Information technology of quality improvement planning of process subsets of the spice model

The object of research is the software development process. The subject of the study is models, methods and information technology for planning quality improvement of a subset of processes of the SPICE maturity model. The aim of the work is to implement the developed models, method and technology within the framework of information technology and check its performance on test examples. Research methods: quality engineering of software systems; the theory of utility, on the basis of which the target function of the model is built; the method of options sequential analysis; the decision-making theory and modeling of business processes in the development of decision-making support information technology. Applied models: the SPICE maturity model is formalized, which is presented in the form of a hierarchical system; a model for evaluating the level of possibility of a separate process/subprocess of the SPICE model was synthesized; the quality improvement-planning model of a subset of the SPICE model processes under conditions of limited resources is synthesized. The method of options sequential analysis was applied, which was implemented on the basis of the "Kyiv Broom" algorithm. The obtained results: a technology for solving the given task was developed, which is presented in the form of a sequence of execution of individual business processes using the IDEFO standard; the requirements for software were defined; a data model of the subject area was developed; the toolkit for software development is substantiated; the software architecture was chosen; a diagram of software components placement is presented; the performance of the developed information technology was verified on test examples. The practical significance of the work lies in the fact that the obtained information technology allows the managers of IT companies within the limits of the allocated resources in a certain planning period to build the trajectory of the development of the most significant processes of software, to determine how their level of opportunity will increase in each planning sub-period in order to obtain quality software.
