Information technologies usage models during agile systems functioning

Abstract

The article outlines conceptual and derivative formal models that provide means for estimation of operational properties of agile systems operation with regard to the use of information technologies. The estimation is fulfilled analytically through plotting the dependences of predicted values of operational properties against variables and options of solved tasks. To develop this type of models, the use of information technologies during agile systems functioning is analyzed through a technological agile system. General concepts and principles of modeling of information technology use during operation of agile systems are defined. An exemplary modeling of effects of technological informative and related technological non-informative operations of technological agile systems operation is provided. Based on conceptual models of operation of agile systems with regard to information technologies use, set-theoretical models followed by functional models of agile systems operation using information technologies are introduced. The examples of calculated factors of agile system operational properties and information technologies use are given. The obtained results allow to evaluate predicted values of agile systems operational properties and information technologies use; they help to analytically estimate the efficiency of implementation of new information technologies depending on variables and options in solved tasks.
