´ Scheduling and team structure
´ Risk Management

3. Project Planning
Project Planning
The overall goal of project planning is to establish a pragmatic
strategy for controlling, tracking, and monitoring a complex
technical project.
Or,
A Plan is the strategy for the successful completion of the
project. It's a description of the project steps that produce
increasing maturity of the products or processes produced by
the project.
Why?
So the end result gets done on time, with quality!

4. Why plan?
Why plan?
i. To achieve a specific goal
ii. To reduce the complexity risk of having unclear
role
iii. To increase quality of productivity
iv. To balance the triple constraints (Time, Scope, Cost)

5. Planning is essential to control
Planning is essential to control
´ An effective way to exert control is to:
´ Know where you are
´ Know where you are supposed to be
´ Take corrective action if there is a difference between
the two
´ Note:
´ You have to have a plan to know where you are
supposed to be
´ If you have no plan, you have no control

6. Primary Planning Steps
Primary Planning Steps
1. Identify project scope and objectives
2. Define and Record Requirements
3. Identify project organizational environment
´ Analyze project characteristics
´ Identify Project Team and Define Roles and
Responsibilities
4. Identify project products and activities
5. Identify Risks and Define Risk Strategies
6. Review and communicate plan
7. Obtain Plan Approval
8. Conduct Kick-off Meeting

7. Project Scope Management
Project Scope Management
´ Project scope management is one of the most critical
project management knowledge (skill) areas
´ Scope defines
´ All the work that is required to complete the project
successfully and
´ Only the work that is required, no more, no less
´ project scope management defines and controls what is
and is not part of the project work
7

8. Project Time Management
Project Time Management
´ Project time management is the project management
knowledge area concerned with analyzing the logical and
temporal relationships among the activities needed to
complete the project .
´ In a conventional methodology, the project schedule acts
as the planning backbone for virtually all other project
activities

9. Planning, Estimating, Scheduling
Planning, Estimating, Scheduling
´ What's the difference?
´ Plan: Identify activities. No specific start and end
dates.
´ Estimating: Determining the size & duration of
activities.
´ Schedule: Adds specific start and end dates,
relationships, and resources.
9
Decomposition is the process of breaking the project scope
and deliverables into smaller, more manageable
components. Decomposition is usually performed in a top-
down, hierarchical manner

10. Project Cost Management
´ Cost is a resource sacrificed or fore-gone to achieve a specific
objective or something given up in exchange
´ Project cost management includes the processes required to
ensure that the project is completed within an approved budget.
10

11. Cost Estimation Tools and Techniques
´ 3 basic tools and techniques for cost estimates:
´ Analogous or top-down: use the actual cost of a previous, similar
project as the basis for the new estimate
´ Bottom-up: estimate individual work items and sum them to get a total
estimate
´ Parametric: use project characteristics in a mathematical model to
estimate costs

12. Project Risk Management
Project Risk Management
Definitions:
Definitions:
´ Risk is the probability of incurring some net loss while
pursuing a goal.
´ Risk management is a systematic approach to
reducing the harm due to risks, making a project less
vulnerable to challenge or failure (e.g., cost or
schedule overruns, scope decrease, quality
reduction) and its resulting product more robust.

´ Projectplan
´ Projectmanagement processes
´ Technicalissues
´ Personnelissues
´ Hardware
´ Contracts
´ Political concerns
´ Business risk

´ Environmental risk

15. Three Types of Software Risk
Three Types of Software Risk
Project Risks:
Threaten the project plan. I.e. if the risks materialize, then
it is likely that the project schedule will slip and costs will
increase.
´ Budgetary/funding
´ Schedule
´ Personnel issues
´ Resources
´ Project plan
´ Project management processes
15
´ Customers
´ Requirements problems – Scope
or requirements changes
´ Project complexity and size.
´ Hardware
´ Environmental risk

16. Three Types of Software Risk
Three Types of Software Risk
Technical Risks:
Threaten the quality and timeliness of the software to be
produced.
´ Design
´ Implementation
´ Interfacing
´ Verification
´ Cutover
´ Maintenance
´ Security
16

17. Three Types of Software Risk
Business Risks
Threaten the viability of the product to be built.
´ Building a great product that no-one wants anymore.
(Market risk)
´ Building a product that no longer fits into the overall
business strategy for the company (Strategic risk).
´ Building a product that the sales force doesn't understand
how to sell.
´ Losing the support of senior management due to a change
in focus or a change in people. (Management risk).
´ Losing budgetary or personnel commitment (Budget risk)
´ Contracts
´ Political concerns
´ Legal risk
