Conceptual Mappings of Conventional Software and Machine Learning-based Applications Development

The software development process model or what is commonly called SDLC (Software Development Life Cycle) is one of the Software Engineering (RPL) course materials in the Information Engineering Education (PTI) undergraduate study program where one of the competencies is understanding and knowing the concepts of device engineering software that can be applied in the software development life cycle which is summarized in the material for the SDLC software development process model. This material is the initial material that must be mastered by students to develop quality software. The use of interactive and interesting computer assisted learning media is expected to help the stages of the student learning process properly. This requires an interactive learning multimedia application. The purpose of this research is to develop interactive learning media as an alternative to independent learning tools to assist students in mastering the Software Development Process Model (SDLC) material for students and to find out the feasibility of multimedia application products for learning the Software Development Process Model (SDLC). The research and development methodology used in this research is Research and Development (R&D) with Borg and Gall's development steps which include: (1) Research and data collection; (2) Planning; (3) Development of product drafts; (4) Initial field trials; (5) Revision of trial results (6) Field trials; (7) Product improvement; (8) Field implementation test; (9) Completion of the final product; and (10) Dissemination of implementation. This methodology covers all matters relating to development to produce quality interactive learning media software. Based on the trials, the results obtained were 90.63 percent from media experts, 98.08 percent from material experts, 85.46 percent from initial field trials, 84.56 percent from field trials, and 86.27 percent from field implementation trials. The average value obtained is 89 percent based on the results of the overall data analysis. The conclusion of this research is that the development of multimedia applications for learning the Software Development Process Model (SDLC) is feasible as an independent learning medium. The product produced in this development research is a multimedia application for learning flash-based software development process (SDLC) models.

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.

Cybersecurity risks are increasing in frequency and complexity, but many organizations struggle to plan and implement adequate protections at all stages of the software development life cycle (SDLC). Security is frequently added at the end of development (afterthought), and making effective use of safeguard space is difficult for IT leaders. The purpose of this study is to produce an all‐encompassing framework to adopt and ensure security throughout each phase of the SDLC, from planning through maintenance. The aim is to minimize vulnerabilities and improve the resilience of software by making “security by design” a structure that not only adopts security elegantly as a living document but also is built to be part of the development process. This study adopted a mixed‐methods approach. The initial stage of inquiry involved a systematic literature review (SLR) to identify common cybersecurity issues associated with each SDLC phase. The SLR was followed by an empirical survey of 71 software professionals from a variety of organizations. The survey was designed to gather perceived threats, current practices, and challenges associated with software development for survey participants' organizations. The data collected were analyzed and reviewed statistically, through chi‐square tests and ANOVA, to profile the variance relative to the size of the organization, geographic region, and experience level of the practitioner. The results noted several high‐risk challenges across the SDLC: underfunded security controls, imprecise requirements, insecure architecture, software bugs (i.e., injection vulnerabilities), inadequate testing, misconfigured production environments, and unreliable maintenance. The proposed framework provides cybersecurity mitigation techniques for each stage of the SDLC, such as leveraging security‐oriented design patterns, secure coding policies (i.e., input validation and authentication protocols), robust testing (i.e., penetration testing and code review), and continuous monitoring after deployment. The implementation of these measures leads to a significant risk reduction in the overall organizational security posture. The framework is a formalized end‐to‐end approach to secure software development by embedding security throughout the cycle. Embedding security as a part of the process versus an afterthought at every stage of the cycle creates a risk reduction impact. This integrated approach also provides organizations with the opportunity to foresee and mitigate events earlier in the cycle, along with general compliance mandates (i.e., GDPR, HIPAA, and PCI‐DSS), to provide more resilient, trustworthy software systems.

