Anki Reinforcement Flashcards
what is a variable sampling plan?
based on measurement of a specific quality characteristics of individual items. The measured values are then summarized and compared to an allowable value, which will lead to lot acceptance or rejection.
what is a stratified plan?
type of sample selection that takes samples proportionally from different parts of the lot
what is a sequential plan?
is a plan that treats each item as a sample of one in determining to accept, reject or continue to sample
procedure of testing items in sequence and continually making the decisions on accept or reject and wether to continue after each sample
what is a double sampling plan?
see apple photos
what is cluster sampling?
when respondents are selected in groups or clusters such as a geographical cluster, it is cluster sampling
stratified sampling
population is buyers separated into subgroups state
what are general configuration audits?
reviews of the product against the engineering specifications to determine compliance
what is a software configuration audit?
should be periodically performed to ensure the software configuration management practices and procedures are rigorously followed. Procedures for this audit should be dined in a software configuration SCM plan.
what is severity?
impact or potential harm of a failure mode, identified in a failure mode and effects analysis
what is likelihood?
probability of occurrence of a failure mode, identified in a failure mode and effects analysis
what is a scatter diagram?
plot of one measure variable measured against the other, determine relationship
What are 2 process improvement techniques?
six sigma and lean
Six sigma was invented by who when?
which was another company associated with six sigma?
motorola 1985
GE implemented in all the processes all the managers
Six sigma in laymans terms
whatever tolerance you have, if you are using half that tolerance you are having six sigma performance
Piece
100-102 you use 100.5 to 101.5 instead of 2 mm you are using 1 mm
3 approaches to using sigma
Just name the 3
- statistical tool
- process
- philosophy
when you are looking for six sigma as a statistical tool you are looking for
less than 3.4 defects per million opportunities
six sigma as a process what is it?
improving a process
DMAIC
DMADV
six sigma as a philosophy
improving anything and eveyrhitng which is not ideal
an observation should not be used
if there is a violation of a customer requirement
DMAIC stands for
When is,it used
When you want to improve an existing process
Define the problem Measure the current state of the process Analyze the audit problem based on facts and figures Improve the process Control maintain the gain
DMADV
When is it used what does it stand for
What is it also called
Used in designing with a new process
Define the goal Measure the needs of the customer Analyze the options based on facts Design a new process Verify the ability to meet the target
First 3 stages the same as DMAC
Also called DFSS design for six sigma
