Abstract

The paper is devoted to the IT-projects dynamics analysis in order to develop
 management processes that assure stability of the projects to scope
 changes. Software development lifecycle is considered combined with one
 of organizational changes which are carried out by IT-projects execution.
 This integral study of IT-projects organizational structure allows to discover
 projects particularities that lead to destabilization and especially "scope
 creep" as a main factor of loss of stability and, as a result, failure of objectives
 realization. To provide required level the model integrity IT-projects are
 to be considered in context of organization´s project portfolio as a part of
 business transformation program. The program in turn is studied not in its
 entire scope but particularly in its part relative to IT-project implementation
 together with obtaining desired results of its product utilization. To secure
 metrics-based project objectives achievement control an EVM modification
 for IT-projects management is presented in the article. Simulation that is
 also performed in the study illustrates internal causes of scope creep problem
 and its solution with methods developed in this study and thus project
 stability assurance.
