COMMUNICATION MODELS IN A DIGITAL WORLD THAT IS “ALWAYS ON”

 

movieVideo Lesson: Overview of Communication (Duration: 6.06 mins)

Promotion is the coordination of marketing communication efforts to influence attitudes or behavior. This function is one of the famous four Ps of the marketing mix, and it plays a vital role. Of course, virtually everything an organization says and does is a form of marketing communication.

Marketing communication performs one or more of four roles:

  • It informs consumers about new goods and services.
  • It reminds consumers to continue using certain brands.
  • It persuades consumers to choose one brand over others.
  • It builds relationships with customers.

Integrated marketing communication (IMC) is the process that marketers use “to plan, develop, execute, and evaluate coordinated, measurable, persuasive brand communication programs over time to targeted audiences.

To achieve marketing communication goals, marketers use a multichannel promotional strategy where they combine traditional marketing communications (advertising, sales promotion, public relations, and direct marketing) activities with social media and other online buzz-building activities.

 

Models of Marketing Communication

movieVideo Lesson: Models of Marketing Communication (Duration: 11.45 mins)

  • The traditional communication model is a “one-to-many” view in which a marketer sends messages to many consumers through advertising, including mass media; out-of-home, such as billboards; and Internet advertising.
  • The importance of the updated “many-to-many” model of marketing communication has increased because of social media and its use in word-of-mouth communication, whereby consumers look to each other for information and recommendations.
  • Marketers also talk one to one with consumers and business customers.

 

The Communication Process

CommunicationProcessModel3

Figure: Communication Process

Promotional strategies can succeed only if customers understand what we’re trying to say. The communication process is a good way to understand the basics of how any kind of message works. In this perspective, a source transmits a message through some medium to a receiver who (we hope) listens and understands the message.

  • The Source Encodes
    A person or organization, the source has an idea to communicate to a receiver. Encoding means we can translate our idea into different forms to convey the desired meaning.
  • The Message
    The message is the actual content of that physically perceivable form of communication that goes from the source to a receiver.
  • The Medium
    No matter how the source encodes the message, it must then transmit that message via a medium, a communication vehicle that reaches members of a target audience.
  • The Receiver Decodes
    A receiver is there to get the message. Decoding is the process whereby a receiver assigns meaning to a message; that is, she translates the message she sees or hears back into an idea that makes sense to him or her.
  • Noise
    The communication model also acknowledges that noise—
    anything that interferes with effective communication—can block messages.
  • Feedback
    To complete the communication loop, the source gets feedback from receivers.


TASKS SELF-CHECK ACTIVITY

As you were going through your day you were exposed to many forms of marketing communication. However, noise probably interfered with most of the exposures.

  1. List TWO (2) different instances where noise interrupted your ability to decode a marketing message.
  2. Explain what, if anything, a marketer could have done to help limit some of the noise

Updated Web 2.0 Communication

Web 2.0 refers to the internet that allows receivers to play a role as the sources. Web 2.0 changed the way we look at the communications process.

  • The One-to-Many Model: This model is the traditional form of mass communication whereby a broadcaster sends a message to a very large audience
  • The One-to-One Model: This format describes messages that are up close and personal. This is the oldest way to communicate, but it’s still important in many marketing contexts today.
  • The Many-to-Many Model: This format describes the social media revolution that allows almost everyone to engage in a constant conversation with almost everyone else.

Outbound marketing refers to messages that come from the organization and are intended for those who have agreed to receive them. Inbound marketing marketing methodology that is designed to draw visitors and potential customers in, rather than outwardly pushing a brand, product or service onto prospects in the hope of lead generation or customers.

 

 

Mass Communication: The One-to-Many Model

Mass communications elements of the promotion mix include messages intended to reach many prospective customers at the same time.

  • Advertising is, for many, the most familiar and visible element of the promotion mix. It is nonpersonal communication from an identified sponsor using the mass media. The most important advantage of advertising is that it reaches large numbers of consumers at one time.
  • Consumer sales promotion includes programs such as contests, coupons, or other incentives that marketers design to build interest in or encourage purchase of a product during a specified period. Unlike other forms of promotion, sales promotion intends to stimulate immediate action (often in the form of a purchase) rather than build long-term loyalty.
  • Public relations describes a variety of communication activities that seek to create and maintain a positive image of an organization and its products among various publics, including customers, government officials, and shareholders.

