Defect Correction Is The Remediation Of A Software Condition

“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.

It has been observed that in software development, change is unavoidable and must be accommodated for in the life cycle. A number of alternative process models have been introduced in order to attempt to fix the issues in the Waterfall model. An early modification to the standard Waterfall method introduced prototyping as a feedback and discovery mechanism to identify misunderstandings and omissions early on in the process (Neill, 2004). Other process models attempted to further get rid of the risks of misunderstandings by breaking down projects

Agile methodologies promote a structured project management process that encourages self-organisations, accountability and teamwork. These are the best practices that allow customer needs and company goals to be developed through rapid delivery of high quality software and a clear business approach. The software development is based on iterative development that consists of various procedures (cPrime, 2016).

For what types of projects (size, development process) is it a) best b) not well suited (explain)?

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.

The two reports attempt to explore the advantages and disadvantages of utilizing agile software development over the waterfall model. As described in the reports, more and more organizations are considering the agile process approach versus the more traditional waterfall approach. The agile processes evolved in the late nineties and began to emerge as a primary software development method. While organizations are moving towards agile processes, it is unclear which process is the most used. Article A details a survey in which 153 developers were asked to describe their software development processes. The waterfall method was the most used software development method. However, Article B details that 36 out of 66 projects analyzed revolved around the agile methodology. Nonetheless, both articles conclude that one method or approach is not a best fit for all projects.

Abstract: Agile software development is a conceptual framework for software engineering that promotes development in iterations throughout the life-cycle of the project .Software developed during one unit of time is referred to as an iteration, which may last from one to four week Scrum is part of the Agile movement. It is a lightweight process framework for agile development. The Scrum method is most often used to manage complex software and product development, using iterative and incremental practices. And results have been shown about significantly increase in productivity and reduces time to benefits relative to classic “waterfall” processes. But scrum method also have some problems and to overcome the problems a new approach is proposed

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

The paper is a case study analysis of 16 US software development organizations that adopt agile methodologies. The authors aims to provide a more comprehensive understanding of this approach based on the detailed analysis of its practices and how it impact different risk area in the realm of Requirement Engineering (RE). The use of traditional Requirement Engineering recommendations and guidelines in agile development is most of the time problematic and infeasible. These challenges have resulted in the use of different agile practices. The empirical study has identified six agile practices: (1) face-to-face communication over written formal specifications. (2) The iterative nature of requirement engineering process. Only

To overcome these disadvantages of waterfall model, Agile methodology is designed. This methodology uses incremental approach unlike waterfall model which uses sequential steps to develop software. Incremental approach means processing and testing

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].

The Waterfall Methodology no longer works well in the complex development cycles for more robust applications that need to be phased development with regression testing along the way to make sure code updates did not break earlier code already tested and signed off as golden. (Holler et al., 2014, para. 5).

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.

Agile testing is a software testing practice that follows the principles of the agile manifesto, emphasizing testing from the perspective of customers who will utilize the system. Agile testing does not emphasize rigidly defined testing procedures, but rather focuses on testing iteratively against newly developed code until quality is achieved from an end customer's perspective. In other words, the emphasis is shifted from "testers as quality police" to something more like "entire project team working toward demonstrable quality."
