    Over time, the parts                         what is good for the whole,
     develop measures that they                   NOT what is good for the

The TOC Process of Continuous
                           Improvement
           1. IDENTIFY the systems Constraint(s)
           2. Decide how to EXPLOIT (Maximise) the systems
                        constraints
           3. SUBORDINATE (Align) everything else to the
              above decisions
           4. ELEVATE the systems constraint(s)
           5. If the constraint was broken, go back to step 1.
              Do not allow INERTIA to become the systems
              constraint

PURPOSE of Ops Room
       THE WHAT:
        The Primary reason for the existence of the Ops Room is to
         facilitate the optimization of the process flow through
         identified bottlenecks in the system
       THE HOW:
        This is achieved within a system that fully supports the flow
         and it is done through the desired behaviour of people
        It has to take place in a culture of openness and good
         visibility
       THE OUTCOME:
        The outcome of the ops room process is to have significant
         increase in the operational output of the system as a whole
         and to create an environment for consistency and the
         sustainability of that output

Operating Rules for a TOC Chain
        Run the constraint with military precision (on the
         clock, exactly)
        The buffers are there to protect the constraint
         from variations in the system  they must be
         adequate at all times Whenever the flow stops, it
         means the buffer ran out.
        Everybody must support and align with the needs
         of the constraints
        Without brutal honesty and clear visibility we will
         always be busy chasing our own tails
        Whenever the protective capacity of any
         subordinated resources falter, make it known!

Evaluating a TOC Implementation
         Where is your bottleneck or core problem ?
         Availability and utilisation levels of the bottleneck? Close to 90%?
         The schedule of the constraint and how well it adheres to the
          schedule (military precision) ?
         Impact of starvation and blockage on the constraint less than
          10%?
         Fluctuation of the buffers that protect the constraint ?
         Rules of subordination and how well are they adhered to,
          especially by service departments ?
         War room and explain how the win-win rules work in practice ?
         Supervisory levels understand their roles in meeting the demands
          of the constraint(s)?

  • 11. PURPOSE of Ops Room THE WHAT: The Primary reason for the existence of the Ops Room is to facilitate the optimization of the process flow through identified bottlenecks in the system THE HOW: This is achieved within a system that fully supports the flow and it is done through the desired behaviour of people It has to take place in a culture of openness and good visibility THE OUTCOME: The outcome of the ops room process is to have significant increase in the operational output of the system as a whole and to create an environment for consistency and the sustainability of that output Heuristic FLOW 11 Goldratt Group (Southern Africa) 息 2004 Heuristic Flow 息 2008
