What is reactive and proactive testing

Software quality management is a critical aspect of the development life cycle that involves ensuring that software meets desired quality standards. Reactive and proactive methods can be used to manage software quality.

Reactive methods involve dealing with problems after they have been found, such as thorough testing after development, responding to customer complaints, and addressing missed problems. Although these methods can solve immediate problems, they are often less effective and more costly in the long term, causing delays and dissatisfied clients.

In contrast, proactive methods aim to prevent problems before they arise, such as through establishing quality standards and testing throughout the development process. Proactive methods can be more effective because they prevent issues and ensure software development meets quality standards. Additionally, proactive methods can shorten development cycles by identifying and fixing issues early in the process.

Proactive Approach:

Agile Methodology:

Agile methodology is a flexible and collaborative software development approach that prioritizes delivering high-quality software quickly and efficiently. It is particularly useful during a pandemic, allowing teams to adapt to rapidly changing circumstances such as remote work and shifting project priorities. Scrum is a popular agile methodology that involves time-boxed sprints for planning and delivering work in short cycles.

Daily stand-up meetings, sprint reviews, and retrospectives enable frequent communication, feedback, and continuous improvement. Kanban involves a continuous flow of work items through a visual board with columns representing different stages of work. Both Scrum and Kanban emphasize collaboration, continuous improvement, and delivering working software quickly and efficiently. Agile methodologies enable teams to remain flexible and responsive to changing needs, making them effective approaches for software development during a pandemic or other dynamic situations.

Test Driven Development (TDD):

Test-driven development (TDD) is a software development methodology that prioritizes creating automated tests for software functionality before writing any actual code. The TDD process begins with the developer writing test cases that define the anticipated behavior of the software, including inputs, expected results, and error conditions. Then, the developer writes the minimum amount of code required to pass the tests, known as the "production code." If a test fails, the developer modifies the production code until the test passes. This process is repeated for each test case.

TDD provides several benefits, including early detection of defects and design flaws, as issues can be identified and resolved before the code is written. It also helps ensure that the software meets precise requirements and performs as expected. Additionally, TDD promotes modular and reusable code, resulting in higher code quality. The test suite created through TDD can also be useful in identifying regressions or unintended effects during future codebase changes. Overall, TDD is a proactive approach to software development that emphasizes code quality, early defect detection, and adherence to requirements.

Tools and Cost

Junit and Nunit are popular open-source testing frameworks that can be used for Test-Driven Development (TDD). These frameworks provide a set of tools for creating and running automated unit tests.

JUnit is a testing framework for the Java programming language. It is widely used by Java developers and provides a simple and easy-to-use interface for writing unit tests. JUnit tests can be run automatically, which makes it a popular choice for Test-Driven Development.

NUnit is a testing framework for .NET programming languages such as C# and VB.NET. It is similar to JUnit and provides a set of tools for creating and running automated unit tests. NUnit is also open-source and has a large and active community of developers.

Both of these testing frameworks are free and open-source, which makes them accessible to developers and teams of all sizes. The cost of using these frameworks mainly depends on the time and resources required to implement Test-Driven Development in the development process. However, the benefits of TDD can be significant in terms of reducing the time and cost of fixing bugs and ensuring that the software meets specific requirements.

Continuous Integration (CI) and Continuous Delivery (CD):

Continuous Integration (CI) and Continuous Delivery (CD) are techniques used by software developers to improve software quality and accelerate software updates. CI involves integrating code changes into a shared repository, allowing for quick identification and resolution of conflicts or issues. Automated tests are run as part of CI to ensure code adherence to quality standards and proper integration with other changes.

CD takes CI a step further by automatically deploying code changes to a production or production-like environment, ensuring swift and bug-free deployment. Additional testing, such as speed or security testing, can be included in CD pipelines to thoroughly examine code changes before release. CI/CD pipelines may also include steps such as building and packaging software, code analysis, and quality checks, which are automated and reduce the need for manual testing.

One of the key benefits of CI/CD is early detection of flaws in the development process, allowing for quick fixes before impacting end-user experience. It also promotes a culture of continuous improvement, enabling developers to receive feedback and make necessary corrections, resulting in higher quality software that meets customer requirements. CI/CD streamlines development processes, saves time and effort, and helps ensure software quality through automated testing and deployment. Overall, CI/CD techniques enhance software development by catching issues early, reducing errors, and improving the overall quality of the software.

