The competition between the Agile Scrum Vs Waterfall methodologies is one of the major problems of modern software development. Discussions on which method is preferable are ongoing. In Scrum Vs Waterfall some programmers prefer to use Waterfall; the others execute their projects in Scrum. So what is the difference between these two methodologies and what are their advantages and disadvantages?
The First Thing To Do Is To Find The Definitions Of The Agile Scrum Vs Waterfall Methodologies.
Scrum Vs Waterfall is also called the traditional methodology of Agile Software Development. This comes from the software itself. The methodology has several key features.
First, it is based on strict documentation. In Waterfall, all customer requirements are documented in paper or digital format at the beginning of the project. The customer does not participate in the software development process. The team shows him the final product only after doing it.
Waterfall is a sequential methodology. All Scrum Vs Waterfall projects have a number (usually – 5 or 7) of steps executed one after the other. The developers cannot go back to the previous phase of the work and fix something there, even though it is already finished. If developers want to change something in the original code of the product, they must rerun the project.
The test procedure in Waterfall is carried out at the final stage of the project. It is therefore impossible to detect bugs and problems in time and resolve them before delivery of the product to the customer.
In Scrum Vs Waterfall Scrum Is Based On Other Principles.
Like all Agile Methodologies, it is quite flexible. This means that Scrum projects do not have sequential steps or strict documentation. Let’s look at the basic principles of the Scrum methodology.
The first thing to mention is that Scrum projects are subdivided into iterative cycles called sprints. Each sprint lasts from 1 to 4 weeks. The average duration of the sprint is about 2 weeks. The team performs the tasks of the sprint backlog during this period. A sprint backlog is not a strict work plan defined in the early days of the project, but a result of the activities of the product manager.
The Product Manager in Scrum Vs Waterfall is a person responsible for collecting user stories and prioritizing them in the product backlog. The product book can be re-prioritized by the team to more effectively manage their work on the project. In fact, the Product Owner is the customer or his representative on the Scrum team. He participates in all team meetings because client participation is extremely important in Scrum.
In Scrum projects, In Scrum Vs Waterfall the intermediate of Agile product is testing after each sprint. This is why Scrum developers are able to detect most bugs and remove them before the software is delivered to the client.
Agile Scrum Vs. Waterfall Cycle Methodology
In Scrum Vs Waterfall So which methodology is the best? There is no appropriate answer to this question. However, the analysis of the two methodologies has shown us that Waterfall has many disadvantages.
