The praise in this thread is clearly from people who never had anything to do with the modern Swiss Post.
I had to setup a mail "hold" order (in Switzerland you have to pay an extra fee and make a request to not deliver mail when you leave for a few weeks) and I found the UI to be very confusing.
I think the design of the site could be improved, here is what annoys me the most:
* The "clickable" button color being so close to the "disabled" color that it's very hard to distinguish when they are not next to each other (as most of the time) and very confusing when you try to click on a seemingly active button and nothing happens
* Calendar widgets letting you select every date, but after selecting the date, you get an error message
* communications in German despite the whole process being in French and the destination address being in a 100% French speaking canton
* downright bad French translation (hi from the 25% of the Swiss population) eg: "Reprendre" is *not* a valid button name, maybe use "selectionner"
* ending into a redirect loop when going back during the check-in step
The UI feels broken. There is a lot of "strange" space, or button layouts accidentally ending up on two rows eg: the login nag dialog (I could reproduce it on Firefox and Chrome).
It felt like a miracle when I managed to complete the process after about 1 hour (process that technically only requires my name, address and payment coordinates)
I'm used to computers acting up and generally bad software (hell, I use Linux), so I could handle it, but my mom says she has trouble with the website as well.
If you need more details, or a generous Romand QA tester, don't hesitate to contact me (domain of email address in my user profile).
I feel that good software is important, especially for a state-run monopoly. Because it's always the most marginalized people that end up eating up the hidden costs of rushed-up software.
