What is Rolling Wave Planning?
Concept that utilizes the progressive elaboration planning in planning.
What is Control Account?
A point placed in a WBS above the work package level to help estimating when all the details aren’t immediately available at the work package level.
What is Planning Packaging?
The planning package is a piece of the WBS between the control account and the work package.
Enter cards about Sequence Activities.
TBD
What is a network diagram?
A network diagram is a schematic of project activities and is the tool used to evaluate schedule compression techniques such as crashing and fast tracking.
What are the five types of diagramming types?
Precedence Diagramming Method (PDM) Activity on Node (AON) Arrow Diagramming Method (ADM) Activity on Arrow (AOA) Activity on line (AOL)
What is the GERT diagramming?
Diagramming technique that uses feedback loops as iterations are completed.
What are four types of predecessors?
Finish to start: A must be completed before B begins
Finish to Finish: B cannot finish until A is finished
Start to start: When A starts, B can start
Start to finish: A starts before B finish
What is lag?
Lag is delay between activities
What is lead?
Use lead when something can begin bf its predecessor is done.
What are the inputs to Estimate Activity Resources?
- Schedule mgmt plan
- Activity list
- Resource calendar
- Risk register
- Activity cost est
- Activity attributes
- EEFs
- OPAs
What are tools and techs for Estimate Activity Resources?
1 Expert judgement 2 Alternative analysis 3 Published estimating data 4 Bottom up estimating 5 Proj mgmt software
What are outputs for Estimate Activity Resources?
Activity resource reqs
Resource breakdown structure
What is a resource breakdown structure?
Displays a breakdown by resource type across organizations
What are four different types of estimating methods?
1 Analogous (aka Top down): Time or cost est that has no signif detail base on a past project. Advantage is that it can be done quickly.
- Bottom up: Starts with lowest level of detail and works upwards to get total estimate. Very detailed but time consuming.
- Parametric: Est based on existing parameter usu based upon industry standard or experience.
- Computerized: Computerized tool that simulates project outcome.
- Computerized - Monte Carlo
What is PERT?
A weighted average approach that uses three activities per activity.
Optimistic, pessimistic, most likely. Such that:
(O+P+(4xM)) / 6
What are inputs to Estimate Activity Durations?
Schedule mgmt plan Activity list Activity resource reqs Resource calendar Risk register Resource breakdown structure Proj scope stmt Activity attributes EEFs OPAs
What are tools and techs for Estimate Activity Durations?
Expert judgement Analogous estimating Parametric estimating Three point estimating Group decision making techs Reserve analogous
What are inputs to develop project schedule?
Schedule mgmt plan Activity list Project schedule network diagram Activity resource reqs Resource calendar Activity duration estimates Risk register Project staff assignments Resource breakdown schedule
What are tool and techs to develop project schedule?
Schedule network analysis Critical path method Critical chain method Resource optimization techiques Modeling techniques Lag and leads Schedule compression Schedule tool
What are outputs to develop project schedule?
Schedule baseline
Project schedule
Project calendar
What is the critical path method?
Used with scheduling environments in which a forward pass establishes the earliest the activities can start and finish and a backward pass establishes the latest activities can start and finish.
What is slack?
Amount of time that an activity can slip or be delayed without delaying the finish date of the project. If an activity has no slack its on critical path and if it slips, it pushes out the finish date.
What is schedule compression techniques?
After schedule has been put together you may have to compress teh schedule to achieve an aggressive time goal.
Two main techs are fast tracking and crashing.
Crashing - Puts more pp on the critical path items, excluding any resourcing activities
Fast Track - Analyzes the network diag and sequencing of the activities to take into considerable benefits from adjusting the sequence to accelerate completion of work.
What is critical chain method?
Emphasizes resource flexibility by using duration buffers for resources and leveling over the course of the project to accommodate limited resources.
What is resource leveling?
Levels activities / task in a given day / week based on number of people available on that day / week.
What is resource smoothing?
Similar to resource leveling it that it removes peaks/valleys but the diff is the focus on predefined limits rather than just preventing overallocation of resources.
What is a logic bar chart?
Also called the Gantt chart used to track day to day details of the project.
What is a milestone schedule?
Typically used in executive reporting (summary of details) - each milestone has 0 duration.
What is a summary schedule?
Shows an aggregate view of the various activities at the summary level.
What is a hammock activity?
Summary activity that encompasses all of the tasks or activities beneath it.
What are the inputs to Control Schedule?
Proj mgmt plan Proj schedule Work performance data Project calendar Schedule data OPAs
What are the tools and techs to Control Schedule?
Performance reviews Proj mgmt software Resource optimization techs Modeling techs Leads and lags Schedule compression Scheduling tools
What are the output to Control Schedule?
Work performance information Schedule forecasts Change requests Project mgmt plan updates OPA updates
What is formula for Time standard deviation?
(P-O)/6
What is time formula for variance?
((P-O)/6)squared
What is time formula for weighted average?
