CHENNAI: With an aim to provide good governance and improve access and quality of services offered to the people, the State government on Wednesday unveiled a new Tamil Nadu Data Policy. The key objective of the policy is to develop data capabilities covering all aspects of governance, including policy making, administration, reviewing schemes, and redesigning policies to develop data driven decision-making, a Government Order said. 

Tamil Nadu e-Governance Agency (TNeGA), which will function as the repository for all data, will help departments in analysing data and drafting policies. The new policy will minimise exclusion and inclusion errors in government schemes and promote data analytics capabilities of departments. A State-level empowered data governance committee headed by chief secretary will provide strategic guidance for the State data policy framework, while a data inter-departmental committee headed by chief executive officer of TN e-governance agency, who will be the State’s chief data officer, will take operational-level decisions emanating from the policy.

Similarly, a department data officer in each department shall be responsible for collating data in the department, decisions relating to open data, storage compliance, and implementing decisions of the data interdepartmental committee.

“A data-driven, decision making culture is key to deliver efficacious governance for larger public good. By driving data integrity, governments can foster innovation, effectiveness and efficiency across all departments and schemes, and deliver higher levels of impact, inclusion and transparency. It’s heartening to note that the TN government has brought in experts from the academia and NGOs to contribute to policy making,” said Ramkumar Ramamoorthy, Pro Vice-Chancellor, Krea University, and former chairman and managing director, Cognizant India.

A comprehensive and mandatory Meta Data Catalogue for all departments will be prepared and updated from time to time which contains the definition of each of the citizen-centric fields and master data, including the source of truth and responsible departments or data fiduciary.
