agile view of process in software engineering

agile is a time-bound, iterative approach to software delivery that builds software incrementally from the start of the project, instead of trying to deliver all at once. because these businesses are operating in an ever-changing environment, it is impossible to gather a complete and exhaustive set of software requirements. without these requirements, it becomes practically hard for any conventional software model to work. as a consequence, a conventional software development model fails to deliver the required product. it was specially designed to curate the needs of the rapidly changing environment by embracing the idea of incremental development and develop the actual final product. a software company named abc wants to make a new web browser for the latest release of its operating system. the company’s head assigned two teams named team a and team b for this task.

the team a decided to play by the book and decided to choose the waterfall model for the development. team b after a heavy discussion decided to take a leap of faith and choose agile as their development model. but then out of blue due to the rapidly changing environment, the company’s head come up with an entirely new set of features and want to be implemented as quickly as possible and wanted to push out a working model in 2 days. and moreover, it was practically impossible for them to implement new features since waterfall model there is not reverting back to the old phase once you proceed to the next stage, that means they would have to start from the square one again. team b was ahead of team a in a lot of aspects, all thanks to agile development. and it was a piece of cake for them to add the new requirements. agile is a framework which defines how the software development needs to be carried on. agile methods and practices do not promise to solve every problem present in the software industry (no software model ever can).

agile sdlc model is a combination of iterative and incremental process models with focus on process adaptability and customer satisfaction by rapid delivery of working software product. these builds are provided in iterations. in agile, the tasks are divided to time boxes (small time frames) to deliver specific features for a release. each build is incremental in terms of features; the final build holds all the features required by the customer. the agile thought process had started early in the software development and started becoming popular with time due to its flexibility and adaptability. working software − demo working software is considered the best means of communication with the customers to understand their requirements, instead of just depending on documentation.

customer collaboration − as the requirements cannot be gathered completely in the beginning of the project due to various factors, continuous customer interaction is very important to get proper product requirements. predictive methods entirely depend on the requirement analysis and planning done in the beginning of cycle. agile uses an adaptive approach where there is no detailed planning and there is clarity on future tasks only in respect of what features need to be developed. there is feature driven development and the team adapts to the changing product requirements dynamically. customer interaction is the backbone of this agile methodology, and open communication with minimum documentation are the typical features of agile development environment. agile methods are being widely accepted in the software world recently.

if the customer has ambiguity in his vision of the final outcome, it is highly likely for the project to get off the agile thought process had started early in the software development and started becoming popular with time chapter 4 agile development software engineering: a practitioner’s approach, 6th edition by roger s. pressman 1, . “agile process model” refers to a software development approach based on iterative development. each iteration involves a team working through a full software development life cycle including planning, requirements analysis, design, coding, and testing before a working product is demonstrated to the client.

agile software engineering combines a philosophy and a set 1. our highest priority is to satisfy agile software engineering combines a philosophy a set of development guidelines software engineers and other the agile process flow concept – projects are envisioned and prioritized,
