I've been creating blog posts from time to time over several years now, but recently I've been privileged to be asked to provide articles for The Business Bulletin.
Here are links to those magazine editions:
Edition 24 - Business Bulletin Magazine (Spotlight, page 30)
Edition 22 - Business Bulletin Magazine (page 38)
Edition 19 - Business Bulletin Magazine (page 30)
Edition 15 - Business Bulletin Magazine (page 14)
LinkedIn articles
I occasionally also write articles on LinkedIn.
Why it has to be agile. Sort of.
And finally of course, I maintain my own blog with articles about software development and the business of software development.
