This document provides a set of critical considerations to be addressed at key points in the life cycle of systems created by humans. This document refers to a constituent system that will interact in a system of systems as the system of interest (SOI). These considerations are aligned with ISO/IEC/IEEE 15288 and the ISO/IEC/IEEE 24748 framework for system life cycle stages and associated terminology. Selected subsets of these considerations may be applied throughout the life of systems. This is accomplished through the involvement of all stakeholders with the ultimate goal of achieving customer satisfaction by ensuring that when delivered, the system will operate effectively in the operational or business environment which will typically be characterized as one or more systems of systems. This document concerns those systems that are man-made and are configured with one or more of the following: hardware, software, humans, procedures and facilities.

This document provides a set of critical system of systems (SoS) considerations to be addressed at key points in the life cycle of the system of interest (SoI). This document refers to considerations that apply to an SoI that is a constituent system that interacts in an SoS. The considerations and life cycle model align with those which are already defined in ISO/IEC/IEEE 15288 and ISO/IEC/IEEE 24748-1. Selected subsets of these considerations can be applied throughout the life of systems through the involvement of stakeholders. The ultimate goal is to achieve customer satisfaction, so that when delivered, the SoI will operate effectively in the operational or business environment which is typically characterized as one or more systems of systems. This document concerns those systems that are man-made and are configured with one or more of the following: hardware, software, humans, procedures and facilities.
