In-House Recruitment Analytics: Addressing Probation Failures

How do you handle probation failure data in your recruitment analytics? I typically analyze hires from the past 12 months, but I’m unsure how to approach individuals who were hired over a year ago yet experienced probation failures within the past year. Should I exclude them from the data, extend my analysis window, or consider another approach? I worry that senior leaders might perceive data manipulation if these probation failures are omitted. They recall the recent failures, but since those incidents don’t align with the 12-month hiring count, the situation can become quite complex.
