Role of Agile Methodology in Software Development

Five principles of XP are : Simplicity, communication, feedback, courage and quality work of team. But, Extreme Programming(XP) is not suitable for distributed teams. XP support collaborative code ownership i.e. no module is owned by a single person and that is the advantage of XP because it speed up the development process and also helps in detecting errors and faults at coding phase which improve the effectiveness of software. Working of XP is shown in fig 2.

was studied. The main findings indicate that the UPEDU and SCRUM methodologies were presented and the high compliance level with the ISO/IEC 29110 Project Management process. David P. Harvie et al. [9] presented software engineering and mission command was two separate but similar fields, as both were instances of complex problem solving in environments with ever changing requirements. The research hypothesis was that modifications to agile software development based on inspirations from mission command. Targeted Scrum was a modification of Traditional Scrum based on three inspirations from Mission Command: End State, Line of Effort, and Targeting. Martin Tomanek and Tomas Klima [10] introduced the penetration testing was embedded into the scrum framework that represents the most used agile software development framework. The scrum was helped to automate the penetration tests during the software development projects, incorporate the specific penetration tests into the regular software releases and improved the overall resistance of developing software. The research was focused on development of the penetration testing methodology PETA. Bruno Antunes [11] proposed an analyzed waterfall vs. agile methodology that used an agile methodology, scrum. It described a solution approach of a virtual team, as well as shows some examples of using the Microsoft Visual Team Foundation Server tools to address the challenges. Software development environment dictated speed, flexibility and a people centered focus.

A Framework For Software Quality Assurance Using Agile Methodology

A Framework For Software Quality Assurance Using Agile Methodology

2.14) Impact of Agile methodology on Software Development Process (K.Gaurav & K. Pradeep, 2012) A group of methods to develop software focusing on iterative and incremental process are called as Agile Methodologies. It is helpful in achieving high software quality in less time, interaction of customers and less written work. The priority of agile methodology is to satisfy customer, welcome to change requirements and deliver working software frequently. The most commonly used agile methodologies are XP, SCRUM, FDD and Crystal method. Various studies depicts that developing software using agile has great effect on quality and the benefits of agile in software development include: handling change of requirements, fault detection, increased performance, iterative and incremental delivery and improvement in quality. But there are also some limitations of Agile which are main focus on development rather than design, do not scale well to large projects and management overhead is increased. Adopting agile technique has a wide effect on the quality and the productivity of the software. And then, both the customer and the team who is linked with development process becomes satisfied with the work.

amount of documentation. One can observe from third value importance should be given to the relationship between developers and customers over strict contracts. The fourth value refers the members in the team should be prepared to make changes whenever required during the software development life cycle rather than following a plan. Agile methods helps to improve communication and reduce coordination problems in software products. These agile methods are opposite in nature with respect to traditional approaches. When following the traditional approach software is developed in a sequential manner. Requirements are gathered from clients, there is little interaction between clients and members of the development team. For designing and coding different roles are assigned to developers and finally software is tested and integrated. In doing all these ,a large amount of documentation is produced that contains information about developmental processes. Agile Software Development approach aims at overcoming these shortcomings of the traditional approaches.

Applying Agile Software Development Methodology in a Dynamic Business Environment

Applying Agile Software Development Methodology in a Dynamic Business Environment

Abstract:- In a fast changing business environment, companies that can innovate better and faster, and respond quickly to customer’s requirements, will win. One of the most important industries of knowledge-based economy, by all means, is the software industry. In order to achieve business success and to innovate in the market, almost every large organization relies on software. The emergence of Web 2.0 and web-based services have changed radically the way of conducting business as well as the way of building applications. In a web service environment, software applications are becoming services that can be easily linked with other software components, and can provide faster and more productive communication between businesses and customers. The software development companies now need to release products and services more frequently, involve the user participation even as co-developers, and improve the product continuously by receiving real time feedback from the users. In such a dynamic and networked business environment, many companies are adopting Agile software development. There are many reasons for this: agile methods require continuous dialog between business and IT. Fast respond to change and meeting customer satisfactions through early and continuous delivery of the software is also the main goal of agile methodology. The purpose of this work is to find out what are the business benefits of agile methods, and how suitable or valuable is agile development methodology in developing dynamic applications in Web 2.0 service environment. This challenge will be approached as followed: define the Software Development Life Cycle and illustrate some development methodologies, define the Agile Manifesto to clarify the concept of agile software development and Scrum in particular, and discover and analyze the business benefits, agile change and risk management of agile development methods.

