Face-to-Face (F2F) interview is one of the most popular quantitative methods in both sociology and marketing. The essence of this method lies in conducting a survey with a respondent using a pre-designed questionnaire via the CAPI (Computer Assisted Personal Interviewing) method on electronic devices.

CAPI is the modern industry standard for personal interviewing, where the interviewer uses a tablet or smartphone instead of a traditional paper questionnaire. The interviewer reads the questions and response options aloud, recording the respondent’s choices directly into the device. The digital questionnaire is programmed with built-in logic and skip patterns to ensure data accuracy and flow.

Advantages of the method:

• Elimination of errors (logical control): The software automatically monitors transitions between questions and filters.
• Errors that are possible when filling out paper questionnaires are completely eliminated.
• Multimedia capabilities: We can show respondents audio and video clips, packaging designs, or advertising banners directly on the tablet screen, which is critical for marketing tests.
• Quality control and geolocation: The system records the exact start and end times of the interview, as well as the GPS coordinates of the survey location. This guarantees 100% reliability of fieldwork.
• Instant data transfer: Data is entered into a shared database immediately after the interview is completed. This allows us to start analyzing it in SPSS or Excel without a lengthy manual data entry stage.
• Convenience for the respondent: The electronic format makes the survey process more dynamic, modern, and less tedious.

Erfolg Consult provides a full cycle of CAPI research: from programming complex questionnaires to providing analytical reports based on “clean” and verified data.

CAWI (online surveys) is an interactive data collection method in which respondents fill out a questionnaire themselves by clicking on a special link. This format is ideal for quickly studying the opinions of Internet users, evaluating advertising creatives, and deeply segmenting audiences. Online research provides the opportunity to conduct virtually all types of traditional research at minimal cost and in a short period of time, as well as to use new and non-standard methods.

Advantages of the method:

• Scale and speed: We can reach thousands of respondents in different regions and countries simultaneously. Data is received in real time, which significantly reduces the project implementation time.
• Visual interactivity: The online format allows you to integrate photos, videos, audio materials, and interactive elements into the survey. This makes testing logos, videos, or product concepts as visual as possible.
• Sincerity of responses: The absence of an interviewer reduces the “social desirability” effect. Respondents feel more comfortable answering sensitive or personal questions in an environment that is convenient for them.
• Automatic quality control: Software algorithms filter out inattentive participants (speeders) and check the logic of responses directly during the questionnaire completion process.
• Ease of access: The questionnaire is perfectly adapted to any device—smartphones, tablets, or computers. Respondents can take the survey at any time.

Erfolg Consult takes care of the entire process: from programming the complex logic of the questionnaire to selecting the target sample and conducting an in-depth analysis of the data sets obtained.

Erfolg Consult has proven experience in conducting mystery shopping research in industries such as banking, retail, and healthcare. This experience allows us to adapt our approach to assessing customer service quality in other industries.

How this method benefits your business:

• An objective outside perspective: You get an honest picture of how employees actually behave when management is not present.
• Monitoring compliance with standards: Checking compliance with sales scripts, politeness, cleanliness of the location, and adherence to service timing.
• Sales skills assessment: We analyze how effectively staff handle objections, offer additional products (cross-sell), and fight for customer loyalty.
• Competitor analysis: This method allows you to compare your service with that of your competitors, identify their strengths, and find areas for growth.
• Evidence base: Each check is accompanied by a detailed questionnaire and, upon request, an audio recording of the visit, photos of receipts, or photos of the storefront.

At the end of the mystery shopping project, our company provides a detailed analysis report that includes practical recommendations for addressing weaknesses. We also provide a detailed description of the mystery shopper’s visits along with audio recordings. This analysis report will help you understand what decisions are necessary to improve the quality of your services.

is an inventory of the entire retail network “in the field.” Our specialists walk every street in a selected district or city to record every active retail outlet. This provides a realistic picture of the market, which often differs from official statistical reference books.

What Retail Census offers your business:

• Up-to-date database: You receive an accurate register of retail outlets with addresses, types (supermarkets, kiosks, pavilions, etc.) and their exact GPS coordinates.
• Distribution potential assessment: The method allows you to see “white spots” on the map — areas where your product is not yet represented but where there is sales potential.
• Retail classification: We segment retail outlets by format, retail space, availability of special equipment (refrigerators, shelving), and customer traffic intensity.
• Market share analysis: You will learn not only the total number of outlets, but also the share of those where your product category or competitors’ products are already represented.
• Logistics optimization: Precise coordinates and classification of outlets help to build the most efficient routes for sales representatives and freight forwarders.

How Erfolg Consult does it:

• Field survey: Our sensors physically survey the territory, without missing a single point.
• Photo recording and GPS: Each record is confirmed by a photo of the facade and an accurate geotag in the system.
• Digital processing: Data is instantly aggregated into a database, eliminating duplicates and manual entry errors.
• Analytical visualization: Based on the census results, we provide not just a table, but an interactive map and a detailed report on the retail structure.

When we recommend Retail Census:

• When a brand enters a new regional market.
• To audit the work of your own distribution service.
• When you need to update outdated customer databases.

Erfolg Consult transforms the chaos of the market space into a clear and understandable structure for your growth.

Qualitative research can reveal people’s true motivations and hidden needs. The analysis is based not on statistical figures, but on open-ended responses and discussions on the research topic.

Based on the results of the research, you can find the best solutions for adapting your products, services, and brands to the needs of your target audience. We use the following methods to conduct qualitative research:

Focus group discussion is one of the qualitative research methods used for a more detailed and in-depth study of the target audience. It is a moderated discussion in a small group (usually 6–10 people) selected according to strict criteria. Unlike questionnaires, this method allows participants to interact with each other, argue, and share associations, which reveals deep insights that cannot be obtained through individual surveys.

The purpose of such group interviews is to determine the social mood, the attitudes of participants towards pressing issues, and their reasons and motives. Conducting a full-cycle study using the focus group method includes: renting a venue for focus group discussions, developing a guide, recruiting respondents, moderation, transcription, and an analytical report.

In-depth interviews – qualitative method of obtaining information, where there is direct contact between the respondent and the moderator. The conversation is both free-form and structured. In-depth interviews are necessary in cases where it is necessary to reveal the respondent’s opinions, attitudes, positions, and personal preferences in depth. The format of a confidential one-on-one conversation allows for the most detailed study of the respondent’s personal experience, beliefs, and hidden motives. Unlike questionnaires, there are no answer options here — only a live search for meaning.

Our specialists will professionally prepare a guide for in-depth interviews, taking into account your research objectives. An independent recruitment of respondents from your target audience will be conducted. Experienced moderators will professionally conduct in-depth interviews. All audio recordings will be transcribed into text, after which a substantive analysis will be compiled by our experienced analysts.

Expert interview is qualitative research method consisting of a series of in-depth conversations with recognized opinion leaders, industry experts, and representatives of government or public organizations. This format provides access to unique insights, forecasts, and “inside” expertise that is not available to the average consumer. Experts have a broad view of the market, knowledge of hidden mechanisms, and an understanding of promising trends. This method allows you to assess the viability of innovations, predict changes in legislation, or forecast the development of the industry for years to come. Experts help confirm or refute your project’s hypotheses based on their many years of experience and professional authority.

We take on the most difficult stage of recruiting experts (niche specialists, top managers, scientists), preparing specialized guides for conversations, and conducting interviews on an equal footing. The result is an expert analytical report with an in-depth interpretation of the data obtained.
