Workflow optimization is the systematic process of improving business operations by identifying inefficiencies, eliminating waste, and maximizing resource utilization to achieve faster delivery and higher quality outcomes. Rooted in Lean manufacturing and Six Sigma methodologies, it has evolved into a critical discipline for modern organizations facing complex, interconnected processes. The key mental model to internalize: workflows are living systems where every step either adds value or creates friction—your job is to identify constraints, reduce variation, and continuously iterate toward smoother flow.
