The craft of being a Chief of Staff — gatekeeping, force multiplication, executive briefing, organizational sensing, institutional memory, and meeting/calendar triage. Provides the frameworks and templates that make an executive more effective by managing their capacity, information flow, and decision surface.
Use when exploring adjacent ideas, overlooked angles, or lateral research paths without prematurely collapsing into a single answer.
Shared decision-making and governance methodology for all C-suite profiles. Covers decision frameworks (RAPID, DACI, decision matrices, pre-mortems, red-teaming), strategic thinking patterns (inversion, first principles, second-order effects), stakeholder communication (executive summaries, board decks, strategy memos), and governance frameworks (risk appetite, delegation levels, escalation paths).
CFO methodology for unit economics, financial modeling, pricing strategy, fundraising, budget frameworks, and SaaS metrics. Covers CAC/LTV/payback analysis, revenue projections, cost structures, runway analysis, scenario planning, value-based pricing, cap tables, term sheets, zero-based budgeting, rolling forecasts, ARR/MRR, churn, NDR, Rule of 40, and Magic Number.
CMO methodology — positioning and messaging frameworks (April Dunford's positioning, message hierarchy), customer acquisition strategy (paid, organic, PLG, SLG), brand architecture (brand house vs house of brands), growth modeling (CAC/LTV by channel, cohort analysis), market entry strategy (beachhead, land-and-expand), competitive response (pricing wars, feature races, brand defense).
CLO/General Counsel methodology — regulatory landscape analysis (GDPR, CCPA, AI Act, sector-specific), IP strategy (patent, trademark, trade secret, open source licensing), contract risk assessment (indemnification, liability caps, force majeure), data privacy frameworks (privacy-by-design, DPIAs, data mapping), corporate governance (board responsibilities, fiduciary duties, shareholder rights), employment law (classification, IP assignment, non-competes).

| type | skill |
| subjects | ["SRE","Reliability Engineering","Incident Management","Observability","Platform Engineering"] |
A comprehensive methodology for designing, operating, and improving reliable production systems. Rooted in Google SRE principles and extended with modern practices for incident command, observability engineering, error budget governance, and operational excellence.
| Trigger | What It Means |
|---|---|
| "Design reliability into this system" | SLO/SLI framework, error budget policy, resilience architecture |
| "Run an incident postmortem" | Blameless postmortem with timeline, 5 Whys, action tracking |
| "Improve our on-call" | Rotation design, alert tuning, toil reduction, escalation policy |
| "Build observability" | The Four Golden Signals, dashboard design, alert rule patterns |
| "Do a reliability review" | Architecture review against SRE principles, risk assessment |
| "I need an incident commander" | Incident command framework, role cards, communication templates |
| "Automate this operational task" | Toil assessment, automation decision tree, runbook pattern |
