Time (week 3) Flashcards
(16 cards)
What is an ‘activity’?
Component of work done during a project.
What is a ‘task’?
Activity that needs to be done within a certain time / by a deadline
What is a ‘schedule’?
List of times that tasks are intended to take place in chronological order
Define ‘critical path’
The sequence of stages determining the longest time needed for an operation
What do EST, EFT, LST and LFT stand for?
EST: earliest start date
EFT: earliest finish date
LST: latest start date
LFT: latest finish date
What is ‘float’?
The amount of time that a task can be delayed without delaying the completion date
What are the steps of planning time management?
- Define activities
- Sequence activities
- Estimate resources
- Estimate durations
- Develop & control schedule
What are the inputs, tools & techniques, and outputs for ‘1. Define Activities’?
Inputs: scope (WBS), scope baseline
Tools & techniques: decomposition, front end loading
Outputs: activity list, milestone list
What are the inputs, tools & techniques, and outputs for ‘2. Schedule Activities’?
Inputs: activity list, milestone list
Tools & techniques: dependency diagram, expert judgement
Outputs: network diagram, Gantt chart
What are the inputs, tools & techniques, and outputs for ‘3. Estimate Resources’?
Inputs: activity list, cost estimates, resource library
Tools & techniques: alternative analysis, first principles (bottom up)
Outputs: resource requirements, resource breakdown
What are the inputs, tools & techniques, and outputs for ‘4. Estimate Durations’?
Inputs: activity list, scope statement, milestone list, resources
Tools & techniques: risk estimates, historical reviews, expert judgement
Outputs: activity durations
What are the inputs, tools & techniques, and outputs for ‘5. develop and control schedule’?
Inputs: activity list, milestone list, scope statement, resources library
Tools & techniques: critical path method, what-if analysis, performance analysis
Outputs: schedule baseline, project calendar, work performance indicators
What is the FS dependency? Give two examples
Finish to Start
B cannot start until A is finished
e.g. formwork must be completed before pouring concrete
e.g. land must be purchased before building can start
What is the FF dependency? Give two examples
Finish to Finish
B cannot finish before A is finished
e.g. rebar must be completed before inspection can be finished
e.g. laying asphalt must be complete before line painting can be completed
What is the SS dependency? Give two examples
Start to Start
B cannot before A is started
e.g. pour slab and cure slab
e.g. road excavating must start before asphalt can start to be laid
What is the SF dependency? Give two examples
Start to Finish
B cannot finish before A is started
e.g. road excavating must start before line painting can be finished
e.g. turn on machinery and turn off machinery
