"ABC analysis is Linear (1D), while EIQ analysis is Mesh (2D)."
ABC analysis defines characteristics as directional vectors, whereas EIQ analysis creates a 2D matrix of E (Orders) and I (Items). This provides vital "from-to" information in addition to basic characteristics.
ABC Analysis (1D)
Aggregates Orders (E) and Items (I) separately. While totals match, there is no direct correlation between their respective ranks.
Expert Tip: Ideal for a strategic macro view—identifying top-tier customers or high-volume items independently.
EIQ Analysis (2D)
Cross-tabulates E and I. It identifies which item ranks are flowing to which customer ranks, ensuring ranks are perfectly synchronized.
Expert Tip: Essential for tactical design—optimizing picking areas or selecting specific logistics equipment based on flow.
Conclusion: Use ABC analysis for overall strategy and EIQ analysis for detailed technical improvements and warehouse design.
