Measure Phase Flashcards
What is the Measure phase?
How big is the problem?
How can I measure my project problem?
Tool 2-Output variables/measurements
What do you put in the output measurement matrix?
The CTC’s or CTB’s
What 3 things do I have to consider regarding my data?
What is the data type, data source, and data quality
What are the two types of data?
Discrete and continuous
What is discrete data?
Countable like whole numbers or people
How many data points are needed for discrete data?
100
What is continuous data?
Measurable, time or weight
How many data points are required for continuous data?
30
How can a sample size be affected? 4 things
The number
effort/time and resources
confidence
granularity/margin of error
What is the operational definition?
What is measured how, that leads to a common understanding
What is the purpose of the measurement system analysis?
To check accuracy and precision of the measurement system
What is Gage R & R?
Reproduceability and repeatability
What is reproduceability?
The testing if someone else can measure the exact same way, I did every time
What is repeatability?
The testing that I measured the exact same way every single time
What kind of data should be used for a Gage R&R?
Discrete
What are some examples of discrete graphs?
Bar chart, Peretto, pie chart
What are some examples of continuous graphs?
Scatterplot, box plot, histogram, bubble chart
What is a quick win? 4 things
Requires low effort
reversible
has a consensus among the project team
Beneficial
What are the 5 final goals of the measure phase at the gate review?
Derive the measurements
Collect data
Understand process variation
Calculate process performance
Update project charter
How many CTC or CTB’s are put into the output measurement matrix?
1–3
Which type of data is preferred in a project?
Continuous as it holds more information and can be transferred into discrete data
What statistical key figures does discrete data show you?
Proportions
What’s typical key figures does continuous data show you?
Location and spread
