Scrumban
Scrumban is a management framework that integrates Scrum practices with Kanban principles to improve team workflow and operational efficiency. It emphasizes lean principles, such as eliminating waste, empowering teams, and maintaining a prioritized backlog to ensure timely delivery and adaptability. The framework accommodates continuous flow and on-demand planning, allowing teams to dynamically manage tasks based on project needs and priorities.

Scrumban Management Framework ScrumKanban Scrumban Scrumban is a management framework that emerges when teams employ Scrum as their chosen way of working and use the Kanban Method as a lens through which to view, understand and continuously improve how they work Scrumban was created as an attempt to make it easier for existing Scrum teams to begin exploring Lean and Kanban concepts.

- 5. Lean Principles 1 Eliminatewaste • Partially done work • Extra processes • Extra features • Task switching • Waiting • Motion • Defects • Management activities Amplify learning • learning process • short iteration cycles • Refactoring • integration testing • Short Feedback Sessions
- 6. Lean Principles 2 Decideas late as possible • uncertainty • options-based approach • delaying decisions • uncertain assumptions • customers realize needs better Deliver as fast as possible • small iterations • without major defect • Feedback for next iteration • With speed, decisions can be delayed • until gain better knowledge Empower the team • Managers tell the workers • how to do • Roles are turned • Developer not resource • No disturbe • motivation • higher purpose
- 7. Lean Principles 3 Build IntegrityIn • Free from “flaw”: prioritized Product Backlog • Free from “defect” TDD • Free from “decay” Refactoring See the whole • root causes of defects • should be found • and eliminated • Think big • act small • fail fast • learn rapidly
- 8. Just In Time-Software Development This requires transparency of the process, which is also beneficial for team communication. and prompts for any inputs needed from colleagues or the customer. what is to be done today and tomorrow, each member of the team reviews what has been done yesterday, each morning during a stand-up meeting, Thus the work organization changes into self-pulling system the developers estimate the time needed for the implementation of each card. This could be simply presented in small cards or stories At the beginning, the customer provides the needed input. team organize itself and divide the tasks for accomplishing the needed result for a specific iteration. This is achieved by presenting the needed result

- 15. moving theplans through a few steps, Three buckets 1-year bucket is dedicated for long-term goals that the company has, like penetrating a new market, releasing new product 6-month bucket the main requirements of this plan are crystallized 3-month bucket clear tasks to be completed by the project team Methodology- Bucket size planning
- 16. To Do:Adding the tasks after planning Doing: Team member ready to work on the task move it to this section Done: after finish Definition of Done Visualize process The most common add-ons include priority columns in the To Do section and columns like Design, Manufacturing, Testing in the Doing section. Methodology- The Board
- 17. Team membershould be working on no more than one task at a time To make sure this rule is followed Scrumban uses WIP (work in progress) limit. This limit is visualized on top of the Doing section In order to have more productive planning meetings the number of tasks in the To Do section can be limited as well Methodology- The Board -2
- 18. Methodology- The Team No need for specific number of team members Each team member chooses which task from the To Do section This guarantees a smooth process flow, where all the team members are equally busy at all times
- 19. Methodology- Feature freeze Feature freeze is used in Scrumban when the project deadline is approaching. It means that only the features that the team already has for development can still be worked on and no additional features can be added
- 20. Methodology- Triage Triageusually happens right after feature freeze. With an approaching project deadline the project manager decides which of the in-development features will be completed and which will stay unfinished. This guarantees that the team can focus on finishing important features before the project deadline and forget the less important ones
