Scrum Framework is a simple yet effective guide for project management, generally used in Agile Software Development. It includes Scrum roles, events, artifacts, and rules which provide boundaries and guidance on how to use them. The key roles include Product Owner, Scrum Master, and the Development Team. Events include Sprint, Sprint Planning, Daily Stand-up, Sprint Review, and Sprint Retrospective. Artifacts include Product Backlog, Sprint Backlog, and Product Increments. Rules bind these constituents together and govern relationships and interaction between them.

A Sprint is a time-box of one month or less during which a finished, usable, and potentially releasable product Increment is created. Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint. Sprints consist of the Sprint Planning, Daily Scrums, the development work, the Sprint Review, and the Sprint Retrospective.

The Scrum Master is responsible for promoting and supporting Scrum. Scrum Masters do this by helping everyone understand Scrum theory, practices, rules, and values. They are servant-leaders for the Scrum Team. The Scrum Master helps those outside the Scrum Team understand which interactions are helpful and which aren’t. The Scrum Master helps everyone change these interactions to maximize the value created by the Scrum Team.

The Scrum Team consists of a Product Owner, the Development Team, and a Scrum Master. Scrum Teams are self-organizing and cross-functional. They choose how best to accomplish their work, rather than being directed by others outside the team. Having well-defined roles allows for greater flexibility and collaboration within the team. Each role has its own set of responsibilities but all work towards a common goal: the success of the product.

The Product Backlog is a list of functionalities, features, or requirements to bring the project from ideation to completion. The items on the backlog, often referred to as 'stories', are presented by the product owner and usually respect a prioritization that obeys the project's business value. Each item must be clear enough to be understandable by every team member. The backlog is a live document that is updated and reprioritized as project requirements change.

The Product Owner is one of the essential roles in the Scrum framework. This person is primarily responsible for managing the Product Backlog. They ensure that requirements are clear, prioritize tasks, decide on the deliverables for each Sprint, and work to optimize the value of the work the team performs. The Product Owner is usually the point of contact for the stakeholders and the communication link between the stakeholders and the Scrum team.

Scrum Events, also called Scrum ceremonies, are key activities carried out in each Scrum Sprint. They provide the framework for the team to get together and focus on the relevant tasks at hand. These events include the Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective. They are designed to enable transparency, inspection, and adaptability throughout the project lifecycle.

The Definition of Done is a shared understanding among the Scrum team about what it means for work to be complete. This includes the essential tasks associated with every backlog item, such as writing code, coding comments, unit testing, integration testing, design, release notes, etc. The Definition of Done provides a checklist that assures every task is performed for every backlog item, and it ensures transparency and quality control.

Scrum Artifacts are key tools used in Scrum to provide information, specifically valuable information that is crucial for the Scrum team to perform its tasks effectively. The main Scrum artifacts include the Product Backlog, the Sprint Backlog, and the Increment. These artifacts are related to transparency and offer valuable insights into the progress of the project being developed.

A Burn-down Chart is a graphical representation of work left to do versus time in Scrum. The outstanding work (or backlog) is typically on the vertical axis, with time along the horizontal. Burn-down Charts are a run chart of outstanding work and are useful for predicting when all of the work for a sprint or release will be completed. It provides the team with a graphical view of how quickly they are working through the Customer's User Stories, and shows how much work is left to be done.
