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)

  1. Sales Forecasting – predict customer demand (A in diagram)
  2. Sales & Operations Planning (SOP) – balance demand with capacity (B in diagram)
  3. Demand Management – create Master Production Schedule, splits monthly into finer periods (C in diagram)
  4. Materials Requirements Planning (MRP) – determine raw material needs using BOM (C in diagram)
  5. Detailed Scheduling – consider capacity and labor; longer runs increase capacity and inventory (D in diagram)

Sales Order Process (6 Steps)

  1. Pre-Sales Activities – customer inquiries, quotations (price requests)
  2. Sales Order Processing – record items, pricing, credit checks, discounts applied
  3. Inventory Sourcing – ATP checks, delivery confirmation
  4. Delivery – release warehouse documents (pick, pack, ship instructions)
  5. Billing – automatic invoice generation
  6. 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

  1. Integrated Information Systems – common database, good for production planning
  2. Real-time Data – immediate updates across all areas
  3. Modular Design – individual programs working together
  4. Best Practices – built-in efficient processes
  5. Configurable – customizable to company requirements
  6. Common Database – single source of truth
  7. Open Architecture – third-party integration capability
  8. 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
