Here is a list of the things we do in our validation steps at Humana. Keep in mind we have cost transparency, applications and services and Business Units.
We do a month over month comparison of totals in various layers, including costs within each object with the 'layers' so we can identify any anomalies in the totals and provide explanation if needed.
Aggregate totals of Cost Source to Towers & Subtowers (and all objects totals between)
- Validate all objects totals for month over month trending and identification of anomalies
- Detailed validations of Towers & Subtowers for month over month trending and identification of anomalies
Applicaiton TCO totals
- Application TCO Cost Drivers totals for month over month trending and identification of anomalies
Services to Business Units
- Services totals for month over month trending and identification of anomalies
- Business Unit totals (for month over month trending) and identification of anomalies by service
Unit Metrics
- Tower & Subtower Units and Unit costs for month over month trending and identification of anomalies
We use an Excel spreadsheet for our validation (but we use many of the reports available in Apptio for this monthly validation). Our hope is that we can create something similar in Apptio at some point so it will automatically update and we'll just have to review the reports for anomalies. If you would like a copy of our Excel file, just email me and I'll be glad to send along our template.
