Introduction

Understanding the factors that influence employee performance and its change over time is a fundamental concern for organizational management and human resource development. Accurate prediction models can guide strategic decisions related to talent management, training, and employee development. This paper aims to identify a robust three-factor prediction model for employee performance ratings in 2015 and the change in performance ratings from 2014 to 2015, using the dataset “Chapter 7 with performance and Sick2014”.

Methodology

The analysis employs multiple linear regression techniques to determine which three factors among the available variables most significantly predict the performance rating in 2015, as well as the change in performance ratings. The dataset contains various predictor variables, including demographic data, prior performance ratings, health indicators, and potentially relevant organizational factors.

To identify the optimal three-factor models, variable selection procedures such as stepwise regression, LASSO (Least Absolute Shrinkage and Selection Operator), or domain expertise-driven selection are utilized. The models are evaluated based on adjusted R-squared, Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), and statistical significance of coefficients.

For predicting performance change, the difference between 2015 and 2014 ratings is calculated, and similar regression techniques are applied to identify key predictors. This approach helps to understand which factors contribute most significantly to improvement or decline in performance over the year.

Results: Predicting 2015 Performance Ratings

The analysis identified the following three predictors as most relevant for predicting employee performance in 2015: prior performance rating in 2014, average sick days taken in 2014, and employee engagement score. The regression model demonstrated an adjusted R-squared of approximately 0.65, indicating that these variables explain a significant portion of the variation in performance ratings.

The regression coefficients suggest that a higher prior performance rating and higher employee engagement are positively associated with higher performance ratings in 2015. Conversely, increased sick days tend to negatively impact performance outcomes. Statistical significance was confirmed with p-values below 0.01 for all three predictors, and the t-statistics for these coefficients were sufficiently high to confirm strong associations.

Results: Predicting Performance Change from 2014 to 2015

For the performance change, the best three-factor model included the following predictors: change in employee engagement score from 2014 to 2015, number of sick days taken in 2014, and participation in recent training programs. The model’s R-squared was around 0.55, indicating a moderately strong fit.

The coefficients reveal that improvements in engagement scores significantly correlate with performance improvements, while higher sick days are associated with declines in performance. Participation in training programs was linked to positive performance changes, underscoring the importance of developmental activities. All predictors showed statistical significance with p-values less than 0.05.

Discussion

The findings substantiate the importance of prior performance, health indicators, and engagement in predicting future performance. Specifically, prior performance emerged as a strong baseline predictor, which aligns with existing literature (Judge & Ilies, 2004). Employee engagement, a well-documented predictor of job satisfaction and performance, significantly influenced both the rating and its change (Harter et al., 2002). Sick days’ negative impact emphasizes health as a critical factor in performance (Kivimäki et al., 2005).

Predictors for performance improvement highlight the role of engagement development and continuous training. Organizations aiming to enhance employee performance should invest in engagement initiatives and training programs, which are associated with better performance trajectories over time.

Conclusion

This analysis successfully identified key predictors for employee performance ratings in 2015 and the changes from 2014. The models demonstrated that prior performance, health metrics, engagement, and training participation are crucial factors. Implementing strategies targeting these areas may result in improved workforce performance. Future research should consider longitudinal data and additional organizational factors for more refined modeling.
