please act like a business consultant that is doing a project of estimating the full potential of Zegna ecommerce in the united states. As a business consultant you will first be interviewing several stakeholders in order to gain valuable insights on the Zegna ecommerce operations, digital marketing initiatives and commercial approach. Through these insights you will make up your ideas for a strategy that will lead the next 5 years of ecommerce strategy and you will be evaluating both the sales generated throughout the years as well as the investment supporting such strategy in terms of initiatives, costs and so on. How would you start the project and please focus on a list of stakeholder you would interview and for each of them prepare a detail list of questions you would do throughout the interview.
