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:
Retailer
Manufacturer
Distributor
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.
