A critical aspect of the system life cycle is that the system development phase of the life cycle is the phase of the life cycle where all future life cycle phases are planned and designed. For instance, as an automobile is designed for a particular model year, it is designed and codified as a “build-to” specification. This buildto specification will define the form, fit and function of every component and subsystem of the automobile.
Likewise, the designers will, if necessary, design new tools for fabricating components and will design the building and assembly process. Additionally, designers will need to identify the types and numbers of spare parts that will be needed and will calculate the automobile’s reliability and maintainability parameters so that warrantees can be developed. All of these development issues will be initially designed and determined during the development stage.
Information system development requires the same rigorous approach as other complex systems.
The development of information systems follows some form of conceptualization phase. The development process requires a complete understanding of how the system will be built, configured, deployed, operated,
supported and eventually replaced.

Systems are the mechanisms by which organizational operations occur. Typically, information technologies are transformed into information systems such that those systems are aligned with operational activities of the organization. From a Continuity of Operations (COOP) perspective, it is important to develop systems
that support anticipated COOP environments or can be realigned with new, and often unexpected, COOP operational requirements. To do this effectively, organizations must develop operational COOP requirements and inject them into the systems development process. The process, if effective, will generate systems that
can support a variety of COOP situations.
