Measure the Throughput Instead of the Keystrokes
In , an industrial engineer named Frank Gilbreth studied the movements of bricklayers. He measured the number of motions required to lay a single brick. He reduced these motions from eighteen to five.
The efficiency of the individual worker increased by 320 percent. However, the completion date of the building projects remained largely unchanged. The site became a graveyard of perfectly laid bricks that waited for mortar that had not yet arrived.
Efficiency at the local level (red bricks) creates piles of work that cannot be completed due to missing system components (mortar).
The speed of the bricklayer was not the speed of the building. The individual was faster, but the system remained slow.
The Dashboard Delusion
Tom sits in a windowless conference room at on a Tuesday. He watches a screen share from a software vendor. The account executive points to a graph showing seat adoption.
The graph shows that ninety-four percent of his engineers use the AI tool every day. This number represents a successful rollout in the eyes of the vendor. The vendor is happy because the licenses are being used. High usage suggests that the renewal of the contract is likely.
Tom looks at his second monitor. He views his own DORA metrics for the
