List requesters, line managers, finance analysts, controllers, budget owners, and executives who interact with each request. Note when each person needs context, how they prefer to be notified, and which decisions require delegation. Clarify responsibilities to avoid ping-ponging tasks, and define how backups step in during vacations. Capture what constitutes a complete request in each role’s eyes so you can design forms and notifications that preempt confusion rather than amplify it.
Real approval paths rarely run straight. Map rules that trigger additional reviews, such as spending above thresholds, new vendors, foreign currency, or gifts. Include special handling for urgent travel, audits, and retroactive approvals. Identify how disputes are resolved and what evidence is required. Understanding these conditions lets you design conditional branches that reflect genuine risk appetite, minimizing manual overrides and preventing shadow processes that undermine trust or create compliance exposure.
Trace where requests originate, which documents accompany them, and how data eventually lands in accounting, ERP, or reporting tools. Note file types, naming conventions, and integration touchpoints like email, spreadsheets, chat, or APIs. Document current bottlenecks such as missing receipts or unclear cost centers. With this map, you can choose platforms that reduce rekeying, preserve accuracy, and provide real-time status visibility across systems without forcing teams to jump between disconnected tools.
