QUESTION 1
- Which of the following steps are value-added work?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.Table: Basic Data Review for Construction Project Equipment ArrangementCycle Time (hours)StepDescriptionActualPotentialDifference1Read basic data package44—2Write, type, proof, sign, copy, and distribute cover letter21.90.521.43Queue400404Lead engineer calls key people to schedule meeting40.253.755Write, type, proof, sign, copy, and distribute confirmation letter25.42.123.36Hold meeting; develop path forward and concerns44—7Project leader and specialist develop missing information1212—8Determine plant preferred vendors1212—9Review notes from meeting1212—10Resolve open issues106104211Write, type, proof, sign, copy, and distribute basic data acceptance letter26.50.2526.25Totals267.8151.1116.7 tUse the data in the table above and select the best answer

QUESTION 3
- 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?
A) Eliminate non-value added stepsB) Eliminate value-added work.C) Use time in Queue wisely to get more work doneD) Hold more meetings to ensure work is done correctly the first time.
QUESTION 4
- 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?
A) Increase the setup time to dilute the amount of work necessary. This reduced the issues up front.B) On Step 10, resolve open issues, requires 106 hours cycle time (actual) and 104 hours cycle time (potential). Resolve open issue is an opportunity for improvements. Some common causes of open issues include incomplete information during the meeting, indecisions by the project leader or manager, responsible person (or people who are the expert on the case) not present in the meeting, an organization with an improper chain of commands in decision making, etc. C) Reduce the open issues from 104 to 106 so that it is not an issue with which we should have any concern. For example, we may set up preferred vendor lists so that we can quickly reach out to our vendors for the supplies.
D) Task managers with open issue - concerns to refocus the group.
QUESTION 5
- What do you think are the most difficult critical issues to deal with when designing a sound cycle time study such as this one? Choose the best answer.
A) These problems should be addressed in all business processes so that the cycle time of the business process can be reduced. Suggestions on improving cycle time on resolving open issue include (1) well organized, well attended and well-informed path forward meeting, (2) well-established processes on “what if” analysis, (3) clearly defined organization structure for decision making power.B) The most difficult issue in the project often lies in the decision making power. People who have expert knowledge on the project may not align with a person who makes the final decision. As a result, there will be a large number of open issues left for future decisions (delay the inevitable) that cause a long cycle time.C) Resolve open issue is an opportunity for improvements. Some common causes of open issues include incomplete information during the meeting, indecisions by the project leader or manager, responsible person (or people who are the expert on the case) not present in the meeting, an organization with an improper chain of commands in decision making, etc.