Challenges in Agile Software Development

Challenges in Agile Software Development

Software development became main concentration of software developers in the early 20 th century. Different software development processes has been evolved. ASD is the dominating method today, due to its capacity to respond quickly to the changing business requirement. There are several agile development methodologies that will help improve the process in different ways like XP, Adaptive software development, Scrum, Lean development etc. But it also imposes certain challenges. This paper discussed the different challenges involved in various agile methodologies. The challenges are not restricted to particular role. It may be with respect to developer, Customer or project managers or contractors etc. If the organization has not overcome these challenges, that will be a bad threat on their performance as well on the profit and revenue. So, possible solutions to the corresponding to the challenges are discussed.

Software Engineering (9th Edition) pdf

Software Engineering (9th Edition) pdf

As I was writing the final chapters in this book in the summer of 2009, I realized that software engineering was 40 years old. The name ‘software engineering’ was proposed in 1969 at a NATO conference to discuss software development problems— large software systems were late, did not deliver the functionality needed by their users, cost more than expected, and were unreliable. I did not attend that conference but, a year later, I wrote my first program and started my professional life in software. Progress in software engineering has been remarkable over my professional life- time. Our societies could not function without large, professional software systems. For building business systems, there is an alphabet soup of technologies—J2EE, .NET, SaaS, SAP, BPEL4WS, SOAP, CBSE, etc.—that support the development and deployment of large enterprise applications. National utilities and infrastructure— energy, communications, and transport—all rely on complex and mostly reliable computer systems. Software has allowed us to explore space and to create the World Wide Web, the most significant information system in the history of mankind. Humanity is now faced with a new set of challenges—climate change and extreme weather, declining natural resources, an increasing world population to be fed and housed, international terrorism, and the need to help elderly people lead satisfying and fulfilled lives. We need new technologies to help us address these problems and, for sure, software will play a central role in these technologies.

Agile Methodology Adoption: Benefits and Constraints

Agile Methodology Adoption: Benefits and Constraints

Agile practices have recently gained popularity among a large number of companies as a mechanism for realizing early return on investment (ROI) and increasing ability to handle changes in dynamic market conditions. Agility in short means to reduce as much of the heaviness commonly associated with traditional software development methodologies, as possible, in order to promote quick response to changing environments, changes in user requirements , accelerate project deadlines, and the like [1]. Agile methodologies prefer software product development over documentation.

Software Upgradation Model  Based on Agile Methodology

Software Upgradation Model Based on Agile Methodology

In software engineering, the software development model can be either traditional that include waterfall, prototype, incremental models etc or agile software development models that include SCRUM, crystal etc. There exists no such model currently, which dictates how to enhance existing software. In fact, to update existing software to higher level we don’t have any specific model even though the requirement of this type models is very high, especially in this highly dynamic

An ontology of agile aspect oriented software development

An ontology of agile aspect oriented software development

Yet another agile method, Scrum, is integrated with AOP by Wiese [22]. This may be significant in the sense that Scrum does not really impinge on engineering practice in the same way that, for example, XP does. In Weise’s study, AOP impacted on the management of the agile project, because a cross module team was established to take responsibility for cross cutting concerns, supported by common code ownership. Module teams however could ‘spike’ prototype AOP solutions. Published AOP adoption patterns such as Aspect Team pattern and Magic Build System [23] were used. The important role of the AOP evangelist is stressed in the paper, along with strategies for ensuring that aspects do not impact excessively on the overhead of continuous integration. AOP modularizes crosscutting concerns so cross module issues can be handled centrally, supporting Scrum goals. However AOP goes one step further than Scrum. Not only are cross module issues reflected on and designed in a central team but they are also implemented in a central place.

