Exectuve Summary

Major Product Stakeholder Analysis

We identified four major categories of stakeholders for our product. They are manufacturers, shipping & transportation companies, retailers, and consumers.

Stakeholder Objectives

• Manufacturers

   Low cost raw materials
   Simple manufacturing process required for materials chosen
   

Stakeholder Needs and Wants
Stakeholder	Needs	Wants
Consumer	Product should not require much force to hold/use (proper level of vibration, weight, etc.) Energy efficiency (and soap usage reduction) Customization (comfortable to use)	Maximize performance & minimize cost Lightweight and space efficient Ergonomic (material of handle part) Durability (especially of the sponge)
Retailer	Cheap & durable materials Lower electricity(batteries) use
Manufacturer	Cheap & easily processed materials Mass production Easy assembly	Volume-efficient materials
Shipping & Transportation	Lightweight Durability	Space-efficient packaging
