“Dear Customer, the truth about IT projects” was originally published in The Agile Journal way back in 2012. Unfortunately the essay has stood the test of time and is still regularly re-discovered online.
A couple of weeks ago I recorded an audio version of Dear Customer which I have now posted online. You can find links to the original publication and of a PDF of the essay at the same site.
O, and the essay forms the prologue to my Xanpan book, but newsletter subscribers probably know that because they downloaded a free copy of Xanpan when they subscribed!
