Input to plan schedule management process?
OPA
eEF
PMP
Project Charter
Processes of time management?
- Plan schedule management
- Define activities: activities list
- Sequence activities: id & document in project schedule network diagram relationship among activities
- Estimate activity resources
- Estimate activity duration
- Develop schedule
- Control schedule
Tools of plan schedule management?
Analytical techniques
Expert judgement
Meetings
Output of plan schedule management process?
Schedule management plan:
-How to management plan
-Define criteria and process to develop, monitor & control e.g:
Level of accuracy
Performance measurement rules. EV, spi, sv
Reporting formats
Inputs to define activities process?
Schedule management plan
Scope baseline: project scope statement, wbs & wbs dictionary
OPA
EEF
Tools of define activities process?
Expert judgement
Rolling wave planning - iterative planning based on progressive elaboration / plan as you go
Outputs of define activities process?
- Activities list - lower lvl than wbs
- Activities attributes - description, relationship between activities and resourcing required
- Milestone list - important checkpoints of the project
Inputs to sequence activities process?
Activity list Activity attributes Milestone list Schedule management plan OPA EEF
Tools of sequence activities process?
- Precedence diagramming method (PDM) or network diagram
- Dependency determination
- Leads and lags
Outputs of sequence activities process?
Project schedule network diagram
Project document updates
Dependency determination - four major dependencies?
- Mandatory - often legally required.
- Discretionary - preferred logic.
- External - beyond the team’s control.
- Internal - within the team’s control.
Lead and lags?
Lead = start an activity before it’s predecessor is finished
E.g.
FS-5 days
Lags = delay before successor can start
E.g.
FS+3 days
Inputs to estimate activity resources process?
- Schedule management plan
- Activity list
- Activity attributes
- Resource calendars
- Risk register
- Activity cost estimate
- EEF
- OPA
Tools of estimate activity resources process?
- Expert judgement
- Alternatives analysis
- Bottom up estimating
- Published estimating data
- PM software
Outputs of estimate activity resources process?
- Activity resource requirements
- Resource breakdown structure - hierarchical structure of resources, organised by resource category and resource type
- Project document updates
Inputs to estimate activity duration process?
Schedule management plan Activity list Activity attributes Activity resource requirements Resource calendar Project scope statement Risk register Resource breakdown structure OPA EEF
Tools of estimate activity duration?
Expert judgement Analogue estimating Parametric estimating Three point estimating Group decision making Reserve analysis
Outputs to estimate activity duration process?
Activity duration estimates
Project document updates
Analogous (top down estimate)?
Estimating based on previous project activities
Least accurate
Least time consuming
Parametric estimating?
Simple maths relationship estimating
Three point estimating?
By default = beta distribution
(O+4ML+P)/6
Triangular distribution
(O+ML+P)/3
Standard deviation of beta distr.
(P - O)/6
Reserve analysis?
Contingency reserve - known unknown
Management reserve - unknown unknown
Inputs to develop schedule process?
Schedule management plan Activity list Activity attributes Milestone list RBS Project scope statement Risk register Resource calendar Activity resource requirements Project schedule network diagrams Project staff assignment
Tools to develop schedule process?
Schedule network analysis Critical path method Critical chain method Resource optimisation technique Modelling technique Leads and lags scheduling tool
CPM definition?
Longest sequence activities in the project
Minimum duration of the project
Delay in cp activities will delay project completion
CCM definition?
Used to account for limited resources and project uncertainties.
CCM focuses on resource allocation, optimization and levelling and activity duration uncertainty on critical path,
CCM add duration buffers to any schedule path.
Outputs to develop schedule process?
Schedule baseline Project schedule Project calendar PMP updates Schedule data
Inputs to control schedule process?
PMP Project schedule Work performance data Project calendars Schedule data OPA
Tools to control schedule process?
Performance reviews Project management software Resource optimization technique Modelling technique Leads and lags Schedule compression Scheduling tool
Outputs to control schedule process?
Work performance info Schedule forecast Change request PMP updates OPA updates Project document updates
CPM free float facts?
Free float = ES(s) - FS(p) - 1
All float is total float = time an activity maybe delayed or extended without affecting total project duration.
Some total float is free float = time an activity maybe delayed without affecting the start of any successor activity.
Fast tracking vs crashing?
Fast tracking speed up schedule by completing activities in parallel
Crashing speed up schedule by adding resources
