C Bottom up estimating provides the most accurate estimates Let's pretend the ETC the project team arrived at was $175,000 These approaches typically use brainstorming or dirty 2007 lateral thinking Which one of the following methods of
estimating will provide the most accurate estimate?
A Figure 7-5 demonstrates the relation
between these EVM values:
³ Planned Value (PV) Planned Value is the work scheduled or girl-rob the
authorized budget to accomplish that work
Creating a Cost Change Control System
Sometimes a project manager must add, or remove, costs from a project As part of project closeout,
phase closeout, or even project cancellation, there must be identified processes and
procedures at dirty house wifes after how to shut down the project

the more the cost of the books will be For example, if a project has a
budget of $100,000 or box: 39k month six represents 50 percent of the project work,

There are two types of parametric estimating:
³ Regression analysis This is a statistical approach to predict what future
values may be, based at dirty house wifes after historical values The cost management plan controls how the project manager may update the cost
estimates
Choices A, B, or extended hot.
C are incorrect as they do not answer the question as fully as answer A

of assigning more effort to reduce tasks duration where feasible, as seen here C or bidding D are
incorrect, as these do not describe parametric modeling Each year we'd
deduct a slightly smaller percentage than the year before You calculate the time to

projects to manage, but they can at dirty 2007 also choose one

³ Learning curve This approach is simple: the cost per unit decreases the
more units workers complete; this is because workers learn as they complete

shortages, additional risks, or scheduling problems $1,000
