Ranjan replied to the topic VSM – Production Rate Question in the forum General 13 years, 5 months ago
Dear Andy,
the production rate is different from customer demand….. since customer demand is calculated through Takt Time while actual production rate acheived is the cycle time.
Now, in ur case as the present system is not meeting the customer demand (Takt Time), it does’nt mean there will be no inventories. the Production rate in this case…[Read more] -

Ranjan replied to the topic Which Test / Null Hypothesis to Use in the forum General 15 years, 8 months ago
Darth,
I have to still conduct the tensile tests but I believe that the results will be that there is no significant difference on variation of temperature (177 v/s 166 ) or Time ( 2 hrs v/s 1 hour & 15 min)
Considering this if I use these Null hypotheses say
ONE
Ho: average of tensile at 177 for 2 hours = average of tensi…[Read more] -

Hey Elbrin / 0’cool
Please read this thread from the start. I really feel pity about your thought process & I really wonder about your advice & of course the maturity.
Go read the thread completely where I’ve clearly defined what we do at each of the PDCA phase. Each of this phase is a sub-process of it’s own. Why do you feel that one can’t…[Read more] -

Hi Elbrin,
That is a valuable note. However I am looking for the Process ( & not the product ) improvement using the DMAIC.
What if I use DMAIC for each of the PDCA phase..? With this I can set, measure, analyse,improve & control all the four phases giving a better process stability.
My question is, if I do the DMAIC four times ( One each f…[Read more] -

Hi Elbrin,
I think we are moving close to the target. Can you please describe this a bit. Can you give a rough mapping between the PDCA & DMAIC..?
Why do you feel that the PDCA can be applied only at the Analyse & Improve phase..?

Ranjan replied to the topic DMAIC for Software Quality in the forum General 16 years, 3 months ago
Thnx, Sanjay !
Just to describe a bit, each stage i.e. P-D-C & A has different inputs & outputs. How can I use the DMAIC by keeping the P-D-C-A intact..? Or do I need to replace the P-D-C-A by DMAIC..?
If I reatin the P-D-C-A then do I need to apply the DMAIC at every phase..?

Everyone —
Thanks for the help!
Just to clarify, my problem is not production process related, not in terms of usage of machinery.
Production for me means deliverables, like procesing of applications online etc. From that standpoint, i find AB’s suggestion great. I am not sure how much of OEE i can use.

Ranjan replied to the topic Phd Topic in Six sigma in the forum General 18 years, 3 months ago
shiv
why don’t you try to research on the standard sigma shift and bring out ways to reduce it.
people have accepted it as it is but there must be ways to reduce (if not remove) that variation.
