I blog the top ideas from each book I read (link in bio) and form book clubs at work. We have an Engineering team book club, Product Design book club, and a company-wide book club.
We meet for one hour over lunch. In advance, the book club leader assigns about 30 pages to read. It's important that the page volume feels substantial, but also enough that people can complete the reading 30min before the meeting.
As a leader, I purchased the books for everyone using the company credit card and make it clear that it's your book to keep - so take notes, highlight, whatever you want.
The leader facilitates the conversation. Some leaders will post questions in advance on Slack. Other leaders will develop questions on the fly based on the direction of the conversation.
In the best product design and engineering books clubs, people reference specific passages and quotes which spark conversation about implementation within your own shared work.
