Three Steps to Insight

1
Design Your Study
Pick an industry, define attributes and levels, choose Rating-Based or ACBC methodology, add optional demographic questions, and generate profiles โ€” through a guided step-by-step wizard.
2
Collect Responses
Share your survey link. Respondents rate product profiles on a 1โ€“10 scale (Rating) or go through Build-Your-Own โ†’ Screening โ†’ Choice Tournament (ACBC). Track responses in real time.
3
Read Your Report
A 12-tab interactive report is generated automatically โ€” from executive summary to market simulation. Every section includes plain-language interpretation guides so you can understand results without prior training.

Beyond the Report

The survey report is the core output, but VASAAPPS also includes tools for managing respondent quality, segmenting audiences, and running classroom-based teaching workflows.

๐Ÿ› 
Design Builder
Guided wizard: choose from 6 industries, configure up to 9 attributes ร— 7 levels (tier-dependent), pick Rating-Based or ACBC methodology, add demographic questions, and generate orthogonal profiles automatically.
๐Ÿ“‹
Live Survey Engine
Share a link and collect responses. Rating-Based surveys use a 1โ€“10 profile rating scale. ACBC walks respondents through three adaptive phases: Build-Your-Own, Screening (with must-have/unacceptable detection), and a Choice Tournament bracket.
๐Ÿ“Š
Segment Comparison
Create custom respondent segments or auto-segment by any demographic field. Compare conjoint results across groups โ€” see which attributes matter more to one segment versus another, and uncover hidden preference heterogeneity.
๐Ÿ›ก
Quality Audit
Automatically flags straight-liners, speeders, extreme-only raters, and other suspicious patterns. Each respondent gets a quality score (Good / Suspect / Poor) with a summary dashboard showing total, good, suspect, poor counts and average score.
๐Ÿ“š
Classroom
Teachers create classes with auto-generated join codes, enroll up to 8 students per class, assign conjoint studies, monitor progress, and provide grades and feedback. Students join with a code and see their work, class info, and instructor comments in one view.
๐Ÿ‘ฅ
User Management
Admin dashboard with summary cards (total users, designs, responses), bulk user creation via CSV, tier management (Free / Starter / Academia / Professional), and a security log tracking all authentication and access events.

12 Report Tabs, Fully Interpreted

Every tab includes built-in “What This Means” boxes, color-coded legends, and worked examples โ€” designed so you can read the results even if you have never taken a course in survey design or data interpretation.

Executive Summary

Key metrics at a glance

Your starting point. A dashboard-style overview with summary cards showing model fit, number of respondents, attributes tested, and the most important findings. Designed to give you the big picture in seconds before drilling into specifics.

Relative Attribute Importance

Which features drive customer decisions the most

Each attribute gets a percentage showing its weight in the decision. If Price shows 40%, it accounts for 40% of preference variation. Includes a color-coded legend โ€” High (>30%) means a critical differentiator, Medium (15โ€“30%) a competitive advantage, and Low (<15%) nice-to-have.

Part-Worth Utilities

Preference scores for every attribute level

Utilities are “preference points.” One level per attribute is the baseline (zero). Positive = preferred more, negative = preferred less. The report includes a worked example: “If Premium Brand = +2.5 and Generic = โˆ’1.2, customers prefer premium by 3.7 points โ€” a strong preference.” Per-attribute bar charts and tables with a built-in “Understanding Utilities” guide.

Interaction Effects

How attributes influence each other

Tests whether the effect of one attribute depends on the level of another โ€” for example, whether brand preference changes at different price points. Helps you spot combinations that are worth more (or less) than the sum of their parts. Available on Academia and Professional tiers.

Attribute Trade-off Analysis

Substitution ratios & resource allocation

How much of one feature are customers willing to give up to get more of another? Calculates marginal substitution ratios between attributes and translates abstract utility numbers into practical guidance for product configuration and resource allocation.

Swap Preference & Mental Accounting

Compare two changes and see their price impact

An interactive tool. Pick “Change A” (e.g., Brand X โ†’ Brand Y) and “Change B” (e.g., standard โ†’ premium material), compare utility differences side by side. If a price attribute is present, both changes get translated into dollar equivalents โ€” so you can say “this brand switch is worth a $15 price drop.” Includes baseline price sliders for each side.

Demographic Profile

Respondent breakdown & distribution

If your survey includes demographic questions, this tab shows respondent breakdown โ€” age groups, gender splits, income brackets, or whatever custom demographics you defined during study design. Visualized as distribution charts so you can verify your sample composition before interpreting conjoint results.

Market Simulation

Four scenario types + disruption analysis

Define competing products and predict real-world outcomes. Four built-in scenarios: Competitive Market Share (how products compete), Product Mix & Inventory (optimal quantities from demand), What-If Scenarios (test hypothetical configs), and Portfolio Optimization (maximize market capture). Plus a Disruption Simulator: add a new entrant and see exactly which products lose share, with before/after pie charts and a detailed impact table. Includes a “What is Market Simulation?” guide and “Understanding the Results” boxes.

Product Optimization

Ideal configuration & strategic pricing

Automatically identifies the product configuration that maximizes customer preference. Shows the ideal level for each attribute and provides strategic pricing guidance โ€” not just what customers want, but how to position and price it.

Willingness-to-Pay

Price sensitivity, brand equity & WTP per feature

Converts utility values into dollar amounts. How much would customers pay for each feature upgrade? What is the brand equity in monetary terms? Maps price sensitivity across all attribute levels. Requires a price attribute with numeric levels in your design.

WTP to Switch

Switching cost between product configurations

Compare two full product configurations and calculate the implied switching cost โ€” the price difference needed to make a customer indifferent between them. Useful for competitive pricing, upgrade bundling, and estimating how much it costs a competitor to poach your customers.

Model Diagnostics

Technical quality & data health

The technical layer: log-likelihood, convergence status, estimation method details, and per-respondent raw data. Export responses to CSV (Academia and Professional tiers) for further analysis in R, Python, or Excel. For researchers and instructors who want to verify the statistical foundation.
