Delfen CTO update

What changed for a decision you are making.
Every Tuesday.

For CTOs, CIOs and board members in organisations where technology carries the business but is not the product. Three to five developments a week, each tied to a decision you make, each with a question you can forward to your team.

In English. Free. Written to be read in four minutes, on a phone.

Every Tuesday

Tied to a decision

Each item says what changed, who it touches, the decision it bears on and what it costs to get wrong.

Ask your team

A question to forward

Every item ends with one question you can send to your team as it stands.

Sourced. Independent.

Independent, no commission

Every item carries its sources. Delfen takes no supplier commission, and says so wherever its own open-source tools are relevant. The update is free.
