Okay, where was I?
Last time I pointed out that you are not going to convince anyone to introduce configuration management if you just present a business case. There's much more to it than that. This time I'm going to discuss what goes into a business case.
Hang on! Hold the phone! Didn't I just say that the business case was not going to swing the deal? Sure I did, but I also said you have to have a good business case because sooner or later you're going to need it. Besides, if you can't make a business case why are you so convinced CM is a good idea?
That's the point isn't it? You're all gung-ho for CM, but why? If you're waving the flag you better know why and you'd best be able to justify your reasons.
People often get caught up in the emotion of a new idea. "Configuration management is an essential part of effective IT development", we are told, and so we start telling everyone that CM is a good thing and sooner or later someone says, "why?"
"What?"
"Why is it a good thing?"
"Urm. Because it is part of ITIL. And CoBit. And, erm, CMMI. It MUST be a good thing for all of these to have it."
"But why are any of those good for out situation?"
"Erm"
Believing that configuration management is a good thing means you know nothing. Knowing why configuration management is a good thing is better (hopefully you already know why CM is a good idea, if not then we need to talk some more - maybe another series of posts :) ). Knowing why configuration management is a good thing for your situation is better still. Being able to justify all of this with a solid rationale backed by defensible data, is a business case.
A business case is a formal presentation of a cost to benefit comparison to justify an action that affects your business. In short, how much are we going to save or profit by doing this?
I should note at this point that, in the course of preparing a business case you might discover that there is no saving or profit to be made in taking the proposed action. Your research may even demonstrate that the action would result in a loss. Business cases that reveal loses don't make it past the research stage. That is the value of preparing a proper business case.
What goes into a business case?
Each organisation will have their own layout for a business case, but they all amount to the same thing:
- What do you want to do?
- When do you want to do it?
- How much is it going to cost?
- How risky is it?
- What happens if it fails?
- How are you going to mitigate those risks?
- How much will we save or profit if it works?
That's basically it.
Who is going to read your masterpiece when it's done?
Again, the specifics are down to the individual organisation but in general you know that the business case will be reviewed by the stakeholders. Stakeholders will certainly include:
- The decision maker. The person who is ultimately responsible for giving the go ahead.
- A business sponsor who will take responsibility for the action on behalf of the business.
- The implementers - all the people who will actually have to make the proposed action work.
- The users - who will have to live with the consequences of the action.
All, or some, of these roles may be the same person or group.
As with any document it is vital that you understand your audience if you want them to make a decision in your favour. Your business case is the last piece in your sales pitch, it can also be a deal breaker if it is not what your audience wants (but we will have prepared them to want it, so hopefully writing the business case will be the easy part).
If you want to know why I keep emphasising the need to prepare your audience, consider the following example.
Back in March 2003 the UK government decided to join the US in a waging a war in Iraq. This decision was made by 412 MP's who voted to go to war based on what was believed at the time to be good evidence that Saddam Hussain had access to so called weapons of mass destruction (WMD's). It should be noted the 149 MPs voted against going to war and no less than 139 of the Prime Minister's own party voted for an amendment saying the case for war was not yet proven.
The evidence supporting the vote was presented in a dossier that the Prime Minister, Tony Blair, presented to parliament. It was later revealed that those rebels who wanted more evidence were right to do so. The dossier's content had been 'sexed up' to make the evidence appear stronger than it actually was. Even in this 'sexed up' state the data was, at best, questionable.
So, why did 412 apparently reasonable human beings decide that they should go to war on the basis of this proposal? Obviously individual motives will never be known fully, but it can be observed that at the time this dossier was prepared and presented everyone in the country had been subjected to a torrent of media hyperbole on the subject. Add to this the authority with which the PM assured the house of the seriousness and quality of the intelligence (which was available to only a select few first hand), and no doubt political pressure both within the House and from MP's own constituencies, and one can understand how people made a decision that in hindsight many believe to be wrong.
It was not the data in the document that was compelling but the emotional investment, manipulation and careful presentation of this by a few in power that resulting in the decision being made. Not only was the decision made, but many who made it were adamant of its correctness (as shown through media interviews at the time). This despite the paucity of evidence in their possession.
In what order should you present the information?
Assuming you are not forced to follow a specific template, here is my suggested order for presenting the information in a business case.
Firstly, consider your audience. The main audience for a business case is the decision maker. The decision maker will be a busy person (usually quite senior and your business case may be one of dozens they are asked to consider), so you must present the best case possible as quickly as possible.
Provide an executive summary. This should be no more than one page, and should preferably consist of only one or two paragraphs. The executive summary must summarise the business case for configuration management in language accessible to the decision maker. If the decision maker is a business person you must be careful to use business language when presenting your business case, and most especially when writing the executive summary. The executive summary should be the last thing that you write and should be put on the front of the business case, before any title page or content. (I often simply attache the executive summary on the front like a covering letter. That way the person reviewing the business case does not even have to open the document.)
The main body of the business case is similarly focussed. Present the essential detail first, then the supporting information, and relegate the raw data to the appendices.
- Summary
- Benefits
- Costs, including risks
- Deliveries
- Supporting case
- Benefits detail
- Cost and risk details
- Plan
- Appendices
The precise details and content of each major section will vary, but the broad outline should present the information in the order shown above.
The reason you present the business case like this is simple. You are asking someone to make a decision. A busy person wants to know four things; what am I getting, how much is it going to cost, how long will it take, what are the risks? The summary must contain all of this information. The entire summary should be presented in bullet points and take nor more than one, perhaps two, pages (but try hard for one!). If the decision maker feels that this summary does not provide sufficient detail to make the decision then they will look into the main body of the business case.
Experience shows that even fairly major decisions are often taken on the basis of the executive summary or the business case summary. Why? Because the decision maker will have canvassed opinion from trusted subordinates beforehand. They will quickly assess the business case finally presented based on the summary, but the decision will already have been substantially made based on discussions with subordinates.
What about these 'trusted subordinates'? These are the people at whom the main supporting case is aimed. These are the people who will need to be convinced of the business case and will need to pass on their confidence to the decision maker. It is to these people we shall return in the next article in this series.
