Why
The allocation model is worthless if nobody sees the output. Regular showback creates the accountability loop that drives cost-conscious behaviour. When budget owners receive their cost report monthly, acknowledge receipt, and review trends, they start asking “why did this go up?” — and that question is the beginning of optimisation. Without showback, costs are invisible and nobody feels responsible.
What
Establish a regular showback process where cost reports are delivered to budget owners at least monthly. Reports show allocated costs by application, environment, and team with month-on-month trends. Budget owners acknowledge receipt and review.
How
Define the Showback Report Template
Each budget owner should receive a report containing:
| Section | Content |
|---|---|
| Summary | Total allocated cost this month, % change vs prior |
| By Application | Top applications by cost, with trend arrows |
| By Environment | Prod vs non-prod split (non-prod waste indicator) |
| Anomalies | Any cost spikes flagged during the month |
| Optimisation Opportunities | Open recommendations assigned to this team |
| Shared Cost Allocation | What shared costs were attributed and the method |
Choose Delivery Method
| Method | Best For | How |
|---|---|---|
| Dashboard access + email | Self-service organisations | Scheduled email with dashboard link |
| PDF report via email | Executives who won’t open dashboards | Scheduled export from BI tool |
| Meeting-based walkthrough | Early maturity, building the habit | Monthly 30-min slot per BU |
Recommended: start with meeting-based for the first 2–3 months to establish the habit, then transition to self-service dashboards with emailed summaries.
Build Delivery Automation
| Provider | Automation |
|---|---|
| AWS | QuickSight scheduled email with embedded dashboard |
| Azure | Power BI subscription (scheduled email with report) |
| GCP | Looker Studio scheduled delivery, or BigQuery → email via Cloud Functions |
| Cross-cloud | Grafana report scheduling, or custom pipeline |
Establish Review Cadence
| Cadence | Activity |
|---|---|
| Monthly | Cost report delivered. Budget owner acknowledges receipt. 15-minute review meeting for top-3 cost changes. |
| Quarterly | Full showback review with Finance. Validate allocation accuracy. Adjust shared cost rules if needed. |
Track acknowledgement: if a budget owner hasn’t opened/acknowledged the report within 5 business days, escalate to their manager. The report only drives behaviour if it’s actually read.
