Do you have more experience in run activities or in change? Specifically in software development and production?

In software development and operations (DevOps, IT Operations), two main areas are distinguished:

• Run activities (operations) — support, monitoring, incident resolution, ensuring system stability.
• Change activities (changes) — developing new features, fixing bugs, implementing updates.

Experience in run activities implies skills in quick problem response, working with monitoring systems, automating routine tasks, incident management.

Experience in change activities involves coding, architecture design, testing, working with version control systems and CI/CD.

Often, specialists have mixed experience, but it is important to understand where their competencies are more:

• If you mainly supported and maintained systems, your experience is in run.
• If you developed and implemented software, your experience is in change.

When answering interview questions, it is useful to provide specific examples of tasks and projects where you participated in development or operation.
