Disadvantages Of Agile Software Development

Less custom code require less upgrades efforts, and less upgrade effort are less operational costs.

Abstract: Agile software development is a conceptual framework for software engineering that promotes development in iterations throughout the life-cycle of the project .Software developed during one unit of time is referred to as an iteration, which may last from one to four week Scrum is part of the Agile movement. It is a lightweight process framework for agile development. The Scrum method is most often used to manage complex software and product development, using iterative and incremental practices. And results have been shown about significantly increase in productivity and reduces time to benefits relative to classic “waterfall” processes. But scrum method also have some problems and to overcome the problems a new approach is proposed

Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders [1].

+ Customers have better understanding of quality, benefits, and cost of the product by showing the value of the product.

In the early days of software development, it was not uncommon for months to pass before any development began, and once development started, it could be months or years before any type of finished product was ready for testing. The requirements definition and gathering process was often very long, and in many cases the development team was isolated from the customer.

The cost of changing program doesn’t change over time as extreme programming follows some of the practises like getting feedback from customers, coding and testing frequently and eliminating defects early, and Involving customers in every stage of development

In this paper, Rapid Application Development (RAD) and the Agile Development Method (ADM) are compared and contrasted. The paper begins with a summary of each of the articles referenced on the title page, including the pros (benefits) and cons (risks) of each method. The paper then addresses how the two methods might be applied to my company, Parametric Technology Corporation (PTC), an enterprise software solutions provider headquartered in Needham, MA, with about 6,000 employees in over 70 offices worldwide. Finally, the paper concludes with my views on which of the two methods would be more valuable in a development setting. The authors of the article, “Risks of Rapid Application Development,” open by cautioning that software development includes – or should include – more than the speed at which an application is delivered, identifying maintainability and reusability as equally important characteristics. The purpose of the article is to fill a gap in the literature (at the time of the writing of the article) about the long-term implications of RAD tools on both the software itself and the organizations and developers who use it. The authors emphasize that the choice to use RAD is not just a capability decision, it is also a human resources management decision. In addition to a much faster development lifecycle, RAD tools also include requirements planning, design and modeling, code writing, and testing, with the requirements and design phases accounting for about 30% of

Ever since the Agile Manifesto came into existence in 2001, it has led many agile software development processes to spurt up. Dynamic Systems Development Method (DSDM), Extreme Programming (XP), Feature Driven Development (FDD), SCRUM and Crystal Methodologies are some of the most famous agile software development methodology famous today (Vlaanderen et. al, 20011), (Dingsøyr et. al, 2012). In the recent research done by (Dingsøyr et. al, 2012), it’s been found that XP and scrum are the two most common agile methodologies used currently. In their empirical research (Dingsøyr et. al, 2012) also found that most of the existing studies on agile methodology focus on XP and there are very limited studies done on SCRUM. The purpose of this literature review research is to analyze the existing research available on SCRUM methodology. This literature review will provide a broad overview on various information researchers are providing on agile software development methodology, keeping Scrum agile methodology in the focal point. In addition, this literature review will also address the advantages and disadvantages of SCRUM agile methodology. This research will help the audience to gaze over the recent study over scrum and will help in making the decision whether Scrum is the right agile methodology for their software development project.

Agile methodologies provide businesses with a way to quickly react to changes in their environment. By delivering small portions of code over the course of a few weeks, developers can provide end-users with useable functionality on an ongoing basis as they move closer to the goal of providing the complete software. By being more reactive to changes, such as new requirements or changes in priority, agile allows development teams to be able to be more responsive and to provide customers with revised applications that are based on feedback that they have previously provided. Agile models, such as XP, are geared towards cost savings

In order to implement a new feature the developers need to lose only the work of a few days, or even only hours, to roll back and implement it. Close, daily cooperation between business people and developers. Regular adaptation to changing circumstances.

The article also covered the “Manifesto for Agile Software Development,” which was an outcome of an event held in 2001. The “Manifesto for Agile Software Development” is basically a set of values and principles that software developers came up with from that event that should help themselves and others improve the ways of developing software. At the end of the article there is a list of the principles that make up the Manifesto for Agile Software Development. The author also covered why Agile is becoming more favorable in regards to the software being delivered in the form of a service and less of a good. He also explained the roles that the licensee and licensor played in the way that the Waterfall Method software was delivered and updated. In addition, he compared it to the way Agile has changed software into more of a service that is conducted over the Internet. This article also covers in a brief paragraph the purpose of a development agreement and some terms that can be included in it to help both parties. Even though these development agreements can provide great uncertainty and high risk allocation, attorneys can use some features of Agile to help with managing those problems, instead of, being opposed to the development of Agile projects. Now in the article, An Excursion to Software Development Life Cycle, the author focuses more on the different stages in the software development

One of the main advantages is the ability to improve maintenance reliability, reduce time, cost and human error.

As the world keeps evolving day by day, technology has become an essential thing in our daily lives. Many tech-companies have been established due to huge expectation from people who are always enthusiastic about new inventions. However, not so many companies could survive in very competitive markets like PC computing, software, hardware, etc. In the early 1990s, as PC computing began to proliferate in the industry, software development faced a crisis. Expected estimated the time for a startup business to have a shippable application in production was about three years. This was even worse when it came to others area in the industry. For example, in aerospace and defense, the average time for a typical complex project could easily be more than 20 years. As a result, many projects ended up being cancelled in the middle of the development phase. Some were complete but did not meet all the business’s current needs. Conclusively, project management is the primary cause for those failures. Fortunately, the agile process management has been established from a small group of software leaders to solve the management issue. Agile is a set of development methods which promotes adaptive planning, early delivery. Not only that, it also encourages rapid and flexible responses to requirements changes at any phase of the development process. It is true to say that agile process has given companies, businesses a more sophisticated

Abstract—With the harder and higher level of requirements and faster and better quality pressure from clients, software development is a continue trade off process. How do developers trade off so much elements in software developing process? This research paper will present some research case in the trade off of extreme developing. And this paper will also give details of research approach, research hypothesis, and research conclusion in these case study process. By compare and contrast with some development elements and final software quality of real life research cases, finally a most benefit way to made trade-off in future software development comes out.

With Agile software support, you can ensure disciplined and well-managed project process and encourage teamwork and
