And that's only the main process without details.
Developers also appreciated my initiative. When I formulate the task in Jira I attach the scheme of a process related and explain what should be changed and how. Considering that we speak Spanglish that is not native to anyone in the team, images help communication a lot.
I publish schemes to Confluence
where e store all documentation. When a process change – I add a new scheme with an update date and store the previous one for the history in order to be able to answer question like "When have we changed this thingy?". Developers and managers have an access to Confluence so they can check it any time they have questions.
I found out an interesting side effect – other guys from the company started to use the same approach for their processes. Sometimes I see finance or sales guys drawing schemes in Miro.
