Daily Scrum (DS)
14
• Daily Stand-Up meeting is time-boxed to 15 minutes facilitated by Scrum Master
• Only “committed” people are allowed to talk
• Every Team member reports to the team on:• What have you done since
yesterday?• What you will finish by
tomorrow?• What impediments you got on
your way?
Daily Scrum
Scrum of Scrum (SoS)
15
• SoS meeting is time-boxed to 15 minutes facilitated by Scrum Master
• The frequency for scrum of scrums meetings should be determined by the team
• One team member from each team is representing his or her entire team and reports to the rest on:
• What has your team done since we last met?• What will your team do before we meet again?• Is anything slowing your team down or getting in their way?• Are you about to put something in another team’s way?
Sprint Review Meeting (SRM)
16
• At the end of every Sprint the Team invites the PO to the SRM
• SRM is time-boxed to maximum 4h (2 week Sprint)
• Team demonstrates on the real Product the feature implemented during the Sprint and asks PO to accept it
• PO either accepts or rejects feature
Sprint Review
Sprint Retrospective (Retro)
17
• Second half of SRM team performs self-assessment
• Team applies “Inspect & Adapt” loop to figure out:• What went well?• What went wrong?• What key changes are
we going to apply at the next Sprint?

Creating an Effective Product Vision
24
Goal: To gain insight on the possible release dates and manage and prioritize
product scope (PO) Share product roadmap with teams and make sure that entire team
understands direction, goals and vision of the product teamFormat: RPSs are usually planned outside of a sprint (2 days) to guarantee 100% clear
mind and focus; PO prepares items (themes), writes them down on cards and sticks them to
the wall in the conf. room by product areas; PO presents the items to team and team estimates them with planning poker.Outcome: Shared clarity about the product future.

Release Postmortems (aka Bug Retrospectives)
27
Release postmortems are regular retrospective-format meetings focused on reviewing and understanding reasons for important bugs popped up after LIVE releases and serve as decision making for preventive actions + follow up to the actions agreed.Goal: improving overall quality of software releasesMeans: Analyze missed bugs / incidents occurred case per case (bug by bug,
incident by incident); Find root causes for the bugs missed (appear live after deployments); Put preventive actions in place (fix the cause not the effect); Understand overall defect rates trends (same, worse, better). Attendees: release management team
INVESTing into good User Stories
28
• Immediately actionable
• Negotiable• Valuable• Estimable• Sized to fit in• Testable
Backlog Grooming Sessions
29
Backlog Grooming Sessions (BGSs) are regular meetings that are held between Product and IT and are driven by PO.
Goal: be there earlier Means: by preparing better for future
Backlog Grooming Sessions
30
To have Less: Unknowns; Stressful and long SPMs with
“surprises”; Questions and impediments during the
sprints; Unplanned tasks; Technical ad-hoc decisions on the go; To have More: Time to think & prepare (solutions,
correct estimations, planning, …); Shared clarity on the future; Granular, INVEST stories by SPM; Value delivered; Identify problems... Estimate stories…
BGSs can be any combination of activities to: Look further… Shape stories … Break stories down … Improve stories… Clarify details of the stories...
