Rapid Application Development And The Agile Development Method

Cost and resource needs are higher for traditional than Agile due to Waterfall’s sequential development phase of all requirements determined in the beginning, software design and finally implementation of master design. The need for all information up front takes substantial time to gather and the sequential design does not allow for project changes as the flow enters into the programming stage. With Agile, costs remain low because there exists an incremental and iterative approach to the project, meaning less time is used to collect all requirements up front, the

“Agile” was first introduced in 2001, by a team of software engineers looking to improve their adaptiveness and responsiveness to ever-changing requirements. Not knowing where to begin, the team began by formulating principles, which they would use to guide their new development process. Which, in turn, lead to the creation of the Agile Manifesto, and thus a new methodology was born.

One of the initial steps in researching a problem is to know exactly what the problem is and compose a problem statement that unambiguously identifies and defines the problem to research. Sekaran (2003) said, “No amount of good research can find solutions to the situation, if the critical issue or the problem to be studied is not clearly pinpointed” (p. 69). The area of research for this paper focuses on software development, in particular, the study of agile software development methodologies and if these methodologies are successful in delivering software on time, within budget, and includes the requested features.

There are many different methodologies when it comes down to software development. Some methods may be too complicated for a small business to use. Agile development is a methodology that works extremely well for small businesses, and focuses on the strength of people-centric viewpoint and collaboration. Some benefits of agile development are increased productivity, expanded test coverage, improved quality/fewer defects, and higher customer satisfaction. Some challenges in

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].

Agile methodology is a software development lifecycle which designed to produce faster development and high quality results compared with the traditional lifecycle. The Agile method focuses on incremental and iterative development where requirements, specifications, design, implementation, and testing continue throughout the project lifecycle (Nanthaamornphong, Morris, Rouson & Michelsen, 2013). Agile software development methods enable software developer to be more flexible and responsive to the changing environments and customer demands. However, Agile adoption comes with special challenges and fundamental organizational changes are necessary for successful outcome.

In this paper we have explored and analyzed data from various Research papers, Magazines, online Journals and news articles to find out the various challenges faced by organizations while adopting Agile software development methodology. The challenges include User story overload, Prioritization stress, Code refactoring, Sprint Duration, Documentation, Lack of expertise, Process related issues, and Management and organizational context. Additionally we have mentioned solutions to some of the challenges that may help in an effective adoption of

Agile development is a term used in software development to describe incremental software development methodologies. It is a type of incremental model because, in incremental model the whole requirement is separated into many separated builds. Here, the software is developed in incremental, rapid cycles resulting in small incremental releases with each release building on its former functionality. Each release is critically tested to make sure that the software quality is maintained.

A problem face nowadays by many companies is related on decide between continue to use a plan driven methodology, such as Waterfall, or trying a different approach like Agile. The major problem might be the way these two concepts are often presented as being mutually exclusive. This dichotomy often causes an automatic rejection of one methodology over the other, making it even more complicated to decide between one or another. This polarization misconception is what makes so difficult to successfully applying an Agile project management approach. Instead of trying to use the best of each approach, or to adapt for its needs, companies sometimes try to force their business and projects to one of those extremes. The problem with

This essay involves the comparison and contrast of the different methodologies used by programming teams. Among these methodologies are; System development life cycle (SDLC), Extreme programming and Agile methodology. Software development methodologies are the frameworks involved to structure, plan and control the processes used in developing an information system. The system development life cycle (SDLC) is a conceptual model which is involved in most project management and used for large scale projects with relatively large number of developers. A good example of SDCL methodologies includes; waterfall model. The SDCL takes a lot of time to produce complete products but of high quality. Agile methodology is a conceptual framework used also in project management and it is designed for small projects with few developers. Extreme programming on the other hand allow for communication with customers and by doing so it ensures interaction between developers and consumers in order to change as fast as the customers' needs and desires changes. Even though there different methodologies, agile methodologies seem to have a lot of advantages over the Extreme programming and system development life cycle. Since it combines a number of other methodologies to come up with a better way for developer to produce faster and change to as customers desires changes.

One is the traditional development approach that begins with capturing the organisations desires and then progresses in order through design, development, testing and finally implementation. Alternatively, numerous IT professionals make use of Rapid Application Development methodology which basically is a faster and realistic approach. This methodology offers potential for numerous advantages including decreasing the risk of misunderstandings of business desires and increasing the possibility of the project been accomplished much

[1]The Agile software development (ASD) methodologies have been established in various streams like academic, educational and also in professional software development. Understanding of how ASD methodologies are used, the kind of acceptance, successes and failures they have in the mentioned streams would be the main exploration. The findings from the web-based survey of Microsoft employees who involved in development, testing and management have indicated that around one-third of the people use ASD and the SCRUM is the most popular ASD methodology. [2]Agile methods can be mainly used in environments which are unpredictable and helps in succeeding over such environments which are in the reality today.

In conclusion, agile software development is a very exciting and useful approach, although some project suit agile more than others. The collaboration and visibility can provide a much better and rewarding experience for the team to develop software products. Over the last years, many companies dramatically improved their performances

The software development life cycle is utilized by the software industry to design, develop, and test software. The objective of the SDLC is to provide high quality software that exceeds customer expectations and meets timeframes and cost expectations. This paper will provide a brief overview of the SDLC and the various stages throughout the life cycle. There are various SDLC models such as the waterfall, agile, and rapid development. The writer will describe traditional waterfall method utilized at his current place of employment and discuss areas for improvement.
