The Quality Assurance of Human Experience

While user testing tells us what this group of people thinks, heuristic evaluation tells us how the service measures up against universal principles of cognitive psychology and human-computer interaction (HCI). We audit the service against gold Standards, such as visibility of system status, error prevention, and aesthetic integrity.

The Strategic Value:

This is the safety net for your brand. It identifies silent killers that might not bother a single user in a test but will cause massive churn when scaled to millions. It ensures the service is architecturally sound before a single line of code is written.

The Expert Tip:

A heuristic audit isn’t a complaint list. For every violation found, provide a severity rating (0-4). This helps the engineering team triage their backlog, focusing on the catastrophic errors that are currently haemorrhaging brand trust.
