Title Abstract Action(s)
BOUNDARY LINES OF FUNCTIONAL AND NON-FUNCTIONAL REQUIREMENTS FOR SMALL SCALE APPLICATIONS The software development is referred as challenging task in various aspects. The first challenge is to understand the nature of the software package itself. As compared to other engineering disciplines, the computer program item isn’t significant and does not fulfill any corporeal laws which makes it depend on great practice instead of a fundamental theory. Disappointment comes when ventures exceed the allotted budget, require extra time or need vital functionality. Investigations has proved that the dynamic reason of project failure is the insufficient dealing with the requirements, the major agenda of the project must be fulfilled accordingly. The first and the foremost need in designing any software system is to develop the basic specifications of the software. Such specifications explain customer requests, where typically customers convey their needs in a natural language or in a written narration of the software system they want. Need of high-quality software specifications is a critical success factor, as any defects in the requirements will have a detrimental impact on the overall development process and result in high costs to fix them. This research basically educates us regarding the characteristics of the functional and nonfunctional requirements, and develops the boundary lines to segregate the requirements for small scale applications. After reviewing the literature critically, a framework is proposed which is able to help in classification of functional and non-functional requirements.
SOFTWARE PROJECT MANAGMENT APPROACH FOR REDUCING RISK IN GLOBAL SOFTWARE DEVELOPMENT PROJECTS Within the last several years, Global Software Development (GSD) has a significant impact on the business and software industries. Many software development companies enjoy the benefits of GSD, including cost reduction, cheap labor, and skilled workers around the clock, but these companies also posed some problems because of GSD. These problems affect the long-term survival of GSD projects. One of the GSD's major problems is communication amongst the various team members of the companies. As a result, the purpose of this research is to determine the communication issues that can affect on GSD and propose a mitigation strategy for the solution of the identified communication issues A systematic literature review (SLR) is carried out to determine communication issues in GSD, and then a mitigation strategy is proposed as a solution to these problems. After that, an online survey is conducted to validate the communication issues that can effect on GSD finds through SLR. Then a focus group conducted to validate the mitigation strategies that can be given for communication issues. The results of our research are to be helpful for GSD based companies in context of communication related issues. Our research is to be fruitful for the researchers that can find the solution of communication related issues in GSD.
IDENTIFICATION AND MITIGATION OF CHALLENGES IN MACROTASK CROWDSOURCING Crowdsourcing has become an evolution in which tasks are outsourced by open call format to large numbers of people to utilize collective intelligence. Macro-tasking crowdsourcing is used to resolve various complexities with different degrees of disintegration, assumes different expert level of knowledge in one or even more fields, and integrates adaptable. Processes for work management involving crowd involvement. Crowdsourcing should identify macro-tasking for tackling more complicated problems. Macro tasks could be defined as complicated multitasking that is often decomposable to micro tasks, though not always. Macrotask crowdsourcing has many advantages in every step of the software development life cycle due to its diversity of crowds, faster problem solving and significant cost savings but at the same time, there are many risks involved. Which affects the success of crowdsourcing in software development life cycle. In this search first of all we will identify all the challenges macrotask crowdsourcing through systematic literature review from the literature and then we will propose the mitigation plan to mitigate the challenges that causes the harm to the macrotask crowdsourcing system and approaches to prevent these challenges achieve goals of software macrotask crowdsourcing. We will use the mixed methodology of systematic literature review, qualitative and quantitative analysis to get our results. Systematic literature review will be used to identify the challenges of macrotask crowdsourcing and then we will confirm it from industry by doing the survey and then we will do the focus group to verify it from the experts. Our results will identify the challenges that causes the harm to software crowdsourcing and the mitigation plan to remove them to achieve the maximum results for macrotask crowdsourcing. Our research will cover the gap of identification of challenges of macrotask crowdsourcing and its mitigation plan to help all the stakeholders in the industry to achieve maximum results in the macrotask crowdsourcing projects. In the future phase we will implement these mitigation strategies in the industry .
THE MARGINALIZING DIFFERENCE AMONG CUSTOMER’S NEEDS AND EXPECTATIONS Software engineering is defined as a process of analyzing, understanding the user requirements, and then designing, constructing, and testing the software product according to user requirements. The requirement elicitation is the foundation and first activity of the software development process. During the elicitation phase, we face several issues related to customer needs and wants. Our research aims to marginalize the customer’s needs and expectations. To identify the gap,we take an example through a literature review. First, we classify the gaps in the literature with support of a systematic literature review(SLR). We identify all high values possible gaps from literature. After that, we survey different software organizations .basically we used a mixed-method methodology to minimize the gaps. The mixed methodology will be used to minimize the gap between customer’s needs and wants. In mixed methodology, we used qualitative analysis and quantitative analysis. The validation takes place under the triangulation process. The triangulation process is based on both qualitative analysis and quantitative analysis. After the triangulation process, we proposed a framework to reduce the gaps between customers' needs and wants. Through framework give all possible high values solutions that are discussed in a different journal paper. We merge all possible high-value solutions in our framework. Our contributions are to minimize the gap between customer’s needs and expectations.
