The ADL Matrix from Arthur D. Little is a portfolio management method.

The ADL portfolio management approach uses an industry assessment and a business strength assessment as its dimensions. The industry measurement is an identification of the life cycle of the industry. The business strength measure is a categorization of the corporation's SBU's into one of five (six) competitive positions: dominant, strong, favorable, tenable, weak (and non-viable). This yields a matrix of 5 competitive positions by 4 life cycle stages. Positioning in the matrix identifies a general strategy.

In the ADL Matrix approach, the strategist must identify discrete businesses by finding commonalities among products and business lines using the following criteria as guidelines:

  • Common rivals

  • Prices

  • Customers

  • Quality/Style

  • Substitutability

  • Divestment or liquidation

Assessing the Industry Life Cycle stage in the ADL Matrix

The assessment of the Industry Life Cycle stage of each company is made on the basis of:

  • Business market share,

  • Investment, and

  • Profitability and cash flow.

Assessing the competitive position in the ADL Matrix

The competitive position of a firm is based on an assessment of the following criteria:

  • Dominant. Rare, often the result from a almost-monopoly or protected leadership.

  • Strong. A strong company can follow a strategy without too much consideration of moves by rival companies.

  • Favorable. Industry is fragmented. No clear leader among stronger rivals.

  • Tenable. The company has a niche, either geographical or defined by the product.

  • Weak. Business is too small to be profitable or survive over the long term. Critical weaknesses.


Some known limitations of the ADL Matrix are:

  • There is no standard life cycle length.

  • Determining the current industry life cycle phase is difficult.

  • Competitors may influence the length of the life cycle.
