Clarke Gear Co. Uses Lean Manufacturing principles such as
 "The Closed Mitt Rule" to achieve high quality & productivity.

The Closed Mitt Rule

C

The waste of
COMPLEXITY

Find simple solutions in place of complex ones.  Complex solutions tend to produce more waste and are harder to manage.

L

The waste of
LABOR
Eliminate all unnecessary "movement" and steps of people.

O

The waste of
OVER PRODUCTION

Produce only the amount of goods the customer wants when the customer wants them.  Eliminate any product beyond customer demand.

S

The waste of
SPACE

Conserve space in plant and office by improving poor arrangement of machines, people, workstations, storage of excess raw materials, parts working-in-process and finished inventories.

E

The waste of
ENERGY

Operate equipment and use person-power only for productive purposes.  Avoid false scale efficiencies, excess power utilization and unproductive operations.

D

The waste of
DEFECTS
Strive to achieve the goal of no rework ever....no mistakes, rework or defects.

M

The waste of
MATERIALS
Convert all material into products; avoid scrap, trim excess or bad raw materials.

I

The waste of 
IDLE MATERIALS

Make sure nothing sits so there is a steady flow to the customer.  Any kind of idle inventory represents waste including raw materials in any form, information, work-in-process inventories and finished goods.

T

The waste of 
TIME

Eliminate days, long setups and unplanned downtime of machines, process and people.  These often result from poor specifications, missing parts or information, late deliveries and inadequate training.

T

The waste of
TRANSPORTATION

Eliminate the movement of materials or information that does not add value to the product, such as double and triple handling of goods and needless movement of information.
