From multi-day reporting cycles to hours at NAB.

The challenge.

In a bank the size of NAB, risk and regulatory reporting draws on many systems — core banking, lending, treasury, markets and finance ledgers among them. Each carried its own definitions of a customer, an exposure and a product, and each cycle a small army of analysts exported, reconciled and stitched the numbers together by hand. The result was a reporting process that ran for several days, absorbed senior time and left too much room for a mismatched definition or a stale extract to slip through.

The deeper issue was governance, not tooling. Without agreed ownership, common definitions and traceable lineage, no report could be trusted without a manual check — and no automation could safely be built on shifting foundations.

What RUBIX did.

RUBIX started with the governance layer, then automated on top of it. Working alongside the bank's risk, finance and data teams, we:

• Established a data governance framework — data ownership, stewardship, a business glossary of agreed definitions, and quality rules mapped to the metrics that regulators and the board actually rely on.
• Documented end-to-end lineage from source systems through transformation to each reported figure, so every number could be traced and defended.
• Consolidated more than a dozen source feeds into a single governed reporting layer — one place where a given measure is defined once and calculated once.
• Automated the risk and regulatory reporting pipeline, replacing manual collation with scheduled, access-controlled and logged runs, with exceptions surfaced for review rather than hunted for.

Throughout, delivery stayed fixed-scope and vendor-independent — no bloated team, no open-ended engagement, and controls that fit the bank's existing risk and change processes.

The results.

With definitions agreed and the pipeline automated, the reporting cycle that once took several days now completes in hours. Analysts spend their time reviewing exceptions and explaining movements rather than assembling spreadsheets, and leaders work from one set of numbers instead of reconciling competing versions.

• Reporting cycle reduced from days to hours for priority risk and regulatory reports.
• One source of truth across 12+ systems, with a single agreed definition for each key measure.
• The large majority of manual collation steps automated, with full lineage and audit logging.
• Faster, more defensible responses to regulator and board queries.

Representative example — figures illustrate the type of outcome RUBIX delivers for organisations of this kind and are not a precise account of a specific engagement.

Why it matters.

Regulatory reporting fails when the data underneath it is ungoverned — and no amount of automation fixes an ownership problem. RUBIX's data governance consulting puts the ownership, definitions and lineage in place first, so automated reporting is fast, auditable and trusted. For regulated organisations, that combination turns reporting from a recurring scramble into a controlled, repeatable process.
