LEAN MANUFACTURING LO - 1
Lean Manufacturing
Right Product
Right Quantity
Exact Time
Lowest Possible Cost
An approach designed to eliminate waste and maximize customer value.
3
Significant Improvement
Better Quality
Reduce Lead Time
Increased Productivity
Lower Manufacturing Time
Major Reduction in Inventory
Reduced Setup Time
Increase Production Rates
4
Principles of Lean Thinking
1
Precisely specify value by each particular product.
2
Identify the “value stream” for each.
3
Make value flow without interruption.
4
Let the customer pull value from the producer.
5
Pursue perfection

1. Value Of Product
•
Assesing value is externally oriented and not internally generated.
•
Only value-added features should be produced, non-valueadded activities should be eliminated
6
2. Value Stream
•
Fulfillment value stream : providing current products to current customers.
•
New product value stream : developing new products for new customers.
•
Allowes management to identify waste.
•
2 types non-value-added activities are the source of waste : – Activities avoidable in short run – Activities unavoidable in the short run due to current technology or production method.

3. Value Flow
• This approach requires significant move time and wait time as each batch moves from one department to another and waits for its turn if theres a batch-inprocess in front of it. • Reduce setup/changeover time • Cellular manufacturing

4. Pull Value • Each operation produces only what is necessary to satisfy the demand of succeding operation.
• JIT purchasing.

PURSUE PERFECTION Tujuannya adalah menghasilkan produk berkualita s tinggi dan berbiaya rendah dengan jumlah waktu paling minimum. Untuk mencapai tujuan ini, produsen lean harus mengidentifikasi dan meniadakan berbagai bentuk WASTE. FORMS AND SOURCES OF WASTE • Produk cacat • Produk berlebih barang yang tidak dibutuhkan • Persediaan barang yang menunggu diproses atau digunakan • Pemrosesan yang tidak dibutuhkan • Perpindahan karyawan yang tidak perlu • Transportasi barang yang tidak perlu • Waktu tunggu • Desain barang dan jasa yang tidak memenuhi kebutuhan pelanggan
13
EMPLOYEE EMPOWERMENT Keterlibatan karyawan sangat penting dalam mengidentifikasi dan mengelimiasi semua bentuk waste. Dalam lean manufacturing, manajer menerima saran-saran dari para pekerja dalam rangka meningkatkan produktifitas dan efisiensi penggunaan biaya
TOTAL QUALITY CONTROL TQC adalah pengendalian yang dilakukan untuk menilai kualitas produk yang dihasilkan agar perancangan produk dan proses perakitan bebas dari kesalahan.
14
INVENTORIES Jumlah inventory dapat dikontrol dengan menggunakan cellular manufacturing, low setup times, JIT purcahsing, dan demand full system
ACTIVITY-BASED MANAGEMENT Process value analysis adalah suatu metodologi untuk mengidentifikasi dan mengeliminasi aktivitas-aktivitas yang tidak memberikan nilai tambah.

LEAN ACCOUNTING LO - 2
FOCUSED VALUE STREAM AND TRACEABILITY OF OVERHEAD COSTS
Menggunakan metode penentuan biaya terhadap individual products secara direct tracing
LEAN ACCOUNTING 1

PRODUCT COSTING
3
Contoh : cost of the value stream are $800,000 for the month of January and the output for January is 5,000 units. So, the unit cost is $160 per unit ($800,0000/5,000)
4
VALUE STREAM COSTING WITH MULTIPLE PRODUCTS
VALUE-STREAM LIMITATIONS AND PROBLEMS Bisa saja satu pekerja bekerja pada lebih dari satu value stream. Sehingga biaya tenaga kerja tersebut harus dialokasikan ke masing-masing value stream berdasarkan proporsi waktu yang dihabiskan pada tiap value stream
VALUE STREAM REPORTING CONTOH
Value Stream Product Cost = 5
Total value stream cost of period units shipped of period CONTOH

CONTOH VALUE STREAM COSTING WITH MULTIPLE PRODUCTS During the week of April 6, Allen Autoparts produced and shipped 1,000 units of Model C and 4,000 units of Model D, for a total 5,000 units. Using the cost information from Exhibit 16-5 the average unit cost for the ABS value stream is $120 ($600,000/5,000).

