This chart illustrates that design quality is not the same for all situations.
Because quality depends on the investment, the quality of the operational procedures is different for the different operational scenarios. The design quality depends on the costs of the specifications, design and testing, evaluated for each of the operational states, as follows:
Due to limitations of development costs, the rules defining proper behavior in exceptional situations are often designed and tested with less care than required. The design scope defines the focus of resilient-oriented design.
