Performance measures how effectively and efficiently we execute our actions. Being a fast rider is a sign of performance.

Output is the tangible product that our actions produce. Getting to Richfield first is the planned output of our three brothers.

Outcome is the impact that our product is expected to have in the world. In our case, the desired outcome was to pick an establishment that will let them thrive in the city.

William rode at top performance and delivered on the planned output, arriving in 2 days, but his good work didn't produced the desired outcome.

In the case of Baldwin, the unexpected circumstances of his journey prevented him to deliver the expected output, despite his good performance. Nevertheless, he managed to achieve the expected outcome.
