I need help with questions C and D.... preferably not just a copied and pasted answer from another question

Your company is considering a process improvement and it is currently operating at the 4.5 quality level (including the 1.5 shift).

A) If most projects pursued have an average improvement rate of 50% annually, how many years will it take to achieve 6 quality levels?

B) Is it likely the process improvement project will be adopted, based on the solution you got? (Use the exponential approach discussed in class)

C) How will your response change if improvement rate goes up by another 15% due to adoption of a process improvement automating some stages in the process?

D) Which dimensions of quality can the process improvement improve? Explain briefly (3 points)
