Knowing the benefits and drawbacks of the Waterfall method can help you to recognize its value and when it’s best to use it. The Pros and Cons of Waterfall Project Management The customer is also provided with consistent support and maintenance for the developed software. The modifications are per the requests from the customer or any faults detected during the live use of the product. The maintenance phase involves making adjustments to the system to improve performance. The final phase happens after installation. Once the product has been tested, it is then distributed into the customer environment. The testing phase of Waterfall project management is imperative as it can ensure the customer is not confronted by any difficulties during the installation of the software. They are then integrated into the following phase.īy this phase, the software has been designed and needs to go through testing to determine any errors or issues. They are individually developed and tested for their functionality, a process that is known as Unit Testing. This phase is where the programs, which are known as units, are first developed. This is also when the software code that is written in the next stage is created. The purpose of this phase is to select hardware and system requirements and to also make clear the overall system architecture. This next phase involves creating the design according to the requirements of the first phase. Conducting brainstorming sessions are a common way to ensure the scope and requirements are understood by everyone on the team. The purpose of the product and its function is defined. The first phase is about collecting information that pertains to the project’s requirements. The most common model used is the following: Since then, there have been variations in the model depending on project context and requirements. In Royce’s original model, the phases are: You can only move on to the next phase once the current one is completed, reviewed, and approved. There are six phases within the Waterfall methodology. The Phases of Waterfall Project Management Thayer that the term may have been first used. It wouldn’t be until 1976 when a paper was written by T.E. Royce in 1970, however, the term “Waterfall” wasn’t used. It was first formally introduced as a method for software development in an article written by Winston W. (Think about it, once you construct a building, it would be pretty difficult to go back and make changes.) Due to the structured physical environments, the process leaves little room for changes as any changes made would result in high costs. The Waterfall methodology has its origins within the manufacturing and construction industries, to which you could ascribe its stringent process. The History of Waterfall Project Management Known for their emphasis on documentation, Gantt charts and resource scheduling and allocation are popular Waterfall project management tools. It follows a linear, sequential design approach where progress flows downwards in one direction, like a waterfall (hence the name!).Ī project is delivered through a set of ordered stages and until all activity within the current stage has been completed and approved, advancing to the next stage or any later stages is not possible. Waterfall project management is one of the more traditional software development methodologies.
