YAMAHA Kumamoto Products (YKP) – is a manufacturing sister company of YAMAHA Motorcycle – produces marine engines and supply them to 180 countries.

Even through their products are supplied to the distribution chain, YKP run under the MTO mode ofoperation and made the master production schedule driven by assembly.

Parts production had severe problems – lack of capacity and mis-synchronization with subcontractors.

For solving these problems, YKP started Pilot implementation of MTIA – Make to Internal Availability – in February 2013. After 2-3 months, YKP saw that production lead time was reduced significantly

while increasing productivity. Management decided to move to the full execution.

Since then, YKP developed their own IT tool for MTIA and started the preparation for expanding theimplementation to the distribution.

Features of this presentation:

• Bottom-up implementation 

• Transform from MTO to MTA

• Win-Win relationship with subcontractors 

• Usage of Thinking Processes before and during implementation

Top’s dream::::“  To become a true “Coherent plant” based on link management technique ”  

SCM slogan::::Synchronize Production and Sales by integrating physical process flow, information flowand managerial flow

Increase Efficiency

Reduce Inventory

By reducing LT, we will achieve:

⇒ OE reduced

⇒Demand satisfied

Coherent Plant 

= == = Nimble & Strong Chain Can “TOC” solvethese issues?

“Stabilized” & “Rapid”

Flow

Implementing APS…Backward schedulingBut Murphy in execution

Same Demands?We have focused on higher DDP for HQ

But the need of customer in US issame as in Indonesia?

What is “Coherent Plant”?Can we change the way of

Part Production?

Inventory is“Enemy”?

What’s wrong with inventory?

• There are stocks hold after machiningprocesses.

• If we have a warehouse, there is no needto take “order quantity” into accountwhen determining “production quantity”(Decoupled)

 “Reality”

• We had seen the area holding stocks as just astopping point (yard), not a warehouse.

• There is no way (no idea) to give instructions for

which SKU, how may and when to produce.

• Quantity and release date of WOs areplanned per each work center according to

master schedule of assembly – it meansthey are run under MTO having due datesfor assembly.

• Due dates are set per each work center.

WO – Work Order

WHAT to Change?

Stock area in front of assembly is

not Warehouse, but Yard.

Reducing inventory at any place is

a major consideration

Produce to Assembly Schedule. WO quantity is influenced by

assembly schedule

Fixed Schedule. Production plan is made fortnightly

Every process has local due date

Establishing SFWH as Regulator

of Replenishment System. Build Stock Buffer and commit to

availability at SFWH

Replenish to Consumption.

Determine WO quantity with

consideration of difference in

capacity from assembly

Flexible Schedule throughBuffer Management.

Frequently plan when to release

WO according to buffer status

Supply to SFWH – No Push

Produced stock is ”Pushed” to downstream

Stock after machining is treated as

WIP

Manage stock per process

Focus on reducing inventory

(Inventories are all Enemy)

Stock after machining is strategically

treated as on-hand stock at SFWH

① Explain future vision and business needs(to secure Japanese production way by

“coherent plant”)

② Explain MTIA by our own words

(Stock Buffer, Replenishment, Priority)

As the result that:

The GM approved to add capacity temporarily to build stock buffer without hesitation.

YKP puts pressure to reduce lead time,But in reality, there are many shortages 

Too many reworks due to casting’s defective 

eating our capacity We don’t understand 

what is “coherent plant” 

Offering our solution (MTIA)Interview with GM

To understand the image of the new way 

Listened to the subcontractors’ voice to understand their reality

GM’s comments:

• I understood that the MTIA could help us.

• We didn’t see any significant risk because of the careful approach by the pilot instead of full execution

• MTIA has a robust mechanism so that we are all aligned through synchronized tool & measurements

Seek for Collaoration with

Sucontractor!

① 『With my own words』

② 『Resistance? – Welcome!』』』』

③ 『My mind is sending』

④ 『Focus』

⑤ 『TOC Full-kit』

It makes no sense to speak aloud the material provided by consultants.

Understanding the logic of solution and gaining confidence gives people security.

Resistance to change is the first step to achieving goal. We should investigatethe reason behind their response and prove into the identity of the fear.

If I tell the objective/reason with the mind of respect, then people will accept.

I realized the power of TOC through experiencing not only replenishment solutionbut also MT and CCPM. I am excited to expand the implementation – DTA fordistribution and CCPM for engineering. I believe that TOC Full-kit will guide my

company to the right direction.

The key success factor is focusing instead of trying to do too much.
