chapter 2 Flashcards
what are the 10 steps of project planning?
S I I A I E -> AR RP EP LP
- Select project
- Identify scope & obj
- Identify infrastructure
- Analyze characteristics
- Identify product & activities
- Estimate effort
- Identify risk
- Allocate resource
- review & publicize
- execute plan
- level planning
what are the 2 main causes of project failure?
- forgetting critical points
- using estimates as targets
____________ is an element of work with expected duration, cost & resources?
activity
____________ is the lowest level of work on a project?
task
what is work breakdown structure?
it is a hierarchal & incremental decomposition of a project into phases.
WBS uses __________ or __________ format?
- outline or graphical tree
list & describe the 3 types of WBS.
- process WBS
- task oriented
- project manager - product WBS
- service oriented
- eng. manager - hybrid WBS
- service & task oriented
- process produce product
list & describe techniques of WBS.
- top down
- bottom up
- analogy
- based on past experience, requires a comparable - brainstorming
- think of every task that needs to be done
- catagorize them - rollin wave
- define 1-3 levels
- gather reqs
- obtain more later
what are basis of WBS?
- network scheduling
- cost
- measurement
- control
- risk analysis
- organizational structure
define scheduling.
is a calendar that links tasks that need to be done with resources
what are the primary objectives of scheduling?
parol officer - can ride truck
- least cost
- least risk
- best time
what are secondary objectives of scheduling?
significant other - can eat apples
- communication
- alternate scheduling
- effective resource allocation
what are the steps to building a schedule?
are id computerscience oR are optimized
- allocate resource
- identify dependencies
- create the schedule
- reconcile the schedule
- add review meetings to schedule
- optimize schedule
when is a task said to have dependencies?
when it requires an activity, resource or work product that is required by a d/t task
list type of dependencies
(predecessor, current dependent)
- FS , SF (rare) , FF, SS
when creating a schedule, most use ____________ ?
gantt chart
a gantt chart shows ______, _______ & ________.
tasks, dependencies & milestones
allocating resources to tasks on critical path is done during _________ stage of scheduling?
optimization
what are techniques of scheduling?
- mathematical analysis
- netwrok diagram - bar charts
- milestone charts
- gantt chars
list types of network diagrams.
- PERT
- GERT
- CPM
__________ was developed in 1950’s?
- Network diagrams
- nigga == 50 cent
__________ is a graphical representation of tasks that need to be completed for a project?
network diagram
what are the 2 classical formats of a network diagram?
- AOA - activity on arrow
- AON - Node
on a network diagram, each task is labeled with _______ & _______?
- identifier & duration
time goes from ____ to ______ in a net diagram?
left to right
- because niggas have disease
what do +ve, 0 & -ve slack indicate?
ahead, on & behind schedule
_________ is the process of determining & optimizing the critical path?
critical path model
gantt chant was dissevered by ________ in _______ ?
charles gantt in 1971
a filled diamond indicate __________
milestones
milestones are created by entering _________
tasks with 0 duration
what guideline can be used to define a milestone?
Specific
Measurable
Assignable
Realistic
Time framed
list adv & disadv on gantt charts.
adv
- easy to create & maintain
- easy to understand
disadv
- doesn’t show interdependencies (dero ahun it can)
- doesn’t show uncertainties
___________ was developed based on the idea that estimates are uncertain?
PERT
PERT uses _________ to determine durations.
- weighted average ( expected result )
confidence interval can be determined by?
standard deviation ( s = p - o / 6)
- sall = sqrt(s1 square + s2 square …)
mention the adv & disadv of PERT.
adv - considers uncertainty
disadv - TALL Guy
- Takes time & labor
- Assuming unlimited resources is a big problem
- Large & complex projects only
- Lack of functional ownership on estimates
- Get PERT software
CPM vs PERT
- both use network diagrams
- pert - probabilistic & 3 estimates -> infrequently used
- cpm - deterministic & 1 estimate
