Data Science Human Resources refers to the management and deployment of personnel within an organization who specialize in the field of data science. These human resources encompass professionals with expertise in data analysis, machine learning, statistics, programming, and other related domains.

HR Data Science, or People Analytics or Workforce Analytics, is the practice of gathering, analyzing, and reporting HR data. It enables organizations to gain a better understanding of their workforce, measure the impact of various HR metrics on overall business performance, and make data-driven decisions. Essentially, HR data science is a data-driven approach to human resources management.

Understanding the Intersection of Data Science and HR

Data science, in essence, is the study of data with the intent to gain valuable insights that can drive decision-making. It combines elements of mathematics, statistics, artificial intelligence (AI), and computer engineering. When applied to the realm of HR, it allows for a more analytical and evidence-based approach to managing human capital.

Types of HR Data Science

HR analytics can be classified into four types based on the purpose and the level of insight they provide:

  1. Descriptive HR Analytics: This type of analytics examines historical data to understand what has happened in the past. For instance, it can help determine the annual turnover rate of an organization.
  2. Diagnostic HR Analytics: It delves deeper into the data to find out why something happened. For example, it can examine absenteeism data to identify the drivers of absenteeism within an organization.
  3. Predictive HR Analytics: This approach uses current and historical data and statistical models to predict future behaviors and events. For instance, it can explore recruitment data to determine the top attributes of the ideal candidate for a specific role.
  4. Prescriptive HR Analytics: The most advanced form of analytics, it suggests potential future outcomes and scenarios and proposes recommendations to address them. For example, it can develop an algorithm to predict the kind of onboarding a new hire might need based on their experience and skill level.

Key HR Metrics for Data Science

HR metrics are important pieces of information for keeping track of human capital and figuring out how much HR projects are worth. In data science, some of the most common HR metrics are the ones below:

  • Employee Turnover: This is the percentage of employees who leave the organization during a specific period. Analyzing employee turnover can reveal helpful insights, such as which departments, positions, or managers lose the most workers.
  • Absenteeism: This refers to the habitual non-presence of an employee at their job without valid reason or notification. A high number of unplanned absences can be a sign that employees are unhappy and point out which areas of the organization need attention before they lead to more turnover.
  • Revenue per employee: This is the average revenue generated per employee, usually calculated on an annual basis. It reflects the organization’s overall efficiency.
  • Employee Net Promoter Score (NPS): This metric reflects employee loyalty and satisfaction with the organization as an employer. The higher the score, the more likely it is that employees are satisfied and willing to promote the organization.
  • Cost per hire: This metric illustrates what it costs to recruit an employee. It factors in all of the associated expenses, such as recruitment advertising, background checks, referral or sign-on bonuses, and administrative and staffing costs.

Data science can help HR professionals make plans for the future that are in line with the organization’s goals by revealing trends in the workforce and predicting what workers will need in the future.

Workplace Safety

Safety at work is very important for making sure that employees are healthy. By looking at data like injury rates and absence rates, data science can help find safety risks. This lets HR professionals come up with safety plans that deal with potential risks and make the workplace safer overall.

The Role of the HR Data Scientist

HR data scientists are professionals who apply data science methodologies to HR functions. They are also known as HR data scientists. A unique combination of data science expertise, human resources expertise, and soft skills is required for this position. They must possess the ability to analyze complicated data, interpret statistical models, and provide stakeholders with recommendations that are both clear and actionable.
