Plan-Evaluate-Deliver (PED): A new framework for heuristic UX evaluation

Usability professionals have widely accepted and applied heuristic evaluation since the 90’s. In the last twenty years, the digital context changed a lot, and usability expanded to UX. The evaluation methods should adapt to these changes. That is the main motivation to develop the Plan-Evaluate-Deliver (PED) framework.

Heuristic evaluation is basically an expert review of digital systems; it’s low-cost and fast, hence quite popular in the industry. PED provides a structured, step-by-step framework for heuristic evaluation practices. The framework is based on research studies and industry applications, and it addresses debated inadequacies of the conventional heuristic evaluation methods. This talk will be the first presentation of PED to UX community and will walk the audience through the steps of the framework.

PED is expected to enable UX professionals to detect UX problems more effectively and to offer better improvements for digital systems.