Personal Communication: The One-to-One Model

  • Sometimes marketers want to communicate with consumers on a personal, one-on-one level. The immediate way for a marketer to make contact with customers is simply to tell them how wonderful the product is. This is part of the personal selling element of the promotion mix mentioned previously. It is the direct interaction between a company representative and a customer. The interaction can occur in person, by phone, or even over an interactive computer link. Behavioral targeting makes it possible for an online source to tailor a message to a specific consumer based upon what that person has viewed in the past.
  • Salespeople are a valuable source of communication because customers can ask questions and the salesperson can immediately address objections and describe product benefits. Marketers also use direct mail, telemarketing, and other direct marketing activities to create personal appeals. Like personal selling, direct marketing provides direct communication with a consumer or business customer.

 

OVERVIEW OF PROMOTIONAL PLANNING

Just as with any other strategic decision-making process, the development of this plan includes several steps.

movieVideo Lesson: Promotional Planning

Part 1 (Duration: 12.45 mins)

Part 2 (Duration: 8.20 mins)

 

Step 1: Identify the Target Audience(s)

  • An important part of overall marketing planning is to identify the target audience(s). Remember, IMC marketers recognize that we must communicate with a variety of stakeholders who influence the target market. Of course, the intended customer is the most important target audience and the one that marketers focus on the most.

Step 2: Establish the Communication Objectives

  • The whole point of communicating with customers and prospective customers is to let them know in a timely and affordable way that the organization has a product to meet their needs. In most cases, it takes a series of messages that move the consumer through several stages.
  • The marketer “pushes” the consumer through a series of steps, or an of-effects from initial awareness of a product to brand loyalty. The task of moving the consumer up the hierarchy becomes more difficult at each step. The steps are as follows:
    • Create awareness
    • Inform the market
    • Create desire
    • Encourage purchase and trial
    • Build loyalty

Step 3: Determine and Allocate the Marketing Communication Budget

  • While setting a budget for marketing communication might seem easy—you just calculate how much you need to accomplish your objectives—in reality it’s not that simple. We need to make three distinct decisions to set a budget:

Budget Decision 1: Determine the Total Promotion Budget

    • Most firms rely on two budgeting techniques: top-down and bottom-up. Top-down budgeting techniques require top management to establish the overall amount that the organization allocates for promotion activities. The most common top-down technique is the percentage-of-sales method in which the promotion budget is based on last year’s sales or on estimates for the present year’s sales. The percentage may be an industry average provided by trade associations that collect objective information on behalf of member companies. The advantage of this method is that it ties spending on promotion to sales and profits. Unfortunately, this method can imply that sales cause promotional spending rather than viewing sales as the outcome of promotional efforts.
    • The competitive-parity method is a fancy way of saying “keep up with the Joneses.” This method assumes that the same dollars spent on promotion by two different firms will yield the same results, but spending a lot of money does not guarantee a successful promotion. Firms certainly need to monitor their competitors’ promotion activities, but they must combine this information with their own objectives and capacities.
    • The problem with top-down techniques is that budget decisions are based more on established practices than on promotion objectives. Another approach is to begin at the beginning: identify promotion goals and allocate enough money to accomplish them. 
    • That is what bottom-up budgeting techniques attempt.
    • This bottom-up logic is at the heart of the objective-task method which is gaining in popularity. Using this approach, the firm first defines the specific communication goals it hopes to achieve, such as increasing by 20 percent the number of consumers who are aware of the brand. It then tries to figure out what kind of promotional efforts—how much advertising, sales promotion, buzz marketing etc. —it will take to meet that goal.

Budget Decision 2: Decide on a Push or a Pull Strategy

    • push strategy means that the company wants to move its products by convincing channel members to offer them and entice their customers to select these items—it pushes them through the channel. This approach assumes that if consumers see the product on store shelves, they will be enticed to make a trial purchase. In this case, promotion efforts will “push” the products from producer to consumers by focusing on personal selling, trade advertising, and trade sales promotion activities such as exhibits at trade shows.
    • In contrast, a company that relies on a pull strategy is counting on consumers to demand its products. This popularity will then convince retailers to respond by stocking these items. In this case, efforts focus on media advertising and consumer sales promotion to stimulate interest among end consumers who will “pull” the product onto store shelves and then into their shopping carts. 

