Personas and jobs to be done (JTBD) provide complementary insights for product design, enabling prioritization among different user needs. Personas focus on unique user groups (like busy parents or budget-conscious seniors), while jobs to be done focus on their different tasks or goals (like finding products quickly or comparing prices). Together, they help teams determine what users aim to achieve and prioritize features accordingly.

Using both multiple personas and jobs to be done makes sense as they offer varied perspectives on users. A multifaceted approach captures the breadth of users' needs and goals, allowing teams to address a wider audience. For example, if a particularly significant job to be done, like "quick product search," is associated with multiple personas, it can be prioritized over other, less important functionalities.

While both tools are valuable, there's a key difference between using multiple personas and jobs to be done. Personas provide insights based on demographic or behavioral characteristics, helping teams understand unique user needs and empathize with varied user groups. On the other hand, jobs to be done reveal common user goals across different groups, regardless of their personas, focusing on task completion. When used together, they provide a comprehensive understanding of user needs, supporting strategic product development.^[1]
