Guidance notes

This skill involves interdisciplinary approaches to developing and operating software and systems across their entire lifecycle. Commonly associated with terms such as DevOps, DevSecOps, site reliability engineering, developer productivity engineering.

This skill extends beyond continuous improvement. It focuses on integrating technical practices and collaborative methods, automation and lifecycle processes essential for system reliability, security and operational excellence.

Activities include, but are not limited to:

  • establishing secure, reliable software lifecycle practices
  • developing a supporting framework of methods, tools, processes, procedures and skilled personnel
  • deploying this environment with teams responsible for developing and operating software and systems 
  • building repeatable, reliable capabilities through trial, feedback, learning and continual evolution
  • adapting practices to specific products and services
  • defining, controlling and improving lifecycle processes
  • incorporating risk management, quality, security, privacy and safety
  • maximising automation
  • establishing architecture and design principles to support lifecycle processes
  • focusing on mission, value and customer needs
  • cultivating a culture of collaboration, learning, adaptation and resilience
  • integrating industry frameworks to guide improvements.

Understanding the responsibility levels of this skill

Where lower levels are not defined...
  • Specific tasks and responsibilities are not defined because the skill requires a higher level of autonomy, influence, and complexity in decision-making than is typically expected at these levels. You can use the essence statements to understand the generic responsibilities associated with these levels.
Where higher levels are not defined...
  • Responsibilities and accountabilities are not defined because these higher levels involve strategic leadership and broader organisational influence that goes beyond the scope of this specific skill. See the essence statements.

Developing skills and demonstrating responsibilities related to this skill

The defined levels show the incremental progression in skills and responsibilities.

Where lower levels are not defined...

You can develop your knowledge and support others who do have responsibility in this area by:

  • Learning key concepts and principles related to this skill and its impact on your role
  • Performing related skills (see the related SFIA skills)
  • Supporting others who are performing higher level tasks and activities
Where higher levels are not defined...
  • You can progress by developing related skills which are better suited to higher levels of organisational leadership.
