WHAT IS PRODUCT

DEVELOPMENT?

Product development is the process of designing,creating, and marketing an idea or product.

The product can either be one that is new to themarketplace or one that is new to your particularcompany, or, an existing product that has beenimproved.

The product development involves much morethan the design

To make profits for share holders

Phase iiiPhase iii

Functions of the product are examined by division ofthe product into various subsystems.

Alternative ways for the arrangement of subsystemsare identified and studied. Phase 3 is also called embodiment design. Selections are made for material and manufacturing

processes and dimensions of the parts areestablished.

Ergonomics and styling to the product were made. Critical parts are built with rapid prototyping methods

and tested physically

Phase v

Alpha prototypes were made and tested

Beta tests are made and tested by the selected

customers in their own environment. During this phase the marketing people work on the

promotional material for the product launch.

Sales force puts the finishing touches on sales plan.

Finally a major review is carried out to determinewhether the work has been done in quality way

Phase vi

Manufacturing operation begins to make and assemble theproduct using the intended production system.

Public announcements and the advertisements werereleased before the product is released into the market.

After 6-12 months of the product release a major review isconducted.

Latest financial information on sales, costs, profits,development costs and time to launch will be reviewed.

The strengths and weakness during the PDP wereidentified.

Brakes (bicycle)

The function of brakes is to stop or slow downwhen moving or to prevent it from moving

when it is stationary.

The bicycle brakes are various types they are

1. Spoon brakes.

2. Rim brakes.

The rim brakes are also of different types.
