SSCP · Question #1321
While there are many different models for IT system life cycle, most contain five unique phases. Which of the following would be the last phase?
The correct answer is C. Disposal. The disposal phase marks the end of an IT system's life cycle, where the system is formally retired and its data and hardware are securely handled.

Why each option
The disposal phase marks the end of an IT system's life cycle, where the system is formally retired and its data and hardware are securely handled.
Development occurs in the middle of the life cycle, after design and before implementation.
Initiation is the very first phase of the system life cycle.
The disposal phase is the final stage in most system life cycle models, involving decommissioning the system, archiving data, and securely disposing of assets.
Operation/Maintenance occurs after implementation and before disposal, during the system's active use.
Implementation is a middle phase, where the developed system is deployed.
