There are many ways to collect catering information, such as questionnaire survey, copywriting survey, field survey and observation survey. No matter which method is adopted, the authenticity and accuracy of the survey results must be achieved. Questionnaires are the most common means of investigation in the collection of catering information, and it is a highly scientific and artistic work. It requires designers and practitioners not only to understand the basic principles and methods of marketing, but also to have knowledge literacy in sociology and psychology. The questionnaire survey mainly grasps the following methods and skills: 1. Sort out the basic elements of the questionnaire, clarify the purpose and requirements of the questionnaire, determine the respondents, and clarify the main characteristics of the respondents, such as name, age, gender, nationality, education level, occupation, unit, economic situation, etc. Then put forward the relevant issues that need to be investigated, and get the understanding and support of the respondents. 2. Sort out the questions in the questionnaire survey. Such as true or false questions, multiple-choice questions, sorting questions, true or false questions, recalling questions, distinguishing questions, checking questions, comparing questions, filling in the blanks, asking questions and so on. 3. Follow the principle of arranging questionnaires. When setting up the questionnaire, all the questions to be investigated should be arranged into appropriate questions, which are convenient for the respondents to understand and fill in easily. At the same time, we should master the principles of questionnaire setting; First, it is conducive to asking questions, second, it is conducive to understanding, third, it is conducive to collecting necessary information, and fourth, it is conducive to data sorting and analysis. 4. Master the skills of arranging questionnaire survey settings. When arranging the contents of the questionnaire, we should first be simple and then complex, and adopt the filtering principle. For example, if you want to investigate what kind of beer customers want to drink, you can first ask if you like beer, then ask what kind of beer you like to drink, and finally ask if you like the beer brewed in our hotel. The time sequence should be from far to near. For example, if you want to know the time and frequency of customers coming to your restaurant, you can set the following questions in turn: the time when you first came to our restaurant, the number of times you came to our restaurant this year, the time and frequency of spending in our restaurant in the past month or week, and so on. In terms of content arrangement, basic information is generally followed by classified information. Basic information refers to the customer's name, gender, age and other information. Classification information is to classify what we need to know, such as food quality, price rationality, restaurant environment and other issues, and promote them one by one. Generally speaking, difficult or sensitive questions are best arranged at the end of the questionnaire. There are two methods of questionnaire, one is written questionnaire, which is filled out by customers themselves; One is that the investigator orally asks the customer questions, which are filled out by the investigator. Copywriting investigation is to obtain information from various newspapers, magazines, documents, internet and other channels. Its characteristics are low cost, high speed, wide sources of information, few controllable factors, less time-saving and less expenses, and its disadvantage is poor timeliness of information content. Copywriting investigation method can be divided into the following types according to data content: 1, and can be divided into original information and processing information according to data sources. The original information is obtained directly from relevant materials and guest complaints and suggestions; Processing information is the material processing information that is sorted out by sorting out and summarizing the original information and putting forward the corresponding viewpoints. 2. According to the timeliness of data, it can be divided into past information, current information and forecast information. The previous information reflects the past situation, such as how many hundred million yuan the national catering market sold last year, and which units were in the top 100 catering enterprises. At present, information is obtained from current or recent reports and the internet, such as what dishes are popular in a certain place; Forecast information is a forecast report based on the comprehensive analysis of static and dynamic information content. 3. According to the access channels of data, it can be divided into formal channel information and informal channel information. Official channel information generally comes from government reports, as well as various statistical reports, laws and regulations. Informal channel information is information obtained from personal surveys and various social activities. 4. According to the concept of data, data can be divided into macro information and micro information. Macro information refers to the overall situation, such as citizens' purchasing power, consumption structure, lifestyle and traffic conditions. Micro-information refers to specific situations, such as the source market of the enterprise and the operation of competitors. Copywriting law mainly collects information from three aspects: first, government-related policies and documents, such as national economic development planning, urban planning, prices and consumption levels of neighboring cities. Information required by catering enterprises, such as the income and expenditure of local residents, the proportion of catering consumption in the total expenditure, customers' demand for catering enterprises in service and food quality, and the consumption psychology of food quantity and price. To help enterprises adjust their business ideas and directions; Third, the information of catering competitors, such as product variety, price, technical strength, facilities and equipment, advertising investment, marketing methods, food festival promotion activities, customer file management and operating conditions. , can be collected to know yourself and yourself, and provide reference materials for formulating the business strategy and strategy of this enterprise. Copywriting investigation methods: First, ask the government planning, statistics, finance, banking, business administration and urban construction departments for relevant information; The second is collection, that is, collecting relevant materials and information from newspapers, internet, advertisements and other channels; The third is entrustment, that is, entrusting friends and customers of foreign or local competitors to collect the required information; The fourth is to summarize and classify the customer files and sales records of the enterprise for many years according to the needs, and summarize them into the skills that the enterprise needs, such as collecting information from the former or current employees of competitors, hiring senior staff, managers and technical backbones of the other side at a high salary through legal means, obtaining relevant business information from competitors' buildings, decoration units, suppliers, assisting units, customers and consumers, and understanding the competition situation from public publications, advertisements and documents.
