Asynchronous Processes: the Next Automation Frontier

An asynchronous process refers to a task or operation that runs independently of the main program flow, allowing other tasks to continue while it executes in the background. Unlike synchronous processes, which block the execution until completed, asynchronous processes enable more efficient use of resources by allowing the program to perform multiple tasks simultaneously or in non-blocking ways. This approach enables a system to handle multiple tasks simultaneously, improving efficiency and responsiveness.

 

1. Key Characteristics of Asynchronous Processes

  • Independent execution: tasks run separately from the main program, often in the background.
  • Non-blocking operations: the primary function continues to run while other processes are executing.
  • Improved performance: by reducing wait times and utilising system resources more effectively.
  • Enhanced responsiveness: applications remain interactive even during long-running tasks.
  • Efficient handling of input and output operations: particularly beneficial for tasks involving waiting, such as file reading or network requests.

Asynchronous processes are especially useful in scenarios where tasks may take an unpredictable amount of time to complete. They allow the system to continue functioning without interruption.

 

2. Everyday Life Examples of Asynchronous Processes

Asynchronous processes are prevalent in many everyday applications, enhancing user experience and system efficiency. Here are some examples:

  • Messaging platforms: Apps like WhatsApp, Slack, and Facebook Messenger use asynchronous processing to send and receive real-time messages without interrupting the user interface. This allows users to continue browsing or typing while messages are delivered in the background.
  • E-commerce websites: Sites like Amazon implement asynchronous processes for features such as live inventory updates, checkout flows, and personalized product recommendations without requiring page refreshes. This creates a more fluid shopping experience.
  • Web browsers: When you download a file in a web browser, the download process runs asynchronously, allowing you to continue browsing other tabs or pages while the file is retrieved.

 

3. Examples in Healthcare

Asynchronous processes in healthcare have become increasingly prevalent, offering numerous benefits for both patients and healthcare providers. Here are some examples of asynchronous processes in healthcare:

  • Remote patient monitoring: Patients with chronic conditions can regularly submit health data, such as peak flow meter results for respiratory issues or symptom severity forms for neurological or rheumatological conditions, allowing providers to track their progress without in-person visits.
  • Specialty care access: Primary care physicians can send patient data to specialists in different locations for review and consultation, enhancing access to specialty care, especially in rural areas.
  • Symptom surveys and triage: Patients can complete symptom questionnaires or interact with AI-powered triage bots before appointments, allowing providers to prioritize and prepare for consultations more effectively.

Any other process that evolves human expert judgement to analyse the patient's data input and then communicate the outcome can also be considered asynchronous. Indeed, one part is gathering the input, which can easily be quantified in terms of effort, but the time it takes to get a response is unknown to the patient.

 

4. Considerations in Automating Asynchronous Processes

Automating asynchronous processes presents key challenges, primarily due to their non-deterministic nature. Operations in asynchronous systems may execute in unpredictable sequences, making it difficult to reproduce bugs and write reliable tests. Concurrency testing is crucial, as multiple threads running simultaneously can lead to race conditions when accessing shared data. Effective resource management is essential to avoid memory leaks, deadlocks, and timeouts from handling many concurrent requests.

To manage these challenges, debugging complexity must be addressed, and scalability testing must be performed to ensure the system can handle high volumes of operations. Mocking and stubbing techniques help simulate asynchronous behaviour, while integration testing verifies how system components interact. 

Robust error handling, performance monitoring, and state management ensure system stability and reliable results. These considerations help improve the reliability and performance of asynchronous processes.

 

In Conclusion: asynchronous processes push the potential of automation

Asynchronous processes enhance the potential of automation by enabling systems to handle multiple tasks concurrently without waiting for each one to finish. This non-blocking behaviour aligns with modern software architectures, allowing automated tests to simulate high-concurrency environments like web servers or APIs. Automation can run tests in parallel, reducing execution time and increasing test coverage. It also enables the validation of interdependent actions across various components, such as database queries and network requests. By automating asynchronous processes, systems can be tested efficiently in dynamic, scalable environments, pushing the boundaries of automation in complex, real-world applications such as in Healthcare and Financial Services.
