Which two roles are necessary to build an effective workspace-level team in Slack?

To build an effective workspace-level team in Slack, having workspace owners and admins is essential. Workspace owners are responsible for the overall management and configuration of the Slack environment, including permissions, integrations, and workspace policies. They have the authority to make high-level decisions that affect all members and channels within the workspace.

Admins work closely with the owners but typically focus on day-to-day operations, such as managing users, monitoring activity, and facilitating communication across different teams. Together, owners and admins ensure that the workspace is organized, secure, and tailored to meet the needs of its users, which is critical for fostering collaboration and productivity.

The other options, while they may include roles that contribute to teamwork in various contexts, do not encompass the overarching responsibilities and powers necessary to maintain the structure and integrity of a Slack workspace. Roles like moderators or channel managers provide support within specific contexts, but they lack the broader authority and strategic overview that owners and admins possess.
