The opportunity/vulnerability matrix (Bain/L.E.K.)

The Opportunity/Vulnerability Matrix, developed by Bain and extended by L.E.K., tests whether a business earns the profitability normally associated with its relative market share.

When to use it

• Compare a business or segment’s result with the norm implied by its industry position and classify unexplained underperformance as opportunity or unexplained outperformance as vulnerability.
• Examine whether a low-share but normally performing business could move to a higher profitability band through a value-creating combination with competitors.
• Challenge the standard BCG assumption that every low-share business is merely a question mark or dog.

Origins

Bain research on relative market share and profitability produced the normative curved band known as the ‘banana’. L.E.K. further developed the portfolio application in the late nineteen-eighties. The model uses exceptions to the usual relationship as a prompt for strategic diagnosis.

What it is

The BCG logic treats relative market share (RMS) as a proxy for cost position and profitability. Bain’s studies found that 80 per cent of observations fell within a relatively narrow normative band.

The Opportunity/Vulnerability Matrix

The remaining 20 per cent require explanation:

• Below the banana: profitability is weaker than share would predict. The business has an opportunity to close the gap through pricing, cost reduction, mix or operating improvement.
• Above the banana: profitability is stronger than share would predict. The result may come from defensible differentiation, but it may also depend on temporary pricing, regulation or an unstable industry structure.

The matrix does not say that every outlier must revert to the band. It asks management to identify the mechanism and judge whether it is sustainable.