A FRAMEWORK FOR REQUIREMENTS CHANGE MANAGEMENT IN DISTRIBUTED AGILE DEVELOPMENT Requirements engineering (RE) is a salient phase in any software development project. Requirements keep changing in today’s software industry due to increased size and complexities. Therefore, an efficient requirements change management (RCM) process is vital for the success of any project. Distributed software development (DSD) has become a norm now and agile methods are being widely used in DSD to counter changing requirements. Agile methods and DSD, being opposite in nature to each other, present new challenges when they are incorporated together in distributed agile development (DAD). Therefore, an efficient RCM process is the need to today’s software industry. This research study has been conducted to fill this gap by presenting a framework for RCM in DAD. Systematic Literature Review (SLR) has been conducted to identify influencing factors that affect RCM process. Grounded theory is then applied for the analysis to categorize the resultant influencing factors. The resulting categories and the influencing factors for each category have been validated through expert review. After the expert review, a survey is conducted to prioritize the results according to their significance during the RCM process. Finally, a framework has been proposed to conduct the RCM process in DAD based on the prioritized categories and their prioritized influencing factors. The study concludes that RCM is vital for successful DAD projects and the proposed framework provides a systematic and scaled solution to conduct the RCM process in an effective manner. The application of proposed framework at a wider scale in the industry is a potential future work of this research study. Automating the framework is another interesting dimension for the future.
MANAGING HUMAN FACTOR IN PROJECT MANAGEMENT FAILURE The objective of any computer program advancement extend is to convey the program item on time, inside the concurred budget, and with the capabilities anticipated by the client. Shockingly, this objective is seldom accomplished. Understanding human components in program advancement, on the other hand, might offer assistance colossally in coming to this goal contribution. Overview of human coordination challenges that affect software development are presented in this thesis. Everyone wants their project to succeed, but not everyone succeeds. Similarly, because the best-trained managers are not always the most effective, some project managers are regularly more successful than others. Project success and failure are determined by the people who make up the project team. When only one person is involved in a project, it is simple, but when working on a long-term project, scientific principles and methods for software development are required, more people will be involved that straight away leads to project failure as Software failures are caused due to bugs, ambiguities, oversights and is interpretation of software projects. In this research thesis the failures caused by human factor, identifying all the human factor and then managing human factor by identifying gaps and giving mitigation guidelines will be identified. Failure in software project management has also been highlighted as being dependent on team makeup, team communication, and management team role.
IMPACT OF TEAM WISDOM ON SUCCESSFUL COMPLETION OF SOFTWARE PROJECTS IN GLOBAL SOFTWARE DEVELOPMENT Global Software Development (GSD) becomes more popular due to the involvement of diverse team members around the world. This diversity creates huge impact on successful completion of GSD projects. Team wisdom in GSD works best to assess the impact of this diverseness. Team wisdom can be conceptualized as multifaceted process to measure the knowledge stock of team members. It is also helpful to utilize that knowledge in decision making of GSD projects. A lot of research has been done in the context of team wisdom but there is lack of research on how team wisdom mechanisms effects successful completion of GSD projects. The aim of this study is to identify the software team wisdom mechanisms and their impact on successful completion of GSD projects. Systematic Literature Review (SLR) was conducted to identify team wisdom mechanisms. 31 out of 564 studies were selected for SLR. A detailed review of these studies was performed by following SLR protocols. Extracted results were analyzed by frequency analysis process. Team wisdom mechanisms: team networking, team diversity, team experience, team prudence, professional ethics and joint-epistemic actions were identified from the literature. Team experience, team networking and team diversity got the highest frequency from SLR. To find the impact of identified team wisdom mechanisms on successful completion of GSD projects, an interview approach was used. Semi structured interviews of eight GSD experts were conducted. Interview transcripts were analyzed by thematic analysis. Team experience and team networking were identified as the most effective team wisdom mechanisms in GSD context. Team diversity, team prudence and joint epistemic actions were considered to be the effective and professional ethics was defined as moderate team wisdom mechanism in GSD. Furthermore, the results of thematic analysis were validated through member checking process. GSD experts found these team wisdom mechanisms helpful in successful completion of software projects in global software development.
