Why Value Stream Mapping? To set strategy before diving into tactics. Enables us to SEE the process. Promotes systems thinking / seeing the whole  Helps us avoid sub-optimizing © 2010 Karen Martin & Associates 10

Why Value Stream Mapping? (continued) Shows the linkage between information and material flow. Makes the disconnects and obstacles to flow visible at a macro level Metrics-based decision making: What are you going to do to affect the numbers? © 2010 Karen Martin & Associates 12

Key Metrics: Time Process time (PT)    The time it takes to actually perform the work, if one is able to work on it uninterrupted Includes task-specific doing, talking, and thinking aka “touch time,” work time, cycle time Lead time (LT)    The elapsed time from the time work is made available until it’s completed and passed on to the next person or department in the chain aka throughput time, turnaround time, elapsed time Includes Process Time, not merely waiting time. © 2010 Karen Martin & Associates 13

Key Metrics: Quality %Complete and Accurate (%C&A)   The percentage of input that’s deemed “usable as is” by the person doing the work % of incoming work where the downstream customer can perform task without having to “CAC”:  Correct information or material that was supplied  Add information that should have been supplied  Clarify information that should have or could have been clearer   Measured by the immediate downstream customer and all subsequent downstream customers. Similar to first pass yield in manufacturing. © 2010 Karen Martin & Associates 17

Summary Metrics: Quality Rolled First Pass Yield (RFPY)     The percent of value stream output that passes through the process “clean,” with no “hiccups,” no rework required. RFPY = %C&A x %C&A x %C&A… Common finding = 0-15% Multiply ALL %C&A’s, even if parallel processes © 2010 Karen Martin & Associates 18

Summary Metrics: Time Percent Activity (%Act) (also referred to as Activity Ratio)      The percentage of time anything is being done to the work passing through the system (whether value-adding or non-value-adding) %Act = (∑PT ÷ ∑LT) × 100 100 – %Act = % Time Work is Idle Common finding = 1-10% Could also calculate %VA to show much activity is value-adding – is typically lower than % Act. © 2010 Karen Martin & Associates 19

Summary Metrics: Measuring Productivity Gains Labor Effort # FTEs = Total PT (in hrs) X # occurrences/year Available work hrs/year/employee Freed = Current State FTEs – Future State FTEs Capacity Note: Improvement can be expressed as Freed Capacity (FTEs), Time, or Labor Expense (or all) # FTEs = Full Time Equivalents; 2 half-time people = 1 FTE © 2010 Karen Martin & Associates 23

What do you do with freed capacity?  Absorb additional work without increasing staff  Reduce payroll through natural attrition  Innovate – create new revenue streams  Conduct ongoing continuous improvement activities  Do a better job with fewer errors and higher safety  Talk and work with your customers and suppliers  Mentor staff to create career growth opportunities  Provide additional workforce development; cross-train  Better work/life balance  Slow down & think  Get/stay caught up  Do the things you haven’t been able to get to  Collaborate with other areas © 2010 Karen Martin & Associates 24

Value Stream Mapping Activities Team-based Heavily weighted with those who can authorize an innovative future state.  The team goes to the gemba to obtain the metrics from those doing the work. Three day activity; three deliverables. Leadership learning is huge. Interim briefings are a key success factor. © 2010 Karen Martin & Associates 25

Step 2  Identify all blocks in the process (target 5-15 blocks)  Customer icon is placed in upper right or middle  Upper right if supplier exists (supplier is placed in upper left)  Middle position if a separate supplier doesn’t exist        Supplier (if relevant) is placed in upper left Each block (post-it) contains an activity or group of activities that occurs before a break in the timeline occurs (typically WIP or handoff) Activity format is verb/noun – what happens to what Include the function who performs the task Include number of workers who perform the task Include any obstacles to flow – batches, shared/inaccessible resources, system downtime, etc. Consider walking the process © 2010 Karen Martin & Associates 44

Post-it Conventions Process (Verb/Noun) Function # Staff (if relevant) Barriers to flow

Step 3 Identify all I.T. systems used in the process and information flow     For most VSMs, these are placed above the process blocks In very complicated VSMs with two rows of process blocks, I.T. systems can be placed between the rows, if necessary.

Future State Design Goal: Removing all obstacles to flow (“the thing” should never stop)        Batches Rework WIP / Bottlenecks Handoffs Setup / changeover Physical layout Motion & transportation © 2010 Karen Martin & Associates 62

Eight Questions for Future State VSM 1. What are the customer requirements? What’s the takt time? 2. With goods, will we produce to order or to finished goods inventory? (With services, you’re almost always producing to order.) 3. Where can continuous flow be put in place? 4. Where should pull systems be implemented? 5. What is the single point of scheduling? 6. How do we level the load and the mix? 7. What should the management time frame be? 8. What process improvements are necessary to achieve the future state? -- Rother & Shook, Learning to See © 2010 Karen Martin & Associates

Future State Design Considerations  Eliminate steps / handoffs  Combine steps  Create parallel paths  Alter task sequencing and/or timing  Implement pull  Reduce / eliminate batches  Improve quality  Create an organized, visual workplace  Reduce changeover  Eliminate motion & transportation  Standardize work  Eliminate unnecessary approvals / authorizations  Stop performing nonvalue adding (NVA) tasks  Co-locate functions based on flow; create cells (teams of crossfunctional staff)  Balance work to meet takt time requirements 64

The Right Process Standardize work Mistake proof work Make problems visual Fix problems immediately Create continuous flow Level demand Balance work Create pull systems © 2010 Karen Martin & Associates 65

Common VSM Facilitation Issues Keeping the team focused on the macro view (rooftop level); it’s tempting to go into the weeds Keeping the team focused on the current state Assuring the team and leadership that directionally correct data is good enough Time management  Schedule Gemba time and conference room time very tightly Getting the right people on the team Getting the right people at the interim briefings © 2010 Karen Martin & Associates

Common Differences - Manufacturing vs. Office VSMs Manufacturing Office Upper right Center Upper left None “The thing” we’re following Raw material, subassemblies, finished goods Paper, verbal, and electronic Information Information Flow More structured / formalized I.T. systems Multiple I.T. systems and work-arounds Multiple points across VSM Work not scheduled Yes Sometimes Inventory triangle In-bin (if preferred) First Pass Yield (FPY) Percent Complete & Accurate (%C&A) Takt Time Typically can be applied Only applicable with dedicated resources LT determination for each block Based on WIP between process blocks Based on a single item passing through Customer icon Supplier icon Schedule notification Material flow (via hollow arrow) WIP icon Quality Metric
