So we're doing interoperability testing of “Project: Sippy-Cup” with two companies so far, Company-A and Company-E. Basically, it's testing to see if we accept their requests and they accept our replies and we're all on the same page as far as interpreting the results and what have you. And today isn't the first day we've done such testing—this is about the third or fourth time so far.
“Those responses are odd.”
“No wonder—you aren't sending the right phone numbers!”
“But we're sending 555-555-9901!”
“What? I thought it was 555-555-0001!”
“That's so yesterday! Didn't you get the memo outlining the new numbers to use?”
“But we're using 555-555-9901.”
“Okay, let me make that change … okay, we're now using 555-555-9901.”
“Didn't you get the memo? We're using 555-555-4492.”
“But you were just—”
“No wait! New memo came in! Can you change the number of 555-555-2234?”
“Probably not before you change it again, but I can try … ”
And each time, the phone numbers used for testing have changed. Every. Single. Time. It seems as if Company-A and Company-E are incapable of using the same phone numbers for testing for more than 24 hours.
