3. Assess project uncertainties

This assessment, which is often associated with the review of input elements, deserves to be clearly identified, on the basis of the risk-based approach introduced by ISO 9001, in order to increase the relevance of project planning, and particularly its milestones.

As a matter of principle, a design and development project involves uncertainties, which are factors of risk (negative effect) and opportunity (positive effect).

For example, a function and/or level of performance different from those usually achieved leads to uncertainties, since we don't know a priori how to achieve them. These uncertainties can have a number of effects:

• potential negative effects (risk), such as not achieving the objective, taking too long to achieve it, incurring too high a development or production cost......
