Line Balancing – Before

Student Name

Instructions:

Look at the existing production process below before line balancing. You can see that Operation (OP)5 and OP9 are exceeding the Takt time dictated by the customer because they are taller than the green dotted line.

You can also see that there is some unused green space representing non-utilized resources waste between parts being processed at each station. E.g., Station 1 has 20 seconds of downtime between parts.

There are also 16 stations being used, which means there are 15 instances of transportation waste moving parts from one station to the next.

Proceed to the next slide to complete the line balancing activity.

Line Balancing - After

Student Name

Instructions:

Your improvement project team has already reduced the total cycle time (TCT) per unit for OP5 by splitting it up so that it is being run on 2 machines at once.

The team has also reduced the TCT for OP9 by splitting it up so that it is being done by 2 people at once. The blocks for OP5 and OP9 have been duplicated and resized accordingly. This means that all operations are now within the Takt time.

Your team still needs to reduce non-utilized resources waste and transportation waste. Reducing the amount of green space leftover will reduce non-utilized resources waste. Reducing the number of stations being used will reduce transportation waste. Rearrange the blocks on the right to fit inside the green rectangle below. Operations must be shown in order, but you can stack them vertically in order from bottom to top as needed. Do not resize any blocks. All blue blocks must be used.
