I did read it, thus my comment. Did you actually read the methods? This is what you're defending:

"Methods This study took a qualitative approach, using semi-structured interviews with n=15 industry leaders" .. "Participants were identified via media reports " .. "A total of n=15 key informants participated in this study" .. "Recent research into appropriate sample sizes for qualitative research found saturation typically occurs between 9 and 17 interviews and the researchers agreed that no fresh insights or themes arose after the twelfth interview in this study (Hennink & Kaiser, 2022)"

The interviews contain invaluable insights such as: “adopting the 4DWW takes work” “Productivity up, waste removed” “Management -led/employee -driven,” “Train for leisure,”

I stand by my statement.
