I worked to reimagine Facebook's supply chain software, buy@, from the ground up. buy@ The promise of buy@ was to optimize Facebook’s spend by providing a centralized and tracked experience where employees can execute procurements and get the gear they need for work. buy@ facilitates $34 billion+ in annual spend, equips 30,000+ employees with the tools they need for work, and is the primary point of interaction between Facebook and tens of thousands of vendors. Done right, buy@ had the opportunity to improve employee's work days, make meaningful impact with its spend, and save Facebook billions. After the first year, adoption was low, cycle times and cost for procurement were unchanged, and customer satisfaction was below 2.5/5. That's where we stepped in. I helped lead a team of 5 product designers and worked with 2 product managers, 1 content designer, an external research agency, 2 engineering managers, 2 Data science partners, and 6 engineers, to redesign the tool over the course of 8 months. The results spoke for themselves.
