research – synthesis interviews with stakeholders

I am new to UX and working on my first project.

I have conducted interviews with business stakeholders to understand the goals of the company and the project.

Stakeholders involved:

  1. Marketing
  2. Sales
  3. Professional services
  4. Product manager
  5. Support

Could someone tell me how to synthesize the interview with stakeholders? And share the model to present ideas on the results of stakeholder interviews?

As I have to present it to the stakeholders about the vision and shared objectives of the project.

Once that is ok, I will start the interview with the users.

Thanks in advance !!
