Differences Between Product and Service Design


Product design is more important than ever because customers are demanding greater product variety and are switching more quickly to products with state-of-the-art technology. The impacts of greater product variety and shorter product life cycles have a multiplicative effect on the number of new products and derivative products that need to be designed.

Firms are recognizing that the concept behind design for manufacturing can also be extended beyond cost control to design products that are easy to service and maintain.

Improving manufacturability is an important goal for product design. It can be a powerful tool to improve product quality and lower manufacturing cost.CONTENTS

Major factors in strategy
-Time –to- market
-Customer satisfaction
-Competitive advantage

Increased emphasis on or attention to:
-Customer satisfaction
-Reducing time to introduce new product or service
-Reducing time to produce product
-The organization’s capabilities to produce or deliver the item -Environmental concerns
-Designing products & services that are “ user friendly” -Designing products that use less material

Translate customer wants and needs into product and service requirements •Refine existing products and services
Develop new products and services
Formulate quality goals
Formulate cost targets
Construct and test prototypes
Document specifications

Be competitive
Increase business growth & profits
Avoid downsizing with development of new products
Improve product quality
Achieve cost reductions in labor or materials
Development time and cost
Resulting product or service quality
Capability to produce or deliver a given product or service

Taking into account the capabilities of the organization in designing goods and services

-Marketing department
-R&D department

-Customers (QFD)

Begins with motivation for design
To achieve goals of the organization
Ultimately, customer is the driving force
Must have ideas for new or improved designs

-Voice of the customer
-House of quality
QFD: An approach that integrates the “voice of the customer” into the product and service development process.

Reverse engineering is the dismantling and inspecting of a competitor’s product to discover product improvements.

Beyond the overall objective to achieve customer satisfaction while making a reasonable profit is: Design for Manufacturing (DFM)
The designers’ consideration of the organization’s manufacturing capabilities when designing product. The more general term design for operations encompasses services as well as manufacturing

Manufacturability is the ease of fabrication and /or assembly which is important for: -Cost

-Product Liability
-Uniform commercial code

-Releasing products with defects


Product liability – A manufacturer is liable for any injuries or damages...
