An intro to ITSM

Greetings!

So, assuming you are relatively new to it, I thought I would give a high level overview of what ITSM is.

ITSM is an acronym, we use a lot of these, for Information Technology Service Management.

Since the early days of I.T. there has been a concept of “managing” the services that customers were buying. Initially this was very limited to support the products (hardware or software) that were purchased and, in my opinion, was very much there to drive additional sales rather then deliver any tangible value beyond that derived from the products.

Towards the end of the 1980’s the Central Computing and Telecommunications Agency, a government department in Great Britain, developed a framework for managing IT infrastructure. This methodology was called ITIL® (IT Infrastructure Library), and was series of books that described how IT could be managed in a consistent way. It is now owned by AXELOS™.

My first introduction to ITIL® was in the late 1990’s / early 2000’s as I moved up the career ladder. At that point ITIL® v2 was out and predominantly focused on two areas Service Delivery (SLAs, BCDR etc) and Service Support. My enduring memory is sitting two very long, and handwritten, exams after 2 weeks of training, which felt quite hellish at the time.

Since then ITIL® has kept evolving with v3 coming out in 2007 and v4, the most recent iteration, coming out in 2019.

One of the things I have always found fascinating in this areas is the continual evolution of how close an “IT Department” should be to its “Customer” from a relationship and goal alignment perspective. Initially coming across as quite standoffish through to being closely interwoven with how the business operates.

Also that ITIL® has never positioned itself as a standard that must be followed to the letter. Rather you adopt the methodology and adapt it to the needs and constraints of your organisation. Thankfully this message has never changed but, what has grown up along side this methodology, are a number of other frameworks and standards, such as:

• Microsoft Operations Framework - based on ITIL, that came out in 2008
• ISO 20000-1 - the international standard for IT Service Management. This has been heavily influenced by ITIL evolution over the years and could be considered the hard stick for what “good” looks like
• IT4IT - developed by The Open Group™ who, among other areas, own the TOGAF framework for Enterprise Architecture (I am a big advocate of this) , this is a architectural model for delivering and managing IT service. There is a lot of crossover, in my opinion, between this and ITIL® v4 which makes them very complimentary
• Agile Service Management - developed by The DevOps Institute, which heavily focuses on service management process development as a “product”. Think scrum for process development and maintenance and you will get the picture.

Now, fascinating as this potted history is, it doesn’t quite answer the question of what ITSM actually is.

One definition of ITSM is

IT service management (ITSM) is a strategic approach to design, build, deliver, operate, and control information technology (IT) services offered to customers. Source: Wikipedia.

This is an ok, if somewhat dry, statement but misses a fundamental point, which is that IT, as a business function / capability, MUST be aligned with the operational, regulatory and governance needs of the business that it delivers to.

If this isn’t achieved the IT will typically be seen as a “problem child”. Sadly even today, this kind of mis-alignment between the business needs and what the “IT department” thinks it reason for existing is, still exists.

Now when you get into the world of Managed IT Services e.g. those procured by a business from a 3rd party organisation, the original definition is still ok, but there still needs to be that alignment between the consumer and provider of IT services, albeit constrained by the boundaries of a commercial agreement (contract) of some kind.

I will be expanding on some of these areas in future posts.

I will sign-off at this point but watch out for future posts and discussions.
