Customer Feedback Surveys Could Be Considered Harmful (easydns.org) 196

Longtime Slashdot reader Stunt Pope writes: Customer Feedback surveys are now near-ubiquitous, subjecting us all to near-Black Mirror-esque pursuit to "rate your experience" for everything from going to the bank to ordering a pizza. Thanks to The Curse of Goodhart's Law, all of these surveys are beyond useless and even damaging. Mark Jeftovic writes in a blog post: "The shop/hire-rate-reward feedback loop has become baked-in to some systems. Many live marketplaces incorporate these feedback transactions into ratings, which then become a score which then impacts future prospects of whomever is being rated. And that's where the trouble starts. There is a point where this stops being useful and the knock-on effects of a ratings system predicated on feedback results becomes counter-productive. That point is when the ratings become targets. When a company decrees 'All customer feedback ratings must score a minimum of X, or else...' the company has just commenced the process of invalidating and corrupting all useful information to be gleaned from that feedback/survey process. A label which captures this concept is 'Goodhart's Law' -- after economist Charles Goodhart, who posited in essence that 'when a measure becomes a target, it becomes useless.'"

    Due to the growing abusiveness or corporations, invasions of privacy, and wide spread deceit, I have decided to follow the principles that many corporations expose and purposefully lie in feedback to companies I dislike. They want quality consulting services, well, the fuckers can bloody well pay for them, nothing is for free according to them, for free, they just get lies. Turnabout is fair play after all, lie to me, well I'll lie to you ;) (only for poorly behaved corporations, which seems to be the majority, especially multi-nationals).

    • How do I get honest feedback? I mean, I'm actively developing software, and adding new features. I would love to be told "most of your customers want X before Y" (or most of your on-the-fence non-customers). That seems to be a win-win for everyone (except those minority who want Y, but that would be true of any system that accurately measured).

    An experience at a local biz in town with a customer service rep... Was told that anything less than 5 out of 5 on his customer review is considered a bad review, and he all but begged me to give him 5-stars.

    He was so overly friendly it was past creepy. I felt conflicted: he did a good job, but I felt I was rating for his sake, not to give an honest assessment of how well I was served by him.

The impression I got was that I'd better voice my complaints to his face right now or keep my trap shut later when they call with the survey. I was looking forward to telling the survey person that I'm giving a 10\10 rating because he threatened to harass me if I didn't, but they didn't end up calling.

        The end of my story was that I did not fill out any survey. Life is too short for me to be filling out surveys every time I am asked. I get them from the doctor's office, the car dealership, random items bought online, and my cat.

        • I rarely fill them out, typically only if it's a couple of questions.

          You know what *really* works when you get excellent service? Write a letter to the manager. I have a former neighbor who is 85 years old and she mentioned this a few years back. When she gets excellent service in a restaurant or whatever she hand-writes a letter to the manager mentioning the employees by name. She often gets letters back thanking her. That's how you reward excellent service.

      Another aspect of this that's weird to me:

      I was sent a survey to rate a business I frequent-- not to be posted online, just as feedback to the owner. I was asked to rate my experience on a scale of 1 to 10. If I selected 10, it asked the question, "What did you like about your experience?" I selected 8, and the question automatically changed to "What did we do wrong?"

      I didn't think they did anything wrong, but to me, the service warranted an 8. To me, 8 is good, just not quite excellent. So I answered the question, "It's not that you did anything wrong. I liked [a bunch of stuff]. In my opinion, you could improve by [doing some things]." I thought it was a very fair review, and I tried to give constructive feedback. I few days later, I got a phone call from the owner to apologize. It wasn't quite annoying, but it definitely seemed unnecessary and awkward, but I said thank you and reiterated that I thought the service was good, and I didn't intend the rating of 8 as a complaint.

      Since then, the business has continued to send me requests for feedback. My overwhelming feeling is not wanting to go through that experience, so I either just rate them a 10, or I ignore the survey entirely.

      • The problem with an arbitrary 1-10 or 5-star/point rating system is that every person defines their rating in a slightly different way. For instance, I've seen people knock a star off a rating for a game or movie because "nothing is perfect", meaning that apparently they'll *never* give 5/5 stars. On the other hand, many people seem to operation in a binary mode, rating 5/5 for anything moderately good, while anything they don't care for is 1/5. Some people define 5/10 as "average", while others imply th

        I dunno. Take a call centre. ASA (average speed of answer) is a common and important metric. Organisations will often have a target or SLA for their ASA, and this is something customers really care about. It's driven by a range of factors: how call centre operatives handle calls, matching of demand and supply, actions to reduce demand such as self-service (eg online) or bots to answer, etc etc. I can't see how a call centre could manage itself effectively without having both an ASA target for the centre as

            shilly addressed this point in the parent post. Crudely looking at success rates, and over-incentivising them is bad. Not collecting the data because it is liable to misinterpretation is not the solution, however. There are huge benefits in clinical outcomes available by using these metrics sensibly; even some counterintuitive things like closing some regional units - because they saw the trickier cases too rarely to keep their clinical skills up to date.

