Objectives are the goals that a company wants to achieve in a certain period of time. Key Results are the specific tasks that need to be completed in order to reach those goals. The most common mistake is not defining clear objectives and key results for each objective. This makes it difficult for employees to know what they should be doing on a daily basis and how their work contributes to achieving the company’s goal. Another common mistake is not having specific deadlines for key results, which makes it difficult for employees to know when they should finish their tasks by and whether or not they will be able to complete them on time.
