Kaizen - Answer-Change for the better
Cause Solution Matrix - Answer-Causes (know and unknown) and Solutions (simple
and complex)
Data - Answer-Data is facts, especially numerical fasts, collect together for reference or
information
Information - Answer-Knowledge communicated concerning some particular fact
Inferential Statistics - Answer-A set of methods used to draw conclusions or inferences
about characteristics of populations based on data from a sample
Descriptive Statistics - Answer-A method of organizing, and presenting data in a
convenient and informative way
Mean - Answer-The arithmetic average computed by summing all the values in the
dataset and dividing the sum by the number of data values
, Median - Answer-The middle number in the data set, (n/2), when arranged in ascending
order (small to large)
Mode - Answer-The most frequently occurring data point in the data set
Quartiles - Answer-Any of the three values (mean, median, mode) which divide the
sorted data set into four equal parts, so that each part represents one fourth of the
sampled population
Standard Deviation - Answer-The average distance of all data points from the mean of
the data set. Excel formula: =stdev(data set)
Variance - Answer-the square of the standard deviation. Excel formula: =var(data set) or
=standard deviation^2
Range - Answer-The largest value in a data set and the smallest value in a data set.
Excel formula: =max(data set) and =min(data set) then: =max-min
Interquartile Range (IQR) - Answer-When calculating the quartiles, you will subtract the
3rd quartile from the 1st quartile
Process Baseline - Answer-The average, long-term performance level of a process
when all the input variables in the process are running in an unconstrained fashion
Process Entitlement - Answer-The best case, short-term performance level of a process
when all the input variables in the process are centered and in control
Process Benchmark - Answer-The performance level of the process is deemed by
comparison to the best process possible. It takes us to the best that anyone has ever
done. Practically, this means researching and finding the best that has ever been done
in the industry.
DMAIC - Answer-The DMAIC roadmap is comprised of five phases: define, measure,
analyze, improve, and control. It's a data-driven process or strategy used for process
improvements. Each phase includes three steps that must be followed in succession.
Define - Answer-What problem are you trying to solve? Involves three steps:
1. Understand customer & business requirements
2. Complete the project charter
3. Complete high-level as is process map
Define Phase, Step 1: Understand customer and business requirements - Answer-In
this step, you try to define the problem from the customer's perspective.
