If Key Results are the outcomes you want to achieve by the end of a period of time, how you will achieve those outcomes are your projects and tasks. Another name for these are Initiatives.
Capture the results of your Initiatives. Did what you wanted to improve actually improve? What would you ‘keep doing’, ‘start doing’ and ‘stop doing’ next time? Build a knowledge base.
Having a complete picture of the goals, KPIs and Initiatives that have been owned and collaborated on as part of any quarter or year helps employees illustrate their contribution, and managers recognise their value. OKRs are only part of an employees story.
Teams that make their Key Results their Projects and Tasks are probably not using OKRs as you had probably hoped they would. It’s easier and much better to have a clear separation between OKRs, the measurement centric outcomes, and Initiatives, the project orientated inputs.
