## Car Parking & Six-Sigma

Amrendra Roy

We can easily understand the concept of six-sigma using the analogy of parking a car into the garage and if you want to understand it more seriously, just imagine that you are entering a tunnel (instead of garage) at the speed of 150-200 Km/Hr!

When ever a car is bigger than the garage, it’s not possible to enter the garage. Take another car whose width is slightly less than the width of the car. This time it is possible to enter the garage but we will get frequent scratches unless you are an expert driver! Take a third car whose width is just half of the width of the garage , it’s is now possible for me to enter the garage even if I am drunk.

Car width represents the “current process capability

Garage width represents the “Customer’s specifications

We should remember that

“We need to buy a car according to the dimensions of the garage”

“We need to change our manufacturing processes to meet the customer’s specification”

What’s the big deal, let’s rebuild the garage to fit the bigger car!

How the garage/car example and the six-sigma (6σ) process are related?

What do we mean by garage’s width = 12σ and car’s width = 6σ?

Now Let’s start talking about 6sigma

Is this information useful to you?
