 ## 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)
 
-   -
-   -
-   -
+   - Code contributors and reviewers
+   - Issue triage/response
+   - Whilst there are no areas with explicitly 2 or few owners, there are a number of areas where we have this few subject matter experts, acting as a significant bottleneck for significant changes
 
 2. What metrics/community health stats does your group care about and/or measure?
 
-   -
-   -
-   -
+   - Currently lacking in measurement of community health stats
+   - Care about growing number of contributors
+   - Would like to begin measuring time to merge of community PRs
 
 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?
 
-   -
+   - Not currently
 
 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]?
 
-   -
+   - N/A
 
 5. Does the group have contributors from multiple companies/affiliations?
 
-   -
+   - Yes - though the core approvers are almost all from a single company.
 
 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?
 
-   -
-   -
+   - Increased support for some cloud provider implementations for the Cluster Autoscaler
+   - Responding to issues - the SIG currently lacks the capacity to respond to all issues raised
