Start with the work, not the software menu
Before changing fields or installing apps, write down the actual flow: who starts the work, what information is needed, who approves it and what result closes the loop.
Keep the first map small
A useful first version usually has a start, five to ten process steps, decisions, documents and handoffs. That is enough to expose unclear ownership and repeated manual work.
Use the map to guide configuration
Once the process is visible, Odoo configuration becomes more precise. The team can decide what stays standard, what needs training and what genuinely needs automation.
