Case Study

How HP engineers amazing experience through real-time customer feedback and telemetry

As one of the most innovative brands in the world, HP Inc. is making the voice of the customer a prominent component of the entire product development lifecycle – from early portfolio planning; through product development; install & use; and product support.

HP had always tracked satisfaction across its products, but they realized that semi-annual surveys weren’t as actionable as they could be. Often, when feedback was presented to the product teams, it was already out of date, not in sync with current product versions and didn’t fully answer “why”, and more importantly, “how” to act.

Read the case study and find out how HP obtains a comprehensive view of the end-to-end product experience for over 50,000 annually released product SKUs, with responses in over 40 languages, yielding new and deeper insights that guide key design decisions.
