What does the customer want? David and Sarah Kerridge Summary To learn how to improve service, we must know what will benefit the customer. The obvious way to find out is to ask: conduct a survey. Properly designed surveys are an important tool of Market Research, but surveys do not always give reliable results, and some even do harm. We give some of the reasons for this, and describe other sources of information. Introduction At a one-day seminar in 1989, Dr Deming was answering questions from the audience. One was: "How should we ask the customer what he wants?" His reply was unexpected and thought-provoking. "Customer? What does he know about it?" This sounds surprising: after all, Dr Deming teaches us to regard as the customer as the most important part of the system. But he went on to give many examples which show that the customer rarely knows what he wants. For example, before developing the first photo-copying machines, the Xerox Corporation paid for a large, expensive, survey to estimate the market for office copiers. This market research said there would be no demand for them. As Dr Deming says, everyone thought Firestone was mad to develop pneumatic tyres, when solid tyres were obviously more reliable. There are many similar examples: if you wait until customers know what they want, you lose the customers. The customer does not always know In the Xerox example the customers were asked about something they had never seen. The demand did not exist until the service was provided. Is it any better when you ask about familiar things? Sometimes it is: if you ask strictly factual questions, such as which items have been purchased, or which services have been used, the replies may be less inaccurate. Even so, memory plays strange tricks. Customers systematically underestimate the number of cigarettes they smoke, for example. Market research firms have conducted experiments in which consumers put the packaging from every item used into a special bin, so that the total usage is accurately known. The results differ greatly from answers based on memory. Observed behaviour is always more reliable than stated opinion. The sample must not be misleading Quite apart from errors in reporting, it is important to get a good sample. If you rely only on customers who take the trouble to fill in and return forms, the results will be biased. The ones who answer may be the most helpful, or the least busy, or even the ones who like complaining. What is worse, you learn nothing about the most important group, the customers you could have had, but failed to get. The questions must be carefully chosen I never cease to be amazed at some of the questions asked in surveys of this type. For example, after a rail journey on a train that ran late and was far from clean, I was asked to fill in a form containing questions like: "Did the train arrive on time?" "Was the train clean?" Do they not know what their trains are doing? Or are they trying to find out whether we notice when things go wrong? Perhaps both. It gives a very poor idea of their quality systems. When you ask for opinions, like "Would you prefer....?" or "Are you satisfied with...?" expect problems. Both experience and theory tell us that the answers rarely mean very much. To take an extreme case, suppose that you want to know what your own staff, as internal customers, feel about their conditions of work. You could design a survey, with questions such as: Are you paid A) too little B) too much C) enough Do you work A) not enough B) too hard C) just right The answers are so predictable that they tell you nothing. You might think no one would ask such silly questions, but I have seen some nearly as bad. One questionnaire asked, in a slightly concealed form, if customers would prefer lower prices. No doubt the aim was to find out whether customers would prefer lower prices, or better service. But why ask? Continual improvement will produce both. Surveys may do harm The concealed purpose of many customer surveys is to check up on staff. The size of bonus depends on the scores obtained. If your employees know that you are checking up on them, and asking customers to report on them to management, this will destroy the atmosphere of trust and pride of workmanship that you must strive to create. Another gross misuse of a survey is as a public relations exercise. A company once asked me to design and supervise a survey. When I became suspicious, and questioned with great persistence, the company admitted that the sole reason for doing the survey was to present a caring image. They had no intention of using the results. In another case, a hotel admitted that the "customer satisfaction" forms were largely ignored: but they allowed customers to express irritation harmlessly. In both these cases there is an attempt to fool the customers. Even if it succeeds in its aim, and we ignore the ethics involved, it does great harm to the organisation. It encourages an attitude to customers which makes sure that quality will not improve. This does not mean that customer surveys will never do any good. If there is something that irritates a large number of customers, you will find out fairly quickly. On the other hand, a really good survey is expensive and can not be hurried. This means it is difficult to use surveys repeatedly, as part of the PDSA cycle. It makes sense to see whether there are any other ways to get the same information. Why do you want to know? Before we start to gather information, we should spend time in planning. The first question is not what do we what to know, but why do we want to know. Ask first "what will we do with the information when we have it?". For example, managers sometimes say they want to know how well the organisation is pleasing its customers. Even if such a question can be given operational meaning, what difference does it make? The action, to work for continual improvement, should be the same whatever the answer. We should concentrate on improving all the processes. Provided these processes contribute to the