IT Service Management - Metrics

Written by Tsvetanka Stoyanova

Metrics and the other ways to measure performance are very popular among technical people. Almost every aspect of a computer’s performance can be and is measured, however when it comes to service metrics for IT personnel and organizations this is one area that companies should pay close attention to.

Computers or machines are easier to measure because there are little to no subjective factors. But with organizations, and especially with people, the subjective factor becomes more and more important and frequently, even if the best methodology is used, the results obtained from metrics are, to put in mildly, questionable.

Who Needs IT Service Management Metrics

Metrics are used in management because they are useful. Metrics are not applied just out of curiosity but because investors, managers and clients need the data.

There is no doubt that metrics are useful only when they are true. I guess you have heard Mark Twain's quote about “lies, damned lies, and statistics” (or in this case – metrics). True metrics are achieved via using reliable methodologies. It is useless just to accumulate data and show it in a pretty graph or in animated slideshow. This might be visually attractive but the practical value of such data is null.

However, even when the best IT Service Management metrics methodology is used, deviations are inevitable. Therefore, one should know how to read the data obtained from metrics. It is also true that metrics, including IT Service Management metrics, can be used in a manipulative way, so one should be really cautious when he or she reads metrics and above all – when making decisions based on these metrics.

Where to Look for IT Service Management Metrics

There are several metric methodologies in use for IT Service Management, so you can't complain about the lack of choice. Some of these IT Service Management metrics methodologies have been borrowed (with or without adaptation) from other industries, while others have been specifically designed for IT Service Management.
Many organizations, including ITIL and ITSM regularly publish books and reports on IT Service Management and even though these are not the only organizations, which define the de-facto standards for IT Service Management metrics, there books and reports are among the top authorities in the field. A short abstract from the “Metrics for IT Service Management” book by Peter Brooks can be found here: The sample shows the TOC and includes the first couple of chapters, so if you have the time to read it, it should give you a more in-depth idea of what IT Service Management metrics are and how to use them.

In addition to the general metrics for IT Service Management, there are sets of metrics for the different areas of IT Service, such as configuration management, change management, etc. Therefore, if you are interested in measuring only a particular subarea of your IT services, you don't have to go through the whole set of IT metrics just to get the information for the area in question. Many IT consulting companies have also developed benchmarking and other methodologies that measure IT Service Management and these documents are also useful.
In addition to ITIL, ITSM, and the various consulting companies, another place where you can get IT Service Management metrics ideas from are the sites and the marketing materials (i.e. white papers) of vendors of software products for IT Service Management. Some of these vendors implement the metrics of other organizations. This is why IT Service Management metrics are often similar and sometimes they are just the same set but from a different angle, which of course can lead to different results.

There are many vendors that you can access by conducting a search on your search engine. Whenever possible get a trial version (if the vendor offers one), give it a test run and decide for yourself if what you got is what you need. As I already mentioned, IT Service Management Metrics are only useful when true. That is why you will hardly want to waste your (and your employees') time and money on a set of IT Service Management metrics, which are not applicable in your situation.

With so many metrics that lead to so many different results in the same situation, one sometimes wonders if IT Service Management metrics do actually measure one and the same thing and if they are of any good, Yes, IT Service Management metrics are useful but only when used properly.