RANKING THE INFLUENCE USERS IN A SOCIAL NETWORKING SITE USING AN IMPROVED TOPSIS METHOD

The Development Method Selection Framework (DMSF) can be used to predict the methodological domain for the project-in-hand by gathering project characteristics in the form software parameters or metrics. Weights are assigned depending upon the role of these metrics on the software development. The process is helpful for the organizations to save on huge losses incurred upon the failure of projects caused due to wrong selection of process models. Proposed framework is supported by the decision support system realized with the help of feed- forward back propagation neural network architecture of artificial neural networks. In the future we intend to improve the selection process using different machine learning algorithms like Random Forest, Logistic Regression and Decision Tree to ensure more accurate and precise results.

on complex projects. Scrum follows a planned strategy as rugby players moves with a good plan. The process of beginning Scrum involves Scrum master and Product owner and core team. First Scrum starts with the preparing of product backlog, by prioritizing the features the release backlog can prepare, it is subset of product backlog. Scrum has the phases of sprint planning meeting, daily Scrums, sprint review and shipping product and finally sprint retrospective and follows the same process for the next sprint [1][5]. Today Scrum has become the leading agile methodology used by the companies globally. The process of agile scrum is shown in below figure 1.

Agile Project Management Managing for Success pdf

Agile Project Management Managing for Success pdf

Given the discussion above, the Agile Manager might ask, “Does this mean virtual teams won’t work?” This is a fair question, as many experts in the fi eld of agile development espouse that true collaboration can only happen if everyone is in the same place. And while this may be preferable, it is not always possible. However, there are ways the Agile Manager can facilitate geographically diverse “virtual teams” and still create, to a great extent, an atmosphere of collaboration and coopera- tion. One methodology that has been used by some organizations is to initially bring the team together for the start of the program/project to facilitate the initial collabo- ration between the team members. This could be for 2–6 weeks at the beginning, depending on the length of the development program/project. Then the team mem- bers return home, but keep in daily contact, either by Video Teleconference (VTC), by Skype, or even by phone. After a given length of time, the team is then reassem- bled, possibly at one of the other locations, and the collaboration rekindled between the teams. This allows them to foster trust and cooperation, to create an atmosphere and feeling of collaboration, even though they are geographically separated. Obviously there are challenges to be overcome with virtual teams, but it is possible, and it’s up to the Agile Manager to keep track of what is going on (not interfere, but observe) and remove any roadblocks encountered so the teams can work effi ciently. The main point of all of this discussion is that the agile development project suc- ceeds or fails, based on the vigilance, understanding, and commitment of the Agile Manager, fi rst to the agile process in general, but also to creating the right team dynamics throughout the agile development life cycle. While the Agile Manager can develop the skills to form and facilitate agile development teams, there are tools the manager will need to provide to the teams so that the collaborations are cap- tured, along with retrospectives, to allow each team member to grow, and so the Agile Manager can review what worked and didn’t work for each program/project. Also, the Agile Manager will need their own productivity and metrics tools to mea- sure progress, effi ciency, and quality of the software development across the Sprints.

An ethnography of multiplicity : Wittgenstein and plurality in the organisation

An ethnography of multiplicity : Wittgenstein and plurality in the organisation

As such, this process will draw light inspiration from the Gioia methodology for structure (Gioia et al., 2012). However, we depart radically from this approach in line with Wittgenstein: Instead of searching for “terms”, we transcribe “significations” verbatim which are pertinent to our topic of investigation. We abandon “themes” and “dimensions”, searching instead for “family resemblances” which aid in populating a “depth grammar”. Rather than going on to generate theory, the aim is to assemble a “surveyable representation” such as this which can serve to highlight “lateralizations” (Maurer, 2005, p. 17; Wittgenstein, 2009, pp. 37, 54-55, PI §67, §122). This process is realised practically using the reference management software “Qiqqa” to facilitate a manual, in vivo coding approach. After an initial reading, the texts are scoured for any talk or action which plays a role in language games around “agile”. These “significations”, illustrative examples of language in use, are highlighted in-text on this second pass reading. The next stage in the analysis is the identification of “family resemblances” between the significations; these are analogous to the “themes” discussed by Gioia et al. (2012). Once apparent connections between the significations have been identified, the in-text annotations are tagged in Qiqqa with the appropriate resemblances. This allows for the production of reports which can be filtered via tags to collate all significations which resemble one another in the role they play in the agile “language game”. These reports enable the final stage in the analysis; the development of a “depth grammar” for the observed language use. This revolves around drawing out multiple distinct groupings of shared usage patterns within these similar significations. Returning again to the language of Gioia et al. (2012), we are distilling the “aggregate dimensions” from the themes. The end result is a picture of the observed meanings in operation around the concept in question. However, these findings are not presented in summary form as with Gioia et al.’s (2012) data structure. Rather, the depth grammar informs the creation of a narrative account, the “surveyable representation”. The researcher explores the relevant significations verbatim to allow for the conveyance of more than reified analytical conclusions to the reader. Emulating Maurer and Wittgenstein, the hope is that, while remaining alive to our own “warping” influence, we can effectively act as a prism; refracting (not truly reflecting) overlaps,

