Conjoint Analysis Services – Measure Consumer Preferences With Precision

Unlock the trade-offs your customers make. Our Conjoint Analysis Services turn complex consumer choices into actionable insight, enabling confident decisions on pricing, features, packaging, and positioning. Research Bureau delivers robust quantitative research and statistical analysis that predicts preference, willingness to pay, and market share with scientific precision.

What is Conjoint Analysis and why it matters

Conjoint analysis is a statistical technique that quantifies how consumers value individual product attributes and combinations of attributes. Instead of asking respondents what they want, conjoint methods observe trade-offs—mirroring real-world purchase decisions. This yields predictive utility scores (part‑worths) and market simulations that convert preferences into expected behavior.

• Use conjoint to set prices that maximize revenue.
• Use conjoint to choose feature bundles that increase adoption.
• Use conjoint to forecast market share for new product concepts.

When you need reliable answers to "Which features matter most?" and "What price will the market accept?", conjoint provides the empirical foundation.

Our conjoint methodology — rigorous and customizable

We design and execute conjoint studies using modern best practices. Every project follows these core phases to ensure scientific rigour and business relevance:

1. Problem definition and attribute selection

   • Workshop with stakeholders to prioritise objectives.
   • Qualitative prework (focus groups or intercept interviews) to generate attributes and realistic levels.

2. Experimental design

   • Choice of method: Choice-Based Conjoint (CBC / DCE), Adaptive CBC, Full-Profile conjoint, or MaxDiff for attribute importance.
   • Efficient design construction (D‑efficient or Bayesian designs) to maximise information per respondent.

3. Survey programming and QA

   • Responsive online instruments with randomisation and attention checks.
   • Pilot testing and iteration to ensure respondent comprehension.

4. Fieldwork and sampling

   • Representative or targeted quotas (demographic, behavioral, purchase history).
   • Quality controls: speeders, straightliners, IP and device checks.

5. Estimation and analysis

   • Models: Hierarchical Bayes (HB), Mixed Logit, Latent Class, or Multinomial Logit, depending on goals.
   • Derive part‑worth utilities, willingness‑to‑pay, elasticities, and segmentation.

6. Market simulation and scenarios

   • Share of preference models, “what-if” scenarios, and revenue simulations.
   • Sensitivity analyses and confidence intervals.

7. Delivery and decision support

   • Actionable report, executive summary, interactive dashboards, and workshop to translate findings into strategy.

Conjoint types — which approach is right for you?

Choosing the right conjoint design is critical. Below is a comparison of common approaches to guide selection.

Method	Best for	Pros	Cons
Choice-Based Conjoint (CBC / DCE)	Purchase-like decisions, market share forecasting	Closest to real choice; scalable; compatible with HB	Requires sufficient sample size; design complexity
Adaptive CBC	Detailed individual-level utilities with fewer tasks	Personalised tasks; improved respondent engagement	More complex programming; longer field time
Full-Profile Conjoint	Simpler designs with few attributes	Easier to explain to respondents; suitable for small attribute sets	Not scalable for many attributes; less realistic for complex choices
MaxDiff (Best‑Worst Scaling)	Prioritising a long list of attributes or benefits	Robust ranking of many items; efficient	Not suited to feature trade-off simulations
Choice Modeling with Price (DCE)	Price sensitivity and WTP estimation	Directly estimates price trade-offs; supports revenue models	Requires realistic price levels; design care needed

If you’re unsure which approach suits your objective, share your brief and we’ll recommend the optimal design.

Technical capabilities — models and tools we use

We apply industry-standard and advanced statistical techniques depending on project complexity:

• Hierarchical Bayes (HB): Individual-level utilities with shrinkage to population priors.
• Mixed Logit / Random Parameters Logit: Captures random taste variation and correlation across attributes.
• Latent Class Analysis: Identifies discrete segments with distinct preference structures.
• Bayesian MCMC estimation: For robust interval estimates and uncertainly quantification.
• Willingness-to-pay (WTP) estimation: Translate utilities into monetary values.
• Market simulators: Logit share, First Choice, Randomized First Choice for revenue/market share forecasting.

We implement analyses using Sawtooth, R (bayesm, mlogit, rstanarm), Python (PyMC, scikit-learn), and custom scripts for bespoke solutions.

Sample size and precision — how many respondents do you need?

Sample size depends on design complexity, number of attribute levels, and the level of precision required. Below is a practical guideline.

