Information system project management (IT-project) is a complex iterative process. An important role for the development of complex IT projects plays records of the development lifecycle (LC). The article presents an analysis of the effectiveness of the work on the creation of IT-projects based on two modified models of the life cycle: cascade and spiral. Analysis of the effectiveness of the management of the IT project was implemented on the basis of simulation. The modeling was carried out on the basis of Any Ljgic tools on the example of development of geoinformation system (GIS). It is shown that it is advisable to design GIS on the basis of a modified spiral LC with splitting of the flow of requirements at the input. The peculiarity of the proposed study is to take into account the requirements in the form of communicative interactions of different types. Under the communicative interactions are understood all the interactions between the subjects of the process of creating an IT-project: verbal and non-verbal, carried out on the basis of CASE-means.

“…The mathematical relationship between the stock and flow is given in Eq. 8, where t o is the initial time, Stock(t o ) represents the stock level at the initial time, s indicates the change in the time variables between the initial time and the current time, and Inflow(s) and Outflow(s) represent the information going into and out of the stock at time s, respectively (Chaker et al, 2015).…”

Project delay has been a phenomenon contending with the construction sector opposing time, cost, and quality. This study develops a model, which is a combination of two mathematical decision-making methods DEMATEL and system dynamics modeling, to investigate the impact of the factors on the entire project schedule. The simulation results reveal the importance of minimizing design error to reduce the project delay at the beginning (or preconstruction stage) of the project. Rework, design changes, and change orders must also be closely monitored during the construction to ensure work productivity and on-time project completion. The results also reveal that experienced designers and the use of updated design technology help reduce design errors, thus enhancing work performance in the long term. As shown in the simulation results, the actual project completion time and magnitude of delay steadily reduce with the project series. This explains the fact that the more the consistency and effectiveness in handling the delay factors as similar projects are performed in turns, the better the project performance in terms of time. Therefore, careful consideration of the delay factors reduces the time lag and delay magnitude in construction projects. Other improvements, such as effective supervision during construction which is a function of experienced supervisors, good project management, and cooperation among key stakeholders, including owners, consultants, and contractors, also assist in reducing the construction delay in the long term.

“…is lacking objective processes for model conceptualization" (p. 253). To address this important deficiency, the proposed dynamic SBSC uses variable weights derived from the total direct-indirect fuzzy DEMATEL matrix obtained in Phase I to ensure a systematic and unbiased recognition of the most important causal links amongst the SBSC variables and the strength of influence they exert on one another (as in Chaker et al, 2015). Thus, in phase II of the design process, the emerging SBSC underscores two keystone Integrated sustainability features: the assessment and forecasting of corporate sustainability impact on the ecosystem (Condition 1); and ad-hoc simulation that supports strategy formulation, gap analysis and strategy reformulation (Condition 3).…”

Purpose The instrumental-normative divide that has historically characterized approaches to societal sustainability has also resulted in a rift between underlying mental models and methods destined to address the issue. This separation makes our understanding and tackling of the present global ecological problems only limited and ineffective. The present work aims to draw on theoretical background to develop a conceptual framework for transitioning to integrated corporate sustainability. Design/methodology/approach Drawing inspiration from Luhmann’s (1995) theory of social systems, we consider the instrumental (hard) and normative (soft) methods (Jackson 2019) for corporate sustainability as “conceptual systems” that derive much of traditional social systems’ attributes. These systems are autopoietic, complexity-reducing and functionally differentiated. Following Luhmann’s philosophical grounding, we suggest that integrating the two systems of hard and soft methods boils down to constraining both systems’ internal complexity by imposing limitations on their operational structures. This translates into a decodification–recodification process whereby new methods emerge as a combination of initially disconnected structures. Findings The proposed conceptual integration framework is applied to the case of the Sustainability Balanced Scorecard (SBSC) which has been recently subject to inconclusive controversy. Our work demonstrates that redesigning the SBSC’s architecture following the presented framework leads to embracing complexity, tensions and conflict all the while offering a systematic approach for properly identifying and quantifying cause–effect relationships. Moreover, the proposed framework scores high in Complexity and Systemicity measures, making it both durable and practically useful. More generally, this work drives home the point that an integrated approach to sustainability management is not only important but also feasible and theoretically durable. Research limitations/implications Theoretically, the present work underscores the contribution of systems theory, and particularly the Luhmannian perspective, to transcending some of the most salient “divides” in approaches to societal sustainability. The decodification–recodification process not only enables integrating two distinct conceptual systems, but it also transforms the divide into an opportunity to gain a fresher perspective on one of the most challenging issues of our time. This process may demand, however, some adjustments as we move across various function systems, which requires solid knowledge and understanding of the underlying “codes” that define the systems subject to integration. Practical implications This work implies that integration of varied and sometimes outwardly opposed function systems can and must be carried out to achieve larger societal impact. With respect to the illustrated case, the emerging dynamic SBSC offers a viable strategic planning platform whereby managers and stakeholders can concurrently define, forecast and adjust the societal strategy that maximizes triple bottom-line indicators and sustainable development impact. Social implications Providing decision and policymakers with integrated sustainability management approaches and instruments will have a direct benefit on enhancing the way systems, and large corporations in particular, treat and deal with nature and human beings. Originality/value We propose that proper integration of multiple function systems, employing integrative, unbiased and structured methodologies, can be decisive in challenging current practices in sustainability management and in providing informed guidance for making the high-stake decisions needed in the transition towards sustainable development of business and society.