Step 4: Design the Promotion Mix

  • Designing the promotion mix is the most complicated step in marketing communication planning. It includes determining the specific communication tools that will be used, what message is to be communicated, and the communication channel(s) to be employed.
  • The message should ideally accomplish four objectives (though a single message can rarely do all of these): It should get attention, hold interest, create desire, and produce action. These communication goals are known as the AIDA model.

The Promotion Mix

Marketers use the term promotion mix to refer to the communication elements that the marketer controls.

  • Media advertising
    • Out-of-home advertising
    • Point-of-purchase advertising
    • Social media
    • Digital/Internet advertising
  • Sales promotion
  • Public relations
  • Personal selling
  • Direct marketing

The challenge is to be sure that the promotion mix works in harmony with the overall marketing mix to combine elements of promotion with the place, price, and product to position the firm’s offering in people’s minds.


Step 5: Evaluate the Effectiveness of the Communication Program

  • The final step to manage marketing communications is to decide whether the plan is working. It is not so easy. There are many random factors in the marketing environment.
  • As a rule, various types of sales promotion are the easiest to evaluate because they occur over a fixed, usually short period, making it easier to link to sales volume. Advertising researchers measure brand awareness, recall of product benefits communicated through advertising and even the image of the brand before and after an advertising campaign.
  • The firm can analyze and compare the performance of salespeople in different territories, although again it is difficult to rule out other factors that make one salesperson more effective than another does. Public relations activities are more difficult to assess because their objectives relate more often to image building than sales volume.

 

Multichannel Promotional Strategies

Many marketers opt for multichannel promotional strategies where they combine traditional advertising, sales promotion, and public relations activities with online buzz-building activities.

Multichannel strategies boost the effectiveness of either online or offline strategies used alone. In addition, multichannel strategies allow marketers to repeat their messages across various channels; this lets them strengthen brand awareness and provides more opportunities to convert customers. Multichannel campaigns need to provide a customer experience that will engage the customer and add something of value (in addition to the product) to the customer’s life.

Marketing Series: Conducting International Marketing Research

 International Marketing Research

By the end of this topic, you should be able to:

  1. Discuss the breadth and scope of market research in the context of the international market and the four steps involved in the research process; 
  2. Explore the issues of the availability of secondary data and the need to validate data; and
  3. Elaborate on the problems faced in gathering primary data.

INTRODUCTION

movieVIDEO LESSON: Introduction to Marketing Research


Information is a critical factor in formulating and implementing a successful marketing strategy. Given the complexity of today's fast-changing world and the unpredictability of consumer demands, marketing research is essential for a company to reduce serious risks associated with marketing a product. Thus, the purpose of this topic is to examine the nature and techniques of international marketing research. In addition to this, the process and challenges of gathering data in international markets will also be explained. The discussion will focus on the difficulties associated with cross-cultural research and the necessity of adapting marketing research techniques to the international market.

 

THE NATURE OF MARKET RESEARCH

Marketing research involves the "systematic gathering, recording, and analysing of data about problems relating to the marketing of goods and services". In this context, international marketing research is carried out on an international scale. Generally speaking, international marketing research can be defined as research that crosses national borders and involves respondents and researchers from different countries and cultures. 

movieVIDEO LESSON: The challenge of International Marketing Research

 

The challenge of international marketing research is to recognise and respond to the national differences that influence the way information can be obtained. These include cultural, linguistic, economic, political, religious, historical, and market differences. The objectives of international market research are similar to the objectives of domestic research. However, five specific environmental factors that may require international research efforts to be conducted differently from domestic research:

  1. Researchers must be prepared for new parameters for doing business;
  2. Not only will there be different requirements, but the ways in which rules are applied may differ as well;
  3. Cultural mega shock may occur as company personnel come to grips with a new set of culture-based assumptions about conducting business;
  4. Entering more than one new geographic market may result in a burgeoning network of interacting factors; research may help prevent psychological overload; and
  5. Company researchers may have to broaden the definition of competitors in international markets to include competitive pressures that would not be present in the domestic market.

 

STEPS IN THE RESEARCH PROCESS

The process of collecting data and converting it into useful information is shown in detail below. In the discussion that follows, the steps in the research process will be presented and elaborated upon.

movieVIDEO LESSON: The Steps in Marketing Research

 

IM1

Step 1: Define the Research Problem and Establish Research Objectives
This step is the most difficult and crucial step, where the researcher has to convert a series of often ambiguous business problems into a pragmatic and achievable research objective. This first task, which sounds deceptively simple, may be the pivotal task in the entire study. In defining the problem, there are two important considerations that a researcher has to observe; namely the market structure and the product concept.

movieVIDEO LESSON: Defining the Research Problem

 

  1. Market structure refers to the size of the market, its stage of development, the number of competitors and their market shares, and the channels through which the market is approached.
  2. A product may be viewed differently in different cultures. Before attempting to define the marketing research problem, exploratory research may be necessary to understand the product concept, that is, the meaning of the product in a particular environment.

