To this point, one stark contrast between the Waterfall and Agile methods of software development is the degree to which they involve the customer. In this sense it is easier to think of the Waterfall model as being more “predictive” and the Agile model as being more “adaptive”. There are milestones in either case, but the changes that are a result of customer input drive the flow of development in an Agile system (Arken 2008). One can see how the “adaptive vs. predictive” differences can become more of a problem where finances are concerned.
For this paper, I will be comparing the Waterfall and Agile methods of software development. The primary articles used for citations will be from “Agile for millennials: a comparative study” and “The Waterfall That Won’t Go Away” with supplementing citations from “Hybrid Software and System Development in Practice: Waterfall, Scrum, and Beyond.”
AGILE is a methodology that promotes continuous iteration of development and testing throughout the software development life cycle of the project. Both development and testing activities are concurrent unlike the Waterfall model
There are several software development methodologies are available and each of them has its own strengths and weaknesses. Not all methodologies could be appropriate for all projects. Each method is best known for certain
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
Once the design is complete and the coding begins, A’s team enters the implementation phase. A is good at C and C++. He is not a fan of Java. He insists that the product be designed using C or for object-oriented nature using C++. Due to this reason, most of his Team members possess limited skills. In this day and age with so much advancement in technology, I am not sure why A is stuck to the basic languages without adopting change. Once the coding is complete, they move on to next phase. During that phase A gives an update to customer via email on the progress of the project and its timeline.
In order to achieve successful results within established time-frames and budgets, project managers are likely to employ methodologies models. A project methodology is a model that aids managers to plan, design and implement their project goals. Project methodologies are helpful to project manager in any field, for instance, Niel Nickolaisen CIO at the Western Governors University, is an advocate for the agile software development methodology. As these models grants flexibility when dealing with stipulations and scope changes on a project. Needless to say the agile software development methodology is just one example of a varied assortment of methodologies, each with their strengths and weakness. As such, it is up to the project manager to decide which methodology fits their needs, as there isn`t a one fits all solution.
“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.
The agile methodology results in actual workable software, brought to you in an incremental technique. That is certainly different to traditional, waterfall project procedures, where the client / user has generally to wait patiently till the very end to be able to test and obtain benefit from the software program.
Agile Development is one of the methodologies use in software engineering to help develops software. Today, there are a lot of different approach to Agile method. However, they all share the same value and principals. This method is value interactions over team and customer, workable software, and adaptable to change. Over the processes, documentation, contract, and plan. Agile developer also following 12 principle. 1, Their first priority is to delivery fast and quality software that will satisfy customer. 2, be adaptable to any change in requirement at any point in time, Agile development always
This paper will take a in depth look at what makes AGILE “AGILE”, including the history, uses, and arguments for and against its use.
Agile techniques should be used to solve the current issues faced by the company as agile techniques normally being used by the software industry help the business to act in response under the unpredictable situations faced. In Agile methodologies opportunities are been provided to evaluate whether the project is under the direction all through its development cycle. All this is being accomplished with the help of regular tempo kept in work, and the teams must show a product which is having the desired potential.
These iterations typically last one to four weeks and can almost be seen as small projects with actual deliverables (Sindhgatta, Narendra & Sengupta, 2010). Sindhgatta, Narendra and Sengupta (2010) embarked on a case study based on the Scrum agile methodology. Two key roles are the ScrumMaster and product owner. The ScrumMaster is responsible for helping the development team use the Scrum framework and the product owner is the liaison between the development team and the business or end users (Sindhgatta, Narendra & Sengupta, 2010). At the end of each sprint, code is delivered and tested, and feedback is looped back into the model. This is in stark contrast to the waterfall method and facilitates the likelihood of constant change in the agile model (Sindhgatta, Narendra & Sengupta, 2010). As a project evolves, members of the development team and the business may get a better understanding of the requirements which can lead to changes in code that may have already been created as part of earlier sprints (Sindhgatta, Narendra & Sengupta, 2010). This concept of project evolution with changing requirements needs to be allocated into the project schedule as extra time for recoding and retesting (Sindhgatta, Narendra & Sengupta, 2010). This extra time is not something that is built into a waterfall model because the requirements should be a static entity and rework should not be an option
Different methodologies are used nowadays by a project manager to achieve their project goals. Although all the methodologies have common process for management but their execution differs. In this paper my intention is to discuss the most commonly used project management method called Agile. This methodology is commonly used in software projects because of its iterative development way and its flexibility for a requirement changing environment like in the case of a software project where the requirement keeps on changing as the project progress.
This paper describes Agile development methodologies and their benefits. Section II presents key elements of Agile. Section III presents benefits of Agile development methodologies over traditional waterfall methodologies.
