The CEO of HAO2 believes that ongoing stakeholder involvement is necessary to achieve effective and profitable products. To enable the inclusion of those who may be excluded from common engagement methodologies (e.g., focus groups), the company uses a wide range of engagement methodologies, such as instant chat, video chat, surveys and interviews. For the 3DNovations Hub, HAO2 conducted a feasibility study, together with a university, an NGO and a governmental organisation, and a pilot with a city council, governmental organisation and a school for young children with special needs.
