Business Operations & ERP Fundamentals
Production Calculations
Production Capacity: 200 bars/minute = 12,000 bars/hour = 3,000 lbs/hour
Daily Production Formulas:
- Weekdays only: 5 days × 8 hours × 12,000 bars/hour
- Weekdays + Saturday: 6 days × 8 hours × 12,000 bars/hour
- Full week: 7 days × 8 hours × 12,000 bars/hour
Monthly Production: Working days × daily capacity
MRP Inventory Formula: On Hand = Previous On Hand + Scheduled Receipts – Gross Requirements
Place Planned Orders considering lead time (e.g., 2-week lead time means order in week 2 for week 4 need)
Production Approaches
Make-to-Stock: Made for inventory before orders (most consumer products)
Make-to-Order: Produced for specific customer orders
Assemble-to-Order: Assembled from inventory components for specific orders
Supply Chain Performance Metrics
On-time Performance: How often a supplier meets agreed delivery dates
Initial Fill Rate: Percentage of order provided in the first shipment
Initial Order Lead Time: Time needed for a supplier to fill an order
Cash-to-Cash Cycle Time: Payment to collection timespan

Business Processes and Concepts
Production Planning Process (5 Steps)
- Sales Forecasting – predict customer demand (A in diagram)
- Sales & Operations Planning (SOP) – balance demand with capacity (B in diagram)
- Demand Management – create Master Production Schedule, splits monthly into finer periods (C in diagram)
- Materials Requirements Planning (MRP) – determine raw material needs using BOM (C in diagram)
- Detailed Scheduling – consider capacity and labor; longer runs increase capacity and inventory (D in diagram)
Sales Order Process (6 Steps)
- Pre-Sales Activities – customer inquiries, quotations (price requests)
- Sales Order Processing – record items, pricing, credit checks, discounts applied
- Inventory Sourcing – ATP checks, delivery confirmation
- Delivery – release warehouse documents (pick, pack, ship instructions)
- Billing – automatic invoice generation
- Payment – customer remittance, cash debited, A/R credited
Four Core Functional Areas
Marketing & Sales: Product development, pricing, promotion, orders, forecasts
Supply Chain Management: Manufacturing, purchasing, production planning, logistics
Accounting & Finance: Transaction recording, cost control, budgeting, cash flow
Human Resources: Recruiting, training, payroll, benefits, compliance
Business Process vs. Business Function
Business Function: Activities within a single department
Business Process: Cross-departmental activities creating customer value
Benefits of Process Thinking: Customer focus, integration, efficiency
Management Organization: Cross-functional teams, process ownership
ERP System Characteristics
- Integrated Information Systems – common database, good for production planning
- Real-time Data – immediate updates across all areas
- Modular Design – individual programs working together
- Best Practices – built-in efficient processes
- Configurable – customizable to company requirements
- Common Database – single source of truth
- Open Architecture – third-party integration capability
- Workflow Automation – automated business processes
Document Flow
Definition: Linked set of document numbers related to the order process
Features: Electronic evidence, unique numbers, audit trail, drill-down capability
Master Data Concepts
Customer Master Data: Available to multiple modules, not just SD
Material Master Data: Available to multiple modules, not just MM
Benefits: Eliminates re-entry, ensures consistency, enables automation
Supply Chain Concepts
Traditional Supply Chain: Information passed reactively, takes weeks/months
ERP Benefits: Rapid information transmission to all members
Supply Chain Definition: Raw materials to finished products on the store shelf
Important Industries: Manufacturing, retail, automotive, electronics
Unexpected Demand Impact: Inventory depletion, overtime costs, material shortages
MRP Process Details
Purpose: Determines the amount and timing of raw material orders (not finished goods schedule)
Key Factors: Lead times help determine material ordering, not goods transfer
BOM Usage: List of ingredients/materials needed for production
Lot Sizing: Affects production runs and inventory levels
Accounting Integration
Financial Accounting: External reporting (Balance Sheet, Income Statement)
Managerial Accounting: Internal decision-making, cost analysis, budgeting
Three Cost Elements: Raw materials + Direct labor + Overhead
Integration Benefits: Real-time posting, automatic updates, audit trails
Human Resources Processes
Core Functions: Recruiting, hiring, training, payroll, benefits, compliance
SAP HR Distinctions:
- Task – specific job responsibility
- Job – general classification of tasks
- Position – individual employee assignment
- Person – individual holding position
Key Processes: Payroll runs, succession planning (key employees only), short list creation
Communication: HR communicates salary, benefit, and policy changes
Employee Turnover: Tied to job satisfaction and compensation (not just communication)
ERP Implementation Success Factors
Success: Management commitment, proper planning, comprehensive training, user involvement
Failure: People problems, unrealistic expectations, insufficient planning, inadequate training
Detailed Scheduling Effects
Longer Production Runs: Increase available capacity (fewer setups) + increase inventory levels
Shorter Production Runs: Lower inventory levels but more setups required
