Hi all! Looking for some examples of how organizations handle high volume of onboarding new IT team members!

The organization I'm with has been busy with expanding our IT team over the past couple years and there are no signs of slowing down. To accommodate our recruitment, we speed through a blend of ILT sessions for the employee basics (product training, soft skills, etc.), 1:1 sessions for role/department specific, and reviewing resources (mostly Wiki.) We also work in plenty of culture building content to ensure they connect with the organization.

Their first three weeks are typically a blend of the above, self exploration, and guidance from their manager. This works for most team members, but we've started to see the occasional new team member run into challenges. One of the areas that we are starting to see some challenges in is the knowledge transfer of legacy coding, concepts, and org specific adaptations of skills (e.g. programming.) Folks come in with expertise in an area and have difficulty calibrating that expertise to the organization's approach to that area.

The other part is the reliance on a Wiki for new team members to learn. With the high volume of onboarding, we have noticed a trend of SME's referring new team members to Wiki pages instead of 1:1 education sessions. These Wiki pages can be hard to find and potentially out of date.

Overall, it seems like the volume of onboarding is leading to a less consistent onboarding experience for newbies. 

I'm curious if anyone would be open to sharing a general overview of their organization's approach for high volume IT onboarding as well as any suggestions on how knowledge is stored/maintained!

Thanks in advance!
