Pros
I've been with Kaiser for 13 years working in the IT field. The people on the business and medical side are great to work with. They are flexible on hours and allow us to work from home once a week. I feel generally apprised of what is going on in the company and benefited from a positive outside view of the healthcare Kaiser provides.
Cons
The technology is severely outdated. The bureaucracy is about the worst I have seen as far as getting things done, getting software upgrades, network connectivity, utilizing decent hardware, and going to tablets and handhelds. IT management is completely disjointed from healthcare delivery. IT services are much more interested in filling out the paperwork and going through the extensive motions than they are of delivering a product or service. If you like filling out forms, waiting in endless lines for approval, and OK with the status quo, this is the place for you.
