Analysis Of 16 Us Software Development Organizations

Requirement engineering is an integrated part of a software engineering and it is defined as a process concerned with goals, functions and constraints on software systems. Requirement engineering also concerned with identifying the stakeholders and their requirements as to how the software system should be, how it should behave and how it should evolve among similar software’s over the period.

Cost and resource needs are higher for traditional than Agile due to Waterfall’s sequential development phase of all requirements determined in the beginning, software design and finally implementation of master design. The need for all information up front takes substantial time to gather and the sequential design does not allow for project changes as the flow enters into the programming stage. With Agile, costs remain low because there exists an incremental and iterative approach to the project, meaning less time is used to collect all requirements up front, the

Agile processes do not devote much time up front to formal system specifications, but rather relies on continuous communication with the customer throughout the development process. The process accounts for the fact that needs often change or cannot be fully developed early on and is flexible to this. (+)

Introduction to Agile Methods by Hayes and Andrews gives detailed-oriented information about different aspects of agile methods like why there is a need for new software development processes and pitfalls of traditionally methodologies and how this lead to emergence of agile methods. They describe various existing agile methods but describes only one in great detailed – Extreme Programming(XP). They define Extreme Programming as agile, adaptive software methodology having well defined values - Communication, Simplicity, Feedback, and Courage. Failing in achieving this values will result in failing Extreme Programming. Extreme Programming is used only when you have complete understanding of the business and requirements. Extreme Programming follow a series of iteration to deliver the final project. Initially the story heard from the customer is broken down into smaller stories such that the developers can assign time to develop that stories and then its deliver to the customers for feedback. Coach plays a vital role in Extreme Programming. Afterwards Hayes and Andrews describe how XP differs from traditional methodologies. They also explain the common misconception about Extreme Programming is spread around the world. There are only fewer companies in the world that uses Extreme Programming because people are afraid of changing to new methods.

“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.

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”).

There is a cross section of projects ranging from a few weeks to a few years. There are also a wide cross section of customers, those capable of articulating clearly their requirements and the ones that are not clear on their requirements and the overall outcome to be achieved. The level of programmers within the Information Technology Department, where development work is executed, range from intermediate to advance or above average programming competence. The Waterfall approach is easier to manage and can be utilized for projects where there are clear requirements and the project is determined to be a long term one. Also, this method may be best suited given the organization’s requirements for thorough documentation and project accountability, when it comes to budget and cost. The Agile methodology can be used for projects where the requirements as well as the expectation from the end product are not as clear. The developers that are above average in terms of their competence can also use this method. In addition, the Agile method is also best suited for the projects that would require rapid

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.

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.

Requirements and issue management systems allow managers or leaders to classify and affiliate characteristics with them, and to establish and evaluate dependencies and other common ties. Requirements set the stage for a project and issue management is an important process of identifying and resolving issues (Cook, 2015). Shaw Industries used an agile methodology called Scrum to improve relationships between IT and business partners to ensure project success (O’Brien & Marakas, 2011). IT used this tool to work collectively as a group and determine which project will give Shaw Industries the best value. They divided the project into segments: 30 days to complete a series of tasks. Once the

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.

In this paper, Rapid Application Development (RAD) and the Agile Development Method (ADM) are compared and contrasted. The paper begins with a summary of each of the articles referenced on the title page, including the pros (benefits) and cons (risks) of each method. The paper then addresses how the two methods might be applied to my company, Parametric Technology Corporation (PTC), an enterprise software solutions provider headquartered in Needham, MA, with about 6,000 employees in over 70 offices worldwide. Finally, the paper concludes with my views on which of the two methods would be more valuable in a development setting. The authors of the article, “Risks of Rapid Application Development,” open by cautioning that software development includes – or should include – more than the speed at which an application is delivered, identifying maintainability and reusability as equally important characteristics. The purpose of the article is to fill a gap in the literature (at the time of the writing of the article) about the long-term implications of RAD tools on both the software itself and the organizations and developers who use it. The authors emphasize that the choice to use RAD is not just a capability decision, it is also a human resources management decision. In addition to a much faster development lifecycle, RAD tools also include requirements planning, design and modeling, code writing, and testing, with the requirements and design phases accounting for about 30% of

In conclusion, agile software development is a very exciting and useful approach, although some project suit agile more than others. The collaboration and visibility can provide a much better and rewarding experience for the team to develop software products. Over the last years, many companies dramatically improved their performances
