Abstract
Introduces the Fuzzy Industry Maturity Grid as an extension of the Industry Maturity Grid for diagnosing an industry, to identify fast‐growing sectors and to map out growth strategies for sectors showing signs of maturity. By incorporating fuzzy set theory and aggregation models in decision making, the conventional Industry Maturity Grid is enhanced from a qualitative analysis to a semi‐quantitative method which captures an expert′s knowledge of the industry, inclusive of his judgement. It does this via using a linguistic scale describing the characteristics under each of the three main dimensions of the IMG to form fuzzy sets; a hierarchical aggregation of information based on fuzzy aggregation operators; and a conceptual cube to determine the rank and ranking size of the prescribed strategies. Illustrates the application of the Fuzzy Industry Maturity Grid with an example on the Singapore banking industry.
