the traditional software development process is linear, with each stage of the lifecycle requiring completion of the previous stage. this concept works well when customer requirements remain static, but in practice, requirements change frequently and cause frequent editing of programs leading to errors and software ‘rot.’ extreme programming (xp) turns the traditional software development process sideways. the approach bears resemblance to a jigsaw puzzle with the development of many small pieces or iterations that make no sense individually, but making for a complete package when combined. the extreme programming software development process starts with planning, and all iterations consist of four basic phases in its life cycle: designing, coding, testing, and listening. the first phase of extreme programming life cycle is planning, where customers or users meet with the development team to create ‘user stories’ or requirements. a combination of iterations provides the customer with the final fully functional product.
one planning approach is the critical path method, grouping iterations essential for project progress in a linear fashion, and arranging for completion of other iterations parallel to the critical path. extreme program integrates testing with the development phase rather than at the end of the development phase. another key test is customer acceptance tests, based on the customer specifications. the basis of extreme programming is a continuous mechanism of customer involvement through feedback during the development phase. the basis of feedback is the customer acceptance tests. each feedback of the customer that specifies revised requirement becomes the basis of a new design, and the process of design-coding-tests-listening repeats itself.
the refactoring is the different way and methods of doing objects in programming. this is the first phase of the extreme programming life cycle, which involves user stories along with iterations. they are also called unit tests and the purpose of doing them is to remove bugs before the delivery.
to productively produce applications that will satisfy the client needs, software engineers must have a connoisseur understanding of their customersâ requirements in every user stories and it is vital to capture the whole story thoroughly from clients for every and each step. with the simple design, time is never wasted and it is simpler to grasp everything, which refactoring and cooperative possession are made possible. as it was mentioned earlier about refactoring, there is a practice called collective ownership, which allows refactoring and is the idea of code ownership for developers. extreme programming is self-control software development based on principles of courage, feedback, communication and the most important one, simplicity.
extreme programming is iterative and incremental and is driven by time-boxed cycles. therefore, the rhythm of the extreme programming process is crucial. product life cycle activities provide inputs for release cycles. release planning sessions provide inputs for iteration cycles. extreme programming life cycle consists of planning, designing, coding, testing, all codes have unit tests to extreme programming (xp) xp’s life cycle stages planning designing coding testing listening importance of, . extreme programming is a popular agile methodology of software development. extreme programming life cycle is the time required to perform a typical xp project. it begins at the stage of planning and ends when the final product is delivered to the customer.
extreme programming (xp) is an agile project management methodology that involves frequent management methodology that supports frequent releases in short development cycles to improve extreme programming (xp) is a software development methodology as a type of agile software development, it advocates they are named as -planning or implementing, drawing, coding experimenting, and listening. these phases are always,
