# 2023 Annual Report: SIG Scheduling

## Current initiatives and Project Health

1. What work did the SIG do this year that should be highlighted?

<!--
   Some example items that might be worth highlighting:
   - Major KEP advancement
   - Important initiatives that aren't tracked via KEPs
   - Paying down significant tech debt
   - Governance and leadership changes
-->

2. Are there any areas and/or subprojects that your group needs help with (e.g. fewer than 2 active OWNERS)?

<!--
   Note: This list is generated from the KEP metadata in kubernetes/enhancements repository.
      If you find any discrepancy in the generated list here, please check the KEP metadata.
      Please raise an issue in kubernetes/community, if the KEP metadata is correct but the generated list is incorrect.
-->

3. Did you have community-wide updates in 2023 (e.g. KubeCon talks)?

<!--
  Examples include links to email, slides, or recordings.
