How do I see cost variance across my portfolio?
Bildstak's portfolio module federates cost and schedule data from every connected project, then ranks them by cost variance, spend-to-date, EAC and claim exposure — so portfolio directors see which projects need intervention without waiting for monthly reports.
Seeing cost variance across a portfolio is harder than it sounds: each project may use a different ERP, a different cost-code structure, and report on a different cycle. The usual result is a portfolio summary built from emailed spreadsheets, days after month-end.
Bildstak connects to your project cost sources (SAP, Maconomy, spreadsheets, or any connected system) across the portfolio and normalises the data into a single model:
1. Connect each project's cost source — one connection per project, or a single ERP with multiple cost centres. 2. Set your baselines — approved budgets and contract values per project, used to calculate variance. 3. Query the portfolio — ask "which of my projects are over budget?" or "rank projects by cost performance index" and Bildstak returns a cited table. 4. Drill in — click any project to see the breakdown by package or WBS node, or ask a follow-up question about the biggest variance items.
Portfolio metrics Bildstak surfaces:
- Budget vs. actual spend and forecast at completion
- Cost variance (CV) and cost performance index (CPI)
- Claim and variation exposure by project
- Supplier or subcontractor cost concentration risk
Because every metric cites its source record, the output is audit-ready rather than an aggregated number with no provenance. Portfolio directors often use this alongside the Analyst module, which autonomously investigates which projects carry the most risk and surfaces evidence across all connected sources.
