Using the Basic Kaizen Tools
3 1 2 Pair up 2 for each process. One times w/ stopwatch, other jots down times. Find best times. Verify if Cycle Time meets Takt Time. Calculate Takt Time. Identify problems. Set targets and enter on Target Progress Report Plan & initiate Kaizen Workshop. Observe site. Identify Process. Prepare Standardized Work Sheet 4 5 6 If equipment seems to lack in capacity, use Capacity Sheet to define problems. Fill out Standardized Work Combination Sheet with best times. Note long times on Combination Sheet, there are opportunities for Kaizen. Continue to observe site, note problems on Kaizen Newspaper Try out ideas for kaizen immediately, verify results. Prepare Kaizen Proposal Sheets for effective kaizen ideas. There is no set order to using the basic kaizen tools, but there is a normal pattern. 7 Update Kaizen newspaper. Update Target Progress Report. Kaizen EVERY DAY!!.

INVENTORY WALKING DISTANCE MATERIAL TRAVEL DISTANCE LEAD TIME (sec.) CYCLE TIME (sec.) OUTPUT (units / day) CREW SIZE PRODUCTIVITY Quantify current state and target state. Add relevant categories when necessary. Write improvements (lowered inventory, shorter walking distance, etc.) in RED INK. Use the target progress report to report on status of activities at the end of each day and at the presentation at the end of the week-long workshop. CHANGEOVER TIME (sec.) REMARKS:

STANDARDIZED WORK SHEET
DATE: _____/____/____ Approvals: Process: __________________________ Part # ____________________________ Part Name: ________________________ Scope of Operation FROM: TO: Use grid to express site to scale accurately and remember to include “real world” aspects such as posts, trash cans, tool boxes, break areas -- whatever is truly in the area. Do not forget to fill out the “BASIC DATA,” without it Standardized Work cannot be defined. Try to break up the process into the shortest steps possible. Each step of the operation sequence must be shown where it is done and given a sequence number. These numbers are identical to those entered in the Standardized Work Combination Sheet in the “Step” column. Connect the sequence numbers with solid lines that truly express the route traveled by the operator. Do not use arrows. The sequence numbers express the direction of movement. Do not forget to express the path the operator takes to return to the first step with a dotted line. SYMBOLS NOTE: Takt Time, Work Sequence (same as numbers in “Step” column on Combination Sheet), and numbers of Standard Work in Process must be known to define Standardized Work. Identify all safety concerns, points where quality must be verified (go/no-go) and numbers of pieces of standard work in process using the symbols to the right.

TIME OBSERVATION SHEET
Page _____ of _____ Date / Time: ___/____/____/_________________:________ Observed by: _____________________________________ Line / Process: __________________________________________________ # Step 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Best Time Observations (changeover time) 1 2 3 4 5 6 7 8 9 10 11 Time many cycles to increase accuracy. “Step” column entries are identical to sequence numbers on Standardized Work Sheet and Standardized Work Combination Sheet. Partner with another person - one runs stopwatch and calls times for each step while observing the process, the other writes down times on sheet. Keep stopwatch running, write times called for steps above dotted line. After observation has been completed, subtract to calculate splits for each step and write below dotted line. Calculate complete times for each cycle observed and enter at bottom of column. Find best time for each step and enter in “Best Time” column. Total best times and enter in bottom row (“Complete Cycle Time”). ALWAYS USE THE BEST TIMES FOR CALCULATING CYCLE TIME. DO NOT AVERAGE TIMES. 12 13 14 15 Complete Cycle Time

Cycle Time / Takt Time Bar Chart (Blank Chart)
Process Cycle Time / Takt Time Bar Chart Cycle Time / Takt Time Bar Chart (Blank Chart) Print out a hard copy for use in your workshop. Denote takt time with a horizontal red line across the length of the chart. Denote the length of the cycle time for each process with a vertical bar over the corresponding process number. Cycle times that are longer than takt time are candidates for kaizen or re-balancing of tasks.
7
Cycle Time / Takt Time Bar Chart (with Graphing Feature)
Double-click on the graph and use the graph editor to enter the cycle times for each process in the spreadsheet provided. Quit the graph editor and the bar chart will be generated automatically. Place the red line at the appropriate height in on the chart to denote takt time. Click after the red “T/T” to enter the takt time value. Cycle times that are longer than takt time are candidates for kaizen or re-balancing of tasks. While it is better to hand write the Kaizen tools during activities (for speed and flexibility) this slide is handy for presentations and recording final results.

Yamazumi (Stack) Chart (Blank Chart)
Cycle Time Process Yamazumi (Stack) Chart Yamazumi (Stack) Chart (Blank Chart) Print out a hard copy for use in your workshop. Denote takt time with a horizontal red line across the length of the chart. Denote the length of the cycle time for each element of each process with a vertical stack chart over the corresponding process number. The Yamazumi chart aids in targeting tasks for kaizen in a process that does not meet takt time, and as a last resort for re-balancing (re-assigning) tasks to meet takt time.

Yamazumi (Stack) Chart (with Graphing Feature)
T/T Double-click on the graph and use the graph editor to enter the cycle times for each task of process in the spreadsheet provided. Add more tasks as needed. The graph editor will automatically chose colors and calculate. Quit the graph editor and the bar chart will be generated automatically. Place the red line at the appropriate height in on the chart to denote takt time. Click after the red “T/T” to enter the takt time value. The Yamazumi chart aids in targeting tasks for kaizen in a process that does not meet takt time, and as a last resort for re-balancing (re-assigning) tasks to meet takt time.

STANDARDIZED WORK COMBINATION SHEET
Operator _____ of _____ Line: ____________________________ STANDARDIZED WORK COMBINATION SHEET Date: ______/______/_______ Quota / Shift: ____________ MANUAL: AUTO: WALKING: Process: _________________________ Section: __________________ Takt Time: ______________ sec. Step Description Time TIME (unit: 1 sec.) Man Auto Walk 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 1 BE CERTAIN TO SHOW TAKT TIME by drawing a straight, vertical line in RED INK at the appropriate point along the time line. Try to break up the process into the shortest steps possible. End each line with a short vertical line. Don’t forget to connect the end of one step with a the next step using the wavy line when there is walking between steps. Don’t forget to connect the end of the final step with the beginning of the next cycle, this time going up to the first row, when there is walking to return to begin the cycle again. If automatic run times (dotted line) run past takt time, finish them by drawing the remainder of the line from the 0 line. Any long lines are likely to be opportunities for kaizen. Totals Waiting

KAIZEN PROPOSAL SHEET Location Objective Date Operator Before After Use pictures (sketches, photos, cartoons, etc.) in “Before and “After” boxes. Express proposal visually as much as possible and avoid verbal descriptions. Quantify “Problem” and “Effects” whenever possible. Examples: “Cycle time is 4 seconds over takt time.” “Standard Work in Process: 3 pcs., should be 1 pc.” “Searching for adhesive: 5 secs.” “5 instances of wrong bolt/hr. observed.” Problem Effects (cycle time / inventory / changeover time reduction,poka yoke etc.)

Post in the area and check for completion deadlines at meeting at beginning of every shift. Add kaizen proposals as they are offered. The Kaizen Newspaper should change every day.
