Flow Logic: Orchestrate Sophisticated Studies

A survey without logical branching is just a static form. High-quality research requires routing respondents down relevant paths based on their answers, avoiding fatigue and collecting precise data. Public-Op's Flow Logic engine provides clean, robust, and highly flexible branching rules that scale to any study depth.

Skip Logic and Block Routing

Define routing at the section, page, or question level. If a respondent is not familiar with a brand, seamlessly skip them past detailed competitor analysis blocks directly to the demographic section. This reduces respondent drop-off rates and increases overall survey completion quality.

IF familiarity == "Never heard of it" THEN
    SKIP TO section_demographics
ELSE
    SHOW competitor_analysis_block
    PIPE brand_name INTO question_2

Dynamic Piping and Placeholders

Inject answers from previous questions directly into subsequent ones in real time. If a respondent selects 'Product Design' as their favorite feature, OPScript and Flow Logic let you dynamically pipe that value into a rating grid: 'Please rate {favorite_feature} on the following criteria.' This creates a tailored, conversational survey experience.

Advanced Conditional Rules

Go beyond simple A/B paths. Flow Logic supports nested AND/OR operators, scoring-based branching (e.g. if the calculated sentiment score is negative, trigger a follow-up feedback block), and geolocation-based filters. This gives you enterprise-level programming power with next-generation developer tooling.
