Tessl argues software factories must let companies take their accumulated knowledge with them

Tessl's blog post argues that before committing work to a software factory, companies should check whether they can export the knowledge the factory accumulates, not just the code it produces.

The post says engineers' architectural decisions, reviewer corrections, incident lessons and evaluations build up inside the factory over time.

It concludes that an open factory should keep that context, skills and evaluation cases reusable under the customer's control, beyond any one model, agent or supplier.
