Project Implementation Decision Using Software Development Life Cycle Models: A Comparative Approach

Software Engineering encompasses a lot of processes of which writing of efficient codes for development of high quality and effective programs is one of them. Development of quality software is achieved through a well-articulated Software Development Life Cycle (SDLC) model. Delivery of software project within timeline and budget require thorough analysis from which these two pertinent questions must be answered such as what shall we do next and how long shall we continue to do it’? Therefore, the need for an appropriate SDLC model for a software project is of high significance. V-Model is applicable in project that requires a lot of time and are complex in nature. When the focus of the project is more of quality than fast delivery time, then V-Model is a choice of SDLC to be considered. Also, Waterfall model is desirable when quality control is of concern with short project duration. On the other hand, Spiral Model is desirable when organizational expectations are unpredictable concerning the software development process. Irrespective of the size of the project, delivery time and level of expertise involved, the organization of the project plays a significant role in the choice of SDLC model. SDLC model under consideration, must take into cognizance the level of risk, duration of the project and cost implication associated with every software project for successful completion. Comparative analysis of the three SDLC models studied was presented.

This history column article provides a tour of the main software development life cycle (SDLC) models. (A lifecycle covers all the stages of software from its inception with requirements definition through to fielding and maintenance.) System development lifecycle models have drawn heavily on software and so the two terms can be used interchangeably in terms of SDLC, especially since software development in this respect encompasses software systems development. Because the merits of selecting and using an SDLC vary according to the environment in which software is developed as well as its application, I discuss three broad categories for consideration when analyzing the relative merits of SDLC models. I consider the waterfall model before the other models because it has had a profound effect on software development, and has additionally influenced many SDLC models prevalent today. Thereafter, I consider some of the mainstream models and finish with a discussion of what the future could hold for SDLC models.

In earlier software development all process is completed and implemented but now this is not a scenario. In modern era changes are frequent to any software product or module which is under development phase, due to market competitions priority of requirement changes Due to the fact that the traditional process models are incompatible with these changes, agile methodology is used instead.. Earlier waterfall model was convenient because of less requirement of features and emergency of the application in the short period of time .This Paper Discusses the comparative Analysis of waterfall model and agile methodologies while agile methodologies are taking over, even the waterfall model is older and time consuming it is still use in many sectors The paper will help other software development process models. Agile method plays important role in the areas of software project management, software schedule management etc. The main aim of the agile is Customer satisfaction as well as faster development with low defect rate. This paper reflects the comparison of the agile processes with waterfall model software development life cycle model. Agile processes aren't always beneficial; they have their own set of downsides. Agile method promotes continuous iteration of development and testing throughout the software developed.

Apart from the different formats of software process descriptions and life cycle models as discussed in the previous chapter, there are many different types of such models. The basis for these models is formed by several fundamental life cycles, in particular sequential models such as the waterfall model or the V-shaped model, and iterative-incremental models such as the spiral model or Scrum. These fundamental life cycles can be varied in many forms, or extended by adding information leading to detailed process models such as the (Rational) Unified Process. The models can also include different sets of processes, where at one end of the spectrum, software processes support software development by structuring the different development-related activities. At the other end of the spectrum, software processes also provide a more comprehensive perspective, e.g. including operation and IT service management, or interfacing with organisational and administrative tasks. Depending on the purpose of the model, there are some very different types of process reference models available, including for example method-driven life cycle models, agile methodologies, process assessment models. In this chapter, we survey these different types of software processes and their role in the software life cycle. We provide a categorization of software processes, introduce the basic life cycle models, and present some selected reference models.

