Requirement change management for global software development using ontology

Success of any software project depends on the requirements. Change in requirements at any time during the software development life cycle is considered as a healthy activity. However, managing this change in a collocated environment is relatively easier than the environment where stakeholders are scattered at more than one site. This creates ambiguity among the stakeholders, meanwhile giving rise to knowledge sharing, knowledge representation and communication challenges. Therefore, ontology can be used to minimize ambiguities among the stakeholders. We have used a case study to evaluate the developed ontology.

Effective usage of AI technique for requirement change management practices

Requirements change management is a vital activity of the software development and even after maintenance. When we change one requirement it effects the other requirements of the system. A proper impact analysis maintains a repository of changing requirement, reusing previous experiences and reduces rework effort, is also essential for better requirement change management. There is also a need of a technique which improves requirement change management in a better way. In this paper, a model has been introduced which integrates Requirement Change Management and CBR (Case Based Reasoning) technique. Expert review method is used to evaluate our research. This frame work gives a better approach which manages requirement changes to the system. Our research outcome, i.e. the CBR technique used with the RCM, can provide a better approach to solve the issues of managing changes to the system. It maintains a repository by using CBR technique which is helpful to manage changes in future and we are able to solve the new change on the basis of previous experience.

A scrum based framework for e-agriculture system

Agriculture Information systems play crucial role in the development of economy of a country. When pest and diseases affect the crops there is a significant decrease in production. Agriculture Information system has been developed by collecting information about pest, diseases, harvesting and plantation. Agile methods are best suited for the development of Information System. In the software industry, agile methods are in practice at a very large scale because of its ability of accommodating the change, quick results and high level of customers satisfaction. Scrum is an agile methodology which is used for software development. Existing Agriculture Information system is developed by applying waterfall model which has many flaws. In order to overcome those issues scrum is used for the development of agriculture system. There is no proper framework exist for the development of agriculture system using Scrum. The objective of this paper is to highlight the importance of the Scrum framework for agriculture system and suggested a framework which will support the development of agriculture system.

Knowledge management model for support of requirement engineering

Requirement engineering (RE) plays an important role in the success or failure of product and is recognized as the most critical factor in the entire software development process. Due to the fact that RE knowledge is highly dependent on human which may result in inconsistencies, terminology conflicts and lack of understanding of requirement knowledge faced in the implementation of information based applications. To address these issues we have proposed the knowledge management model for the support of RE activities. This knowledge model assists the requirement engineers and other stakeholders to share and understand the domain and instance level knowledge which results in strengthening the RE activities through continuous requirement refinement by better knowledge management model.

Knowledge modeling fore-agriculture using ontology

Agriculture is considered to be the backbone of the countrys economy. The emergence of ICT in the last couple of years has opened new challenges in the field of knowledge management concerning to distribution, sharing and integration. It is true that a lot of good practices related to agriculture are transferred without being well documented so most part of these practices remain tacit rather than explicit. Therefore, it is necessary to effectively manage knowledge for future generations before it disappears as a result of technological advancement. Knowledge management is considered as a challenge. In this paper, we have presented the knowledge management approach in the domain of agriculture, its results are presented by prototype implementation and its effectiveness has been checked by evaluation. This knowledge management approach assists the stakeholders to share and understand the domain and instance level knowledge, removes ambiguities as well as integration with other sources of knowledge compared to the traditional approaches of information management.

User-centered design practices in scrum development process: A distinctive advantage?

Agile methodology lacks in usability and most of the time issues like usability do not lead the software toward success. User-Centered Design supports usability and according to UCD, the client should be a part of the process from planning to handover phase. Integration of these two areas is a difficult and challenging task w.r.t its applicability for collocated and distributed level. This research focuses on Agile and UCD integration, providing a few practices and artifacts to guide designers and Agile teams to overcome the challenges. How UCD techniques can support Agile in order to deal with usability issues. In this paper, we have demonstrated that which are the levels and phases where stakeholders, especially the user involvement and interaction are required. Case study and observation method have been followed. The result of this research is a framework.

Role of requirement change in software architecture using Twin Peaks Model

Requirement change management is an important activity in software development. When we change our requirements it affects the other requirements of the system as well as the architecture of the system. It needs a proper approach which improves the requirement change management and its impact on architecture in a better way. In this paper a framework has been introduced which integrates the impact of requirement change in the software system by using Twin Peak Model. The expert review method is used to evaluate our research. This framework gives a better approach to measure the impact of a requirement change in the architecture of the system. Our research outcome is, to develop a framework by using Twin Peaks Model to analyze the changing requirement and gives the impact of these changes in requirements on software architecture designing. It will be helpful to manage changes in the software architecture.

A process improvement in requirement verification and validation using ontology

The success of software projects depends on fully conveyed requirements. Contribution of stakeholders contributing in software requirements have a place with distinctive domains, because of which ambiguities, inconsistencies might arise moreover giving rise to incorrectness. Many tools are available for software requirements verification and validation but the issue of stakeholders belonging to different domains is still under consideration. As these requirements are not understood properly, it causes schedule delay and greater cost in the last stages of software. Requirements verification and validation are the most vital activities in requirement engineering that guarantees software quality and has an extraordinary impact on software cost and its success. The requirements verification and validation are an affirmation that the product requirements record is free of unwanted requirements and totally reliable. Keeping in mind the end goal of removing conflict, recognizing failures and making the product requirements document completely useful is the key component. So these requirements should be appropriately confirmed and accepted by the clients before conveying to the development team. Thus, ontology might be picked as an answer for checking and approving the requirements among stakeholders of distinctive domains. In this study improving requirement verification and validation process through ontology. We have used expert reviews and case study to evaluate the developed ontology that indicates different concepts, properties and constraints in the process of requirement verification and validation. With the help of the developed ontology, it is shown that its use for requirement verification and validation shows improvement in consistency, applicability and other factors.