Tools and Cost

Jenkins and CircleCI are all examples of CI/CD tools that can be used to implement continuous integration and delivery practices in software development.

CircleCI provides a wide range of features, including automatic parallelization, caching, and auto-scaling, making it a popular choice for teams of all sizes. CircleCI is available in both free and paid versions, with pricing based on usage.

Code Review:

Code review is a crucial procedure in software development that involves reviewing and verifying other developers' source code for accuracy, effectiveness, maintainability, and scalability. It is typically conducted before merging the code into the main branch or making it available for use to minimize the introduction of bugs or problems into the codebase.

There are various methods for conducting code reviews, including pair programming, pull requests, and formal code walkthroughs. Pair programming involves two developers collaborating in real-time, with one writing the code while the other reviews it. Pull requests involve one developer submitting their modifications to the codebase, which are then reviewed and commented upon by other developers. Formal code walkthroughs entail a team of developers reviewing the code together and providing feedback.

Code reviews offer several advantages, including early detection of flaws in the development process, improved scalability and maintainability of the code, opportunities for knowledge exchange among team members, and identification of potential security flaws. Additionally, code reviews ensure that the code adheres to best practices and coding standards, making it easier for future developers to maintain and update the code. Overall, code reviews are an essential step in the software development process to ensure the quality and reliability of the code.

Tools and Cost

Paid plans with additional features and storage are available for larger teams or organizations, and the costs vary depending on the plan and the number of users.

Automated Testing:

Automated testing is a method of leveraging software tools to automatically test software features and ensure they are operating as intended throughout the software development process. Test scripts are used to simulate user interactions with the software, and the expected results are compared to the actual results to identify any flaws or errors. From unit testing, which involves isolating and testing individual blocks of code such as functions or methods, to end-to-end testing, which tests the complete software application including user interfaces, business logic, and data storage, automated testing can be used to ensure the software functions properly.

Unit testing is the most basic type of automated testing and is typically performed by developers. It involves testing smaller pieces of code to ensure they are functioning properly, and unit tests are usually written and run whenever changes are made to the code. Integration testing, on the other hand, examines how different pieces of code interact with each other to confirm their proper functioning as a whole. Automation tools can simulate the integration of code components and verify their interactions, making it easier to detect defects that may arise during communication between components. End-to-end testing, which uses software tools to simulate user interactions and verify the application's performance as expected, ensures that the software meets specifications and delivers value to users by testing the complete software application. Overall, automated testing is a critical approach in software development to ensure software quality and reliability. By automating different types of testing, developers can catch defects early, streamline the testing process, and deliver high-quality software to end-users.

However, there may be costs associated with training and support if needed.

Early detection and surveillance

A proactive approach to avoiding and managing pandemics is early detection and surveillance. While surveillance entails ongoing monitoring and reporting of possible outbreaks, early detection focuses on spotting and tracking unusual disease patterns. Monitoring for unusual disease trends is one method for early pandemic detection. Public health organizations can monitor the prevalence of illnesses and syndromes and search for odd trends that could point to an outbreak. For instance, a rise in respiratory illnesses during the summer could indicate the emergence of a new respiratory virus. Similar to human populations, animal populations can be monitored to detect possible disease outbreaks before they affect people.

The development and implementation of diagnostic tests is another crucial component of early detection and surveillance. Rapid diagnostic procedures can aid in determining the origin of an outbreak rapidly and enabling targeted interventions. For instance, diagnostic tests can assist in differentiating between viral and bacterial infections, each of which calls for a unique course of therapy. Case monitoring and reporting are crucial for surveillance and early detection. Public health organizations can investigate and act swiftly to stop the spread of a disease when they learn about unusual disease patterns or outbreaks. Case reporting assists in identifying high-risk populations and focusing measures to stop the spread of disease.

Tools and Cost

Disease surveillance systems collect and analyze data on disease patterns, symptoms, and transmission rates to identify potential outbreaks. They may involve electronic health records, laboratory data, and other sources to track and detect diseases early.

Rapid and accurate diagnostic tools, such as polymerase chain reaction (PCR) tests or antigen tests, can help in early detection of infectious diseases, including pandemics.

The costs associated with early detection and surveillance methods may vary depending on the specific tools and technologies used, as well as the scale of implementation. Costs may include investment in surveillance systems, procurement of diagnostic tools and tests, training of personnel, data analysis, and reporting.

