Project Schedule Management

Question 1

What are the key inputs for define activity

Answer 1

1. Project management plan
   a. Schedule Management Plan
   b. Scope Baseline (WBS, WBS dictionary, project scope statement)

Question 2

What’s the key tools & technique for define activity

Answer 2

1. Decomposition (breaking down work packages into smaller activities)
2. Rolling wave planning (progressive elaboration)

Question 3

What’s activity list

Answer 3

1. list of all scheduled activities to complete work package

Note: each activity should map to one work package and should have identifier

Question 4

What’s activity attribute

Answer 4

resources needed to complete activity, location of activity, cost, assumption, constraints, leads and lags, relationship with other activities

Question 5

Milestone List

Answer 5

milestone = major accomplishment or event

Question 6

What is sequence activity

Answer 6

Take list of activity and put them in order

Question 7

What are the key inputs for scheduling activities

Answer 7

1. Project Management Plan
   a. Schedule Management Plan
   b. Scope Baseline
2. Project Documents
   a. Activity list
   b. Activity attributes
   c. Milestone list
   d. Assumption log

Question 8

What are the tools & techniques to sequence activities

Answer 8

1. Precedence Diagramming Method
2. Dependency Determination
   3, Leads & Lags
3. Project Management Information System

Question 9

What’re FS, FF, SS, SF

Answer 9

1. Finish-to-Start (FS): finish activity A then can start activity B
2. Finish-to-Finish (FF): finish both activities simultaneously
3. Start-to-Start (SS): start activity A first before starting activity B
4. Start-to-Finish (SF): cannot finish until activity A starts

Question 10

What’s mandatory dependency

Answer 10

Have to finish one activity to start next activity (hard logic)

Question 11

Discretionary dependencies

Answer 11

activities do not need to get done in specific order (soft logic)

Question 12

External dependencies

Answer 12

dependent on activities outside of project team

Question 13

Internal dependencies

Answer 13

depend on activities within the control of project team

Question 14

What’s the output of sequencing activity

Answer 14

Project schedule network diagram

Question 15

What’s the output of sequencing activity

Answer 15

Project schedule network diagram

project document update (those inputs)

Question 16

What are the examples of input of estimating activity duration

Answer 16

1. Project Management Plan (e.g. schedule management plan, scope baseline)
2. Project document list
   a. activities: activity list, attributes, milestone
   b. resource: resource breakdown structure, calendar, requirement

Question 17

What are the examples of input of estimating activity duration

Answer 17

1. Project Management Plan (e.g. schedule management plan, scope baseline)
2. Project document list
   a. activities: activity list, attributes, milestone
   b. resource: resource breakdown structure, calendar, requirement

Question 18

What’s Analogous estimating? What’s the advantage and drawback

Answer 18

1. Historical information to assign current duration
2. Quick to do
3. Less accurate

Question 19

What’s parametric estimating

Answer 19

based on historical data and variable to estimate activity duration

Question 20

Three point estimate (Beta distribution)

Answer 20

(optimistic +4 * realistic + pessimistic)/4

Question 21

What’s the formula to calculate std dev

Answer 21

(pess-opt)/6

Question 22

What’s triangular distribution

Answer 22

(opt + realistic + pess)/3

Question 23

Critical path activities have float

Answer 23

False

Question 24

What is float

Answer 24

The amount of time that can delay activity without delaying project end date

Question 25

What is resource levelling? What's the solution and impact?

Answer 25

1. Overallocated resources that is working on two or more activities 2. Arrange in sequential order instead of parallel. might lengthen critical path

Question 26

Resource Smoothing

Answer 26

Change the schedule without affecting critical path

Question 27

What is Monte Carlo Simulation

Answer 27

What if scenario testing

Question 28

What are two types of schedule compression

Answer 28

1. Crashing: add more resources to activities to complete them faster 2. Fast tracking: do activities in parallel instead of sequentially

Question 29

Schedule Baseline

Answer 29

1. can only be changed with approval | 2. measure the progress of project schedule

Question 30

Project schedule

Answer 30

1. 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

Question 31

Formula of calculating float

Answer 31

LS-ES OR LF-EF

Question 32

Calculation of EF

Answer 32

ES + Duration -1

Question 33

Calculation of LS
