I. BACKGROUND Vehicle sales and production in domestic market will reach 1 million unit/years in 2014. At the same time, competition among Car Brands is getting more severe. Because of that Toyota keep trying to improvement, yet price of material often has increase. So division Purchasing make a plan to get cost reduction to balance impact cost up due to material cost increasing (maintain competitives cost)
II. Analysis Toyota Bisnis Practices Step 1 Clarify the Problem
Step 2 . Breakdown Analysis
< Ultimate Goal >
< By raw material>
< by supplier >
SEAT 13 %
TBINA 0.00%
to be the best cost in Asia region
< Point of occurance >
material cost
SGT: - 1.11 % (-Rp 3,605 B)
Achieve 2011 cost reduction : 2.5 % Rp 105,203 B
IR3 : -0.52% (-Rp 791 B)
Interior and electrical section - 1.63 % (- Rp 33, 822 B)
RESIN 6%
Buyer still no have actual information about material and process
depreciation
FTR:- 1.05 %(-Rp ( p 914 B)) RUBBER 4%
IRC:- 0.54 %(- Rp 398 B) ITG:- 0.5 % (-Rp 271 B)
Service and component section + 0.2 % (+ Rp 580 B)

< Machine >
Machine not influence to get information

data that affect CR not enough (raw data)
no actual methode to get information that influence CR
buyer experience is low
no collection data which content with CR
no training for new buyer
ii. Apakah mungkin dikurangi ketebalan (thickness ) part
Buyer have many work and don't have time to arrange
c. Pecahkan masalah yang ada berdasarkan aspek-aspek yang mungkin Seperti design , metode manufacturing , tenaga kerja, biaya mold , dan lain-lain Rencana perbaikan
< Man >
i. Pemeriksaan untuk CR terhadap semua aspek yang mungkin termasuk material, bentuk. ii. Kembangkan teknologi atau teknik baru e. Evaluasi Adakan evaluasi mengenai hubungan antara biaya dan teknik, kualitas, produksi, pasar, dan lain-lain
no manual book
2. Cara untuk mengembangkan ide a. b.
Benchmarking atau studi banding Diskusi
c.
Genchi Genbutsu
3. Proses cost a. Cek berapa mesin tonnage yang sebaiknya digunakan
< Root Cause >
b. Cek berapa lama mesin tersebut sudah digunakan. Apabila bukan mesin baru bisa negosiasikan harganya. c. Cek cycle time dengan cara mengambil beberapa sample part yang sedang dibuat
< Countermeasures >
d. Cek apakah cycle time atau mesin tonnage yang digunakan dapat diganti e. Apakah mungkin coating suatu part tersebut dihilangkan
Step 7 Evaluation process and result
Before improvement
no information about material
no information about process make a part
no standarization to find CR
After countermeasures
Evaluation result
there is a information or guidance about material (specification material, consumption resin material, and source raw material) All data about material, process, cost, there is a information or guidance about process and how to get CR already (step to make part with arrange injection, how to determine machine tonnage, cycle time, and cost) there is a standarisasi

Step 4 Root Cause Analysis
Analisis biaya i.Cari biaya apa yang terbesar diantara part yang ada?
ii.Bandingkan dengan part dari supplier lain yang sejenis b. Cari fungsi asli dari part tersebut Dengan diketahuinya fungsi asli part dapat ditentukan raw material yang tepat i. Apakah mungkin mengganti raw material ke grade yang lebih rendah (lebih murah)
