Who is your Capacity Manager?


The Unsung Hero of IT: The Capacity Manager.  Know them, support them and use them.

Dear CIO,
As you know there are people in our IT department that make sure the company is running smoothly every day.  You’ll be familiar with the people managing the Service Desk team, and the software that they use to make the services you are responsible for efficient.  An Unsung Hero in most IT departments is the Capacity Manager.  If he gets his job wrong, none of us know until it’s too late, and it affects every customer, every employee and ultimately, the bottom line.
Capacity Management and Planning affects every system in the company.  A good Capacity Manager knows the dull and detailed stuff so others don’t have to: how many transactions every service in your company is currently handling; what the transaction times are for each type.  They also know how many transactions the business can handle before performance degrades.  They can tell you exactly what to do to make services as efficient as they can be, to handle whatever the business throws at us in the future.

I call the Capacity Manager an ‘Unsung Hero’ rather than a ‘Superhero’ for good reason.   
The Superhero flies in when chaos already reigns, disaster has already struck, and then stops things getting worse, allowing life to return to normal.  When it goes wrong in IT terms, it’s painful.  Ask these guys: http://www.pcmag.com/article2/0,2817,2373494,00.aspThe Unsung Heroes in capacity management avoid the disaster in the first place.  It might worry the Superhero as it risks putting them out of a job, but it saves a lot of time and money not to have the world collapsing around you. 
It ought to be more reassuring to know there is someone out there who is making sure that all your plans will not be in the news due to “insufficient capacity”, “unexpected demand” and “taking months to get up to speed.”  When the new service goes live, If the Capacity Manager doesn’t do their job in their usual quiet, understated fashion, we’re usually looking at headlines we don’t like to see along with emergency spend 6 to 12 months down the line and some uncomfortable meetings with our stakeholders.
To be the Unsung Hero, the Capacity Manager needs the ‘goods’: good processes in the IT department, good tools and good data. 

Perhaps the most heroic aspect of accomplishment for many of these Unsung Heroes is that they have none of these.  This person, central to the success of your entire department, is often working with a copy of Excel, and a few “cast offs” of tools purchased for other teams to do other jobs and a collection of home grown scripts and ad-hoc processes.  Think how much more he could achieve with the ‘goods’.  Quality tools and established processes might also allow a few more Unsung Heroes to emerge from within your ranks as well, lessening your dependency on that one individual.
It can be hard enough gathering together the inputs to enable successful capacity planning.  Hopefully data about the businesses plans for the year ahead comes from you or the application owners.  Some of it will be collected from testing and existing live environments.  Its value is minimal if the Capacity Manager doesn’t have the tools to process it and save the day, before the day has even started to go bad.

It can be hard to spot the Unsung Hero. 
Putting on a mask and wearing underwear outside their pants isn’t a good look for most Capacity Managers. 
This Unsung Hero should get the same or more recognition as the Superhero when it comes to IT performance and capacity.  Let’s find him before the next disaster http://blogs.thisismoney.co.uk/2011/06/tesco-banks-big-apology-wont-stop-saver-exodus.html .....and make sure he has the processes and tools to ensure our world looks good all the time.
