  • Clayton Silva thinks this is interesting:

key result is a quantitative statement that measures the achievement of a given objective. If the objective asks, “What do we want to do?” the key result asks, “How will we know if we've met our objective?” In our previous definition, some may quibble with the use of the word quantitative, arguing that if a key result measures achievement, then by its very nature it's quantitative.
