COSC 475 QUIZ 4 QUESTIONS & ANSWERS
For your semester project schedule, if you built an S-curve and a 2/3rds manpower
curve for every single activity, all 150, would the end result be an overall S-curve and
2/3rds bell curve that is not in line with the lessons portrayed and expressed in the
article? Meaning it would not result in a standard bell and S curve shape? - Answer -No
The rate at which items or units are produced or installed over a given period of time is
referred to as_________, independent of the number of man-hours consumed? -
Answer -Installation Rate
For this quiz, the paper that this article was based on was published where first before it
was made into this internet article? Which would explain the spelling of some of the
English words having a very British spelling. - Answer -Canadian Journal of Civil
Engineering
To optimize productivity of the overall project, the input of resources is varied according
to the planned timing and availability of work. This optimizing of productivity results in an
initial project build up which opens up work fronts, a period of peak loading for the
project, followed by a period of _____ ______? - Answer -Progressive demobilization
Based on Figure 3 in the article, looking at the Original baseline S-curve and comparing
it to the Actual Cost of Work Performed curve, you can see that costs at completion and
all along the curve are significantly more than originally forecast, essentially from the
beginning of the project. Since cost and performance are related, you can understand
why cost would be increasing; lower performance means higher manhours expended to
do the same work; therefore resulting in higher costs. Is this a true statement based on
what you see on the curve? - Answer -Yes
Referring to Table 1, Figure 9 and Figure 10 from the article it can clearly be seen that
the learning or repetition of any task leads to an improvement in productivity. We talked
a good deal at the beginning of the semester about historical installation rates for
companies and resource data like RS Means. So the question is, when scheduling a
project we have already built once and are building a very similar one again, since our
estimated manhours for our activities are based on historicals (including the previous
similar job) and RS Means based equations, which in theory should have captured past
site "Learning", do we need to forecast or estimate additional productivity improvements
into our project schedule based on forecast future learning? - Answer -No
In the three stages of the S-curve, when discussing productivity enhances, from the
studies presented in the article, what Stage must productivity improvement be
completed to have real effect of work to be optimized? - Answer -Phase 1
In the article there is an example given that shows the maximum on-the-job manpower
being 160% of the average manpower requirement. We have discussed this same sort
