The troubles of employee onboarding
None of the above scenarios are ideal – for the new employee, the recruiting manager, and business operations – yet they still happen too frequently when the onboarding process and its many "splinter" sub-processes are manually intensive. It might be that the sheer complexity of all the moving parts, with multiple business functions needing to do "their bit," causes the issue in terms of the logistics. Or it might be that the immediate lack of urgency for the individual tasks means that they're a low priority in each business function's work pipeline. Unfortunately, some tasks "slip through the cracks" when people are bombarded with a continuous flow of higher priorities. Or it might be that the high level of manual effort is the cause of organizational and provisioning mistakes being made.
As to how common onboarding issues are, a commonly-quoted employee onboarding statistic on the Internet – which is sadly from 2017 but still worth pointing to with an age caveat – is that:
Only "12% of employees strongly agree their organization does a great job of onboarding new employees."

Thankfully, Service Management – the use of IT service management (ITSM) principles, best practice capabilities, and technology to improve business function operations, services, experiences, and outcomes – offers a digital-workflow-based onboarding solution that's commonly one of the first adopted use cases of Service Management within an organization.
