👉 Omissions engineering refers to the deliberate design choices made by engineers to exclude certain aspects, components, or functionalities from a system's design, often to simplify complexity, reduce costs, or enhance performance in specific areas. This practice involves identifying which elements are not critical to the system's primary objectives and intentionally omitting them, thereby streamlining the design process and potentially improving efficiency. However, it can also lead to unintended consequences, such as reduced flexibility or increased risk if the omitted elements are crucial for certain scenarios. Effective omissions engineering requires a deep understanding of the system's core functions and careful consideration to ensure that the absence of these elements does not compromise overall performance or reliability.
