Harold was among the first professionals forging a path for design in the technology industry. He co-founded Electronic Ink, the first technology-design firm dedicated exclusively to the human-centered design of software, and attracted landmark projects, including operating systems, early banking machines, medical record systems, and financial services platforms. Over thirty years of designing enterprise systems, Harold extended the voice and impact of design beyond software user interfaces. Recognizing a need for improved collaboration among the diverse disciplines inside business enterprises led to the development of operations modeling: human-centered design research informing the creation of models articulating the relationships, risks, and opportunities among the enterprise’s human context, business processes, technology, and data. Harold is the author of Wrench in the System, published by John Wiley & Sons. He has taught courses at various universities and has lectured at conferences around the world. Harold served as an expert in design and technology for international legal proceedings. He received the Alumni Achievement Award from Carnegie Mellon University for significant contributions to the design and technology industries and is a member of the Advisory Board of CMU’s College of Fine Arts.
