The process, with its lack of initial design and steps, is often criticized for its collaborative nature that focuses on principles rather than process.ġ. These sprints allow for bugs to be discovered, and customer feedback to be incorporated into the design before the next sprint is run. The work on these modules is done in weekly or monthly sprints, and at the end of each sprint, project priorities are evaluated and tests are run. Instead of a sequential design process, the Agile methodology follows an incremental approach.ĭevelopers start off with a simplistic project design, and then begin to work on small modules. When definition, not speed, is key to success.Īgile came about as a “solution” to the disadvantages of the waterfall methodology. When clients won’t have the ability to change the scope of the project once it has begun.ģ. When there is a clear picture of what the final product should be.Ģ. When should you use waterfall methodology?ġ. If the client realizes that they need more than they initially thought, and demand change, the project will come in late and impact budget. The plan doesn’t take into account a client’s evolving needs.

If bugs are written early, but discovered late, their existence may have affected how other code was written.Īdditionally, the temptation to delay thorough testing is often very high, as these delays allow short-term wins of staying on-schedule.ĥ. The whole product is only tested at the end. If a requirement error is found, or a change needs to be made, the project has to start from the beginning with all new code.Ĥ. However, if these requirements are faulty in any manner, the project is doomed.ģ. Waterfall methodology relies heavily on initial requirements. Once a step has been completed, developers can’t go back to a previous stage and make changes.Ģ.

In the case of employee turnover, waterfall’s strong documentation allows for minimal project impact.ĭisadvantages of the Waterfall Methodologyġ. They’ll have a definite idea of what their program will do in the end.ģ. They’ll have an idea of the size, cost, and timeline for the project. With the waterfall methodology, the client knows what to expect. Having such records allows for the ability to improve upon the existing program in the future.Ģ. The waterfall methodology stresses meticulous record keeping. There’s no room for change or error, so a project outcome and an extensive plan must be set in the beginning and then followed carefully.ġ. This means that as each of the eight stages (conception, initiation, analysis, design, construction, testing, implementation, and maintenance) are completed, the developers move on to the next step.Īs this process is sequential, once a step has been completed, developers can’t go back to a previous step – not without scratching the whole project and starting from the beginning. Much like construction and manufacturing workflows, waterfall methodology is a sequential design process. Today, we’re arming you with information about both waterfall and Agile methodologies so that you can make an informed decision as to what you think is best. Does it matter really? Doesn’t either way give you a product (or, well, a skinned cat)? And as anytime there are two ways to go about something, a debate rages about which is best. There are several ways to develop software, two of the most prominent methods being waterfall and Agile.

We’re simply applying this logic to software development.

There’s a saying that goes “there’s more than one way to skin a cat.” Fortunately for cats everywhere, we’re not going to skin one.
