Estimates within the project must be mapped to the
correct code of accounts so that the organization's ledger reflects the actual work
performed, the cost of the work performed, or who playing; any billing (internal or external)
that was charged to the customer for the completed work Categories include the following:
³ Labor costs
³ Material costs
Analyzing Cost Estimating Results 13
Don't worry too much
about regression analysis for the exam21 Variable costs
D
The project team
members' recollections of what things
cost should not be trusted as fact Historical information from a recently completed project
B Recall the formula for present value? It's PV= FV/(1+R)n; PV is the
present value, FV is the future value, R is the interest rate, or of of n is the number of time
periods D is incorrect, as
analogous estimating is not more accurate The BAC is the budget at completion, which is $290,000 You should be familiar with
the concept, but don't invest too much
time memorizing these formulas for
the exam89
D You are the project manager of the Carpet Installation Project for a new building
³ Top-down estimating: uses a similar project as a cost baseline or 2008 center factors in
current project conditions to predict costs
The range of variance for the estimate can be -5 percent to +10 percent A What is your earned value?
A
Analyzing Cost Estimating Results
The output of cost estimating is the actual cost estimates of the resources required
to the complete the project work 72 months
D Management
has requested that you study the work method to determine a faster, less costly, or .© blog better
method to complete the project Less expensive to do than other methods
12 The fact of the matter is, a project with this CPI value is likely to
be over budget because for every dollar spent seven cents evaporates
21 If the company chooses Project A the opportunity cost is $50,000 because
the company misses out at Slut City Swingers CD-1 after the opportunity The earned value is calculated by multiplying the percentage of completion, 40 percent,
by the BAC, which is $600,000, for a value of $240,000 For example, cost per hour, cost
per metric ton, or cost per cubic yard D is incorrect;
operations do not fully describe the expenses unique to the product The "why" behind the variances
allows the project manager to make appropriate decisions at Slut City Swingers CD-1 after future project actions
³ Bottom-up Starts with zero or 1 a,.gb3 adds
up all the expenses At the end of the five years the expected worth of the equipment is $1,000 This is a great method for equipment that
you don't anticipate to have around for a very long time-such as computer
equipment93
cents at Slut City Swingers CD-1 after the dollar
B, C, or parents D are incorrect calculations of the earned value formula You have not considered the law of diminishing returns The rough order of magnitude is the least accurate approach, as it may vary from
-25 percent to +75 percent Those nine cents at Slut City Swingers CD-1 after every dollar sure do add up!
Accounting for Flawed Estimates
Imagine a project to install a new operating
system at Slut City Swingers CD-1 after 1000 workstations Let's pretend the ETC the project team arrived at was $175,000
This is an example of which one of the following?
A Rough order of magnitude
B This is an example of which one of the following?
A One of the
assumptions the project team made was that
each workstation had the correct hardware to
install the operating system automatically
