Project Management Office
Charter
Quality Improvement Team in the production of shoe uppers, Sewing Line- 1
I. Establishment
The purpose of this charter is to establish a Quality Improvement Team to reduce the high level of rejections of shoe uppers in the Sewing Line 1 of Apex Footwear Ltd,. and to find sustainable quality improvement ways
The Team will be led by Mahtab Siddiqui, General Manager of the company.
The team is charged with analyzing current level of rejections, identifying causes of rejections of shoe uppers, developing control measures to reduce rejections and implementing improvement measures to ensure that rejection levels remain at industry average(benchmark) or above it.
II. Background
Apex Footwear Ltd. was established in 1990 with the technical support from Ciurli, Italy to produce 4000 pairs of leather shoes purely for the export markets such as the Italy, Germany, UK, and Japan.
It comprised of four production lines each with a capacity to produce 1000 pairs of leather shoes per day.
Each production line consists of three process lines which are as follows :
Process Line Main Activities Output
Cutting Line Cutting Leather into different Cut Components components of shoes
Sewing Line Sewing Cut Components Shoe Uppers
Lasting Line Lasting shoes as per their Finished shoes Last (forma) sizes
All the process lines operate in a conveyor system.
But the company has a very high level of rejection rates in each process line.
Specially, in the sewing lines the rate of rejection of finished uppers is almost 6% in addition to rejections in different stages of upper production. Taken all stages and finished uppers, the effective rate of rejection was 12%. On top of that there are also wastages of resources with respect to repair works.
On January 2, 2009 the Managing Director of the company issued the following task to the General Manager:
“ Identify the causes for rejections of 12% of shoe uppers in the Sewing Line – 1 and find ways to reduce it to the industry average of 1% and recommend ways to sustain and improve the newly developed techniques and to replicate them in other Sewing Lines.”
III. The scope
The scope of this project will be confined to development of procedures that will reduce the rate of rejections in the sewing line -1 and application of those procedures as guidelines for replication of successes in other sewing lines and across the factory.
To kick-off the this project the activities described in the following table will be followed:

Current Problem :
The company has average rejection rate of 12% of shoe uppers in its sewing lines. It produces 2000 pairs of shoe uppers per day and has a total rejection of 240 pairs of uppers per day. However the total count of rejected uppers is poorly defined in terms of full uppers and different components estimated to constitute a full upper.
Purpose of Project :
This project would identify root causes behind the rejection of shoe uppers and will implement solution to fix the problem. The target is to reduce the level of rejection to the industry average of 1%.
Business case :
Critical business decision regarding acceptance of a new long term order from an Italian customer depends upon reliable and accurate achievement of the project goal. Currently the company exports 2000 pairs of shoes to Italy and Germany. It is currently negotiating with an Italian company to export another 1000 pairs per day. But the profit margin with the Italian company is so tight that with 12% rejection rates it would not be possible for the company to accept the order.
The main benefit with respect to the successful implementation of this project will be to produce as per the customer requirement both in terms of quality and quantity.
Goal/Metrics
Design and development of a complete set of solutions to address the root causes behind such a high rate of rejection. This involves two data streams ; rejection at complete upper and rejection as components at different stages. Determination of causes behind rejection as complete uppers and determination of causes behind rejection as components.
Identify the bottlenecks in the sewing process. Determine the root causes behind the formation of the bottlenecks or constraints.
Determine the full extent of the problem through data analysis, focus group, brain storming, interviews and other tests.
Develop solutions for improving the processes and monitor the results of the implemented solutions.