The purpose of this chapter is to introduce scientific software developers to software engineering tools and techniques that will save them much blood, sweat, and tears and allow them to demonstrate the quality of their software. By introducing ideas around the software development life cycle, source code analysis, documentation, and testing, and touching on best practices, this chapter demonstrates ways in which scientific software can be improved and future developments made easier. This is not a research article on current software engineering methods, nor does it attempt to specify best practices. Its aim is to introduce components that can be built into a tailored process. The chapter draws upon ideas of best practice current in software engineering, but recommends using these only selectively. This is done by presenting details of tools that can be used to implement these ideas and a set of case studies to demonstrate their use.

The avionics display is the most critical part of an aircraft. The display provides the Human–Machine Interface (HMI) or Human–Computer Interface (HCI) for the pilot. The display, a safety–critical system in aircraft which gives essential information about the aircraft. The hardware and software of the safety–critical avionics system are established depending on RTCA guidelines such as DO 178B. In this paper, we propose a method to create an HMI for a safety–critical system using graphical libraries. The aim is to develop a display for the two-seater aircraft. The avionics display comes under criticality level A which requires perfect software development following the standards for safety criticality. The application software development is based on Software Development Life Cycle (SDLC). The GUIs are created using the OpenGL library available. The software developed was tested in real-time using a 7-inch Thin Film Transistor (TFT) display using BCM2837 microprocessor.

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.

The software development life cycle (SDLC) is a structured process for delivering a high-quality product within a specified timeframe. Developing a cost-effective and efficient software product life cycle has always been a priority in software engineering, which can impact product quality. This study aims to provide an overview of the recent articles that focus on applying optimization techniques, mathematical models, and software cost estimation in the software development process and propose possible future directions. For the selected 29 studies, the development phase of the SDLC is most commonly focused on in studies. This emphasis highlights the pivotal role of optimization and mathematical modeling in enhancing software development efficiency.

Accessibility modifications are required for individuals with situational, temporary, or permanent impairments to properly interact with web applications. Incorporating accessibility guidelines, such as the Web Content Accessibility Guidelines (WCAG), into software development, along with the software development life cycle and other paradigms, poses challenges. The linear progression of steps in a conventional software development process leads to the identification of problems at a later stage because testing is typically conducted toward the end. Limited attention to accessibility until the final development phase results in prolonged efforts, increased resource allocation, and higher expenses to address accessibility issues. Consequently, numerous software applications remain inaccessible to users with impairments. This study focuses on a Shift Left-based model to improve accessibility in the software development process. Employing the Shift Left a11y Model that emphasizes early integration for accessibility and coupling it with the Extreme Programming Development Life Cycle would enhance the integration of various testing practices and facilitate the development of software that is accessible to all users, including those with impairments. Keywords: Accessibility, accessible software, shift-left, model, methodology for accessible software

The rise in software development has intensified reliance on complex applications across sectors. However, this growth is paralleled by increased cybersecurity threats, revealing critical vulnerabilities within the Software Development Life Cycle (SDLC). Agile and DevOps methodologies, while offering speed and adaptability, often overlook vital security concerns, thus heightening exposure to cyber risks. This study addresses a novel research gap by examining how discrepancies in security integration across SDLC methodologies can lead to significant gaps in cybersecurity posture. Using a combination of case study scenarios, literature-informed analysis, and focus groups with subject matter experts, this research presents a comprehensive applied approach to cybersecurity in software development. Notably, the study engages participants with advanced expertise and real-world experience, whose insights enhance understanding of secure SDLC integration’s theoretical and practical aspects. This multi-method approach provides emerging cybersecurity professionals with actionable hands-on strategies to identify and mitigate vulnerabilities, aligning with current industry standards. The study’s findings underscore the urgency of standardized security practices within the SDLC, contributing to developing industry-wide best practices prioritizing security alongside speed and flexibility. By bridging theoretical frameworks with applied research, this study offers significant advancements for cybersecurity education and industry practice, preparing future professionals to address evolving cybersecurity challenges effectively.

