APS BUYER GUIDE
Advanced Planning & Scheduling Software Procurement Guide
A standards-aware procurement guide for finite-capacity scheduling and advanced planning systems in manufacturing.
Technical scope to define
- Planning horizon, finite-capacity constraints, sequence-dependent changeovers, labor/tool constraints and campaign rules.
- ERP/MRP, MES, historian and master-data interfaces, including ownership of routings, calendars and work-center capacity.
- Replanning triggers, frozen zones, manual overrides, explanation of optimizer decisions and schedule-release governance.
Evidence to request
- A representative proof of concept using real routings, constraints and production data rather than a generic demo.
- Schedule-quality metrics such as on-time delivery, WIP, changeover time, utilization and schedule stability before and after optimization.
- Interface specification, data ownership, recovery behavior, security architecture and auditability of manual changes.
Commercial normalization
- Separate implementation, integration, data cleansing, training and recurring subscription/support costs.
- Define acceptance criteria before implementation and tie them to an agreed baseline and measurement period.
- Confirm exit/export rights for master data, schedules, custom rules and configuration.
