Process improvement is a systematic, data-driven approach to increasing the efficiency, effectiveness, quality, and adaptability of organizational processes. It aims to reduce waste, variability, and cycle times while improving value for customers. The work typically includes identifying opportunities, mapping current processes, designing and piloting changes, implementing them, and measuring results to guide further action.

Key methodologies include Lean, Six Sigma, Kaizen, and the PDCA cycle. Lean targets waste elimination; Six Sigma reduces variation and defects; Kaizen emphasizes continuous incremental gains; PDCA provides a repeatable cycle for small tests. DMAIC is a common Six Sigma framework: Define, Measure, Analyze, Improve, Control.

Applications span manufacturing, software development, healthcare, finance, and services. Techniques such as value stream mapping and process mapping help visualize flows, while digital tools enable data collection, experimentation, and deployment of changes.

Common metrics include cycle time, lead time, throughput, defect rate, and process capability (Cp/Cpk). Tools used are root-cause analysis, cause-and-effect diagrams, the 5 Whys, and control charts. Success depends on clear ownership and stakeholder engagement.

Successful implementation requires defined roles (process owner and improvement teams), governance, training, and change management. Sustained gains come from standardization, documentation, and periodic review to prevent regression and embed a culture of continuous improvement.