    For every second you're not selling, you're costing someone money. For every second you're not adding value to that sale, you're costing someone money. For every second you're spending getting to know that other human, you're wasting someone else's money. That's how retail works now. How's it's been working for the past 15 years or so when those got first introduced. It was never about getting someone to better themselves. It was always about manipulation.

    If you want to reward someone for doing a good job, you can tell a manager (look for someone walking around the store who looks like a manager), or go to the store's "Customer Service" department, and tell them. Be specific as to how that person was helpful.

    Once in a busy pre-Christmas shopping season, a store employee went out of his way to help me. I told a manager, who was walking around the store, how much that employee had helped me. About 1/2 later, the employee rushed up to me all happy. He thanked me for telling the manager how helpful he had been. He said that because of what I'd said, he'd gotten a star (whatever that is) and a bonus.

    I think it's also important to consider that satisfaction surveys tend to suffer from a sort of selection bias. You're only getting feedback from people who feel compelled to give feedback. In my personal experience you'll get:

    - Sometimes people who are angry
    - Occasional people who are extremely pleased
    - Often people who have excessive esteem of their own opinions**
    - Rarely people who just want to give helpful feedback

    I'm not pointing this out to necessarily disparage these groups or say that their opinions aren't valid, but it's important to understand you're unlikely to get a true random sampling.

    **I know someone is going to take issue with my third item, "people who have excessive esteem of their own opinions", so I'll try to explain what I mean by that. Obviously people's opinions are important, or you wouldn't be asking for feedback. And yes, everyone values their opinions more than others'. However, there are some people who... you read their online review, and you can tell that they believe their review will impress everyone and settle all disputes. Like you'll read a negative Yelp review, and the reviewer isn't just saying, "I had an bad experience," or "I didn't like it," but something more like, "This place is simply objectively terrible and though I see other people saying that they like the place, they're all wrong and stupid and not worth listening to." You can almost imagine that they've finished writing the review, leaned back in their chair, and thought, "Well that waiter crossed the wrong person.

      I worked for a big, big global company for a number of years. IT was run from call centres around the world, so that anybody working anywhere would always find somebody in a convenient timezone to work on the problem for at least a few hours, even if the ticket was submitted at the end of the business day for the person with the problem.

      And if the IT people fixed the problem quickly, there was always a request to complete a satisfaction survey.

      Curiously, if they didn't fix the problem quickly, there was no

  • I also once read that customer satisfaction surveys are, in general, only answered by people who were on the extreme ends of the customer satisfaction ratings; that is, most of the time the only people who bother with a survey are those who had a really awesome or a really bad experience. The experience left them emotionally charged, and they feel the need to share/vent, and the survey gives them that opportunity. The average customer, on the other hand, doesn't have this emotional need and so - when offered an opportunity to rate their experience, gives the whole thing a pass and - if forced into it - tend to give wishy-washy middle-of-the-road answers (e.g., all 5 out of 10s) just so they don't have to think about it.

    I imagine it is also easier to be on the receiving end of a "terrible experience" than an awesome one too, which only further biases the reviews. I mean, as a customer I can imagine a dozen ways in which a cashier could piss me off, but have a hard time thinking up a way that cashier could make me EXCITED about paying for my groceries). So the end result is very biased against the person getting reviewed, because most of the people who bother to respond to the reviews are those who had a bad experience. If they forced /all/ customers to take the survey and somehow ensured their honesty, you might get a better overview of how the employee is performing, but by leaving it up to the customer the employer is getting a very unbalanced response.

    Not to mention I never know how to answer those because I never know what is considered "average". Is a 5/10 average or do I have to base it on the US grading system, where 7/10 is "average"?

    • Well, I have dealt with several companies which have apparently decided to fix the problem with people not responding to surveys by repeatedly emailing me to piss me off enough to respond to the survey. I usually put in the comments, "I have no idea what the issue was that this ticket was about any more, nor do I remember what the service was like, but you badgered me with emails to fill out this survey often enough to make me angry."

    I don't think these surveys are worth crap. The companies that rely on them to rate employees have HR policies that suck. I usually just ignore the pleas from "anonymous data collectors" about my visit to see my doctor, or the pizza order (really!). When an employee implores me to rate my visit (for which she is being held responsible) highly, in what might be a personalized way, I just rate the "experience" at 10's from start to finish unless they performed some egregious bit of malpractice on me or my car. It's like tossing a fiver into the hat of a street musician. He needs it and it costs nothing to help him out. I'm hoping that after seeing a few of these the companies will stop asking for my meaningless "feedback". Otherwise, I will continue (with little enthusiasm or optimism) to try to improve the quality of life for those who depend on 10's.
