The type of FOD you will typically find in manufacturing mainly consists of metal shavings, metal chips, pieces of wire, string tie, safety wire, misc. small parts such as washers, rivets, nuts, etc. It's just poor housekeeping practices by the mechanics and QA, plain and simple. It is not a new concept by any means.
Tools can be a part of that equation though if there are poor tool control policies/enforcement. I believe the mechanics at Boeing use their own tools and are entrusted to properly inventory their tools prior to and after work to ensure all are accounted for.
We had the same problem years ago with Lockheed, but ultimately convinced them to move to company owned CTK's (Composite Tool Kits) which had a lot more control. 2 people inventory before and after work. The amount of tool related FOD fell dramatically.
