time management Flashcards
processes of time management (7)
- planning schedule management
- defining activities
- sequencing activities
- estimating activity resources
- estimating activity durations
- developing the schedule
- controlling the schedule
what is used to develop a schedule management plan (3)
- expert judgement
- meetings
- analytical techniques
what does a schedule management plan include (2)
- development of project schedule model
- the scheduling methodology and tool to use when developing the project schedule model
what does an activity list include (3)
- the activity name
- an activity identifier or number
- a brief description of the activity
what does activity attributers provide (5)
- successors
- predecessors
- leads and lags
- logical relationships
- constrains
what is a milestone
a significant event that normally has no duration (a marker)
what does it take to complete a milestone
having done several activities prior
what are the things sequencing activities include (2)
- reviewing activities and determining dependencies
- determining activities leads to developing critical path analysis
3 types of dependancies
- mandatory
- discretionary
- external
what is a network diagram (PERT charts)
a schematic display of the logical relationships among project activities and their sequencing
what does arrow diagraming method show (2)
- finish-to-start dependancies
- activities in the form of arrows
what does estimating activity resources include (2)
- determining the quantity and type of resources that will be assigned to each activity
- resources are people, equipment, and materials.
what does estimating activity duration include (3)
- the actual amount of time worked on an activity plus elapsed time
- effort is the number of workdays or work hours required to complete a task
- people doing the work should help create estimates, and an expert should review them
what is a three point estimate (3)
an estimate that includes an
1) optimistic estimate (best case scenario
2) most likely estimate (expected scenario)
3) pessimistic estimate (worst-case scenario)
tools and techniques used to develop the schedule (3)
1) gantt charts
2) critical path analysis
3) PERT analysis
what symbols does a gantt chart include and explain their meaning (4)
- a black diamond: a milestones
- thick black bars: summary tasks
- lighter horizontal bars: durations of tasks
- arrows: dependencies between tasks
milestones should be SMART:
Specific Measurable Assignable Realistic Time framed
what is a critical path
the longest path through the network diagram and has the least amount of slack or float
what happens if one or more of the activities on the critical path takes longer than planned
the whole project schedule will slip unless the project manager takes corrective action
using CPA to shorten schedule
- shortening durations of critical activities/tasks by adding more resources or changing their scope
- fast tracking activities by doing them in parallel or overlapping them
what is PERT
a network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates
what estimate does PERT used
three point estimate
PERT formula *
( optimistic time + 4(most likely time) + pessimistic time ) / 6
what are the goals of controlling the schedule (4)
to know
- the status of the schedule
- influence factors that cause schedule changes
- determine that the schedule has changed and manage changes when they occur
