  - Mandatory dependencies (hard logic) are inherent in the nature of the work and cannot be avoided — for example, you must pour the foundation before building walls. Discretionary dependencies (soft logic) are based on best practices, experience, or preferences but could technically be changed — for example, preferring to complete testing before documentation. Understanding this distinction is crucial because discretionary dependencies can be modified during schedule compression.
