1. Fondasi: Procurement vs Sourcing vs Purchasing
Setelah memahami customer accommodation di Sesi 03, kini kita masuk ke sisi hulu supply chain: procurement dan strategic sourcing.
Menurut Council of Supply Chain Management Professionals (CSCMP), procurement adalah proses end-to-end untuk memperoleh barang/jasa dari sumber eksternal.
Perbedaan Purchasing, Procurement, dan Strategic Sourcing:
| Aspek | Purchasing | Procurement | Strategic Sourcing |
|---|---|---|---|
| Fokus | Transaksi pembelian | Proses end-to-end | Value creation jangka panjang |
| Time Horizon | Harian/mingguan | Bulanan/tahunan | 3-10 tahun |
| Objective | Place order, receive goods | Efficient acquisition | TCO reduction, risk mitigation, innovation |
| Supplier Relationship | Transactional | Tactical | Strategic partnership |
| Decision Criteria | Price only | Price + quality + delivery | TCO + innovation + risk + sustainability |
Astra mengelola procurement untuk 5 lini bisnis dengan total spend Rp 150+ triliun/tahun:
• Central Procurement: Strategic sourcing untuk komoditas umum
• Business Unit Procurement: Sourcing spesifik per lini bisnis
• Category Management: 25 kategori procurement dengan dedicated category manager
Hasil: Procurement cost saving Rp 3.5 triliun/tahun, supplier on-time delivery 96%.
2. Make vs Buy Decision: Outsourcing Strategy
Salah satu keputusan paling strategis dalam strategic sourcing adalah “Make or Buy” – apakah memproduksi sendiri atau outsourcing ke supplier.
Framework Make vs Buy Decision:
| Faktor | Make (In-House) | Buy (Outsource) |
|---|---|---|
| Core Competency | Jika merupakan core competency | Jika bukan core competency, supplier lebih ahli |
| Cost | Jika biaya internal lebih rendah | Jika supplier bisa lebih murah |
| Quality Control | Jika quality critical | Jika quality standar |
| IP Protection | Jika ada IP/paten yang perlu dilindungi | Jika tidak ada IP concern |
| Capacity | Jika punya spare capacity | Jika kapasitas internal terbatas |
TMMI memproduksi Kijang, Avanza dengan 200+ komponen per unit:
• Make (30%): Engine assembly, body welding, final assembly (core competency)
• Buy (70%): Electrical components (Denso), tires (Bridgestone), glass (Asahi)
Hasil: Production cost 25% lebih rendah, defect rate < 50 PPM, time-to-market 18 bulan.
3. Manufacturing Strategies: MTM, MTO, ATO, ETO
Perusahaan manufaktur memilih strategi produksi berdasarkan trade-off antara efisiensi dan responsivitas:
4 Manufacturing Strategies:
| Strategi | Definisi | Lead Time | Inventory | Cocok Untuk |
|---|---|---|---|---|
| MTM (Make-to-Stock) | Produksi berdasarkan forecast | Sangat pendek | Tinggi (finished goods) | Functional products (Indomie) |
| MTO (Make-to-Order) | Produksi setelah ada order | Medium (1-4 minggu) | Rendah (raw material) | Custom products (furniture) |
| ATO (Assemble-to-Order) | Komponen di-stock, assembly setelah order | Pendek (1-3 hari) | Medium (components) | Modular products (Dell PC) |
| ETO (Engineer-to-Order) | Design & produksi setelah order | Panjang (3-12 bulan) | Sangat rendah | Highly custom (kapal) |
4. Total Cost of Ownership (TCO)
Total Cost of Ownership (TCO) adalah metodologi untuk menghitung seluruh biaya yang terkait dengan pengadaan barang/jasa selama siklus hidupnya, bukan hanya harga pembelian.
Komponen TCO:
- Pre-Transaction (7-12%): Need identification, supplier search, negotiation
- Transaction (63-80%): Purchase price, transportation, quality inspection
- Post-Transaction (18-38%): Inventory carrying, maintenance, quality failures, disposal
TCO 25 tahun untuk pembangkit 100 MW:
• Coal Plant: CAPEX $120M + Fuel $800M + O&M $250M = $1,350M total
• Solar Plant: CAPEX $180M + Fuel $0 + O&M $80M = $280M total
Insight: Solar 79% lebih murah di TCO meskipun CAPEX 50% lebih mahal!
