In-House Recruitment Analytics: Addressing Probation Failures

How do you handle probation failure data in your recruitment analytics? My usual approach is to focus on hires made within the last 12 months, but I’m uncertain about how to account for individuals who were hired over a year ago and failed their probation within the past year. Should these cases be excluded, or would it be better to expand the data window? I worry that senior leaders might perceive it as data manipulation if we omit these probation failures, especially since they are aware of recent issues. This can complicate the overall data integrity, as those failures don’t fall within the latest hiring metrics. What strategies do you use to manage this?
