Waterfall development method

Waterfall methodology is a linear project management approach, where Client requirements are

gathered at the beginning of the project, and then a finalized project plan is created to reach those

requirements. The waterfall approach was conceived in 1970, by Winston W. Royce, and it was

quickly taken in by a variety of industries due to its logical sequencing and easily implemented

into the works of projects.

Many consider the waterfall method to be the go-to traditional software development method.

The waterfall method is a linear model that primarily consists of sequential phases (requirements,

design, implementation, verification, maintenance) focusing on precise goals. Each phase must

be 100% complete before the next phase can initiate. There’s usually no process for going

backwards to readjust the project or direction.

If the waterfall model is to be executed properly, each of the above phases must execute in a

linear fashion otherwise it fails. Each phase is to be completed before the next phase can begin,

and phases can never be repeated, unless there is a failure that happens during verification or

maintenance phase.

pros:

Early stages in the software production cycle can reduce costs at later stages. For example, a

problem found in the early on is cheaper to fix than the same bug found at the end in the process.

Waterfall methodologies result in a project schedule with 20–40% of the time invested for the

first couple phases, 30–40% to coding, and the rest to testing and implementing. The actual

project organization needs to be highly structured. Most medium and large projects will have

detailed set of procedures and controls, which regulate everything on the project.

Another pro is that the waterfall model places emphasis on documentation as well as source

code. In less thoroughly designed and documented methodologies, knowledge is lost if members

of the time leave before the project is finished, and it would prove difficult for a project to

recover from that. If a fully working design document is present, new team members or even

entirely new teams should be able to familiarize themselves by reading the documents.
