You don't give enough credit to organization chart and project driven engineering. When developing anything: 1) you don't get to touch anyone else's code. And another department's code? Something another manager's team manages ... that amounts to treason. Never for any reason. MAYBE if they've totally abandoned it and you absolutely need it (but only during unpaid overtime) 2) you don't get to spend ANY time on anything outside of the current project or JIRA ticket. Any time at all. So really, NOT optimizing anything is faster and cheaper. Just look at all the spreadsheets made!
