A comment more useful than an entire article. Personally, I try to judge performance using standards and goals.
To me, standards are a clear, agreed-upon baseline that every member of the team must meet. They're not what we preach, they're what we tolerate. It is intolerable if a member of the team doesn't meet a standard.
Goals on the other hand, are what we hope for; they cannot be "lived up to", coerced on an individual or forced from the outside. If a member of the team can't achieve a goal, then they need differents goals.
I set the standards to be low and universal, while the goals are high and person-specific[1]. I'm thinking objectives could be thought of as "parts of standards that must be met at a later point in time but now now"[2]. But I'm still figuring it out. I think material about education is relevant, and helps to avoid easy, versatile, and deceiving thought-terminating cliches like "expectations".
