ITIL: The Prelude to Flexible Performance
In the absence of a process that enables IT to categorize and prioritize incidents based on the business impact of the event, its a free-for-all at the service desk. Without the right incident management structure and process in place, incident resolution most likely will not be in concert with the needs of the business.
In the absence of guidelines for prioritizing incidents, the service desk cannot reliably determine which incident should be resolved first. Should the ATMs be restored first, or is it more important to get the branches back online?
The answer depends on the priority of the incident as viewed by the business. IT needs the flexibility to shift its incident resolution efforts and focus based on which incident is considered higher priority by the business: the failed ATMs or the bank branch system failure.
ITIL defines priority as the combination of impact and urgency. While the bank branches being offline may be of greater impact, that problem is only half of the equation.
What if these incidents occurred on a federal holiday, when the banks are closed? Although the impact of the incident is still the same (i.e., the branches are still down), the urgency is low, since no one is trying to use the systems in the branches.
Conversely, the failed ATMs, while perhaps having a lower impact, have a much higher urgency since thats the only means for people to withdraw cash.
As a result of assessing both impact and urgency, resolving the incident that resulted in the ATMs being down would be given a higher priority over the incident that impacted the branches. The flexibility created by the structured ITIL process results in the lyrical sound of cash once again being dispensed.
Flexible Capacity Management
The structure of ITIL can also improve your IT organizations flexibility in responding to the continually changing demands for scarce computing resources.
Imagine that your business customer plans to launch a marketing campaign that will increase revenue but will also increase the traffic to your Web storefront. In the absence of a structured approach to assessing and providing for capacity needs, companies frequently are either caught off guard or over-provision their infrastructure.
Applying the ITIL capacity management principles of business, service, and resource capacity management, as well as demand management, provides IT organizations with the ability to flexibly respond to the needs of the business while doing so in the most cost-effective manner.
In jazz, riffs are the repeating, harmonic figures that form a structural framework for the improvisational piece being performed. Riffs keep the musicians on track within the theme. Think of ITIL process management techniques as the riffs that form the framework of your enterprise, giving both IT and business the flexibility and expression they need. Together, you and ITIL can make beautiful music.