Vaccination

One of the most effective ways to stop pandemics is through vaccination, which is a proactive strategy to stop the spread of infectious illnesses. The way vaccines function is by encouraging the body's immune system to create antibodies that combat a particular disease. Once immunized, a person has a lower risk of contracting the illness and, in the event that they do, are more likely to experience milder symptoms. To guarantee the safety and effectiveness of vaccines, extensive testing, research, and clinical trials are required. When creating vaccines, scientists either use bacteria or viruses that have been weakened or rendered inactive or they use a portion of the bacteria or virus that causes an immune reaction. Vaccination campaigns are used to spread vaccines to the general population after they have been created.

Pandemic risk can be decreased by giving vaccines to groups who are at risk. Herd immunity, an occurrence that is brought about by immunizing a significant portion of the populace, is accomplished. When a sizable percentage of a population is immune to a disease, herd immunity occurs, which reduces the likelihood that the disease will spread to those who are not immune. This helps to safeguard people who cannot get vaccinations for medical reasons like hypersensitivity or immunodeficiency conditions. Vaccination can be a vital weapon in pandemic situations to stop the disease from spreading. For instance, the COVID-19 pandemic sparked the rapid creation and introduction of vaccines that were incredibly successful at reducing the spread of infection and the severity of illness. Vaccination campaigns were critical in reducing the spread of the disease and minimizing its impact on society.

Tools and Cost:

Vaccines are biological preparations that contain weakened or inactivated forms of the disease-causing agent, which stimulate the immune system to produce immunity against the disease. Vaccines need to be distributed and administered to the target population, following appropriate protocols and guidelines.

The costs associated with vaccination efforts include research and development of vaccines, manufacturing and production, distribution, administration, and monitoring of vaccine safety and effectiveness.

Public health education and awareness

An essential proactive strategy for preventing the spread of infectious diseases, including pandemics, is public health education and knowledge. Increasing knowledge and awareness, promoting healthy behaviors, and preventing the spread of disease can all be achieved by educating the public about the risks and preventive steps related to pandemics. Public health education and awareness campaigns can be carried out in a variety of methods. Public health initiatives can be created to spread knowledge about a particular pandemic or to encourage healthy habits. Community outreach initiatives can be used to inform people and their families about the dangers of pandemics and the steps that can be taken to stop the spread of disease. Additionally, social media can be an effective tool for spreading pandemic knowledge and encouraging healthy lifestyles.

Campaigns for public health instruction and awareness can concentrate on a variety of subjects, including sanitation of the hands, respiratory etiquette, mask use, social distancing, and vaccination. For instance, public health campaigns were used during the COVID-19 pandemic to increase awareness of the value of wearing masks and keeping social distance to stop the virus from spreading. Additionally, brochures and posters with instructions on how to encourage healthy habits and stop the disease from spreading were distributed. Effective public health education and awareness campaigns are created to be available to all members of the community, regardless of their age, language proficiency, or literacy level, and to be culturally appropriate. The most crucial information should be the emphasis of messages, which should be clear, concise, and actionable.

Tools and Cost

Information campaigns use various communication channels, such as social media, websites, print media, and public service announcements, to disseminate information about the disease, its transmission, and preventive measures. Health literacy programs aim to improve individuals' knowledge and understanding of health-related information, empowering them to make informed decisions about their health and follow preventive measures.

The costs associated with public health education and awareness campaigns may include designing and implementing communication strategies, creating educational materials, and conducting health literacy programs.

Border control measures

In order to stop the spread of infectious diseases across the world, border control measures are a collection of proactive techniques. Travel restrictions, quarantine requirements, and health inspections are some of these steps. Measures to control border crossings are crucial for avoiding pandemics because they can lessen the importation of infectious diseases from other nations.

Travel restrictions are a frequent border control strategy used to curtail cross-border movement of people. Travel to certain nations may be temporarily prohibited, high-risk passengers may need to stay in quarantine, and visa requirements may also apply. Limiting the number of people who interact with each other in various areas can help to slow the spread of infectious diseases.

Individuals who have been exposed to a contagious illness but have not yet exhibited symptoms must be quarantined. Travelers from high-risk regions or people who have come into touch with someone who has tested positive for an infectious disease may be subject to mandatory quarantine. By limiting contact between those who are ill and the general public, quarantine aids in the prevention of illness. When someone enters a country, their health is evaluated through health screenings, which also entail taking their temperature and learning about recent travel experiences. Health examinations can aid in identifying potential carriers of infectious diseases and deter them from joining the nation.

