Scrum is a framework that is actively used in project development. The principle of interaction between developers can be compared to a sports team that is actively preparing for a decisive battle. The team learns the basics of self-realization, solves problems, due to which it gains valuable experience and can apply it in the future.

The popularity of scrum is explained not only by its high efficiency, but also by its versatility. It is used not only in application development, but also in other projects that are completely different in their specifics. This is a universal platform for managing projects according to the equally well-known Agile methodology. Scrum developers, which are also participants, take on different roles, hold meetings, use various tools to organize and manage work.

To implement the framework, a cross-functional team of approximately 7 people is required. Its tasks include creating a product in iterations of a fixed duration, called sprints in scrum, lasting no more than 1 month. In addition, the structure of the framework has a number of important elements: roles, events, rules, and artifacts.

3 roles in scrum

Roles in scrum are an integral part of the framework and differ in:

• The product owner is a person who knows everything about the value of the business. They convey the needs of the customer to the developers and are responsible for user stories. The product owner also prioritizes the latter.
• Developers, in turn, are responsible for the technical part. Their peculiarity lies in cross-functionality, which directly depends on the field of work. Developers are responsible for the sprint backlog (pointed out below), quality compliance, plan adaptation according to the sprint goals. In addition, they retain individual expert areas of responsibility.
• The Scrum Master is responsible for communication. Their task is simple and difficult at the same time: to help the product owner and developers do their work with maximum efficiency. As a rule, communication between team members and beyond is carried out through scrum masters.

5 events in the scrum framework

The scrum framework has 5 events:

• Sprint is an event that carries barely a key role. It is at this stage that ideas acquire their value, a full cycle of work is carried out aimed at achieving the goals of the product. It includes sprint planning, daily scrum, sprint review and retrospective.
• Sprint Planning is a compulsory event for every developer. At this stage, each team member gets acquainted with the product, everyone can express their opinion, whereby the priorities and deadlines are determined.
• Daily Scrum is a daily event during the sprint, usually lasting up to 15 minutes. Its main purpose is to plan the daily work of developers, which includes discussing difficulties and explaining the user story. This is a mandatory event for developers, but optional for the scrum master.
• Sprint Review is a demonstration of the results of work, a product developed in a sprint. As a rule, this event occurs at the end of a sprint.
• Sprint Retrospective is an event designed to identify both errors in the project and in communication between team members. The main goals of the event: to improve interaction and work in general.

3 scrum artifacts

Essentially, artifacts is the work that needs to be done to complete a project or sprint. They allow you to maintain transparency of information for each developer of the scrum team. There are 3 main artifacts, as well as their components:

• The Product Backlog is what needs to be done in order of importance.
• The Sprint Backlog is all the scheduled tasks in the sprint. The artifact is obtained from another component – the product backlog – when planning a sprint.
• An increment is everything that was done from the product backlog during the sprint. In addition, it also includes increments from past sprints. At the end of the sprint, the new increment should work. A product backlog item is a piece of work that is divided into several small tasks that need to be completed during a sprint.

These are the basic rules of the scrum framework. They allow you to get maximum efficiency in your work. The framework clearly shows adaptability and customer focus, which are almost the key points in the modern IT-sphere.
