    Interaction mode:
    X-as-a-Service
    Interaction mode:
    Facilitating
    Interaction mode:
    Collaborating
    Primary interaction modes for the 4
    fundamental team topologies:
    Collaboration: working closely
    together with another team
    X-as-a Service: consuming or providing
    something with minimal collaboration
    Facilitating: helping (or being helped
    by) another team to clear impediments
    Evolution of team topologies
    Discover Establish Use
    Stream-Aligned Team: a
    team aligned to the main
    flow of business change,
    with cross-functional skills
    mix and the ability to deliver
    significant increments
    without waiting on another
    team.
    Platform team: a team that works on the
    underlying platform supporting stream-aligned
    teams in delivery. The platform simplifies
    otherwise complex technology and reduces
    cognitive load for teams that use it.
    Enabling team: a team that assists other teams
    in adopting and modifying software as part of a
    transition or learning period.
    Complicated-Subsystem Team: a team with a
    special remit for a subsystem that is too
    complicated to be dealt with by a normal
    stream-aligned team or platform team.
    Optional and only used when really necessary.
    Conway’s law: “Organizations which design
    systems … are constrained to produce designs
    which are copies of the communication structures
    of these organizations.”
    Cognitive load: “The total amount of mental effort
    being used in the working memory.” Restrict team
    responsibilities to match the maximum team
    cognitive load.
    • Intrinsic cognitive load – relates to aspects of the
    task fundamental to the problem space
    • Extraneous cognitive load – relates to the
    environment in which the task is being done
    • Germane cognitive load – relates to aspects of
    the task that need special attention for learning
    or high performance
    Scaling teams: Organizational groupings should
    follow Dunbar’s number, beginning with around 5-
    8 people, then increasing to around 15 people,
    then 50, then 150, then 500, and so on.
    Brook’s law: “Adding new people to a team
    doesn’t immediately increase its capacity.:
    Live
    Rapid
    feedback
    Team first approach: start with the team for
    effective software delivery. There are multiple
    aspects to consider and nurture: team size, team
    lifespan, team relationships, and team cognition.
    Organizational sensing: expect to adapt and evolve
    your organization structure.

    X-as-a-Service
    Interaction mode:
    Facilitating
    Interaction mode:
    Collaborating
    Primary interaction modes for the 4
    fundamental team topologies:
    Collaboration: working closely
    together with another team
    X-as-a Service: consuming or providing
    something with minimal collaboration
    Facilitating: helping (or being helped
    by) another team to clear impediments
    Evolution of team topologies
    Discover Establish Use
    Stream-Aligned Team: a
    team aligned to the main
    flow of business change,
    with cross-functional skills
    mix and the ability to deliver
    significant increments
    without waiting on another
    team.
    Platform team: a team that works on the
    underlying platform supporting stream-aligned
    teams in delivery. The platform simplifies
    otherwise complex technology and reduces
    cognitive load for teams that use it.
    Enabling team: a team that assists other teams
    in adopting and modifying software as part of a
    transition or learning period.
    Complicated-Subsystem Team: a team with a
    special remit for a subsystem that is too
    complicated to be dealt with by a normal
    stream-aligned team or platform team.
    Optional and only used when really necessary.
    Conway’s law: “Organizations which design
    systems … are constrained to produce designs
    which are copies of the communication structures
    of these organizations.”
    Cognitive load: “The total amount of mental effort
    being used in the working memory.” Restrict team
    responsibilities to match the maximum team
    cognitive load.
    • Intrinsic cognitive load – relates to aspects of the
    task fundamental to the problem space
    • Extraneous cognitive load – relates to the
    environment in which the task is being done
    • Germane cognitive load – relates to aspects of
    the task that need special attention for learning
    or high performance
    Scaling teams: Organizational groupings should
    follow Dunbar’s number, beginning with around 5-
    8 people, then increasing to around 15 people,
    then 50, then 150, then 500, and so on.
    Brook’s law: “Adding new people to a team
    doesn’t immediately increase its capacity.:
    Live
    Rapid
    feedback
    Team first approach: start with the team for
    effective software delivery. There are multiple
    aspects to consider and nurture: team size, team
    lifespan, team relationships, and team cognition.
    Organizational sensing: expect to adapt and evolve
    your organization structure.
