What is a waterfall diagram?
A waterfall is a process model that allows users to have a guide line to a system analyses. It allows you to see what steps you have to take and in so you can find the requirements and develop a new system that will meet these requirements. This waterfall diagram, shown below, helps you see each stage that is required to be completed in this approach. This process is used when carrying out system analysis.  It allows the team to have an order to work with. This process is mainly used in upgrades as it allows the analysts to see their progress. The advantages of using this process is that you can have a guide for carrying out system analyse and how you should proceed in the development of new software. One of the main benefits of this process is that it allows you to focus on one stage at a time allowing for better time management among the team. This is also good for workers with little experience as they can focus on one stage at a time and take time

Figure 1 below shows the main stages analysts follow in the Waterfall method. The analysis stage is carried out to see if it is feasible for the project to continue then there is the requirement specification which is what the client needs the system to do. After that there is the design stage, this is where the team will design the new system. This will allow for a set plan for the forthcoming steps. The development process is where the developers will use the design from the previous stage to develop the new system using programming software, such as C#.. The testing stage is next where they will take the new system and test it to make sure there are no problems with it. The last stage is where they will install the software into the clients business. Often they will then maintain the system for while in case there are any issues with it.
