Process Management & Innovation
P05
Definition
A matrix diagram, also known as a Quality function
deployment (QFD), is one of the Seven Management
Tools that is used for identifying inter-relationships of
the process or product variable that must be managed
in the company’s plan .
It is a grid by which you can used to analysis your
materials to make comparison, selection or choice as it
systemically organize a variety of data related to a
process or product improvements.
Purposes
The application of the Matrix Diagram is to




Assigned task to complete a project
Make a comparison between completing alternatives that
involves a variety of characteristics
Prioritize combination of new and old activities that
maximized the number of total objectives met.
Establish the relationship between the customer
requirements and product features, where a number of
product features may be combined to deliver the
required customer benefit.

Case Study (An example)
My parents work in an environmental chemistry laboratory
and they want to assign their employees to several tasks.
Their goal is to rid the confusion with distributing tasks to
be done. The problem with their organization is to
work is not distributed properly. One job had multiple
employees, while another job was neglected. My dad will
develop an L-shaped matrix diagram to organize and solve
the current problem.
