Basics of Scrum: History, Values, and Principles.

Scrum is one of the most popular ways to manage projects in the IT industry. It is based on certain rules that help the team be flexible, communicative and collaborate during development.

Scrum has 5 values that form the basis of team work:

1. Courage - not being afraid to take risks and make tough decisions.
2. Focus on goals - always directing the team towards achieving common goals.
3. Collaboration - creating a good atmosphere for communication and cooperation.
4. Self-organization - the team should be able to organize their work independently.
5. Simplicity - using simple and effective methods to solve tasks.

Scrum also has 12 principles that describe rules and approaches to development:

1. Transparency - everything should be open to all project participants.
2. Inspection - regularly examining the team's work and the project as a whole.
3. Adaptation - using the results of inspection to improve work.
4. Collaboration - the team working with the customer and other project stakeholders.
5. Focus on goals - the team should always be directed towards common goals.
6. Timeboxing - work should be done within certain time frames.
7. Iterations - the development process should take place through a series of short cycles.
8. Sprint - the main element of the iterative development process.
9. Product backlog management - managing the team's work based on a list of tasks and priorities.
10. Teamwork - effective interaction and collaboration within the team.
11. Process improvement - the team should always strive to improve their work process.
12. Risk-taking - the team should be willing to take risks and try new approaches to development.

How to Work in Scrum

In Scrum, we work step by step, starting with the product backlog, where all the tasks and their priorities are listed. A sprint is a short period of team work that can last from one to four weeks. It's important to choose the right sprint duration, and usually it's one week. But of course, it all depends on the project we're working on and the tasks we need to solve.

At sprint planning, the team selects tasks from the product backlog that will be completed during the next sprint.

Every day at the Daily Scrum, the team discusses the current status of the project and progress.

At the sprint review, the team demonstrates the results of their work and receives feedback from the customer and other stakeholders.

And at the sprint retrospective, the team discusses what was good and what could be improved in the work, and determines what steps need to be taken to improve the process.

Why Scrum is Better

Scrum is the best choice if we want the project to go smoothly. It offers us many advantages over traditional development methods.

• Scrum gives us flexibility, which allows us to quickly adapt to changing customer and market requirements.
• Scrum ensures high product quality through regular inspections and process adaptation.
• Scrum helps improve communication within the team and with the customer through regular meetings and demonstrations.
• Scrum enables us to work more efficiently by providing clear sprint goals and constraints, which helps avoid wasting time on ineffective work.
• Scrum helps the team work openly and transparently, improving communication and avoiding conflicts.

Scrum is a cool thing in development that helps the team work better and faster. It defines roles in the team, such as the Scrum Master, Product Owner, and Team.

The Scrum Master is not a boss, but ensures that the Scrum process works as it should. The Product Owner is responsible for ensuring that the team works on the right tasks and that the product meets customer requirements. The Team is just a group of awesome people who work together to get the job done as cool as possible.

Scrum also includes several events during each sprint.

For example:

• Sprint Planning - when the team plans what needs to be done.
• Daily Scrum - a daily meeting where the team discusses their progress and resolves obstacles.
• Sprint Review - when the team looks at the work they have done and showcases the results.
• Sprint Retrospective - an analysis of the team's work to find ways to improve the process.

And the coolest thing is that Scrum is not just for IT professionals! It can be used anywhere - in marketing, business, education, and even in personal life. With Scrum, communication can be improved, development time can be reduced, and product quality can be improved. That's why many companies and organizations use this methodology.

In general, Scrum is a great tool that helps to work more efficiently.
