A leading manufacturer of construction and mining equipment is considering placing a bid for 6 excavators. The manufacturer has just finished building the first excavator. The data for the first excavator is as follows:

Labor Hours = 6,000
Material Cost = $200,000
Labor Cost = $50/hour

The company expects a Learning Rate of 75% in building these excavators for the next 2 units, then anticipates that the time per unit levels out and little further improvement occurs.

Determine the bid that should be placed, that is, the total budget and schedule needed to complete this prospective project.

2. Tracking signals may identify the accuracy of one's estimating skills. Using the following data:
a. Compute the tracking signal for each period
b. What is the Mean Absolute Ratio (MAR) at the end of 6 months?
c. Interpret the results

Bias in Estimate Chart
Month Estimate Actual (At/Et)-1 |(At/Et)-1| MAR Tracking Signal
1 1000 950
2 1100 1040
3 1110 1050
4 1000 960
5 1150 1090
6 1100 1050

Project Management: Quantitative Methodology

See the attachment.

Please include a brief description explaining the quantitative methodology used (1 or 2 sentences), as well as, how this model helps solve a professional or personal problem (1 or 2 sentences)

Jack and Diane have different ideas about investing in their house. Diane wants to build a sunroom addition, but Jack is frugal and wants to switch to an accelerated mortgage payment to save on interest. They call Paulson & Sons, a contracting firm, specializing in home renovations and additions, for a consultation. After some wrangling amongst themselves, Jack and Diane agree to put the issue to Mr. Paulson--they tell the contractor that for the amount they're prepared to spend, $100,000.00, if he can build an addition which can yield at least a 125% return on their investment, they will proceed with Diane's preference, the addition.

I anticipate the following tasks will be involved:
1) Permit
2) Demolition
3) Framing
4) Electrical
5) Drywall, plastering
6) Flooring
7) Windows
8) Paint and wallpaper
9) Window covering
10) Final permit inspection.
