[OA.BCL.8] Determine team sizes based on cognitive capacity

Category: FOUNDATIONAL

Determine team size using Dunbar's number and the 7 ± 2 rule, which state that teams should be composed of no more than 7 to 10 individuals. With smaller teams, they require the autonomy and resources necessary to be successful within their value stream. Keep team sizes manageable, and foster effective communication, collaboration, and decision-making. Regularly assess the team's composition and structure, making adjustments as needed to maintain efficiency and effectiveness. Provide teams with the necessary tools and resources to support collaboration and communication in small group settings.

Larger organizations might have teams of teams, often referred to as guilds, chapters, or squads. The name used here is completely dependent on the organization's preference and culture. In this scenario, Dunbar's number advises that the number of people not exceed 150. Having a team of teams allows smaller teams to work together towards common goals that align to related business outcomes, while maintaining the benefits of smaller team sizes and scaling effectively within a larger organization.
