Omnichannel user test : from online research to point of sales

  • Just like a remote user test for a website or an app, users follow a scenario with several steps and objectives. Some of them are online, others are offline. They live their experience in real conditions, then they report it step by step.
  • The user had to look online for the closest shop to its place, go there, ask for information about its smartphone's repair, and then decide accordingly if it's ok to do the repair.
  • The user gives feedback about its experience, like accessibility and visibility of the shop, vendor's reception and efficiency, or the offer.
