HR Employee Analytics

A complete HR analytics project built in Excel, covering data cleaning, KPI calculations, exploratory data analysis, pivot tables, dashboards, and business insights.

Author: Younes Boumouh Role: Data Analyst

πŸ“Œ Project Summary

This project analyzes HR data for ~690 employees across multiple countries and centers. The goal is to assess:

Compensation fairness

Workforce distribution

Tenure & performance trends

Workload & absence patterns

The analysis delivers practical recommendations to improve compensation equity, reduce burnout, and optimize staffing.

πŸ“ Business Problem & Goals Problem

The company needs to confirm that:

Its compensation structure is fair

Workload is balanced

Absence patterns do not affect productivity

Staffing is aligned with operational needs

Without this analysis, the organization risks:

Losing high-performing employees

Overpaying in some roles or locations

Suffering productivity drops

Burnout due to excessive overtime

Project Goals

Compensation Analysis by gender, department, country, and center

Workforce Demographics (gender, locations, department distribution)

Performance & Workload (Job Rate, Overtime Hours)

Absence Trends: Sick Leaves & Unpaid Leaves

Actionable Recommendations for staffing, compensation, and operations
