Exploring Systems Thinking for Quality Assurance Professionals

Exploring Systems Thinking for Quality Assurance Professionals

3 July 2024 Stephan Petzl Leave a comment QA

Systems thinking is an invaluable approach for professional testers. It allows you to analyze systems in terms of the relationships and interactions between their components and with other systems, rather than just examining the components in isolation. This holistic approach can significantly enhance your testing strategy and outcomes.

For those new to systems thinking or looking to delve deeper into the subject, there are several key texts that provide comprehensive insights:

  • Introduction to General Systems Thinking by Gerald Weinberg: This book is a seminal work that introduces the fundamental concepts of systems thinking.
  • Quality Software Management, Vol. 1 by Gerald Weinberg: This volume, along with its subsequent volumes, is highly relevant for understanding the application of systems thinking in software quality management.
  • Thinking in Systems: A Primer by Donella Meadows: This book is a great starting point for understanding dynamic systems and their characteristic patterns.

For more resources, you might find valuable reads on The Systems Thinking Review, such as the article “Planting Potatoes the Right Way.”

Practical Applications of Systems Thinking in Testing

Applying systems thinking in your day-to-day testing tasks can be extremely beneficial. Here are some practical ways to incorporate systems concepts:

Understanding System Architecture

Gaining a solid understanding of the system architecture is crucial. Here are some questions to consider:

  • How do the components interact together?
  • What are the relationships between different layers of the system?
  • How tightly are the components coupled?
  • What is the data flow in the system?
  • How are errors propagated through the system?
  • Are libraries shared between different components?
  • What is the relation between the OS and your system?
  • How tightly coupled is the system with the DBMS?
  • How are regional settings and files used within the system?
  • Is the application stateful and how does it affect behavior?

Considering Users as Part of the System

Understanding how users interact with the system can provide valuable insights. Consider asking:

  • How many users can use a functionality simultaneously?
  • Do users receive notifications immediately or through a delayed process?
  • What is the relationship between resource permissions and user privileges?
  • Who are the primary users of a specific functionality, and what are their technical backgrounds?

Leveraging Automation Tools

Incorporating systems thinking into your testing strategy can be further enhanced with the right automation tools. Repeato is a no-code test automation tool for iOS and Android that simplifies the process of creating, running, and maintaining automated tests for your apps. With its computer vision and AI capabilities, Repeato allows you to quickly edit and run tests, making it an excellent choice for quality assurance tasks.
