Creating Visual Management SystemsWhat is Visual Management?
There are two categories within Visual Management:
Visual Control – manage inputs to the process
Visual control should highlight normal / abnormal conditions and promote a response
• Is the equipment running correctly • What product/batch is being made?• Long cycle time – what stage is production at?• Are conditions normal/abnormal?• When does material need to be reordered?• Do we need to manufacture?• What are the corrective actions?
Examples of Visual Control Oil gauge Heater control 5S set in order locations
Visual Display – displays in a clear manner the outputs or performance of a process
must be relevant to the area or improvement must be displayed close to the improvement area Information must be kept up to date by the owners of
the process i.e. operators on the machine Abnormal results must be acted upon to drive
improvement Must be easy to understand
Examples of visual display• Health & Safety• RFT• Costs• Delivery• Responsiveness• Concerns & corrective actions• Workplace organisation
Where to find the information for visual display • Batch sheets• Manufacturing plans• Quality systems• Audits• Management reports
When selecting an area for implementing a Visual Management system you must consider

Creating Visual Management Systems
- What is it that you want to improve - Implement controls to improve the operation of the
area - Only display measures of what you want to improve
Visual Management Systems (Visual Factory)
Visual Techniques are often used to ‘automatically’ manage the workplace, techniques that can be used are;
Kanban systems – control stock levels. Components, spares, WIP can only be placed into the Kanban location if there is a space in which to put it. If the Kanban space is full in the case of WIP, then the upstream process will stop producing until the WIP is taken by the next process.
Floor Footprints –a place for everything, everything in its place. Often used in conjunction with Kanbans but also 5S to ensure equipment is available when you need it.
Card Systems – visually display current status. E.g. maintenance schedules show when servicing. Operators can also add cards as repairs are required. Card systems can also be used for scheduling manufacturing.
Colour Coding – can be used to show where equipment should be placed, what it should be used for.
Team Boards / Visual Display Boards – can be used to show graphs of performance, instructions, notices etc.
Key Performance Measures / Indicators (KPIs)
• Identify relevant measures – what do you want to improve?
• Display graphically• Make specific to machines, equipment or area (use
local measures that are related to business measures)• Updated by operators not management• Keep information current
KPIs can be split into two categories
Business Performance Measures- Show the big picture, how is the business performing
against the business objectivesExamples
- Stock Turns- Floor Space Utilisation- People productivity- Not right first time- On time and in full- Schedule Adherence- Yield- Health and Safety-
Local Performance Measures- Sow how the local area is performing against its

- OEE- Yield- Cycle time improvement- Changeover time
Measures for lean
HS&E
Chart, No of man day lost for reportable accidents
Right First Time
Total production output - Quantity of Product scrapped or needing extra work x 100 Total Production Output
CostMany measures will indicate performance on cost, for example OEE, if OEE is increasing then cost will be decreasing.
Product Cost Down shows the percentage reduction in cost year on year or in a given period
Last year or previous cost - This years or current cost Last years or previous cost
Delivery
Delivery schedule achievement is measure of how well you are matching the planned delivery schedule of the customer
No of Planned Deliveries – No of Incorrect Deliveries x 100 No of Planned Deliveries
Responsiveness
Can be measured using lead time, divide 1 by the number of stock turns to get how many times you turn stock around per year. I.e. a stock turn of 12 means stock is turned around every month – lead time is 1 month
Stock Turns is ratio of how much stock is held and the annual sales turnover, giving the frequency of stock turnover
Sales Turnover…………………….. Value of Raw Materials, WIP and Finished goods on site
Process Concerns and Corrective Actions
Notes
Page 8 of 12 Revision 1.1
Creating Visual Management Systems
Can be measured by trending the number of concerns or corrective actions. To measure an improvement the following equation can be used
Last years or previous concerns - This years or current concerns x 100 Last years or previous concerns
Performance Measures
OEEAvailability – The percentage of the total available time that the equipment is running
Total Available Time – Total Downtime x 100 Total Available Time
Performance – The percentage of the maximum possible production rate that the equipment averages when running
Ideal Cycle Time x 100 or Average Production Rate x 100Actual Cycle Time Max Production Rate
(where ideal cycle time is shortest possible or best demonstrated time and Max production rate is highest possible rate)
Quality – The percentage of product made that is of a quality acceptable to the customer
Total Product in Specification x 100 Total Production Output
Sometimes yield instead of or in conjunction with quality – The percentage of the maximum possible yield that is obtained on average from the process
Average Yield x 100 Ideal Yield
Where Ideal Yield Max Possible Quantity of Finished Product x 100 Quantity of Raw Materials Consumed
Average Yield Average Quantity of Finished Product x 100 Quantity of Raw Materials Consumed
OEE Availability x Performance x Quality x Yield x 100e.g. 0.8 x 0.85 x 0.95 x 100 = 64.6%
Workplace Organisation
Using scores from audits to produce a spider chart or similar to graph performance

Creating Visual Management SystemsVisual management and Improvement activities
Many improvement activities will drive visual management systems for example
Stock reduction or stock management improvement uses Kanban systems. Kanban means signal, for example a signal to replenish stock because the stock location has reached minimum quantity would be sent to a manufacturing cell to start production.
Visual Boards such as card systems can be used to provide level scheduling.
How is the Deming Cycle Applied?
Control Display
Follow the PDCA cycle to improve, use the outputs of the process and drive improvements to the control of the inputs of the process
PLAN - What is the current situation?-Where do we want to be?-How are we going to get there?
DO -Trials, improvements, changes – test the planCHECK -Where are we now?
-Did we achieve the plan? Why not?ACT - Make improvements permanent, act upon the results,
trial new methods

Creating Visual Management SystemsMeasurement Techniques
Target v ActualShows a trend of the measure, examples of use, output trending, No of quality issues
Percentage Right First time / Pie ChartShows percentage defects/loss from total
Bar ChartCan be used to show reasons for rejects, lost time etc.
