Formalization of the prediction and ranking of software development life cycle models

The study of software engineering professional practices includes the use of the formal methodology in a software development. Identifying the appropriate methodology will not only reduce the failure of software but will also help to deliver the software in accordance with the predetermined budget and schedule. In literature, few works have been developed a tool for prediction of the most appropriate methodology for the specific software project. In this paper, a method for selecting an appropriate software development life cycle (SDLC) model based on a ranking manner from the highest to the lowest scoring is presented. The selection and ranking of appropriate SDLC elaborate the related SDLC’s critical factors, these factors are given different weights according to the SDLC, then these weights are used by the proposed mathematical method. The proposed approach has been extensively experimented on a dataset by software practitioners who are working in the software industry. Experimental results show that, the proposed method represents an applicable tool in predicting and ranking suitable SDLC models on various types of projects, such as: life-critical systems, commercial uses systems, and entertainment applications.

Adapting a Requirements Engineering Process by Key Factors Estimation

Literature mainly focuses the adaptation of any requirements engineering process on the possible variations of elicitation techniques, mainly due to information sources characteristics. However, these particularities, usually called situational factors, are seldom considered in other activities of the requirements process. Most situational factors, when considered in software projects, have a high influence on the requirements process. Therefore, the different situations that may attempt against or may favor a successful requirements process should be identified at the beginning of the project. Additionally, some of such factors may evolve along software development life cycle; this should motivate a reengineering of the requirements process at some strategic milestones. In this chapter, a process for constructing and dynamically adapting a requirements process is proposed, focusing on the evolving factors. The process follows rules based on different combinations of situational factors at specific control points and manages a repository of process blocks to perform the tailoring.

Routine Vaccine Simulation for Infants in a Mobile Environment

Purpose–Thisstudy aimed to develop and evaluate the Routine Vaccine Simulation for Infants. The routine vaccine simulation application was developed for the health workers and parents to provide basic information and press the importance of the vaccination to infants.Method–The researchers used the fourth-generation technique (4GT) for the software development life cycle of the application. The technique adapted contains four major parts namely, requirements gathering, design strategy, implementation, and testing.Results–The application was tested and evaluated by health workers, parents, and IT practitioners from the academe and the industry. The evaluation was based on criteria for core app quality. Descriptive and inferential statistics were employed for data presentation and interpretation. As a whole, the evaluation of the android-based routine vaccine simulation application was found excellent in most of its features. The finding asserts the adherence to the standards of android developmentapplicationsand conforms to the expectations of the app’s potentialusers. Conclusion–The development of a routine vaccine app for infants serves as a new platform for immunization awareness and education. Once information given in the app is taken earnestly, infants will be protected against diseases. Thus, controversies surrounding vaccination hesitancies can be decreased.Recommendations–A thorough information dissemination and education campaign regarding vaccine safety can be initiated in the local communities to address the issues on vaccine safety and hesitancy.Research Implications–The healthcare system in the communities through the local government unit (LGU) willbe able to benchmark and implement the information dissemination and education to mothers and health workers using the app.

Application of Design Thinking Methodology to the Various Phases of the Software Development Life Cycle

Design thinking is often thought of as a creative way of problem solving. People are told to believe what they are told and what they read, and with that is the downfall of creativity. Designers need to see the world through the eyes of a 5-year-old. People needs to give themselves permission to be creative. It takes intelligence to answer a question, but it also takes creativity to answer the question. People have to imagine the world as it never existed before. Design thinking can be termed as “consumer-centric”, “end-user centric” or simply “human-centric” thinking. It works from the perspective of the user in general with user satisfaction being the primary goal. The methodology that I adopted is thinking from the user's perspective and working towards user's satisfaction as the goal. Design thinking is a problem-solving technique evolved in different fields like architecture, engineering, and business. The key element to the success of designing a software system lies in user participation. Therefore, it was basically developed to derive a solution by understanding the user's need.

An Early Multi-Criteria Risk Assessment Model

Accurate time and budget is an essential estimate for planning software projects correctly. Quite often, the software projects fall into unrealistic estimates and the core reason generally owes to problems with the requirement analysis. For investigating such problems, risk has to identified and assessed at the requirement engineering phase only so that defects do not seep down to other software development phases. This article proposes a multi-criteria risk assessment model to compute risk at a requirement level by computing cumulative risk score based on a weighted score assigned to each criterion. The result of comparison with other approaches and experimentation shows that using this model it is possible to predict the risk at the early phase of software development life cycle with high accuracy.

A Software Development Life Cycle Case Study Of Lean IT With Value Stream Mapping Analysis

Value Stream Mapping (VSM) is a useful tool for depicting the flow of materials and information in manufacturing and service processes. It is known as one of the most popular lean methods to identify bottlenecks, reduce cycle time, and improve current processes. Although VSM has been extensively used in manufacturing, there are limited studies that applied VSM in non-manufacturing environments. In this study, we present an application of VSM to improve Software Development Life Cycle (SDLC) process in an IT firm. The current process flows (as-is) are mapped to identify non-value-added activities as well as areas for improvement. Based on the analysis of the current state map, we propose recommendations, action plans, and a future state map (to-be-process). We estimate that, with the new process changes, IT project delivery time can be reduced from 210.5 days to 137.5 days – a 34.7% reduction in the software development life cycle process. This provides a powerful base for IT project management and enables the IT department to meet its expected project turnaround time.

Analysis of Low Code-No Code Development Platforms in comparison with Traditional Development Methodologies

This paper examines the overview of low-code/no-code development platforms in comparison with traditional development methodologies and examines the benefits and limitations of the same. For several decades, businesses have had multiple options when they demanded new information systems. They could develop a new system using in-house developers, or they could order a system from an external merchant. This offers a close fit to business obligations. However, nowadays, there is a new alternative that is becoming increasingly prevalent. Low code/no code (LC/NC) applications can cater to business requirements efficiently, can be implemented instantly, and the cost is much less than systems developed in-house. Few, if any, programming skills are required. Keywords: Traditional development, No code development, low code development, Low code No code development, Software development life cycle (SDLC)
