Executive Summary:

This dashboard was built to eliminate the hassle of manual maintenance tracking for production carts. By combining dynamic scheduling formulas, live overdue status flags, and KPI tiles, it gives operations leaders a clear, instant view of what needs attention. Users can quickly identify overdue carts, prioritize high-risk units, and make data-driven maintenance decisions, all within a streamlined Excel interface.

Initial dates were miscalculated for year “2099”, all were replaced with randomized, realistic past dates to simulate actual cleaning cycles for demonstrative purposes and anonymity.

Helper column (L) added to calculate Days Overdue-this powers downstream KPIs and highlights overdue pods automatically.

The KPI “Average Days Since Last Clean” is calculated in cell B4, giving managers an at-a-glance metric for overall maintenance health.

Project Overview

This project tackled a recurring compliance challenge in cart maintenance management at a semiconductor facility. Manual tracking caused missed maintenance, compliance risks, and operational inefficiencies. The solution: a fully automated, real-time Excel dashboard for tracking, triage, and compliance.

My Approach

• Imported and centralized raw cart records as the project’s single source of truth.

• Cleaned and standardized maintenance log data in Excel for consistent reporting.

• Built helper columns and dynamic formulas to automate service intervals, overdue flags, and KPI calculations.

• Automated KPI tiles (overdue carts, high-risk carts, average days overdue, carts due this week).

• Applied color-coded conditional formatting to instantly flag maintenance risk.

• Created a live dashboard interface for ops teams to monitor status and drive decisions.

Business Impact

• Reduced missed cart maintenance and compliance risk.

• Enabled instant triage of high-risk carts.

• Minimized manual data entry and improved real-time reporting.

• Provided a scalable, reusable template for other facility teams.
