Assessing change risk “Is that really the worst that can happen?” Jon Dowell
Typical Answers… “Is that really the worst that can happen?” Server may not reboot clean Require hard boot Software installation may not work on first try Reboot & retry reinstall Users may not log off at start of change window Force disconnect users
Typical Answers… “Is that really the worst that can happen?” Entire network could go down in a cascade failure Millions lost!!! Server suffer major hardware failure during reboot and never restart Millions lost!!! Ice storm takes out all our power & data centres for months Millinos lost!!!
Real Answers… “Is that really the worst that can happen?” Human error (fat fingered change) Second set of eyes (buddy system) Pre-build script in copy/paste All related assets not identified Minimal number of services impacted Have teams on stand-by Rollback required (restore to pre-change stage) Time to restore
True Risk Understanding… “Is that really the worst that can happen?” “What could happen?” Key Steps 1.Identify Potential Problems 2.Identify Likely Causes 3.Take Preventative Action 4.Plan Contingent Actions Kepner Tregoe – Potential Problem Analysis
What could happen… Potential ProblemsAssess Threat (Probability / Severity) Likely CausesPreventative Action Contingent Action State Action… (Change Short Description) Kepner Tregoe – Potential Problem Analysis
What could happen… Potential ProblemsAssess Threat (Probability / Severity) Likely CausesPreventative Action Contingent Action State Action… Network Core Switch Replacement Kepner Tregoe – Potential Problem Analysis Users may remain logged in during replacement Entire network cascade failure New switch does not work Applications do not work properly after change HIGH / LOW MED / MED MED / HIGH V. LOW / HIGH
What could happen… Potential ProblemsAssess Threat (Probability / Severity) Likely CausesPreventative Action Contingent Action New switch does not work MED / HIGH Applications do not work properly after change MED / MED State Action… Network Core Switch Replacement Kepner Tregoe – Potential Problem Analysis No power bar outlets preventing start up Miss-configured OS causing switch to not communicate Network loop causing infinite loop / broadcast storm Port miss match Routing incorrect Response too quick for application to process Check rack prior to start of change Test in lab. Copy config to text file and past into production Second set of eyes during cabling Second set of eyes. Test in lab. Copy/paste config Test in lab Second set of eyes. Test in lab. Copy/paste config Roll back to old switch by re- installing into rack, re-cabling, & turning on. (1 hr) Use DRP application service to complete critical work (8 hrs)
Responsiveness versus control “How quick is too quick?” Shawn McKenzie
Change Management is Schizophrenic * Balance of control and responsive To manage and control changes to the live environment using standard methods and process... while minimizing the risk and impact of change related issues To efficiently and promptly handle changes...
Building consensus on The Balance How can we communicate the importance of risk control without creating a fear of approval 'Red Tape"? Responsiveness to Business need is important, but how would a business-hours Change-related outage affect Operations? Raising the Spectre of a Black Monday
Building consensus on The Balance Would having Change Implementations 6 days a week during business hours create too much uncertainty? How would going to planned weekly deployment windows change the culture of IT Operations? How about every other week? Do Change Risk assessments imply Tiers of Risk/Reward?

15 Minute Break
Real Problems Lack of co-ordination between Change and Configuration management Inadequate risk and impact assessment undertaken Inaccurate / missing configuration information in CMDB so risk of wrong decisions Incomplete scope of assessment (security, business impact, availability, capacity, continuity) Staff complacency – manipulate the system Urgent changes not be appropriately tested. Process seen as bureaucratic and burdensome Instituting process control over contractor support personnel or specific segments / applications Lack of tools to efficiently track changes Scope too wide for resources available to handle