For example, Berent points out that milk-based products are viewed very differently in the United Kingdom and Thailand. In Britain, milk-based products are usually consumed at meals and bedtime for their sleep-inducing, soothing, relaxing properties. In Thailand, the same products are consumed on the way to work and often away from home for they are considered invigorating, energising, and refreshing.

Back-to-School-Lunches-YOUGURT-200x300

Let us assume a multinational marketer is interested in finding out the potential market for a brand of yogurt in Britain and Thailand. In this context, the definition of the problem in the two countries will have to be stated differently. In the United Kingdom, yogurt might be primarily perceived by the consumers as a healthful and relaxing product to be consumed prior to retiring. In Thailand, the research problem would be to determine if yogurt would be considered mainly as an energy food that is eaten to start the day.

 

Step 2: Determine the Sources of Information to Fulfil the Research Objectives
After the problem has been defined, the next step is to determine where the necessary information is located and how to obtain it. In some cases, the study may be confined to secondary data, that is, published information that has been collected elsewhere. Secondary data may be available for free (e.g. from government statistics), or for
a price (e.g. from syndicated research suppliers) or through restricted distribution sources (e.g. from trade association statistics).

movieVIDEO LESSON: Determining the Sources of Information

 

Let us assume that the Ford Motor Company is interested in assembling its new car in collaboration with an Indian company. Before committing itself to the joint venture, Ford would like to study the car's market potential in India over a ten-year period. Fortunately, the Indian government collects a variety of socioeconomic-demographic information on a regular basis. Ford, therefore, can use such secondary information as population projections, income data, consumer expenditure patterns and rural-urban population shifts to assess the market potential.

 

Sometimes internal data are also useful. Existing files can often provide important insights into the question at hand. In the above example, Ford might have found that it already had sufficient information on population trends in India gathered when the company had earlier negotiated the assembly of tractors there.

In cases where the secondary sources or internal data cannot provide the necessary information, primary data will have to be compiled from scratch through interviews and other direct collections of information. Primary data may be gathered in various ways, from trade association representatives, government experts, managerial personnel and/or the buying public.

For example, a company may be interested in introducing its fabricated houses in Malaysia. The company would have to study house-buying behaviour in the target country. Since this type of information may not be available from secondary sources, primary data gathering is therefore necessary.

20180828163540994099

House ownership in different countries could also have completely different implications. The saying that "a man's home is his castle" is far more applicable in the United Kingdom than in the United States, where the geographic and social mobility of the population means that the regular exchange of homes is a commonplace experience during the life cycle of most families. Therefore, the decision-making patterns of a husband and wife, and the amount of effort spent in making a home-buying decision should be quite different between these two countries. Thus, the company has to learn through primary research the ways in which "houses" might mean "home" in various locales.


Step 3: Gather the Relevant Data from Secondary and Primary Sources
The actual collection of data must be planned and executed carefully. It should be noted here that tracking down reliable, usable data sources can be time-consuming. Thus, the use of personnel with knowledge of the country could help appraise what progress is being made. Interview questions must be tested for their appropriateness so that they produce the desired results.

movieVIDEO LESSON: Gathering Data

 

In developing a questionnaire, the researcher needs to conduct professional level interviews in two phases:
(a) Collect basic data; and
(b) Explore interview questions not anticipated at the start of the project.

Once the basic data has been collected, the process of cross-checking can begin. This step requires that all information be examined critically for its relevance. Cross-checking establishes the reliability of data by comparing one source with another.

 

Step 4: Analyse, Interpret and Present the Results
In the final step of the preparation of the report, the data must be analysed and interpreted. Here too, attention should be given to the cultural traits of the country under study.

movieVIDEO LESSON: Reporting the Research Findings

 

For example, in an examination of the beer market, it was found that beer was perceived as an alcoholic drink in Northern European countries, but was considered a soft drink in Mediterranean countries. As such, other products listed together with beer as alternative drinks would influence the research findings. Similarly, in Japan non-carbonated fruit juices are often substituted for bottled soft drinks. This is different in the United States. In brief, the significance of different perceptions of the same product in various countries must be taken into account.

