A Comparative Study of Agile and Waterfall Software Development Methodologies

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

Dual-Activation Emergency Situation Notification System: A Feature Driven Development Approach

Emergencies can unpredictably arise, posing severe threats to individuals' lives. Swift and effective communication plays a crucial role in promptly relaying vital information to relevant response agencies and loved ones, aiming to minimize or eliminate the impact of such disasters. Existing systems often require manual triggering of distress signals through button presses or image captures. However, these methods can be ineffective, particularly when victims are under the surveillance of wrongdoers, rendering them unable to discreetly use their devices. To address this issue, this study introduces the Dual-Activation Emergency Situation Notification System (DA-ESNS) model, which ensures that potential wrongdoers remain unaware of the user's attempt to seek help by employing an efficient communication and alerting system during emergencies. Through a review of previous models, the DA-ESNS model was developed to address identified gaps. The Feature Driven Development software development process model was selected due to its agile and incremental nature, enabling focused development and integration of the notification feature. ReactJS and NodeJS were utilized for frontend and backend development, respectively. The integration of Twilio API and Geolocation API facilitated SMS notifications and precise location sharing with emergency response teams and predefined contacts. The DA-ESNS model automatically relays distress signals by persistently listening for predefined keywords or manually triggered by clicking on corresponding emergency cards, notifying both the emergency response team and the victim's family members. The model was implemented across various mobile platforms, providing a centralized and interactive interface. By offering quick notifications and offline accessibility, the DA-ESNS model streamlines the emergency alert process, significantly improving the effectiveness of emergency response teams in reducing the impact of crises through rapid reaction times. As a result, the DA-ESNS model emerges as a valuable and effective tool in emergency management.

Activities and Practices of Requirements Engineering in Agile Software Environments

Requirements are one of the important factors for software success. However, Requirements Engineering (RE) activities, in the Waterfall process model, are done sequentially in the analysis phase, which makes it difficult when RE practitioners think and reason about them in Agile Software Development (ASD) process model. RE practitioners need to find the established RE activities conventions in the ASD process model, especially with an increase of software companies, which transform to the ASD process model, in order to foster their transition to the new model. The objective of this study is to provide RE activities in ASD to allow RE practitioners to utilize the appropriate activity for specific ASD methodology. RE activities in ASD are handled repetitively and on a small scale, which makes them embedded in the development life cycle. This paper focuses on highlighting them in different ASD methodologies and discusses the practices that resolve the traditional Waterfall model issues. Although the ASD model has resolved some traditional RE issues, it introduced other issues, such as a consequence of trying to achieve an adequate balance between agility and stability. In addition, there is a lack of practices that target non-functional requirements.

An Exploratory Study Gathering Security Requirements for the Software Development Process

Software development stands out as one of the most rapidly expanding markets due to its pivotal role in crafting applications across diverse sectors like healthcare, transportation, and finance. Nevertheless, the sphere of cybersecurity has also undergone substantial growth, underscoring the escalating significance of software security. Despite the existence of different secure development frameworks, the persistence of vulnerabilities or software errors remains, providing potential exploitation opportunities for malicious actors. One pivotal contributor to subpar security quality within software lies in the neglect of cybersecurity requirements during the initial phases of software development. In this context, the focal aim of this study is to analyze the importance of integrating security modeling by software developers into the elicitation processes facilitated through the utilization of abuse stories. To this end, the study endeavors to introduce a comprehensive and generic model for a secure software development process. This model inherently encompasses critical elements such as new technologies, human factors, and the management of security for the formulation of abuse stories and their integration within Agile methodological processes.

ACCELERATION OF LEARNING MANAGEMENT SYSTEM APPLICATION DEVELOPMENT IN THE EDUCATION SECTOR USING THE LOW CODE CONCEPT ON MICROGEN

The background of this research is to speed up application development which tends to take a long time. To respond this, researchers apply the concept of "Low-Code" referring to a software development approach by speeding up the manufacturing process by reducing the amount of code that needs to be written manually to be automated using the microgen platform. This research was tested on a case study of the development of a Learning Management System, making it faster and more efficient.

On Fuzzy and Case-Based Dynamic Software Development Process Modeling and Simulation Approach

The software development process (SDP) is complex because it uses specific knowledge, skills, tools, and techniques to deliver value to people, and the user’s needs are always growing and becoming more complex. Practitioners and academics have proposed different approaches for improving the successful implementation of the SDP. This remains a non-trivial task, and the number of successful software development projects increases only slightly each year. This paper proposes a new approach for adapting the classical SDP to a dynamic, knowledge-intensive, and context-dependent model by applying the case-handling and fuzzy inference approaches for SDP modeling and simulation. The advantages and novelties of this approach consist in: SDP dynamicity modeling using the case-handling approach; the inclusion of human factor uncertainty into the execution of SDP activities through fuzzification; and agent-based simulation, which allows for the inclusion of human actors in SDP simulations. Modeling and simulation of Agile SDPs were carried out using this prototype. Experiments show the correspondence of the proposed approach to the needs of dynamically changing and human-factor-dependent SDPs, as well as the possibilities for modeling and simulating the SDP, predicting SDP execution, and observing possible risks.

