So an "iceberg model" is about trends and patterns over time? That's adding a dimension to the iceberg's ocean and I think the analogy breaks. Usually icebergs are to describe partial occlusion. Also alarming is that in the example for that model QA is something that happens post-release. If so, I expect quality to be a looming iceberg.
