Dual Application Model For Agile Software Engineering

“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.

One of the initial steps in researching a problem is to know exactly what the problem is and compose a problem statement that unambiguously identifies and defines the problem to research. Sekaran (2003) said, “No amount of good research can find solutions to the situation, if the critical issue or the problem to be studied is not clearly pinpointed” (p. 69). The area of research for this paper focuses on software development, in particular, the study of agile software development methodologies and if these methodologies are successful in delivering software on time, within budget, and includes the requested features.

As technology is increasing on a rapid scale there is much need for the different software development approaches to be modified and enhanced in order to face the present customer requirements and blooming Technology market. Believers of the old approach of software development finds its best in developing with planning, reusability, predictability that helps to develop a perfect software product. On the other hand trending designers likes another model of software development that is Agile Methods, both the plan-driven approach and the agile methodology has their own pros and cons. If combined and developed a good end product can

In Early 2000s, various software systems development methodologies were introduced and were started getting popular. One of them was agile method. Agile is a group of the latest and popular software systems development life cycle methodologies work in iterative way. All the requirements/needs and solutions are solved through collaboration between a development team and a business stakeholder. Agile method usually enhances an organized project management method which promotes regular assessment and revision. And the scrum is a sub group of agile. It is an iterative and incremental agile software development methodology for managing complex software and product development (“The Scrum Guide”).

The idea behind Agile is to put people before processes, to deliver working software versus mountains of documentation, to collaborate with clients rather than negotiate contracts, and lastly to be agile rather than rigidly following a plan (History: The Agile Manifesto).

Agile Software Development: The iterative development strategy focuses on incremental delivery of usable software ("What is Agile Software Development?", 2017)

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.

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].

Software development is a field where developers thrive to provide products faster, better and very inexpensive methods. “Agile Development” term used for several iterative and incremental software development methodologies. Each agile method is unique in its approach, they all impart a typical vision and core attributes. As matter of fact all the methods are fundamentally incorporate with each other and having a review system provides successive ways to enhance, refine and deliver a software system. The below figure represents the steps followed in agile development

Studies have identified several problems that could result from the lack of Agile re-engineering and suggest different approaches to address these problems. These methods include using win-win negotiation, AHP, NFR, tractability matrix etc. These approaches might help to mitigate the challenges and help in obtaining the complete benefit of using an Agile method.

There are a few popular methodologies in software development. Agile and Scrum technologies are among the most mentioned and used ones. Agile is like a big father for a number of other methods including Scrum. The framework of Agile contains basic principles being a part of characteristics for different methods derived from Agile. Nonetheless, Scrum is quite independent and can be referred as a separate style of software producing management. That’s why the topic of this publication is agile vs scrum.

The object orientated software engineering approach or the waterfall approach is an example of an object-modelling language. In this essay I will detail the advantages & disadvantages of using this methodology. I will also compare and contrast this methodology with an alternative approach of software engineering which is the agile or scrum approach.

Agile development is a term used in software development to describe incremental software development methodologies. It is a type of incremental model because, in incremental model the whole requirement is separated into many separated builds. Here, the software is developed in incremental, rapid cycles resulting in small incremental releases with each release building on its former functionality. Each release is critically tested to make sure that the software quality is maintained.

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.

First of all, here is some brief description about Agile development model and Waterfall development model. Agile development model is a type of Incremental model which means the software is developed in incremental and rapid cycles. This results in small incremental releases with each release building on previous functionality. Software quality is ensured to maintain well by testing each release thoroughly. It is usually used for time critical applications.