 

Reports must be complete, factual and objective. It is particularly important to communicate the reliability as well as the limitations of the facts presented. Particular attention should be given to the following aspects of a report:

  1. Data sources must be identified. Different sources of data warrant varying degrees of confidence. For example, information on a Third World country obtained from the Malaysian Agency for International Development is probably more reliable than information gathered from the government of that country;
  2. Data projection must be explained. The statistical computations should be simplified as much as possible. A detailed description of the statistical procedures should be included in the appendix;
  3. The identity of all those interviewed should be included as well as their titles or qualifications. (Note that this rule does not apply to consumer research). When anonymity has been guaranteed, this requirement may have to be relaxed;
  4. The alternative nature courses of action developed from analysis and interpretation of the data must be labelled as such, clearly reserving to management the responsibility for selecting the appropriate course of action.

 

AVAILABILITY AND USE OF SECONDARY DATA

It seems that secondary data available in a foreign country has many problems and deficiencies in comparison with similar information available in the United States. Thus, the researcher must be aware of problems and deficiencies when interpreting information. The following deals with some of the issues that need to be considered when processing data.

Availability of Data In many developing nations, secondary data is very scarce. Information on retail and wholesale trade is especially difficult to obtain. In such cases primary data (PD) collection becomes vital.
Reliability of Data The reliability may be affected by data collection procedures. For example, the sample may not be very random, so the results cannot be assumed to reflect the behaviour of the total population. Even when a good sampling plan has been laid out, it may not be properly adhered to (that is, the interviewers might substitute subjects when those required by the sampling plan cannot be reached). In brief, numerous factors may affect the reliability of data. It may be difficult for the researcher to judge the reliability of secondary data available in a country. If the researchers are indeed concerned with reliability, they would be better off undertaking primary data collection.
Comparability of Data Multinational corporate executives often like to compare information on their host countries about matters such as reviews of market performance, strategy effectiveness in different environments and so on. Unfortunately, the secondary data obtained from different countries is not readily comparable.
Validating Secondary Data Checking the consistency of one set of secondary data with other data of known validity is an effective and often the employed method of judging validity. For example, a researcher might check the sale of baby products with a number of women of childbearing age and with high birthrates. The researcher may also check the number of patient beds in hospitals with the sale of related hospital equipment.
The Underlying Purpose of Data Collection Generally, the single most important source of marketing-related secondary data in a country is the government. The government as a political institution may not approach data collection with the same objectivity as a business researcher. This problem is particularly severe in developing countries where governments may enhance the information content in order to paint a rosy picture of economic life in the country. In this way, political considerations overshadow the reliability of the data. Thus, the researcher must ascertain that the data available is accurate within the limits of its source and that there are no hidden assumptions that might distort the information from the researcher's point of view.
Currency of Information Information gathering is an expensive activity. When the government has limited resources, data gathering becomes unimportant. Therefore, information may not be gathered as frequently as desired. The researcher needs to be very careful that the information available overseas has not become outdated.
Data Classification Another problem has to do with the classification scheme of available data. In many countries, the data reported are too broadly classified for use at the microlevel. For example, in Thailand, the category "construction equipment, machine and tools" includes large bulldozers as well as hand-operated drills. Therefore, a company that is interested in manufacturing heavy construction machines in Thailand may not be able to get a clear idea about the current availability of such equipment in the country from the information given under such a category.

SELF-CHECK: REFLECTION

 

In your opinion, why must a researcher be aware of problems and deficiencies when interpreting information?

> POST YOUR REFLECTION HERE <

 

PRIMARY DATA

Where secondary data do not provide adequate information input for management decision-making, primary data collection will be required. The collection of such data often entails high costs relative to its perceived value.  This stems from difficulties encountered in international marketing research.

Some of the factors include a lack of experience in many markets which may mean that more background data will need to be collected. Furthermore, the data are often less accurate or reliable than in comparable domestic studies. Primary data presumably provide more relevant information because they are collected specifically for this purpose in mind.

Problems in Gathering Primary Data

Primary data collection in a foreign environment poses a variety of problems that are rarely encountered in developed countries. These problems are related to social and cultural factors and the level of economic development, and can be grouped under three headings:

(a) Ability to Communicate Opinions The ability to express attitudes and opinions about a product or concept depends on the respondentÊs ability to recognise the usefulness and value of such a product or concept. It is difficult for a person to formulate needs, attitudes and opinions about goods whose use may not be understood, or those that are not in common use within the community, or those that are not available there.

