When we sat down with Lauren Wegman, Head of People Analytics at Twitter, for this episode of Reimagining Company Culture, the conversation kept returning to a tension every HR analytics leader recognizes. The discipline is supposed to produce rigorous evidence about people, work, and the future of both. Most companies still treat it as a reporting function. Lauren has spent her applied career documenting changes in work and workers, and her argument was that people analytics is most valuable when it stops producing dashboards and starts producing decisions.
Her framing was practical for HR leaders who feel the pressure to add analytics capacity without quite knowing what to do with it. The discipline has to be designed around the questions the business actually needs to answer, the data infrastructure that produces reliable signal, and the partnerships across departments that turn analysis into action.
Why People Analytics Is the Quiet Lever Behind Strategic HR
Most HR functions are still operating on a fraction of the data they could be using. McKinsey research has documented that companies with mature people analytics functions outperform peers on retention, productivity, and equity outcomes. The gap between mature and immature analytics functions is one of the largest hidden gaps in modern HR.
Lauren described people analytics as a discipline that combines rigorous methodology with genuine business partnership. The methodology produces credible evidence. The partnership ensures the evidence ends up in the decisions where it matters. documented years ago that the analytics teams that produce decisions, rather than reports, are the ones that earn ongoing investment from senior leadership.
What Defining People Analytics Actually Requires
What is people analytics?
People analytics is the use of rigorous evidence about workforce dynamics to support decisions across hiring, development, retention, performance, and the broader operating model. It includes descriptive analytics that explain what is happening, predictive analytics that anticipate what will happen, and prescriptive analytics that recommend specific actions. The discipline treats the workforce as a system that can be studied with the same rigor a finance team uses for financial systems.
How is it different from HR reporting?
Reporting describes the past. Analytics produces evidence that supports decisions about the future. The strongest people analytics functions move beyond standardized HR reports into custom analyses tied to specific business questions. The shift requires different talent, different tooling, and different relationships with the rest of the business.
What Actually Works When You Build a Useful Analytics Function
Principle 1: Start with the question, not the dashboard
The most common failure mode in people analytics is building dashboards before defining the decisions the dashboards are supposed to support. Strong programs start by interviewing leaders about the questions they need to answer and design the data infrastructure backward from those questions. The dashboard is the output, not the goal.
Principle 2: Build the data infrastructure that supports rigorous analysis
Rigorous analysis requires clean data. HRIS data, performance data, engagement data, and ER pattern data all need to be reliably integrated to produce the kind of evidence senior leaders can act on. Data and insights tooling that consolidates these sources saves the analytics team months of manual integration work.
Principle 3: Partner across departments to turn evidence into action
The strongest people analytics functions partner with finance, business operations, and the leadership teams of every major function. Those partnerships ensure the evidence shows up in the decisions where it matters. Without them, the analytics team produces reports that no one reads and analyses no one acts on.
Where Employee Relations Fits Into People Analytics
People analytics is most useful when it includes the qualitative texture of employee relations data alongside the quantitative HRIS data. ER pattern data tells the story behind the numbers. The dashboard might show attrition is up in one team. ER provides the context that explains why and points to the specific intervention.
How ER strengthens analytics signal
The right ER function gives the analytics team case-level data on the friction patterns that show up across the organization. Investigations management tooling that captures cases consistently is what makes ER pattern data reliable enough for analytics. Without consistent capture, the qualitative signal is too noisy to be useful.
Designing the Future of Work With Evidence
Using data to test new operating models
Distributed work, flexibility, and new manager structures all benefit from rigorous study. Strong analytics functions design experiments, track outcomes, and feed evidence back into operating model decisions. Without that discipline, companies make big changes based on anecdote and discover the cost months later.
The role of people analytics in operating decisions
People analytics belongs in the same conversations where financial and operational data already live. Quarterly business reviews. Talent reviews. Compensation calibration. When the data is in those forums, the decisions improve. When it lives in a separate analytics review, it tends to lose ground over time.
Frequently Asked Questions About People Analytics
What is the difference between HR reporting and people analytics?
HR reporting describes the past. People analytics produces evidence that supports specific decisions about the future. The strongest analytics functions go well beyond standardized reports into custom analysis tied to business questions.
How do you measure analytics function effectiveness?
Useful measures include the number of decisions the analytics function influenced, the time saved on manual reporting, the accuracy of predictive analyses against later outcomes, and the strength of partnerships across the rest of the business.
How does employee feedback data feed analytics?
Employee feedback data is one of the richest sources of qualitative signal. Survey responses, open-ended comments, and ER case patterns all feed into analyses that explain the why behind the numbers. The strongest programs treat qualitative data as core analytics input rather than a separate workstream.
What skills does a people analytics team need?
Useful skills include statistics, data engineering, business partnership, qualitative research methods, and storytelling for non-technical audiences. The team that can do all of these together produces evidence that lands. Teams that have only the technical skills tend to produce reports that no one acts on.
How does analytics support employee retention?
Analytics supports retention by identifying the patterns that predict attrition, the manager behaviors that drive it, and the team-level conditions that reduce it. The most useful analyses connect retention to specific interventions the People team can run.
How Companies Build Analytics Maturity Over Time
From reporting to predictive insight
The maturity curve typically moves from descriptive reporting to predictive analytics to prescriptive recommendations. Each stage requires more sophisticated data infrastructure and stronger business partnerships. Companies that try to skip stages usually struggle because the foundations are not in place.
Investing in the analytics talent the function needs
People analytics talent is competitive across industries. Companies that build mature analytics functions invest in development, give analysts access to senior decisions, and treat the function as strategic rather than as a reporting cost center.
The Bottom Line for HR Leaders
Lauren Wegman's framing of people analytics is the right discipline for HR leaders trying to demonstrate strategic value to senior executives. The function is most valuable when it produces decisions rather than dashboards. The shift requires investment in methodology, infrastructure, and business partnership.
HR leaders who want analytics to actually move outcomes should invest in three things. Start every analysis with a clear business question. Build the data infrastructure that supports rigorous, integrated analysis. Wire analytics into the same operating cadence where financial and business decisions already live. With those in place, people analytics becomes a strategic asset rather than a reporting cost.
