Reason 1. Defocus.
A lot can be accomplished in a year, so it's no surprise that a company might have many vectors of desired changes. In my recent client case, there were 6 directions of strategic changes. And there can be more.
What happens if all this goes into annual OKRs and this is the only guideline for the teams? Firstly, an enormous workload - when you don't know what to grab onto, too many priorities mean there are no priorities at all. Resources are overloaded, teams can burn out, and the result is not noticeable - leading to disappointment in the OKR system itself (although the system prescribes otherwise).
Also, when the result is expected in a year, it inadvertently provokes procrastination, and the team first takes on urgent, even if not so strategically important tasks - because there is still time.
How to fix it?
Yes, annual goals can be formulated in the format of OKRs.
But after that, a second planning session should be held and OKRs set for a shorter period - from 1 to 4 months. And determine which 1-3 directions should become the true priority for this period.
When the period ends, analyze the results and make a balanced decision - which direction to continue in the format of OKRs for the next period, which can already be transferred to Run activity, because the necessary level has been reached and clarity obtained, and which new OKRs to take.
