Representative POMs are described for Investment Scenario Planning at each level of maturity.

1Initial

• Practice

  Use percentage mappings as an approximate until procedures are developed i.e. if business volume increases 25%; increase IT by 25%.

  Outcome

  Reactive environment with minimal predictability and poor corrective actions, leading to budget overruns and/or over-investment (“sledgehammer to crack a nut”).

  Metrics

  • Number of outages
  • Total downtime
  • Variance from planned BAU cost
  • Helpdesk calls
  • MTTR

2Basic

• Practices

  • Quickly count the IT resources and divide by business operational measures like volume, variety, complexity, etc.
  • Measure IT resources in business terms like % cost per unit or transaction.
  • Begin mapping mapping IT resources to business operational metrics.

  Outcomes

  • The unit cost of IT is understood and industry comparisons become possible.
  • A high level understanding emerges e.g. putting an extra 4-servers will allow an extra 50% volume throughput and reduce response times to sub-2-seconds.

  Metric

  Business measures per IT resources, utilized, spare capacity, lead-time to increasedecrease.

3Intermediate

• Practice

  Undertake scenario planning using the IT Services model, identifying additional IT infrastructure requirements due to likely risk/change scenarios .

  Outcomes

  • Capacity Planning:
  • Improved IT-Business alignment
  • Improved ROI
  • Optimized cost per service
  • Scenario Planning:
  • Improved IT-Business planning
  • Reduction in risk
  • Improved business continuity plans
  • Example CP: Where should we best target part of our IT budget in order to accommodate 1200 users ?
  • Example SP: Are our remote access services capable of handling a predicted increase in usage brought about by and outbreak of avian flu?

  Metrics

  • Capacity Planning:
  • ROI
  • IT service cost per user
  • IT asset utilization
  • Stakeholder satisfaction
  • Adoption of IT service metrics by the business
  • IT service metrics
  • Storage requirements per service user (trended)
  • CPU requirements per service user (trended)
  • Bandwidth requirements
  • Scenario Planning:
  • Original predicted impact of incident vs Predicted impact following implementation of new contingency plans
  • Number of times a risk threshold is broken

4Advanced

• Practices

  • Do capacity planning (including scenario planning/rightsizing/growth planning).
  • Quantify IT cost of achieving specific business process performance levels (or business cost of failing to meet agreed performance levels), facilitating appropriate prioritisation.

  Outcomes

  • Improved basis for prioritisation of investments
  • Optimal level of investment in order to achieve target business performance levels (as opposed to excessive overinvestment or under-investment)
  • Potential to manage risk more effectively
  • Continuous improvement in IT service levels
  • Target IT investments and effort in areas where the greatest impact can be made in terms of business process capacity
  • NOTE: This insight can also be helpful in managing change from a legacy application to a new application solution (identifying bottlenecks in its adoption).

  Metrics

  • Transactions handled per IT dollar
  • IT SLAs breached
  • Business process SLAs breached
  • Business process impact (eg additional process capacity) of service investment
  • Business process impact (eg business process hours lost from SLA breaches (ie no investment)
  • Transactions handled per IT dollar
  • Number of business process transactions (or hours) lost due to IT service/component failure

5Optimized

• Practice

  Base decision making process on the outputs of scenario planning activities.

  Outcomes

  • Increased confidence in model
  • Improved capability to optimize IT

  Metrics

  • Variance (actual vs planned)
  • ROI (per IT dollar)
