Rapid prototyping creates quick preliminary versions of a product or deliverable, then iteratively refines them. In analytics, data-powered apps support this process by enabling early stakeholder feedback before substantial development effort is committed. section 12.2.1
A practical prototyping workflow can:
- Create an interactive preliminary deliverable when complex user input or custom code exceeds a visualization tool’s capabilities. section 12.2.1
- Collect stakeholder feedback during development to clarify the final product’s required form. section 12.2.1
- Use R Shiny or Streamlit to build interactive prototypes, reports, and dashboards from analysis code. section 12.2.1
Interactive prediction app
An interactive Streamlit app predicting rat sightings illustrates how a data-powered application can serve as a concrete prototype for a custom analytical deliverable. section 12.2.1
