Agile development methodology
Agile development is a system development strategy where the system developers are given the competence to choice from a wide selection of appropriate tools and techniques that can be used when accomplishing a certain task on hand. Agile methods are the integration of different kinds of approaches of system analysis .Design application is considered suitable to the problem that is being solved and the system being developed. It also focuses on different aspects of the software development cycle. Agile methods are also known as agile methodologies.
According to (1):
“agile methods or agile methodologies are a software developing method that is people focused communications- oriented, that is flexible ( ready to adapt to expected changes at any time), speedy , lean (shorting timeframe and costs on Improved quality), responsive and learning ( focused on improvement during and after product development)”.
You get many different types Agile Methodologies such as scum, XP, DSDM which are popular agile methodologies.
Scum is the most popular way to introduce agility because of its simplicity and flexibility. It’s the most popular adopted agile method .It is an agile development method which is mainly concerned particularly on how to manage tasks in a team based development environment. According to (2) :
Scum was developed by Jeff Sutherland & Ken Schwaber. This method involved one or more small teams that work ...

Agile project management is an iterative approach to the planning and monitoring of project processes. Agile projects are conducted in smaller tranches called iterations with each of these iterations closely reviewed and critiqued by the project team (employees, representatives of the clients etc.). The knowledge gained from this process is then used to ascertain the next steps of the
Agile Methods (Schwalbe, 2014): This method involves the iterative flow of work and delivery of software in less iterations. Agile methods are used more for faster delivery of the project to the customer which considers the business benefits, quality of the product and
I recommend Scrum as our methodology because we do not know the requirements, the system needs to be developed quickly, and the system needs to be reliable. Scrum excels at new and changing requirements as well as adapting to new client needs. May Enterprises is currently unsure of what exactly they want so an adaptable methodology would excel. Scrum aims at creating a working system at the end of each sprint. Creating an implementable system quickly and incrementally is one of the main goals of Scrum. Also, because

When comparing and contrasting waterfall and agile, they both use the same type of building blocks for the project: scope, cost, schedule and performance. They both also analyze, design, build, test, and deploy the requirement needed for the end result. The difference in these terms for each method is that when using waterfall for scope, cost, schedule, and performance, it sets the scope up front and then allows the cost, schedule, and performance to change depending on what is needed. An agile method will set the cost, schedule, and performance upfront and then have the scope vary, depending on what the company’s requests are after a working prototype. The waterfall is an iterative method meaning the next step cannot begin until the current one is completed. Once the current step is completed, it cannot be revised in anyway unless the project is scrapped and begin again. If the waterfall method is chosen, then the project team
Software methodology development processes developed to streamline associated software development process, with the Waterfall methodology being the first such process in 1970. After the said such time, many new development methodologies such as Agile and Spiral methodologies developed to facilitate the shortcomings of Waterfall. As the Spiral methodology is an iterative development module, where methodology continuously cycles through phases. The Agile Method is an incremental development methodology focused on providing flexibility, through an incremental development. The software development methodologies each serving unique purposes for risk analysis based projects, large-scale, small scale, well-define, and customer-driven projects. Consequentially,

Rather than the long drawn out release cycles in the previously popular waterfall methodology, the agile methodology suggests regular short sprint release cycles called iteration. This allows the customers and stakeholders to have more involvement within the software development process. The iterative approach has become vastly effective in helping software developers improve their skills in estimating schedule for remaining tasks. Schedule estimation is one of the most difficult responsibilities for developers because software issues are common and are unpredictable by nature. By breaking the large requirements down into more manageable sub requirements, the agile process naturally promotes better estimation [1]. Agile methods are people-oriented rather than process-oriented, Qumer and Hender-son-Sellers [2] offer the following definition for the agility method: ‘‘A software development method is said to be an agile software development method when a method is people focused, communications-oriented, flexible (ready to adapt to expected or unexpected change at any time), speedy (encourages rapid and iterative development of the product in small releases), lean (focuses on shortening time frame and cost and on improved quality), responsive (reacts appropriately to expected and unexpected changes), and learning (focuses on improvement during and after product
When expressing the holistic approach of agile information systems applied to business, it becomes imperative that one addresses the specific framework toward the approach. Although, holistic in theory the specific framework for strategy itself must break down into independent strategies and examined as an ongoing whole. Take the company Amazon.com for example, their information system strategy combines the independent strategies of the framework however, they independently transpire and flow from one to another through a process of ever-changing information collaboration. In the year 2000, Amazon.com chose to provide this service to customers, which included a network of retailers through an efficient information system platform structured for e-commerce. Currently, the world’s largest retailers are involved in their ever-evolving achievement of services embracing technology, retailing, and customer service through order satisfaction. The company’s services encompass a spectrum from world merchandise leaders to small-scale merchants leveraging and incorporating an incremental sales channel for new products. In addition, they provide a platform, which allows independent software developers to build profitable applications, and services, which create an ongoing input of tradeoff analysis, and optimization, which ultimately enables the company to provide its merchants and customers an ever-expanding variety of services. Amazon.com in the aspect of agile information systems through their own innovation allows an ideal example in the explanation of strategic information systems analysis.
Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.
TRIARQ Healthcare Agile development is not a methodology in itself. It is an umbrella term that describes several agile methodologies. At the signing of Agile Manifesto in 2001, these methodologies included Scrum, XP, Crystal, FDD, and DSDM. Since then, lean practices have also emerged as a valuable agile methodology and so are included under the agile development umbrella.
A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.
Scrum is basically a framework for agile development. Scrum is a process that is used most of the time during complex projects in software development. It is also a simple yet affective way to manage work. The strategy in Scrum is to divide members into a team and have them work together to achieve a common goal or project. Scrum provokes communication between the members of the teams. This communication is imperative to the success of the project.
