Best Practices for Application Portfolio Management: Gartner

An excellent piece of research by Jim Duggan came out from Gartner today. It details how companies should approach Application Portfolio Management – and of course, why you should be interested in APM in the first place. The why is clear: as the economy has slowed, companies must uncover and replicate efficiencies while slashing wasteful spending. The oft-quoted figure of 80% of IT budgets being dedicated to ‘lights-on’ activities is a primary reason why Application Portfolio Management has become such a hot topic.

But how should you discover where to focus rationalization and follow-on modernization activities? The paper relates a number of suggestions. The major thrust is that management should assess which portions of the application portfolio to rationalize based on different perspectives. That is, you should determine the ways in which you manage your business, and then rank your applications based on these views.

For instance, we could start with the most obvious perspective: cost. What are your most expensive applications and do you need to maintain these systems? Do they overlap and can be consolidated? Are they not used by the business? Is there a less expensive architecture?

You can then quickly move to other Application Portfolio Management perspectives. It could be by organization. Are applications that are managed by expensive / low-value providers that could be re-assigned? Or the perspective could be by business process. Are there business processes that could be better managed by an external service provider? Are there applications that support defunct business processes? You can see that executing APM from different perspectives allows you to rationalize based on KPIs that matter to your organization.

There is also a significant side advantage that comes from managing by these perspectives as you focus APM and continue to refresh APM. Once perspectives are in place – and rationalization decisions may have been made – you can focus modernization activities on sub-sets of the portfolio that matter to you. High-cost and low-business value areas? High-risk and frequently-changing applications? Now, resources can be applied to the right area. You may decide to deploy richer code analytics at this stage to get a complete picture about how developers should be concentrated.

Further, these perspectives –especially once placed onto the software – offer a ‘filtration mechanism’ for metrics as you collect them for APM. Looking for cost data on a business process, or risk information about applications managed by a particular organization? The perspectives provide the means to get these business answers. The result is highly business-centered development decisions.
