The idea that analyzing travel apps has not directly influenced the survey is absurd without concrete proof of a formal decision to ignore it.
A clear process is necessary to establish traceability and ownership between these steps.
A simple market analysis report without sign-off and without a governance meeting to formalize decisions is not a sufficient input to say that influence does not exist.
For example, for launching a new service, one cannot claim that the feasibility study did not influence the business plan if a decision to ignore its conclusions has not been documented.
