1. What work did the SIG do this year that should be highlighted?
-
-
-
- We're working closely with [WG Batch](https://git.k8s.io/community/wg-batch/README.md) towards improving batch workloads for use in HPC, AI/ML and data analytics workflows.
- [Mentoring cohort](https://github.com/kubernetes/community/issues/6665) which allowed us to grow our reviewers' list.
2. What initiatives are you working on that aren't being tracked in KEPs?
-
-
-
- None.

## Project health
1. What areas and/or subprojects does your group need the most help with?
Any areas with 2 or fewer OWNERs? (link to more details)
-
-
-
- The [mentoring cohort](https://github.com/kubernetes/community/issues/6665) we've run in 2022 attracted a few new members, but we still need more.
2. What metrics/community health stats does your group care about and/or measure?
-
-
-
- [Open untriaged issues and PRs](https://github.com/kubernetes/kubernetes/issues?q=is%3Aopen+is%3Aissue+label%3Aneeds-triage+label%3Asig%2Fapps)
3. Does your [CONTRIBUTING.md] help **new** contributors engage with your group specifically by pointing
to activities or programs that provide useful context or allow easy participation?
-
- It's up-to-date.
4. If your group has special training, requirements for reviewers/approvers, or processes beyond the general [contributor guide],
does your [CONTRIBUTING.md] document those to help **existing** contributors grow throughout the [contributor ladder]?
-
- No additional training than the recent mentoring cohort is planned, yet.
5. Does the group have contributors from multiple companies/affiliations?
-
- [13 companies](https://k8s.devstats.cncf.io/d/8/company-statistics-by-repository-group?orgId=1&var-period=y&var-metric=contributions&var-repogroup_name=SIG%20Apps&var-repo_name=kubernetes%2Fkubernetes&var-companies=All&from=1609455600000&to=1639350000000) contributed code in 2022.
6. Are there ways end users/companies can contribute that they currently are not?
If one of those ways is more full time support, what would they work on and why?
-
-
- Increase the test coverage for all controllers, is probably the best way to help and start contributing to sig-apps owned controllers.
This also nicely fits into the on-going effort of [increasing the project reliability](https://groups.google.com/g/kubernetes-sig-release/c/P5gFtnjXDqI/m/lVVZ40w2AAAJ).
