Short answer: Excel and paper are enough for one team, one area and one person who owns the file, and plenty of good lean programs start there. They break when more people, shifts and sites share the same tracker: copies drift apart, nothing chases overdue actions and reports are built by hand. Move to software like LeanSuite when those problems cost more than the tool.
For plants running ideas, kaizen, audits and 5S, daily issues, the skills matrix and SOPs on Excel, SharePoint lists, whiteboards and paper.
