How I work

Write down what good looks like first. The torque curve I drew before anyone asked is what let us move in three months instead of six.

Test to find problems, not to pass. A part that passes every required test can still be the part that fails in the field.

Build it and hand it over. Three handle prototypes from printed and scavenged parts ended a debate faster than any slide.
