Features of methods and models in risk management of IT projects

Abstract

IT projects are carried out in the context of the constant development of rapidly obsolete technologies and the variability of user expectations. Implementation of IT projects is closely related to risks, the nature of which depends on factors such as subject area, technology used, number of involved developers, etc. Risk management (RM) is multivariate, which determines the search for comprehensive solutions to increase the effectiveness of RM in projects. For IT projects, this problem is particularly relevant due to the backlog of knowledge gained from technology development and intangible results that limit the possibilities of initial planning and risk control. The object of the article's research is the RM process of IT projects. The subject of the study is to determine the issue of selecting and using RM methods and models, taking into account the peculiarities of IT projects. Two groups of methodologies are allocated: methodologies-standards and methodologies based on system development lifecycle (SDLC). PMBOK and ISO 21500 are referred to standard methodologies. The classification of project management (PM) methodologies is generalized. PM methodologies based on system life cycles include flexible Scrum methodologies, Kanban and extreme programming, as well as cascading PM methodologies using the critical path method (CPM) and critical chain project management (CCPM) projects. As a result of the analysis of the main characteristics of IT projects, the peculiarities of the application of methods and models in the management of risks of IT projects in comparison with projects in other fields are determined. The received recommendations can be used for decision-making in the management of IT projects when the project goals are achieved through the correct identification, assessment, and risk control..

Processo de transformação ágil em uma empresa brasileira de Telecom

“…Esse tipo de abordagem preza pela eficiência operacional, administração e controle das restrições do escopo, do prazo, do custo e da qualidade, com padrões e documentação abrangente (Boehm, 2002;Shenhar, 2012 (Beck et al,2001;Amaral et al, 2011). Tratase de um processo altamente iterativo e incremental, no qual os membros do time e os demais interessados no projeto trabalham juntos, para entender o domínio do problema, identificar o que precisa ser construído e priorizar as funcionalidades (Babenko et al, 2019 (Amaral et al, 2011;Chin, 2004;Highsmith, 2009;Augustine, 2005).…”

“…Os projetos de Tecnologia da Informação (TI) possuem uma gama de aplicações, incluindo desenvolvimento de software, sistemas de informação e implantação de infraestrutura. Executados em um contexto de desenvolvimento tecnológico, o ambiente de negócios e os requisitos estabelecidos por empresas e usuários desse segmento mudam com frequência e de forma inesperada (Babenko et al 2019;Rahmanian 2014). Tais mudanças contribuem para instabilidade em processos importantes dos projetos, como o gerenciamento do prazo e do custo, com impacto direto no cronograma e no orçamento (Rahmanian, 2014).…”

A new model for study of quality attributes to components based development approach

“…"Code review is a phase in the software development process in which the authors of code, peer reviewers, and perhaps quality assurance (QA) testers get together to review code [3]. "Finding and correcting errors at this stage is relatively inexpensive and tends to reduce the more expensive process of handling, locating, and fixing bugs during later stages of development or after programs are delivered to users" [16]. Reviewers read the code line by line to check for": Code review may be especially productive for identifying security vulnerabilities.…”

“…"However, some authors suggest that quality systems should be split into two categories: technical components (statistical control of processes, the use of benchmarking or the implementation of flexible processes) and social or contextual components (leadership, staff involvement, customer orientation, training and development of staff skills, teamwork, communication, shared vision)" [4]. "The risks to the project are influenced by factors such as the level of novelty for the organization, the complexity of the project, its duration, availability of resources, including highly skilled specialists, etc [16]"…”

Customer Transaction Costs Simulation in E-Commerce

“…At the same time, effective management of e-commerce development, as well as the processes of the economy informatization as a whole, is impossible without a full and comprehensive economic and mathematical research of the whole complex of problems, including, on the one hand, the activities of enterprises in the field of electronic commerce, and, on the other, the use of information technology in enterprises and organizations of all branches of economy [1,[4][5][6][7]. The problem of economic and mathematical modeling of e-commerce processes [8][9][10] is currently one of the most urgent due to the dynamic growth of this economic activity area, both in terms of trading operations and territorial coverage of potential participants in e-commerce. In connection with these circumstances, arises the task of ecommerce processes analysis and economic and mathematical tools development, which can be used to study the complex patterns of interaction in e-commerce and be the basis for the development of effective management mechanisms.…”
