New Programming Improvement And The New Society Of The Product Improvement Organizations

This is the phase where all kinds of testing are performed. We have testers that test the code, functionality, validation of fields, data validation, frontend-backend connectivity etc. when we start this phase. A gives a brief demo to the customer. The product is not fully tested but he still does the demo.

“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.

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.

customer. The first paper focus Agile itself and uses Extreme Programming as an example to show how

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.

Waterfall/Traditional Approach: The traditional approach is a linear approach to software development where project goals, scope and timeline are decided and finalized prior to commencement in project activities. A waterfall project consists of various stages and each stage begins only when the predecessor stage is commenced. The project plan is predefined and provides the framework for the project execution. There are several advantages of adopting a waterfall method. The waterfall method is simple and linear; therefore there is no overlap between different phases. The requirements and plan are rigid and there is an agreement among all parties on project deliverables which serves as the basis for planning, designing and monitoring. Having clear and predefined requirements and design ensures better quality and error tracking efficient as identifying specific errors at design phase is simpler that testing phase. Also, project team members can have prior knowledge of their requirements and thus prepare in advance for the active project. Along with the abovementioned advantages the waterfall method has a few drawbacks. The design and requirements are often based on assumptions and sometimes what seems feasible on paper runs into roadblocks during actual implementation. The requirements and specifications are frozen

However, there are lots of weaknesses for Waterfall during development. The Waterfall model is not flexible and it’s too slow and costly because of the process cannot be changed and need to ensure each step finish before move to next one.

Utilizing programmers on an as needed or project basis allows the company greater flexibility of their programming resources, once again allowing them to conserve precious talent for only the most critical issues.

A minor bug in the Waterfall process will need to be re-written all over again from scratch. SCRUM is more flexible. When an error arises, changes can be made without having to repeat the whole entire process that incurs time and money .This is because the process or steps are done in several different sprints that are not immensely dependent on each other unlike the process that happens within the Waterfall methodology.

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

Most of the agile methods try to reduce risk by developing software in short time boxes, known as iterations, which usually last for one to four weeks. Each iteration is like a mini software project of its specific, and contains all the tasks required to release the mini-increment of new functionality: planning, requirements analysis, design, coding, testing, and documentation. Whereas iteration won’t be adding required functionality to permit releasing the product, an agile software project anticipates to be able to release new software by the end of each iteration. At the end of each iteration, the team reassesses project

This Agile – Waterfall methodology comes with changes to both sides of the methodologies, as the waterfall style development has to forfeit the certainty of expectations for the freedom that agile provides and flexibility. While Agile has to sacrifice the amount of

They also held an implementation workshop in OOPSLA ’95 in Austin, Texas [25]. It is an agile software development framework that is widely used to achieve the agility, iterative, and incremental development in software field. It is used for managing software projects in a changing environment [21]. Scrum is not a process or a technique for building products; rather, it is a framework within which we can employ various processes and techniques [13]. Scrum has the advantage of being very visible and its focus on functional software shows results to management that they can see and get excited about [24]. It increases revenues generated through the provided software. A well-functioning Scrum will deliver the highest business value features first and will avoid building features that will never be used by the customer [6]. Scrum has been adopted by large companies such as Yahoo!, Microsoft, Intel, and Nokia

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

As said if I were the Director of Application Development I would implement the Agile
