In ecommerce, operational scalability demands simplicity. Complex processes typically result in bottlenecks, errors, and miscommunication, stalling growth and inflating costs. For instance, neglecting proper management in refund operations can delay resolution, negatively impacting customer experience and straining fulfillment SLAs. Over time, complexity's burden manifests as teams fail to uphold service levels, driving up costs and eroding efficiency. A preventive operating model includes clear process ownership, defined SLAs, and regular audits to maintain operational simplicity, enabling growth on a sustainable path.
