Project Schedule Management Flashcards
What are the key inputs for define activity
- Project management plan
a. Schedule Management Plan
b. Scope Baseline (WBS, WBS dictionary, project scope statement)
What’s the key tools & technique for define activity
- Decomposition (breaking down work packages into smaller activities)
- Rolling wave planning (progressive elaboration)
What’s activity list
- list of all scheduled activities to complete work package
Note: each activity should map to one work package and should have identifier
What’s activity attribute
resources needed to complete activity, location of activity, cost, assumption, constraints, leads and lags, relationship with other activities
Milestone List
milestone = major accomplishment or event
What is sequence activity
Take list of activity and put them in order
What are the key inputs for scheduling activities
- Project Management Plan
a. Schedule Management Plan
b. Scope Baseline - Project Documents
a. Activity list
b. Activity attributes
c. Milestone list
d. Assumption log
What are the tools & techniques to sequence activities
- Precedence Diagramming Method
- Dependency Determination
3, Leads & Lags - Project Management Information System
What’re FS, FF, SS, SF
- Finish-to-Start (FS): finish activity A then can start activity B
- Finish-to-Finish (FF): finish both activities simultaneously
- Start-to-Start (SS): start activity A first before starting activity B
- Start-to-Finish (SF): cannot finish until activity A starts
What’s mandatory dependency
Have to finish one activity to start next activity (hard logic)
Discretionary dependencies
activities do not need to get done in specific order (soft logic)
External dependencies
dependent on activities outside of project team
Internal dependencies
depend on activities within the control of project team
What’s the output of sequencing activity

project document update (those inputs)
What are the examples of input of estimating activity duration
- Project Management Plan (e.g. schedule management plan, scope baseline)
- Project document list
a. activities: activity list, attributes, milestone
b. resource: resource breakdown structure, calendar, requirement
What are the examples of input of estimating activity duration
- Project Management Plan (e.g. schedule management plan, scope baseline)
- Project document list
a. activities: activity list, attributes, milestone
b. resource: resource breakdown structure, calendar, requirement
What’s Analogous estimating? What’s the advantage and drawback
- Historical information to assign current duration
- Quick to do
- Less accurate
What’s parametric estimating
based on historical data and variable to estimate activity duration
Three point estimate (Beta distribution)
(optimistic +4 * realistic + pessimistic)/4
What’s the formula to calculate std dev
(pess-opt)/6
What’s triangular distribution
(opt + realistic + pess)/3
Critical path activities have float
False
What is float
The amount of time that can delay activity without delaying project end date
What is resource levelling? What’s the solution and impact?
- Overallocated resources that is working on two or more activities
- Arrange in sequential order instead of parallel. might lengthen critical path
Resource Smoothing
Change the schedule without affecting critical path
What is Monte Carlo Simulation
What if scenario testing
What are two types of schedule compression
- Crashing: add more resources to activities to complete them faster
- Fast tracking: do activities in parallel instead of sequentially
Schedule Baseline
- can only be changed with approval
2. measure the progress of project schedule
Project schedule
- include start date and end date for all activities
a. Bar Chart (Gantt Chart)
b. Milestone chart: only show major deliverable
c. Project schedule network diagram
Formula of calculating float
LS-ES
OR
LF-EF
Calculation of EF
ES + Duration -1
Calculation of LS
