Comparing Articles That Tackle The Waterfall Method And The Agile Management Approach

Many business use the agile organizational methodology. As they require the ability to remain flexible, enduring ever-changing requirements. The agile organization develops more mission-critical, high-profile systems. Sharing responsibility within small teams (of 15 or less) is also a main principle of an agile organization. Never is a hierarchy design operational in the agile organization, as the group possess the ability to over ride decisions made by management. The agile type of organization displayed itself over time as an entrepreneurial type of organization providing the high-speed changing rather than the standardization of a bureaucratic organization (Johnson, Jackson, & Burrows, 2011).

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 processes do not devote much time up front to formal system specifications, but rather relies on continuous communication with the customer throughout the development process. The process accounts for the fact that needs often change or cannot be fully developed early on and is flexible to this. (+)

Introduction to Agile Methods by Hayes and Andrews gives detailed-oriented information about different aspects of agile methods like why there is a need for new software development processes and pitfalls of traditionally methodologies and how this lead to emergence of agile methods. They describe various existing agile methods but describes only one in great detailed – Extreme Programming(XP). They define Extreme Programming as agile, adaptive software methodology having well defined values - Communication, Simplicity, Feedback, and Courage. Failing in achieving this values will result in failing Extreme Programming. Extreme Programming is used only when you have complete understanding of the business and requirements. Extreme Programming follow a series of iteration to deliver the final project. Initially the story heard from the customer is broken down into smaller stories such that the developers can assign time to develop that stories and then its deliver to the customers for feedback. Coach plays a vital role in Extreme Programming. Afterwards Hayes and Andrews describe how XP differs from traditional methodologies. They also explain the common misconception about Extreme Programming is spread around the world. There are only fewer companies in the world that uses Extreme Programming because people are afraid of changing to new methods.

“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.

Thus, Agile came into play. This is a faster and smaller method over traditional. Stakeholders get together with small teams to look at cost, resources and expected time frames. This team figures out the computer verbiage, checks and balances, verification coding, iterations, number limits, scripts, all in the early stages of development.

The agile methodology with scrum-based approach has worked effectively for our organization because it is flexible and iterative with continuous feedback and constant communication and favored by frequent and short delivery schedules (Chang, 2010). This approach brings about a high level of competence and high level of motivation to work. It also instills discipline and respect for time by

In other words, how can PMO and agile live together in an organization? Therefore, the target of this paper is to address the issues and clarify the relationship between the PMO and Agile methodology.

There is a cross section of projects ranging from a few weeks to a few years. There are also a wide cross section of customers, those capable of articulating clearly their requirements and the ones that are not clear on their requirements and the overall outcome to be achieved. The level of programmers within the Information Technology Department, where development work is executed, range from intermediate to advance or above average programming competence. The Waterfall approach is easier to manage and can be utilized for projects where there are clear requirements and the project is determined to be a long term one. Also, this method may be best suited given the organization’s requirements for thorough documentation and project accountability, when it comes to budget and cost. The Agile methodology can be used for projects where the requirements as well as the expectation from the end product are not as clear. The developers that are above average in terms of their competence can also use this method. In addition, the Agile method is also best suited for the projects that would require rapid

From my perspective, though not being privy to a genuine cost analysis, yet being well versed in areas that do impact our financial well-being – most notably where challenges in back-end scenarios could be met more immediately and internally rather than hired out and realized on an external vendor’s own timeline – I will provide an analysis that clearly displays the benefits of agile methodology over our current use of waterfall. With this essay, I intend to provoke change, though I do understand that further consideration and discussion will be required prior to any realization of meaningful change.

Focus is kept on the recurrence of condensed work cycles and also at the functional product yielded by the outcome, but in waterfall technique only once chance is been given to the development team to keep the project aspects right. But under the agile technique each and every feature of development including the design, requirements, is thoroughly checked under its lifecycle (Mahfuj et al, 2012). There is always some time to steer in another direction if a team stops at regular interval say after every two weeks and re-evaluates the project done.

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].

Compared to the agile, another famous software development mode called waterfall is driven by technique documents and this mode require the team to write a lot of requirement documents containing all the requirements to a certain software. It is written to allow people to understand what software should do. So the developers will develop the functions of software according to the documents strictly. But the agile software development just focuses on the necessary document. It is avoid taking a lot of time to write the requirement documents. Its opinion is that the face to face communication between the human is the most important thing. So the agile think the human is

Agile methodology is an approach to project management and agile software methodology is not a one methodology but a set of methodologies which share common characteristics to achieve business goals. Before 1950’s project management have taken place in an informal way for many eras and after an ameliorating of formal project management methodologies began to be defined and swiftly spared through the industry rather than traditional methodologies. The traditional approach of project management identified a set of sequences of steps to be completed such as initiation, planning and design, execution and construction, monitoring and controlling and completion but not all projects will have every stage and some projects can be terminated before they reach completion. When it derived to IT industry in the past few years there’s been

Software development is one of the highest demands in all over the world. We use software development techniques to solve the problems and to satisfy customers. Agile software development is a conceptual framework for software; it is also a group of software development methods based on iterative development. In 2001, agile software development was created by seventeen people with a desire to find alternative approaches to software development. The most important thing about agile methods are team work, conveying information to the team, face to face conversation, and satisfy the customer. There are various methodologies but I am going to describe the most popular ones.
