How frequently are reviews of change proposals sent to non-pilot units for comment resolution matrix?

Change proposals are reviewed rather biennially, which means every two years. This timeframe allows for a comprehensive assessment of the proposals and provides adequate opportunity for non-pilot units to gather insights, conduct necessary evaluations, and offer informed feedback. Such a systematic review process ensures that any changes made are well thought out and take into account the operational effectiveness from a broader perspective involving various units across the organization.

The other options do not align with the established frequency for these reviews; they suggest much more regular intervals, which could lead to analysis fatigue and less meaningful feedback as units may not have enough time to adequately assess and formulate thoughtful responses. Thus, the biennial review period strikes an effective balance between being responsive to changes and allowing enough time for thorough analysis by involved units.
