After the previous post’s long sequence of service design failures, here’s one little thing that should be easy to get right, and which causes incredible frustration at exactly the wrong moment.
When buying a train ticket online in the UK, in advance, you can choose to collect the ticket from a machine at the train station. You receive an email containing all the relevant details.
When you get to the station the machine offers this screen:
Please enter your booking reference:
You check the email you’ve kept handy on your phone and look for the “booking reference”:
There it is, near the bottom:
Your booking reference is 2106902679.
You type it in to the machine, although the input field is the wrong length, which is odd.
The machine rejects your booking reference.
You try again, because you must, but no joy.
In desperation you scroll through the rest of the email because you don’t know what else to do and your train leaves in a few minutes:
Hmm. What’s this?
Collection reference: R2T4KB9C
But the screen wants the “booking reference”, which was the first number.
It’s worth a try…
Ah, this “collection reference” is the right length…
And, yes, the machine starts printing your tickets!
So, what the collection machine calls a “booking reference”, the email calls a “collection reference” or (in the subject line) a “booking confirmation”. And the email contains a “booking reference” number which appears to have no purpose, even though it’s the first reference in the body of the email.
When starting a project, and throughout its life, it’s important to ensure everyone involved calls things by the same names. I’m guessing that in this case different teams, or even companies, built the software that sends the emails and the software that runs the collection machines. Due to a mismatch of internal vocabularies the single piece of information the user needs at the most crucial part of the process has been muddled.
It’s probably a nightmare of laborious and expensive change request processes to fix this simple piece of wording, which has already been wrong for months, if not years. But that’s another issue.
