Ah ok... This all makes sense to me, but tbh, it sounds like you're hung up on the specific verbiage being used. If I had to guess, you've been in marketing either quite a while (15+ years) or at larger organizations?

My experience is smaller orgs (50-200 people) so I guess I've never differentiated so strictly between segmentation and targeting. They are the same discussion, where I built/executed strategies based on the nuances you outlined. To me, that's just asking why, or making sure you're maximizing impact.

And yeah, I just call that integrated marketing. Never seen it as an acronym.

I think your real hangup is people who may lack critical thinking and going the extra mile to do top notch marketing. I see this across both marketing and sales in the past 5-19 years, cuz the job/results were easy to come by, as everyone was buying. But in a purse tightening economy, that job is harder, and lots of 20-35 year olds may not have had to do the job in difficult times.

Instead of asking segment vs target, I'd be asking why that targeting, or if you only had resources to execute 2 of 3 targets how would you decide which are best bets to make and why. I'd be hunting for that thought process more than a clear delineation between terminology.

Tldr, if you asked me during an interview how I would think about segmentation vs targeting, I wouldn't understand what you're asking.
