Value Stream Mapping – Future State What makes a Value Stream Lean? Get each process to make what the next process needs, when it needs it. • Avoid overproduction • Avoid separate, uncoordinated activities • Reduce queueing and waiting Eight ideas follow…
Value Stream Mapping– Future State 1. Produce to your Takt time This synchronizes the flow in the hospital to match the patient demand Takt time = available working time per day patient demand per day
Value Stream Mapping– Future State 2. Develop continuous flow wherever possible This means treating one patient at a time and passing immediately to the next step Isolated islands Continuous Flow Queue Queue Queue Queue Queue Queue
Value Stream Mapping– Future State 3. Use supermarkets to control the process if continuous flow does not exist upstream Supermarket Pull System PRODUCTION KANBAN WITHDRAWAL KANBAN supplying process receiving process A B SUPERMARKET
upstream process downstream process Value Stream Mapping– Future State 3. You can also use a FIFO lane between two processes Kanban STOP FULL Max. 10 patients FIFO Lane SUPERMARKET
Process 1 Process 4 Value Stream Mapping– Future State 4. Try to send the patient schedule to only one process step Selecting the “Pacemaker process” SCHEDULE Process 2 Process 3 pull pull FIFO FLOW SUPERMARKET SUPERMARKET
Process 1 Value Stream Mapping– Future State 5. Distribute the treatment of different patients evenly over time at the pacemaker process This means leveling the patient mix. Schedule OXOX
Value Stream Mapping– Future State 6. Create an “initial pull” by releasing and withdrawing small, consistent increments of work at the pacemaker process This means leveling the production volume Load-leveling box 8.00 8.15 8.30 8.45 9.00 9.15 9.30 A A A A B B B C C C
Value Stream Mapping– Future State 7. Develop the ability to make “every part every day” (then every shift, then every hour) in treatment processes upstream of the pacemaker process
Value Stream Mapping– Future State 8. Develop process improvements to enable the future state design This is the place to note any equipment and procedural improvements These are represented by a Kaizen lightning burst Kaizen
