+SIG leads performed a [staffing and gap analysis](https://docs.google.com/document/d/1qeoP6i7GBTVJuJE1AGY5iU9dqmAOxrjqkfNQ2-rBeyI/edit#heading=h.849b7ydpl7ip) for the SIG's projects. We definitely can use more help, and need more part-time/full-time contributors.
+
+### Summary
+
+- **KTLO:** 4 leads at 5%, 2 maintainers at 10% for core, 9-10 maintainers at 5% for 5 subprojects (can have overlap between roles, but need a minimum of 3-4 part-time contributors at 25%)
+- **Feature work:** needs significant ongoing additional investment, minimum of 2-3 FT devs or features will continue to slip
+
+### Details
+
+- **KTLO:** Requires two experienced part-time maintainers at 10% (e.g. 2x4h = 8h/wk) in addition to the SIG leadership (chairs/TLs @ minimum of 2h/wk)
+  - Chairs/TLs currently perform the bulk of this work but even amongst the four of them, **do not** have 8h total weekly allocated
+- **Feature work:** requires significantly more investment from development and review time. 
+  - E.g. Structured logging initiative requires a minimum of 2 FT staff for the duration of feature development from beta -> GA
+  - Additional metric stability classes and graduation: 1PT maintainer at 25% for the duration of feature development
+  - SIG currently owns a number of KEPs stuck in alpha/beta due to lack of dev resources:

+### Subprojects
+
+- Subprojects are currently mature/stable and mainly have KTLO needs
+- kube-state-metrics: 2-3 experienced maintainers at 5%, currently staffed
+- Metrics-server: 2 experienced maintainers at 5%, currently staffed
+- Custom-metrics-apiserver: 1 experienced maintainer at 5%, currently staffed
+- Klog: 2 experienced maintainers at 5%, has **no current staffing**
+- Prometheus-adapter: 2 experienced maintainers at 5%, has **no current staffing**
