Immediately after purchasing the "To Go" offer, you will get access to my member area, where you can book an appointment in my calendar under the first milestone "Kickoff Call". The purpose of the kickoff is for us to get to know each other briefly, clarify the general conditions and set the dates. The whole thing takes about 30-45 minutes.

In the briefing workshop, you, your team and I will define the research objectives and discuss the criteria for selecting the interview participants. The workshop lasts between 45 and 60 minutes.

According to your criteria, I recruit suitable interview participants with my partner Testing Time. Depending on the screening criteria, this takes approx. 1-3 days. During this time, I draw up the interview guidelines and set up the necessary infrastructure.

Then it's time for the interviews to take place. The interviews usually happen in one day. If interviewees from the USA are participating, it may also be spread over several days due to the time lag. I conduct the interviews via Zoom so that team members can participate as "silent listeners".

Then it's crunch time. I get down to the precise evaluation of the interview notes and the preparation of the final report. I identify patterns in the customers' statements and try to establish the connections between all the statements to give your organization the insights it needs to make fact-based decisions

And finally, we will all come together again for a one-hour insight workshop in which I will present the outcomes and discuss the conclusion and possible next steps with you.

"Screening criteria" in the context of customer interviews refer to the set of characteristics or requirements used to select participants for the interviews. These criteria are designed to identify potential customers who are most relevant to the study, ensuring that the interviewees represent the target market or specific customer segment of interest. The criteria might include factors like demographics, purchasing behavior, product usage, or any other attributes relevant to the research objectives, helping to ensure that the feedback and insights gathered are pertinent and valuable.

The recruiting cost of testing time varies primarily due to differences in the complexity of participant requirements, the scarcity of the target demographic, and the incentives needed to attract participants. Complex criteria or niche target demographics can make it harder to find suitable participants, thus increasing recruitment efforts and costs. Additionally, if the testing requires specialized knowledge or skills, higher incentives may be necessary to encourage participation. Market demand, the length of the testing sessions, and logistical considerations (like location and timing) can also influence the overall cost. In essence, the more specific or demanding the testing requirements, the higher the recruitment costs are likely to be.

Testing Time calculates the recruiting costs based on the specified screening criteria. The more criteria and the more specific the selection of candidates, the more expensive. With 2 to 3 criteria you can calculate with CHF 600 to CHF 900.

No. The special "to go" price is calculated with 7 participants.

Yes, as long as the participants correspond to the target group and do not exceed the number of 7. The costs are then reduced by CHF 600, which will be refunded at the end of the project.

The principle that 7 interview participants can deliver relevant insights in user interviews is grounded in the law of diminishing returns, specifically in qualitative research, as popularized by usability consultant Jakob Nielsen. This concept suggests that after interviewing about five to seven users, you tend to notice a pattern where no substantially new information is gained from additional participants. The majority of usability issues or insightful themes tend to emerge within this range of interviews, as the same points or problems are repeatedly observed. Beyond this number, new insights become increasingly rare, making additional interviews less cost-effective and more time-consuming without adding significant value. This efficiency makes 5-7 participants a practical standard for gaining meaningful insights without unnecessary resource expenditure.

Since it is important to understand the subtleties of the customer's statements and to be able to read between the lines, I only conduct interviews in languages that I really master at a high level: Swiss German, High German, English and Hebrew.

Each interview session is scheduled for one hour. This includes a short "icebreaker", the main part and a summarizing conclusion. If interviewees are particularly communicative and their statements are of high value, I will never cut an interview session short, no matter how long it takes.

Yes, very welcome, if there are a maximum of two additional participants. The only condition is that the webcams and microphones are turned off during the entire interview, as candidates often feel intimidated if too many "interrogators" talk at them. 

Recording interviews under GDPR adds complex compliance requirements, such as securing explicit consent, ensuring data protection, and managing increased data handling responsibilities. These factors can deter participant willingness, add significant resource burdens, and pose potential privacy risks. That's why I relay on methods like detailed note-taking, which can effectively capture the interview insights without the GDPR-related complexities and risks, ensuring both efficiency and compliance.

Yes, Testing Time provides the option of uploading an NDA to the portal when recruiting candidates, which participants must sign before the interview in order to be accepted at all.
