SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pandas, openpyxl, and includes scripts (resource) and references (resource) components.

What problem does it solve?

IT finance teams often struggle to explain why spend diverged from budget. This skill decomposes line-item variances into actionable TBM drivers and presents an auditable, multi-tier narrative.

Core Features & Use Cases

Tiered variance analysis by Cost Pool and Sub-Pool with primary driver attribution (VD.1–VD.11).
Generates a CFO-ready narrative, Tier 1–Tier 5 outputs, and an Excel workbook (plus optional interactive dashboard) to track and explain variances.
Validates data alignment to TBM v5.0.1 datasets (A1 output) and highlights data quality issues to prevent misattribution.
Use cases include identifying price/volume drivers in Cloud, Staffing, and Hardware; diagnosing new-item and cancelled spend; and producing audit-ready variance commentary.

Quick Start

Provide the A1-aligned dataset (budget, actual, Cost_Pool, Sub_Pool, etc.) and run the TBM Budget Variance Analyst to generate Tier 1–Tier 5 outputs.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I automate IT budget variance analysis using TBM driver codes?▼

IT budget variance analysis automation works by comparing Actual and Budget amounts at the line-item level, aggregating to Cost Pools, and attributing material variances to TBM driver codes to produce a CFO-ready narrative.

What is a TBM variance analysis framework and when do I need it?▼

A TBM variance analysis framework is a structured method to decompose IT spend divergences into actionable drivers like price and volume. You need it when explaining why Cloud, Staffing, or Hardware spend diverged from budget for leadership review.

How do I generate a CFO-ready variance report from actual and budget line-item data?▼

Generating a CFO-ready variance report requires providing an A1-aligned dataset with budget, actual, and Cost Pool columns. The analysis validates data alignment to TBM v5.0.1 rules and outputs a structured Excel workbook with Tier 1 through Tier 5 narratives.

Can I use pandas and openpyxl to export TBM variance outputs to Excel?▼

Yes, pandas and openpyxl are used to export TBM variance outputs to Excel. The process generates a downloadable workbook containing auditable variance commentary, driver attribution documentation, and confidence levels for leadership review.

What is the best way to diagnose price and volume drivers in IT cloud spend?▼

Diagnosing price and volume drivers in IT cloud spend is best handled by applying the Variance Analysis Framework to line-item budget and actual data. This approach attributes material variances to specific TBM driver codes and highlights any data quality issues preventing misattribution.

Why does my TBM variance attribution fail on misaligned cost pool data?▼

TBM variance attribution fails on misaligned cost pool data when the input dataset does not validate against TBM v5.0.1 A1 output rules. The analysis explicitly checks data alignment and highlights quality issues to prevent incorrect driver attribution.
