Migration of legacy systems to more advanced technologies and platforms is a current issue for many software organizations. Model-Driven Modernization combined with Software as a Service delivery model is a very promising approach, which possesses a lot of advantages, including reduced costs, automation of migration activities and reuse of system functionality. However, a drawback of such an in...

We present a software process model that can be effectively applied to the agile software development context. Our approach builds an ideal agile software process model starting from the principles established by the agile community in what is known as the Agile Manifesto. The practices defined by the ideal model can be used to assess the various agile methods to determine any missing or under-...

A highly productive team throughout an agile software development process is very instrumental in achieving project success. This research presents a system dynamics (SD) based approach to model agile software development teamwork productivity by analyzing productivity influence factors. Identification of main factors influencing productivity and how they impact agile teamwork are carried out t...

There appears to be a lack of knowledge on the phases South African (SA) organisations go through while adopting agile methods. As a means to address this gap, this study uncovered empirical evidence on the phases SA organisations go through whilst adopting agile methods as well as the disparities between agile prescriptions and the way SA organisations actually implement agile methods. The dat...

Our research aims at finding key concepts to link agile enterprises with agile automated information systems. To effectively respond to environmental changes, such as in market needs, technology, regulations or law, enterprises need to be able to change their supporting information system(s) accordingly. The Design and Engineering Methodology for Organizations (DEMO) has already proven to be an...

This paper presents a case study on the procedures and practices of the new approach to agile programming which is named as scrum XL, Need for a new approach was identified in my earlier paper called “Agile Programming-A New Approach”[1] . The approaches mentioned in this paper were implemented in a real working environment. It explains the features that have been successfully put into practice...

I n recent years, the use of, interest in, and controversies surrounding agile methods have all increased dramatically—as has anecdotal evidence for agile methods’ effectiveness in certain environments and for specific project types. Exactly in which environments and under what conditions agile methods work remains unclear, however. A development team at Motorola, for example, noted that, “a pl...

Requirements are critical for the success of software projects. Requirements are practically difficult to produce, as the hardest stage of building a software system is to decide what the system should do. Moreover, requirements errors are expensive to fix in the later phases of the software development life cycle. The rapidly changing business environment is highly challenging traditional Requ...

Innovative companies need an agile approach for the engineering of their product requirements, to rapidly respond to and exploit changing conditions. The agile approach to requirements must nonetheless be systematic, especially with respect to accommodating legal and nonfunctional requirements. This paper examines how to support a combination of lightweight, agile requirements which can still b...
