Schedule Flashcards
How do you calculate Triangular distribution?
E is Estimate; o = optimistic estimate; p = pessimistic estimate; m = most likely estimate
What is crash the schedule
technique used to shorten the schedule duration for the least incremental cost by adding resources.
what is SPI?
Schedule Performance Index <1 = behind schedule =1 is on schedule >1 is ahead of schedule
What is Project Float
a number that indicates the amount of time a task can be delayed without impacting subsequent tasks or the project’s overall completion.
What is free float?
The amount that a task can move without affecting other tasks. Free Float = ES2 – EF1
What is total float?
Total Float: The amount that a task can move without affecting the final project completion date. Total Float = LF – EF. Total Float = LS – ES. Both of these formulas produce the same result.
an allocation of the budget at a high level that is specifically reserved for project unknowns.
Contingency Reserve
What is called when ‘the completion of the successor activity depends on the initiation of the predecessor activity’?
Start-to-finish
What is is called when one activity — the predecessor — must be fully complete before any following — successor — activities may begin.
Finish to Start
What is Rolling Wave
Rolling wave planning is a type of project schedule that focuses on iterative work and frequent updates to the project plan. It’s a project planning technique for projects that don’t offer all the data needed to create a plan or schedule up front.
Analogous Estimating
uses information from similar projects to establish a cost estimate based on the data available
Mandatory Dependency (Hard Logic)
A mandatory dependency is a natural flow of work being done (e.g. you must give the command to print before you can print). It may be required by the contract.
What is Soft Logic?
Sometimes referred as preferential or discretionary logic. These are the kind of logic touched by the hand of the planner/scheduler.
What is the Crashing technique?
Crashing means to add additional resources to your project. Crashing requires additional budget. So you want to crash those activities that give you the biggest bang for the buck – the most schedule compression at the least cost. Both techniques only make sense if you apply them to activities on your critical path
What is CPI
he cost performance index (CPI) is a measure of the conformance of the actual work completed (measured by its earned value) to the actual cost incurred
What is Resource Leveling
Resource leveling is a project management technique that involves resolving overallocation or scheduling conflicts to ensure a project can be completed with the available resources.
Why do you ‘develop the schedule’?
create a schedule model
What is called when a successor activity cannot begin before its predecessor has started?
Start to Start
What is the difference between Project/total Float and Free Float?
total float is about project completion, whereas free float is the amount of time a task can be delayed without affecting the subsequent task on the path
What is Program Evaluation Review Technique (PERT)?
A project management planning tool used to calculate the amount of time it will take to realistically finish a project.
What is Critical Chain Method?
Change project schedule for limited resources
A technique that modifies the project schedule to account for limited resources by adding duration buffers that are non-work schedule.
What is activity on arrow in project management?
The activity on arrow (AoA) technique is a project management tool for mapping and scheduling activities, such as tasks or events. Project managers use circles, referred to as nodes, to represent each activity of a project. Each node has sections that denote the earliest and latest event start times. Can include Dummy arrows.
What does Schedule Management plan document?
Approaches for planning, executing and control the schedule and “how to” procedures.
What is Contingency Reserve?
Time that you add to your schedule as a result of risks that you have identified
What is ‘Lags?
Lag is the delay of a successor activity and represents time that must pass before the second activity can begin.
Do you include Lags in duration estimates?
NO!
Expanding the work to fill the time available is known as what?
Parkinson’s law
