Dave clark brought this from Amazon. At Amazon they call it "STLs" or single threaded leadership. Basically you assign one director/vp/etc. to the business, and they are responsible for PnL/success.

It isn't that you do one thing at a time as an entire company, but your org is focused on one thing. For example, maybe there is a director who runs an org in charge of international freight forwarding.

I'm not really sure how things are organized at other large companies as Amazon was my only experience into mega corp work.

"A single-threaded leader is a leader who is 100% dedicated and accountable to a specific product, such as your mobile application, customer account, or the search capability in your e-commerce store. The single-threaded leader is responsible for turning strategy into real results, and they are empowered to do so."

"They are only able to do one thing at a time?"

To be fair, many new businesses cannot do one thing at a time, so maybe singular focus is a good thing at this stage...

Narrowing focus is often a good thing for companies.

Probably removing redundancy in the business flow process path?
