Decomposition is the basis of works dedicated to business process modelling at the stage of information and management systems analysis and design. The article shows that the business process decomposition can be represented as a Galton Watson branching stochastic process. This representation allows estimating the decomposition tree depth and the total amount of its elements, as well as explaining the empirical requirement for the business function decomposition (not more than 7 elements). The problem is deemed relevant as the obtained results allow objectively estimating the labor input in business process modelling.
