Name a few common elements of a control plan.
List of process steps where control action is required
Date the plan was created
Name of person who created the plan
Company, division, or department name
Name of person who last edited the plan
Date of last edit
Project/process name or identifier
Process owner
CTQ or metric associated with each action required
Limit specifications, or acceptable range of measurements
Unit of measurement
Method of measurement
Necessary sample size
Frequency of measurement
Person responsible for measurement
Where information is recorded
Correction actions
Associated policy and procedure documents
True or False: there is no preference for where to build in the corrective action as long as someone takes the corrective action as soon as possible
False - it is always preferable, when possible, to build corrective action at the process (task) level - meaning the person who discovers the failure can immediately take corrective action.
_____ ______ or ______ ______ _________ graphs show differences between distributions (variations) or when outliers are fairly obvious within the data.
Box plots or Box-and-Whisper graphs
(oops Ch 14) When comparing data, why is it important to only alter one attribute or input (at a time)?
You wouldn't be able to tell what the cause of any difference between data sets was. Examples of what could be altered: times of day, day of the week, processing person, teams, etc.
(oops Ch 14) The risk that a sample doesn't offer a good representation of the populate is known as the...
alpha-risk and beta-risk
(oops Ch 14) What is used to calculate p-value (probability estimate)?
information about the sample and alpha and beta risks... the probability estimate tells statisticians how likely an assumption or conclusion drawn on a sample data will be incorrect.
(oops Ch 14) Regression and correlation analysis helps Six Sigma experts understand how variables within a process might be __________.
related
(oops Ch 14) What does regression analysis help teams define?
The relationship between on independent variable - possibly an input - and one dependent variable - possibly an output. (ex. temp of oven have a relationship to whether the cake is baked correctly)
(Oops Ch 14) What does DoE stand for?
Design of Experiments - provides more granular level of details and analysis required for that level of certainty.
Name some visual controls used for visual management.Signs, 5S, matrixes and instructions (our equivalent could be decision tree/matrix), auditing boards, color coding, and safety signalsName a few of the elements in a basic control chart.A line chart of data with plot points for specific data points • An x-bar line representing the average of the data points • Lines above and below the x-bar line representing 1, 2, and 3 standard deviations from the median in either direction • An upper control limit (UCL) line at 3 standard deviations above the median • A lower control limit (LCL) line at 3 standard deviations below the medianIt's important to note the distinction between a controlled process and one that is capable of meeting customer requirements. We touched on this concept in unit 1: controlled processes don't have a lot of variation. Capable processes don't have a lot of variation and the outputs...center around a customer requirementWhat sigma level is the minimal level at which customers will be satisfied?4Cpk denotes what?Process capabilityMany organizations aim for a process capability of __ with minimal acceptance process capability at ___.2, 1.5At the end of the control phase, the Six Sigma team should celebrate and reflect. As a part of reflection, the team should also ______________________brainstorm ideas for next steps/future projects.
