When it comes to product documentation—the information that explains how to use a product—many people prefer to do without. The mantra “when all else fails, read the documentation” has proven true in many of the usability studies we have conducted over the years. Even in cases where we were testing the documentation!
Users have come to expect that products should be designed for ease of use, so why bother to read the documentation? But in some cases, the documentation gives you essential information on how the product works.
Case in point: the Dirt Devil Cordless hand vac
When I purchased one recently—the 15.6 volt “Gator” model, I was already a happy Dirt Devil customer with two Dirt Devil cordless hand vacs in my home. This latest one was for my husband’s office. Having prior experience with these hand vacs already, I didn’t need to read the documentation to know how they work. You take it out of the box, plug it into an outlet and wait 24 hours for it to attain a full charge. The red indicator light on the top side of the vac tells me it is charging, and when fully charged, it stays on to let me know that it is still plugged into an outlet.
That’s how the other two Dirt Devil vacs work, and that’s what I expected from this one. But this one was different. For some reason, the red indicator light did not stay on.
So, I got out the instructions and read the part about charging the unit. The last sentence below is the important one.
SAVE THESE INSTRUCTIONS
IMPORTANT: BEFORE FIRST USE, CHARGE YOUR UNIT FOR AT LEAST 24 HOURS.
- Power switch must be in the OFF position.
- Plug charger into standard outlet. Plug barrel adaptor into charging port (A).
- The indicator light will come on to indicate that the appliance is charging. The light will not change when the unit is charged.
When all else fails, call customer service
Even less desirable than reading the product documentation, for many, is calling customer service. We’ve done usability testing of IVR (interactive voice response) systems, so we know from users how much they dread using a company’s voice prompt system (press 1 if you are a new customer, press 2 if you are inquiring about an order, etc. etc.). Most users want to get directly to a human, and savvy ones know that if they keep pressing 0 they may get directly into the queue for customer service.
Some companies have tried to address bad user experience with their IVR systems by adding helpful features to let customers know how long the expected wait will be and to allow customers to provide a call back number, which, supposedly, allows the customer to keep his or her place in the queue without having to stay on hold and listen to elevator music.
This is helpful when it works, but not when it doesn’t. Having provided my call-back number a few times, I have experienced a level of unreliability in actually getting a call back that makes me question the process.
But in the case of my call to customer service for Dirt Devil, they didn’t provide an estimated wait time, so I took a chance and left my call back number. And didn’t get a call back.
Now, the quality of my user experience was suffering for two reasons:
- I wasn’t confident that the product was functioning properly
- Customer service did not call me back when I left my callback number
Determined to get an answer to the problem of the light going out on the hand vac, I called customer service again and waited it out to get a real customer service representative.
Customer service has the answer
I explained my concern about the hand vac’s operation to the customer service representative. He listened. Then he said—“We get this question all the time.”
He explained: “What happened is . . . engineering redesigned the hand vac so that the light goes OFF when the hand vac is fully charged. But they didn’t change the documentation. So, when people call us, I explain that the product works as designed.”
I was amazed that the company had gone through a redesign of the product—likely to make it more user friendly—so that you would know when it was fully charged and ready to use. . . but they hadn’t changed the documentation.
Not even on their website. Not even as a sticker on the box or on the front of the instructions.
Instead, people like you and me will do one of the following things:
- Return the product because they think it’s defective—resulting in lost sales, lost reputation
- Go to the website for an update on the documentation—nothing there except a PDF of the faulty documentation
- Call customer service—resulting in wasted time for the customer; big expense for the company
- Nothing—some people will not notice that there’s a difference in the instructions and the actions of the product
I’m wondering if Dirt Devil is counting on people doing nothing.
One word in one sentence could make all the difference
If they had removed one word—not—in the sentence: “the light will not change when the unit is charged,” they would have fixed the problem.
User experience is more than designing a great product. It’s considering the needs of the user at all touch points—in this case, opening the box and, if the customer reads the documentation, having the confidence that it guides them through a good experience.
