Basic Statistic
Basic statistic is widely defuined in the executive summary, here below there are all the final results driven from previous
calculation.
As a basic statistic we intended:
Mean
32
Mode
33
Cp
0.497
Cp_k
0.326
Std. Dev
1.783
USL
42
LSL
31
Z Bench
0.1204
Chi Sqr
21.23658
F Distr
0.2116859
i- the results are rounded where needed
Also, the study can further include some metrics related to the performance of the process:
DPU
0.0779
TDPU
0.180447 (15.03%)
0.857123 (85.71%)
0.323324 (32.33%)
RTY
0.46214233
i-the results are rounded where needed – not for the above index and ratio
Usefull indicator for consistency are controll chart (reported below), thus and thanks tto the graph we can assume that the
process is almost stable but given the analysis based on one single year we can still achieve a 1.1/1.2 target in time performance
improvement if more data can be available for analysis.
Given, all the above metrics the analysis can continue, and moveing to the next step, Process Capability Analysis, we would use
all those metrics to reach the project scope and understand if it is feasable in long time planning.
Accurate analysis and data will be provided, by sampling too, in order to refrain and possible mistake not taken into
consideration.
