Kaizen is a Gentlemen’s Sport – Time Studies Hit Below The Belt

Time studies are inhuman

Why do a Time Study when you can Kaizen with the Team

I don’t think any one likes to be timed or watched.

I wonder whether real Black Belts ever ask for time studies

Then how do you do the measure in DMAIC?

I call it self measurement

Without trust there can be no progress

Revisiting Pareto Charts – Process Improvement & Low Hanging Fruit – Instant Gratification

http://asq.org/learn-about-quality/cause-analysis-tools/overview/pareto.html

ASQ is a great place to browse and learn. The link above is a concise write up of the power of a Pareto Chart and how the same can be generated in Excel. You could do it with Minitab as well.

My first brush with a Pareto chart was in 2001

My assignment for the week was to increase the yield of a packaging line with a major manufacturer of diabetes bio-sensors.

I walked the line, talked to the operators and talked to one of the engineers

Here is the low down

  • The operators maintained a very clear record of the down time and frequency
  • The data was collected and stored in a database
Went and met the keeper of the database
He was thrilled and mentioned that he was waiting for the day when some one would come in and ask him for the data.
Got the data plugged it into Excel and created a Pareto Chart.
Passed it around the weekly meeting with a smug look
Here are the top hitters
  • Meetings
  • Repairs to literature folder
Action
  • Have communication on the line and reduce wasteful meetings
  • Bring in the literature folder company rep and recondition the system
ROI or is it Return On No Investment?
  • Increase in yield from 75% to 95%
Is that instant gratification or what?
Well since then I have used the Pareto Chart any number of times with success and little effort
Who needs training courses?
Is that LEAN manufacturing or what?

NASA’s Puffin: The Personal Electric Air Vehicle – The New Age Personal Emotional Mobile – Go PuffinPOD

NASA’s Puffin: The Personal Electric Air Vehicle.

One step closer to a personal electric vehicle you can take anywhere.

  • Maybe a city without roads with your Puffin taking off from the terrace
  • Maybe even with an Automatic pilot so that you can be on your iPad as you travel
  • Your local sheriff would own one
  • So would your vermin exterminator
  • Who knows, in India sabji wallahs may hover over your windows in a high rise selling vegetables
  • The puffin may spawn new designs in architecture
  • Your personal grand canyon adventure on a Puffin.
  • Your mail man, Fedex man and friendly UPS man may start using it too
  • Dream on

The Last Straw That Broke The Camel’s Back – A Lesson In Root Cause Analysis

Root Cause Analysis is looking at the causal effects for a failure and install controls to prevent repetition of the problem. Usually there will be multiple causes which combine to create the failure.

Let us contemplate what was the cause for the camel’s back to break

  • True it is overloading beyond the capability of the camel. But how do you specify the load a camel will carry. It is dependent on the camel’s health, temperature of the day, the terrain, speed of travel and the skill of the camel jockey.
  • The health of a camel depends on the nutrition and care bestowed by the jockey and his skill in choosing the right time to travel as well as scout out the most comfortable terrain to navigate.
  • Designed experiments help set up the parameters which will help the camel carry a set load under given conditions.

Here is an excellent link on the subject

Vibration Feature Pattern Matching – Machinery Prognostics Tool – LabView

LabView can help us predict machine failures before they occur.

A very informative link is to visit ni.com/info and enter nsi1105

What is Vibration Feature Pattern Matching?

A very good explanation is found at

http://zone.ni.com/devzone/cda/tut/p/id/9230

Quoting from the link

“By capturing dynamic measurements from operating machines such as vibration, electrical power, and dynamic pressure; it is possible to extract key component signature features.  With this feature information, it is possible to tabulate specific metrics which drive plant maintenance and production schedules”

Here is an excellent link from Penn State on Machinery prognostics and Condition Monitoring
