SAP Product Lifecycle Costing: Powering the Next Generation of Cost Management
In an era defined by electrification, raw material volatility, and geopolitical uncertainty, cost planning has once again become a core management priority.
In this series, we explore how companies can elevate cost planning by leveraging SAP—aligned with the product lifecycle.
As the first installment, this article focuses on:
- The Idea / Concept Phase
- The Design / Development Phase
and explains how SAP enables advanced, data-driven cost management at each stage.
Why Cost Planning with SAP Matters More Than Ever
Cost planning is not merely about cost control.
Its true essence lies in:
Designing a profit-generating cost structure in the upstream phase,
analyzing actual performance after mass production,
and continuously feeding insights back into development.
This closed-loop cost management model is the foundation of modern cost planning.
However, in many organizations, information remains fragmented:
- Design: BOM managed in Excel
- Procurement: Quotations handled separately
- Manufacturing: Process-based systems
- Finance: Standalone accounting systems
As a result, end-to-end visibility is limited.
SAP’s greatest strength is its ability to integrate these functions into a unified data model.
By connecting design, procurement, manufacturing, finance, and sales, SAP enables a seamless cycle:
Simulation → Agreement → Execution → Performance Analysis → Feedback
This transforms cost management from fragmented control into a strategic management discipline.
Product Lifecycle and Cost Planning Framework
This series follows the product lifecycle of Tier-1 automotive suppliers:
- Idea / Concept
- Design / Development
- Industrialization / Pre-Production
- Production
- Service / End-of-Life
This article covers Phases 1 and 2.
1. Idea / Concept Phase
Overview
In this phase, companies develop new product concepts based on OEM requirements and market trends, and define:
- Target profit margins
- Target costs
At this stage, neither design nor BOM is finalized.
Therefore, cost estimation is based on:
- Similar products and historical data
- Functional and performance requirements
- Modular structure assumptions
- Weight and material models
- Market price reverse calculations
Objectives
- Establish: Target Price − Target Profit = Allowable Cost
- Evaluate profitability by vehicle and program
- Visualize new cost structures related to EVs, batteries, and semiconductors
How SAP Supports This Phase
1. SAP Product Lifecycle Costing (PLC)
With PLC, companies can build rough cost models at the concept level and conduct early-stage simulations, including:
- Concept A/B comparisons
- Material substitution scenarios
- Make-or-buy analysis
- Future volume simulations
These analyses can be performed quickly and systematically.
2. Profitability Simulation (CO-PA / SAC)
Using SAP Analytics Cloud and Margin Analysis, companies can visualize:
- Program-level profitability
- Profit forecasts by vehicle, region, and customer
- What-if scenarios for exchange rates and material prices
Value for Tier-1 Suppliers and OEMs
For Tier-1 Suppliers
- Improved RFQ accuracy
- Shorter quotation lead times
- More reliable bid decisions
For OEMs
- Higher accuracy of cost targets
- Early detection of unprofitable programs
- Profit management from the early development stage
2. Design / Development Phase
Overview
In this phase, RFQs, drawings, and specifications are finalized, and close collaboration begins among:
- Engineering
- Procurement
- Manufacturing Engineering
Most of the product’s cost structure is determined here.
Decisions made in this phase largely define long-term profitability.
Objectives
- Build-up costing based on BOM × Process × Procurement Price
- Immediate assessment of design change impacts
- Identification of VE/VA opportunities
How SAP Supports This Phase
1. Detailed Cost Modeling (PLC)
SAP enables scenario comparisons by:
- Design alternatives
- Materials
- Production locations
- Suppliers
at the RFQ and program levels.
2. Design Change and Cost History Management
Through CAD/PLM integration, SAP tracks:
- Which ECN caused changes
- How much cost was affected
This ensures transparency and smooth cross-functional coordination.
3. Real-Time Procurement Price Integration
Supplier quotations and contract prices are registered in PLC, enabling real-time analysis of cost drivers.
4. Standard Cost Planning (Product Cost Planning)
With integrated Engineering BOM and Manufacturing BOM, SAP supports:
- Multi-level BOM costing
- Make-or-buy consolidation
- Precise standard cost calculation
Target vs. Actual Cost Analysis
SAP enables comprehensive analysis, including:
- Visualization of target vs. actual gaps
- VE cost-reduction tracking
- Design change impact tracing
- Version-based comparisons
These insights directly support executive decision-making.
Value for Tier-1 Suppliers and OEMs
For Tier-1 Suppliers
The greatest benefit is:
Preventing unprofitable projects at the design stage.
By visualizing material costs, processing costs, depreciation, outsourcing, and losses, suppliers can:
- Assess profitability before order acceptance
- Design profit-oriented manufacturing processes
- Strengthen negotiation power with OEMs
This enables a shift away from “loss after order” business models.
For OEMs
OEMs benefit from:
- Higher accuracy in profit forecasting
- Prevention of unprofitable programs
- Optimized end-to-end product design
Conclusion: Profit-Driven Cost Planning with SAP
This article outlined the overall framework of SAP-based cost planning and its application in:
- The Idea / Concept Phase
- The Design / Development Phase
SAP’s greatest strength lies in enabling:
Closed-loop cost management
from concept through mass production and beyond.
As a result:
- Tier-1 suppliers can embed profitability from the design stage
- OEMs can manage program profitability with high precision
This leads to sustainable competitive advantage in the automotive industry.
