Shared Resources or Inaccessible Staff If those responsible for performing the work have multiple obligations and priorities that make them unavailable to do the work as soon as it arrives, this may present a significant barrier to flow. If staff is unavailable or inaccessible for other reasons (e.g., significant travel, medical leave), this, too, should be noted. When relevant, it’s helpful to show the percentage of time staff is typically available to perform the process when the work arrives.
