In modern times, competitiveness in the market depends on having a good information system. The companies developing and supplying information systems are in competition too, and having an effective system of delivery is critical for obtaining lucrative offers. Therefore, the software development companies continuously try to improve their development process to supply the product in a short time and with high quality. The agile approach potentially shortens this time and is very often used. This approach has almost replaced the traditional process. More and more companies implement agile approach in these times to be competitive in the software development market and hasten product delivering.The traditional and agile approaches differ in certain perspectives. Hence, the question arises as to whether the agile approach is the best for the software development company in every case. This article contains a comparison of these two approaches, as well as a case study relating to the agile approach in a real software development company, which had previously used the traditional approach. The article also describes situation where replacing the traditional approach with agile would improve results.

The Model-Driven Development (MDD) approach shifts the focus on code to models in the software development process. In MDD, model transformations are elements that play an important role. MDD-based projects evolve along their lifecycle in a way that changes in their transformations are frequent. Before applying changes it is important to measure their impacts within the transformation. However, currently no technique helps practitioners in this direction. We propose an approach to measure the change impact in ATL model transformations. Based on static analysis, it detects the elements impacted by a change and calculates the change impact value through three metrics we defined. By using our approach, practitioners can (i) save effort and development time since the elements impacted with the change are automatically detected and (ii) better schedule and prioritize changes according to the impact value. To empirically evaluate our approach we conducted a case study.

BACKGROUND Individuals with disability and their partners, who often provide care, are both at risk for depression and lower quality of life. Mobile health (mHealth) interventions are promising to address barriers for mental health care. Rehabilitation researchers and software development researchers must collaborate effectively with each other, and with clinical and patient stakeholders to ensure successful mHealth development. OBJECTIVE To aid researchers interested in mHealth software development by describing the collaborative process between a team of rehabilitation researchers, software development researchers, and stakeholders. Thus, we provide a framework (conceptual model) for other teams to replicate in order to build a web-based mHealth app for individuals with physical disability. METHODS Rehabilitation researchers, software development researchers, and stakeholders (people with physical disabilities and clinicians) are involved in an iterative software development process. The overall process to develop an mHealth intervention includes initial development meetings and a co-design method called “designbox”, in which the needs and key elements of the app are discussed. Based on the objectives outlined, a prototype is developed and goes through scoping iterations with feedback from stakeholders and end-users. The prototype is then tested by users to identify technical errors and gather feedback on usability and accessibility. RESULTS Illustrating the overall development process, we present a case study based on our experience developing an app (SupportGroove) for couples coping with spinal cord injury. Examples of how we addressed specific challenges are also included. For example, feedback from stakeholders resulted in development of app features for individuals with limited functional ability. Initial designs lacked accessibility design principles made visible by end-users. Solutions included large text, single-click, and minimal scrolling to facilitate menu navigation for individuals using eye-gaze technology. Prototype testing allowed further refinement and demonstrated high usability and engagement with activities in the app. Qualitative feedback indicated high levels of satisfaction, accessibility, and confidence in potential utility. We also present key lessons learned about working in a collaborative interdisciplinary team. CONCLUSIONS mHealth promises to help overcome barriers to mental health intervention access. However, the development of these interventions can be challenging because of the disparate and often siloed expertise required. By describing the mHealth software development process and illustrating it with a successful case study of rehabilitation researchers, software development researchers, and stakeholders collaborating effectively, our goal is to help other teams avoid challenges we faced and benefit from our lessons learned. Ultimately, good interdisciplinary collaboration will benefit individuals with disabilities and their families. CLINICALTRIAL n/a

Model-driven software development is surrounded by numerous myths and misunderstandings that hamper its adoption. For long, our students were victims of these myths and considered MDSD impractical and only applied in academy. In this paper we discuss these myths and present our experience with devising an MDSD course that challenges them and motivates students to understand MDSD principles. The main contribution of this work is a set of MDSD teaching guidelines that can make the course pragmatic in the eyes of students - programmers. These guidelines introduce MDSD from the viewpoint of a programmer as a pragmatic tool for solving concrete problems in the development process. In our MDSD course we implemented the presented guidelines. The course shows several techniques and principles of model-driven development in multiple incremental iterations instead of concentrating on a single tool. At the same time we unite these techniques by using a dynamic visualisation tool that shows to the students the whole infrastructure in the big picture. The course is implemented as an iterative incremental MDSD case study. The paper concludes with a survey performed with our students that indicates positive results of the approach.

Reusability is a clear principle in software development. However, systematic reuse of software elements is not common in most organizations. Application programmers rarely design and create software elements for possible future reuse. In many agile software development processes, the project teams believe that the development of reusable software elements can slow down the project. This can be a misconception. This chapter examines various ways to reuse software. Three approaches to developing reusable software artifacts from 15 years of experience in the agile development process are presented. The first approach is to create generic programs or configurable frameworks that support similar solutions for a variety of use cases and environments. The reuse of patterns is the second approach presented. Another effective way is to use a model-driven approach with model patterns. These approaches help to speed deployment software. The final product is flexible and can easily be adapted to changes. This is one of the main goals of an agile approach.

During the past years, new software development approaches were introduced to suit within the new trend of the software development corporations. Most Software Corporation’s today aim to provide valuable software in short period of time with marginal prices and among unstable, ever-changing environments. Agile methodology focuses on the challenges of unpredictability of the real world by relying on individuals and their creative thinking instead of method. In this paper we tend to explore about the current agile methods, strengths and weaknesses of agile strategies and numerous problems with their relevancy. We have conjointly enclosed comparison between traditional software development process and agile software development process. This paper also includes brief discussion about the benefits and problems associated with these methodologies by performing case study of two corporations.

Purpose – Explains how companies that are seeking to implement rapid innovation can adopt the Agile software development approach. In Agile, self-organizing teams work in short cycles called “sprints” and develop the features to enable the product to continuously evolve in the light of the experience they gain and through customer feedback. Design/methodology/approach – For insight into how Agile is being implemented at a leading software services firm with clients in hundreds of industries, Strategy & Leadership asked Rob Purdie, Agile Practice Lead for the IBM Design Lab, how Agile software development methods were contributing to the success of IBM's key digital marketing initiatives. Findings – The traditional approach to software development is to define, design, develop and test everything – before delivering anything. With Agile, managers can reduce waste by prioritizing features based on relative business value, evaluating and re-designing as the project proceeds. Practical implications – Agile requires leaders and teams to work and learn through problems, designs and options in an open and transparent environment. It places new demands on technical leaders in terms of negotiation and planning skills. Originality/value – Managers outside the software industry should note that Agile/Scrum is likely to be increasingly essential to the future of product development and manufacturing. Nowadays many products for consumers and businesses include embedded software systems, so developing products in the future will require deeper collaboration across multiple engineering disciplines and marketing teams and familiarity with the Agile approach.
