INTRODUCTION
The CAX Cable project was initiated by BTS Tech in order to develop a new coaxial cable
product capable of delivering high-definition picture and sound quality for residential use. This
project includes the development of the cable product as well as the manufacturing process
required to produce the product. The CAX Cable process improvement plan describes how the
manufacturing processes will be analyzed in order to continually monitor and improve
production efforts. The process improvement plan will be followed iteratively throughout the
project’s lifecycle and includes all processes involved with the manufacturing of the CAX Cable.
The process improvement plan lays out the necessary steps to identify, measure, and implement
the necessary process improvements for the CAX Cable product.
PROCESS BOUNDARIES
The CAX Cable Project consists of two processes which comprise the overall manufacturing
process: cable stranding and cable jacketing. Cable stranding consists of the stranding of the
internal metallic cable element with protective Kevlar fibers in order to improve cable tensile
strength. Cable jacketing consists of jacketing the stranded core with an extruded polyethylene
cover in order to protect the internal cable structure from environmental effects and ensure the
transmission of data signals. As part of the process improvement plan the stranding and
jacketing process boundaries have been established below:
Stranding:
Start – the stranding process starts immediately upon an order being placed for
material from the operations manager
Completion – the stranding process is complete once the stranded core (of pre-
determined length) has been built and spooled on a cable reel and moved to the
holding area
Inputs – the inputs for the stranding process are: core length (based on order),
materials, written work order, and user defined inputs on the stranding machine
Outputs – the outputs for the stranding process are: a stranded core on a cable reel (of
pre-determined length), and an acknowledged work authorization from the stranding
machine technician
Data Required – the data required for the stranding process is: total cable length,
finished cable diameter, and core material types
Process Owner – the stranding process owner is J. Green, Senior Process Technology
Engineer
Jacketing:
Start – the jacketing process starts immediately upon receipt of a stranded cable core
from the receiving area.

Completion – the jacketing process is complete once the stranded core is jacketed,
spooled on a cable reel, and sent to the finished cable holding area
Inputs – the inputs for the jacketing process are: a stranded cable core and an
acknowledged work authorization from the stranding machine technician (which
includes all jacketing material specifications)
Outputs – the outputs of the jacketing process are: a jacketed (completed) CAX Cable
with a specification chart and acknowledged work authorization from the jacketing
line technician
Data Required – the data required for the jacketing process is: extrusion temperature,
cooling trough temperature, material specifications, total cable length, finished cable
diameter, and jacket print specifications
Process Owner – the jacketing process owner is B. White, Process Technology
Engineer
PROCESS CONFIGURATION
BTS Tech has modeled its initial CAX Cable manufacturing processes on existing processes
currently is use for other cable products and families. The process improvement plan for this
project provides BTS Tech with an opportunity to analyze and improve the cable manufacturing
process for CAX Cable which, ultimately, may result in process improvements for all BTS Tech
cable products. The project team will utilize the stranding and jacketing process configurations,
in conjunction with process metrics, to conduct process analyses, determine potential areas for
improvement, and implement improvement measures. To do this, the team will follow the
processes as planned during initial cable runs in order to verify process boundaries and gather
metrics. As the team identifies potential process areas of improvement, adjustments will be
made and the modified process will be run to validate the process and to gather additional
metrics for comparison.

Jacketing Process Configuration:
PROCESS METRICS
Process metrics and control limits will be used, in conjunction with process configuration, to
guide the process improvement efforts for the CAX Cable project. Since the stranding and
jacketing processes for CAX Cable are based on the processes for other cable families, the
metrics, acceptable values, and control limits are known. However, as part of the CAX Cable
process improvement plan, the project team will iteratively analyze the process configurations,
metrics, and measured values in order to implement a cycle of continuous improvement. The
existing metrics, values, and control limits are based on industry-wide customer requirements for
cost and performance.

Measurements for each metric will be taken for every iteration of a stranding and jacketing for a
trial CAX Cable. These measurements will be plotted on a control chart in order to ensure that
process parameters fall within the acceptable range. As the process is validated for this new
product and the values normalize, the project team will use the metrics and process
configurations to determine areas within the processes where improvements can be made. As
adjustments to the processes are made, the team will continue to track the metrics in order to
validate any improvements to the process and for updates or changes to project documentation.
TARGETS FOR IMPROVED PERFORMANCE
The CAX Cable project team has developed targets for improved performance in each of the
metrics for both the stranding and jacketing processes. These metrics are based on existing BTS
Tech metrics for all other cable products and families. However, this project provides an
opportunity to improve these processes which may potentially result in significant savings for
cost and time for CAX Cable as well as all other BTS Tech cable products. The charts below
provide the CAX Cable stranding and jacketing process metrics with both the current values and
target values.

Based on current capacity of BTS Tech cable products, the targeted stranding and jacketing
waste reductions will result in over $550,000 in material savings annually. The stranding and
jacketing process time targets will allow the operations group to increase throughput and achieve
significant increases in scheduling flexibility which will allow BTS Tech to better meet its
customer requirements.
