Running IT-as-a-Service Part 55: IBRS Infrastructure Maturity Model
Conclusion: Delivering mature infrastructure services depends on many factors. For example, the service levels may vary significantly. Some organisations opt for non-stop operations, others seek basic service levels that allow up to one hour unscheduled downtime per month (or more). The key challenge facing IT organisations reviewing their infrastructure is to strike a balance between service level, cost, quality and risks. To address this requirement, IBRS has developed an Infrastructure Maturity Model1 to help organisations understand the service components dependencies before selecting an infrastructure alternative.
