A rule for user interaction: keep debugging information out of error messages

Sunday, February 10th, 2008

Yet another example of bad web programming. I was researching the subject of cancer and followed a link on a government site that gets me to this page:

Error message on government site: debugging information should be kept off of live sites

I think its fine to print debugging information to the screen when a website is under development, but on a live site, I think the error messages should try to be more helpful. Perhaps the error message can suggest the average speed it takes the site’s sysadmins to fix problems of this time. Or the error message can suggest that the visitor go get the page out of the Google cache. Even the cutesy error message that Stikipad used was more reassuring than this.

Netflix error: why allow a date that is not allowed?

Sunday, February 10th, 2008

Back on September 24th, I decided to put my Netflix account on hold. I knew I was facing a stretch of time when I was going to be too busy to watch movies. Apparently Netflix only allows you to put your account on hold for 90 days. Nevertheless, the form that I was presented with allowed me to choose any date in December, so I chose December 31st, as you can see here:

Netflix error: the form that allows forbidden dates to be choosen

Upon submitting the form, I got the following error message:

Netflix error: why do they allow users to choose dates that are in fact not allowed by their policies?

This is, of course, an example of bad user interface design. They should not allow me to choose a date which they themselves forbid. It is confusing that their form should offer a date which is, in fact, not allowed.

What designers do

Friday, November 30th, 2007

The framework I wrote auto-generates forms based on the definition of a table in the database. These forms are usually quite ugly. The advantage of these auto-generated forms is that they speed the initial set up of a site - I simply define some database tables, based on what the client has told me they want, and the framework auto-generates the form.

On the TSR site, we are still cleaning up the rough edges. Laura Denyes, the lead designer on this site,  is transforming the rough and ugly forms. After enhancing the clarity and improving the use of space, we hope to leave the user with a better experience. You can see Laura’s work in this before and after image:

Sprint PCS is even more broken than before, thanks to its merger with Nextel

Monday, September 24th, 2007

I’ve written before about the error messages I’ve encountered on the Sprint PCS website. I’ve been unable to log into the Sprint PCS website this month - I get some bizzare error messages instead.

Today I figured I’d try to use my phone to pay the bill. I hit “*2″ which dialed customer service for me. I reached an automated voicemail system. It asked me to type in my phone number, so it could look up my account information. I did so. It then told me that I owed Sprint $513. I was stunned. By my calculations, I owe something like $200. I pay about $97 a month, and I owe last month and this month. I’m not sure how the amount doubled.

Eventually, the automated system gave me the option to talk to someone. I pressed the button.

A pleasant, helpful woman got on the line and asked for my telephone number, so she could look up my account information. I gave her the number and she said they had no account information for me. I explained that I’d had this account with Sprint since March of 2001. She explained that she worked for Nextel, she didn’t have account info for Sprint customers (the two companies are merging).

This is puzzling. If Nextel doesn’t have any of my account information, then why should my phone auto-dial Nextel when I press the buttons for customer service? Also, if Nextel has no information about me, how did the automated system tell me that I owed $513?

What happened next is also puzzling. I said, “Okay, can you transfer me to Sprint Customer Service?” She said she could not transfer me there. She could, however, give me the phone number. Why can’t the phone company transfer me to the number they want me to go to? I find that confusing.

I dialed the number she gave me.
Sprint PCS also had an automated system. It asked me to type in my telephone number, so it could look up my account information. I typed in my telephone number. It said there was no account with that number, and it suggested I type it again. I assumed I’d mis-typed it, so I tried it again, carefully. Again, the automated voice system told me that there was no account with that number. I didn’t know what else to do, so I typed in the number a 3rd time. Again it told me there was no such telephone number.

I couldn’t think of what to do then. The automated voice system did not give me any other option. It kept asking me to type in my telephone number. It asked me 4 more times, and then, when I did nothing, it hung up on me. It never offered to transfer me to a human operator, who might have been able to resolve the situation.

I’ve had this account for 6 and half years. Right now, I seem to be completely locked out of it. The computer at Sprint PCS claims my account doesn’t exist. At Nextel, the computer says I owe the incredible amount of $513, and then the operator says she has no access to my account information because it is over at Sprint.

I don’t need to know many of the details to tell that the merger of Sprint and Nextel databases is going badly. If I had stock, I’d sell it. This is the worst customer service experience I’ve had in many years.

SprintPCS has a broken website (Updated)

Friday, September 14th, 2007

Yet another story about a badly programmed website, with really bad error messages.

I went to pay my monthly cell phone bill. Just last month, SprintPCS instituted a new policy, requiring stricter passwords with more letters and numbers in them. So I was forced to change my password. Perhaps I was also in a hurry, as I did not write it down in the usual place.

Today, unable to remember the new password, I clicked the link they offer for “Forgot your password?” I came to the screen you see in the first image.

this is the form on SprintPcs.com where I request my password

I typed in my “username”, which is simply my telephone number. When I hit the submit button, I got, in response, a blank white page with the text “Error: 500″. That’s it. Nothing else. Just that text on a blank white page. You can see it in this second image:

This is the error message I got from SprintPCS. Not very helpful, is it?
I offer this anecodote as one more small piece of evidence for the case that most web sites are horribly programmed and poorly tested. I don’t mean to pick on SprintPCS, since there are many sites that are just as bad, but this just happens to be the broken website that I interacted with today.

Mind you, the above incident happened this morning, around 11 AM, and now it is 11 PM. I just went back to get screenshots. Twelve hours later, the problem is still there.

I sent SprintPCS an email about this. I have not yet heard back from them. I’ll update this post if I do hear from them.

UPDATE: wonderful response time. I just got this, on the 17th. The irony:

“Where our customers come first!”

Refer someone to Sprint and get $25.

So after 3 days, they send me an email in which they promise to contact me within 3 days. Then they close with “Where our customers come first!” Hate to think how we’d be treated if we came second.

Usability is a single piece of an experience puzzle

Monday, July 23rd, 2007

A very nice point by Robert Hoekman:

We hold up usability as laudable because, sadly, most companies still have serious trouble putting their pants on correctly when it comes to usability. They need the gold stars.

Anyone in the interaction design or usability profession worth his salt knows that usability is a single piece of a very large “experience puzzle”. You need a strong value proposition to get users in the first place. You need a compelling product or service. You need good customer service when things go wrong. You need marketing prowess. You need something that makes you different, and better, than everyone else in your space.

For a product or service to be great, you need all these things. But you also need a usable touchpoint. A strong value proposition gets people interested in your product, but once you have their attention, a high level of usability helps motivate people to keep using it. A low level of usability deters people from using your product.
