Jurgen Desmet invited me for a coffee talk about code ownership and Conway’s Law on his youtube channel.
The description accompanying the video
Sharing experiences, practices, and methods related to shared code ownership and the relation to organisational structures. Or how much should Conway’s law be taken into account.
When simplifying organisational structures one will go against the basics of Conway’s law and will need to lean on the abilities to have shared code ownership. As such a perfect topic to explore more in-depth with one of my Technical mentors in the field: Nelis Boucké.
We’ll address dynamics, mandates, architectures, freedom, going from A to B from an experience point of view. Giving examples on how it has been dealt with, no theories or strong statements here. Pure experience samples.
