The following data consists of the actual time used and potential (the best time possible for this review process) to complete each step in the review process.
The actual times are based on the review of 30 projects. The potential times are subjective engineering judgment estimates.
Use the data in the table above and answer the following questions in the space provided below:
able: Basic Data Review for Construction Project Equipment Arrangement
Cycle Time (hours)
Read basic data package
Write, type, proof, sign, copy, and distribute cover letter
Lead engineer calls key people to schedule meeting
Write, type, proof, sign, copy, and distribute confirmation letter
Hold meeting; develop path forward and concerns
Project leader and specialist develop missing information
Determine plant preferred vendors
Review notes from meeting
Resolve open issues
Write, type, proof, sign, copy, and distribute basic data acceptance letter
1.What are the sources of value-added and non-value-added work in this process?
2.Where are the main opportunities to improve the cycle time of this process, with respect to both actual time used and the potential best times? What strategy would you use?
3.Step 10: Resolve Open Issues required 104 hours (potential) versus 106 hours (actual). Is there an OFI here? Why or why not? If so, how would you attack it?
4.What do you think are the most difficult critical issues to deal with when designing a sound cycle time study such as this one?
