Data/AI Flashcards
How do you support data quality?
- Define data quality standards e.g. standers for accurate policyholder info, names, addresses, contact detail, etc
- Conduct data quality assessment e.g. involew3 analyzing data to ensure its accurate, complete, up-to-date
- Establish data governance e.g. ensure compliance with regulations and mating customer trust. Involve defining roles and responsibilities for data management, establish policies for data access and use, implement procedures for data quality assurance
- Implement data quality controls: involve implementing data validation checks at various data flow points
- Training on best practices, standards, policies and procedures and monitoring (regulars data quality audits)
Question: Can you explain the importance of data governance in an organization?
Data governance is crucial because it ensures data quality, compliance with regulations, and effective data management. It establishes policies, processes, and standards for data handling, which not only enhances data accuracy but also builds trust among stakeholders. Moreover, it helps organizations make informed decisions, optimize operations, and mitigate risks associated with data misuse or breaches.
How do you establish a data governance framework in an organization that has never implemented one before?
Answer: To establish a data governance framework, I would follow these steps:
- Assessment: Begin with a thorough assessment of the organization’s current data landscape, including data sources, systems, and data flows.
- Stakeholder Engagement: Engage key stakeholders to define data governance objectives, responsibilities, and goals.
- Policies and Standards: Develop data governance policies, standards, and guidelines, aligning them with industry best practices and regulatory requirements.
- Data Ownership: Assign data stewards and owners for different data domains or assets to ensure accountability.
- Data Quality Framework: Implement data quality measures, monitoring, and reporting mechanisms.
- Education and Training: Provide training to staff on data governance principles and practices.
- Continuous Improvement: Establish a governance council to oversee ongoing governance activities, assess effectiveness, and make necessary improvements.
3. Question: How would you handle a situation where there’s resistance from business units or departments to comply with data governance policies and procedures?
Answer: Addressing resistance to data governance requires a collaborative approach: - Communication: Engage in open and transparent communication to explain the benefits of data governance, such as improved data quality and decision-making.
- Alignment: Ensure that data governance policies align with business objectives and processes, and adjust them if needed.
- Education: Provide training and support to business units to help them understand and implement data governance practices.
- Demonstration of Value: Showcase success stories and tangible benefits resulting from data governance implementation.
Feedback Loop: Encourage feedback and suggestions from business units to make data governance more practical and effective.

2. Setting definitive project objectives - basically what do I need to achieve and when?
3. Ascertain project deliverables - how are we going to get to where we need to be by utilizing which resources? Every data science project’s requires different set of resources
4. Create schedule
5. Conduct project risk assessment - what are foreseeable issues and how to mitigate
6. Present plan to stakeholders and obtain buy-in
Walk me through an example data pipeline design and sequence of activities in azure.
Here’s an example of a data pipeline design and sequence of activities using Azure:
1. Data collection: Collect data from various sources, such as internal data and third-party data sources. The data should include crash event data and contextual data (e.g. road conditions, weather, traffic). Store the data in Azure Data Lake Storage or Azure Blob Storage.
2. Data preparation: Use Azure Databricks or Azure HDInsight to clean, transform, and normalize the collected data. This process involves handling missing values, removing outliers, and converting data into a format suitable for analysis.
3. Data partitioning: Partition the prepared data into training, validation, and test datasets. Store the partitioned data in Azure Data Lake Storage or Azure Blob Storage.
4. Algorithm selection: Select an appropriate algorithm for the crash detection task, such as a machine learning algorithm, deep learning algorithm, or a computer vision algorithm.
5. Feature engineering: this could be highly iterative process. some steps include: experimenting with hyperparameters and configuration, data preposssing (e.g. removing or normalization certain elements such as special characters, html tags, punctuations), labeling, tokenization, and more)
6. & Algorithm training: Train the selected algorithm using Azure Machine Learning or Azure Databricks. Evaluate the performance of the algorithm using the validation data and make any necessary adjustments to improve its performance.
7. Algorithm testing: Test the algorithm on the test data to evaluate its performance. The test data should be independent of the training and validation data.
8. Deployment: Deploy the trained algorithm as a web service using Azure Container Instances or Azure Kubernetes Service.
9. Monitoring and maintenance: Continuously monitor the solution and make improvements as needed. Use Azure Monitor to track the performance and availability of the deployed algorithm.
Note: The choice of Azure services will depend on the specific requirements and goals for the solution. These steps can be adjusted as needed to meet the specific needs of the client.

Can you explain your understanding of AI and its potential impact on our organization’s goals?
“AI, or artificial intelligence, refers to the simulation of human intelligence processes by machines, particularly computer systems. It involves the development of algorithms and models that enable computers to perform tasks that typically require human intelligence, such as decision-making, problem-solving, and learning from data. In the context of our organization, AI can drive various benefits, such as optimizing processes, enhancing customer experiences, and enabling data-driven decision-making for more strategic outcomes.”
How would you assess our organization’s readiness for AI adoption?
Assessing AI readiness involves evaluating both technological and organizational aspects. I would start by understanding our current data infrastructure, the quality and availability of data, and our existing technology stack. Additionally, I’d assess the organization’s AI knowledge and skills, as well as the cultural openness to embrace AI-driven change. A comprehensive readiness assessment would help us identify strengths, gaps, and potential roadblocks in our AI adoption journey.”
How do you envision aligning AI strategy with overall business objectives?
Aligning AI strategy with business objectives is crucial for successful implementation. I would start by engaging with business leaders to understand their goals and pain points. Then, I’d identify opportunities where AI can provide solutions or enhancements. By demonstrating how AI can directly contribute to achieving specific business KPIs, we can build a strategic roadmap that prioritizes initiatives with the highest potential for impact.”
Could you describe a situation where you successfully translated technical AI concepts to non-technical stakeholders?
“Certainly. In my previous role, we were implementing a machine learning solution to enhance customer support. To convey its value to non-technical stakeholders, I focused on the end benefits rather than the technical details. I used relatable analogies to explain how the AI model would analyze customer interactions to predict and resolve issues more efficiently. This approach helped bridge the gap between technical complexity and business objectives, resulting in support from both sides.
How do you plan to address the ethical considerations and potential biases associated with AI implementations?
“Ethical considerations and biases are critical aspects of AI strategy. I believe in adopting a proactive approach by establishing clear ethical guidelines for AI development and deployment. This involves forming a cross-functional team that includes both business and technical perspectives. Regular audits of AI models for biases and a commitment to transparency in our AI decision-making processes are also essential components to ensure ethical and responsible AI usage.”
