Introduction to ZKungFu and Its Challenges
ZKungFu stands as the largest directly operated Chinese food chain in China, renowned for its commitment to healthier food options through steam cooking. With a presence across 600 franchise locations in over 43 cities, it also engages customers through four online third-party food ordering platforms and the Chinese social network WeChat. In 2015, ZKungFu achieved remarkable revenue of 5 billion RMB (approximately 750 million USD). However, operating at such a scale necessitated advanced software solutions for supply chain management, inventory control, daily operations, and corporate accounting.
At that time, ZKungFu relied on proprietary software that failed to meet the growing demands for integrability, flexibility, and scalability. This limitation prompted the company to embark on a significant transformation, opting to rebuild its software infrastructure using open source technologies, including Drupal.
Why Drupal Was Chosen
The decision to adopt Drupal was driven by its flexibility and scalability, making it an ideal fit for ZKungFu's iterative product development approach and decoupled architecture. The challenge of migrating from an outdated proprietary platform to a robust Drupal-based system was daunting, yet the team successfully completed this transition in under a year.
The primary goal was to overhaul ZKungFu's software platform, transforming it from a struggling proprietary system into a Drupal-based solution capable of supporting the company’s extensive operations. The project’s success was marked by rapid progress, and the development team identified three key lessons learned throughout the process.
Lesson One: Deploying Drupal-Based Micro-Services
Drupal's comprehensive capabilities as a business application platform allowed for extensive customization. However, to ensure reliability and scalability, the team opted to implement multiple Drupal sites, creating a network of micro-service providers to support various business functions. This approach enabled faster development, as each micro-service required less knowledge of the entire architecture, allowing teams to work more efficiently.
By dividing functionalities across smaller Drupal sites, the project became more manageable and scalable, particularly under high traffic conditions. Each micro-service could leverage a common set of web services, minimizing the complexity typically associated with distributed data structures for front-end developers.
To illustrate this, three distinct Drupal Commerce sites were established:
- The first site manages product information and branch operations, incorporating pricing rules and variations based on duration, location, and availability.
- The second site focuses on payment processing, handling a significant portion of the company's revenue through QR-Code oriented Alipay and WeChat Pay, alongside other payment methods like cash and credit cards.
- The third site tracks order information, managing the entire lifecycle from order creation to payment, delivery, analytics, and supply chain planning.
In addition to these core functionalities, Drupal was utilized to build marketing, CRM, and ERP capabilities, supporting customer acquisition, loyalty programs, and resource planning.
Lesson Two: Prioritizing Offline Functionality and Reliability
In a business model where the continuous flow of orders and payments is critical, precise data management is essential at multiple levels—device, store, and cloud. To address this, the team designed the POS software with redundancy at all three levels, ensuring offline support was a fundamental requirement.
Recognizing that stable internet connectivity cannot always be guaranteed, the system was engineered so that devices such as cash registers and self-service POS machines could still process orders during connectivity outages. Once the internet connection was restored, the system seamlessly handled multi-level synchronization in the background.
The data infrastructure was built using technologies like CouchDB, PouchDB, Raspberry Pi, Node.js, and Electron, ensuring that critical order and payment data reached Drupal promptly.
Lesson Three: Embracing a Unique Software Development Process
When examining engineering practices, it is evident that Chinese development teams are still evolving to align with global best practices in strategic planning and rigorous methodologies. However, they possess unique strengths, including a focus on products that cater to a large customer base and access to a vast pool of young talent. These attributes enable rapid product iterations driven by empirical evidence.
Throughout the ZKungFu project, new versions of various software components were released daily, facilitated by rotating teams of customers, support staff, and developers working around the clock. The adoption of Drupal's powerful framework and best practices streamlined the onboarding, training, and retention of talent, fostering an environment of continuous innovation.
Conclusion: Empowering ZKungFu Through Open Source
In conclusion, the transformation of ZKungFu's operational capabilities through the implementation of open source technologies and Drupal has set a new standard in the industry. The project not only supports the company's extensive scale but also enables it to manage over one billion dollars in transactions annually. The collaboration among various contributors and the lessons learned throughout this journey have established a robust foundation for future growth and innovation.
