• Performance Metrics: Defining success criteria and key performance indicators (KPIs) for ML models.
• Evaluation: Evaluating the business impact and effectiveness of ML models.

6. Project Managers

Project managers oversee the end-to-end lifecycle of ML projects, ensuring they are delivered on time and within scope. Their key activities include:

• Planning: Creating project plans, timelines, and resource allocations for ML projects.
• Coordination: Coordinating with cross-functional teams, including data scientists, ML engineers, and stakeholders.
• Risk Management: Identifying and mitigating risks that may impact project success.
• Reporting: Providing regular updates and progress reports to stakeholders and executives.

7. UX/UI Designers

User experience (UX) and user interface (UI) designers focus on creating intuitive and user-friendly interfaces for ML-powered applications. Their responsibilities include:

• Design: Designing interfaces that provide a seamless and engaging user experience.
• Prototyping: Creating prototypes and wireframes to visualize the user interface.
• Usability Testing: Conducting usability tests to gather feedback and make design improvements.
• Collaboration: Working with developers to ensure that the final product aligns with design specifications.

8. Compliance and Ethics Officers

Compliance and ethics officers ensure that ML models adhere to legal, regulatory, and ethical standards. Their key activities include:

• Regulatory Compliance: Ensuring that ML models comply with relevant laws and regulations.
• Ethical Considerations: Addressing ethical issues related to bias, fairness, and transparency in ML models.
• Data Privacy: Implementing measures to protect user data and ensure data privacy.
• Audit and Review: Conducting audits and reviews to ensure ongoing compliance with ethical guidelines.

9. Domain Experts

Domain experts possess specialized knowledge in specific industries or fields, such as healthcare, finance, or retail. Their responsibilities include:

• Expertise: Providing domain-specific knowledge and insights to guide ML model design.
• Validation: Validating the relevance and accuracy of ML models in the context of the domain.
• Collaboration: Collaborating with data scientists and ML engineers to ensure that models address domain-specific challenges and opportunities.

10. Stakeholders and Executives

Stakeholders and executives provide strategic direction and decision-making support for ML initiatives. Their key activities include:

• Strategic Alignment: Aligning ML projects with organizational goals and objectives.
• Decision-Making: Making informed decisions about resource allocation and project priorities.
• Support: Providing support and guidance to ensure the success of ML projects.
• Evaluation: Evaluating the overall impact and return on investment (ROI) of ML initiatives.

Conclusion
