Monitoring oriented agile based web applications development methodology for small software firms in Jordan

Small software firms (SSF) is vital to the software industry in many countries as they provide substantial growth to their economy. In Jordan, most software companies that are involved with developing Web applications are small firms. However, the extent of applying best Web applications development and management practices in these firms is limited. Besides, the existing software development methods are still lack of monitoring the quality of process and product. As a result, the Web application being developed exceeds deadlines and budget, and not meeting user requirements. Therefore, this research aims to construct a new methodology referred as Monitoring Oriented Agile Based Web Applications Development (MOGWD) Methodology for SSF. This study introduced an Extended Agile Method by extending the Scrum method with Extreme Programming (XP) elements. The Extended Agile Method was improved by combining common steps of Web design method and incorporating the Goal Oriented Monitoring Method (GOMM). The GOMM has defined twenty goals. Each goal has one or more questions. The questions are answered through the defined metrics. There are 101 qualitative metrics for monitoring the process quality, and 37 quantitative metrics for monitoring the process and product quality. Moreover, the proposed MOGWD methodology defines four phases: Plan, Do, Check and Act. The MOGWD methodology was evaluated using expert review and case study. The evaluation results show that the MOGWD methodology has gained SSF practitioners’ satisfaction and found to be practical for the real environment. This study contributes to the field of Agile based development and Web applications measurement. It also provides SSF practitioners a development methodology that monitors the quality of the process and product for Web development

The role of transparency and trust in the selection of cloud service providers

PhD ThesisPotential customers started to adopt cloud computing because of the promised benefits such as the flexibility of resources and most importantly cost reduction. In spite of the benefits that could flow from its adoption, cloud computing brings new challenges associated with its potential lack of transparency, trust and loss of controls. In the shadow of these challenges, the number of cloud service providers in the marketplace is growing, making the comparison and selection process very difficult for potential customers and requiring methods for selecting trustworthy and transparent providers. This thesis discusses the existing tools, methods and frameworks that promote the adoption of cloud computing models, and the selection of trustworthy cloud service providers. A set of customer assurance requirements has been proposed as a basis for comparative evaluation, and is applied to several popular tools (Cloud Security Alliance Security, Trust, and Assurance Registry (CSA STAR), CloudTrust Protocol (CTP), Complete, Auditable, and Reportable Approach (C.A.RE) and Cloud Provider Transparency Scorecard (CPTS)). In addition, a questionnaire-based survey has been developed and launched where by respondents evaluate the extent to which these tools have been used, and assess their usefulness. The majority of respondents agreed on the importance of using the tools to assist migration to the cloud and, although most respondents have not used the tools, those who have used them reported them to be helpful. It has been noticed that there might be a relationship between a tool’s compliance to the proposed requirements and the popularity of using these tools, and these results should encourage cloud providers to address customers’ assurance requirements. Some previous studies have focused on comparing cloud providers based on trustworthiness measurement and others focused only on transparency measurement. In this thesis, a framework (called CloudAdvisor) is proposed that couples both of these features. CloudAdvisor aims to provide potential cloud customers with a way to assess trustworthiness based on the history of the cloud provider and to measure transparency based on the Cloud Controls Matrix (CCM) framework. The reason for choosing CCM is because it aims to promote transparency in cloud computing by adopting the best industry standards. The selection process is based on a set of assurance requirements that, if met by the cloud provider or if it has been considered in a tool, could bring assurance and confidence to cloud customers. Two possible approaches (Questionnaire-based and Simulation-based approach) are proposed in order to evaluate the CloudAdvisor framework.Ministry of Higher and Education in Saudi Arabi