For example, to describe their likes and dislikes of a product or describe the atmosphere of the department store they prefer to patronise, most respondents may be unable to phrase their answers. Respondents are unable to articulate certain types of responses.

(b) Willingness to Respond Even if the interviewee is successfully reached, there is no guarantee that he or she will cooperate and furnish the desired information. There are many reasons why an interviewee is non-responsive:

  1. Cultural habits in many countries virtually prohibit communication with a stranger, particularly for women. For example, a researcher simply may not be able to speak with a Saudi housewife on the phone to find out what she thinks of a particular brand.
  2. In many societies such matters as preferences for hygienic products and food products are too personal to be shared with an outsider. For example, in any South East Asian country, a woman may feel embarrassed to talk to a researcher about her choice of brand of the sanitary napkin, hair shampoo or perfume.
  3. Respondents in many cases may be unwilling to share their true feelings with interviewers because they suspect the interviewers may be agents of the government. This may be a problem, for example, when seeking information for the imposition of additional taxes.
  4. Middle-class people, in developing countries, in particular, are reluctant to accept their status and may make false claims in order to reflect the lifestyle of wealthier people. For example, in a study on the consumption of tea in India, over 70% of the respondents from middle-income families claimed they used one of the several national brands of tea. This finding could not be substantiated since over 60% of the tea sold nationally in India is unbranded generic tea that is sold unpacked.
  5. Some respondents who are willing to cooperate may be illiterate. Unfortunately, oral communication with them may also be difficult. In other words, their exposure to the modern world may be so limited and their outlook so narrow that the researcher would find it extremely difficult to elicit adequate responses from them.
  6. In many countries, privacy is becoming a big issue. For example, in Japan, the working classes are showing increasing levels of concern about the protection of personal information. Information that people are more anxious to protect includes income, assets, tax payments, family life, and political and religious affiliation.
  7. The lack of established marketing research firms in many countries may force the researcher to count on ad hoc help for gathering data. How far such temporary help may be counted on to complete a job systematically can only be guessed.

(c) Sampling in Field Surveys A good piece of research should reflect the perspectives of the entire population. This is feasible only when the sample is randomly drawn. Unfortunately, in many countries it is difficult to get completely representative information on the socioeconomic characteristics of the population because such information is lacking or inadequate. Thus, most samples obtained in the end are biased.

the problems encountered in drawing a random sample include:

(i) No officially recognised census of population; (ii) No other listings that can serve as sampling frames; (iii) Incomplete and out-of-date telephone directories; and (iv) No accurate maps of population centres. Hence, no cluster (area) samples can be made. Street maps are unavailable and streets are unidentified and houses are not numbered.

d) Language and Comprehension

In many countries, different languages are spoken in different areas. Thus, the questionnaire has to be in different languages for use within the same country. For example, in India, fourteen official languages are spoken in different parts of the country, while most governments and business affairs of many countries are conducted in English.

Similarly in Switzerland, German is used in some areas and French in others. Unfortunately, translating a questionnaire from one language to another is far from easy. In the translating process, many points may be left out entirely, because many idioms, phrases and statements mean different things in different cultures. For example, a Danish executive observed that meanings could change when translated and retranslated back to its original language. In this case, in a statement that was originally written in English and then translated into Danish, and finally translated back into English by a different translator, the statement changed from: "out of sight, out of mind", to "invisible things are insane".

Marketers use two basic methods to help overcome translation errors: forward translation and back translation

(i) Forward Translation In the case of forward translation, a single translator or group of translators prepares a translation from the source language into the target language. Several versions can be prepared and then they are compared. This approach is subject to the risk that the translation may contain errors and not accurately represent the meaning of the original or "source" questionnaire. Difficulties encountered in finding equivalent words or phrases in the target language may result in errors.

(ii) Back Translation The back translation method is the best known and most popular method. Following this procedure, a questionnaire is translated from the initial or source language by a bilingual translator who is a native speaker of the target language into which the translation is being made. This version is then translated back into the original or source language by a bilingual translator who is a native speaker of that target language. The two versions are then compared in the source language to check for errors and the quality of the translation. This approach is useful in identifying translation errors and the competency of the translator.
