Models and Modularization with Alistair Cockburn

At the recent Software Architecture Gathering, Eberhard gave a
talk on models, modularization, and Bounded Contexts, while
Alistair explored similar themes in conversations with attendees.
In this episode, the two come together to discuss the key
concepts behind these topics, compare their perspectives, and
answer questions from the audience.
Quote from Parnas

Here is the quote from Parnas’ paper that Alistair referred to:


“We propose instead that one begins with a list of difficult
design decisions or design decisions which are likely to change.
Each module is then designed to hide such a decision from the
others.”
