OKR should be measurable enough for it to be attainable but not too data-driven that it starts to resemble a KPI. While it is encouraged to add figures to your OKR key results, make it simple so that everyone in the organization can easily understand it. OKR that cannot be quantified is vague and just mere wishful thinking. Although OKR does not require as much data as KPIs, it should reflect a measurable quantity that its users can use to gauge their performance.
