Once the documentary has been financed, the production team must determine the budget and design an appropriate production plan. As with the artistic field, the unpredictability of working with reality is decisive in this organization, so flexibility in management is absolutely necessary in the three phases, pre-production, filming and post-production. The selection of the technical team is another key factor, especially in productions where the human factor can be delicate or where deadlines are extended over time. Documentary film faces specific challenges for production such as ethical issues and the management of rights and legal aspects.
