There is a little known saying that goes, “Just because you’ve counted all the trees doesn’t mean you’ve seen the forest”. In software development, counting the trees would be analogous to testing and seeing the forest akin to load testing the entire application; see if it is built to deliver.
In a modern fulfillment center, with the high number of integration touch points between hardware and software, exploding number of selling channels, and increased pressure to deliver at speed, performance testing has started to take significance like never before.
The performance of these solutions like Order Management (OMS) and Warehouse Management (WMS) directly impacts the operational efficiency of the fulfillment operations. Performance issues remain hidden during non-peak seasons when business is operating at lower volumes. The real issues show up only when the business is fulfilling at peak capacity. Any issues during peak impacts the ability of the business to meet fulfillment SLAs, which in turn impacts customer confidence.
Why Performance Testing Matters
Identifying Bottlenecks:
At Undocked, we emphasize the importance of performance testing to uncover inefficiencies that could slow down operations, particularly during peak periods like the holiday season. By simulating high-demand scenarios, businesses can pinpoint where their systems are likely to falter and take pre-emptive action to rectify these issues.
Optimizing Resource Utilization:
Effective performance testing ensures that systems are using resources efficiently. This means evaluating how systems handle different loads and transactions, thereby optimizing the use of hardware, software, and network resources. This lets the team reduce the costs by avoiding over-provisioning of the resources.
Ensuring Scalability:
Scalability is a critical aspect of modern supply chain systems.
Performance testing helps verify that systems can scale up to meet increased demand without compromising performance. For OMS, WMS, and TMS solutions hosted on the cloud, and although cloud environments are designed to scale on the fly, it is still prudent to ensure resources are utilized efficiently under load. Performance testing assures business teams that the OMS, WMS and TMS solutions can scale efficiently without degrading performance even during growth or seasonal spikes in activity.
Reliability:
Ensures that the supply chain systems maintain consistent performance levels, providing reliable service to users even during high traffic periods.
Benchmarking:
Supply chain systems like OMS, WMS and TMS are intricately tied to order fulfilment efficiencies. Performance testing provides visibility into any delays and throughput issues that the operations team might experience during peak periods. It can be used to set performance improvement goals over time and offers benchmarks at different resource provisioning levels. This allows the business to make informed decisions about resource allocation during peak and non-peak periods, ensuring optimal performance and cost efficiency.
Key Steps for Effective Performance Testing
Define Test Objectives:
At Undocked, we help businesses determine what aspects of performance to evaluate, such as response times, throughput, and resource utilization. Clear objectives guide the testing process and ensure all critical performance aspects are covered.
Identify Systems Landscape and Timelines:
Consider the implementation schedule and infrastructure. This helps in strategizing how systems will be hosted, maintained, and upgraded.
Define Performance Metrics:
Key metrics like response times, transaction rates, CPU and memory usage, and network latency should be identified and monitored during testing. These metrics provide a comprehensive view of system performance.
Create Realistic Test Processes:
Develop test scenarios that mimic real-world usage. This includes how different end-users interact with the system and the most resource-intensive processes.
Scale Test Processes and Data to Predicted Future Loads:
Ensure the system can handle future growth by scaling test processes and data to projected load levels. This helps in futureproofing the system.
Align Various Infrastructure Teams:
Collaboration among infrastructure teams (IT, database administrators, cloud engineering, etc.) is essential. This ensures that all aspects of the system are tested and optimized.
Execute Testing and Collect Results from All Sources:
Perform comprehensive testing and gather data from all relevant sources. This holistic approach ensures no aspect of the system's performance is overlooked.
Analyze, Diagnose, and Repeat:
Continuous analysis and iteration are key. Review test results, diagnose issues, and refine the system. This iterative process ensures ongoing performance improvements.
Practical Insights from Undocked
Real-Time Monitoring:
Implementing real-time monitoring and alerting systems can provide immediate feedback on system performance, allowing for rapid response to any issues that arise.
Automation:
Automation of performance tests can significantly speed up the testing process and ensure consistency. Automated tests can be run frequently to catch performance issues early.
Continuous Improvement:
At Undocked, we advocate for a culture of continuous improvement. Regularly update and refine testing processes based on the latest performance data and evolving business needs.
