Homework Assignment 3

Due in Week 3 and worth 30 points

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 Arrangement

      Cycle Time (hours)  
Step Description Actual Potential Difference
1 Read basic data package 4 4
2 Write, type, proof, sign, copy, and distribute cover letter 21.9 0.5 21.4
3 Queue 40 0 40
4 Lead engineer calls key people to schedule meeting 4 0.25 3.75
5 Write, type, proof, sign, copy, and distribute confirmation letter 25.4 2.1 23.3
6 Hold meeting; develop path forward and concerns 4 4
7 Project leader and specialist develop missing information 12 12
8 Determine plant preferred vendors 12 12
9 Review notes from meeting 12 12
10 Resolve open issues 106 104 2
11 Write, type, proof, sign, copy, and distribute basic data acceptance letter 26.5 0.25 26.25
  Totals 267.8 151.1 116.7

Use the data in the table above and answer the following questions in the space provided below:

What are the sources of value-added and non-value-added work in this process?

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?

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?

What do you think are the most difficult critical issues to deal with when designing a sound cycle time study such as this one?

Type your answers below and submit this file in Week 3 of the online course shell:

What are the sources of value-added and non-value-added work in this process?

Looking at the chart above and the sources of value-added and non-value-added

work in the process, tells me that it appears to be almost even across the board with

the exception of a few, such as step 2, it shows a significant amount of difference in

actual and potential times. So this also tells me the amount of work that actually

went into the final product and time invested as opposed to the potential.

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?

Some of the main opportunities to improve cycle time and actual time and with the

possibilities of potential best times is to hold training in how to be more aggressive,

maybe having the proper equipment to get the job done with less time. Also could

look at hiring more people, maybe even look at people who have more experience in

getting things done in an orderly fashion. Step 1 & 2 are where, I would start to

make changes for the better.

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?

Resolving issues has done a great with the required amount of time they had

(104) compared to what the potential time that was given so in my opinion,

there is no real need for improvements, unless they can get the time down

even less and resolve issues with the customers be satisfied.

What do you think are the most difficult critical issues to deal with when designing a sound cycle time study such as this one?

Really do not see much of an issue here with designing a sound cycle study

such as this one, there could possibly be a slight issue with gathering

information, but for the most part, don’t even see that as being an issue. If, I

had to choose something, I would say maybe ethical issues could play a factor

in any study, doesn’t have to be just this particular style of study.
