And that is often lacking when an independent professional or interim expert is deployed. Understandable perhaps because the expectation is that temporary professionals add value immediately. Yet research and practical experience show that it is precisely good onboarding that leads to faster productivity, higher engagement and a demonstrably better ROI.
Why onboarding of temporary talent is so important
The idea that temporary professionals "can start working immediately" is partly a myth. Of course they bring experience and knowledge, but without context, clear expectations and access to the right people and resources, organizations lose valuable time.
A structured onboarding provides organizations, among other things, with:
Faster productivity: minder tijd spent searching for information and processes.
Better cooperation: the professional understands the culture and way of working more quickly, and therefore fits better with the team.
Higher quality of output: duidelijkheid about goals and deliverables prevents misunderstandings and rounds of corrections.
Longer and stronger cooperation: tevreden professionals are more likely to accept a follow-up assignment and contribute positively to your employer reputation.
The ROI of good onboarding in numbers
Companies that invest in an onboarding program of several days to weeks find that temporary professionals are on average 20–30% faster to become fully productive. Apply that to a six-month project, and you'll understand how large the financial and qualitative impact can be.
Suppose: an interim project manager of € 100 per hour works 32 hours per week. If that person, thanks to good onboarding, is fully effective one week sooner, your organization quickly saves or earns € 3.200 back in lost time.
And we haven't even mentioned the indirect gains: fewer mistakes, higher satisfaction among stakeholders, and project goals achieved more quickly.
How organizations can approach onboarding smartly
A good onboarding process doesn't have to take weeks. It's about clarity, structure and engagement. Three pillars make the difference:
Sketching context: Explain where the project stands, which goals are important and how the professional contributes to them.
Arrange access: Ensure that systems, documentation and contacts are immediately available.
Sharing culture:Make clear how collaboration takes place, which informal rules apply, and who the main stakeholders are.
Even a one-day onboarding that covers these three pillars significantly speeds up the return.
