Agile Versus Waterfall Software Development

PRINCE2® (Projects in Controlled Environments), is a widely used project management methodology that navigates you through all the essentials for running a successful project. It provides project managers with a practical roadmap from conception to close.

Scope planning in APM is a high-level activity because little is known of the solution. Change is a key part of APM, making the scope very flexible. The scope is constantly redefined due to the series of iterations. Ideas could be added at stage of the project. Documentations is present but not as detailed as in TPM. APM focuses on developing the most important part of the scope first and then proceed to the next.

There has been a lot said in the last few years about Agile project management methodologies, and I have found that the general feeling is that Agile although not perfect tends to provide better results in software development projects than waterfall and other methodologies. People tend to be very opinionated about it, and in my experience there three dominant positions about Agile: you either love it, hate it or you don’t care, in other words, you do not believe in methodologies at all, you think they are all a waste of time and effort.

Development Teams at Company X for the past 6 months have provided inconsistent estimations, derailing project timelines and costing 175% of predicted expenses. To help regain control of project timelines and estimation practices, AA Consulting’s team of Agile specialists have been working with the Company X delivery teams.

Agile methods, unlike ISDs, bring constant iterations, constant user involvement, and frequent releases and close communication. Clutterbuck emphasizes how a case study of one small SME shows the success gained when it moved away from ISD towards agile management. Overall, agile management anticipates risks, reacts aggressively to new challenges or encrustations, and allows all parties and decision makers to draw closer together. The only challenge, Clutterbuck (2009) argues, is that agile management does come into conflict with the need to formalize contractual obligations between the customer and the developer or producer of the product (Clutterbuck, 2009).

Scrum (link to the page http://en.wikipedia.org/wiki/Scrum_(software_development)) is a project management methodology. It is mostly used in I.T. and Software Development. Scrum is an iterative and incremental variant of Agile (link to http://en.wikipedia.org/wiki/Agile_software_development) Software Development Methodology that was created by Ken Schwaber (Link to http://en.wikipedia.org/wiki/Ken_Schwaber) and Jeff Sutherland (http://en.wikipedia.org/wiki/Jeff_Sutherland) in the 90's. S

The waterfall model was legally introduced as an idea through a paper that had been published by a man called Winston Royce in the year 1970. However, due to the waterfall model being introduced by Winston Royce himself, it had been introduced as an example of a flawed software development method, which was vulnerable due to its shortcomings. The waterfall model philosophy had been inherited from the hardware manufacture and construction strategies that had been in practice in the year 1970s; therefore it had a structured approach to the software development itself. In comparison to the agile methodology, which developed in the year 1990s where the developers had decided to break away from the traditional structured, segmented and administrative approaches, which were being made to the developed software, and progressed towards more of the flexible development styles. The term Agile can be referred to as being lightweight methods, which had been declared in a research paper in the year 1974 by Edmonds. Furthermore, some of the most noticeable and common agile methods of the software development that subsequently had been evolved were known as Scum in the year 1995, 'Extreme Programming ' in 1996, 'Adaptive Software Development ', 'Dynamic Systems Development Method ' in 1995 and 'Feature Driven Development '. In the year 2001, a team of developers in the agile software development had declared the agile manifesto. The agile

Imagine an enterprise software development project where the customer says "we are going to take a long time to get this done and we don 't expect to see any results for at least two years". Can you imagine it? Me neither, and the truth is that it will probably never happen:) So what is reality? In the real world of enterprise software development, the key for any development team is to provide maximum value to and work closely with the customer, to be able to build a culture of true ingenuity, and to be able to meet the customer 's changing needs in a way that there is minimal disruption, if any.

Time Box: A time box is a previously agreed period of time during which a person or a team works steadily towards completion of some goal. Rather than allow work to continue until the goal is reached, and evaluating the time taken, the time box approach consists of stopping work when the time limit is reached and evaluating what was accomplished.

The contrast of the Object Orientated Software Engineering approach to an agile approach for Software Engineering.

In the late 1990’s, there are several methodologies which attract public attention.These methodologies underlined importance of collaboration between the development team and business stakeholders; frequent delivery of business value, tight, self-organizing teams; and smart ways to craft, confirm, and deliver code. The term "Agile" was applied to this collection of methodologies in early 2001 when 17 software development practitioners gathered in Snowbird, Utah to discuss their shared ideas and various approaches to software development. This joint collection of values and principles was expressed in the manifesto of agile and the corresponding twelve principle.Software testing is the key for software quality. Agile software development method that is new methodology in recent years embraces change and fixes attention on the delivery of high quality software. Extreme Programming, the

There are many different software development methodologies for a software project to choose from, each of them has their own pros and cons, which one is the right one for your organization. In this article, we will discuss the different types of project environments that are available, first we will start with the Agile methodology pros and cons and then we will talk about the suitability of the method with different project environments.

Abstract – Today, there are millions web application or web app on the internet, including app market, such as Amazon app store, Apple Store, Chrome App Store, etc. The web application is server-based application, and client no need to install the software in their local pc or laptop. User just need to use compatible browser to access the web application at anywhere and anytime. In fact, the web application still a form of software. To develop a successful software, an appropriate software development method is critical. Because, it is a guide book to monitor the development life cycle throughout the development project. In this work, two popular methods will

viewed as the set of practices and techniques which have particular standards and values. These share the combined properties of both iterative and incremental development process which tackles requirement changes quickly to satisfy the customer for good quality products. Agile methods have four values: individuals and interactions over processes and tools, working software over comprehensive documentation,

The initial software development methodologies were more than methodologies, free for everyone, as organizations endeavored to profit from the latest computer related technologies. As the industry gained more insight about designing the software, fixed techniques for administering and predicting the market price of the software development projects came into practice.