Collaboration between nations and overseas entities is required for the effective implementation of border control measures. To be successful in stopping the spread of infectious diseases, these measures should be supported by strong scientific proof and coordinated with public health initiatives.

Tools and Cost

Travel restrictions include measures such as travel bans, limitations on entry or exit, mandatory quarantine or isolation periods for travelers, and health screenings at border checkpoints. Immigration controls measures can include visa requirements, health certifications, and health screenings for immigrants and refugees. Customs and trade controls measures can include inspections of goods and cargo, import/export restrictions on items that may pose a health risk, and sanitary inspections of food and agricultural products.

The costs associated with implementing border control measures can vary depending on the extent and duration of the measures, as well as the resources required for enforcement, such as personnel, equipment, and infrastructure. These costs can include expenses for staffing, training, equipment, logistics, and administrative overhead.

Treatment of infected individuals

Social distancing and crowd control measures

Enhanced surveillance and monitoring

Debugging

Debugging is an essential step in reactive software quality management. It helps developers to identify and fix defects in the software code. Debugging can be done manually by developers or with the help of debugging tools. Manual debugging involves developers going through the code line by line and using print statements or log messages to identify the source of the problem. This can be time-consuming and error-prone, especially for complex software applications.

Debugging tools can help to simplify and speed up the debugging process. Some common debugging tools include:

GDB is a popular debugging tool used by developers to debug C, C++, and Fortran code. It allows developers to examine and manipulate the state of the program during execution, set breakpoints, and step through code one line at a time. GDB is available for multiple operating systems and is open source.

Visual Studio Debugger is a debugging tool for Microsoft Visual Studio. It allows developers to debug code written in multiple languages, including C++, C#, and VB.NET. It offers a range of debugging features, including stepping through code, setting breakpoints, and inspecting variables.

Eclipse Debugger is a debugging tool for the Eclipse IDE. It supports multiple programming languages, including Java, C++, and Python. It offers a range of debugging features, including stepping through code, setting breakpoints, and inspecting variables.

The cost of debugging tools varies depending on the tool and the licensing model. Some tools, like GDB, are open source and free to use, while others, like Visual Studio Debugger, require a paid license. The cost of manual debugging is mainly the developer's time and effort, which can be significant, especially for complex software applications.

Testing

Testing is a critical aspect of reactive software quality management, and it involves executing software code to identify defects. Manual testing involves executing the software and manually checking for defects, while automated testing involves running tests automatically with the help of testing tools. Automated testing tools can help to identify defects quickly and accurately, reducing the time and effort required for testing.

Some common automated testing tools include Selenium and JUnit.

Selenium is a popular open-source automated testing tool for web applications. It allows developers to write test scripts in multiple programming languages such as Java, C#, Python, and Ruby. Selenium can be integrated with other testing tools such as TestNG, JUnit, and NUnit. Selenium can also be integrated with popular browser automation tools such as BrowserStack and Sauce Labs. The cost of Selenium varies depending on the size of the organization and the level of support required. Selenium itself is free and open-source, but organizations may choose to pay for support services or additional features provided by third-party vendors.

JUnit is a widely used open-source unit testing framework for Java programming language. It allows developers to write and execute test cases for individual code components such as methods and classes. JUnit provides a range of assertions and annotations to simplify the process of writing and executing test cases. The cost of JUnit is free, as it is open-source software.

Root cause analysis

Root cause analysis (RCA) is a method used in reactive software quality management to identify the underlying cause of a defect and address it to prevent similar defects from occurring in the future. RCA involves a systematic approach to problem-solving that aims to get to the root cause of a problem, rather than just addressing the symptoms. The goal of RCA is to prevent the same problem from occurring again in the future, rather than just fixing the immediate issue.

There are several steps involved in conducting a root cause analysis:

• Define the problem: The first step in conducting an RCA is to define the problem. This involves identifying the symptoms of the problem and determining the scope of the issue. For example, if the problem is a software crash, the symptoms might include an error message, a system freeze, or a reboot.
• Collect data: The next step is to collect data about the problem. This can involve examining system logs, user reports, and other sources of information to determine what happened leading up to the problem. This information can help to identify potential causes of the problem.
• Analyze data: Once the data has been collected, it is analyzed to determine the root cause of the problem. This involves examining the data to determine what caused the problem to occur. For example, if the problem was caused by a memory leak, the analysis might involve examining memory usage data to determine where the leak occurred.
• Identify solutions: Once the root cause of the problem has been identified, the next step is to identify potential solutions. This might involve making changes to the software code, system configuration, or other aspects of the system. The goal is to find a solution that will prevent the problem from occurring again in the future.
• Implement solutions: The final step is to implement the identified solutions. This might involve making changes to the code, updating system configurations, or providing additional training to users. The goal is to implement solutions that will prevent the problem from occurring again in the future.

