Waterfall methodology is a linear project management approach, where stakeholder and customer requirements are gathered at the beginning of the project, and then a sequential project plan is created to accommodate those requirements. The waterfall approach was first conceived by Winston W. Royce in 1970, and it was quickly adopted in a variety of industries due to its logical sequencing and ease of implementation.
Some of the industries that regularly use the waterfall method include construction, IT and software development. However, the term “waterfall” is usually used in a software context, so the rest of this post will concern the waterfall model as it pertains to software development.
