  40. Production Control Operating Procedures • Prepare a batch of 4 units. • Cut each sheet (one at a time) into two: roof and base. • Write the batch number on the roof and the base. All items in the same batch have the same number. The numbers have to match in assembly. • Repeat • 4 times, which yields one batch • When 4 units (one batch) are complete, “release” the batch. • Put the batch in your out-basket: it’s ready for pickup by the trucker. • Record release time for each batch. • Release one batch each minute.

  41. Truckers Operating Procedures • Truckers are responsible for transporting work in process inventory between production steps. • You can carry only one batch of 4 roofs or 4 bases at a time. Not both! Production Control (color sheets, log sheets, scissors) Base Punch (scissors) Roof Base Form (scissors) (scissors) Base Weld (stapler) Final Assembly (tape) Quality Control Customer

  47. Check each batch if they conform to quality standards! If the house conforms to quality standards, put it on the market. Once on the market no more rework! Customers can reject houses Quality Standards Batch numbers must match. Folds and cuts should be along appropriate lines. Folds should be crisp and cuts should be straight. Roof should be centered and door should be visible. Top of base should be flush with roof. Staples and tape should be centered and parallel to the ground. Not too much tape. About 1 cm Staples about 0.5 cm from edge. Quality Assurance Operating Procedures
