The deal was that who ever did the intervention had to stay for the monitoring and the customer preferred a vendor resource to perform the install. We all sat down to consider our response to the customer demands and came up with the following escape tactics...
- The team takes ownership of the whole operation, sliding different folk on to the critical terminal for each stage.
- Install the patch and at the next customer meeting have a few rounds of "He installed the patch." .. "No I didn't he installed the patch" Rinse and repeat.
- "Sorry I sipped on a banana skin, hit the return key and installed the patch by mistake."
- Explain that Auto update popped up dialog box, and no one was available to click "Install later".
- Have a person in a Santa Claus suit install the patch telling the customer that he is free until christmas for what ever you want to pay him to do.
- Try the Spartacus defence, All stand up and say "I installed the patch.","No I installed the patch."
Turns out that the customer deferred the whole install leaving them vulnerable to various crashes and hangs etc. I suspect that by the time the customer does get round to have the patch installed it will have been superseded by a later version.
