What is Method Waterfall?
Waterfall methodology is a traditional approach to software development that was widely used in the early days of software development. The waterfall model has a structure similar to that of a waterfall, where the output of each stage flows into the next stage in a sequential fashion.
The waterfall model consists of several phases, including requirements gathering and analysis, design, implementation, testing, and maintenance. Each phase must be completed before moving onto the next, and any changes made during one phase are difficult and expensive to make once the project has progressed.
The waterfall model is typically used for large projects with clearly defined requirements, where there is little chance of the requirements changing during the development process. The advantage of the waterfall model is that it is easy to understand and manage, and it provides a clear structure for the development process.
However, there are also several disadvantages to the waterfall model. For example, it is less flexible than other development methodologies because it is difficult to make changes once the project has progressed beyond a certain point. Also, the sequential nature of the waterfall model can lead to long development times and increased costs.
Despite its limitations, the waterfall model is still used today, often in combination with other methodologies such as Agile or DevOps. The waterfall model can be an effective approach for certain types of projects, but it requires careful planning and management to be successful.
Frequently Asked Questions about method waterfall
Waterfall Software Development Life Cycle
- Requirements & Documents. First, you must gather all the requirements and documentation you need to get started on the app.
- System Design. Next, you can begin planning the project proper.
- Implementation.
- System Testing and Deployment.
- Verification.
- Maintenance.
- Pricing.
- Connectivity.
One of the most common types of waterfall projects, Examples of Waterfall Type Projects in Project Management, is construction projects. Construction projects are characterized by their linear and sequential nature, where each phase must be completed before moving on to the next.
Waterfall is a linear project progression, so it's best suited for projects with a defined end goal. If a project owner has a clear and specific vision of an app, for example, and is confident it will not change throughout the project development, Waterfall methodologies could be a good system to follow.
But generally, you can group the activities of the waterfall approach into five stages: planning, design, implementation, verification, and maintenance.
Waterfall is a long-term product development method characterized by linear sequential phases for planning, building, and delivering new features or products.
A product methodology or system development methodology is a “framework that is used to structure, plan, and control the process of developing an information system” (Software development methodology, 2010, ¶ 1).
Waterfall is particularly useful for large, complex projects with very specific and unchanging requirements. Development teams will be less resistant to detailed product requirements documents and design specifications since that's what's expected.
Toyota uses the waterfall method for software development – and now they're trying to figure out how to go Lean.
The 6 stages of the Waterfall project management methodology are requirements, design, implementation, testing, delivery, and maintenance.
Waterfall Marketing is a model for marketing planning and execution that follows more traditional lines. Linear and sequential, the process flows steadily downward, waterfall fashion, through set phases.
Waterfall Marketing Overview
This system follows a linear traditional process that flows downward through set phases - conception, information gathering, analysis, design, construction, testing, implementation, and maintenance.
Agile can help improve product quality, leading to improved CSAT and customer retention rates. For example, if a company uses agile to develop a new product, it will work in short sprints and get customer feedback early and often. The process can help ensure the product is high quality and meets customers' needs.

Waterfall relies on teams following a sequence of steps and never moving forward until the previous phase has been completed. This structure is suited to smaller projects with deliverables that are easy to define from the start.
It is not suitable for large projects with complex requirements. You cannot accommodate the change in requirements at any stage. It is difficult to identify the challenges and risks in the earlier stages. You can use the time for actual processes instead of investing it in the documentation.
The waterfall model is most commonly used in software engineering and product development, less often – in other projects and industries. Employ the waterfall model only if your project meets the following criteria: All the requirements are known, clear, and fixed. There are no ambiguous requirements.
