With smaller companies I would recommend:
– simplify integration approach
– less documentation, use Cloud tolls to support PMI activities (MS teams, SharePoint, SmartSheets, etc.)
– negotiate with management to nominate heads of departments or senior managers of departments (Legal, HR, IT, …) as functional leads for different work-streams
– negotiate with HR to add active collaboration on PMI activities to yearly goals of every employee involved
– use Agile M&A approach
