Navigating Waterway Systems: Comparing Workflow Logic and Process Design
When a waterway authority decides to modernize its navigation control system, the team quickly encounters a fork in the road: should they design around workflow logic or process design? The choice affects how locks sequence, how traffic advisories propagate, and how maintenance crews respond to anomalies. This guide compares the two paradigms at a conceptual level, offering decision criteria, trade-offs, and implementation paths for teams operating inland waterways, canal networks, or port approaches. Who Must Decide and Why the Timeline Matters The decision between workflow logic and process design typically lands on the desks of systems engineers, waterway operations managers, and IT architects during the early planning phase of a control system upgrade or new build. The pressure to choose often comes from two directions: the need to integrate with legacy supervisory control and data acquisition (SCADA) systems, and the desire to adopt more flexible, event-driven architectures that can handle variable traffic patterns and weather conditions. A common mistake is treating the choice as purely technical. In reality, the decision shapes how operators interact with the system, how easily new rules can be added, and how the system degrades under failure. For example, a workflow-based system might excel at guiding
