HR Learning of the Day Inverse Gaussian Model for Labour Turnover

The Inverse Gaussian Model for labor turnover is a statistical approach used to predict and analyze employee turnover rates over time. This model is particularly useful when turnover events are spread irregularly across a time period. It helps organizations understand patterns of employee departure and estimate the likelihood of turnover under varying conditions.

Key Features:

1. Continuous Probability Distribution: The Inverse Gaussian model describes time until an event (e.g., resignation) occurs and is especially useful for modeling positively skewed data.

2. Parameters:

Mean (µ): Average time to turnover.

Shape Parameter (λ): Controls the variability in the timing of turnover.

3. Application: It accounts for factors such as:

Job dissatisfaction.

Economic conditions.

Managerial interventions.

Organizational policies.

Relevance to HRM:

1. Predictive Analytics: Helps HR professionals anticipate when turnover spikes might occur, allowing for timely interventions.

2. Risk Management: Identifies roles or departments with high turnover likelihood, enabling focused retention strategies.

3. Optimized Recruitment: Supports workforce planning by forecasting vacancies and recruitment needs.

Example:

Suppose a company observes that turnover peaks at the 6-month and 2-year marks of employment. Using the Inverse Gaussian model, HR can:

Quantify the probability of employees leaving during these periods.

Tailor engagement and retention programs to minimize turnover.

Implications:

Retention Strategies: Enhanced focus on improving employee satisfaction during critical periods.

Cost Reduction: Lower recruitment and training expenses by reducing turnover rates.

Data-Driven Decisions: Provides a scientific basis for HR policies.
