Featured in this case study: Water, Qualitative, Deliberative focus groups
Our client, United Utilities, processes around 200,000 tonnes of sewage sludge each year. They wanted to understand customer preferences for the different environmental outcomes that new, alternative technologies can deliver. In particular, they wanted to identify customer preferences and priorities and understand the acceptable trade-offs found between each technology. This posed a problem: the technologies were highly complex and unfamiliar to customers.
We designed a comprehensive qualitative and deliberative approach comprising of five three-hour discussions with groups of 16 customers. The core challenge for the research was presenting a set of unfamiliar and complex technology options to a lay audience in a way that allowed them to make confident, informed and meaningful judgements about each one. Prior to the sessions, the DJS Research team spent time with our clients bioresources team, developing a suitably comprehensive knowledge of the issues and technologies at hand.
As part of the learning process, we produced a series of descriptions and our Creative Services team designed visual guides for each technology to help communicate the subject into concise, digestible segments. We also incorporated tactile elements including hardcopy boards, displaying technology pathways and even samples of various outputs from the treatment process. The key to the success of the sessions was undoubtedly their structure. The researchers took an iterative drip-fed approach that continually presented new information and tested its comprehension, gradually building a deep understanding of the topic among participants.
Subject experts from our client’s bioresources team were present at each session to answer questions from participants in an accurate and authoritative way. Throughout the session each new concept was supported by a range of tailor-made digital and physical stimuli, designed by our Creative Services team. The research provided strong evidence on the views of customers, and future bill payers' preferences, regarding our client's bioresource plan and preferred pathways.

At DJS Research, our researchers have a wealth of experience moderating qualitative research, putting research participants at ease and exploring experiences, attitudes and behaviours to unlock those ‘golden nuggets’ of insight.

We develop a bespoke approach to meet each client’s objectives, but some commonly used methods in our qualitative toolkit include:
We draw on behavioural science to understand why people do what they do, not just what they say they do. We go beyond a basic question and answer format to examine the all-important context for decision-making, for example spending time with participants at home, observing their day-to-day life or asking them to complete a diary. We consider the behavioural biases at play and apply relevant frameworks or models to guide our analysis and recommendations.
Ultimately, by uncovering and sharing real life stories and applying our knowledge of human behaviour, we deliver deeper insights that impact our clients’ decision-making.
