At the recent Ultimate Software user conference in Las Vegas, customers were briefed on new predictive analytic capabilities being incorporated into the Ultimate HR software product.
The following text represents the best notes I could take as the subject was covered rather quickly at the event.
Ultimate Software developers worked with a client that had approximately 3445 employees. They analyzed several years worth of attrition data to determine if there were any common indicators that could be used as predictors of future retention. Five factors emerged (out of 150 total factors examined) that correlated with 85% of the actual attrition customer had experienced.
At this step, Ultimate Software had identified factors that may have been an influence in prior attrition matters. They then ran the same factors against the current workforce to identify:
- what employees exhibit the same factors today
- which employees may warrant intervention
- whether these five factors are still relevant
The predictive analytics module then scored all employees against these five criteria. Ultimate software ranked each of the 3445 or so employees. They then broke the employees into deciles from lowest scores to highest scores. In the lowest-ranked decile, one employee was singled out as having only a 5% chance of staying with the company through the next year. The highest score of any employee in the bottom decile was only 26%. Clearly this 10% of the workforce was at great risk of leaving their employer.
The analysis also showed that the second decile wasn't much better. The employer clearly had a lot of work to do with this portion of its workforce population.
Interestingly, the individual employees within these 2 deciles contained a number of high-performing individuals and high potential individuals. This additional insight was gained once the predictive analytic results were triangulated against the performance management data within the HR system. According to Ultimate Software executives, their customer's management team was stunned to find a number of high-performance and high potential employees at risk for leaving the firm.
Eventually, 78% of the workers indicated as potential flight risks did in fact leave their employer. While this clearly shows that the predictive analytic tool was focused on many of the right factors, it does, to me, indicate that the management of this company either acted too late or did not understand how to effectively intervene with individuals to minimize these attrition losses.
In a breakout session, attendees asked one of the Ultimate Software presenters about the individual predictors used in this one customer's environment. This conversation was enlightening as the speaker told how they used some 150 potential predictors, many of which the speaker thought maybe illogical or unique. However, they have since run these analyses on other workforce groups and have learned that:
- Predictors for one group of workers may not apply to others
- Likewise, predictors for one employer may not apply to another firm
- Some lower paid employers may see a high correlation between retention and the price of gasoline. That is, the higher gas prices move up the less affordable some jobs actually are.
- Anecdotal "evidence" offered up by company executives can often be wrong.
- Management is often surprised by the real factors driving attrition
- Data from exit interviews can only be one input to the analysis as workers may provide incomplete rationale for leaving
To do predictive analytics correctly, I believe that businesses will need the following:
- ample and immediate access to a quality data store of historical data
- individuals skilled in forecasting and analytic model development
- a discipline to test analytic results against current world data to assess the viability of a model built with historical results but using current data
- a competency built around speedy intervention once analytic results have been identified. Businesses that develop great analytic tools but fail to move quickly on the results are simply wasting money.
I have recently covered other HR analytic tools (e.g., Visier and Evolv-OnDemand) and will continue to highlight additional analytic applications as they bring new value to staid back office processes. The future, excitement and business value to emanate from many finance, HR and other applications will have to come from products, like predictive analytic tools, as these can have material bottom line impact. In the example that Ultimate Software demonstrated, reducing attrition materially reduces recruiting, training and other costs. The value is clearly there for firms willing to find it.
