5 ECE Department asses needs analyze design requirements design system The problem statement has the following attributes: relatively nontechnical language of the customer straightforward Assess Needs (Problem Statement-1)

6 ECE Department Techniques for arriving at a problem statement: 1.question the customer 2.differentiate needs and wants 3.explore project boundaries 4.input/output analysis 5.preview the user interface 6.survey design attributes 7.identify conflicting needs 8.prepare a draft operations manual Assess Needs (Problem Statement -2) asses needs analyze design requirements design system

7 ECE Department asses needs analyze design requirements design system Assess Needs (Problem Statement-3) Sections of the problem statement: 1.background 2.the design 3.deliverables of the design project

8 ECE Department Problem Statement Example: Paste and Place Students with severe disabilities face many challenges with tasks that we perform every day with little thought. For one student in the “Life Skills” program in West Springfield schools, his limited fine motor skills make it impossible for him to squeeze tooth paste onto his tooth brush. Our “Paste and Place” system will offer him independence by allowing him to brush his teeth without assistance. An easy-loading system will secure the toothbrush, move it under the toothpaste, squeeze the toothpaste, and present the toothbrush for use. asses needs analyze design requirements design system

9 ECE Department asses needs analyze design requirements design system Analyze Design Requirements (Requirement Specs - 1) The requirement specifications can be thought of as a technical version of the problem statement. It should not propose a solution.
