Many organizations want to improve on the cost, quality and agility of their IT service provision by implementing ITIL best practices, but this often seems like a daunting prospect. As is often the case, the burning question is – how do we start?
You can’t boil the ocean. Tackling 10 processes simultaneously is prohibitively complex and almost certainly doomed to failure, so the default roadmap to ITIL nirvana is to slice it up process-by-process, selecting the most urgent process (or couple of processes) for improvement first and finding a tool to that supports. This strategy makes good sense in principle and outputs a rather smart roadmap chopped up into manageable, bite-size chunks. However, there are two major pitfalls with this process-based approach:
- It draws organizations into a web of integrations and upgrade problems as an incremental approach to procurement is assumed by default.
- It ignores the fact that it isn’t 100% of a single process that would bring the most immediate value, but selected elements of multiple processes – to create a ‘thread’ of value across ITIL.
The vendor evaluation cycle
Integrating two incident and change management tools may not involve a great deal of effort, but each time an additional module is added in line with the roadmap, the cost of integration is multiplied and the pitfalls of integration become all too apparent. Each stage in the roadmap will be affected by delays, costs and risks. Implementation is delayed by vendor evaluation. Integration is often complex and requires expensive consultant time. Risk of failure is high.
Oops! You failed to plan and fell into the Incremental ITIL trap.
The Holistic Approach
Individual ITIL processes don’t exist in a vacuum. The greatest value to be gained from the ITIL framework comes from the interconnected nature of the processes. Much of this comes from the sharing of data across processes (e.g. CMDB). Implement one process in full and there is no data sharing. Implement elements of Incident, Problem, Change, Release and Config and you’re leveraging that data five times over.
By slicing ITIL horizontally and tackling the must-have elements, irrespective of which ITIL guidelines they are associated with, you can create a thread of value that spans across ITIL and takes advantage of this leveraging. Instead of taking a short-term view and putting 100% of your resources into an ‘ideal world’ Incident Management strategy, there is more to be gained by distributing efforts and tackling the must-haves for quick wins, wherever they might lie. This ‘long thin thread’ forms a solid starting platform from which you can get quick results, demonstrate the value of ITIL in action, justify further investment and develop your roadmap in a safe, stable manner.
At a lower level, there are strategies for ensuring a smooth roll-out of your ITIL roadmap. For example, look at the information you will need to capture to run process. By standardizing the information stored at an early stage you can avoid administrative issues later on. A broader view of the specific data requirements can help avoid later projects to realign. It’s a lesson that organizations often learn in hindsight and one of the areas where a consultant can really help out.
Holistic ITIL gets the "Pareto Middle-Distance Stare of Approval"
Planning is, as ever, critical to enabling this holistic path to value. Work out what you need now, but also look at what you want in the long term from your ITSM strategy. Having a 3-5 year view may not be of great use to you now, but it can certainly help avoid some of the many pitfalls in the future. Factor this into your vendor selection and you stand a better chance of supporting your long term goals without getting stuck in a quagmire of integrations projects, upgrade paths and administration overheads. Evaluating toolsets against how they can support your extended roadmap is the key to avoiding many of these problems in the future. How many vendors do you need to work with to enable your plan? Fewer vendors means fewer of the issues that plague enterprise IT solutions initiatives. Selecting a vendor with comprehensive support for ITIL processes can mean that you don’t get the best-fit for each one, but it’s unlikely that your ITSM needs vary more than 20% from any other organization in the same industry vertical and gaining 80% of the value from 6 processes is better than 99% from just one.
Remember, ITIL is a means to an end. Don’t just focus on applying ITIL. Go for breadth, instead of depth, to leverage process overlap and interconnectivity. Focus on the parts of ITIL that are of value to you and prioritize them in terms of value to the business as a whole. In these days of economic flux, IT needs to be seen as an asset to the business.
