Growth–share matrix

The growth–share matrix (aka the Product Portfolio Matrix, Boston Box, BCG-matrix, Boston matrix, Boston Consulting Group analysis, portfolio diagram) is a chart that was created by Bruce D. Henderson for the Boston Consulting Group in 1970 to help corporations to analyze their business units, that is, their product lines. This helps the company allocate resources and is used as an analytical tool in brand marketing, product management, strategic management, and portfolio analysis. Some analysis of market performance by firms using its principles has called its usefulness into question.
