I have been using this term for quite a long time (at least 5 years or more). I thought I should probably put it down in writing officially so that I have some claim to it in the future. I have found 1 company on the internet that uses this term but not sure of others. Just in case...also I am not sure if you can Trademark, Service Mark or Copyright a job title, but what the heck..
I came up with this term in relationship to the work I do. Many organizations have CIOs, CFOs, COOs, CEOs, etc. But I have never seen someone called a Chief Service Officer. Yet in this day and age when many companies are shifting to being service providers, wouldn't it make sense to have someone in charge of providing, managing and guiding those services? I thought so! So here it for all posterity!
