Standard Deviation - (Used in Activity Duration Est.
Sigma=Pess-Optim/6
3 Point Estimates - (Pert Estimates)
Pess+(4xRealistic)+Optim/6
Critical path
The combination of activities that, if any are delayed, will delay the project's finish.
Purpose of critical path method
1. Calculate project finish date
2. Identify individual activities' float times. (How much they can slip without delaying the project.)
Schedule Compression - Types
Crashing
Fast tracking
Schedule Crashing
Adding resources in order to complete activity more quickly. May increase cost.
Schedule Fast Tracking
Reorder activity sequence so that some of the activities are performed concurrently. Usually increases risk, as discretionary dependencies are being ignored.
What if schedule analysis
Typically uses Monte Carlo analysis to predict likely schedule outcomes and identify areas of highest risk.
Resource leveling
Resource needs matched up with organizations ability to supply resources. (If your plan calls for 8 programmers and you only have two, you need to lenghthen the task duration to account for fewer resources being available.)
Critical chain method
Adds buffers between activities to allow for uncertainties. Goal is to allow project to complete on schedule, despite uncertainties.

Early Start Date
Earliest date the activity can start if everything takes as long as planned.
Earliest finish date
Early start date+duration-1
Late start
Early start+float =Late start
Late finish
Late start+activity duration-1
Early Start & Early finish are what kind of pass?
Forward pass, since you start from the beginning to figure them.
Late Start and Late Finish use what kind of pass?
Backward pass, as you start from the end and work toward the beginning.
Free float
Amount of time an activity can be delayed without affecting the early start date of subsequent dependant activities.
Negative float
Activity's finish date happens before its start date. Says that the schedule has problems.
Activity on Arrow Diagram
Network diagram where activities are represented by arrows. Always shown with finish to start relationships, where one activity ends and the other begins. Uses dummy activities that can have zero length. Represented by dotted lines.
Activity decomposition
Like scope decomposition, but final result is an activity list.
Activity list
Every activity that will be performed on the project.
Activity Duration Estimates
Probable number of periods, weeks, months,etc., that the activity should take. Should give a range - 1 wk + or - 3 days, for instance.
Analgous estimating
Used when little data is available, it compares this project with a previous one.
Backward pass
Method for calculating late start and finish.
Critical path
Shortest path through the network diagram. Show activites with greatest risk for delaying the project.
Dependencies
Activities that must be completed before other activities are either started or completed.
Mandatory dependency
Hard logic. Must be followed in sequence.
Discretionary dependency
Soft logic. Best practices dictate that activities are done in a certain order. Not mandatory, recommended.
External dependency
Dependency relying on factors outside the project. Eg. zoning approval for building, weather for rocket launch.
Dummy activity
Found only on 'activity on arrow' diagrams. O length, used to show a relationship. Shown with dotted line.
Duration compression
Two main types:
Crashing
Fast tracking
Crashing
Adding resources to speed things up. Increases cost.
Fast tracking
Ignore discretionary dependencies and do things concurrently to speed project completion. Adds risk to project.
Delphi technique
Means of gathering expert opinion where participants don't know who the others are. Seeks to eliminate group think to get participants' real opinions.
Expert judgement
A method of estimating in which experts are asked to provide input into schedule.
Float
How much time an activity can be delayed without affecting the project's finish date.
Free float
Free slack. How much time an activity can be delayed without affecting the early start date of subsequent dependant activities.
Hueristics
Rules for which no formula exists.
Forward Pass
Method for calculating early start and finish dates.
Lag
Delay between an activity and the next, dependent one. Eg. Pouring concrete and waiting 3 days before building on it.
Lead
Starting a subsequent activity before its predecessor has finished. Like in relay race.
Mathmatical analysis
A technique showing scheduling possibilities where early and late start and finish dates are calculated without looking at resource estimates.
Milestones
High level pints in schedule used to track and report progress. Usually have no time associated with them.
Monte Carlo Analysis
Computer simulation that throws a high number of 'what if' scenarios at the project schedule to determine probable results.
Network diagram
A method of diagramming project activities to show sequence and dependencies.
Precedence Diagramming Method
also called Activity on Node.
Network diagram where boxes represent activities and arrows are used to show the dependencies between the activities.
Reserve Time
Contingency. A schedule buffer used to reduce schedule risk.
Schedule baseline
The approved schedule that is used as a basis for measuring and reporting. Includes original project schedule and approved updates.
Variance analysis
Comparing planned vs. actual schedule dates.

Cost of Quality
Cost Estimating Types - Bottom up Estimating
Creates separate estimate for each schedule activity and aggregates them to summary nodes on the WBS. Highly accurate but time consuming.
Cost Estimating Types - Parametric Estimating
Best for linear, scalable projects. Uses cost per unit to extrapolate cost. Eg, if it costs $4 mill. to build a mile of road, it would cost $32 million to build 8 miles of road.
Cost Estimating Types - Vendor Bid Analysis
Analyse vendor bids to understand project costs.
Cost Estimating Types - Reserve Analysis
Reserve monies, also called contingency, is added as a buffer against slippage. Reserve analysis looks at whether reserve is sufficient.
Cost Estimating Types - Cost of Quality (COQ)
Looks at the costs realized in order to acheive quality. (Cost of Poor Quality, on the other hand, looks at costs incurred due to quality standards not being met.)
