This chapter begins with a general introduction to employee churn/turnover and reasons for turnover as shared by employees. You will learn how to calculate turnover rate and explore turnover rate across different dimensions. You will also identify talent segments for your analysis and bring together relevant data from multiple HR data sources to derive more useful insights.

Introduction

In this chapter, you will create new variables from existing data to explain employee turnover. You will analyze compensation data and create compa-ratio to measure pay equity of all employees. To identify the most important variables influencing turnover, you will use the concept of Information Value (IV).

Employee data

Pertumbuhan organisasi sangat bergantung pada retensi karyawan. Sering kehilangan karyawan berdampak pada moral organisasi, dan merekrut karyawan baru lebih mahal daripada mempertahankan yang sudah ada. Kabar baiknya, organisasi dapat meningkatkan retensi karyawan dengan strategi intervensi berbasis data. Kursus ini berfokus pada akuisisi data dari berbagai sumber SDM, mengeksplorasi dan menurunkan fitur baru, membangun dan memvalidasi model regresi logistik, dan akhirnya menunjukkan cara menghitung ROI untuk strategi retensi yang potensial.
