Insights · Three recurring columns
Three recurring columns. One buyer-side research desk.
The Cardinal Source publishes three recurring columns, each in a distinct voice for a different reader need. The Analyst Note is the vertical deep-dive. The Field Note is the vertical flyover. The Brief is the technology layer underneath. We publish when the piece clears the sourcing test: useful enough for an IT director to forward before an RFP runs.

The technology layer underneath, explained for buyers.
The vertical deep-dive. The cornerstone research piece.
The vertical flyover. A sharp observation from the field.
Tuesday
The Brief
The technology layer underneath. UCaaS, CCaaS, SD-WAN, security, AI, network — explained for operators making procurement decisions.
Wednesday
The Analyst Note
Vertical deep-dives. The cornerstone research piece — 6 to 12 weeks of work on one industry, then we move to the next.
Thursday
The Field Note
Vertical flyovers. A sharp observation about one industry — what we're seeing in current sourcing engagements that operators in that vertical should know about.
The Brief Tuesdays
The technology layer.
Each Brief takes one technology category — UCaaS, CCaaS, SD-WAN, security, AI, network — and explains it the way a CIO making a procurement decision needs to hear it. Named vendors. Real prices. Maturity by category. Recurring sub-series: The AI Layer.
Where AI actually fits in your tech stack: a layered map
AI is not a category to procure — it is a layer that attaches to whatever you already own. The seven stack layers, what AI does at each one, and the procurement sequence that makes ROI observable in 90 days.
