![]() ![]() Customers are also updated on the latest technologies and can be confident that their product is ahead of the trend and can attract the end users.Ī team leader is usually present in teams that use the agile method.The team leader usually holds the teams together and can push collaboration between the teams, and between the team and the customer. Agile model encourages testing and evaluating so there are less errors in the final product, and makes sure that customers are satisfied with the project outcome as their inputs are needed in every stage of the development process.īy including the customers in the development process, they can have a better sense of what the product outcomes are going to be, and a better sense of ownership as they actively participate in the development process. ![]() It is usually used for more complicated, large projects where more advanced technologies are used. This makes it much harder for developers to change according to the customer’s will as this most likely means that the project has to be restarted and executed all over again.Īgile model is created to build the “perfect software” for clients. Since the customer is only involved in the planning and the delivery stages, there is a potential that the final product cannot satisfy the customer. This makes it harder for developers to fix the errors that occur earlier in the process and might delay completion time, or even worse, makes the project more costly. In addition, once a stage is over, it is considered finished and it is much harder to revisit the previous stage in the future.Īnother point is that the testing is only done after the development stage is over. Since the team strictly follows the process set up during the planning stage, they will carry out all the tasks as planned instead of improvising or improving during the process. Once the design stage is over, it is much harder to apply changes to the project. ![]() If you are going to make a lot of changes or consider having a long-term project where technologies might change or be updated, this might not be the best method as the waterfall model is not adaptable to changes. The first thing you should consider before applying the waterfall model to your project is that it is not a very suitable method for large and complicated projects. The best advantage of this methodology is that you can expect a completed, working software at the end of the project and the delivery time is usually measured accurately with no delay. Furthermore, if staff change occurs in the middle of the process, it is easy to adapt the staff to the change as tasks can be handed over swiftly and without compromises on quality. The customer is only involved in the first and last stages this means that it is easier for developers to concentrate on their expertise and less time needed to review the project over and over again after each stage. Thanks to this, the waterfall method allows fastest delivery speed for all projects and works extremely well on smaller, less complicated projects. Progress is also easier to measure, as it is linear and moves from one stage to the next. Waterfall is a very straightforward model as developers and decision-makers agree early on in the development process, and expectation is transparent from start to finish. This model requires you to have specific conditions and goals for each and every part of the development cycle and makes sure that everything is ready for the next stage.