Chapter 12 - The Development Process

This scientific article explores the theoretical aspects of team management in the context of different management methodologies and compares the effectiveness of Agile and Waterfall project management methodologies. The study reveals that Agile methodologies are highly effective and provide significant cost savings but are still not widely used in Ukraine. Also, this article compares such methodologies as Scrum, Kanban, Lean, PRINCE2, SIX SIGMA, and Hybrid. The choice of methodology should depend on specific project conditions, such as team size and project complexity. The study presents new insights into the advantages and disadvantages of various approaches to team management. The study finds that teams using the Agile methodology achieve better results on average than teams using the Waterfall methodology. It also shows that using Agile methodologies is more common in small teams than in large ones. As project complexity increases, traditional methods such as Waterfall become more common. Therefore, the article provides a valuable contribution to the field of project management and can be helpful for project managers who are looking for an optimal approach to managing their teams. Purpose of the article. The purpose of this article is to investigate the theoretical aspects of team management in the context of different management methodologies and to compare the effectiveness of these methodologies in Ukraine and other countries. In addition, the paper aims to contribute to the ongoing debate about the benefits of using agile methodologies in project management and to highlight the need for further research in this area. Design/methodology/approach. This article is based on a comprehensive literature review of recent research and publications on team management and project management methodology. Research sources used include scientific journals, conference proceedings, books and online resources. The focus is on comparing and contrasting different approaches to team management across methodologies including Agile, Waterfall and Lean. The study also includes an analysis of empirical data collected during surveys conducted in Ukraine and other countries to determine the most effective team management practices for projects of various sizes and complexities. The research design used in this study is primarily qualitative as the focus is on exploring the theoretical aspects of team management through different management methodologies. However, research also includes a quantitative element, as the analysis of survey data involves the use of statistical methods to identify relationships between variables. Limitations of the study include the sample size of the survey participants and the geographical coverage of the study, which is mainly focused on Ukraine and other European countries. Особистий фінансовий консалтинг: світовий досвід та перспективи розвитку в Україні 141 Findings. The results of this study indicate that Agile methodologies are becoming increasingly popular in software development teams around the world. The study also found that the use of Agile methodologies is more prevalent in smaller teams compared to larger teams. This trend may be due to the fact that smaller teams are more flexible and can adapt more easily to the iterative and collaborative nature of Agile methods. However, the data also suggests that as the complexity of a project increases, the use of Agile methods becomes less prevalent, with more traditional methods such as Waterfall being used instead. In terms of team management, the study found that the use of Agile methodologies can lead to higher levels of team collaboration and communication, which can ultimately lead to more efficient and effective project outcomes. However, it is important to note that effective team management requires more than just the use of a particular methodology, and other factors such as leadership, communication skills, and team dynamics also play a crucial role. Overall, the findings suggest that Agile methodologies can be a powerful tool for software development teams, particularly in smaller teams and less complex projects, but that effective implementation and management are key to achieving success. Originality/value. The originality and value of this study lie in the comprehensive analysis and comparison of different management methodologies in the context of team management. The study presents new insights into the advantages and disadvantages of various approaches to team management and provides practical recommendations for organizations in Ukraine and other countries. Furthermore, the study contributes to the existing body of literature on team management by providing empirical evidence on the effectiveness of different management methodologies. The study also highlights the importance of considering the size and complexity of the project when choosing a management methodology. Overall, the findings of this study can provide valuable guidance for managers and organizations in selecting the most suitable team management methodology for their specific needs and circumstances. Practical implications. The results of this study have practical implications for project managers and team leaders who are responsible for managing teams in different countries with different project sizes and complexities. Research shows that using a specific methodology does not guarantee success in team management and that an individualized approach based on the specific needs of the team and project is more effective. Overall, the practical implications of this study can help project managers improve their team management skills and increase the likelihood of project success.

This paper presents the arguments for creation and validation of a composite process framework (CASDPF) that would enable formal modeling and management of the application software development & integration. The arguments for this research are based on the practical understanding of the authors that no single 'type' of process appears to be suitable for software development projects. Increasingly, there appears to be a need to use high-ceremony 'waterfall' type approaches at the programme and project management level, whereas at individual level, 'agile' aspects of a process seem to help. A composite process framework has the potential for accepting this responsibility of balancing the modeling with software projects, as is argued in this paper. The development of software application systems, and management of the corresponding systems development life cycle is considered complex, time consuming and costly. This is so because, as argued by Unhelkar [5], the nature, type and size of software projects are different and so they result in differing requirements, development and implementation procedures.. Marks [3] indicates that the Waterfall model does not provide good project planning control and risk management. According to Marks [3], the iterative process has many strengths such as rapid feedback from users based on the actual system prototype, flexibility to address system evolving requirements, the rapid discovery of design flaws, and ease of deploying new functionality. An iterative project might run the risk of never ending process, due to its ability to react to continuous changes of business needs, and incomplete system documentation due to the fact that there is no scheduled period for documentation. The agile methods are suitable for projects with requirements that are rapidly changing and not very suitable for systems that have high criticality, reliability and safety requirements [2]. Agile methods are evaluated based on project criticality, size and requirements. Boehm [1] Spiral life-cycle model that combines features of the prototyping and Waterfall model [4] is favored for large, expensive, and complicated projects. The following model as shown in (Figure 1). Shows that the Waterfall approach is best for project management as it gives the project manager full control over the project life-cycle. The iterative approach is the best during the analysis, design and implementation phases since it gives the project team more flexibility to address evolving system requirements and to iterate within these phases to ensure a comprehensive analysis and design has been done. The Agile approach is best during the implementation and testing phases since it helps produce incremental small software releases within a short iterative development cycles. The Composite approach will split the project into a set of increments; each increment will consist of a set of the project life-cycle phases. For each increment, it will bring the best aspects of available software development processes (Waterfall, Iterative and Agile) together that can be used to develop and manage application software development.

