A Study On Agile Software Development Business Essay

A Study On Agile Software Development Business Essay Agile software development is a group of methodologies whose basis is iterative development. The requirements and solutions in this develop through collaboration between self-organizing cross-functional teams. Agile methods usually endorse a well-organized project management process that promotes many inspection and adaptation. It endorses a leadership philosophy that encourages teamwork, self-organization and accountability, a set of engineering best practices intended to allow for rapid delivery of high-quality software, and a business approach that aligns development with customer needs and company goals. Agile methods promote an iterative mechanism for producing software. They further enhance the iterative nature of the software lifecycle by tightening design-code-test loop to at least once a day (if not much more frequently) as opposed to once per iteration. The theoretical foundations of this framework are found in modern approaches to operations management and analysis, such as lean manufacturing, soft systems methodology, speech act theory (network of conversations approach), and Six Sigma. Agile Vs Waterfall Waterfall Model: The Adoption of waterfall has helped to drive down the failure rate of software development projects, but even with rigorous project management and processes, a full 70 percent of software projects using this methodology fail to meet their objectives. To put this in perspective, waterfall software projects have less than half the success rate (66 percent) of going over Niagara Falls in a barrel. Figure: The waterfall process for software development Agile approach differs from Waterfall in more than one ways, however the major point of difference is that in the waterfall process there are several checks carried out in phases and the team is expected to deliver a particular part in each phase, however in agile the team is expected to carry out their project in iterations instead of phases. At the end of each iteration, the deliver able expected is a working code that can be continuously improved in order to cope up with the ever changing needs of the demanding client. However, in case of Waterfall, it is assumed that all the needs and requirements of the client are known precisely right at the beginning of the project. Alibi the software development industry is such that , it is often very difficult to understand the exact requirements of the customer at the beginning of the project. This is the major shortcoming of waterfall, where the development team is seldom able to meet the expectations of the customer. Agile methodologies embrace iterations. Small teams work together with stakeholders to define quick prototypes, proof of concepts, or other visual means to describe the problem to be solved. The team defines the requirements for the iteration, develops the code, and defines and runs integrated test scripts, and the users verify the results. Verification occurs much earlier in the development process than it would with waterfall, allowing stakeholders to fine-tune requirements while they’re still relatively easy to change. 1. XP Extreme programming mainly focuses on the development; it does not lay too much emphasis on the management perspective of the software projects. The main purpose with which XP was designed was that all organizations could adopt it for free in its entirety or partly.
