This document explores the application of Correspondence Analysis (AFC) on a dataset named 'foods' to examine relationships between variables. Pearson's Chi-squared test was conducted (X-squared = 647.31, df = 91, p-value < 2.2e-16), though a warning on the accuracy of the approximation was noted. Key analytical metrics such as weights, squared distances, inertia, and modal coordinates were computed. Additionally, graphical representation of modal positioning was generated to better decode the data structure.
The document introduces Lean Management principles using the DMAIC framework and emphasizes the importance of Value Stream Mapping (VSM) to optimize workflows. Metrics such as production capacity (pieces per hour), lead times, and client demand are analyzed across various posts in workstations. Calculations like Process Lead Time (PLT) and Process Cycle Efficiency (PCE) are central to achieving operational efficiency. Practical examples and exercises guide readers through the application of Lean methodologies with calculated data points.
