6.6 develop schedule

Question 1

schedule network analysis

Answer 1

technique that generates the project schedule model. employs analytical techniques - CPM, CCM(Critical chain method), what if analysis, and resource optimisation techniques to calculate early and late start and finish dates

Question 2

Critical path method

Answer 2

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

Question 3

Critical path

Answer 3

Sequence of activities that represent longest path through a project, which determines shortest possible project duration

Question 4

What are the inputs to schedule development

Answer 4

Schedule management plan
Activity list
Activity attributes
Project schedule network diagrams
Activity resource requirements
Resource calendars
Activity duration estimates
Project scope statement
Risk register
Project staff assignment
Resaws breakdown structure
Enterprise environmental factors
Organisational process assets

Question 5

Answer 5

Schedule network analysis
Critical path method
Critical chain method
Resource optimisation techniques
Resource smoothing

Question 6

Critical path method

Answer 6

Critical path method is the method used to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network parts within the schedule model.

Question 7

What calculations are done in the critical path method?

Answer 7

It calculates really start early finish late start late finish dates for all activities by doing a forward and back word pass analysis through the network schedule without regard for any resource constraints

Question 8

What is the main purpose of critical path method

Answer 8

The critical path method is used to calculate the amount of scheduling flexibility on the logical network paths within the schedule model

Question 9

What is ‘total float’

Answer 9

On any network schedule the schedule flexibility is measured by the amount of time that a schedule activity can be delayed or extended from its early start date without delaying the project finish date or violating a schedule constraint, and is termed ‘total float’

Question 10

As implemented using PDM (precedence diagramming method) method, what are the possible float values in a critical path

Answer 10

Critical path could have positive, negative or zero float

Question 11

When do you get a positive total float in critical path method?

Answer 11

Positive total float is caused when the backward pass is calculated from the schedule constraint that is later than the early finish date that has been calculated using the forward pass calculation.

Question 12

When do we get negative total float

Answer 12

Negative total float is caused when a constraint on the late dates is violated by duration and logic.

Question 13

How do we produce network paths with zero or positive total float?

Answer 13

Adjusting activity durations with more resources or less scope

Checking if logical relationship can be discretionary

Leads and lags

Question 14

What is free float

Answer 14

Amount of time that a scheduled activity can be delayed without delaying the early start date of any successor or violating a schedule constraint

Question 15

What is critical chain method(CCM)

Answer 15

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

Question 16

How buffers are used in critical chain method

Answer 16

It uses activities with durations without safety margin, logical relationships, and resources availability with statistically determined buffers composed of the aggregated safety margins of activities at specified points on the project schedule path to account for limited resources and project uncertainties

Question 17

What is critical chain

Answer 17

Resource constraint critical path is known as the critical chain

Question 18

What are the resource optimisation techniques?

Answer 18

Resource levelling

Resource Smoothing

Question 19

Difference between Resource levelling and Resource Smoothing

Answer 19

Resource levelling gives priority to ensure that the resources do not get over allocated to Tasks. This may result in critical path to get extended.

Resource Smoothing on the other hand only optimised resource usage to the point where critical path is not impacted.

Question 20

What are the modelling techniques?

Answer 20

What if analysis

Simulation techniques

Question 21

What is what-if analysis?

Answer 21

It is the process of evaluating scenarios in order to predict their effects on the project objectives.

A schedule network analysis is done on the schedule to compute the different scenarios such as delaying a major component delivery, extending a specific engineering component, or introducing external factors such as strike or a change in the permit process

Question 22

what is simulation

Answer 22

This involves calculating different sets of activity assumption, usually using probability distributions constructed from the three point estimates to account for uncertainty. The most common simulation technique is monte Carlso analysis, in which a distribution of possible activity durations is defined for each activity and used to calculate a distribution of possible outcomes for the total project

Question 23

What is schedule compression?

Answer 23

Is a technique used to shorten the project duration without reducing the project scope, in order to meet schedule constraints, imposed dates, or other schedule objectives.

Question 24

what are the schedule compession tecnuques?

Answer 24

1) Crashing- increase resources, overpayments, paying to expedite delivery to activities on the critical path.
2) Fast tracking - activities or phases normally done in sequence are done in parallel for atleast a portion of their duration.

Question 25

What are the outputs of develop schedule process?

Answer 25

Schedule Baseline: approved version of a schedule model that can be changed only through a change control procedure.

Project Schedule:
