Inventory Database
To support LP&L’s long-term inventory management improvement initiative, I developed a dynamic, Excel-based Inventory Database designed to increase transparency, streamline material inquires, and provide engineers with immediate access to item specifications, historical unit costs, and approved manufacturer data. With nearly 1,000 active inventory items across multiple locations, this project began with the collection and cleanup of usage data from JD Edwards (E1), followed by the reevaluation of reorder points (ROP) and economic order quantities (EOQ), which I visualized in a dedicated dashboard for comparison.
From there, I audited and updated specification details, verified approved manufacturers, and standardized formatting across both the internal ERP system and the database itself. To ensure long-term usability, I build a scalable backend Power Query, allowing the system to be refreshed and maintained by future supply chain interns with minimal disruption.
During the process, I identified over 90 obsolete (“dead”) items – 56 of which still had physical stock in the warehouse. I collaborated with the Purchasing team to initiate an auction and successfully began clearing these materials. Once the database framework was complete, I authored both a Maintenance Guide for future interns and a User Guide for engineers, ensuring the tool could be easily navigated, understood, and sustained in the long term. To supplement these guides, I also produced a short video walkthrough that visually demonstrates how to use and maintain the database – making onboarding faster and more intuitive.
With the system now live, the next phase focuses on catalog number validation. Many specifications haven’t been updated since the 2010s, and the tool is not structured to include only manufacturers and CAT#s verified as valid, current, and relevant.

Key features included:
Interactive Specifications Search: A user-friendly interface which allows engineers to instantly search inventory records by item name, warehouse number, or category. Powered by dynamic array formulas and backend Power Query logic, this tool returns detailed results including technical specs, approved manufacturer/CAT# combos, ROP/EOQ, unit costs, and lead times – all without navigating between sheets or reports.
Demand-Driven ROP & EOQ Adjustments: Recalculated reorder points and economic order quantities using actual usage history, lead times, and cost assumptions. Results are visualized with severity rankings to help prioritize updates and improve purchasing strategy.
Deadstock Identification & Clearance: Flagged 90+ nonmoving inventory items, including 56 with remaining on-hand quantities. Partnered with Purchasing to initiate an auction and begin removal, freeing up warehouse space and reducing carrying costs.
Guides & Walkthroughs for Future Use: Authored both a Maintenance Guide for backend edits and a User Guide for engineers. These resources include troubleshooting tips, step-by-step instructions, and documentation for future updates or intern handoffs. A supplemental video walkthrough was created to make the learning curve even shorter for new users and editors.
An Important Note:
All data shown in sample workbook views is fabricated for demonstration purposed and does not reflect real inventory, pricing, or supplier infromation from Lubbock Power & Light. Some values have been intentionally altered or redacted to protect sensitive operational data and vendor relationships. This project was developed for internal improvement and use only, and no propriety information is publicly shared.
Project Deliverables
-
A fully functional, Excel-based database system housing nearly 1,000 cleaned and categorized inventory items. Includes 11 sheets in total, 5 of those being user facing.
-
A clear, concise walkthrough designed for engineers and other end users. Explains how to search for item specification, interpret results, and apply category filters – ensuring accessibility and suability across the department.
-
A comprehensive reference for future editors and interns. Covers everything from data entry and Power Query refreshed to restoring search functionality, validating catalog numbers, and cleaning obsolete records.
-
A short, guided video overview showing how to navigate the tool, perform updates, and troubleshoot common issues. Created to supplement the written guides and accelerate onboarding.
Final Reflections
This project sharpened my ability to design scalable data systems that balance technical structure with everyday usability. I gained hands-on experience transforming raw ERP outputs into a clean, searchable interface while coordinating with cross-functional teams to ensure the tool served both operational and strategic goals. More importantly, it laid the foundation for future inventory decisions at LP&L and equipped the department with a transparent, sustainable resource for years to come.
