Demanding markets and complex products are only some of the reasons that make changes and variations inevitable through different stages of product realization. From early phases of product development to downstream production phase, these changes or variations cause failure either directly or by propagating to other phases, triggering more fluctuations like the well-known butterfly effect. In this paper, first, the definition of changes in product realization will be reviewed and then different papers and their classification on change related system properties (illites) will be discussed and compared. It was argued that considering a system-level view, one could trace these propagations in the systems as a result of not being robust, flexible, or adaptable, etc. Some of the ambiguity in this semantic field demonstrated and most repeated definitions are identified as the unanimous and agreed-upon definitions in the literature. In the end, a historical comparison of the three identified properties presented. The results of this study help us to understand the multidisciplinary nature of these propagations and identify their stemming turbulent environment. This will be used as a foundation for forthcoming research either to prevent these propagations or utilize their attributes in the product realization.
