Self-Organizing Teams refer to the concept where team members voluntarily undertake tasks, coordinate their efforts and distribute their workload among themselves without any external influence. Such teams have proven to be extremely productive as they have the freedom to choose the most beneficial path to goal completion. Each team member contributes to the decision-making process, fostering a sense of ownership and accountability. This significantly boosts team morale and work satisfaction, leading to higher product quality and lesser product development time.

Scrum Review and Retrospectives refer to two important meetings held at the end of each Sprint. A Sprint Review involves a demonstration of the product increment to the stakeholders to elicit their feedback and possibly influence future product development. A Sprint Retrospective, on the other hand, allows the Scrum Team to reflect on the completed Sprint and identify opportunities for improvement for the subsequent Sprints. Both these meetings are essential in maintaining transparency, fostering a culture of continuous learning and improvement, and ensuring high product quality.

Scrum ceremonies, also known as Scrum events, are set activities that provide the framework for teams to get work done in a structured manner, reduce regularity, and enable critical face to face communication. The main ceremonies are Sprints, Sprint planning, Daily Scrum, Sprint Review, and Sprint Retrospective. Each of these ceremonies are designed to maximize the amount of productive time to deliver valuable output.

Time Boxing is a concept used in Scrum to define a specific time period during which tasks need to be completed. Each Scrum event is timeboxed. The duration is fixed in advance and cannot be lengthened or shortened. Time boxes instill an understanding of the importance of respecting time and creates routine and predictability. They also allow the Scrum Team to effectively manage their work and provides regular opportunities for inspection and adaptation.

Scaling Scrum refers to the process of taking Scrum and applying it across multiple teams working on the same product. This may involve several Scrum teams working on the same product backlog, coordinating their efforts, and regularly integrating their work into the same potentially releasable Increment. This can be more complex and needs to be thoughtfully designed, so that scaling is beneficial and does not adversely affect the benefits Scrum can bring.

Backlog Grooming, also known as Backlog Refinement, is an ongoing process in which the Product Owner and the Development Team collaborate to ensure that the Product Backlog is regularly updated and prioritized. During this process, they review backlog items to ensure the team is working on the highest-value features and tasks. Backlog Grooming allows the team to estimate effort, make a clearer understanding of backlog items, and align the work with the product goal and objectives.

A Sprint Burndown Chart is a visual measurement tool that shows the completed work per day or sprint against the projected work rate for a scrum team. The chart is updated daily throughout the sprint, and it gives the team a real-time snapshot of their work. This helps teams manage their progress and respond accordingly to any changes, maintaining a steady, sustainable pace of work. It encourages transparency and helps identify potential issues early in the process.

The Definition of Done (DoD) is a comprehensive checklist of necessary functionalities and conditions that need to be met for a product increment to be considered 'production ready'. This includes the requirements from the product owner, as well as compliance standards, testing, documentation, and design or architecture standards. Each scrum team might have different DoDs, depending on the nature of the project. The accuracy and completeness of the DoD helps in ensuring high quality software.

The role of a Scrum Master is to ensure everyone on the team adheres to the Scrum theory, practices, and rules. They guide and coach the Scrum Team and the organization to understand and implement Scrum effectively. As a servant-leader, the Scrum Master assist the team in removing impediments that obstruct the achievement of the sprint goals. Scrum Masters facilitate Scrum events as necessary, protect the team from outside disruptions, promote good relationships among team members, and assist the product owner in maintaining a healthy product backlog.

In Scrum, work is typically measured in story points, which represent a high-level estimation of complexity and effort involved in a user story. Teams assign points based on factors like the complexity of the work, the effort it will take, and any uncertainty or risk involved. Over time, teams get better at estimating how many story points they can complete in a sprint (known as their velocity), which helps with future planning and forecasting.
