Flashcards in PMBOK Chapter 6 - Project Time Management Deck (46):
1

What is Project Time Management? (knowledge area)

includes the processes required to manage the timely completion of the project

2

Plan Schedule Management (process)

the process of establishing the policies, procedures, and documentation for planning, developing, managing, executing and controlling the project schedule

3

Define Activities (process)

the process of identifying and documenting the specific actions to be performed to produce the project deliverables

4

Sequence Activities (process)

the process of identifying and documenting relationships among the project activities

5

Estimate Activity Resources (process)

the process of estimating the type and quantities of material, human resources, equipment, or supplies required to perform each activity

6

Estimate Activity Durations (process)

the process of estimating the number of work periods needed to complete individual activities with estimated resources

7

Develop Schedule (process)

the process of analyzing activity sequences, durations, resource requirements, and schedule constraints to create the project schedule model

8

Control Schedule (process)

the process of monitoring the status of project activities to update project progress and manage changes to the schedule baseline to achieve the plan

9

What is a schedule model?

a representation of the plan for executing the project's activities including durations, dependencies, and other planning information

10

What is the schedule management plan?

a component of the project management plan that establishes the criteria and the activities for developing, monitoring, and controlling the schedule.

11

What are work packages decomposed to?

activities that represent the work effort required to complete the work package

12

What is rolling wave planning?

an iterative planning technique in which the work to be accomplished in the near term is planned in detail, while the work in the future is planned at a higher level

13

What is an activity list?

a comprehensive list that includes all schedule activities required on the project, also includes the activity identifier and a scope of work description for each activity

14

What are activity attributes?

they extend the description of the activity by identifying the multiple components associated with each activity

15

What is a milestone list?

a list identifying all project milestones and indicates whether the milestone is mandatory

16

What is the precedence diagramming method?

a technique used for constructing a schedule model in which activities are represented by nodes and are graphically linked by one or more logical relationships to show the sequence in which the activities are to be performed

17

What is a predecessor activity?

an activity that logically comes before a dependent activity in a schedule

18

What is a successor activity?

a dependent activity that logically comes after another activity in a schedule

19

Four types of logical relationships:

1) Finish-to-start (FS) - a successor activity cannot start until a predecessor activity has finished
2) Finish-to-finish (FF) - a successor activity cannot finish until a predecessor activity has finished
3) Start-to-start (SS) - a successor activity cannot start until a predecessor activity has started
4) Start-to-finish (SF) - a successor activity cannot finish until a predecessor activity has started

20

Four types of dependencies:

1) Mandatory dependencies - those that are legally or contractually required or inherent in the nature of the work
2) Discretionary dependencies - sometimes referred to as preferred logic or soft logic
3) External dependencies - involve a relationship between project activities and non-project activities
4) Internal dependencies - involve a precedence relationship between project activities and are generally inside the project team's control

21

What are leads and lags?

lead is the amount of time whereby a successor activity can be advanced with respect to a predecessor activity
lag is the amount of time whereby a successor activity will be delayed with respect to a predecessor activity

22

What are project schedule network diagrams?

a graphical representation of the logical relationships among the project activities

23

What are resource calendars?

a calendar that identifies the working days and shifts on which each specific resource is available

24

What is Published estimating data?

several organizations routinely publish updated production rates and unit costs of resources for an extensive array of labor trades, material, equipment for different countries

25

What is bottom-up estimating?

a method of estimating project duration or costs by aggregating the estimates of the lower-level components of the WBS

26

What are activity resource requirements?

identify the types and quantities of resources required for each activity in a work package

27

What is a resource breakdown structure?

a hierarchical representation of resources by category and type

28

What is analogous estimating?

technique for estimating the duration or cost of an activity or a project using historical data from a similar activity or project. generally less costly and less time consuming that other techniques, but it is also less accurate

29

What is parametric estimating?

estimating technique in which an algorithm is used to calculate cost or duration based on historical data and project parameters

30

What is three-point estimating?

PERT (program evaluation and review technique) uses three estimates to define an approximate range for an activity's duration:
1) Most-likely - (tM) this estimate is based on the duration of the activity, the most realistic scenario
2) Optimistic - (tO) the activity duration based on analysis of the best-case scenario for the activity
3) Pessimistic - (tP) the activity duration based on analysis of the worst-cast scenario for the activity

Expected duration, tE, can be calculated using one of two formulas:
Triangular distribution - tE = (tO + tM + tP) / 3
Beta distribution (from the traditional PERT technique - tE = (tO + 4tM + tP ) /6

31

What is reserve analysis?

contingency reserves are the estimated duration within the schedule baseline, which is allocated for identified risks that are accepted and for which contingent or mitigation responses are developed

32

What are activity duration estimates?

quantitative assessments of the likely number of time periods that are required to complete an activity

33

What is schedule network analysis?

technique that generates the project schedule model. it employs various techniques to calculate the early and late start and finish dates for the uncompleted portions of project activities

34

What is the critical path method?

used to estimate minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model

35

What is the critical path?

the sequence of activities that represents the longest path through a project, with determines the shortest possible project duration

36

What is the critical chain method?

schedule method that allows the project team to place buffers on any project schedule path to account for limited resources and project uncertainties

37

What is resource leveling?

technique in which start and finish dates are adjusted based on resource constraints with the goal of balancing demand for resources with the available supply

38

What is resource smoothing?

technique that adjusts the activities of a schedule model such that the requirements for resources on the project do not exceed certain predefined resource limits

39

What is crashing?

technique used to shorten the schedule duration for the least incremental cost by adding resources

40

What is fast-tracking?

technique in which activities or phases normally done in sequence are performed in parallel for at least a portion of the duration

41

What is a schedule baseline?

the approved version of a schedule model that can be changed only through a formal change control procedure and is used as a basis for comparison to actual results

42

What is a project schedule?

an output of a schedule model that presents linked activities with planned dates, duration, milestones and resources

43

What is schedule data?

the collection of information for describing and controlling the schedule

44

What is a project calendar?

identifies working days and shifts that are available for scheduled activities

45

What are performance reviews?

measure, compare and analyze schedule performance such as actual start and finish dates, percent complete, and remaining duration

46

What are schedule forecasts?

estimates or predictions of conditions and events in the project's future based on information and knowledge available at the time of the forecast.
