The Waterfall model, also known as linear sequential design, is a software development model. Just like the name suggests, the development flows only in one direction, which is downwards.<\/p>\n
<\/p>\n
According to Oxagile<\/a>, this sequential development ends up releasing a new software product. The key to this Waterfall Model\u2019s framework is that it proceeds with each requirement step by step and never goes backwards..<\/p>\n The linear sequential design follows a program full of activities that need to be accomplished correctly before moving on to the next one.<\/p>\n This won\u2019t allow you to leave any open stages because you won\u2019t be able to proceed to the next task. All of the phases are planned and designed beforehand.<\/p>\n I highly recommend you to watch this YouTube video<\/a>, that goes through the basics of this development model. This will help you understand all the aspects explained in the article. It\u2019s named \u201cWhat is Waterfall Methodology?\u201d and it is created by Project Management Software \u2013 Easy Projects.<\/p>\n <\/p>\n If you are still trying to understand how this software development model works, it is essential for you to get acquainted with all the steps that you will be required to pass before reaching the final result.<\/p>\n The most important thing you should keep in mind while going though this software development model is to have a clear vision of the project and to understand properly what you are aiming for.<\/p>\n The Waterfall Model is very useful and easy to follow, only if the idea and its stages are perfectly identified. According to a Tech Republic article<\/a>, the following are the phases to a successful development.<\/p>\n One of the first steps is brainstorming and defining a concept. Investigate the target briefly to get an idea of their needs and find out the perfect product.<\/p>\n Once you resolve all of those questions, you need to do an exhaustive research of the clients and customers that you will be directing to. Define your target and investigate what they need and where they are from.<\/p>\n Once you have your customer\u2019s area controlled, it is time to start designing. You will need to plan a strategy that solves each of the problems that are presented. Apart from that, you will need to program other aspects like the language.<\/p>\n The next step is to start constructing it. Once all the ideas are clear, you will be able to start with the next step, which is implementing the solutions to every stated problem and constructing the final product.<\/p>\n Once the construction part of the development is done, you should start testing it. Verify that it accomplishes all the requirements you named before. Also, check out if they are totally error-free.<\/p>\n There are three different types of testing that are usually put into practice. The first one is called unit testing of code modules<\/strong><\/em>, which makes sure that all the coding is properly set up.<\/p>\n Then you should proceed with the system testing<\/strong><\/em> and finally, the acceptance testing.<\/p>\n The next step is deployment<\/em><\/strong>. When you check and verify that everything is working properly, you will be able to install the final product. The last step is the maintenance of the software result you just created.<\/p>\n The Waterfall Model is well known for its multiple advantages when it comes to creating and developing a new software product from scratch.<\/p>\nThe different phases of the development<\/h2>\n
