The Design Process In Operations Management
What will we understand from design and process?
Design: ”To design” refers to the process of originating and
developing a plan for a product, service or process.
Process: It is any part of an organization which takes a set of
input resources which are then used to transform something into
outputs of products or services.

It is the beginning of the design process. The design process
begins with understanding the customer and identifying customer
needs.
Marketing research, suppliers, salespersons in the field, factory
workers, new technological developments, company’s own research

3. Reverse Engineering:
It is carefully dismantling a competitor’s product to improve
your own product.
For example:
Ford used this approach successfully in its design of the Taurus
automobile, assessing 400 features of competitors’ products and
copying, adapting, or enhancing more than 300 of them, including
Audi’s accelerator pedal, Toyota’s fuel-gauge accuracy, and BMW’s
tire and jack storage.

The Three Types of Concurrent Designs
1. Form Design:
Form design refers to the physical appearance of a product. In
other words, how the product will look.
2. Functional Design:
It is concerned with how the product performs. Three
performance characteristics considered during this phase of design
are reliability, maintainability, and usability.
