Projects that include many complex processes tend to be extremely difficult to managers and staff in terms of shared understanding, analysis, and improvement. Therefore, a new approach is developed to investigate complex processes, such as software development processes, using business process modeling. Particularly, this paper presents an investigation into the use of Role Activity Diagramming (RAD) to model complex processes in the software industry sector, with reference to the process of TestWarehouse. Systematic extension and quantitative analysis to RAD models has led to discover process bottlenecks, identify cross functional boundary problems, and focus discussion about automation of processes. Further research work is being undertaken to replicate this study on other application domains and thus generalize the adopted approach.

Purpose-The purpose of this study is to explore and investigate empirically the relationships between system quality, information quality, service quality, internet self-efficacy, perceived usefulness, intrinsic, user satisfaction, and continuous intention to use e-learning system in Jordan. Motivations-The motivations for conducting this study are: this work has never been done in the Jordanian universities, and most if not all the literature is western-based, and there is dearth of studies that combine all these variables together in one research model. In addition, it is an empirical research where important findings emerge and as a result, relevant practical recommendations are provided. methodology/approach- This study approaches the above purpose by developing a questionnaire build on intensive literature review and consulting existing valid instruments that appeared in prior studies. The original version of the questionnaire was written in English then translated into Arabic. The questionnaire was circulated to all students who have at least one module supplied through university's e-learning system. Findings- The results of data analysis indicate that there is a positive relationship between system quality, information quality, service quality, internet self-efficacy, perceived usefulness, intrinsic, and user satisfaction. Other result also shows the relationships between system quality, information quality, service quality, internet self-efficacy, perceived usefulness, intrinsic, user satisfaction, and continuous intention to use e-learning system. Finally, the results suggest that there is no difference in the evaluation of continuous intention to use elearning systems by research respondents in terms of demographic variables such as, gender, age, and level of education.

This paper presents a new method for deriving system models based on business process models. The congruence between the central notion of ‘automated activity’ in improved RAD model and that of ‘process’ in DFD facilitates the deriving process. This method led to develop system models in early stage which can be used to perform what-if analysis to define the applicability and profitability of the anticipated software system. The process of cancer registration in Jordan is used to demonstrate the proposed approach and showing its ease and timeliness. Finally, further work is planned to validate and evaluate the proposed method using several cases with different domains.

Abstract�Precise identification of current system requirements is crucial for successful legacy system maintenance and re-engineering. Failure to understand the requirements of legacy system indicates that rational choices about how to adapt the software cannot be made. Therefore, a new approach to utilize business process models in evolving legacy systems is proposed in this paper. The proposed approach adopted the extended Role Activity Diagram notation to bridge the gap between business process models and automated systems. This facilitated the reverse engineering of use case models of legacy systems as a basis for further system maintenance and/or re-engineering. The process of cancer registration in Jordan is used to demonstrate the proposed approach and show its ease and timeliness. Finally, further work is planned to validate and evaluate the effectiveness of the proposed approach using a number of legacy systems of different application domains.

A novel process to discover test case patterns is proposed. This has led to the construction of a test case patterns catalogue. The catalogue has been analysed to estimate the potential reusability in different software applications. This has shown that 43% of system functions are generally application domain independent, whereas 57% are application domain dependent. Statistical tests showed that the level of specialisation in software systems could be as low as 20%, which supports the direction taken in this research to reuse test case patterns in software engineering activities, in particular, software cost estimation at the early sages of software development

In this pa1per, a combination of qualitative research methods is utilized to uncover new environmental factors affecting the management of software projects. Two new findings emerged from this study. First, workspace allocation directly affects resources productivity; and consequently, final deliverables of software projects. This effect could be positive, negative, and/or neutral nature. The second is the identification of sub-factors that control the nature of effect of this newly uncovered factor. Hence, a thorough evaluation for the project context should be undertaken to decide on the suitable workspace allocation strategy that will guide it to a safe end. Further work is being carried out to apply the same study on other environments so as to cross validate the results and generalize the conclusions of this research.

This paper presents an investigation into the use of Role Activity Diagramming (RAD) to model complex processes in the healthcare sector, with reference to the process of Cancer Care and Registration in Jordan. We argue that RAD models are generally useful as a means for understanding, analysing and improving complex processes. Also, we show that using these models it is possible to discover process bottlenecks and unvalidated data, to identify cross functional boundary problems, and to focus discussion about automation of processes.

A new approach to perform feasibility studies using business process models is proposed. The utilization of the improved Role Activity Diagram notations has led to the extraction of the number of candidate use cases in software systems which naturally led to software cost estimation much before the availability of detailed system requirements. This enables project managers to perform their what-if analysis to inform the applicability and profitability of the anticipated software system. The process of cancer registration in Jordan is used to demonstrate the proposed approach and showing its ease and timeliness. Finally, further work is planned to validate and evaluate the proposed approach using a number of current software projects.

This paper presents an approach to the identification and inclusion of ‘non-functional’ aspects of a business process in modelling for business improvement. The notion of Non-Functional Requirements (NFRs) is borrowed from software engineering, and a method developed in that field for linking NFRs to conceptual models is adapted and applied to business process modelling. Translated into this domain, NFRs are equated with the general or overall quality attributes of a business process, which, though essential aspects of any effective process, are not well captured in a functionally oriented process model. Using an example of a healthcare process (cancer registration in Jordan). We show how an analysis and evaluation of NFRs can be applied to a process model developed with Role Activity Diagramming (RAD) to operationalise desirable quality features more explicitly in the model. This gives a useful extension to RAD and similar modelling methods, as well as providing a basis for business improvement
