This is a simple one page aide memoire that can be used to help explain the responsibilities of the role of Product Owner and Scrum Master. It's great to print off and hand out to people when you are explaining what the roles are and what the differences are between them. So next time you need to talk about these roles, you can use this as a basis for a simple discussion or presentation.

 

Scrum Master's Responsibilities

  • Responsible for helping the team deliver work to the Product Owner
  • Makes sure the team can meet its commitments by removing any impediments they face, including Managing dependencies, escalating blockers that they cannot remove themselves
  • Facilitates process & meetings (eg Reviews, Stand Ups, Planning, Estimation, Scheduling, Prioritization)
  • Makes sure the team is fully functional, productive and improving quality
  • Shields the team from distractions and interferences (including the Product Owner)
  • Enables close co-operation across all roles and functions, removes barriers
  • Responsible for reporting progress, including producing standard outward-facing artefacts
  • Manages Product Owners expectations of the team
  • Responsible for keeping time and quality requirements

 

Product Owner's Responsibilities

  • Manages stakeholder relationships, comms & expectations

This is a good thing to help people in and out of these roles to get familiar with them. Nice!

I wonder about the first bullet where-in the Scrum Master delivers work to the Product Owner. I don't understand what that means. Could you elaborate your meaning and intention on that point?

Love usefull summaries like this to check what i thought I knew! I would have had the team for the first point of ScrumMaster, as they are committed to delivering the sprints work? Also I would have had the PO ideally responsible for keeping quality requirements (or a specialist supporting the PO in the team) as part of backlog grooming activities; in practise though this often falls to the ScrumMaster...

A couple of the responsibilities of the ScrumMaster don't make too much sense. Especially the "bringing the work to the PO" doesn't make any sense to me. Could you clarify what that means.

Also, usually the team is responsible for meeting the quality criteria and not the ScrumMaster. I'm unclear what meeting the time criteria means as sprints are timeboxed...

Useful article but I don't agree with statement that SM is "Responsible for delivering work to the Product Owner". SM is only a facilitator and actual TEAM is responsibile for delivering work to the PO. On the same note SM is NOT "Responsible for keeping time and quality requirements" it's team who is responsibile for keeping time (i.e. commitment) and quality requirements.

Also, what do you mean by "Manages Product Owners expectations of the team"? It should be "Correct Product Owners expectations of the team" to make sure PO is being reasonable to team when s/he is too demanding.

Looks IMO you focused only in Scrum Pratices. I mean, it's still missing all the "work" SM must do in order to coach the principles. From my daily work, this is the "heaviest" workload :) or at least where I feel I need to invest more and more! Cheers, Catia
