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.

The emergence of new forms of business organization due to the development of the latest information technologies leads to the need to find adequate ways to manage virtual structures. This article discusses the features of multi-agent artificial intelligence systems and the possibilities of their application in virtual organizations. The concept of a multi-agent system is proposed, which will improve the management processes of a virtual organization. The developed algorithm is adaptive and can be used in various virtual organizations for self-development of their management systems and achieving their goals.

<p><i>Software Testing is the process of evaluating a software program to ensure that it performs its intended purpose. Software testing verifies the safety, reliability, and correct working of software. The growing need for quality software makes software testing a crucial stage in Software Development Lifecycle. There are many methods of testing software, however, the choice of method to test a given software remains a major problem in software testing. Although, it is often impossible to find all errors in software, employing the right combination of methods will make software testing efficient and successful. Knowing these software testing methods is the key to making the right selection. This paper presents a comprehensive study of software testing methods. An explanation of Testing Categories was presented first, followed by Testing Levels (and their comparison), then Testing Techniques (and their comparison). For each Testing Levels and Testing Techniques, examples of some testing types and their pros and cons were given with a brief explanation of some of the important testing types. Furthermore, a clear and distinguishable explanation of two confused and contradictory terms (Verification and Validation) and how they relate to Software Quality was provided.</i></p>

In the game of Golf, a player is challenged to take the minimum strokes to complete a round of 18 holes under varying playing conditions. Players use different clubs depending on their skill levels to achieve the desired distance while taking shots at the golf ball from the start (tee off) to the hole (pin). Unlike other games which have a standardized playing area, the terrain in a golf course comprises of various natural and manmade features viz. fairways, bunkers, trees, water bodies etc, which increase the difficulty level of the game and keep the players challenged.The game of golf has a fascinating similarity to a software development life cycle. If the holes on a golf course are considered akin to milestones in a development project then most of the Software Engineering models focus on software development in groups. Thus, we propose SOLF i.e Software Development Lifecycle model based on Golf, as a SDLC ideal for individuals or a small group of 2-3 developers. The proposed model is easy to comprehend, flexible and optimally adjustable in a dynamic environment.SOLF divides the project into 18 stages wherein each stage of the project will have 3 to 6 tasks which are required to be completed within a fixed timeline. The stages are managed by creating checklists at the start akin to the pre-shot routines in golf and the customer feedback is received on reaching each of the milestones similar to applause in the game of golf. Terrain of the golf course is reflected as risk list which are varying for each of the stages.SOLF achieves 10x speedup in software development and research projects as it creates an environment of challenges and drives the developer towards self excellence. It also inculcates a spirit of competition and sportsmanship by challenging the developers on various 'terrains' of development.

DevOps is the combination of cultural mindset, practices, and tools that increases a team's ability to release applications and services at high velocity. The development and operations teams always have a conflict around the scope of responsibility. With these differences the quality and speed of delivery across software Development Life Cycle is negatively impacted. DevOps is about removing the barriers between two traditionally delimited teams, development and operations. With DevOps, these two teams work together to optimize both the productivity of developers and the reliability of operations. They strive to communicate frequently, increase efficiencies, and improve the quality of services they provide. They take full ownership for their services, often beyond where their stated roles or titles have traditionally been scoped. Transitioning to DevOps requires a change in culture and mindset first. It is quite difficult to persuade a whole company to change its culture at once. This paper aims to bring different phases of software development lifecycle into DevOps implementation strategy and presents a comprehensive collection of leading tools used across Software Development life Cycle to automate and integrate different stages of software delivery. This paper also highlights on DevOps practices which span across different phases of the Software Development Lifecycle and how those can be implemented with different tools available.

Security inspections are increasingly important for bringing security-relevant aspects into software systems, particularly during the early stages of development. Nowadays, such inspections often do not focus specifically on security. With regard to security, the well-known and approved benefits of inspections are not exploited to their full potential. This book chapter focuses on the Security Goal Indicator Tree application for eliminating existing shortcomings, the training that led to their creation in an industrial project environment, their usage, and their reuse by a team in industry. SGITs are a new approach for modeling and checking security-relevant aspects throughout the entire software development lifecycle. This book chapter describes the modeling of such security goal based trees as part of requirements engineering using the GOAT tool dedicated plug-in and the retrieval of these models during the various phases of the software development lifecycle in a project by means of Software Vulnerability Repository Services (SVRS) created in the European project SHIELDS (SHIELDS - Detecting known security vulnerabilities from within design and development tools).
