Subject research paper is the development of technical systems. The aim is to improve the quality of planning the basic characteristics of technical systems development project. Objective is to analyze the works in the area of risk when planning projects, justified the choice of method of planning the main indicators of the project taking into account the uncertainties and risks, developed and tested method of accounting for risks of interference in the project of development of technical systems on the example of the development of an aircraft engine. Used theoretical methods are: the method of discrete-event simulation for obtaining histograms of cost and time of development of technical systems, the method of calculating the cumulative damage risk events, the model matrix representation as a mathematical device for the presentation and study of interference risks. We obtained the following results. Analysis of existing work and standards in the field of risk management, reviewed the existing information system of risk-based project simulation and variability of the project. On the basis of the detected restriction provides an improved method for the basic parameters of the project planning. The process of identification and the following categories of risk identified: the expectations, cost, appearance of additional work, return. Given the typology of interference risks formalized the concept of additivity, synergy and cannibalization (negative synergy). An information subsystem that preparesinput to project performance simulation taking into account the risks, where the use of the data matrix relationship likelihood of risks and interference effects manifestations of risk events. Developed information subsystem was tested on calculation Show cost and runtime stages of research works on the development of an aircraft engine. Scientific novelty of the results is as follows: improved method of discrete-event simulation account of technical systems development project risks by adding a formalization of interference risks.

In philosophical terms, a key issue of communities of practice (CoPs) can be located within one of the key philosophical debates. The need for CoPs is traceable to the inadequacy in certain contexts of the so-called scientific or problem-solving method, which treats problems as independent of the people engaged on them. Examples of this can be drawn from the management domains of information systems development, project management, planning, and many others. In information systems development, for example, the whole basis of traditional systems analysis and design requires such an approach. In essence, in undertaking problem solving, the world is viewed as though it is made up of hard, tangible objects, which exist independently of human perception and about which knowledge may be accumulated by making the objects themselves the focus of our study. A more human-centered approach would, by contrast, see the world as interpreted through human perceptions: the reason why the problem cannot be solved is precisely because it lacks the objective reality required for problem solving. In taking this perspective, it may or may not be accepted that there exists a real world “out there”, but in any event, the position adopted is that our world can be known only through the perceptions of human participants. This question of objective reality is one with which philosophers have struggled for at least 2,500 years, and an understanding of it is essential to determining the need for, and purpose of, CoPs. The next section therefore discusses some of the philosophical issues relevant to the subjective-objective debate: a search for what, in these terms, it is possible for us to know and how we might know it.

The return that organisations derive from investments in information systems and technology continues to disappoint. While there is a very significant body of literature on the factors that should facilitate a successful outcome from systems development, there is growing concern that these prescriptions are not having their desired effect. In this paper, we argue that the success of a systems development project should be measured in terms of its ability to deliver meaningful benefits, rather than the timely delivery of a technical artefact, and therefore organisations should adopt an explicit and proactive benefits realisation approach when investing in IT. Consequently, we sought to explore those actionable factors that might facilitate the effective realisation of benefits from systems development initiatives. Three organisations were identified that claimed to adopt a proactive approach to benefits realisation, and detailed studies of their systems development practices were conducted. Our analysis found that whilst one organisation had been successful in its adoption of a benefits realisation perspective, the other two had not, and this allowed us to identify those factors that helped to explain this difference in outcomes. In short, this paper makes an important contribution by identifying how a subset of traditional systems success factors might be enhanced, to give them a more explicit benefits realisation orientation. Moreover, it presents a coherent set of principles that can be used for deriving other factors and practices.
