How can systems engineering help in IT service management?

Systems engineering brings a structured, end-to-end approach to ITSM.. It helps align people, processes, and technology, ensuring services are reliable, scalable, and meet business goals. Think of it as designing IT services with the same rigor you'd use to build a spacecraft...  nothing left to chance.  For example, if service desk keeps getting overwhelmed with recurring incidents, like slow response times, inconsistent resolutions, and poor user satisfaction, etc..a systems engineer steps in and maps the entire service lifecycle, basically from ticket intake to resolution, etc. They identify bottlenecks, automate repetitive tasks (like password resets), and redesign workflows. This then ultimately results in faster resolution times, fewer errors, and a smoother experience for both users and support teams.

My thoughts:

At the management level:
Think about the IT organization as a metasystem who should provide business enhancement.
What do you need from this metasystem? (system request elicitation, service design, SLAs etc)
How do you design the organization (hierarchical, matrix, functional etc)? (system design)
How do you integrate the IT organization into your business architecture? (system integration, enterprise architecture)
How do you know the IT organization is doing the right thing (i.e. KPI)? (Testing and validation)
What improvements are needed? (continuous improvement, PDCA etc)

At the technical level:
All the systems should be designed and work to provide the most appropriate services for the business. The appropriate service is the one which is negotiated with the business in terms of business value and guarantee and TCO.
