Functional Dependency Network Analysis

6.1      Introduction

Critical considerations in engineering systems, systems of systems, and enterprise systems are identifying, representing, and measuring the effects of dependencies between suppliers of technologies and providers of services the consumers. The importance of this topic is many-fold. Primary, is to study the ripple effects of failure in one capability on other dependent capabilities across an enterprise as a highly connected system. Providing mechanisms to anticipate these effects early in design enables engineers to minimize dependency risks that, if realized, can have cascading unwanted effects on the ability of a system to deliver its services.

One way to approach dependency ...
