A mid sized software company is creating a group to handle production incidents and they want the team to be most effective. What team composition usually produces the best outcomes?

Relying mainly on the Site Reliability Engineering (SRE) team without other disciplines might lead to gaps in specific application knowledge or business context.

Staffing only with top software engineers might lack operational expertise, security knowledge, or business context necessary for effective incident management, which often involves more than just code-level fixes.

Composing the team exclusively of senior management would be inefficient and ineffective for hands-on incident resolution, as they typically lack the technical depth required.

A cross-functional team with representatives from all required disciplines, such as development, operations, security, and business stakeholders, ensures comprehensive incident resolution by bringing diverse perspectives and skills for faster diagnosis and effective mitigation.