Project goal	Typical minimum sample	Notes
High-level market share estimation	300–500	Adequate for aggregate results and basic segmentation
Individual-level utilities (HB)	500–1,000	Enables reliable person-level inference and modelling
Deep segmentation (latent classes)	1,000+	Required to identify stable segments and profile them
Niche B2B / small target	100–300	Use targeted panels and careful design; consider adaptive tasks

We always calculate power and precision for your specific design and provide a recommended sample plan in the proposal.

Example case study (anonymised)

A consumer electronics client needed help choosing between three feature bundles and a pricing strategy for a new smartphone.

• Attributes: Price (R6,999–R12,999), Battery life (12h/18h/24h), Camera (12MP/48MP/108MP), Storage (64GB/128GB/256GB), Warranty (1yr/2yr).
• Method: CBC with Hierarchical Bayes estimation; sample 1,200 nationally representative smartphone shoppers.
• Key outputs:
  • Part‑worths revealed camera quality and price as the top drivers of choice.
  • WTP: Consumers were willing to pay ~R1,800 extra for 108MP over 12MP, and R950 for 256GB over 64GB.
  • Simulations showed a mid-tier bundle priced at R9,499 maximized projected revenue and captured 38% share against competitor profiles.
  • Latent classes identified a price-sensitive segment (34%) and a premium feature-seeking segment (28%).

Action taken: Client launched the mid-tier bundle, adjusted marketing messaging to highlight camera and storage, and created a targeted promotion for price-sensitive segments. Post-launch sales aligned closely with conjoint projections, validating the model.

Example: Part‑worth table and market share simulation

Below is a simplified example of estimated utilities and a logit share calculation for three product concepts.

Part‑worth utilities (example):

Attribute	Level	Utility
Price	R8,000	-1.20
Price	R10,000	-2.10
Price	R12,000	-3.00
Battery	12h	-0.40
Battery	24h	+0.80
Camera	12MP	-0.30
Camera	108MP	+1.00
Storage	64GB	-0.20
Storage	256GB	+0.60

Product utilities (sum of levels):

Product	Levels	Total utility
A	R8,000 + 24h + 12MP + 64GB	-1.20 + 0.80 -0.30 -0.20 = -0.90
B	R10,000 + 24h + 108MP + 256GB	-2.10 + 0.80 +1.00 +0.60 = 0.30
C	R12,000 + 12h + 108MP + 256GB	-3.00 -0.40 +1.00 +0.60 = -1.80

Logit probability (exp(U) / sum exp(U)):

Product	Utility	exp(U)	Share
A	-0.90	0.407	30.9%
B	0.30	1.350	51.4%
C	-1.80	0.165	6.3%
None / Outside option	0.00	1.000	11.4%

This simplified calculation shows how utilities translate into predicted choice shares. Our full models include respondent heterogeneity, confidence intervals, and randomized-first-choice simulations for realistic purchase uncertainty.

Frequently asked questions (FAQs)

Q: How long does a conjoint study typically take?
A: Simple CBC studies can complete in 3–4 weeks; more complex HB or segmentation projects typically take 6–12 weeks depending on sample and approvals.

Q: Can conjoint measure willingness to pay?
A: Yes. When price is included as an attribute, utilities can be converted to WTP estimates. We provide robust methods for median and distributional WTP with confidence intervals.

Q: Do we need a representative sample?
A: It depends on goals. For national market forecasts, representative samples with quotas are essential. For niche or B2B studies, targeted panels are appropriate.

Q: Will you hand over raw data and code?
A: Yes. We supply anonymised raw data, codebooks, and (on request) analysis scripts for reproducibility.

Q: Can conjoint handle bundles and add‑ons?
A: Absolutely. Conjoint excels at evaluating bundles, optional features, and subscription tiers. We also model constraints and cannibalisation effects.

Common pitfalls — and how we avoid them

Poor outcomes often stem from avoidable errors. We proactively manage common pitfalls:

• Too many attributes or levels: We design efficient tasks and prioritise attributes to prevent respondent fatigue.
• Unrealistic prices: We ground price levels in market reality to obtain valid WTP estimates.
• Weak sampling: We implement quotas and quality controls to ensure meaningful inference.
• Ignoring heterogeneity: We use HB and latent class models to capture diverse consumer preferences.

Our methodological rigour ensures your decisions rest on reliable evidence.
