Kit, Kit, Kit… First of all, I really should charge you for the bottle of PeptoBismol I had to chug after seeing your site. That is, well, criminal.
I have to disagree with those that suggested a letter. I am a manager, and believe myself to be fair and impartial. The truth is, if you love your job, don’t do the letter. With a letter like that you are saying “Here ma’am, here’s a letter from me that says you’re stupid, btw… I’ve copied other people to let them know how stupid you are.” That, simply, won’t fly. Especially if she is “connected” (pun intended).
You can, however, express your point by building a better solution and camping on it. Just wait for the right opportunity. You can also gather some support in a round-about way: A user survey, for example. Given to all the users of the intranet in order to “Improve and gather experience through the voice of our dear employees”. This will give others the chance to say how much the site “blows” and will not implicate you.
Finally, I have a client I’m dealing with now that has the same skewed reality. He thinks he nows web stuff and he just doesnt. The first thing he did? Well, he had a logo. It was small, ugly, beat up. He said "I’d like to have this in a format that can be easily transferred to billboards, print media, etc… any size, anywhere. So, I spent 20 hours reproducing his image into a vector graphic. Tedious, Tedious work in Illustrator.
What did the client say? It’s too perfect!
Oh well… what can you do? Well, if it is freelance, you can give them back their money and say “Im afraid we’re having problems producing your vision”. We suggest you try these people, or that people… bla bla bla…
If you are an employee of the company and you have bills to pay.
“Wow ma’am. I had no idea anyone could think the way you do”! _______that way they think it is a compliment.
Hang in there, Kit!
