The experience curve (BCG)

The experience curve connects accumulated output with the possibility of lower unit cost. It supports a low-cost strategy—and may strengthen a focused position—but only when the organisation captures and protects the learning created by volume.

When to use it

• Consider it whenever market-share growth could produce a sustainable cost advantage.

Origins

Industrial learning curves predate Boston Consulting Group. Early aircraft-production studies found that each doubling of cumulative output could reduce labour time per unit by roughly 10–15 per cent. BCG broadened the observation from labour to the total value-added cost of standard products and connected it to competitive strategy.

The experience curve became an important assumption behind BCG’s Growth/Share Matrix: if accumulated experience lowers cost, relative market share may indicate relative cost position.

What it is

The original learning insight was that repetition improves task performance. Early aviation evidence suggested a 10–15 per cent reduction in labour time after cumulative production doubled.

The experience curve

Cumulative volume

BCG studies across consumer and industrial sectors proposed a broader ‘law of experience’: the unit cost of value added to a standard product commonly falls by a constant percentage—often 20 to 30 per cent—whenever cumulative output doubles.

Important mechanisms include:

• Labour efficiency: workers and managers learn better sequences, shortcuts and problem-solving methods.
• Process efficiency: workflows become standardised, balanced and less wasteful.
• Technology efficiency: automation and improved equipment reduce inputs or increase throughput.
• Design and sourcing: accumulated knowledge can simplify products, improve yields and strengthen purchasing.

BCG’s strategic interpretation was more distinctive than the underlying observation. If cumulative volume creates cost leadership, a company may rationally prioritise share and production before short-term profit, then use lower cost to reduce price, expand volume and reinforce the advantage.

Relative market share and the experience curve effect: an example

How to use it

Identify a segment in which the company already has scale or a credible route to leadership. Estimate the historic relationship between cumulative output and comparable unit cost, separating learning from input-price changes, utilisation, product mix and inflation.

Then model a share-building option. Ask how much additional volume is required for the next doubling, which investments capture the learning, when unit cost would fall and whether savings should support margin or lower price. Test competitor response: rivals may match price, imitate methods, share the same suppliers or introduce a technology that resets the curve.

The effect is strongest when knowledge remains proprietary and the product and process are stable enough for experience to accumulate. It weakens when employees move freely, suppliers spread best practice, outsourcing gives competitors the same economics, customisation prevents repetition or a discontinuity makes old experience irrelevant.

Top practical tip

Invest for share only after demonstrating how additional cumulative volume will translate into a defensible reduction in unit cost.

Top pitfall

Industry experience may be shared. Volume without proprietary learning, disciplined execution or customer demand can destroy value rather than create advantage.
