Abstract

The paper aimed to address the problem of incompleteness and inconsistency between requirements and design stages, and how to make efficient linking between these stages. Software requirements written in natural languages (NL), Natural Language Processing (NLP) can be used to process requirements. In our research we built a framework that can be used to generate design diagrams from requirements in semi-automatic way, and make traceability between requirements and design phases, and in contrast. Also framework shows how to manage traceability in different levels, and how to apply changes to different artifacts. Many traceability reports can be generated based on developed framework. After Appling this model we obtained good results. Based on our case study the model generate a class diagram depends on central rule engine, and traceability was built and can be managed in visualize manner. We proposed to continue this research as its very critical area by adding more Unified Modeling Language(UML) diagrams, and apply changes directly inside software requirement document.

Abstract

The present paper on three related issues and their integration Product lifecycle management , Enterprise Planning resources and Manufacturing execution systems. Our work is how to integrate all these in a unified systems engineering framework. As most company about two third claim to have integrate ERP to PLM, ; we still observe some related problems as also mentioned by Aberdeen group. In actual global data sharing, we have some options to also integrate systems best practices towards such objective. Such critical study come with solution by reverse engineering, revisiting requirement engineering steps and propose a validation and verification for the success factors of such integration

Abstract

Requirement it's most critical success or failure factor for system. Enterprise Resource Planning (ERP) one of famous enterprise system and many studies focus on define CSF of it to reduce failing cases of ERP implementation and negative factors affecting not only on implementing company but also on the ERP vendors. Many papers have studied the CSF influence in ERP implementation but very little concern about requirement engineering (RE). This research will fill the gap by providing critical review and develop an approach in software system engineering framework by taking account feedback from stakeholders. This original approach is how to deal with ERP failure through a depth relation related to requirement engineering traceability to CSF in a system engineering view (SOS) based on ANSI EIA 632 standard.

Abstract

This paper is on the issue of assessment of E - Learning systems. The originality of the work is to identify main drawbacks mentioned in the literature and propose a systems engineering framework approach. E - learning is more and more used and mainly in developing countries. A large number of E - learning systems have been developed in the institution around the world. These systems can be assessed using multiple dimensions and c riteria. KSA started implementing the E - Learning since 2002. Although of this evolution up to our knowledge, limited research work have been carried out on assessing such system. In response to this limitation this paper is a preliminary research study tha t attempts to propose the requirements list needed to develop a reliable technique or methodology to evaluate an E - learning system. The contribution of this position paper proposition of a framework for future research as seeing ELearning as a system as a ny other system, and hence the assessment becomes a partial validation of the systems with respect to requirements. Requirements can be criteria of ABET accreditation. The methodology will be based on best practices of systems engineering approach.

Abstract

Requirement elicitation is a very important step in to developing any new application. This paper will examine the culture effect on requirement elicitati on in developing countries. This is a unique research that will look at require ment elicitation process in 10 different parts of t he world including Arab word, India, China, Africa and South America. The focus is how the culture affects (RE) and makes every place has its own practice of RE. T he data were collect through surveys and direct interviews. The results show astonishing culture ef fect on RE. The conclusion is that culture effects deeply the t echnique gets chosen for requirement elicitation. I f you are doing RE in Thailand, it will be very different from RE in Arab world. For example in Thailand re spect for leader is critical and any questioning of manag er methods will create a problem while in Arab worl d decision tree is favourite RE technique because vis ual are liked much more than documents.

Abstract

In the paper process of moving from software requirements to Unified Modeling Language (UML) diagrams has been studied. It shows the importance of this process and discusses many comparative studies in the field. A questionnaire related to the study was distributed worldwide to many research groups, academia, and industry to know the current status of using requirement management tools, knowledge of using UML in software development, frequently used UML diagrams, and the methodology used to generate UML diagrams from requirements. The paper emphasises that there is a need to do some important research in the area of requirements Natural Language processing (NLP) to obtain UML diagrams, and generalize process of using automatic or semi-automatic methodology to generate UML diagrams from requirements.

Abstract

This paper is on Requirements methods and associated tools. It provides general overview of requirement engineering approaches and propose a multi-view approach, and deep comparison on tools and techniques used to manage requirements. The comparison is based on five items, requirement traceability, requirements integration, requirement prioritizing, requirement status, and customer satisfaction. By this comparison it becomes easy to assist the requirement tools and techniques. The paper concentrates on tracing requirement and proposes to develop a model that can be used to handle and manage requirement traceability on large and complex systems.
