Maximum difference scaling (max-diff) analysis for a Lactam insurance provider

  • Identified top value drivers for insurance plan selection

  • Prioritised feature upgrades based on customer importance ratings

  • Improved plan uptake by 17% across target LatAm markets


CLIENT CHALLENGES

  • A Latin American insurance firm aimed to revamp its health insurance offerings to align better with changing customer expectations
  • The client needed to identify which features mattered most to different consumer groups across Brazil, Mexico and Columbia
  • With limited flexibility on pricing, the client wanted to optimise bundles to drive higher plan adoption and retention rates

OUR APPROACH

  • Step 1: Data collection
    • Designed and deployed an online survey targeting 4,500 recent and prospective customers

    • Included a max-diff module to measure the relative importance of 15 possible insurance features

  • Step 2: Survey setup
    • Each respondent evaluated sets of five features, selecting the most and least important from each set

    • Demographic, purchase history and plan tenure data were also collected

  • Step 3: Data processing
    • Cleaned the dataset, removing low-engagement responses (straight lining, inconsistent answers, etc.)

    • Created standardised feature labels across Spanish and Portuguese survey versions

  • Step 4: Max-diff analysis
    • Used hierarchical Bayesian estimation to calculate utility scores for each feature at the respondent level

    • Aggregated results, to determine overall feature importance and market-level priorities

    • Identified feature preference splits by country (Brazil, Mexico, Columbia) and by key customer segments (e.g., younger buyers, high-value clients)

IMPACT DELIVERED

  • Helped the client design three upgraded plan packages prioritising high-importance features
  • 17% increase in new plan subscriptions during pilot market tests
  • Enabled more targeted marketing messaging emphasising telemedicine and mental health support
  • Supported pricing justification by aligning upgrades with customer-perceived value
