The quality of software is an important topic in the development of successful software application. Many software development methods have been applied to enhance the software quality. The improvement of software quality can be achieved through using refactoring which improves the internal structure of a software without changing its external behavior. However, refactoring effects the quality attributes of software such as reusability, complexity, maintainability, flexibility, modularity, modifiability, and understandability. Thus, there is a need to proof the imprint of refactoring on the software quality. This paper will propose a software development model under the refactoring method concept. In addition, an evaluation will be conducted to check the effectiveness of the reusability and modifiability quality attributes on a software development process with and without applying the refactoring method. As a result, this study can be used by developers to aid them in determining whether to apply refactoring to improve quality attributes.

There are thousands of teams that are using the Scrum. But few of them are really “living” Scrum and achieve the success of their projects. This paper discusses the factors that lead the Scrum team to be successful. This paper introduces some important previous works related to the success factors in agile projects; especially that related to the Scrum teams. Then, the researchers extract a list of most effective success factors of the Scrum team. The researchers put the gathered success factors in a form of a questionnaire and passed it to 70 respondents to extract the importance degree of every success factor. Only 57 respondents provide the researchers with complete answers. Depending on the results, the success factors of the Scrum team are categorized according to the importance degree. This paper highlighted the most important success factors that must be considered by Scrum teams when developing a software project.

Software has become part of all aspects of our lives, and organizations are increasingly conceiving extremely large and complex software projects. Software industry has an option to choose suitable methodology/process model for its current needs to provide solutions to give problems. According to some researchers, a hybrid approach can help optimize the software development lifecycle by combining two or more methodologies. eXtreme programming (XP) and Scrum are most widely practiced and documented agile models. Both XP and scrum work well for small projects whereas Rational Unified Process (RUP) is suitable for large projects. This paper analyzes characteristics, strengths, and weaknesses of both conventional and agile methods. This paper also explains the four major phases and nine disciplines of the RUP, XP and the common elements of the Scrum process. Finally, this paper suggests a new hybrid software development method that combines the RUP with XP and Scrum process to accommodate the strengths of both methods while suppressing their weaknesses to get high quality and improve the team productivity. The hybrid method can be utilized in the software industry, particularly, in the business sectors that deal with large-scale projects.

Requirements elicitation is an important phase of the requirement engineering process. A complete and accurate collection of user requirement can reach to the success of the project. This paper studied and discussed the success factors of requirements elicitation task. First, some important previous works related to the requirement elicitation process are presented. Then, the researchers extract a list of most effective success factors of the requirement elicitation. A new list of the collected success factors is proposed that includes two dimensions; success factors should be considered before beginning the requirement elicitation process, and success factors should be considered during the process.

In software engineering, there are a variety of methodologies or methods for developing and managing software projects. These methodologies can fall under two main categories: agile and classical. There is no methodology that is appropriate for all situations. It is advisable to combine these methodologies to strengthen their throughputs while reducing their weaknesses and limitations. However, the literature has shown that there is a lack of studies that address the problem of combining two or more methodologies to software development and management. In this paper, the researchers propose a systematic approach that shows how to flexibly build new hybrid methodologies based on their metamodels. Metamodeling provides a formal specification that allows for developing tools that support the use of the new hybrid methodology.

Nowadays, Volunteered Geographic Information (VGI) becomes an important source of massive citizen-generated Geographic Information (GI) datasets. VGI not only creates new GI datasets, it enriches the existing authoritative datasets as well. Furthermore, in some contexts where authoritative datasets is not available, VGI may be the only source of GI. Although, VGI possess numerous advantages, it unfortunately faces several challenges. One of the clear challenges that face VGI is the quality. VGI quality is inherently heterogeneous and VGI lacks quality assurance. Due to its different nature, VGI does not comply with standard quality assurance procedures that are applied to spatial data. Thus, assuring VGI quality becomes increasingly important. Various previously proposed studies are concerned with VGI quality assurance. This paper conducts a literature review on previously proposed VGI quality assurance mechanisms. The paper discusses each mechanism and its limitations. A comparison between all proposed mechanisms is conducted as well.
