The first phase of PDP is of the UX designer’s responsibility and its objective is to gather evidence that will support the decisions taken henceforth, ensuring that no decision is made based on vague assumptions. This is the phase in which the main aspects of the business model and user needs are identified.

3. Design Benchmark


Ideation is the core of the creative process and it's where the concept of the product will be formulated based on the user’s needs and the business model, both identified in the Research phase. Here, the UX designer, the visual designer, and the product owner should work closely together.
