What is PPM?
(Parts per million)
Parti per Milione (PPM) e Cialis sono entrambi farmaci usati per trattare la disfunzione erettile,maggiori informazioni su Cialis qui. PPM è un farmaco a base di sildenafil, un inibitore della fosfodiesterasi di tipo 5 (PDE5). È usato per aumentare la circolazione del sangue al pene e aiutare gli uomini a ottenere e mantenere un'erezione. Cialis è un farmaco a base di tadalafil, un altro inibitore della PDE5. È usato per aumentare la circolazione del sangue al pene e aiutare gli uomini a ottenere e mantenere un'erezione. Entrambi i farmaci sono disponibili sotto forma di compresse da assumere per via orale. Entrambi possono essere assunti con o senza cibo. Entrambi i farmaci possono aiutare gli uomini a ottenere e mantenere un'erezione, ma Cialis può anche aiutare a prolungare l'erezione. Entrambi i farmaci possono a
PPM (Parts per million) is a measurement used today by many customers to measure quality performance.
Definition: One PPM means one (defect or event) in a million or 1/1,000,000
There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM. Now the rate for most automotive components is targeted at 25 PPM or 0.0025%
To calculate: For example, let's say you had 25 pieces defective in a shipment of 1,000 pieces. 25/1000= .025 or 2.5% defective. .025 X 1,000,000 = 25,000 PPM.
Let's put it in perspective. Let's
say, you produce 10,000,000 parts per year for your customer. If you're
like most companies, your plant operates around 5 days a week, 50 weeks
per year or 250 days a year. Let's assume your customers requirements
are 25 PPM. That means that you would be allowed 25 pieces for every
1,000,000 pieces or 250 defective parts per year. Or to put it another
way, one bad part per day! Notice I did not say one bad part per day per
person or job, or shift or machine. One bad part for the entire plant
for 24 hours!
Impossible? Yes if you are still using the same manufacturing methods which were responsible for the 5 or 10% scrap you used to accept.
A friend of mine had the following quotation on his wall:
Insanity is doing things the same way we've always done them and expecting different results.
The monitoring and measurement systems we have today have paved the way for improved quality. We can now control the process in order to control the quality. Quality can not be inspected in after the fact. It is the result of careful planning, design, and execution.
If you don't measure it you can not control it.
If you would like to learn how to reduce your PPM while increasing profits I can help.
First by demonstrating a systematic and scientific approach to design and manufacturing in your facility.
Second, by training your personnel in the use of the tools and methodology.
