A number of companies were contacted over a period of several weeks via e-mail
or through contact forms on companies’ homepages. The author was referred to
Elematic’s marketing manager by another interviewee. The aim of the study was
explained and the company’s willingness to participate was inquired. Many
refusals were received or companies did not respond at all. The four companies
which are part of this thesis were the ones that agreed to an interview.
The data was collected through interviews and e-mail interviews. Molli Nyman
and Päivi Talonen were interviewed in person, whereas e-mail interviews were
conducte with Sandya Lang and Interviewee X. This was done out of
convenience and Interviewee X chose e-mail interview because he wanted to
answer the questions together with someone from the sustainable development
department.
