Hi Danielle,

Start the planning with prioritising the standardised process for knowledge management, with clearly defined roles and responsibilities and templates for different processes to show quick wins to show adoption.

Engage process owners and process managers to design and automate the process along with creating content using proper keywords to make them easily searchable for the users.

Plan surveys to collect the feedback from end users and all other stakeholders to improve the content and ask them to review the content and rate it and based on the rating try to show up top 5 articles for every search.

I hope this will work.

Regards,

Sonal
