Are you focused enough on quality?
If you aren’t you should be! Why?
If you don’t pay attention to the overall quality
process nobody else will.
Who gets the blame when things go wrong?
What else?
What Defines Quality from a CAD Standpoint?
Lets discuss – shout out your ideas.
The things I hear from CAD managers …
Standards
Blocks/families/parts
Dimensions/text/details
File formats
Tools (Revit/Inventor/AutoCAD)
Filing procedures
Note the technicality …
What I wish I heard more from CAD managers …
Smooth project execution
Lowered costs
Happy staffers
Happy customers
Happy management
Note the project flow …
Standards are huge part of achieving quality but
until they are part of a working process standards
won’t do much for you.
It All Sounds so Simple
So why is it so hard?
What Impedes Quality from a CAD Standpoint?
Lets share a few observations.
The things I hear from project managers …
Just get it done!
Can’t you hurry up?
We’ll have to cut corners (just once)
We need to make-up lost time
Forget the standards we’ve got work to do …
What I don’t hear from project managers …
It is fine if you screw up
The customer won’t mind mistakes
I won’t get mad when rework happens
Just keep charging hours
Sound familiar …
You’ll always be pushed to cut corners but you’ll
always be blamed when things go wrong. Using
quality control systems is the only way to
eliminate these two nagging issues.
What Tools Can We Use to Achieve Quality?
Here’s what I’ve observed.
They give us a spitball straw …
We need phasers!
These are the spitballs …
Written standards
Blocks/families/parts/annotation
Revit/Inventor/AutoCAD
Filing procedures
Uninvolved management …
These are the phasers …
Error/deviation tracking
Deming process theory
Kaizen methodologies
The Andon chord
Buy-in from management …
You can’t win the quality battle fighting with the
wrong tools – or just CAD tools. Achieving
quality results requires quality based tools.
What does rework cost your company?
David Heinemeier Hansson | Jason Fried
The costs are staggering …
Reformatting drawings
Missed interferences
Inefficient interdepartmental handoffs
Not meeting client requirements
What else …
Add it all up as best you can …
Man Hours x Hourly Rate = Costs
Track costs over time
Time is, indeed, money
Better quality = Lower cost …
If you want management to give you the power to
implement quality control and standards
measures show them what it costs to not do so!
Achieving process Control
Deming Theory
Deming’s theory:
“If you can’t describe what
you’re doing as a process then
you don’t know what you’re
doing.”
The Deming Cycle: Constant Improvement
Basic Deming in action …
Know what people do
Check that they do it right
Act when they deviate
Plan corrective action
Repeat …
“You can have it fast or you can have it good.”
What would Deming say about this?
“Cheap or good or fast – take your pick.”
CAD quality control makes this false!
CAD quality control enables …
Streamlined timelines
Lower error rates
Better quality
Good process gives you: Better products
Faster
At lower costs
Will management like this …
Very few things yield as much potential for
improvement as quality controlled CAD.
Are you preaching this to your boss?
Stopping deviations as they happen
The Andon Chord
Key Andon principles …
When errors happen production stops
Source/cause is indentified
Results are public but not personal
Project management is involved
Fix is made immediately …
Key Andon take-aways …
Production employees are empowered
Management is in on the solution
Error makers are located promptly
Ignoring procedures stops production
The true cost of errors is seen …
Andon is Deming’s Check-Act
Andon sends a clear signal that nobody can “bury
errors” or “ignore procedures” because anyone
who finds the problem can stop the project.
Is your company ready for an Andon chord?
Who, What, Where, When, Why, How
The Kaizen Method
Kaizen + Deming
Kaizen defined …
Key Kaizen principles …
Errors are subject to laser beam scrutiny
The process is on display to all
Solutions are clearly defined
Solutions/problems acknowledged
Accountability is key …
Key Kaizen take-aways …
Errors are attacked
Costs are known and displayed
Everyone is accountable
“Change for Good” improves quality …
Kaizen is Deming’s Do-Check
Kaizen brings all users, managers and
departments to the table to resolve problems in
processes. Everybody is “in the same boat” with
Kaizen and can no longer use departmental
barriers to hide or justify poor quality.
Buy-In from Management
The Secret Sauce of Quality
Key Buy-In principles …
Stress constant improvement
Stress happier staff
Demonstrate process control
Show your understanding of methods
Don’t make it personal – it’s all business
Make cost savings paramount …
Buy-in is all about Deming’s “Act” …
Buy-in is all about Deming’s “Act” …
Without power to act you can’t: Plan, Do or Check
Implement Andon
Implement Kaizen
When management buys-in to quality
they empower you to act …
If your management team doesn’t “buy-in” to
quality control for CAD/BIM processes then your
number one task is to achieve buy-in. Once buy-
in is achieved your number one task is to keep
pushing for improvement.
We’re Done!
I hope everyone is inspired to tackle quality
management when you get back to the office.
