This site is free for everyone to read, and I hope it’s worth at least twice that. I plan to keep this material free. However, if you appreciate what I do, you might wish to support my work. Here are some ideas:

I’ve turned off the Ko-Fi thing and while other links might find me, if you want to give away the cost of a coffee or a BMW, please give it to a worthy cause. Well, if a BMW, check with me, I might reconsider … otherwise …

Please consider purchasing a copy, or a few hundred copies, of my book The Nature of Software Development. And please, if you can, purchase from the Pragmatic Bookshelf. Why? Because the book is deeply discounted on Amazon and other resellers, and I get a only fraction of the royalty I get from Prag. Pardon my venality, but this is the Support page, after all. Unfortunately, Prag no longer stocks the paper version, but you can get it from Amazon. The many pictures are in color, so paper, or a color reader, are recommended.

For direct ongoing chats with me and other people interested in Agile Software Development, please consider subscribing to our Slack group at The monthly fee is low, and if you can’t afford it, get in touch and we’ll see what we can do. The group discusses a wide range of Agile-related topics, including conferences, agile “transformations”, scaling, coaching, and more.

Or, hey, drop me a note saying thanks, or toot at me. It’s all good.

Seriously, though, if you value what I do and would like to give back, one of the methods above may work for you, and I’ll certainly be grateful. Thanks!
