Throughout the program we have worked with multiple stakeholders, including current and potential users of the toolkit, employees, managers, and policy and practice partners, to continue to improve the program. We recently published a scientific article describing this user centred design process and how it was used to adapt the program to be ready for the national implementation trial. The article showcases the multiple people and multiple disciplines involved in developing and implementing a workplace health promotion program like BeUpstanding, including content experts, design thinking and interaction design, business and product development, software development, implementation science. The article also describes the multiple ways in which data were collected to inform the iterative adaptions, including through deep dive interviews, surveys, toolkit analytics, and ad hoc communication and feedback. The BeUpstanding Journey Map was developed to help users understand what was involved in the BeUpstanding program. As we wrap up the national implementation trial, we are busily applying the user centred design approach to build the next iteration of BeUpstanding. This approach ensures that the program meets…
