In Kanban, when a task is in the "Done" column, it means that the task is completed and ready for deployment. This signifies that all the necessary work on the task has been finished, and it's now ready to be delivered to the customer or integrated into the product.

The main difference between Kanban and Scrum boards lies in their approach to workflow management. Kanban boards emphasize continuous delivery, allowing tasks to be pulled as capacity allows, while Scrum boards operate within fixed-length iterations called sprints. This influences how work is planned, executed, and monitored throughout the development process.

The "Issue Type" field in JIRA is used to categorize the type of work being done or the nature of the problem being addressed. Common types include Task, Story, Bug, and Epic, which help in organizing and prioritizing work items effectively.

The "customer satisfaction survey" in JIRA Service Desk serves the purpose of gathering feedback from customers about their experience with the service desk. After an issue is resolved, customers may receive a survey asking them to rate their satisfaction with the support they received. This feedback helps organizations identify areas for improvement, measure customer satisfaction levels, and make informed decisions to enhance service quality.

In JIRA, custom issue types allow teams to tailor the platform to their specific workflows and requirements. These custom issue types can represent various tasks, bugs, or other work items that align with the team's processes and terminology. Custom issue types enhance flexibility and clarity in project management within JIRA.

In JIRA, transitions represent the actions that can be taken on an issue, such as moving it from one status to another. By configuring a transition, you can enforce a code review before transitioning an issue to the "Done" status. This ensures that code reviews are completed before code is considered finished and ready for deployment.

The Definition of Done (DoD) in Agile serves to clearly define when a user story or task is considered complete and ready to be shipped or released. It typically includes criteria such as code review, testing, documentation, and acceptance criteria. Having a well-defined DoD ensures that there is a shared understanding among the team members regarding the completion criteria for each task or user story.

Collaboratively re-prioritizing tasks allows the team to focus on completing the most valuable user stories within the Sprint, ensuring that they deliver incremental value to stakeholders. Extending the Sprint duration contradicts the time-boxed nature of Agile Sprints and can lead to other planning issues. Decreasing Sprint quality compromises the integrity of the product and violates Agile principles. Blaming the Product Owner is unproductive and undermines teamwork.

A "validator" in a JIRA workflow is a rule or condition that must be satisfied before a transition can be executed. Validators are used to enforce specific requirements or checks on an issue before it moves from one status to another. For example, you can use a validator to ensure that certain fields are filled out, or that certain conditions are met before an issue can be transitioned to a different workflow status. Validators help maintain data integrity and enforce workflow rules.

The Sprint Review meeting typically includes a demonstration of Stories completed during the Sprint. This demonstration allows stakeholders to see the tangible progress made by the team and provide feedback on the delivered increment. It helps ensure alignment with customer expectations and fosters transparency in the development process.