Macrosimulation Model of Software Development Process

Managing software development processes remains a severe challenge despite the support of tools. To remedy this situation, we propose better use of data collected in management support systems, a light approach to planning inspired by agile approaches, and the premise that continuous changes are inevitable. This approach lies at the heart of the described solution.The article presents a simplified software development process model that classifies project work in task types and roles of project team members, uses statistics to generate tasks, and then aggregates the results in iterative (month or sprint) and incremental approaches. The simplicity of macrosimulation allows for implementation in a spreadsheet. Despite its simplicity, the model allows for analysis of the completed project work, planning further courses, selecting employees for the project team, identifying bottlenecks, and performing quick what-if simulations. The macro model concept explains its structure, operation, and components details. Three experiments demonstrate its replicative and predictive capability, using data from real-world IT industry software projects.

Statistical analysis of software development models by six-pointed star framework.

Software Development Process Model (SDPM) develops software according to the needs of the client within the defined budget and time. There are many software development models such as waterfall, Iterative, Rapid Application Development (RAD), Spiral, Agile, Z, and AZ model. Each development model follows a series of steps to develop a product. Each model has its strengths and weaknesses. In this study, we have investigated different software development process models using the six-pointed star framework. Six-point star is a framework of project management industry standards maintained by Project Management Body of Knowledge (PMBOK). A survey is designed to evaluate the performance of well-known software process models in the context of factors defined by the six-point star framework. The survey is conducted with experienced users of the software industry. The statistical analysis and comparison of results obtained by the survey are further used to examine the effectiveness of each model for the development of high-quality software concerning lightweight and heavyweight methodologies for small, medium and large scale projects. After exploring the results of all factors of the six-pointed star model, we conclude that lightweight methodology easily handles small-scale projects. The heavyweight methodology is suitable for medium and large-scale projects, whereas the AZ model, which is one of the latest models, works efficiently with both small-scale and large-scale categories of projects.

Strengthening Software Make vs. Buy Decision: A Mixed-Method Approach

Over the past few decades, multiple software development process models, tools, and techniques have been used by practitioners. Despite using these techniques, most software development organizations still fail to meet customer’s needs within time and budget. Time overrun is one of the major reasons for project failure. There is a need to come up with a comprehensive solution that would increase the chances of project success. However, the “make vs. buy” decision can be helpful for “in time” software development. Social media have become a popular platform for discussion of all sorts of topics, so software development is no exception. Software developers discuss all the pros and cons of making vs. buy decisions on Twitter and other social media platforms. Twitter trending is a typical feature that evaluates the level of popularity of a specific event on online networking. A mixed-method approach comprising of interviews of software industry experts and Twitter data extraction is applied to scrutinize the effective decision of software build vs. buy decision. The findings of the analysis show that software makes vs. buy decisions depend on several factors including cost, development technology, software development team skills, and time. Based on the finding of the study a framework is proposed for the decision to build versus buy in Small and medium-sized enterprises (SMEs). Furthermore, the framework has been designed to statistically indicate make versus buy decisions of the organization and to suggest appropriate choices based on different parameters.

BENCHMARKING METODE RANCANG BANGUN WATERFALL DAN PEMODELAN BERBASIS OBJEK

This research is a research Benchmarking Waterfall Design Method and Object-Based Modeling. Software development has many models, software methodologies have evolved from time to time, including the Waterfall approach and the UML (Unified Modeling Language) approach. Waterfall is a software development model that is carried out sequentially and very systematically. Meanwhile, UML is a visual modeling method that serves as a means of designing object-oriented systems. The difference between the two models is that Waterfall is a structured method, while UML is a system analysis method, a representation of the programming method. This study aims to perform a comparison or benchmarking of each of these software models, which can assist in determining the most suitable model for the current software development process. The method used in this research is descriptive quantitative method, which analyzes data by describing or describing the data that has been collected as it is. From the results of this study, it can be concluded that the UML method is most suitable for software development, because UML in terms of development, is a method that has undergone evolution from previous methods, so this method can follow the use of users in designing projects on a medium to large scale. That are relevant to the current developments

Analytical study of software development process model variants

Software Engineering is a branch of Computer Science that evolved as a result of urgent need to deal with decades of software crisis, characterized by low theoretical knowledge and practice of the construction of error-free and efficient software. The introduction of well-organized scientific, engineering and management strategies in the process of software development no doubt led to major breakthroughs, and solutions to software failures. One of the obvious game-changer in this regard is the evolution of Software Development Life Cycle, also known as Software Process Model for driving the different phases of software construction. A sound understanding of the process model is therefore inevitable, not just for software developers, but also to users and researchers. Such a theoretical cum practical understanding will enhance decisions on which process model is best for a particular job or perspective. This invariably, contributes immensely to the probability of success or failure of the project in question. Thus, the necessity for this research.
