Definition
Average lead time of completed (non-cancelled) instances of the joiner process during the period.
Components
Lead Time | The amount of time between the joiner hire notification time and the joiner start time. |
|---|---|
Completed (non-cancelled) instance | A process instance that has been completed but not cancelled (i.e. the joiner effectively joined the organization). |
Joiner Process | |
Period | The period being analyzed, depends on the indicator reporting frequency but typically monthly or weekly. |
Rationale
This indicator gives a sense of the amount of time available to the IAM function to assure that the joiner’s identities and accesses will be operational at start time.
When compared with similar organizations, this indicator may reveal some aspects of the organization’s culture.
Limitations
Averages are hiding the underlying distribution and its dispersion.
First, it may be necessary to look at different populations (e.g. contractors versus employees) that may have different onboarding constraints and lead times to optimize the joiner process.
Second, low and high variances could both lead to the same average lead times but would be a completely different story in terms of managing the joiner process.
Finally, the successful onboarding of workforce members may require contributions from multiple stakeholders within the organization (e.g. HR, Logistic, Procurement, etc.). Trying to optimize the organization workforce onboarding process by only looking at the IAM joiner process may be insufficient.
Formula
Let P = (pstart, pend) be the period of time being analyzed with pstart the period start time and pend the period end time.
Let I be the set of completed (non-cancelled) joiner process instances whose joiner start date were within P.
Let n = |I| be the number of joiner process instances in I.
Let H = h1, h2, h3, …, hn be the set of hire notification times of I.
Let S = s1, s2, s3, …, sn be the set of start times of I.
The formula for the indicator is then: y = .
