Function Point Estimation Procedure:

1. Identify Function Types
   - ILF (Internal Logical File)
   - EIF (External Interface File)
   - EI (External Input)
   - EO (External Output)
   - EQ (External Inquiry)

2. Assess Function Complexity
   - Low, Average, High
   - Based on DET (Data Element Types) and RET/FTR criteria

3. Calculate Unadjusted Function Points
   - Apply weights based on function type and complexity

   Weights by Function Type:
   ILF: Low=7, Average=10, High=15
   EIF: Low=5, Average=7, High=10
   EI:  Low=3, Average=4, High=6
   EO:  Low=4, Average=5, High=7
   EQ:  Low=3, Average=4, High=6

4. Apply Adjustment Factors
   - Scale adjustment, application type adjustment, language adjustment, etc.

5. Calculate Final Development Cost
   Cost per Function Point x Adjusted Function Points = Development Cost

# Man-Month Based Cost Estimation Example
labor_cost_estimation:
  grade_based_monthly_rates: # 2026 baseline (illustrative)
    professional_engineer: 12,500,000 KRW/month
    senior_engineer: 10,800,000 KRW/month
    advanced_engineer: 9,200,000 KRW/month
    intermediate_engineer: 7,600,000 KRW/month
    junior_engineer: 5,800,000 KRW/month

  staffing_plan:
    PM_senior: 12 person-months
    PL_advanced: 12 person-months
    analysts_advanced: 9 person-months (3 persons x 3 months)
    designers_intermediate: 12 person-months (4 persons x 3 months)
    developers_intermediate: 48 person-months (8 persons x 6 months)
    QA_intermediate: 9 person-months (3 persons x 3 months)
    DBA_advanced: 12 person-months

  direct_labor_total: approximately 900,000,000 KRW

total_project_cost:
  direct_labor: 900,000,000 KRW
  overhead: 990,000,000 KRW # 110% of direct labor
  technical_fee: 378,000,000 KRW # 20% of (direct labor + overhead)
  direct_expenses: 150,000,000 KRW # equipment, SW licenses, training
  total_cost: 2,418,000,000 KRW
  profit: 241,800,000 KRW # 10% of total cost
  total_project_budget: 2,659,800,000 KRW # approximately 2.66 billion KRW

ROI Calculation Framework:

1. Tangible Benefits
   - Business processing time reduction: 200M KRW/year (labor savings)
   - Manual error reduction: 50M KRW/year (rework cost savings)
   - Operational efficiency: 300M KRW/year (process automation)
   - Subtotal: 550M KRW/year

2. Intangible Benefits
   - Improved decision-making speed
   - Enhanced customer satisfaction
   - Strengthened data-driven management capability
   - Reduced regulatory compliance risk

3. ROI Calculation
   5-year total benefits: 550M KRW x 5 years = 2,750M KRW
   5-year TCO: 6,090M KRW

   Simple ROI = (Total Benefits - Total Cost) / Total Cost
              = (2,750 - 6,090) / 6,090
              = -54.8%

   However, including intangible benefits and opportunity costs:
   Adjusted total benefits: 1,500M KRW/year (including intangible benefits)
   5-year adjusted benefits: 7,500M KRW

   Adjusted ROI = (7,500 - 6,090) / 6,090 = 23.2%
   Break-even Point (BEP): Approximately 4 years and 1 month

# SLA Definition Example
service_level_agreement:
  service_availability:
    target: 99.95%
    measurement_period: monthly
    excluded_time: planned maintenance (2nd Sunday monthly 02:00-06:00)
    calculation: '(Total service time - Downtime) / Total service time x 100'
    penalties:
      99.90_to_99.95: 5% reduction of monthly maintenance fee
      99.50_to_99.90: 10% reduction of monthly maintenance fee
      below_99.50: 20% reduction of monthly maintenance fee

  response_time:
    online_transactions: average under 3 seconds (under 5 seconds during peak)
    batch_processing: completed within designated time window
    report_generation: within 30 seconds

  incident_response:
    critical: response within 30 minutes, resolution within 4 hours
    major: response within 1 hour, resolution within 8 hours
    minor: response within 4 hours, resolution within 24 hours
    informational: response within 8 hours, resolution within 3 business days

SLA Improvement Cycle (PDCA):

Plan
  - Define SLA metrics and target levels
  - Establish monitoring framework
  - Stakeholder alignment

Do
  - SLA-based service operations
  - Real-time monitoring
  - Incident response process execution

Check
  - Monthly/quarterly SLA achievement analysis
  - Root cause analysis for non-compliance items
  - Trend analysis and forecasting

Act
  - Identify and execute improvement initiatives
  - Adjust SLA standards (as needed)
  - Optimize operational processes
