The best way to estimate Product Backlog Items (PBI) is in story points, while Sprint Backlog Tasks should be assessed in hours.

User stories, use cases and features are higher-level items and are usually estimated in story points, not in hours.

However, story points are less effective at the Sprint level. During Sprint Planning, the goal is for the team to commit to a realistic amount of work. Abstract units like story points make this difficult, whereas hours provide a concrete way to gauge capacity and ensure feasibility.

True Leadership in Scrum: Servant Leadership + Empowerment

Scrum redefines leadership as facilitation, not control, supports both team-level and organization-level Scrum adoption and it maintain team self-management while providing guidance. It’s not about authority, but about enabling teams to self-organize, innovate, and deliver value fearlessly.

A great leader cultivates skills, removes obstacles, and leads by example, building trust that drives both team and organizational success.

True leadership in Scrum isn’t a role—it’s a behavior. The best leaders measure their success by how little they’re needed.

Daily Scrum Participation Rules

1. Required Attendees:
   • Developers (the only mandatory participants)
   • Optional but recommended: Product Owner & Scrum Master
2. Observer Policy:
   • Stakeholders (e.g., product managers, clients) may attend only if:
     • Invited by the team
     • Remain silent observers (no comments/questions during the meeting)
3. Core Principles:
   • Developer-Led – The team (not SM/PO) runs the meeting.
   • 15-Minute Timebox – Focus: "Are we on track to meet the Sprint Goal?"
   • No Side Discussions – Off-topic conversations happen afterward.

Kanban and Scrum are project management methodologies that complete project tasks in small increments and emphasize continuous improvement. But the processes they use to achieve those ends are different. The fundamental difference is that Scrum provides a more prescriptive framework with defined roles, events, and artifacts, while Kanban offers a more flexible approach focused on visualizing and optimizing flow without prescribed roles or timeboxes.

Methodology comparison between Kanban and Scrum:

1. Roles:
   • Kanban focuses on workflow rather than role definitions.
   • Scrum clearly defines 3 roles: Scrum Master, Product Owner, and Developers.
2. Delivery cycle:
   • Kanban is continuous.
   • In Scrum, the Sprint cycle lasts one to four weeks.
3. Change policy:
   • For Kanban, changes can be incorporated at any time.
   • In Scrum, changes are generally not made during the sprint.
4. Artifacts:
   • Kanban uses a Kanban board.
   • Scum has Product backlog, sprint backlog, and product increments.
5. Tools:
   • Kanban uses Jira Software, Kanbanize, SwiftKanban, Trello, Asana.
   • Scrum uses Jira Software, Axosoft, VivifyScrum, and Targetprocess.
6. Key concepts or pillars:
   • Kanban is about Effectiveness, efficiency, and predictability.
   • Scrum is about Transparency, Adaptation, and Inspection.
