What is the difference between Agile, DevOps, and ITSM?

Agile is an adaptive approach to software development that focuses on an iterative process, rapid feedback, and adaptation to change.

DevOps extends the principles of Agile across the entire software value chain, integrating development and operations to accelerate delivery and increase reliability.

ITSM (IT Service Management) is a set of processes and practices for designing, implementing, operating, and improving IT services, aimed at meeting business needs.

Key differences:

Aspect	Agile	DevOps	ITSM
Goal	Rapid and flexible software creation	Fast and reliable software delivery	Providing quality IT services
Focus	Development	Collaboration between Dev and Ops	Managing all IT services
Scope	Development process	Entire software lifecycle	Managing IT infrastructure and services
Methodology	Agile, iterative	Automation, collaborative culture	Process-oriented (e.g., ITIL)

Agile can be part of the DevOps approach, and DevOps can be applied to improve ITSM processes, as automation and faster delivery impact the efficiency of IT service management. ITSM provides a framework for processes that can be optimized using DevOps practices.
