W6 Flashcards
what is a project
- made up of multiple activities
- objvs outlined before proceeding with project
- specific time period to complete
- provides structure for managers to track progress
- networks are the main technique used these are PERT and CPM
project management across the organisation
PSM - once you are able to monitor activities you know when to purchase supplies
Accounting - uses info to provide a time line of expenditure
marketing - uses info to monitor progress to provide updates to the customer
project life cycle
conception - identify the need
feasibility/ analysis - costs, benefit and risks
planning - doing the project
termination - ending the project
network planning techniques
PERT - projects are uncertain you don’t know how long an activity will take so use probability factors
CPM - deterministic, understand how long activities will take so use deterministic factors
PERT - make use of probability values
3 main values will be given
1. optimistic value - if everything goes well the time it should take
2. pessimistic value - if the activity goes badly, how long it will take
3. average value - the avg. time the activity would take
CALCULATION IN PHOTO
Characteristics of PERT and CPM
- sequence of activities = one activity follows another
- identify critical and non critical activities = critical activities if delayed will effect the whole project
- estimate projects duration
- estimate slack
PERT = Activity in node
- use nodes to represent the activity
- arrows = one activity follows another
(look at diagram)
crashing
- crashing = reducing project completion time
- focus on critical path only
- may need to be shortened due to:
- transferring resources to a new project
- different deadlines
- crashing = (crash cost - normal cost) / (normal time - crash time)
