How confident are you in well allocation

figures?

Confident or Very Confident 45%

Unconfident or Very Unconfident 55%

Data Maturity

Production Data

Maturity Chart

Non-existentOrganization has no data governance approach, does not understand the need for governance and has no stewardship functions.

Ad hoc

Organization performs occasional, non-standardized stewardship activities but has no formal data governance approach.

Standardized

Organization has implemented some standard data governance practices and has standardized the stewardship role.

Committed

Organization has instituted formal data governance for all business units and has dedicated stewards for all business units.

Consolidated

Data governance and stewardship are coordinated across the enterprise, involving business and information technology and management in partnership.

Data is in

excel hell

What’s wrong with spreadsheets?

Manual data entry error

Broken links to other sheets

Not stored centrally – c drive common

Poor collaboration

Non QC’d algorithms

Version Control non existent

Poor security

No compliance with regulator

Excel – the Return

Let in the Light

• Scale change time saving for

engineering processes

• Seconds to run reports, not hours.

• Improved Allocation consistency

between HAC and PE's

• New workflows now
