If you want to "disrupt" housing, only one KPI matters.
Cost. It's as simple as that. To solve for that, only logistics matter -- logistics of materials & people. Secondly, processes/systems/platforms built for scale.
You don't first focus on the "product" ...
You focus on logistics, how those logistics scale, and only then, the product. In my opinion, this is why every company that tried to "industrialize" consrtuction failed and continues to fail. Only then can you focus on the product because it is highly tied to 1) and 2) ... and then, there are other parameters you have to stay within (e.g., regulatory, supply chain availability, on-site assembly without skilled labor (which drives the cost down the most), etc.).
Proof is in the pudding. Cost, and more importantly, repeatable quality at that cost.
