicit boundaries make updating possible before deterioration becomes obvious.
07Compare durability with expectations
Competitive strength does not eliminate valuation risk. Evaluate duration and maintenance spending alongside price. IPO histories may be affected by restructuring and changing definitions. Scenarios must not assume permanent leadership and negligible reinvestment simultaneously. Good operations and attractive investment terms are separate conclusions.
08Distinguish two kinds of retention
Similar renewal rates can hide rising discounts or genuine expansion at stable pricing. Review acquisition, use, expansion and renewal separately. Temporary migration barriers differ from durable customer value, and selected success stories do not establish representative evidence.
09Review evidence over time
Track measures suited to the business and preserve explanations, not just outcomes. Stable margins can hide mix shifts; more customers can mean smaller contracts. The task is not to find an invulnerable company, but to understand how its strength is built, maintained and potentially weakened.
