ScrumSpiral: An Improved Hybrid Software Development Model

2014

Scrum, an A gile method has been a topic of much discussion among today"s software industry people and professionals. Unlike many other software development and management processes, Scrum is a framework that favors an iterative and incremental approach. Scrum methods were broken by keeping changing requirements of the clients in mind, and so Scrum has not only supported the adaptation of late requirements in software development but also supports selforganizing manner of work. As scrum seems so fruitful, in this paper authors done a review on Scrum for finding out the current working and adaptations in Scrum implementation and this paper will be an add on literature for other professionals interested in Scrum and agile methods development.

Scrum is the result of evolution in product development originating from the Japanese management system and process improvement (kaizen) and the Toyota production system from middle of the 20th century. However, Scrum is not the end result but a constant evolution. The purpose of this paper is an attempt to add new knowledge to this evolution. There are numerous alternatives to Scrum process and rules, commonly called hybrids. It is important to be aware that one approach or process cannot be a solution for every software development project. The key is to find a balance between the processes and the people, policies and the principles, as well as focus on long-term or short-term goals, etc. This problem is one of the biggest challenges widely discussed in present-day scientific and industrial communities.

Scrum is a part of agile software development which also called incremental software development model. Scrum methodology commonly used to overcome uncertain condition and tight deadline. Scrum consists of three roles, they are product owner, development team, and scrum master. Scrum can be implemented on many areas such as development of education mobile application, integration of document management system, strengthen IT development centers, and many others. The successful of Scrum implementation depends on the skill and knowledge of the team members. The Scrum also has several risk factors and therefore needs risk management approaches. A comparison between agile and waterfall model is also discussed. The Scrum performance can also be tested with certain ways. Scrum used to make sure that all parts of the software can be delivered on time. The other benefits, scrum can make creative and productive workplace, and scrum can also increase business value.

Nowadays, carrying out a project management is difficult in any situation, even more in global projects of software development, whose environment faces different aspects that make this type of projects even more difficult to manage, for example: lack of coordination, lack of face to face communication, temporary differences, cultural diversity and application of different standards, models and approaches. With the aim of supporting agile global software development (AGSD) project management when multiple models are present, we have defined Scrum+, which is a guide based on Scrum and defines a set of activities, tasks, roles and criteria to support AGSD projects in multimodel environments. We carried out the harmonization of agile approach Scrum along with project management practices defined in multiple models such as: ISO/IEC 15504, ISO 9001 and CMMI-DEV. Likewise, the evaluation of the proposal has been conducted through: (i) its application in a focus group with experts in different related areas and (ii) its assessment of the degree of agility by means 4-DAT method. Based on the analysis of the results and the comments obtained in the focus group, Scrum+ seems to be clear, adequate, and agile. The guide proposed here can serve as reference for studying further aspects related to agile software scaled projects.

Software Development Methodologies (SDM) are used for every activity performed on a software product from initiation to maintenance. There are a variety of software development methodologies (waterfall, spiral and iterative) that are available to develop software products. One of the key challenges faced by the software developer is the selection of SDM in a software product. No single methodology is ideal to work effectively in all scenarios. Therefore, software product features play an important role in the SDM selection. This paper aims to explain different features, characteristics, critical practices, advantages, disadvantages of different methodologies related to the software product. We have used six models including waterfall, unified process, spiral, extreme programming, scrum, and feature-driven development. This paper also summarized the limitations and cost control factors of SDM while developing software products.

Agile software development methods, including Scrum, Extreme Programming (XP), and Dynamic System Development Method (DSDM) have been mainly applied to small-scale and dynamically evolving software development projects (e.g., Internet and Web software development) with some success, due to their lighter and faster development life cycle. However, there has been very limited evidence of the effectiveness of such methods (in particular Scrum) in mission-critical and largescale softw are development projects. This pape r w ill present the findings of a case study on the applicability and effectiveness of Scrum in such projects. We first briefly summarized the findings on what aspects of Scrum were both successfully and poorly adopted (applicability perspective) and what aspects of Scrum were key factors to improve or deteriorate the quality of the products in terms of bug rates, development time and costs (effectiveness perspective). Based on literature reviews of small group research, we also analyzed the effectiveness of Scrum from the perspectives of social facilitation, social loafing, and group motivational gains. In addition, we identified five core characteristics of Scrum and analyzed the relationships among them. Finally, this paper provides some suggestions to help organizations overcome obstacles expected in adopting the Scrum method as a future development tool.

Traditionally, software development processes have relied on the use of the "Waterfall" and "Vee" models. Later, Agile methodologies were used to handle the challenges of managing complex projects during the development phase. Agile methodologies are a group of incremental and iterative methods that are more effective, and have been used in project management. Kanban and Scrum are two powerful Agile project management approaches in software development. The objective of Scrum and Kanban is achieved by optimizing the development process by identifying the tasks, managing time more effectively, and setting-up teams. A review of the literature reveals that there is a lack of statistical evidence to conclude which methodology is more effective in dealing with the traditional project management factors of budget handling, risk control, quality of the project, available resources, having clear project scope, and schedule handling. This research statistically compares the effectiveness of the Scrum and Kanban methods in terms of their effects on the project management factors for software development projects. Numerical analysis is performed based on survey responses from those with experience in the Scrum and Kanban methods. Results suggest that both Scrum and Kanban lead to the development of successful projects, and that the Kanban method can be better than the Scrum method in terms of managing project schedule.

To maximize the performance, companies conduct a variety of ways to increase the business profit. The work management between one company and the other company is different, so the differences in the management may cause the software to have a different business process. Software development can be defined as creating a new software or fixing the existing one. Technology developments led to increasing demand for software, Industrial Technology (IT) Companies should be able to project well maintenance. The methodology in software development is used in accordance with the company's needs based on the SDLC (Software Development Life Cycle). Scrum method is a part of the Agile method that is expected to increase the speed and flexibility in software development project management.

Now a days most of the software companies are able to produce valuable software in a very short span of time with minimum costs and with adjustable environments. For this purpose Agile Methodologies were thus introduced to meet all the requirements of a software development company. In this paper we will discuss the agile technique and SCRUM there advantages and disadvantages. Also we discuss about the dissimilarities and similarities between the new requirements of the software development companies.

The aim of our paper is to describe the experience we have using Scrum for agile software project management in a university environment. The paper is divided into three parts. In the first part an overview of the Scrum method is given. In the second part we describe how we used Scrum during the development of (a part of) the student records information system at the University of Ljubljana. Finally, the advantages of Scrum are summarized.
