Executive Summary

Major Stakeholders and Their Needs

Four major stakeholders were identified in the life cycle of the umbrella: the consumer, the retailer, the manufacturer and the distributor. Each of them is described in detail in the following subsections.

Consumer

An umbrella is a product commonly used by people to refuge from rain and other environmental phenomena. Most people have had at least one umbrella in their lifetime, therefore consumer diversity was considered during the evaluation of their needs. The requirements of the consumer can be summarized as:

   Rigidity: the product needs to be able to support itself in the hands of the person using it.

   Portability:  consumers want a product that they can carry around all day, they need a product that is compact and easy to carry.

   Appearance: the products should appeal the consumer.

   Low cost:  as a product that users carry all day, umbrellas tend to be lost or forgotten often. A low cost device could be replaced more often, than an expensive one.  In addition, many consumers would not want to spend a large amount of money in a commonly used object.

   Safety: umbrellas have many small components and outstanding elements, they need to be safe for people to use.

   Durability: consumers want a product that does not need replacement often

   Light-weight: commonly, consumers carry umbrellas all day with them, most would opt not to carry or use it if it is too heavy.

Product History

Product Functionality and Use

To open the umbrella, the user presses the button on the handle and allows it to extend and then expand fully. Then he or she holds the umbrella over her or his head, so as to prevent the elements from reaching her or him. To close the umbrella, the user pulls the rider down until it is locked back into the handle.
