The Importance of Risk Management
Risk management is the art and science of identifying, analyzing, and responding to risk throughout the life of a project and in the best interests of meeting project objectives.
Risk management is often overlooked in projects, but it can help improve project success by helping select good projects, determining project scope, and developing realistic estimates.

Project Risk Management Processes1. Risk management planning: Deciding how to
approach and plan the risk management activities for the project.
2. Risk identification: Determining which risks are likely to affect a project and documenting the characteristics of each.
3. Qualitative risk analysis: Prioritizing risks based on their probability and impact of occurrence.
Project Risk Management Processes (cont’d)
4. Quantitative risk analysis: Numerically estimating the effects of risks on project objectives.
5. Risk response planning: Taking steps to enhance opportunities and reduce threats to meeting project objectives.
6. Risk monitoring and control: Monitoring identified and residual risks, identifying new risks, carrying out risk response plans, and evaluating the effectiveness of risk strategies throughout the life of the project.
Risk Management Planning
The main output of risk management planning is a risk management plan—a plan that documents the procedures for managing risk throughout a project.
The project team should review project documents and understand the organization’s and the sponsor’s approaches to risk.
The level of detail will vary with the needs of the project.

Risk documentation
Contingency and Fallback Plans, Contingency Reserves Contingency plans are predefined actions that the
project team will take if an identified risk event occurs.
Fallback plans are developed for risks that have a high impact on meeting project objectives, and are put into effect if attempts to reduce the risk are not effective.
Contingency reserves or allowances are provisions held by the project sponsor or organization to reduce the risk of cost or schedule overruns to an acceptable level.
Common risk factors for IT Projects Risk factors
Lack of top management commitment to the project Failure to gain user commitment Misunderstanding the requirement Lack of adequate user involvement Failure to manage end user expectation Changing scope and objectives Lack of required knowledge/skill in the project personnel New technology Insufficient / inappropriate staffing Conflict between user departments
Broad Categories of Risk
Market risk
Financial risk
Technology risk
People risk
Structure/process risk
Risk Breakdown Structure
A risk breakdown structure is a hierarchy of potential risk categories for a project.
Similar to a work breakdown structure but used to identify and categorize risks.

Risk Identification
Risk identification is the process of understanding what potential events might hurt or enhance a particular project.
Risk identification tools and techniques include:
Brainstorming
Interviewing
SWOT analysis
Brainstorming
Brainstorming is a technique by which a group attempts to generate ideas or find a solution for a specific problem by amassing ideas spontaneously and without judgment.
An experienced facilitator should run the brainstorming session.
Be careful not to overuse or misuse brainstorming.
Interviewing
Interviewing is a fact-finding technique for collecting information in face-to-face, phone, e-mail, or instant-messaging discussions.
Interviewing people with similar project experience is an important tool for identifying potential risks.
SWOT Analysis
SWOT analysis (strengths, weaknesses, opportunities, and threats) can also be used during risk identification.
Helps identify the broad negative and positive risks that apply to a project.
Risk Register
The main output of the risk identification process is a list of identified risks and other information needed to begin creating a risk register.
A risk register is: A document that contains the results of various risk
management processes and that is often displayed in a table or spreadsheet format.
A tool for documenting potential risk events and related information.
Risk events refer to specific, uncertain events that may occur to the detriment or enhancement of the project.
Risk Register Contents
An identification number for each risk event. A rank for each risk event. The name of each risk event. A description of each risk event. The category under which each risk event
falls. The root cause of each risk.
Risk Register Contents (cont’d) Triggers for each risk; triggers are indicators
or symptoms of actual risk events. Potential responses to each risk. The risk owner or person who will own or
take responsibility for each risk. The probability and impact of each risk
occurring. The status of each risk.

Major Risks Come From Major Risks Come From Management Practices….. Management Practices…..
• Poor analysis of supplier strategy and capabilities• IT treated as undifferentiated commodity• Cash injection looked for rather than business advantage• Incomplete contracting• Difficulties constructing/adapting deals for business/technological change• Poor sourcing/contracting for new technologies • Lack of maturity/experience with long-term ‘total’ outsourcing• Failure to retain requisite capabilities/skills for active contract and relationship management• Power asymmetries developing in favour of vendor• Unrealistic expectations with multiple objectives (Source: Lacity & Willcocks, 2001)

Points
Risk Mitigations Plan
Learn from Experience Follow a the maturity model. Best Practice / Multi-sourcing approach Know what to outsource
Use the frameworks from previous classes
Performing / Strategic Focus (Not just focusing
on cost)
Time
Insourcing / Bystander (outsourcing between 1-5% of IT. Mostly purchasing of IT functions).
Forming / experimenting stage (outsourcing between 10-20% of IT activities)
Storming / Strategic decision point (Organization leaders share conflicting ideas about outsourcing and pursuing different strategy to provide IT services)
Norming / Proactive Cost Focus (Beginning to form norms and actively focusing and proactively using outsourcing for cost saving including offshore. Outsourcing 20-40% of IT activities)
