Client: Greenfields Research (on behalf of City of Cape Town)

Industry: Research 

Specialty: Mixed Methodology Research

The Challenge: Expanding Research Reach and Engagement

Greenfields Research, traditionally focused on quantitative research through catch-up work and email-based surveys, faced the common challenge of competing for respondents' attention in an increasingly crowded digital landscape. Traditional research methods were limited by geographical constraints and time-intensive field work. The company needed a solution that could provide qualitative richness while reaching a broader geographical audience more efficiently.

The Solution: Yazi's WhatsApp Integration and AI Interviewer

Step 1: Leveraging WhatsApp's Universal Presence

Yazi's integration with WhatsApp provided Greenfields access to a platform that commanded unprecedented attention across all audience segments. Unlike emails or phone calls that often go unanswered, WhatsApp offered a familiar and engaging environment where respondents were more likely to participate and share their thoughts openly.

Step 2: Implementing Dynamic Discussion Guides

The AI Interviewer enabled Greenfields to conduct conversations that went beyond static questionnaires. The platform allowed for:

  • Core questions presented in a conversational manner
  • Dynamic adaptation of follow-up questions
  • More natural and open dialogue with participants

Step 3: Utilising Voice Notes for Rich Qualitative Data

The platform's ability to accept and automatically transcribe voice notes provided an additional dimension to data collection, allowing respondents to share more detailed and nuanced responses than traditional text-based methods would permit.

The Results: Rapid Insights with Qualitative Depth

"The established techniques we had been in field for about three weeks and with Yazi, we were able to create our questionnaire launch and get feedback within a 24-hour cycle... Here you're able to get a very good sense very quickly about what works or what doesn't work or what types of things may need further investigation."
