The Choke products is also one of Schaffners’ revenue generators. Presentation title DD.MM.YYYY Applying knowledge management tools to solve a company problem in Schaffner. Figure 1.0 shows the Choke products which are the traditional strong hold products of Schaffner. At the peak, a few years ago Schaffner produces between 1 million to 1.5 millions a year. The Choke products is also one of Schaffners’ revenue generators. In the year 2008 Schaffner sold slightly above half a million pieces and 2009 , Schaffner sold much less than half a million pieces.

Presentation title DD.MM.YYYY Applying knowledge management tools to solve a company problem in Schaffner. The main problem is ; Schaffner is losing market share and is being threatened that the entire Choke business will be wiped out within two to three years.

Schaffner’s prices are above the competitors Presentation title DD.MM.YYYY Problem; Schaffner is losing market share and is being threatened that the entire Choke business will be wiped out within two to three years. Schaffner’s prices are above the competitors No priority for salesmen to sell Not designing to customers’ requirements 3% >40% >5% Losing market share on Choke products >44% >5% Schaffners’ Chokes have lesser performance features than competitors Unhappy customers >3% Customers shifting to new technology platform Fig. 2.0

Presentation title DD.MM.YYYY Reorganise the work flow from traditional production conveyor lines to lean cell concepts. By applying Lean cell concepts , the following causes/ actions will be taken care of; Fig.2.1 Cause #1 Cause #3 Cause #7 Cause #8 Cause #9 Cause #10. Fig.2.2 Cause #4. Cause #5 Cause #6.

Application of LEAN CELL CONCEPTS Presentation title DD.MM.YYYY Application of LEAN CELL CONCEPTS First , the entire process is mapped out as shown in fig.2.3. All the processes are studied by removing the 7 wastes in manufacturing. Figures 3.0 A to 3.0D show the application of lean cell concepts. Fig. E is the final lean cell layout. The lean cell concepts will reorganise all the process stations close together with the objective of a smooth and ergonomic flow. One piece flow is applied. Materials are at the point of use. It is a two bin system .

Value Adding Processes DD.MM.YYYY Presentation title DD.MM.YYYY Value Adding Processes Smooth cellular flow by connecting the relevant processes together: Operation 1 Customer Raw Material Operation 2 Operation 3 Operation 4 Operation 5 Continued from previous Motion Motion is a waste   Picking up a part is different than going to pick up a part Use natural limited motion Use physics Gravity Ergonomics Product defects Obvious waste of cost of product Opportunity cost of resources spent to make the defect Loss of customer satisfaction/business Internal defect Not using the talent, knowledge and experience of all people is waste Fig.3.0D One Piece Flow Production in a Cellular Layout: Significantly reduces transportation, inventory, and waiting time while improving quality, delivery, and costs.

Use Nonaka model for automating the following process operations; Presentation title DD.MM.YYYY Problem; Schaffner is losing market share and is being threatened that the entire Choke business will be wiped out within two to three years By automating the process operations the following causes / actions will be solved. Fig 2.2 Cause # 2 Cause #11 Fig. 2.2 Cause # 2. Use Nonaka model for automating the following process operations; Winding process. Cutting and wave dipping process. Pin- insertion process. Assembly process. Moulding process. This will cut cycle time by at least 35% but most important is the quality improvements ( yield and less scrap).

SUPPLIER MANAGEMENT PLAN( SMP) Presentation title DD.MM.YYYY SUPPLIER MANAGEMENT PLAN( SMP) SMP By localisation of European parts. Manage suppliers by developing merit points ; Quality------------ 50 points. Cost……………..20 points. Delivery…………30 points. On- time delivery targets are jointly set with suppliers. Develop local suppliers that have materials that are less expensive than European materials. This can be achieved by changing the specification of materials with R&D. The above actions will reduce materials costs by 18%.

Figures 7.0 A and 7.0 B show how the target is achieved. Presentation title DD.MM.YYYY The final picture. Figures 7.0 A and 7.0 B show how the target is achieved.
