I say both. Take today for example. I went to the hospital to make rounds. Back in the dark ages (last year), I would go to the ward, pull patient charts, grab the paper printouts of the labs and swing by X-ray to glean information. Pretty easy, low stress. This morning I logged on the computer to get the labs — not so fast. The computer told me my password was invalid. I tried again. It then told me I was locked out. Yesterday it was okay. What happened to invalidate me overnight? I called IT for help. First they told me to do three things. No go. Then they told me they would call back.
