Lean Techs Advent Calendar

julekalender 2017

Sissel Lundeby presents Lean Techs advent calendar. You can watch a new video every day from 1st to 24th of December on Youtube or LinkedIn.  

Altogether 24 Christmas balls; one every day goes through the Christmas process and the result is registered. Statistical process control - SPC, is used to determine the normal variation of the process. Will the Christmas process satisfy Santa's specifications?

We will see on Christmas eve! Watch the calendar at Youtube or LinkedIn (the videos are in norwegian but you can choose english text). Guess the result of the following day by commenting on the videoes at Linkedin!  You can win statistical process control training.

Do you overreact?

processcontrol

 

When do you respond to a test result? Do you use facts or intuition? Do your customers decide when to react?

Or maybe you use statistical process control?

How do you react? Do you start looking for a special cause? Or maybe you review the entire process and consider factors that may influence?

It is easy to overreact to normal variation. There will always be variation present.

Are your processes capable?

robust process

I have experienced operators adjusting a machine in despair because the machine produced rejects. No matter how much they adjusted, the machine still produced rejects.

The adjustments did not help, in fact it resulted in more rejects. What was causing the rejects?

The machine was not robust enough to deliver the desired result.

How about your processes? Are they robust?

Quality every time


quality improvement

I do not intend to start a discussion about which came first, the chicken or the egg. I leave that to others :-)

However, this post is about boiling eggs, and how to always achieve the same quality of a process.

I had a summer job at “Sjømennenes Helsehjem” many years ago, and how to boil the eggs was a hot topic. The customers / residents were not always pleased with the boiled eggs. However, it was complicated to please them since some residents were very happy while others were dissatisfied, with eggs cooked exactly the same way.

They had different preference for quality.

Which sense react fastest? Vision or hearing?

statistical process control

What do you think?

The best way to find out is to test! It is possible to test it at the Norwegian museum of Science and Technology.

I did an experimental design where I tested age, gender and sense (vision and hearing). My brother in law (35 years), my son (10 years), my niece (7 years) and I (41 years) were volunteers. We took the time we spent on registering sound and light.

My brother in law was a tiny bit faster than me when reacting to sound, followed closely by my son and my niece. For light my brother in law was fastest, then my son, followed by me and my niece. What does this result mean?

Process control

Achieve Process Control by using SPC!

statistical process controlProcess control is about understanding your process, only then can you control it. To understand the process, you must understand variation.

Six Sigma use SPC (Statistical Process Control) to control processes. SPC is a tool to distinguish between normal and special caused variation.

Why should you distinguish between normal and special cause variation? Because special and normal cause variation requires different approach when identifying causes of variation.

Quality improvement

"The devil is in the detail"

quality-improvementYou achieve quality when you control the important details. When improving quality it is important to consider all the details. However, some details are more important than others. If you can select the details that matter the most and focus on them you will achieve quality. This applies to athletes, manufacturing companies and everyone else. I work mostly with manufacturing companies and use tools within Six Sigma to improve quality. Six Sigma has much in common with Lean, meaning customer focus, process understanding and focus on measurements rather than intuition. A challenge when it comes to quality improvement can be to identify the critical factors and then to control them.
