You must establish how your success will be measured, preferably on a regular basis and not right at the end.
|2.5 Define the Enterprise Data Platform|For example, start with this one from DatabaseAnswers.
3.0 Determine the StandardsThese can be Internal, External, National or International
|3.1 Easy where defined|
eg LGSL/IPSV, BVPIs
|3.2 Look for obvious Data Leaders|
eg Social Services for Ethnic Origins
|3.3 Create a Glossary for Data Mapping|
You need a Glossary from early on.
It provides a structure, signs of progress and helps people feel involved.
|3.4 Aim for Buy-In|
It's difficult but very important to get buy-in early on.
Remember this is a business Project, not a technical one.
4.0 Perform a Data Quality AuditDesign the Infrastructure

Especially to management

Boring but essential.
You must look at your Project thru the eyes of the Sponsors.
|4.3 Carry out Enterprise-wide DQ Audit|
Tools and Techniques are Enterprise-wide
|4.4 Data Profiles suggest Standards|
A simple example is an analysis of Genders.
We might expect to get many examples of M/F and a few 0/1's so we would choose M/F.
|4.5 Obtain Buy-In from Data Stewards|
It's good to find people who will take ownership of different kinds of data.
They then feel committed to making things work.
This reduces your workload and increases your chances of success.
If you don't get buy-in, your job is going to be very difficult.
5.0 Define the Scope
This is where we establish the 'Things of Interest' that are in Scope.
|5.1 Reference Data|
For example, Payment Methods.
Probably the single most important 'Thing of Interest'.
