3.3.2. review of day before (results, problems, need to re-plan/change)

3.3.2.1. = inspect progress toward the Sprint Goal and how progress is trending toward completing the work in the Sprint Backlog

3.3.3. plan for the coming day

3.3.4. structure set by the Development Team and can be conducted in different ways

3.3.4.1. questions and/or discussions

3.4.3.2. Product Owner: -discusses Prod.Backlog as is - projects likely targets and delivery dates

3.4.3.3. together: - what to do next - review of marketplace / potential use changes - review of timeline, budget, potential capabilities, and marketplace for next anticipated releases of functionality or capability

3.4.4. output

3.4.4.1. revised Product Backlog - defined probable Product Backlog items for the next Sprint

4. Artifacts

4.1. Product Backlog

4.1.1. Product Owner is only responsible person for it

4.1.1.1. orders items at will (suitable only for more efficiency)

4.1.1.2. tracks total work remaining at least every Sprint Review

4.1.1.3. compares progress made in current sprint with effort in prior sprints

4.1.1.3.1. transparent for all stakeholders

4.1.2. "living document"

4.1.2.1. single source of requirements for any changes to be made to the product

4.1.2.2. earliest development of it lays out the initially known and best-understood requirements.

4.1.2.3. evolves during product development

4.1.2.4. assists as long as product exists

4.1.3. features

4.1.3.1. ordered list of everything that is known to be needed in the product

4.1.3.1.1. Higher ordered items are usually clearer and more detailed than lower ordered ones

4.1.3.1.2. estimates only by Dev.Team

4.1.3.2. lists all features, functions, requirements, enhancements, and fixes that constitute the changes to be made to the product in future releases

4.1.3.3. items have the attributes of a description, order, estimate, and value. sometimes

4.1.3.4. sometimes items include test descriptions that will prove its completeness when "Done"

4.1.3.5. if multiple teams work: one Product Backlog with group attribute for items

4.1.3.6. refinement

4.1.3.6.1. act of adding detail, estimates, and order to items in the Product Backlog

4.1.3.6.2. collaborative, ongoing work of Prod.Owner and Dev.Team

4.1.3.6.3. consumes usually no more than 10% of the capacity of the Dev.Team

4.2. Sprint Backlog

4.2.1. set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal

4.2.1.1. with enough detail that changes in progress can be understood in the Daily Scrum

4.2.1.2. As new work is required, the Development Team adds it to the Sprint Backlog

4.2.2. forecast by the Development Team

4.2.2.1. As work is performed or completed, the estimated remaining work is updated

4.2.2.2. At any point, total work remaining in the Sprint Backlog can be summed

4.2.3. makes visible all the work that the Development Team identifies as necessary to meet the Sprint Goal

4.2.4. includes at least one high priority process improvement identified in the previous Retrospective meeting

4.2.5. Dev.Team is only responsible

4.3. Increment

4.3.1. sum of all the Product Backlog items completed during a Sprint and the value of all previous increments

4.3.2. body of inspectable, done work that supports empiricism = tested, useable and potentially releasable

4.4. transparency

4.4.1. Decisions to optimize value and control risk are made based on the perceived state of the artifacts.

4.4.2. Scrum Master's role to improve transparency

4.4.2.1. must help Scrum Team with practices for coping with incomplete transparency

4.4.2.2. work with the Scrum Team and the organization to increase the transparency of the artifacts

4.4.3. definition of "Done"

4.4.3.1. everyone must understand what "Done" means (what it means for work to be complete)

4.4.3.1.1. If definition of "Done" is part of conventions, standards or guidelines of the development organization, all Scrum Teams must follow it as a minimum.

4.4.3.1.2. if multiple Scrum Teams: all Development Teams must mutually define the definition of "Done".
