Interview Prompt
We produce 30 million custom print products a year for small businesses - business cards, flyers, and banners - each one unique. Our profitability depends on ganging: combining multiple customer orders onto a single press sheet to maximize utilization. The ganging algorithm needs a real-time view of pending orders, and our operations team needs to know before a job starts whether it will meet its delivery promise. Our analytics are also fragmented across 10 acquired companies running different ERP systems. Design a pipeline that supports all three needs.
Summary
One press run, many orders. Group them right.
