Compare options using usable output and repair effort.
What appears on screen
Compare options using usable output and repair effort.
0:06 · The idea
Test comparable tasks and record quality failures. Include the time needed to fix them. Unknown repair work prevents a complete savings claim.

0:18 · One useful term
Paired tasks. Corresponding tasks used to compare methods under comparable conditions.
What appears on screen
Corresponding tasks used to compare methods under comparable conditions.
0:27 · A worked example
Method A takes thirty minutes for three passing outputs. B initially looks faster, but one output needs six more minutes of repair. Corrected B effort is twenty-four minutes, with a recorded initial failure.

0:44 · Your turn to think
Can you report usable-output savings while repair time is unknown? Pause and decide before continuing.
What appears on screen
Can you report usable-output savings while repair time is unknown? Pause the video if you need more time.
1:02 · Why this answer works
No. Keep the failure and missing effort visible. A small fixture does not establish unattended reliability.
