"ECM is dead." "Content Services are the next generation." "I've got a brand-new pair of roller skates."
If you think that last quote is a non sequitur, you're right! But so, I'd argue, are the other two, because neither speaks directly to what both really are all about:
Improving the "care and feeding" of your business-critical information.
You know what else? I bet a large majority of organizations wrestling with information management issues today haven't even heard of content services – and most of these probably aren't familiar with ECM either.
This is not a criticism; if anything, it's a compliment because they're probably wrapped up in their day-to-day and don't have time to be distracted by such things.
It is a caution of sorts, though, for some in the professional market-watching game – and their devoted followers – who think what things are called, and how things are grouped and counted, is more important than how to use those things to solve business problems.
To be fair, these items probably are more important to folks like that because categorizing and quantifying market segments is what they do for a living. But for customers, the point is and must be something quite different, namely to bring order and discipline to the way their information is protected and used.
This is why the debate over content services vs. ECM misses the point. Both should be part of the discussion since both can be significant pieces in the overall puzzle, the latter most properly as a business practice and the former as an enabling technology set. But neither is The Answer unto itself, so it's not an either/or proposition.
So sayeth me. What sayeth you?
