Scrum of scrums is an approach used to scale the\ud traditional Scrum methodology to fit for the development of\ud complex and large projects. However, scaling the roles of scrum\ud members brought new challenges especially in distributed and\ud large software projects. This paper describes in details the roles\ud of each scrum member in scrum of scrum to propose a solution\ud to use a dedicated product owner for a team and inclusion of\ud sub-backlog. The main goal of the proposed solution is to\ud optimize the role of product owner for distributed large projects.\ud The proposed changes will increase cohesiveness among scrum\ud teams and it will also eliminate duplication of work. Survey is\ud used as a research design to evaluate the proposed solution. The\ud results are found encouraging supporting the proposed solution.\ud It is anticipated that the proposed solution will help the software\ud companies to scale Scrum methodology effectively for large and\ud complex software projects

Cloud computing as a new paradigm has\ud grown from a promising idea to one of the fastest\ud research and development paradigm in education sector.\ud It is a hot research area that applies in all sectors where\ud we require high performance and fast access to resources\ud and services. Cloud computing usability in education is\ud wide-ranging, as acknowledged by many educational\ud institutions around the world. This paper attempts to\ud address the need for utilizing cloud computing in higher\ud education in Kingdom of Saudi Arabia for all the\ud disciplines to raise its level and solve the obstacles that\ud faced the learning process. In addition, cloud computing\ud facilitates educators and students to be more experienced\ud in cloud computing and it prepares them to get benefits of\ud usefulness to become more motivated and effective.\ud Survey is used as a research design to validate the\ud proposed solution. The results show that the proposal to\ud improve higher education is highly supported by the\ud professionals working in the industry and academia

A new approach, to measure normalization completeness for conceptual model, is introduced using quantitative fuzzy functionality in this paper. We measure the normalization completeness of the conceptual model in two steps. In the first step, different normalization techniques are analyzed up to Boyce Codd Normal Form (BCNF) to find the current normal form of the relation. In the second step, fuzzy membership values are used to scale the normal form between 0 and 1. Case studies to explain schema transformation rules and measurements. Normalization completeness is measured by considering completeness attributes, preventing attributes of the functional dependencies and total number of attributes such as if the functional dependency is non-preventing then the attributes of that functional dependency are completeness attributes. The attributes of functional dependency which prevent to go to the next normal form are called preventing attributes.Comment: 8 Page

Many software development companies faced the challenge of coupling agile models and global software development in distributed projects. The challenges are related to the communication, management and control of the development process. These challenges emerged because global development involves developers from different geographical locations, time zones and with different cultures. Coupling agile models and global software development seems impossible at first glance, as they require frequent communications, rapid development, and resources management of distributed teams. However, researchers proposed several solutions and advices included tailoring of agile practices and addition of non-agile practices. Nevertheless, further efforts were needed to activate and unify these solutions. This paper introduces a new web based project management system for Scrum projects called global scrum management. It is a web application that manages Scrum process from planning phase to delivery of the last product increment. Moreover, the application features social networks functionalities to provide seamless communication, collaboration and knowledge transferring to the distributed team members. Also, developers' actions to the sprint tasks, including updating task status, will be reflected to the burn down charts of the sprint and product backlog instantly. Several diagrams are provided in this paper to explain the solution including UML diagrams.

IT companies are facing many difficulties and challenges when dealing with big data. These difficulties have surfaced due to the ever-expanding amount of data generated via personal computer, mobile devices, and social network sites. The significant increase in big data has created challenges for IT companies that need to extract necessary information and knowledge. Cloud computing, with its virtualized resources usage and dynamic scalability, is broadly used in organizations to address challenges related to big data and has an important influence on business in organizations. Furthermore, big data is changing the way organizations do business. This paper proposes novel cloud architecture to decrease problems related to big data. The proposed architecture is a combination of many big data infrastructures in the creation of a service. This architecture minimizes problems related to big data by improving performance and quality of service.

Software engineering (SE) field is considered as a backbone of software industry. Students suffer many problems and difficulties when they approach to industry due to the old contents of SE course, lack of practice and inability in the subject area. The main reason of the SE course problems is the lack of coordination or gap between software industry and academia. This paper proposed a novel solution to enhance SE curriculum to bridge the gap between industry and academia. The proposed solution will assist students at optimal level in their professional careers to achieve goals of SE course. Survey research methodology is used to evaluate the proposed solution and the results of data analysis are highly encouraging. It is anticipated that the universities will find this research helpful to improve the quality of SE course.
