This post is in addition to core Scrum, and is my opinion on how to help boot up Scrum in a company as an Agile business process trainer, consultant, and coach:
The Executive Action Team is the first Scrum team I recommend to launch during an Agile transformation. The second is Human Resources, then a delivery team. The Executive Action Team is responsible for removing impediments to Scrum across the organization, which whittles away or blasts away the organizational debt preventing a low cost of change across the company. They quite literally exist to eat impediments to organizational agility. They MAY also be the Meta Scrum team, but this is not required. The Meta Scrum team has an equally important output of a single, prioritized, estimated, Meta Scrum backlog with labeled business value, from which all the other Product Owners pull, which quite literally determines the entire course of what gets done and in what order across any Scrum teams in the business.
The executive sponsor for the agile transformation is typically the Product Owner of this team, and ideally they are a member of the company board of directors if the impact of Scrum is intended to be enterprise wide. This team then includes a Scrum Master, often an expert executive assistant who knows how to navigate the company staff, and 2 to 3 members of senior staff as development team members. The backlog for this team is composed of the yet-unsolved impediments from ALL teams brought up through Scrum of Scrums, and a card which repeats every sprint to refine and prioritize the company master backlog from which all Scrum team Product Owner’s pull during the Meta Scrum. The development team members of the Executive Action Team are typically in the Product Owner role of teams that pull from the Master Backlog. These team demos back to the company on a sprint cadence, showing the resolution to any completed impediments and the current prioritization of the Master Backlog. This demo responsibly replaces the need for most types of all-hands meetings and mass-mailings. This demo also responsibly serves as a board of advisors meeting, and the Scrum Master is able to document meeting minutes as may required by the company’s articles of incorporation.
