Description of the components in the development process and data collection.

Component in the development process	Group of participants and number of individual interviews (n) or focus groups (FG)	Content
1. Individual interviewsa	Health care professionals (n=13) People with COPDb (n=6) / relatives (n=2)	Semistructured interviews with health care professionals and people with COPD and their relatives.
2. Identification of touch points from individual interviews	Intermediate work by the researchers	Identification of touch points (ie, topics that seemed crucial or were mentioned by several of the interviewees).
3. Focus group discussionsa	Health care professionals (FG=2) People with COPD and their relatives (FG=2)	The identified touch points and self-management strategies that were highly prioritized in the National Guidelines for COPD were presented to the participants. The participants were encouraged to reflect on the topics that were presented and particularly on how an electronic health (eHealth) tool could facilitate provision of, or give support for, such self-management strategies.
4. Development of mock-ups for the eHealth tool and pilot videos in line with wishes from focus group discussions	Intermediate work by the researchers	Based on the wishes and needs expressed during the individual interviews and focus group discussions, mock-ups for the website and pilot videos were developed showing breathing techniques for stair climbing and muscle strength training.
5. Focus group discussionsa	Health care professionals (FG=2) People with COPD and their relatives (FG=1)	The mock-ups and the pilot videos were presented. The participants were encouraged to reflect on the basic structure, the colors, wordings, and how well the pilot films served their purpose. Moreover, the participants were asked to reflect on how the website could be introduced to people with COPD and how the use of the website should be followed up.
6. Focus group discussionsa	External researchers (FG=1)	Based on their scientific knowledge about COPD, the external researchers were encouraged to identify and reflect on important interventions and self-management strategies that would be important to include on the website.
7. Focus group discussionsa	External researchers (FG=1)	A summary of the suggestions, wishes, and needs brought up by the health care professionals and people with COPD and their relatives were presented. The researchers were asked to reflect on how the interventions and self-management strategies should be presented considering both scientific correctness and the need to allow for adaptations to local conditions. Moreover, the researchers were asked to prioritize between the suggestions, wishes, and needs.
8. Development of prototype for the eHealth tool	Intermediate work by the researchers	A prototype for the eHealth tool was developed based on input from the individual interviews and focus group discussions. The iterative tests (9) led to further development.
9. Iterative tests	Health care professionals (n=6) People with COPD (n=6)	Iterative tests focusing on what words to use in the menu structure and the navigation of the website were performed.
