Question 1

Work breakdown structure WBS

Answer 1

The main purpose is to define the hierarchy of work to be performed, which forms the basis for:

Budgeting man power and resources
Scheduling
Reporting relationships and reporting project status and expenditures
Ensuring everyone in the project hierarchy, including functional managers have considered all components of the work that have to be performed carefully

Question 2

Factors shaping the WBS

Answer 2

FActors shaping the WBS include:
Environment
Business need
What deliverables or products will be produced 
New or existing technology
Levels of output expected 
First time or been done previously
Amount of risk involved

Question 3

Characteristics of the WBS

Answer 3

Characteristics of the WBS:
Describe all work that needs to be performed (verbs at activity level)
Define manageable work packages and activities that could be performed independently by responsible people unambiguously
Defines the responsibility of individuals and teams

Developing a wbs is not a mechanistic process - it involves decisions

Question 4

Developing the WBS

Answer 4

THe WBS structure can be started in a number of ways:
Using phases (level 1) followed by the products and deliverables (level 2)

Using major deliverables (level 1) followed by the work packages that deliver each deliverable (level 2)

Using sub projects or contracts (level 1) followed by the sellers contractors own wbs as part of the contracted work

Question 5

Importance of proper work definiton

Answer 5

It forms the basis for project plans and schedules

Projects are organised by organising work packages. It involves TV w assembling of resources and defeating responsibilities

The project effort is controlled by the effectiveness of people working on individual activities and tasks

Question 6

Resourcing

Answer 6

Resource planning has to do with determining what resources will be required to complete with the project. Resources include: people equipment material information

For project level resource types are allocated
For the project phase level, specific resources are allocated

Question 7

Resource allocation

Answer 7

Resource allocations is concerned with determining the best trade offs between avalajbke resources, including time, throughout the duration of the project

Question 8

Responsibilities assignment

Answer 8

R= responsible 
A = approve 
C = consult 
I = inform

Question 9

Estimation of effeort

Answer 9

When will the project be completed and what will it cost

Question 10

Estimation tools and techniques

Answer 10

Expert judgment - asking experts
Analogous estimation - use previous similar activities
Three point estimation - estimating probability distribution and determine aggressive and safe estimates.
Bottom up estimation - roll up lower level activities costs estimates to determine task costs

Question 11

Bottom up estimation

Answer 11

Activities to work packages to phase to project

Activities start at bottom and works up to final one project

Question 12

Estimation under uncertainty

Answer 12

Define what is being estimated, each participant states estimate, several rounds to work toward consensus

Question 13

Three point estimation (pert approximation)

Answer 13

Ave weighted = opt +less + 4 ml all /6

Opt = most optimistic cost estimate 
Peas = moss pessimistic cost estimate 
Ml = most likely cost estimate
