Cost Reduction & Control: Methods, Tools & Real-World Applications

TAKEAWAYS:

• Cost reduction focuses on eliminating waste and inefficiencies before they occur (e.g., process redesign), while cost control monitors and corrects deviations after they happen (e.g., variance analysis).
• The 80/20 rule (Pareto principle) identifies 20% of activities causing 80% of costs—critical for prioritizing reduction efforts (e.g., Daraz’s inventory holding costs).
• Value analysis questions every cost: "Does this add value to the customer?" (e.g., Ncell’s network optimization to cut maintenance costs).
• Lean tools (5S, Kaizen, Kanban) visualize workflows to spot bottlenecks (e.g., Kathmandu’s retail floor layout reducing idle staff time).
• Standard costing sets benchmarks for variances (e.g., a bakery’s flour usage per loaf), while budgetary control compares actual vs. planned costs monthly.
• Exam tip: Always link numerical answers to real scenarios (e.g., "If NTC reduces fuel costs by 10%, how does this affect their per-km cost?").

1. Definitions: Cost Reduction vs. Cost Control

graph LR
    A["Cost Reduction"] -->|"Proactive"| B["Eliminate waste\nbefore it occurs"]
    A --> C["Process redesign\nValue analysis\nPreventive tools"]
    D["Cost Control"] -->|"Reactive"| E["Monitor & correct\nafter deviations"]
    D --> F["Variance analysis\nBudgetary control\nPost-hoc audits"]
    G["Both"] --> H["Use standard costs\nLean principles\nContinuous improvement"]

Key difference:

• Reduction = Preventing inefficiencies (e.g., redesigning a Pathao driver’s route to save fuel).
• Control = Detecting and fixing inefficiencies (e.g., comparing actual fuel costs vs. budget).

2. Methods for Cost Reduction

A. Value Analysis (Value Engineering)

How it works:

1. Question every cost: "Is this necessary? Does it add value to the customer?"
2. Alternatives: Use cheaper materials, simplify processes, or redesign products.
3. Example: Khalti’s transaction fees
   • Original: Rs. 5 per transaction (fixed cost).
   • Reduction: Introduced bulk discounts for merchants (e.g., Rs. 3 for >100 transactions/month).
   • Result: 30% drop in per-transaction cost for high-volume users.

Worked Example: Daraz’s Packaging Costs

    title Daraz Packaging Cost Breakdown (Before/After)
    "Boxes (60%)" : 12
    "Tape (15%)" : 3
    "Labels (25%)" : 5

B. Process Simplification (Lean Principles)

Tools:

1. 5S Methodology: Sort, Set in order, Shine, Standardize, Sustain.
   • Example: NTC’s bus depot
     • Before: Tools scattered, drivers wasted 20 mins/day searching for parts.
     • After: Color-coded storage + checklists → 15% faster turnaround.
2. Kaizen (Continuous Improvement): Small, incremental changes.
   • Example: Nepal Bank’s loan processing
     • Reduced approval time from 10 days → 3 days by digitizing forms.
3. Kanban: Visual signals to pull inventory (e.g., Big Mart’s stock alerts).

3. Cost Control Techniques

A. Standard Costing and Variance Analysis

How it works:

1. Set standards: Expected cost per unit (e.g., flour per kg of bread).
2. Compare actuals: Calculate variances (favorable/unfavorable).
3. Act: Investigate and correct deviations.

Worked Example: Kathmandu’s Bakery

B. Budgetary Control

Steps:

1. Set budgets: Departmental cost limits (e.g., Ncell’s monthly maintenance budget).
2. Monitor: Compare actual spending vs. budget (e.g., monthly reports).
3. Adjust: Reallocate funds or cut non-essential costs.

Example: Nepal Telecom’s Tower Maintenance

4. Real-World Applications

A. eSewa’s Cost Reduction

• Problem: High transaction failure rates (15%) due to manual verification.
• Solution:
  • Value analysis: Eliminated redundant steps (e.g., physical signature checks).
  • Automation: Integrated OTP verification → cost per transaction dropped by 40% (from Rs. 8 to Rs. 4.8).

B. Pathao’s Driver Cost Control

• Method: Activity-Based Costing (ABC)
  • Tracked costs per driver:
    • Fuel: Rs. 200/day
    • Vehicle depreciation: Rs. 50/day
    • Total: Rs. 250/day
  • Reduction: Optimized routes using GPS → 10% fuel savings.

C. NEPSE’s Trading Costs

• Challenge: High brokerage fees (0.5% per trade).
• Solution:
  • Batch processing: Grouped small trades into bulk orders.
  • Result: Reduced per-trade cost from Rs. 500 → Rs. 300.

5. Exam Tip: How to Score Full Marks

1. Link theory to numbers:
   • "If NTC reduces fuel costs by 10%, the per-km cost drops from Rs. 12 to Rs. 10.80, saving Rs. 120,000/month for 10,000 km."
2. Use Nepali examples:
   • Always tie answers to eSewa, Daraz, Ncell, or local businesses.
3. Show calculations:
   • For variance analysis, always provide a table with Dr/Cr columns.
4. Compare methods:
   • "While standard costing helps identify variances, value analysis prevents them by redesigning processes."

Past Exam Pattern:

• Short answers: Define terms (e.g., "What is Kaizen?").
• Numericals: Calculate variances or savings (e.g., "If a company reduces material waste by 20%, how much is saved?").
• Case studies: Analyze a scenario (e.g., "How would you reduce costs for Harati Yatayat Sewa?").
