The growth–share matrix [2] (also known as the product portfolio matrix, [3] Boston Box, BCG-matrix, Boston matrix, Boston Consulting Group portfolio analysis and portfolio diagram) is a matrix used to help corporations to analyze their business units, that is, their product lines.
After its well-known growth-share matrix, the Boston Consulting Group developed another, much less widely reported, matrix which approached the economies of scale decision rather more directly. This is known as their Advantage Matrix. The matrix was published in a 1981 Perspective titled "Strategy in the 1980s" by Richard Lochridge. [1]
Like in BCG analysis, a two-dimensional portfolio matrix is created. However, with the GE model the dimensions are multi factorial. However, with the GE model the dimensions are multi factorial. One dimension comprises nine industry attractiveness measures; the other comprises twelve internal business strength measures.
Business mathematics comprises mathematics credits taken at an undergraduate level by business students.The course [3] is often organized around the various business sub-disciplines, including the above applications, and usually includes a separate module on interest calculations; the mathematics itself comprises mainly algebraic techniques.

The concept of productive matrix was developed by the economist Wassily Leontief (Nobel Prize in Economics in 1973) in order to model and analyze the relations between the different sectors of an economy. [1] The interdependency linkages between the latter can be examined by the input-output model with empirical data.
An example of experience curve effects: Swanson's law states that solar module prices have dropped about 20% for each doubling of installed capacity. [1] [2]In industry, models of the learning or experience curve effect express the relationship between experience producing a good and the efficiency of that production, specifically, efficiency gains that follow investment in the effort.
In mathematics, every analytic function can be used for defining a matrix function that maps square matrices with complex entries to square matrices of the same size. This is used for defining the exponential of a matrix , which is involved in the closed-form solution of systems of linear differential equations .
In economics a trade-off is expressed in terms of the opportunity cost of a particular choice, which is the loss of the most preferred alternative given up. [2] A tradeoff, then, involves a sacrifice that must be made to obtain a certain product, service, or experience, rather than others that could be made or obtained using the same required resources.