The most critical aspect in Software Development Life Cycle (SDLC) model is of Requirement Engineering Phase various kind of complication occurred in software projects, numerous categories of requirements for software projects containing few constraints just like cost, time and a lot of more. Thus it is crucial for choosing such a lot valuable ones for implementation with intention to the delivery of a high-value system. When an instance of lack of cost and time it turns into necessary for prioritizing requirement. The proposed approach prioritize the requirement consistent with higher preference and prioritizing the Non-Functional Requirement w.r.t. Functional Requirement where cost having the principal task for prioritizing and the approach referred to as Artificial Bee Colony (ABC) algorithm based on Population meta-heuristic policy motivated by foraging behavior of bees.

The management of borrowing and returning goods in government institutions is still largely carried out manually, which often gives rise to various problems, such as difficulties in tracking borrowing histories, the high risk of recording errors, and the lack of transparency regarding the availability of goods. This condition indicates the need for support from an information system that is capable of assisting the recording process and inventory management in a more structured, systematic, and easily monitored manner. This research aims to design a prototype of a goods borrowing and returning application as an initial solution to these problems as well as a preliminary representation of a system that can be further developed by the institution. The research method used is a Research and Development (R&D) approach with a prototype Software Development Life Cycle (SDLC) model, which allows system development to be carried out gradually and flexibly in accordance with user needs. Data collection was conducted through observation and interviews to obtain an overview of the ongoing work processes and to identify the required system needs. The collected data were then analyzed as the basis for designing the system workflow, data structure, and user interface design. The results of this research are in the form of an application prototype that represents the main system features, including goods borrowing, goods returning, availability checking, goods data management, and report generation.

Patient falls and fall-related injuries are serious problems in hospitals. The Fall TIPS application aims to prevent patient falls by translating routine nursing fall risk assessment into a decision support intervention that communicates fall risk status and creates a tailored evidence-based plan of care that is accessible to the care team, patients, and family members. In our design and implementation of the Fall TIPS toolkit, we used the Spiral Software Development Life Cycle model. Three output tools available to be generated from the toolkit are bed poster, plan of care, and patient education handout. A preliminary design of the application was based on initial requirements defined by project leaders and informed by focus groups with end users. Preliminary design partially simulated the paper version of the Morse Fall Scale currently used in hospitals involved in the research study. Strengths and weaknesses of the first prototype were identified by heuristic evaluation. Usability testing was performed at sites where research study is implemented. Suggestions mentioned by end users participating in usability studies were either directly incorporated into the toolkit and output tools, were slightly modified, or will be addressed during training. The next step is implementation of the fall prevention toolkit on the pilot testing units.

The main aim of this project is to create an automated system for managing all the activities of projects. The system includes the project application and review module, project opening management module, project progress management module, project completion management module, and project research results display module, which realizes the distributed submission of project declaration, opening report, progress report, and conclusion report. Autonome integrates key quality attributes of software usability into every phase of the Software Development Life Cycle (SDLC)[10], thereby reducing latent and patent flaws and enhancing user satisfaction. By comparing various SDLC models, Autonome has been designed to fulfill diverse customer requirements, thereby addressing the industry-wide issue of underutilized software. Furthermore, Autonome facilitates effective stakeholder engagement through governance-based, value-based, and dynamism-based solutions, ensuring value delivery to all stakeholders. The system also acknowledges and addresses the inherent complexity of projects, incorporating a procedure for the quantitative assessment of structural complexity. Preliminary results indicate that Autonome significantly enhances project efficiency, stakeholder satisfaction, and team productivity. This paper delves into the design, implementation, and potential impact of Autonome, heralding a new era in project management.

Due to ever‐changing technology and business requirements, the inefficiency and ineffectiveness of traditional plan‐driven software development life cycle models are being questioned. Software engineers have to find ways of improving software development processes by applying more agile principles to the traditional plan‐driven approaches. This paper addresses this issue and suggests how project and technical management can apply principles from the agile group of life cycle models to alleviate some of the problems encountered. Project characteristics that can be used to evaluate individual projects to determine the degree to which the software life cycle can be adapted, are indicated. Practices are also proposed for adapting traditional plan‐driven life cycle processes that can benefit from more agile approaches.
