Which statement is true regarding roles in Disciplined Agile?

In Disciplined Agile, the flexibility to have one person hold multiple roles within a team is a fundamental concept. This approach emphasizes that team members can bring a diverse set of skills and experiences to the table, allowing for a more adaptable and responsive team structure. By allowing individuals to take on multiple roles, teams can ensure that all necessary functions are covered without being constrained by rigid job titles or responsibilities. This can lead to increased collaboration and a better understanding of the team's dynamics and challenges, as team members can engage in various capacities as needed.

The other statements do not align with the principles of Disciplined Agile. The emphasis on specialization can inhibit a team's ability to flexibly respond to changes and demands, while a strong leadership presence in technical decisions is meant to be a collaborative effort rather than the sole responsibility of one individual. Additionally, the allocation of resources typically involves considerations beyond a single Team Lead, promoting shared responsibilities within the team context.