aim of the system, the overall outcome will take care of itself. A good reason for wanting information is to identify trends, such as changes in customer behaviour, that affect planning for the future. For example, an airline must keep an eye on the balance between business and holiday traffic, or scheduled as against charter flights. Analysis of customer complaints by type can be useful in some ways, but total numbers can be misleading. A rise in the number often simply means that complaints are being dealt with more sympathetically. Something similar affects crime figures. The more effective the police force, the more crimes are reported. Information about potential customers sometimes must come from surveys. Information about existing customers can often be gained more cheaply and conveniently from sales or other records. Records will only be useful if they are very well kept, but excellence of records should be taken for granted in a quality organisation. In fact, if record-keeping is improved enough to make surveys less necessary, there will be many other benefits. Concentrate on process rather than outcome Although we obviously want to have satisfied customers, measures of this outcome may not be the most helpful information for making improvements. We must remind ourselves of the true nature of quality. Of course we must satisfy the customer. This just means that there are no complaints, but a policy based on avoiding complaints is too negative. A satisfied customer may be just as satisfied somewhere else. We should continually think of ways to increase benefit to customers, not just satisfy obvious needs. Delighted customers, who get more than expected, not only keep coming back, but bring friends along as well. The way to achieve this is the continual improvement of every process which contributes to the final result, not just the processes directly visible to the customer. When the attention is focused on processes, rather than overall outcome, it is much easier to decide what information to gather. The numbers of mistakes in invoices, the time a patient has to wait, or the rates of staff turnover and absenteeism, are valuable in answering specific questions, and not difficult to study. Ideas for innovation in service Successful innovation depends on information, but usually needs a depth of insight into customer thinking that is hard to get from a questionnaire. In depth studies of special groups - a standard market research technique - may be more helpful. But the best source of information for this purpose is usually your own staff. Before designing surveys, make sure that all your staff are looking for ways to make improvements. The providers of each service usually have direct contact with customers: far more than the managers. They should be the first to know how customers respond. Managers are more likely to learn by being customers themselves. Everyone uses services. Managers of an airline are bound to travel themselves: they should sometimes fly economy class, or with a competitor. Completely new ideas are best tried out on a small scale, sometimes called test marketing. This one obvious advantage that service industries have over manufacturing: it is much more expensive to test market a new car. The design and analysis of such trials must be done on sound statistical principles. Break down barriers In most organisations, staff at all levels know of ways in which goods or services could be improved. Usually, unless the Deming philosophy has taken a firm hold, they do nothing about it. There are various reasons for this, all of which spring from neglect of Dr Deming's 14 points. Here are just a few: 1) Lack of communication between different departments, or different levels. 2) The feeling that managers will take no notice - "workers are paid to do what they are told, not paid to think". 3) The fear that managers will treat all suggestions as criticism. 4) The fear that improvements in efficiency will lead to more work, without increased reward, or alternatively less work, leading to redundancies. .....and so on. All of these are based on experience. Until you know what to look for, you are unlikely to see them. Or perhaps, until you know that such problems can be removed, you accept them as inevitable. Such barriers always exist, until transformation is far advanced. The process of finding and destroying them is a potent means of improvement. Just saying that suggestions from the work- force are welcome is not enough. The members of the organisation must know from experience that any suggestion made will be taken seriously by the management, and either acted on promptly, or the reasons why not fully explained. Conclusion There is no doubt that surveys can be useful: in many cases essential. But never commission a survey without careful thought. Before you start, ask several questions: 1) Could we get the information we need from existing records? 2) If the information recorded is not accurate enough, can we improve the records? 3) Do our own staff already know the answers? 4) If so, have we ignored what they tell us, are they afraid to tell us, or have we not asked them? Do we not trust them? 5) If they ought to know the answers, but do not, why is this? 6) Would a survey give reliable enough answers? If, after all this, you are still sure that a survey is the best way to get what you need, make sure that it is designed and executed on sound statistical principles. Good surveys are costly and difficult, and expert help will be needed. In the right place, and correctly carried out, the survey is an important tool of continual improvement. A bad survey is worse than none at all. It will give false information, and lead to expensive mistakes. Make sure that you consider the psychological impact of everything you do. This may be greater than the obvious effect. While bad surveys can do harm, getting the whole work-force to think of improvements is bound to do good. It produces a state of mind in which service to the customer is seen to be important.
