Question I. Process Capability Improvement $(12$ pts$)$

i$.$ Describe a $($manufacturing or service$)$ process of your choice that you intend to improve the capacity of that process. $(4$ points$).$

ii$.$ Show a step$-$by$-$step procedure on how you would identify the sigma level of a process $(3$ pts$.)$

iii. Recommend how to improve the process to a higher sigma level by reducing errors$).(5$ pts$.)$

For example, if the process stands at the $3-$sigma level, how could you improve to a $4-$sigma level to $5-$sigma level and $6-$sigma level. $[$The Six Sigma approach is a data$-$driven approach$].$ You may present alternately a conceptual view of the process improvement. However, a six$-$sigma data analysis $($shown in the lecture$)$ is preferred.

Suggestions:

Follow the Topic $-$ Lean Six Sigma Statistical Control lecture note.

There are two case studies using two processes. You can follow one.

$($I$)$ Identify and improve the sigma level using the DMPO.

$($II$)$ Identify and improve the Six Sigma Level using the Process Capability Improvement, $C_p$

Note: I attached one student's work to illustrate Question I $($appendix$).$
