Key causes of failures

  • No good state of the end goal of a project. The desired outcome that is hoped to be achieved by completing the project. 
  • Poor-quality data can lead to wrong conclusions and unreliable results due to lack of research, not properly assessing the data available.
  • Lack of communication. Data science projects are complex and require collaboration between data scientists, engineers, and stakeholders. Results can lead to misunderstandings and incorrect assumptions being made. 
  • Poor Modeling: If the wrong model is chosen or the model is not fine-tuned properly, the project may not yield the desired results. 

How cognitive task analysis can ensure success of data sciences projects

  • Identify what the problem project is intended to solve and create a measurable objective that will be used to assess success. Ensure that everyone is on the same page and understands what is expected of them. Cognitive task examines how users interact with a system and the underlying cognitive processes that drive their behavior. It helps to identify and address potential problems or areas of improvement, as well as provide insights into how users may use and interact with the system in the future. By studying user behavior and understanding their mental processes, it allows them to identify the specific goals of a project and develop appropriate strategies to achieve them. It identifies desired outcomes, uncover user needs and expectations, and develop user-centered design solutions. 


  • Cognitive task analysis used to capture the right data source for AI projects by helping to identify the data needs. By identifying the specific mental processes and strategies used by participants in completing a task help to identify data sources. Additionally, cognitive task analysis can help to identify potential areas of improvement in the AI project, such as changes to data collection or the user interface.


  • By understanding the cognitive processes involved in data science projects, teams can better communicate with each other, increase efficiency and improve the overall quality of their work. For example, a cognitive task analysis can help the team identify the steps and interactions necessary for the successful completion of a project, as well as the resources and expertise that are needed to achieve the desired results. Additionally, it can provide insight into how to best communicate with each other, as well as how to engage stakeholders and make the best use of available resources. 


  • Cognitive task analysis (CTA) identify the cognitive processes used by people when completing a task. By understanding the thought processes, interactions, and decisions that people make when completing a task, data scientists can identify the underlying cognitive processes that can be used to improve their models. Using CTA, data scientists can identify the logic, preferences, and problem-solving processes that are used when completing a task. This information can then be used to create better models that take into account the cognitive processes and help to improve the accuracy and reliability of the model. Additionally, CTA can help to identify any potential errors or biases in the data that could lead to inaccurate models. By understanding the underlying cognitive processes, data scientists can create more realistic models that are better suited to the task at hand. Finally, CTA can also be used to help determine the most effective strategies for collecting data and developing algorithms that are tailored to the specific needs of the project. By understanding the cognitive processes involved in the task, data scientists can focus on the data that is most relevant to the task and develop the most efficient algorithms for achieving the desired results.
