The roles and responsibilities in the Objectives and Key Results (OKRs) process include the Program Lead Office (PLO), OKR Coach Community, Sponsor, and Leadership. The PLO oversees the roll out of OKRs, creating a Rollout Plan, managing internal stakeholders, and updating executives. The OKR Coach Community provides guidance to teams, helping them understand and execute OKRs effectively. The Sponsor, typically an executive, offers vital support to the PLO and helps in crafting the Rollout Plan. Finally, the Leadership has the responsibility to actively participate in drafting top-level OKRs and aligning their leadership style with the OKR process.
