The waterfall methodology is a framework used in software development where phases are established sequentially to make up the whole process. The model hopes to specifically define the milestones of each phase, the goals of the process, and the actual date of the product release.
The manufacturing and construction industries first utilised the model back in the 1970s, where hardware products were manufactured. Since the other business industries have seen how effective the system was at saving money and addressing possible problems, the software sector saw fit to adapt the system to their own wants and needs.
The waterfall methodology's phases are explained, as follows:
Requirements analysis. Clients' needs and requirements are the primary concern of this phase. Some of the tools used in this phase include customer interviews and use cases.
Design. During this phase, the architecture of the product (hardware and software) are established, along with the parameters for security and performance, storage constraints for data, programming language and the IDE, and others. The user interface that will be used in sorted out in this phase, too.
Implementation. The team will begin constructing the product during this phase, following the specifications set forth by the earlier phases. This phase will also address the division of labor between designers, programmers, compilers and others.
Testing. Testing takes care of ensuring that the product is built accordingly and functioning well so that customers' needs may be truly met. It's handled by a Quality Assurance team.
Installation. The clients get the software product during this phase. Sending the product through the Internet or physical media is usually how the product is released to the customers.
Maintenance. In this phase, the errors and bugs that the product came with would be sorted out by the team. When the team makes changes to the product, too, a new version of the product is released to the client to make sure that he or she would be able to enjoy the changes.
Since every organization is different, the structure is different, etc. the needs are different as well. There are alternatives to the Waterfall methodology-the Agile, for example, has got fairly popular recently-and you may find out that they suit you better. Do your research, consult others who have experience with these and do the right thing.
