Exploratory, Confirmatory, Evaluative Research

Exploratory Research

Exploratory research is used to investigate and gain a deep understanding of users, their needs, behaviors, and the context in which they use a product or service. It is typically conducted at the early stages of the design process when the problem space is not well-defined. This type of research is typically open-ended and flexible, aiming to explore new areas of interest and generate insights that can inform future research.

Key Objectives:

• Discover potential user problems, needs, and desires that may not be immediately obvious.

• Generate Ideas and hypotheses about how a product or service could meet user needs.

• Inform design decisions by understanding the broader context in which users operate.

Example: Discovering new features for a fitness app through user interviews, feedback analysis, data mining, surveys and focus groups.

Confirmatory Research

Also known as hypothesis-testing research, involves testing specific hypotheses that we have formulated based on existing theories or assumptions based on prior exploratory research. This type of research is structured and focused, typically using quantitative methods.

Key Objectives:

• Test hypotheses that were developed during exploratory research or based on existing theories.

• Validate whether certain design decisions or product features effectively address user needs.

• Provide evidence to support or refute design choices before full-scale development or launch.

Example: Testing if social features in a fitness app increase user engagement and satisfaction by comparing an experimental group with a control group or conducting an A/B testing, statistical analysis.

Evaluative research

Evaluative research is conducted to assess the usability, effectiveness, and overall user experience of a product or service. It is typically carried out once a product is more fully developed or after a significant update to measure how well it meets user needs.

Key Objectives:

• Assess usability by observing how users interact with the product and identifying any pain points or issues.

• Measure satisfaction to determine how users feel about the product and its features.

• Identify areas for improvement to enhance the product's usability and user experience.

Example: Conducting usability tests on a new checkout process in an e-commerce app to identify any friction points and gather feedback on user satisfaction.

Key differences:

Exploratory Research: Used early in the design process to discover and understand user needs, behaviors, and the context of use. It is open-ended and qualitative, aiming to generate ideas and inform design directions.

Confirmatory Research: Conducted after hypotheses or assumptions have been made, this research tests these hypotheses to validate design decisions. It is structured, often quantitative, and provides evidence to support or refute ideas.

Evaluative Research: Performed to assess a product's usability and effectiveness, typically after development or during the refinement stages. It focuses on identifying issues, measuring satisfaction, and guiding improvements.