Android Application Development for Social Network

Android Application Development for Social Network

The main reason behind selecting the Agile method is the simplicity of this strategy which is rapid development without too much need of documentation in case of the android application we need to build, check, correct, rebuild, test continuously and every time we make changes we need to go through these steps to verify the results of our work. Agile methodologies including programming, development and project management involve simplifying the software development into small modules, while combining documentation and quality testing at every step. The regular waterfall methodology includes judging the requirements ahead of time with testing and documentation as end steps rather than being the crucial part of development. This methodology provides improvement techniques that are effective and profitable for portable applications advancement.

A Review of Risk Management in Different Software Development Methodologies

A Review of Risk Management in Different Software Development Methodologies

Different software development methodologies exist. Choosing the methodology that best fits a software project depends on several factors. One important factor is how risky the project is. Another factor is the degree to which each methodology supports risk management. Indeed, the literature is rich in such studies that aim at comparing the currently available software development process models from different perspectives. In contrast, little effort has been spent in purpose of comparing the available process models in terms of its support to risk management. In this paper, we investigate the state of risk and risk management in the most popular software development process models (i.e. waterfall, v-model, incremental development, spiral, and agile development). This trend in such studies is expected to serve in several aspects. Technically, it helps project managers adopt the methodology that best suits their projects. From another side, it will make a way for further studies that aim at improving the software development process.

Human centered software development methodology in mobile computing environment: agent supported agile approach

Human centered software development methodology in mobile computing environment: agent supported agile approach

Firstly, the MCE is different from the conventional computing environment. The lifespan of mobile software is quite dependent on the usability, and this usability is also dependent on the user requirements. Requirements from mobile software users are variable and capricious. Thus, if we want to make a long-term mobile application on the MCE, it is critical to reflect and satisfy the dy- namically changing requirements. Also, the accuracy of processed information for adaptation is important. The MCE has limited resources, including memory, battery, and display. Therefore, developers are required to con- sider these limited resources. These differences and re- strictions make the conventional software development methodology inapplicable for the mobile software devel- opment. The additional requirement of adaptation also pulls variable cases and variants, which should concern the developer. In other words, the applications in the MCE need to be more intelligent. They need to re- cognize the dynamically changing environment and properly react to those changes. To develop such appli- cation, the conventional development methodology is not sufficient. Therefore, some labor- and knowledge- intensive processes and complexities exist in the back- ground of realizing adaptation, and this is why the novel development methodology is proposed in this paper.

INFORMATION TECHNOLOGY FOR NUMERICAL SIMULATION OF CONVECTIVE FLOWS OF A VISCOUS INCOMPRESSIBLE FLUID IN CURVILINEAR MULTIPLY CONNECTED DOMAINS

It is clear that no single method is able to perform tasks for all projects [21, 44]. However, the project manager(s) must determine the nature of the project, and after that, the best appropriate development methodology is selected [21]. According to McCauley [45], both process-oriented and agile methods are significantly required since there is no one-size-fits-all development paradigm, which can be appropriate with the whole conceivable purposes. This view is common through many specialists in the field [46]. The principal aspects of agile and light methods comprise speed and simplicity. Hence, the development group just focuses on functions that are required within the development work, rapidly delivering them, gathering feedbacks and responding to the information that is being delivered. What lets a development methodology be an agile one? The case is based on a software development that is cooperative (developers and customers who are continuously working all together with close communications), incremental (small software releases with short iterations), adaptive (the ability of the method to produce last moment changes), and straightforward (the methodology is well documented, simple to learn, and easy to be modified).
