I read an article in the Financial Times (Rhymer Rigby, 16th March 2014) that asked the question “Is giving 100% too much?” The article focused on productivity and effort but it struck me that the general thrust applied equally to the ITIL® Continual Service Improvement process.
The Ft article quoted Graham Allcott, author of How to be a Productivity Ninja, saying that people often look at tasks the wrong way – they focus on the detail of what they are doing, rather than the impact it has. “It is actually far more practical to think in terms of the 80-20 rule and focus ruthlessly on doing things that have the greatest impact.”
That, of course, is the essential point of the first stage of the CSI improvement process – “Understand the Vision”. What is the business mission? What are the business goals? Are the improvements we are contemplating going to deliver justifiable business value?
Just because we can make an improvement doesn’t mean that we should. The effort expended might achieve a better return if it were directed elsewhere. The cost might not be justified by the benefit to the business.
There’s an old, light-hearted, quality question. Which is the better bag: a designer leather hand-bag; or a supermarket carrier bag? The answer, of course is that it depends on the use to which it is to be put. A designer hand-bag won’t carry very many groceries and ladies would look pretty silly in the night-club dancing around a supermarket carrier bag.
The primary purpose of Continual Service Improvement (CSI) is to continually align and realign IT services to the changing business needs by identifying and implementing improvements to IT Services that support business processes. Of course, any improvement comes with a cost which must be justified by the value of the improvement.
Continual service improvement needs to consider the degree to which the portfolio meets the business needs. The value of continual service improvement is realised when there is closure of the gap between what has been promised and what is delivered. There needs to be a deliberate effort to recognise when requirements have changed and respond accordingly.
This is where we need to challenge ourselves. Is enough, enough? The law of diminishing returns and the Pareto 80:20 rule both indicate that there will be a point when further improvement is not justified. The (Act) point in the Deming cycle that directs us to seek out other opportunities – gradually and incrementally improving all that we do – for the benefit of the business as a whole.
