At Google and after, I have been fortunate to lead or co-lead the Goal Setting Process - from the company level to both large and small teams. Google follows an OKR process where OKR stands for Objectives and Key Results. Objectives are what you want to do. Key Results are how you will measure them.  

In addition, each goal must pass the SMART test.

For reference, Measure What Matters is the guidebook of OKR planning.

If you or your team needs help with goal-setting sessions based on OKRs and Smart Goals, please get in touch.
