The ATOM Model Explained
Concept and Origin
The ATOM Model was developed in response to the growing complexity and necessity of test automation in software development. Recognizing the challenges organizations face in assessing and improving their test automation strategies, the ATOM Model offers a structured, systematic approach.
At Automate The Planet, we’ve spent years perfecting the ATOM Model, significantly improving test automation for a wide range of organizations, from dynamic startups to major Fortune 500 companies. Our approach is thorough: we don’t just craft an initial action plan, we also form a dedicated team of skilled Automate The Planet engineers. This team works closely with organizations to bring these plans to fruition. While each plan is customized to suit the specific needs of each organization, our track record is a testament to the model’s effectiveness. To date, we’ve achieved a 90% success rate with the ATOM Model. It’s essential to be realistic – I steer clear of claiming a perfect success rate because there are always unpredictable factors, such as global events like COVID-19, economic downturns, or stock market changes. These can influence an organization’s budget and staffing, along with internal factors like acquisitions and office politics. However, putting these external elements aside, I am confident that, technically, the ATOM model plans are solid and lead to successful outcomes.

Calculating the Test Automation Excellence Index (TAEI): A Detailed Approach
The goal here is to quantitatively assess the maturity of an organization’s test automation capabilities. To calculate the Test Automation Excellence Index (TAEI), we consider three key dimensions: the Team Skill Index (TSI), the Test Quality Index (TQI), and Automated Testing Coverage (ATC). Each of these dimensions is scored on a scale from 0 to 10. The formula for Test Automation Excellence Index TAEI is:
TAEI = (TSI + TQI + ATC)/3
Calculating the Test Quality Index (TQI)
The Test Quality Index (TQI) evaluates the robustness and reliability of the automated tests themselves. Key factors in calculating the TQI might include:
- Tests Relevance: Involves a thorough assessment of how closely the automated test cases align with essential business workflows and technical specifics of the application under test.
- Test Reliability: Determining the stability of the tests, i.e., how often they pass without false positives or negatives.
- Best Practices: Evaluating the adherence to test design principles and automation best practices, such as using clean code, proper test data management, and avoiding hard-coded values.
- Maintenance Effort: Considering how much time and effort are required to maintain the test suite, including updating tests for new features or fixing broken tests due to application changes.
Our strategy involves conducting thorough research and assessments of different tools, frameworks, and technologies to improve the test automation workflow. Predominantly, we rely on our in-house developed system at Automate The Planet, known as the ‘Assessment System for Evaluating Test Automation Solutions’, for these evaluations.
Calculating Team Skill Index (TSI)
TSI assesses the overall competence and proficiency of the test automation team. This is determined by evaluating the team’s expertise in relevant programming languages, familiarity with automation frameworks, and understanding of best practices in test automation. You might consider factors like certifications, years of experience in test automation, and performance in technical assessments or coding challenges. You can check the following article for such questions. Alternatively, you can use a service such as HackerRank.
Calculating Automated Testing Coverage (ATC)
ATC can be challenging to gauge, as it depends on whether your tests are based on manual test cases or not. While some organizations measure pure code coverage post-test execution, this can be misleading as it often excludes logic in databases or front-end components. In distributed cloud architectures or systems with many microservices, accurately determining coverage becomes even more complex. A more effective method might be to compile a comprehensive list of all major business areas, subareas, and workflows, and then evaluate whether they are adequately covered by automated tests. This approach is tailored and requires a nuanced understanding of each organization’s specific context.
The Test Automation Excellence Index offers a numeric representation of an organization’s test automation maturity, providing an objective basis for improvement plans.
Examples
A TAEI of 25-30 indicates excellent test automation maturity, with each dimension scoring above 5 points.
-
Example with TSI = 7, TQI = 7, ATC = 5:
-
TAEI = (7 + 7 + 5)/3 = 19/3 ≈ 6.33
-
This suggests a robust test automation setup but indicates a need for additional workforce to further enhance test automation coverage and quality.
-
Example with TSI = 3, TQI = 7, ATC = 8:
-
TAEI = (3 + 7 + 8)/3 = 18/3 = 6
-
This might reflect a recent transition from manual to automated testing, indicating a high quantity but lower quality of tests. It calls for team training and possibly external expertise.
-
Example with TSI = 8, TQI = 8, ATC = 8:
-
TAEI = (8 + 8 + 8)/3 = 24/3 = 8
-
This represents a very high level of test automation maturity, suggesting only minor adjustments or additional staff might be needed.
-
Example with TSI = 6, TQI = 5, ATC = 4:
-
TAEI = (6 + 5 + 4)/3 = 15/3 = 5
-
A score of 5 indicates a moderate level of maturity. This scenario might require a focus on enhancing test design and expanding coverage areas.
-
Example with TSI = 3, TQI = 3, ATC = 3:
-
TAEI = (3 + 3 + 3)/3 = 9/3 = 3
-
A TAEI of 3 reflects a nascent stage of test automation maturity. It points to the need for significant improvements across all areas.
-
Example with TSI = 4, TQI = 8, ATC = 3:
-
TAEI = (4 + 8 + 3)/3 = 15/3 = 5
-
This score suggests high test quality but gaps in team expertise and test coverage. Strategic hiring and focused efforts to expand automated testing are recommended.
By examining these examples, you can draw similar conclusions in different scenarios. This calculation is just one aspect of the ATOM Model, providing vital insights into the next steps for enhancing test automation.