There are several tools that can be used to conduct a root cause analysis. These include:

• Fishbone diagram: A fishbone diagram is a tool used to identify the root cause of a problem. It involves identifying potential causes of the problem and then mapping them out on a diagram. This can help to visualize the potential causes of the problem and identify the most likely root cause.
• 5 Whys: The 5 Whys is a technique used to identify the root cause of a problem by asking "why" questions. This involves asking a series of questions to get to the root cause of the problem.
• Ishikawa diagram: An Ishikawa diagram is a tool used to identify the root cause of a problem. It involves identifying the problem and then mapping out the potential causes of the problem. This can help to visualize the potential causes of the problem and identify the most likely root cause.

The cost of conducting a root cause analysis can vary depending on the size and complexity of the problem being addressed. It can be time-consuming to collect and analyze data, and it may require additional resources to implement solutions. However, the cost of not conducting a root cause analysis can be even higher, as it can lead to recurring problems and impact the overall quality of the software product.

Treatment of infected individuals

When a pandemic occurs, providing treatment to infected individuals is a critical reactive measure. The costs and effectiveness of this approach will depend on various factors, such as the severity of the pandemic and the resources available for treatment efforts.

Example tools that may be used to treat infected individuals include hospital beds, ventilators, oxygen therapy equipment, antiviral medications, and other medical equipment. These tools can be expensive to purchase and maintain, which can contribute to the overall cost of treating infected individuals during a pandemic.

The cost of treatment for infected individuals can vary depending on the severity of their illness and the type of care they require. For example, hospitalization and intensive care for severely ill patients can be very expensive, while providing supportive care to those with mild symptoms may be less costly.

Enhanced surveillance and monitoring

Enhanced surveillance and monitoring is a reactive approach that involves tracking the spread of a disease outbreak and identifying potential hotspots or clusters of infection. This approach can help authorities allocate resources, such as medical personnel and supplies, to areas where they are needed most, and take other actions to limit the spread of the disease.

To implement enhanced surveillance and monitoring, various tools and technologies can be used. For example, data analytics software can be used to analyze large volumes of data and identify patterns and trends in the spread of a disease outbreak. Medical databases can be used to track the number of cases, deaths, and recoveries from the disease, and to identify potential risk factors or other relevant information. Digital mapping tools can be used to visualize the spread of the disease outbreak and identify potential hotspots or clusters of infection.

The cost of implementing enhanced surveillance and monitoring will depend on a variety of factors, such as the scope and duration of the disease outbreak, the level of sophistication of the tools and technologies used, and the resources available for response efforts. For example, some data analytics software can be expensive to purchase and may require specialized training to use effectively. Similarly, creating and maintaining a medical database can require significant resources, including staffing and technology investments.

Social distancing and crowd control measures

Social distancing and crowd control measures are reactive approaches that can be used to limit the spread of a pandemic by reducing the number of people who come into close contact with each other.

Canceling large gatherings and events, closing schools and businesses, encouraging remote work, and promoting personal protective measures such as wearing masks and maintaining physical distance. Digital collaboration tools, teleconferencing software, mobile apps for symptom monitoring, contact tracing apps, and messaging platforms.

Limiting the number of people in public spaces such as parks and transportation systems, implementing one-way traffic flows, and controlling access to high-risk areas. Digital mapping tools, crowd monitoring software, and surveillance cameras.

The costs of implementing social distancing and crowd control measures can vary depending on the scale and duration of the pandemic and the specific measures being implemented. Some of the costs may include lost productivity due to remote work, decreased revenue for businesses, and expenses related to deploying and maintaining technology tools and communication channels.

Results of Proactive and Reactive Methods:

The effectiveness of proactive measures in pandemic management is evident from the experiences of different countries during the COVID-19 pandemic. Countries that took proactive measures early on, such as South Korea and Taiwan, were able to control the spread of the virus and keep the number of cases and deaths relatively low. In contrast, countries that were slow to respond or relied on reactive measures, such as the United States and Italy, saw much higher rates of infection and death.

