Why do you think Clyde wrote a custom cms in the first place? You think he didn't know about Wordpress? In reality he knew but pushed for the custom implementation because it was the best route to improve his skills and increase his power within the company.

The truth is at a typical company Alice isn't going to be rewarded either financially or with better projects.

I wish it was different but if they both worked at the same company Clyde would be the one taking first pick of all the best projects.
