The decision
A broadband team tests speed, installation fee and support hours. In an illustrative choice model, 200 Mbps adds 0.6 utility, weekend support adds 0.4, and a ₹500 installation fee costs 0.7. These are teaching assumptions.
Which bundle merits a field test, and how would you check the measurement?
Worked solution
Reveal the visual and solution
- Build balanced choice tasks with realistic profiles and a no-purchase option. Hold back tasks for validation and separately collect perceptual ratings of alternatives.
- Relative to the base, the full bundle adds 0.6 + 0.4 − 0.7 = 0.3 utility. Speed and support with no fee would add 1.0, but compare actual delivery and acquisition costs.
- If modelling trust and adoption intent, validate their separate indicators before estimating structural paths. Test real signups and avoid turning utility or an association into a sales forecast or causal claim.