Crowd sourcing, citizen journalism and social networks are Information and Communications Technologies (ICT) that have ushered in civil society's participation in the ICT equation. However, the participation of civil society has been limited to creating content and, to some extent, capturing data about events around the community. An area that has been neglected is the inclusion of these new players in the software development life cycle. Democratizing software development by including civil society in the software development life cycle will increase the variety of software applications and generate more buy-in of applications that improve livelihoods. Such an approach will lead to the emergence of Inclusive Information and Communication Technologies (IICT). The challenges that arise when developing IICTs include, inter alia, ownership of IICT, computer illiteracy of beneficiary communities, balkanized nature of communities in place and the well-known challenge of the communication gap between software developers and user communities. My approach to addressing these challenges was to develop the Integrated Development Spatial Planning Framework (IDSPF), a systems development methodology that seeks to demystify software development for grassroots communities by using participatory techniques that are familiar to stakeholders who implement socio economic development projects.

Application development has progressed along with the rapid digital transformation. The stakeholders will focus more on cutting operational costs with optimal application quality and security. The DevSecOps approach provides solutions for reducing costs in the software life cycle, increasing software product quality and security. Public Company Logistic Agency (PCLA) is like other companies that must be adaptive to new technology. PCLA has an IT Division in charge of providing technology to support business. Application development by the IT Division has several problems, including application projects that mostly exceed the time, significant changes and additions during UAT, and applications that have much vulnerability. A transformation to the DevSecOps approach is needed to address these problems. In this paper, a Systematic Literature Review (SLR) was used to select journals that matched the study topic to obtain the character and transformation phases of DevSecOps in various case studies. A mixed-method approach aims to collect and analyze data companies in the software development lifecycle. For academicians, this study provides a new understanding of application development in a state-owned enterprise based on a sequential approach and their suitable solutions from the DevSecOps approach. For practitioners, the findings provide potential lessons learned and guide a state-owned enterprise to transform to the DevSecOps approach.

Contemporary software is increasingly developed using an agile development approach, yet the supplier is generally selected as a result of a waterfall-style competitive tendering and contracting process. The procurement activity may be incompatible with an agile elaboration of requirements and development of functionality, and lead to sub-optimal outcomes. This paper examines the interaction of the procurement and software development lifecycles, explores potential causes of project or system failures and suggests some improvements based on a successful 10 year project between ADI Limited and the Australian Department of Defence.

Patterns are a means for capturing experience in solving general problems. They give general solutions to common and recurring problems. They exist at various phases of the software development life-cycle (SDLC), namely the analysis phase, the design phase, the coding phase and the testing phase. Patterns in each phase are identified independently. It is possible for the patterns of one phase to be related to patterns in other phases. This paper proposes pattern mapping to inter-relate the patterns of various phases in SDLC to address this issue. It is advantageous to capture the related patterns of different phases as a single unit for software development. Reusable integrated components (ICs) of patterns are proposed to capture the related patterns. A software IC is a group of inter-related patterns, that gives solutions for a recurring problem at various phases of SDLC. A representation mechanism for ICs is presented using the URA (Unified Representation of an Artifact) model, which captures the software development process. Also, this paper proposes a software development process that is based on reusable ICs of patterns. The representation of a software project developed using ICs is also discussed.

Uptake of HCI and usability engineering by software development organisations can be terminally impeded by lack of appreciation of the benefits of HCI activities. However, descriptions of HCI offerings in terms of activities (e.g. task analysis, user mapping, allocation of function, interaction design) and methods (e.g. user profiling, prototyping, GOMS modelling) do not convey to product managers a readily comprehensible conception of the value of such offerings. Similarly, descriptions of HCI activities and methods give little indication of how these are to be associated and managed with reference to stages and deliverables in a software development life cycle. This lack of clear association between usability engineering and software engineering contributes to the marginalisation of usability related activities. Even when investment is made in usability resources its eventual pay off can be minimal, with resulting disillusionment on both sides. Specification of usability deliverables can provide a solid basis for a manageable usability perspective on the development of software products. The article identifies usability deliverables and describes their content and relation to deliverables in a software design and development process. More general implications for an approach to the specification of quality processes for the creation of interactive software products are discussed.
