• Tools are only a part of the solution

• Good formula : People + Processes + Tools– « Data governance is between 80 and 95%

communication » - Dec 2006 Data Governance Conference

• We have the tools, let’s talk about the rest…

If all you have is hammer…

THE DATA STEWARD


• Wikipedia: Stewardship is an ethic that

embodies the responsible planning and

management of resources.

CONCLUSION


• Tools are nothing without people and

processes

• Governance is different in every company– Decided and sponsored by the executives, inscribed in

a global strategy

– Adapted to your organization

– The Data Steward as the local implementation of it

A matter of governance


1. Build an Information Management Platform

2. Identify your processes & Org Chart

3. Write the Data Steward « Job Profile »

4. Identify the right people for the job

5. Leverage Self-Service BI

• Ask your local experts

How to start tomorrow ?


• A Data Culture– See Satya Nadella

April 15th 2015 presentation in SF

• To at last step up in the

knowledge pyramid!– Machine learning \o/

All this for what?


Any questions ?

Thank You !
