Ch6.6 - Develop Schedule Flashcards
Develop Schedule
process of analyzing activity sequences, durations, resource requirements, and schedule constraints to create the project schedule model
Develop Schedule Benefit
by entering schedule activities, durations, resources, resource availabilities, and logical relationships into the scheduling tool, it generates a schedule model with planned dates for completing project activities.

scheduling methodology and project calendar
TT for Develop Schedule (8): schedule network analysis, 4 techniques
technique that generates the project schedule model. 4 techniques: critical path method, critical chain method, what-if analysis, and resource optimization techniques
TT for Develop Schedule (8): critical path method, 4 types of starts/finishes
to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model. Schedule network analysis calculates Early Start, SS, LS, LF. Critical Path = longest path = 0 float
Critical Path Method - float - postive, negative, free
Positive total float: caused when the backward pass is calculated from a schedule constraint that is later than the early finish date that has been calculated during forward pass calculation. Negative total float is caused when a constraint on the late dates is violated by duration and logic. Free: the amount of time that a schedule activity can be delayed without delaying the early start date of any successor or violating a schedule constraint
TT for Develop Schedule (8): 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. uses activities with durations that do not include safety margins, logical relationships, and resource 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. The resource-constrained critical path is known as the critical chain.adds duration buffers that are non-work schedule activities to manage uncertainty. Focuses on managing the remaining buffer durations against the remaining durations of chains of activities.
Critical Chain Method - Project Buffer
placed at the end of the critical chain,protects the target finish date from slippage along critical chain
Critical Chain Method - Feeding Buffer
placed at each point where a chain of dependent activities that are not on the critical chain feeds into the critical chain
TT for Develop Schedule (8): resource optimization techniques (2)
used to adjust the schedule model due to demand and supply of resources. Resource Leveling, Resource Smoothing
resource optimization techniques - resource leveling
start and finish dates are adjusted based on resource constraints with the goal of balancing demand for resources with the available supply
resource optimization techniques - resource smoothing
that adjusts the activities of a schedule model such that the requirements for resources on the project do not exceed certain predefined resource limits. activities may only be delayed within their free and total float. Thus resource smoothing may not be able to optimize all resources.
TT for Develop Schedule (8): modeling techniques(2)
What-If Scenario Analysis. Simulation
modeling techniques(2) - What if scenario analysis
process of evaluating scenarios in order to predict their effect, positively or negatively, on project objectives
modeling techniques(2) - Simulation
calculating multiple project durations with different sets of activity assumptions. Using 3 point estimates to account for uncertainty. Monte Carlo analysis - distribution of possible activity durations is defined for each activity and used to calculate a distribution of possible outcomes for the total project.
TT for Develop Schedule (8): leads and lags
refinements applied during network analysis to develop a viable schedule by adjusting the start time of the successor activities. Leads advance a successor activity with respect to the predecessor activity. Lags require a set period of time to elapse between the predecessors and successors without work or resource impact.
TT for Develop Schedule (8): schedule compression (2)
to shorten the schedule duration without reducing the project scope. Crashing, Fast Tracking
schedule compression (2) - crashing
Crashing - shorten the schedule duration for the least incremental cost by adding resources. Ex: include approving overtime, bringing in additional resources, or paying to expedite delivery to activities on the critical path
schedule compression (2) - fast tracking
activities or phases normally done in sequence are performed in parallel for at least a portion of their duration. may result in rework and increased risk
TT for Develop Schedule (8): schedule tool
contain the schedule model and expedite the scheduling process by generating start and finish dates based on the inputs of activities, network diagrams, resources and activity durations using schedule network analysis.
Outputs for Develop Schedule (6): Project Documents Updates
Activity resource requirements, Activity attributes, Calendars, Risk register
Outputs for Develop Schedule (6): PM Plan Update
Schedule baseline, Schedule management plan
Outputs for Develop Schedule (6): Schedule baseline
approved version of a schedule model that can be changed only through formal change control procedures and is used as a basis for comparison to actual results
Outputs for Develop Schedule (6): Project Schedule

Outputs for Develop Schedule (6): Schedule data, 3 types
collection of information for describing and controlling the schedule. Includes schedule milestones, schedule activities, activity attributes, and documentation of all identified assumptions and constraints.
