Industry has traditionally used Labour Efficiency to
set targets for Numbers produced per day andmeasure performance.

Manufacturing Losses
• For machine based processes this efficiency
measure is inappropriate:
Emphasis is focused on Labour
The target becomes a quota; either easy, too hard or
occasionally just right
Machines breakdown or run at a particular speed
regardless of how many people are in attendance or
how hard they work
Machine downtime is lost once labour is redeployed
Overall EquipmentEffectiveness (OEE)A Better Metric

• Developed By The Japanese Institute of Plant
Maintenance (JIPM) in 1971,to overcome
“Manufacturing Chaos” such as:
Plant Availability
Plant Performance (which includes people’s
performance if relevant)
Quality Levels
Overall Equipment Effectiveness (OEE)
6
SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
What’s OEE for:
• Performance measurement
• Identifying and understanding losses
• To make us think about how to reduce losses
and ultimately eliminate losses
• Who?
• Production
• Engineering
• QA, Engineering, etc

Who uses OEE?
• All the “Big Players” such as “Ford” use OEE as a
performance indicator, and it is generally
accepted that:
An OEE of 85% is a “World Class” Performance
• Companies working out their OEEs for the first
time are taken aback by 20-30% performance

SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
How does OEE drive improvement?
• Local Metric – its for the shop floor and productionsupervision to measure performance and look forimprovement opportunities
Keep Graph Overall and 3 contributors at Gemba – supportwith Cause and Effect Diagrams & Action lists. Part of aVisual Management System
Does the workforce get the most from the plant? Is a fairquestion
• Production Engineering often “own” the plant. What’s thebottle neck process? Can it be speeded up? Why does theplant produce defects? Why do minor stoppages occur?Often a big contributor - count them
10
SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
How does OEE drive improvement?
• Maintenance – Spares holding and positioning.Fitter availability. Preventative maintenance.Change over time reduction (not frequencyreduction)
• SMED for change over:
External Activities get ready: materials, tools, parts,information
Internal – Speed up – quick release couplings etc
Write SOPs so people know what they are doing

SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
But
• Don’t forget schedule attainment – high OEE
making something a customer doesn’t want is
waste
• OEE plant wide is an average nonsense. Target
critical machines – Bottle necks then Pareto
• Don’t make OEE an end in itself, be sensible with
cost of improvements ie large cost vs small gainwould be counterproductive waste

What target? Best of best
• The “Best of the Best” indicate what ispossible & the question asked is:
Why this OEE performance is not achieved all
the time?
The Best of Best can be a short term target but
if OEE is low we’ll need to get beyond this
Often - in the short term there is no target.OEE is a diagnostic Tool - we’ll see what weget - understand root causes and set targetsfor improvement

Machine Run Rate
• Determine the “Machine Run Rate”………..
• Time the number of items produced by the machine in a minute…………...
• The plant has been timed at producing 8 off items per minute,therefore…………
Machine Run Rate = 1 minute / 8
Machine Run Rate = 0.125 minutes
• Remember: Full Speed – no allowances
24
SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
Performance
• Suppose in the day we produced 1200 items
• % Performance = Machine Run rate x Processed Amount x 100
Operating Time
ie .125 mins / Unit x 1200 Units x 100
435-60 mins
% Performance = 56.25%

• Why did the breakdown occur?
• Why did it take an hour to fix?
Did the fitter turn up quickly? Did he have the part needed forrepair to hand?
• Did the crew take a break when the machine was down(rather than at the “appointed time” when it was back upagain)?
• What can be done to reduce a 5% scrap rate?

• USE OEE to identify & correct Manufacturing
• “Weaknesses”

So let’s work another one through…
• Your shift runs 06:00 to 14:00
• You have 1 x15 minute break and 1 x 30 minute break during the shift
• During the shift you had two plant failures of 30 minutes and 45 minutesrespectively which stopped production. A Spare had to be fetched for thesecond repair
• You produced 2000 items
• The machine speed is 10 items per minute
• 10 of these were reject, and had to be scrapped (rework would count too -not right first time)
• Please calculate the availability, performance, quality efficiency, and theoverall OEE

Golden Rule
• Cells will be encouraged to ask “What if”………….
• What if we did not have to wait for an Fitter?
• What if we did not have to wait for a spare part?
• What if we had a breakdown mid morning break and took
our break then rather than waiting for the right time?
• What if the plant is running and we took a break by splitting
the shift?
• What if we developed a Capital Case to replace the plant?
40
SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
Let’s try to answer some of thesequestions• Let’s remove the some of the Unplanned
Downtime (waiting for Fitter 15 mins & waiting for
spare to be fetched 15 mins, total = 30 mins)
• Downtime is reduced to from 75 to 45 mins………
• And if we assume an extra 120 items could be
produced increasing our output from 2000 to
2120……………..

Outcome
• We can see an improvement of 7% on Machine
Availability and an increase of 2.8% on OEE
• These are small theoretical increases, but they
cannot be discounted……………………………….
• Many small gains all add up
44
SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
More what ifs
• The obvious questions arise……………………….
• Why can’t we have more fitters?
• Why not keep a spare part on the job?
• Can we take breaks nearer the job?
• Can we have a extra hand at break times to make
splitting easier?

What about a new machine?
• We can see an improvement of 17% on Machine
Availability and an increase of 18% on OEE
• We would break manufacturing records:
Allow delivery to customer to promise
make better use of Labour
watching a broken machine has to be unfulfilling as well as a
waste
• There would be a payback for the capital investment
• First we need some data show how bad things are
50
SSG06101ENUK – Delegate Slides/Issue 1.1/ April 2008
OEE is:
• A tool for Cells to record and then identify wheretheir Manufacturing weaknesses are, and torectify these by CI Meetings, seeking assistancefrom Engineering, QA and Finance or other
departments where necessary.
