Move scattered SOPs into a living process repository by consolidating current procedures, assigning accountable owners, controlling versions, connecting related processes and evidence, and putting every document on a review cycle. Do not start by uploading every PDF. Start with one process family, prove the governance model, and expand from there.
The best process management software gives teams one living repository for how work runs. It should combine clear process maps with controlled documentation, version history, named ownership, responsibility mapping, evidence, review workflows, and BPMN when formal modeling is needed.
