PDM
P 177
TAKE LONGEST DURATION OF EACH ACTIVITY AND ADD.
CRITICAL PATH
NO FLOAT AND LONGEST DURATION OF ACTIVITIES.
P 177
FOR ESTIMATING DURATION WITHOUT WEIGHT USE WHAT?
USE SIMPLE AVERAGE
ROR = Rate of Return
(total return/initial invenstment)*100/years
SPI formula
EV/PV
EV Formula
SPI*PV
EXPECTED PROFIT FORUMLA
EACH ALTERNATIVE =PERCENTAGE*DOLLAR AMOUNT OF PROFIT
THEN ADD ALL ALTERNATIVES
P 339
FFP = FIRM FIXED PRICE
CONTRACT TYPE FOR FIXED - SCOPE PROJECT
FPIF=FIXED PRICE INCENTIVE FEE
CONTRACT TYPE WHEN SCOPE IS FIXED BUTH NEED FLEXIBILITY FOR PERFORMANCE GOALS
COST REIMBURSABLE
CONTRACT TYPE WHEN SCOPE CANNOT BE PRECISELY DEFINED
