Introduction

This book examines how an agile usability evaluation for patient-centered eHealth inventions can be realized to foster usability evaluations in health care that are easy to implement and rapid to perform. This section provides background information on evaluating the usability of eHealth inventions, taking into account the iterative approach of software development, which is characterized by short iterations designed to optimize a part of a software. Traditional concepts of usability evaluation, such as user-based and expert-based usability evaluation methods, which are difficult to reconcile with the iterative approach to agile software development, are presented.
