**A: Master Data** — 25 man-days | Rp 50 jt | ROI: 98% (3 Yr)

#### Info

Dependency | Core Man-days | 25 Cost HPP | Rp 50.000.000 Monthly Benefit | Rp 2.750.000 Payback Period | 18.2 bulan ROI 1 Year | -45% ROI 3 Year | 98%

#### ROI Explanation

**ROI 1 Tahun: -45% (Belum Balik Modal)**

Master Data memiliki ROI negatif di tahun pertama karena modul ini adalah **foundation/enabler** - value utamanya bukan dari savings langsung, melainkan dari **enabling modul lain** untuk berfungsi. Tanpa Master Data yang baik, modul B-Z tidak bisa beroperasi.

> **Kenapa tetap wajib dibangun:**
>
> - Semua modul lain bergantung pada Master Data
> - Savings Rp 2.75 juta/bulan berasal dari eliminasi duplikasi data dan error input
> - Real value: **multiplier effect** - Master Data yang akurat meningkatkan efektivitas semua modul downstream

#### Reasoning

Master Data adalah fondasi dari seluruh sistem inventory. Tanpa data master yang terstruktur, tidak mungkin melakukan tracking stock, transaksi, atau reporting. Modul ini WAJIB diimplementasi pertama karena semua modul lain bergantung padanya.

#### User Stories

ID | Role | Story | Acceptance Criteria A-01 | Admin | Saya ingin menambah item baru agar bisa di-track dalam sistem | Item tersimpan dengan kode unik, nama, kategori, UoM A-02 | Admin | Saya ingin membuat kategori item agar item terorganisir | Kategori bisa hierarchical (parent-child) A-03 | Admin | Saya ingin mendaftarkan supplier agar bisa tracking asal barang | Supplier memiliki info kontak, alamat, terms A-04 | Admin | Saya ingin setup warehouse/lokasi penyimpanan | Warehouse bisa multi-level (warehouse > zone > rack > bin) A-05 | Admin | Saya ingin define Unit of Measure dan konversinya | UoM dengan conversion factor (1 box = 12 pcs) A-06 | User | Saya ingin mencari item dengan cepat | Search by kode, nama, kategori, barcode A-07 | Admin | Saya ingin import data master dari Excel | Bulk import dengan validasi dan error report

#### Benefit Analysis

Metric | Sebelum | Sesudah | Improvement Waktu cari item | 5-10 menit (manual) | 5 detik | 99% faster Data duplikasi | 15-20% | <1% | 95% reduction Error input | 10% transaksi | <2% | 80% reduction

> **Kenapa ROI sebenarnya lebih tinggi:** Kalkulasi di atas konservatif. E-commerce membuka market B2C yang sebelumnya tidak terjangkau. Potensi revenue growth bisa 20-50% untuk bisnis yang belum online.

#### Reasoning

E-Commerce adalah **revenue enabler** yang membuka channel penjualan 24/7. Untuk pabrik/distributor yang selama ini hanya B2B, modul ini memungkinkan direct-to-consumer (D2C) sales dengan margin lebih tinggi.

#### User Stories

ID | Role | Story | Acceptance Criteria AA-01 | Customer | Saya ingin browse produk dan melihat harga | Product catalog dengan search, filter, kategori AA-02 | Customer | Saya ingin melihat ketersediaan stock | Real-time stock status (available/out of stock) AA-03 | Customer | Saya ingin menambah produk ke keranjang | Cart dengan qty adjustment, remove item AA-04 | Customer | Saya ingin checkout dan bayar | Multiple payment methods (transfer, VA, e-wallet) AA-05 | Customer | Saya ingin track pesanan saya | Order status: confirmed, processing, shipped, delivered AA-06 | Admin | Saya ingin manage produk yang dijual online | Product management dengan harga, foto, deskripsi AA-07 | Admin | Saya ingin set harga berbeda untuk B2B vs B2C | Price tier: retail, wholesale, member AA-08 | Admin | Saya ingin promo dan discount | Voucher, flash sale, bundle pricing AA-09 | Sales | Saya ingin manage B2B customer accounts | Company registration, credit terms, PO system AA-10 | Manager | Saya ingin lihat sales analytics | Revenue, conversion rate, top products, customer segments

#### Benefit Analysis

Metric | Sebelum | Sesudah | Improvement Sales channels | B2B only (offline) | B2B + B2C (online) | +1 channel Operating hours | 8 jam/hari | 24/7 | 3x availability Order processing | 30 min/order (manual) | 5 min/order (auto) | 83% faster Order errors | 10% | 2% | 80% reduction Market reach | Local B2B | Nationwide B2C | Unlimited

**Total Savings: Rp 25.1 juta/bulan** (tidak termasuk revenue growth dari new channel)



**AB: Expedisi Internal** — 35 man-days | Rp 70 jt | ROI: 11% | ADD-ON

#### Info

Dependency | AA (E-Commerce), P (Delivery) Man-days | 35 Cost HPP | Rp 70.000.000 Monthly Benefit | Rp 6.500.000 Payback Period | 10.8 bulan ROI 1 Year | 11% ROI 3 Year | 234%

#### ROI Explanation

**ROI 1 Tahun: 11% - Lower ROI tapi Full Control**

Expedisi Internal memiliki ROI lebih rendah karena **membutuhkan operational investment** (drivers, vehicles, fuel), tapi memberikan **full control** atas delivery experience:

- **Delivery Fee Margin (Rp 5 juta/bulan):** 500 deliveries x Rp 10.000 margin per delivery.
- **Driver Utilization (Rp 1 juta/bulan):** Route optimization mengurangi waktu dan fuel.
- **Customer Satisfaction (Rp 500.000/bulan):** Control over delivery timing = fewer complaints = repeat orders.

> **Best for:** High-volume local delivery, same-day delivery requirement, premium delivery service.\
> **Requires:** Drivers (gaji Rp 4-5 jt/bulan), vehicles (motor/mobil), fuel, maintenance.

#### Reasoning

Expedisi Internal untuk bisnis yang membutuhkan **kontrol penuh** atas pengiriman. Cocok untuk same-day delivery, perishable goods, atau premium service dimana customer experience adalah prioritas.

#### User Stories

ID | Role | Story | Acceptance Criteria AB-01 | Admin | Saya ingin manage driver | Driver profile, status, performance AB-02 | Admin | Saya ingin manage kendaraan | Vehicle list, capacity, maintenance schedule AB-03 | Dispatcher | Saya ingin assign delivery ke driver | Auto-assign atau manual assign AB-04 | Dispatcher | Saya ingin optimize route | Multi-stop route planning AB-05 | Driver | Saya ingin lihat delivery tasks di HP | Mobile app dengan navigation AB-06 | Driver | Saya ingin capture proof of delivery | Photo, signature, timestamp AB-07 | Customer | Saya ingin track driver secara real-time | Live tracking dengan ETA AB-08 | Manager | Saya ingin lihat delivery performance | On-time rate, delivery cost, driver performance

#### Benefit Analysis

Metric | Sebelum | Sesudah | Improvement Delivery control | 3rd party dependent | Full control | 100% Same-day delivery | Not possible | Available | New capability Route efficiency | Driver decision | Optimized | 20-30% faster Delivery margin | 0 (pass-through) | Rp 10k/delivery | New revenue

**Total Savings: Rp 6.5 juta/bulan** (sebelum operational cost)
