Project Time Management
Types of Estimating
1-Bottom up estimating-the work within the activity
is decomposed into more
detail.
-The resource needs are
estimated. These estimates
are then aggregated into a
total quantity for each of
the activity’s resources
2 Analogous Estimating
Analogous estimating is most reliable when the previous activities are similar in fact and not just in appearance, and theproject team members preparing the estimates have the needed expertise-Analogous estimating is generally less costly and time consuming than other techniques, but it isalso generally less accurate
Parametric Estimating
Parametric estimating uses a statistical relationship between historical data and other variables(e.g., square footage in construction) to calculate an estimate for activity parameters, such as cost,budget, and duration.
Three-Point EstimatesMost likely (tM). The duration of the activity, given the resources likely to be assigned
Optimistic (tO).The activity duration in the best-case scenario
Pessimistic (tP).The activity duration in the worste-case scenario
tE = (tO + 4tM + tP)/6
Expected (tE)
Estimate Activity Resources• Process of estimating the type and quantities of material, people,
equipment or supplies required to perform each activity.
Inputs
1. Activity list2. Activity attributes3. Resource Calendars4. Enterprise environmental factors
5. Organizational process assets
Tools & Techniques
1. Expert judgment2. Alternatives analysis3. Published estimating data
4. Bottom-up estimating5. Project management software
Outputs
1. Activity resource requirements
2. Resource breakdown structure
3. Project document updates
3 Resource Calendars
-Information on which
resources are potentially
available
-The composite resource
calendar includes the
availability, capabilities ,
and skills of human
resources
Alternatives Analysis
-Many schedule activities have alternative methods of accomplishment. -They include using variouslevels of resource capability or skills, different size or type of machines, different tools (hand versus automated), and make-or-buy decisions regarding the resource
Published Estimating Data
Several companies routinely
publish updated production
rates and unit costs of
resources for an extensive
array of labor trades, material,
and equipment for different
countries and geographical
locations within countries.
Activity Resource Requirements
requirements documentation for each activity can
include the basis of estimate for each resource, as
well as the assumptions that were made in
determining which types of resources are applied,
their availability, and what quantities are used.

• Estimate Activity Durations• Process of approximating the number of work periods to complete individual activities with estimated resources.
Inputs
1. Activity list2. Activity attributes3. Activity resource requirements
4. Resource Calendars5. Project scope statement6. Enterprise environmental factors
7. Organizational process assets
Tools & Techniques
1. Expert judgment2. Analogous estimating3. Parametric estimating4. Three-point estimates5. Reserve analysis
Outputs
1. Activity duration estimates
2. Project document updates
Reserve AnalysisDuration estimates may include
contingency reserves, into the
overall project schedule to
account for schedule uncertainty.
The contingency reserve may be a
percentage of the estimated
activity duration, a fixed number
of work periods
Activity Duration Estimates•Activity duration estimates are quantitative assessments of the
likely number of work periods that will be required to complete
an activity•2 weeks ± 2 days to indicate that the activity will take at least eight days and no more than twelve (assuming a five-day workweek).
• 15% probability of exceeding three weeks to indicate a high
probability—85% percent—that the activity will take three
weeks or less.
