Paper and Pencil Interviewing (PAPI) is still the most commonly used method for data collection. It represents the process of personal interviewing where the interviewer has a printed questionnaire from which they read the questions to the respondent and fill in the answers.

PAPI requires well-trained interviewers, who, based on a good approach and communication with respondents, gather information about their attitudes, beliefs and opinions on a given research topic. It is a suitable method for closed-ended questions, e.g., multiple-choice questions as well as open questions. Personal contact with participants can result in richer and more detailed answers.

Computer-assisted telephone interviewing (CATI) is a research process of data collection through a telephone survey that is completed on a computer and which shortens the time required for the survey. The course and sequence of the questions asked to the respondent are predefined through a large number of filter options and depend only and exclusively on the answers given by the respondent to the previously asked questions. In this way, the possibility of an error that could occur when entering hand-made surveys is reduced.

This methodology, together with the advantages of licensed RM + CATI CLIENT software, available to the agency with 50 CATI units in its own CATI CALL centre, provides the ability to control the work of interviewers by supervisors during the survey process, thus providing complete control over the entire project.

A quantitative market research method in which a computer assists interviewers in surveying. A system containing a structured survey questionnaire is programmed for each CAPI survey. Based on the software system, the computer determines the next question during the survey based on the last answer of the respondent, which ensures complete control over the work of the interviewer and eliminates the possibility of omitting questions during the survey. Interviewer journals are also kept to control assigned routes and field steps when selecting respondents.

Compared to the PAPI (Paper and pencil interviewing) methodology, CAPI provides a significantly higher degree of reliability of the obtained data. The CAPI methodology enables the branching of questionnaires using a large number of software-defined filters. As such, the possibility of error is reduced to a minimum, data quality is improved and the costs incurred in PAPI methodology are reduced, which occur due to data entry and subsequent cleaning of the database.

Quantitative research method, which is conducted with the help of a computer, so that the respondent fills out an online survey posted on a website that is specially designed for that research.

Fast, reliable and accurate data collection is an advantage of online interviews. By filling in the questionnaire on the website, the respondent enters the data directly into the database, and no subsequent entry is required. The course and order of the questions is predefined through automatic filter options and depends on the answer given by the respondent to the previous questions. In this way, possible logical errors are prevented.

The advantage of this type of interview is the possibility of placing audio and visual materials (images, advertisements, logos) on the website, as well as the fact that it is not necessary to print questionnaires, use phones or other accompanying equipment, and the respondent has time and space to fill out an online questionnaire whenever they want, without pressure.

This methodology makes it much easier to collect data from remote geographical areas and it is easier to reach certain target groups (Internet users, employed population…)

All data entered automatically arrives to the main server, which enables monitoring of quotas, i.e., efficient monitoring of the sample during the process of data collection.

One of the tools we use in a very simple and, above all, economical way in order to conduct individual, customer-tailored, qualitative research.

According to the specific needs of the client, with a detailed research plan according to previously harmonized rules, trained mystery shoppers visit companies simulating one of the different client profiles (both based on verbal and non-verbal communication). From the first establishment of contact, they record all the elements of behaviour, which can give objective and comprehensive pictures of the company as a whole and the process that is the subject of the study.

In this way, clients are given the opportunity to peek into the work environment of direct competitors in a completely legitimate and inconspicuous way, but also to evaluate their quality of service and raise it systematically to a higher level.

One of the most effective ways to understand the reasons behind problem behaviours is in-depth analysis.

An in-depth interview is a technique of qualitative research that represents a conversation between two people, with the goal of deeper knowledge about human thoughts, feelings and behaviour on important issues. This type of interview is often unstructured, and therefore allows the interviewer to encourage the interviewee to talk about the given topic.

The most commonly used method of qualitative research, which is a discussion on a particular topic, and which takes place in an informal way in a group of 6 to 10 people gathered to express their opinions and ideas on a given topic. The group is led by an experienced moderator, who is specially prepared for a specific project. During the discussion, respondents provide a lot of information about their opinions, thought processes and beliefs, through the application of various projective and rational techniques.

The advantage of a focus group is the ability to encourage individuals to think more deeply and in more detail about their habits, beliefs, motives, and needs, as well as to study participants in a natural, everyday environment. There is a possibility of reaction and involvement of other participants in the group and direct interaction of researchers and participants, which is also an advantage of the focus group. Practice and research so far have shown that group discussion is more encouraging for people to spontaneously express their emotions and opinions.

The client can observe the discussion behind a one-way mirror in the focus study and communicate with the moderator during the focus group moderation.

Quantitative research that is conceptually designed to reduce research costs for the client. In this way, several different clients come together within one project, sharing the costs of organizing the process, which directly affects the reduction of the cost of research per client. The price of the survey is calculated by the number of questions and tends to decrease with the increase in the number of questions. A suitable method for research that is not time-limited.

PANEL represents a database of examinees who have consented to participate in the upcoming research projects by leaving their e-mail addresses and information about demographic characteristics. The respondents are usually invited to participate by e-mail, after it has been previously confirmed that they match the required profile, based on demographic and other characteristics defined according to the project task. Respondents are given the option of of participating in the research via computers, cell phones and tablets, and also, it is convenient for researching target groups of the population which use the Internet for daily activities.
