During the focus phases, it is generally recommended not to make changes to your OKRs. The OKR framework is designed to provide a clear direction and focus for your business goals, allowing you to measure progress and drive strategy execution effectively. Changing OKRs midway through the quarter may disrupt this process and hinder your ability to track performance accurately. However, it is important to note that if there are significant external factors or unforeseen circumstances that require adjustments to your OKRs, it is advisable to assess and discuss these changes with your team and OKR coach or consultant. By maintaining consistency and alignment with your objectives and key results, you can optimize your business performance management and achieve better results.
