From the literature, it is evident that there are various kinds of process models that are used by the software industries for the development of small, medium and long-term software projects, but many of them do not cover risk management. It is quite obvious that the improper selection of the software development process model leads to failure of the software products as it is time bound activity. In the present work, a new software development process model is proposed which covers the risks at any stage of the development of the software product. The model is named a Hemant-Vipin (HV) process model and may be helpful for the software industries for development of the efficient software products and timely delivery at the end of the client. The efficiency of the HV process model is observed by considering various kinds of factors like requirement clarity, user feedback, change agility, predictability, risk identification, practical implementation, customer satisfaction, incremental development, use of ready-made components, quick design, resource organization and many more and found through a case study that the presented approach covers many of parameters in comparison of the existing process models. .展开更多

To perform this analysis, it was adopted a standard structure to define a software process based upon a process ontology. Then, the SPEM and BPMN standards notations and their semantically corresponding elements in the default process were identified. This mapping also includes components of the CMMI-DEV (Capability Maturity Model Integration for Development) and MR-MPS (Reference Model for Software Process Improvement) quality models. This was necessary to assist in the mapping evaluation through a case study which models the best practices of these quality models. Finally, we carried out an analysis of these standards through specific characteristics considered necessary to model and to represent software processes.展开更多

Although a number of empirical studies have established the reality of these gains, there are still lots of reluctances toward the adoption of MDE in practice. This resistance can be explained by several technological and social factors among which a natural scepticism toward novel approaches. In this paper we attempt to provide arguments to help alleviate this scepticism by conducting an assessment of a MDE approach. Our goal is to show that although this MDE is novel, it retains similarities with the conventional Software Engineering approach while automating aspects of it.展开更多

On the other hand, the emergence of model engineering aims to raise the level of abstraction to allow developers to reason on models, and less in code. The research question is to combine the two approaches to facilitate the work of developers. The proposal resulting from this study is based on a set of concepts defined using the UML profiles. These concepts include services, business components, and data persistence. Then the Kruchten model is adopted to represent the development cycle according to several views, each view being represented by UML diagrams derived from the previously defined profiles. Finally, rules are available for checking inter-view consistency, from refinement to code generation. The result is a step towards the definition of a domain specific ADL and a development process as much as it includes the expected characteristics of such a language, namely: the fundamental concepts, the support tools and the multiview development.展开更多

The presented approach enables modelling of control software in a straightforward manner and, at the same time, on a high level of abstraction. The essence of the presented approach is a high-level, domain-specific modelling language ProcGraph, which is based on three types of diagrams that describe the modelled system using a domain-oriented hierarchical structure of interdependent procedural control entities and state-transition diagrams describing the behaviour of the procedural control entities. The presented concept is demonstrated by means of higher-level model segments of a real process-control application that deals with the micronisation process in the production of titanium dioxide. The presented industrial case shows that the application of ProcGraph provides adequate expressive power for an elegant preparation of graphic specifications in a transparent and easy way.展开更多
