I’ve been heavily involved in application portfolio rationalization and management (APR and APM) over the past few years. They’re complex disciplines. As a consultant, I don’t mind a bit.

In case you aren’t familiar with APR and APM:

What’s the point? Rationalizing the applications portfolio accomplishes several useful results, among them identifying and making plans for dealing with: (1) unused applications that should be decommissioned; (2) weak applications that should be improved or replaced; (3) redundant applications that should be consolidated.

That’s APR. APM? The point of establishing an ongoing application portfolio management practice is to make sure the company doesn’t recreate the applications mess once the APR process has cleaned it up.

Why “portfolio”? APR and APM are built around the idea that your applications portfolio is analogous to an investment portfolio. The corporation invests in it and expects a return.

Also, like the funds and equities that make up a portfolio of financial investments, some applications are stronger than others. The mix continually shifts as time passes, and so, just as a fund manager sells weakening equities and buys newly promising ones, the application portfolio manager should constantly re-evaluate the applications that make up the company’s application investment portfolio.

It’s a persuasive argument, to the extent that arguing by analogy is ever persuasive. But it fails on three fronts (at least).

First, in a portfolio of financial investments, each individual holding has a market value that’s its only value. But in an application portfolio, holdings have value to the extent they support business capabilities, functions, processes, and practices.

Which means determining the financial value of an individual application is a challenging exercise in creative metrics. Unless some other topic distracts me, we’ll talk about this in more depth in future columns.

Second: The holdings that make up an investment portfolio are not dependent on each other. You can sell one without that sale having even a slight impact on the value of any of the others … unless, of course, you’re Warren Buffett and lots of other people pay attention to your investment decisions. (If you are Warren Buffett … call me.)

Where was I? That’s right: Independence. In an application portfolio, few “holdings” are entirely independent of other applications in the portfolio. You can’t just sell one that’s underperforming and expect everything else to seamlessly continue, nor can you add one without having to integrate it into others.

Imagine you undertake a thorough APR assessment. Among the findings, you find seven different raw materials inventory management systems. Clearly, you need to establish a standard — either one of the seven, or an entirely new one — and consolidate.

Clearly, that is, until you take a closer look and realize each came along with one of seven business acquisitions that occurred over the past few years.

Consolidating inventory management systems means one of two alternatives — either standardizing the inventory management process across the seven independent business units that use them, or implementing an inventory management system that’s flexible enough to accommodate seven different ways of managing inventories.

Except that by the time you’ve achieved that level of flexibility the result might be just as difficult to support as, and far more disruptive than leaving the seven systems you have alone.

There’s no such thing as rationalizing the applications portfolio. My major premise is that there’s no such thing as an IT project. My minor premise is that rationalizing the applications portfolio would amount to chartering a bunch of IT projects. My conclusion: There’s no such thing as rationalizing the applications portfolio. Q.E.D.

Every single application in the portfolio is embedded in business functioning somewhere in the enterprise. Change any holding in the portfolio and you change how the business runs.

Oh, and, by the way, if you’re IT and want to rationalize the application portfolio, the portfolio changes had better result in more efficient and effective business functioning, because … aw, c’mon, you don’t need me to spell this out for you, do you?

Why not start with APM?

Here’s another binary choice in your APR/APM decision tree: You can rationalize the portfolio (APR) and then institute the means for preventing a recurrence of the problems you undertook the APR to solve (APM). Or, you can institute an APM practice and put it in charge of rationalizing the portfolio. It’s iterative and incremental APR.

APR first means documenting the current state, designing the desired future state, and planning a program to close the gap. APM first means constantly achieving better but never getting to best. But as the definition of “best” constantly changes, achieving it couldn’t be done anyway.

The KJR Conclusion: Better is better than best.
