Research of the Impact of Changes Based on Extemal Influences in Complex IT Projects

Abstract

The issues related to the development of cloud technologies are considered, in particular, the development and implementation of distributed information systems, which today are the most important decision in the market of information technologies. The reasons for the negative conclusion of most such projects are analyzed, the conclusion is made on the necessity of applying to these processes the technologies of project management that are sufficiently developed and effective at this time. The main tasks of the research and scientific novelty are: the classification of the impacts of the environment of projects, the construction of a conceptual model of information interaction on the basis of impacts, construction and research of a mathematical model for taking into account the impacts on the results of the creation of infocommunication systems. To determine the types of impacts on the system (projects) and determine its reaction, the authors proposed a conceptual model cube of interaction processes This made it possible to apply a method for forecasting the state of projects by the impact of changes based on the effects of the project environment, both internal and external. The analysis is carried out to study the parameters and characteristics of projects for the creation of complex infocommunication products and the main causes of project failures based on the generated classes of influences are identified. A list of top-level dynamic changes has been generated that made it possible to determine the main impacts on all components and participants of project activities.