CONTOH VALUE STREAM REPORTING Consider a plant of Allen Autoparts that produces only four products. Within this plant are two value streams : Aluminum wheels (Models A and B) and Steel Wheels (Model C and B). Exhibit 16-6 shows a profit and loss statement for the plant for the week of April 6.
DECISION MAKING BUY Revenue Material Costs Conversion Costs Value Stream Profit
MAKE $1,500,000 (410,000) (190,000) $ (900,000)
Revenue Material Costs Conversion Costs Value Stream Profit
$1,500,000 (380,000) (200,000) $ (920,000)

PERFORMANCE MEASUREMENT Sistem pengendalian lean menggunakan Box Scorecard yang membandingkan operational, capacity, dan faktor keuangan antara periode minggu sebelumnya dan melakukan perkiraan untuk periode minggu berikutnya

Life-Cycle Costing

Short Life Cycles Life-cycle planning yang baik sangat dibutuhkan, dan harga harus dipasang dengan secara tepat untuk menutupi segala biaya life-cycle costs dan mendapatkan return yang baik.

Balanced Scorecard: Basic Concepts LO - 4
Balanced scorecard menerjemahkan misi dan strategi organisasi ke dalam tujuan operasional dan ukuran kinerja untuk empat perspektif yang berbeda
Customer Perspective
1
2
Financial Perspective menggambarkan konsekuensi ekonomi dari tindakan yang diambil dalam tiga perspektif lainnya
3
mendefinisikan pelanggan dan segmen pasar di mana unit bisnis akan bersaing 4
Learning and Growth Perspective Mendefinisikan kapabilitas yang organisasi butuhkan untuk membuat pertumbuhan dan perbaikan dalam jangka panjang
BALANCED SCORECARD
Internal Business Process Perspective Menggambarkan proses internal yang dibutuhkan untuk menyediakan nilai untuk pelanggan dan pemilik
5
32
Strategy Translation menetapkan tujuan, ukuran, target, dan inisiatif untuk masing-masing perspektif
The Role of Performance Measures berasal dari visi, strategi, dan tujuan perusahaan
THE ROLE OF PERFORMANCE MEASURES
LAG VS LEAD
FINANCIAL VS NONFINANCIAL
OBJECTIVES VS SUBJECTIVES
EXTERNAL VS INTERNAL
MUST BE BALANCED LAG > HASIL PERHITUNGAN, PERHITUNGAN YANG DIHASILKAN DARI USAHA MASA LALU
LEAD > FAKTORFAKTOR YANG MEMACU UNTUK KINERJA MASA DEPAN
OBJECTIVES > DAPAT DENGAN MUDAH DIBACA(ANGKA) DAN DIVERIFIKASI
SUBJECTIVES > LEBIH SEDIKIT BENTUK ANGKANYA, BERSIFAT JUDGEMENTAL
MUST BE BALANCED
FINANCIAL > DITAMPILKAN DALAM BENTUK MATA UANG
EXTERNAL > BERHUBUNGAN DENGAN CUSTOMERS & SHAREHOLDERS
NONFINANCIAL > DITAMPILKAN DALAM BENTUK BUKAN MATA UANG
INTERNAL > BERHUBUNGAN DENGAN PROSES DAN KAPABILITAS YANG MENAMBAH NILAI UNTUK CUSTOMER & SHAREHOLDERS
Linking Performance Measure to Strategy
Outcome measure
Outcome measure is important because they reveal whether the strategy is being implemented successfully with the desired economic consequences.
39
Testable Strategy A set of linked objectives aimed at an overall goal. Dicapai dengan melihat hubungan sebab-akibat dari tujuan yang sudah ditetapkan.

The Four Perspective and Performance Measure
Financial Perspective
Customer Perspective
Customer Value. Difference between realization and sacrifice. •
Realization: yang diterima customer
•
Sacrifice: yang customer korbankan
Customer Perspective
Process Perspective

Increase Process Quality Untuk mengukur kualitas manufacturing cells dan value stream
FTT = (Total unit processed – Rejects and reworks)/Total Unit Processed) Cell FTT = FTT1 x FTT2 x FTT3
Kita melihat berapa presentase produk yang berkualitas

Cost untuk suatu value stream di bulan januari adalah sebesar $500,000. suatu value stream tersebut menghasilkan 2 model output yaitu model A dan B. Model A diproduksi sebanyak 25,000 units dan Model B diproduksi sebanyak 15,000 units. Tentukan unit cost nya?? JAWABAN : Unit cost = $500,000/(25,000+15,000) = $12.5
