I think the critical piece to determining whether or not use Event Sourcing is, as you said, if the history of the aggregate provides a strategic advantage. Often times this is just not the case. Sometimes a key, value store will suffice or even an Active Record approach works. Keep your options open and choose the best tool for the job.

“That said, DDD is an effective approach when the system you’re building is part of the strategic advantage of the business.” What kind of system wouldn’t be part of the strategic advantage of a business? Why would a business embark upon a project that doesn’t contribute toward the overall strategy?You need a better reason to use DDD than just saying “the system is part of the overall strategy”.

I don’t think many developers are aware of Event Sourcing. I had a discussion with a product owner where he described what he wanted in his ideal system. To paraphrase what he said it was… ”I want the system to record in the Audit logs exactly which fields have been changed on a record, but in a meaningful easy to understand way”. All development solutions for this in the past had involved complex solutions that didn’t really provide the meaningful results.(triggers, temporal tables, field-level transaction logs, etc)
When we started talking event sourcing, the product owner caught on right away and said “Yes! That’s exactly what I want”, but it took some time for developers to understand the concept.
Sometimes the reason why the business isn’t investing is simply because they aren’t aware .

Excellent Post… Event Sourcing can be a very powerful strategy if implemented properly.

I am surprised there aren’t any Enterprise-y systems yet that capture The Event Store(tm) as a primary source of data.

Apart from that, I think the rule still holds true that which you do not capture is not available. Hence, your system will rather quickly have to deal with versioning requirements, if you e.g. realize that the geo-location of placed orders is a critical information.
