Business Impact Analysis
- Process Outline
- Instructions for Conducting a BIA
Objectives
In this outline:
- Learn the importance of targeting solutions at those areas with maximum impact on the business
By deciding:
- Who resources the business impact analysis team
- How to gather impact data
- What are the consequences for IT of identified business impacts
Disaster Recovery Planning (DRP)
The role of BIA in DRP
- Project goals
- Identify threats
- Business Impact Analysis
- Identify critical processes
- Identify IT resources
- Design contingencies
- Produce plan
- Test and Deploy
- Maintain the DR Plan
Purpose and Process
Purpose of Business Impact Analysis (BIA)
- To quantify effect of disruption on business operations
- Financial and functional impact
- Business-focused
- Enables or justifies decision on what to protect at what cost
- To identify and classify backup resources
- Divide the musts from the wants for assurance of business continuity
The BIA Process
- Identify main business functions
- For example, sales, marketing, finance, manufacturing, IT, et al.
- Identify major activities of each function
- Identify dependencies for all major activities
- Must include all prerequisites or facilitators
- For example, ICT infrastructure and applications
- Manufacturing facilities, raw materials, customer contact centers, etc.
- Accommodation and transportation
- Quantify consequence from the loss of prerequisites
Who is Involved?
Membership of BIA Team
- First decide who should be involved
- Senior management and board members
- Functional managers
- Divisional managers
- Site or geography managers
- Operational staff
- Board-level senior managers
- May be appropriate for small companies
- Too far from the action in large organizations
- But
- Can set corporate objectives and priorities
- Can add credibility and authority to project
Who Contributes to BIA
- Functional Managers
- Usually the most appropriate contributors
- Sales, marketing, manufacturing, finance
- Focused on a single business function
- Generally have a rational view on its place in the overall business
- May need to consult with their supervisory and operational staff to identify all touch-points on IT systems
- Divisional managers
- Divisions may often be treated individually as small companies
- Approach and format should be consistent
- Each division may wish to field its own management team
- Potential difficulty with representation of cross-divisional functions
BIA Detailed and Local Knowledge
- Site or geography managers
- Good overview of all functions
- May be appropriate to treat each site as individual company
- Approach and format should be consistent
- Operational staff
- Good knowledge of fine detail
- Need to keep in perspective
- Typically too many for workshop session
- Less cross-functional understanding
- Need to ensure level of contribution is consistent across different functional areas
How to Gather Data
Gathering BIA Data
- What data do we need to gather?
- Fundamental purpose of the function
- Activities performed to achieve the purpose
- Resources required to perform the activities
- Consequences of non-availability of those resources
- How to gather the data
- Questionnaires
- Structured interviews
- Focused workshops
- Organizing the data
- Categorize requirements
- Document the results
- Text, spreadsheets, or database
- Purpose-designed software
BIA Questionnaires
- Designing and using questionnaires
- Make it easy for targets to respond
- Convenient
- Don't have to get all players together at one time
- Results need sanity checking
- Time-consuming to achieve good results
- Can precede workshop (to set the agenda, for example)
- Need skill and care to prepare effective questionnaire and avoid pitfalls
- Leading the audience toward an answer
- Danger of poorly considered response - completed in a hurry
- Poor response rates - or not completed at all
- Frequently need to contact respondents to clarify answers
- Easy for recipients to avoid hard or unpleasant concerns
- Inability to elicit full, frank information
- "You didn't ask that!
BIA Interviews
- Structured interviews
- Time-consuming and costly
- Capable of good results
- Danger of narrow thinking
- Results need sanity Checking
BIA Workshops
- Focused workshop
- Recommended approach
- Quick
- Lower cost than alternatives
- Highly effective
- Synergy from group
- Moderation from peers in real time
- Common understanding and decision criteria
- Drawbacks
- Difficult to schedule
- Needs good facilitator
- May still need follow-up
Business and IT Perspectives
Business Perspective of BIA
- Creates a statement of
- The critical operational needs
- How quickly I need it back
- How do I meet catch-up implications after the information systems become available again?
- How much I can afford to have lost when the process is restored
- The (non-IT) resources that are essential for me to achieve my fundamental purpose
- What do I need to do to ensure their availability?
- Identifies critical business applications
- Time scales and impacts
- Document in the DR plan
- Drives the IT perspective of BIA
IT Perspective of BIA
- From an IT perspective
- Driven by the business perspective of must-have applications
- Drivers
- What are the dependencies of the application?
- What other applications are required for it to function?
- What infrastructure (hardware, software, networking, etc.) does it require?
- How soon must it be available and what is the acceptable restart position?
- What volumes, timings, and user population are required in disaster mode?
- Is there a backup regime appropriate to these needs?
- Does the application support a staged/phased recover, or is it all or nothing?
- How will we protect it during DR mode operation?
- Identifies supporting infrastructure of the critical business applications
- Document in the DR plan
Recovery Plan Document - By When?
- Time vs. Impact
- Impact increases or levels off over time
- Impact never decreases over time
Categorizing Applications
Application Categories
- Keep it simple using three categories
- 1 = essential to organization's ability to operate
- 2 = significantly reduces the organization's capabilities or profitability
- 3 = useful, but not important in the short term
- Restoring applications
- Category 1, as soon as possible within limits specified by the BIA
- Category 3, put to one side for consideration later
- Category 2, do simple cost/benefit analysis to ensure response is appropriate to need
Summary
- In this outline, we have seen that BIA concerns
- Identifying the cost of disruption in functional and financial terms
- Setting priority for restoring applications according to business needs
- Meaningful BIA is dependent on
- Appropriate contributors
- Appropriate data gathering techniques
- BIA output is viewed from two perspectives
- Business Perspective
- People, processes, non-IT resources, recovery time, musts/wants
- IT Perspective
- Technology resources required to deliver business applications in time scale demanded
