# The Goal – Outline - Narrative framing - Follows fictional plant manager Alex Rogo trying to save a factory and his marriage. [page:1, {ts:1604}] - Learns via Socratic lessons from his former physics professor. [page:1, {ts:1621}] - Core theory - Every system has a bottleneck (slowest step) that constrains overall output. [page:1, {ts:1570}] - Effort is most valuable when applied at the bottleneck; effort elsewhere often wasted. [page:1, {ts:1698}] - Illustrative examples - Chicken coop line: move one worker to bottleneck → triple output. [page:1, {ts:1539}][page:1, {ts:1586}] - Boy Scout hike: redistribute backpack weight from Herbie to faster kids. [page:1, {ts:1621}][page:1, {ts:1648}] - Condensation of the theory - Goldratt claims he can reduce theory of constraints to one word: focus. [page:1, {ts:1679}] - Book is hugely influential (10M copies, required reading at Amazon). [page:1, {ts:1663}]
