total float formula total float = late finish - early finish
bell curve - symmetrical distribution - 50%
chance of falling below the mean and 50%
normal distribution chance of falling above the mean
(1sigma=68.27%. 2sigma = 95.45%. 3sigma=
99.73%)
when there are 3 possible values w/ equal probability - distribution is a triangle.
triangular distribution
A= lowest value, B= highest value, M = most likely value
triangular distribution w/ more weight given to the most likely estimate (can be
beta distribution (PERT) asymmetrical). O = optimistic estimate, ML=most likely estimate, P=pessimistic
estimate
mean for a beta distribution mean = (O + 4ML + P)/6
standard deviation for beta distribution standard deviation = (P-O)/6
project mean is the sum of the means of the individual tasks. project standard
statistical sums
deviation is the square root of the project variance
used to monitor the progress of a project and is an analytical technique. uses 3
earned value management
independent values - PV, AC, EV
the budget or the portion of the approved cost estimate planned to be spent
planned value (PV)
during a given period
the total of direct and indirect costs incurred in accomplishing work during a
actual cost (AC)
given period
earned value (EV) the budget for the work accomplished in a given period
cost variance (CV) CV = EV - AC
schedule variance (SV) SV = EV - PV
cost performance index (CPI) CPI = EV/AC
schedule performance index (SPI) SPI = EV/PV
positive CV indicates, negative CV costs are below budget, costs are overrun
indicates
positive SV indicates, negative SV a project is ahead of schedule, a project is behind schedule
indicates
CPI greater than 1.0 indicates costs are below budget
SPI greater than 1.0 indicates project is ahead of schedule
1/5
, CPI less than 1.0 indicates costs are over budget
SPI less than 1.0 indicates a project is behind schedule
the amount we expect the total project to cost on completion and as of the "data

new estimate technique for finding EAC EAC = AC/new estimate for remaining work
the actual performance to date shows that the original estimates were
new estimate is most applicable when: fundamentally flawed or when they are no longer accurate because of changes in
conditions relating to the project
original estimate technique for finding EAC = AC/(BAC - EV)
EAC
actual variances to date are seen as being the exception, and the expectations for
original estimate is most applicable when: the future are that the original estimates are more reliable than the actual work
effort efficiency date
performance estimate low technique for EAC = AC + (BAC - EV)/CPI or EAC = BAC/CPI
finding EAC
performance estimate low formula is future variances are projected to approximate the same level as current variances
most applicable when:
performance estimate high technique for EAC = AC + (BAC - EV) / (CPI)(SPI)
finding EAC
performance estimate high formula is the project is over budget and the schedule impacts the work remaining to be
