Summative Method
What is the Summative Method in User Research?
The Summative Method in user research is an evaluative approach used to assess the overall effectiveness, efficiency, and user satisfaction of a product or system after its development or implementation. It focuses on measuring how well the final product meets predefined goals and user needs.
Synonyms: Summative Evaluation, Summative Assessment, Outcome Evaluation, Product Evaluation
How the Summative Method is Used in User Research
The Summative Method is typically employed at the end of a development cycle or after a product has been launched. Researchers use this approach to gather quantitative data and qualitative feedback about the user experience. Common techniques include usability testing, surveys, and performance metrics analysis.
Why the Summative Method is Important
The Summative Method plays a crucial role in user research by providing concrete evidence of a product's success or areas for improvement. It helps stakeholders make informed decisions about future iterations, marketing strategies, and resource allocation. This method also offers valuable insights for benchmarking against competitors and industry standards.
