waterfall development process

if this is not something you’ve worked with before, a definition of development methodology is in order; put very simply, it’s a way of organizing the work of software development. this is not about a style of project management or a specific technical approach, although you will often hear these terms all thrown together or used interchangeably. having been involved in software development projects for a long time, here are my thoughts on the strengths and weaknesses of each. there is also typically a stage gate between each; for example, requirements must be reviewed and approved by the customer before design can begin. this approach emphasizes the rapid delivery of an application in complete functional components. if all planned work for the sprint cannot be completed, work is reprioritized and the information is used for future sprint planning.

agile relies on a very high level of customer involvement throughout the project, but especially during these reviews. first, we change the game a little (which is what most software development organizations do) by defining our own process. our modifications include use of prototyping where possible to provide the customer a better view of their finished product early in the design/development cycle. after the primary framework of the application is completed per high level requirements, we continue to develop and also to reach out to the customer for refinement of requirements. although we are starting to see mass adoption of various agile methodologies in the enterprise (even dod and federal agencies), there are still many organizations that are slow to make the change. it is also very common for organization to transition into more of a hybrid agile approach that combines aspect of both agile and waterfall. the project management institute (pmi) that developed the project management body of knowledge (pmbok) guide collaborated with the agile alliance to bundle the two guides in one offering to help organizations, managers and leadership increase agility in the development process.

the waterfall model was the first process model to be introduced. in a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. in “the waterfall” approach, the whole process of software development is divided into separate phases. the waterfall model is a sequential design process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, production/implementation, and maintenance.

as the waterfall model illustrates the software development process in a linear sequential flow; hence it is also referred to as a linear-sequential life cycle model. the next phase is started only after the defined set of goals is achieved for the previous phase and it is signed off, so the name “waterfall model“. currently i am working with knab bank as sdet. i am passionate about designing automation frameworks that follows oops concepts and design patterns. i live in amsterdam(nl), with my wife and a lovely daughter.

the waterfall model is a breakdown of project activities into linear the waterfall development model originated in the the waterfall methodology. waterfall is a linear approach to software development. in this methodology, in “the waterfall” approach, the whole process of software development is divided into separate phases., waterfall model, waterfall model, agile methodology, waterfall methodology vs agile, waterfall model example. the waterfall methodology\u2014also known as the waterfall model\u2014is a sequential software development process, where progress flows steadily toward the conclusion (like a waterfall) through the phases of a project (that is, analysis, design, development, testing). the disadvantage of waterfall development is that it does not allow much reflection or revision. once an application is in the testing stage, it is very difficult to go back and change something that was not well-documented or thought upon in the concept stage. the waterfall model is a breakdown of project activities into linear sequential phases, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. the approach is typical for certain areas of engineering design.

simply put, waterfall project management is a sequential, linear process of project management. it consists of several this method was originally defined by winston w. royce in 1970, (“the waterfall development methodology”, 2006). some of the industries that regularly use the waterfall model include construction, it and software development.,
