The CobWeb Theory as it applies to QA

CobWeb Therory QA

The CobWeb Theory is a concept that was first proposed by economist Thomas Schelling in the 1960s. It is a model that helps to explain how seemingly small and insignificant changes in a system can lead to large and significant changes over time.

In the context of Quality Assurance, the CobWeb Theory can be used to explain how small deviations from quality standards can lead to larger deviations over time. For example, if a manufacturing process begins to produce products that are slightly out of spec, this may not be immediately noticeable. However, over time, as more and more products are produced with these small deviations, the overall quality of the products will degrade.

The key takeaway from the CobWeb Theory is that small deviations from quality standards can have a significant impact over time. This is why it is important to have a robust Quality Assurance system in place that can detect and correct small deviations before they become larger issues.

One of the ways to do this is through the implementation of continuous improvement processes such as Six Sigma, Total Quality Management, etc. These methodologies are based on the principles of data-driven decision-making, and they provide a framework for identifying and eliminating sources of variation in a process. By using data to drive decision-making, organizations can more effectively detect and correct small deviations from quality standards, preventing them from becoming larger issues.

Another effective way to prevent the CobWeb Theory from happening is through regular audits, inspections, and testing of products, services, and processes. These activities can help identify and correct deviations from quality standards before they become larger issues. Additionally, regular training and development of employees is also important, as it helps to ensure that everyone is aware of the importance of quality and is equipped with the necessary knowledge and skills to uphold quality standards.

In conclusion, the CobWeb Theory highlights the importance of having a robust Quality Assurance system in place, one that is able to detect and correct small deviations from quality standards before they become larger issues. By following continuous improvement processes, regular audits, inspections, and testing, and regular training and development of employees, organizations can ensure that they maintain high quality standards and prevent the CobWeb Theory from happening.

Spring Training

Spring Training Q A

Software Quality Assurance (SQA) can be compared to baseball spring training in several ways:

  • Preparing for the season: Just as baseball teams use spring training to prepare for the upcoming season, SQA teams use this time to prepare for the release of a software product. This includes setting up the testing environment, defining testing strategies, and creating test cases.
  • Building teamwork: Spring training provides an opportunity for players to come together as a team, and SQA teams must also work together to ensure that all aspects of testing are covered. This includes collaborating on test plans, sharing test results, and working together to identify and resolve defects.
  • Practicing fundamentals: During spring training, players focus on the basics of the game such as hitting, fielding, and throwing. Similarly, SQA teams focus on the fundamentals of testing, such as creating comprehensive test cases, conducting thorough regression testing, and verifying that defects have been resolved.
  • Identifying strengths and weaknesses: In baseball, spring training is a time for coaches to assess the strengths and weaknesses of each player. Similarly, SQA teams use this time to identify the strengths and weaknesses of the software product, such as which areas of the application are most susceptible to defects.
  • Iterative improvement: Finally, just as players use spring training to improve their skills, SQA teams use this time to improve the testing process. This includes implementing new testing tools, refining test plans, and incorporating lessons learned from previous releases.

In conclusion, SQA is like baseball spring training in that it provides an opportunity for teams to prepare for the upcoming season, build teamwork, focus on the fundamentals, identify strengths and weaknesses, and improve through iterative refinement.

Stealth Mode Deployment vs Release Canaries

Release Canaries and Stealth Mode Deployment are both software development and deployment strategies that aim to minimize the risk of introducing issues or negative impacts to the user base. However, they differ in their approach and execution.

Stealth Canaries

Key Features

Release Canaries involve releasing a new version of software to a small subset of users or servers before rolling it out to a wider audience. The Canary is used to test the new release in a real-world environment and identify any potential issues before the release is made available to everyone.

Stealth Mode Deployment, on the other hand, involves gradually rolling out changes or new features to a small subset of users and monitoring the impact of those changes before rolling them out to a wider audience. The changes are not explicitly announced, and the focus is on making incremental changes that can be tested and monitored.

Key Differences

While both strategies aim to reduce the risk of introducing issues or negative impacts to the user base, release canaries are generally used for major releases, while Stealth Mode Deployment is more commonly used for incremental changes or feature rollouts. Release Canaries are also typically used in situations where there is a higher risk of introducing critical issues or where the user base is large and diverse, while Stealth Mode Deployment can be used in situations where the changes are less critical or the user base is smaller.

In summary, both Release Canaries and Stealth Mode Deployment can be effective strategies for minimizing risk and improving the quality of software releases. The choice of which strategy to use depends on the specific circumstances and goals of the release, as well as the size and diversity of the user base.

Stealth Mode Deployment

Stealth Mode Deployment 2023

"Stealth mode deployment" is a software development and deployment strategy where new features or changes are rolled out gradually and without fanfare. Instead of making a big announcement or releasing a new version with all changes at once, changes are released incrementally to a small subset of users and monitored for issues before being rolled out to a wider audience.

