11. IFRS

IFRS (International Financial Reporting Standards) is the global framework many countries use to prepare financial statements, ensuring cross-border comparability.

Why It's Important

If your company operates internationally or reports under multiple frameworks, IFRS literacy keeps cost accounting consistent across borders.

How to Improve IFRS Skills

1. Keep current: Track IASB updates, transition guidance, and agenda decisions; summarize impacts for your team.

12. SQL

SQL (Structured Query Language) retrieves and shapes data from databases—vital when your costs live across ERP tables, data warehouses, and logs.

Why It's Important

It lets you pull large datasets fast, join them cleanly, and build repeatable analyses for costing, budgets, and forecasts.

How to Improve SQL Skills

1. Core commands: Get fluent with SELECT, INSERT, UPDATE, DELETE, and filtering with WHERE.

2. Aggregation: Use GROUP BY with SUM(), AVG(), COUNT(), and conditional logic to build cost rollups.

3. Joins: Master inner, left, right, and full joins to stitch fact and dimension tables reliably.

4. Subqueries and CTEs: Structure complex logic for clarity and reuse; layer steps without losing readability.

5. Performance: Read execution plans, add indexes prudently, and avoid unnecessary scans.

6. Practice: Solve real problems from your environment; recreate KPI queries and reconcile to the books.

7. Stay current: Learn dialect features (T-SQL, PL/SQL, PostgreSQL) and window functions for advanced analytics.

8. Apply to cost work: Build BOM explosions, inventory aging, standard vs. actual cost bridges, and margin waterfalls.

SQL turns scattered data into one clean narrative. That’s power.
