An effective engineering team is
   highly collaborative, focused on delivering
     high quality code with velocity.

The team
  sets the standard for other teams to follow in how they
    design software,
      write and test their software and
        ultimately delivering business value to the customer.

The team functions as a
  coherent group,
    helping each other succeed, having a
      sense of ownership for the product and code.

They actively take
  ownership of the product backlog,
    pays down tech debt and
      communicate outwards to their stakeholders.
