Framework/CMS suggestions for enterprise website & intranet (I've got to convince the president its solid!)
"They want me to use a framework/set of languages/technologies that I can prove to them are "stable, enterprise-ready technologies with a proven track record.""
There's no proof of those features.  None.
Is there some incumbent technology that they want you to use?  If so, you might be swimming upstream.

If you're fighting for your preferred technology, you probably can't win their hearts and minds without a serious proof of concept or pilot project or something.
If they're willing to listen, they'd be more willing to listen if you had a demo that showed how rock-solid your preferred approach is.

if there is no incumbent, then they're just wringing their hands.  In this case, you'll need some evidence they actually believe -- a pilot project or a proof of concept.
There's no Proof in this industry.  For every technology you can find a proponent and an opponent.  Even crap technology has proponents.  Forget proof. 
Just pick something that you can use very rapidly.  Get something up and running so quickly, with such high quality that you're obviously right and the rest of your opinions must be equally right.
For this reason, flexibility has no value.  Go with Django and get something to run ASAP.
Dear stack overflow community,
I've been given the task of overhauling a couple of websites for a large corporation I'm working for, as well as developing an internal intranet site for content management and document storage within the organization.
My "problem" is this: They want me to use a framework/set of languages/technologies that I can prove to them are "stable, enterprise-ready technologies with a proven track record."
The spec's "big picture" really isn't too complicated: Implement an enterprise-class CMS for management of each division's web pages that deal mostly with product information and documentation (i.e. a simpler version of www.linksys.com).
As an open-source programmer, I'd like to use Python with TurboGears and build it from scratch, but I can't really find a way to prove to the president that TurboGears has a huge enterprise track record. Zope seems to have a lot of enterprise usage, but it looks a bit bloated to me. Django could be an option, but doesn't seem as flexible as TurboGears.
I'd rather not use PHP, but Drupal has a very nice resume with the "right" names under it (AOL, Sony, MTV); plus it could save me building many of the CMS components from scratch.
Rails might be another option, but I'm not too familiar with it (and as a Python/PHP programmer, Ruby's syntax drives me crazy).
What would the S.O. community suggest for a project like this? I'm sure many of you have faced the same dilemma. What ended up working/not working for you? As I said before, my first choice would be Python, second would be PHP, third would be Rails.
Thank you,
Seth
