Not sure about what you're saying here. In no way did Martha bring vision, set direction (see note below), or provide motivation. She sat and read the code for a while until she found the problem. Without any more detail, it seems likely enough that Arnie was setting the vision/direction and providing motivation. They just didn't reach their goal before (relatively uninvolved) Martha figured things out.

Not trying to devalue Martha's contribution. I love the Marthas in my workplace. But, very often, they're not leaders. They're the people leaders know to turn to in times of crisis. They're extraordinarily valuable, and should be compensated/lauded accordingly, but that doesn't mean they're the leaders. Nor, in my experience, do they always wish to be.

Note: Martha did, of course, "set the direction" at the end of the meeting, when she'd found the bug. But I take direction-setting to generally be an event prior to the activity (in this case, debugging). Martha did not do that.