The idea behind stealth mode deployment is to minimize the risk of introducing bugs or issues that could impact the entire user base. By rolling out changes to a small group of users, developers can test and monitor the changes in a real-world environment, identify and fix issues as they arise, and gradually increase the number of users who have access to the changes.

Some benefits of stealth mode deployment include:

  • Reduced risk of issues impacting the entire user base: By releasing changes to a small subset of users first, any issues that arise can be caught and addressed before they impact a larger number of users.
  • Incremental testing and monitoring: By rolling out changes gradually, developers can test and monitor changes in a real-world environment and address any issues as they arise.
  • Improved user experience: By gradually rolling out changes and monitoring their impact on user behavior and experience, developers can ensure that the changes are positively received by users.
  • Increased confidence in deployment: By testing and monitoring changes before they are rolled out to a wider audience, developers can have increased confidence that the changes are stable and will not negatively impact the user base.

In summary, stealth mode deployment is a software development and deployment strategy that can help minimize the risk of introducing issues and improve the user experience. By rolling out changes gradually and monitoring their impact, developers can identify and address issues before they impact a wider audience and increase their confidence in the deployment process.

Release Canaries

Release canaries are a technique used in software development and deployment that can help ensure the quality and stability of a release. Essentially, a release canary is a small subset of users or servers that receive a new release before it is rolled out to the wider audience. The canary is used to test the new release in a real-world environment and identify any potential issues before the release is made available to everyone.

Canaries Testing

Here are some ways that release canaries can save your bacon for QA:

  • Early detection of issues: By releasing a new version to a small subset of users or servers, you can quickly identify any issues that may arise with the new release. This allows you to address any problems before the release is made widely available, potentially preventing widespread issues that could negatively impact user experience.
  • Reduced risk: By releasing a new version to a small group of users or servers, you reduce the risk of a major issue affecting the entire user base. If an issue is identified during the canary release, you can easily roll back the changes and prevent any widespread issues. This strategy makes it easier to detect any problems with the new version, as the impact is limited to a small group of users or servers. This allows you to address the issue before it affects the entire user base, thus reducing the risk of any widespread disruptions.
  • Improved feedback: Release canaries allow you to receive feedback from a smaller group of users or servers, which can be more manageable and easier to analyze. This feedback can be used to make improvements to the new release and ensure that it is ready for wider release. By using release canaries, companies can gradually roll out a new version to a small group of users or servers and monitor their response. This allows them to make adjustments and improvements to the new version before releasing it more widely. It also helps to identify any potential problems that could arise before they become widespread.
  • Increased confidence: By testing a new release on a smaller scale before making it available to everyone, you can have increased confidence in the quality and stability of the release. This can give your team peace of mind that they are delivering a high-quality product to users. By testing the product on a smaller scale, you can identify any potential issues before they become widespread and can make the necessary changes before rolling out the product to the public. This can save your team time and money by preventing potential problems and ensuring customers receive the highest quality product.

In summary, release canaries can help to identify potential issues early, reduce risk, improve feedback, and increase confidence in a new release. Incorporating release canaries into your quality assurance process can be an effective way to ensure that you are delivering a high-quality product to your users.

January Retrospective

At the start of a new year, it's critical to take a look back at the Quality Assurance process of the previous year. This will enable you to see what worked well and what areas need improvement.

Doing this will help you identify any areas of weakness in the QA process that could have been addressed earlier. It will also provide an opportunity to evaluate the effectiveness of the strategies and techniques employed in the QA process. This will enable you to make any necessary changes before the start of the new year.

This retrospective focuses on January 2023.


January 2023 saw the implementation of a redesigned QA process that focused on automation and collaboration between teams. This process allowed for faster feedback and increased efficiency in the QA process.

As a result, QA teams were able to identify and address issues more quickly, resulting in improved product quality and shorter release cycles. The updated process also enabled teams to collaborate more effectively, allowing them to share best practices and insights across teams.


One of the main challenges with the redesigned process was the lack of documentation and clear communication between teams. This led to confusion and delays in the QA process. For example, the development team might have begun working on a feature without knowing the exact specifications from the product team. This led to delays when the product team had to review the work.


In order to address the issues with documentation and communication, a revised system was implemented that provided a more organized approach to communication and documentation. This system allowed for faster resolution of issues and better overall collaboration.

The updated system provided a centralized place to store all communication and documents related to a project, which enabled team members to access the information they needed more quickly. This also allowed for better tracking of progress, so that any issues could be identified and addressed more quickly.


Overall, the revised QA process implemented in January 2023 was a success. The updated system for documentation and communication allowed for better collaboration between teams and improved the overall QA process. As we move into the new year, we look forward to continuing to improve our QA process.

As Therone Shellman once wrote: 'It's not so much what you accomplish. But what's more relevantnt is how far you've come to accomplish what you have. Success is the measure of not mere achievement, but also how hard one had to work.'