A study published in the journal Health Affairs found that proactive measures such as contact tracing, isolation, and quarantine were effective in controlling the spread of the virus during the 2003 SARS outbreak in Taiwan. The study concluded that these measures prevented a widespread outbreak and reduced the number of cases and deaths.

Furthermore, a study by the National Bureau of Economic Research found that countries that invested more in public health infrastructure, such as disease surveillance and testing, had lower COVID-19 mortality rates. For example, countries with high testing rates, such as Germany and South Korea, had lower death rates than countries with lower testing rates, such as India, United States and Italy.

In software development, proactive approaches such as automated testing and continuous integration can result in more stable and reliable systems. A study by the National Institute of Standards and Technology (NIST) found that software defects introduced during the requirements and design phase were less expensive to fix than those introduced during the testing and maintenance phase.

Additionally, a study by IBM found that companies that invested in proactive software development approaches, such as automated testing and code reviews, had higher customer satisfaction and lower maintenance costs. The study concluded that proactive software development approaches resulted in more stable and reliable systems, which reduced the need for expensive maintenance and fixes.

The statistics show that proactive measures in pandemic management and software development can lead to more effective long-term success. Proactive measures such as contact tracing, vaccinations, and proactive software development approaches can help prevent future outbreaks, reduce maintenance costs, and improve customer satisfaction.

To summarize, reactive approaches in both fighting a pandemic and software development focus on identifying and addressing issues after they have occurred, while proactive approaches aim to prevent issues from occurring in the first place. Proactive approaches can be more expensive upfront but can save time and money in the long run, and are often more effective in achieving long-term success.

What can SQM and pandemic fighting learn from each other?

Pandemic fighting and software quality management both involve reactive and proactive approaches in risk assessment and continuous improvement. An infectious illness can evolve quickly so it is critical to continuously improve our methods of fighting a pandemic. The goal of software quality management (SQM) is to ensure high-quality which includes reducing downtime and any consequences of poor quality. SQM has more room for error and room for reactive approaches while pandemic fighting does not. It should employ more proactive approaches like the pandemic fighting efforts in the aforementioned countries that were able to contain the outbreak. At the same time, pandemic fighting needs to be able to implement more reactive approaches because proactive measures are not always available.

One of the main challenges of providing the public with a response to the COVID-19 pandemic was the rapidly evolving nature of the virus. As new information about the virus became available, decisions had to reflect it accordingly. SQM utilizes this technique in the Agile methodology. It can be used to quickly develop solutions for new emerging requirements. The ability to make high-quality decisions quickly would benefit mission critical systems which require time-sensitive responses. A company that can effectively implement Agile methods would improve time-to-market for software organizations.

The rate-limiting step in developing a specialized tool like a vaccine is the lab work. Before the introduction of the rapid-tests, initial tests required three days in order to incubate the virus for analysis. During this time, no data-driven decisions can be made. During this time, individuals should quarantine themselves to prevent spread and aid in the detection of its origin. SQM should similarly treat defects in their systems by isolating components. Ideally a system's components are decoupled from each other so that a single component can be modified without affecting the rest of the system. It is also much easier to debug if we can remove a suspected defective component from the system and perform a test on the rest of the system.

Pandemic fighting can implement SQM's automation techniques for identifying trends and defects. A goal of SQM is to predict changes in the future so that there is some level of preparedness for a sudden change. Like SQM, pandemic fighting involves collaboration between many different fields of life science. Some of these include public health, medicine, epidemiology, etc. Pandemic fighting can employ many of the same technologies as SQM, such as JIRA and Kanban boards. JIRA is a project management tool used to manage and track tasks as well as identify bottlenecks. Kanban boards are more visual and can be quickly updated to fit the needs of the situation.

Both pandemic fighting and SQM require continuous improvement efforts. There is more clarity in fighting a pandemic because the objective is to eliminate the spread or the impact of an infectious illness. When a vaccine is deployed and infections decrease, it is a clear indication that the solution is "good enough" and does not require further improvement. However at this point, the response effort should not be stopped. The illness needs to be monitored for mutations, resurgences, etc. The goal of SQM is to limit defects rather than eliminate them completely in order to reach acceptable customer satisfaction levels. Since customer demands are always changing, a "perfect" system today may not be "perfect" in the future. Therefore the software system will always need improvement.