5. Kraljic Matrix: Kategorisasi Item Procurement
Kraljic Matrix (1983) adalah framework untuk mengkategorisasi item procurement berdasarkan 2 dimensi: (1) Profit Impact, dan (2) Supply Risk.
4 Kategori Kraljic Matrix:
| Kategori | Karakteristik | % Spend | Strategi |
|---|---|---|---|
| Strategic Items (High Risk, High Value) | Custom, few suppliers, critical | 60-70% | Strategic partnership |
| Bottleneck Items (High Risk, Low Value) | Specialized, supply uncertainty | 5-10% | Secure supply, safety stock |
| Leverage Items (Low Risk, High Value) | Commodity, many suppliers | 15-25% | Competitive bidding |
| Non-Critical Items (Low Risk, Low Value) | Standard, easy to source | 3-5% | Efficient processing |
• Strategic (65%): Tepung terigu, minyak sawit → Partnership Bogasari & Wilmar
• Bottleneck (8%): Spare part import → Safety stock 60 hari
• Leverage (20%): Gula, garam → E-auction, cost saving 12%
• Non-Critical (7%): ATK → P-card, admin cost turun 60%
6. Supplier Selection: 10 Dimensi Evaluasi
Supplier selection adalah keputusan kritis. Berikut 10 dimensi evaluasi yang komprehensif:
10 Dimensi Supplier Evaluation:
| # | Dimensi | Bobot | Metrik |
|---|---|---|---|
| 1 | Quality | 20-25% | PPM defect, ISO certification |
| 2 | Cost | 20-25% | Price competitiveness, TCO |
| 3 | Delivery | 15-20% | OTD %, lead time |
| 4 | Technology | 10-15% | R&D investment, patents |
| 5 | Financial Stability | 5-10% | Credit rating, profitability |
| 6-10 | Capacity, Service, ESG, Risk, Cultural Fit | 5-10% each | Various metrics |
Weighting untuk supplier komponen:
• Quality: 35% (critical for safety)
• Delivery: 25% (JIT requirement)
• Cost: 20% (competitive)
• Technology: 10%
• Financial: 5%
• Service: 5%
Hasil: Defect rate 35 PPM, OTD 98%, local content 80%.
7. Supplier Relationship Management (SRM)
SRM adalah pendekatan sistematis untuk mengelola hubungan dengan supplier guna memaksimalkan value.
4 Level Supplier Relationship:
| Level | Karakteristik | Durasi | Cocok Untuk |
|---|---|---|---|
| Arm’s Length (Transaksional) | Price-driven, multiple suppliers | 1 tahun | Non-critical items |
| Cooperative | Some info sharing, fewer suppliers | 2-3 tahun | Leverage items |
| Collaborative | Deep sharing, joint improvement | 3-5 tahun | Strategic items |
| Strategic Alliance | Full transparency, joint R&D | 5-10+ tahun | Most critical items |
• Strategic Partners (50 suppliers): 60% spend, quarterly business review
• Preferred Suppliers (300): 25% spend, bi-annual review
• Approved Suppliers (1,000): 12% spend, annual review
• Transactional (1,650): 3% spend, automated
Hasil: Cost saving Rp 800 miliar/tahun, 50+ new products dari joint R&D.

FAQ Strategic Sourcing & Procurement
Apa perbedaan utama antara purchasing dan strategic sourcing?
Purchasing fokus pada transaksi pembelian harian dengan kriteria harga terendah. Strategic sourcing fokus pada value creation jangka panjang dengan pertimbangan TCO, innovation, risk mitigation, dan partnership development.
Kapan sebaiknya perusahaan memilih make (in-house) vs buy (outsource)?
Pilih make jika merupakan core competency, ada IP yang perlu dilindungi, atau biaya internal lebih rendah. Pilih buy jika supplier lebih ahli, bukan core competency, atau butuh fleksibilitas kapasitas.
Bagaimana cara menerapkan Kraljic Matrix dalam procurement?
Kategorikan item berdasarkan profit impact (tinggi/rendah) dan supply risk (tinggi/rendah). Strategic items butuh partnership, bottleneck items butuh safety stock, leverage items butuh competitive bidding, non-critical items butuh efficient processing.
Mengapa TCO lebih penting dari purchase price?
TCO mencakup seluruh biaya selama siklus hidup (pre-transaction, transaction, post-transaction). Seringkali supplier dengan harga lebih tinggi punya TCO lebih rendah karena quality lebih baik, maintenance lebih murah, dan reliability lebih tinggi.
