A field-tested analysis method to identify approval bottlenecks in construction ERP and cut approval cycle time by redesigning workflows.
Problem pattern in Bau projects
Most approval delays are not caused by system performance. They are caused by hidden handoffs between site, procurement, finance, and subcontractor controls.

Where delays accumulate
- Missing cost code metadata on site requests
- Email-based exception handling outside ERP
- Duplicate manual checks for thresholds already encoded in policy
Instrumentation metrics
- median_hours_by_stage
- rework_count_before_approval
- request_age_distribution
- approval_sla_breach_ratio
Redesign principles
- auto-route by project type and spend threshold
- enforce required metadata before submission
- collapse duplicate approvals into a single policy engine
