The P3O Foundation (2013) manual indicates that the Blueprint's information flows deliver the principle of management by exception. Section 4.3.3 states, "The Blueprint's information flows support the principle of management by exception by providing senior management with critical data to focus on deviations rather than routine operations." This differs from the implementation plan (A), risk management (B), or benefits realization (D), which are separate processes. The 2013 edition highlights this principle as a governance mechanism, enabling efficient oversight by escalating only significant issues. This enhances P3O's strategic focus during implementation.
