                                           iii.         Scalability

                                           iv.         Securityat the OT / IT boundary

• Act as the final technical authority for data architecture and design decisions.

3.     Analytics Architecture &Enablement

• Transform curated OT data into analytics-ready fact and dimension models.
• Design and maintain data marts and datasets for dashboards and reporting.
• Define and govern the analytics and semantic layer, enabling consistent KPI usage.
• Establish standards for:

                                              i.         Metriccalculation logic

                                             ii.         Grain,time windows, and aggregation rules

• Ensure a single source of truth for business metrics and prevent metric duplication.
• Enable self-service analytics for data analysts through well-documented, trusted data sets.

4.     Data Governance, Quality &Lineage (Embedded)

• Implement data governance embedded into pipelines and analytics models, including:

                                              i.         Dataownership and domain attribution

                                             ii.         Technicalmetadata capture (tags, units, frequency, source)

• Define and enforce data quality rules (completeness, validity, timeliness).
• Ensure end-to-end lineage and traceability from OT source systems to business KPIs.
• Apply access controls and data security policies aligned with OT and enterprise standards
• Maintain documentation to support auditability, explain ability, and trust
• Work closely with data analysts and stakeholders to ensure data is fit-for-purpose.

5.     Collaboration & Enablement

• Partner with data analysts to translate business requirements into scalable analytics solutions.
• Validate analytics outputs against business intent and operational reality.
• Act as a technical advisor to stakeholders on data usage, limitations, and interpretation.
• Drive continuous improvement of the data platform and analytics ecosystem.
