3 Why write a problem statement?
Prototypes Engineering Design and Development Lesson 4.1 Plan for the Prototype Why write a problem statement? Research and Exploration Design and Construction Testing, Documentation, and Presentation Problem Selection Design Specification Testing Criteria & Method Topic Background Decision Matrix Testing Procedure Problem Statement Concept Testing Physical Testing Statement of Purpose Design Proposal Record Data Cited Validation Gantt Chart (timeline) Critical Design Review Cited Justification Sketching Refinement Redesign and Refine Past & Present Solutions Technical Drawing Re-test Market Research Material List Determine Conclusion Problem Proposal Cost Multimedia Display Tool Selection Web Page Tool Safety Research Paper Mock Up & Modeling Electronic Portfolio Prototype Construction Problem Statement The first step in every technical problem-solving endeavor is to identify the need or problem. [click] But before you can solve the problem, you need to know exactly what the problem is. [click] A well-written problem statement allows you to focus your effort and provides a measure against which to measure the success of the design. Focus effort Provide a measure of success

4 What Makes a Good Problem Statement?
Writing a Problem Statement Engineering Design and Development Unit 2 – Lesson 2.1 – Identify a Valid Problem What Makes a Good Problem Statement? Concise Leaves room for multiple solutions Does not imply a solution Specific enough to be solvable in the given time frame and with available resources Answers the questions: Who has the problem? What exactly is the problem? Where does the problem exist? When has it happened and for how long? How prevalent is the problem (statistics)? Is the problem valid? (Who says there is a problem?) In order to be useful, the problem statement must have the following characteristics. [Read through the bullet list]. Finally, in order for the solution to be valuable, the problem must be valid. That is, you should be able to find reliable sources that also identifies the need for a solution to the problem.

5 Problem Statement Example 1
Writing a Problem Statement Engineering Design and Development Unit 2 – Lesson 2.1 – Identify a Valid Problem Problem Statement Example 1 Lots of people go fishing for red fish and do not catch anything. There aren’t as many red fish as there used to be. Game fishermen fishing in the lower Laguna Madre of Texas reported between a decrease of 20% in red drum (i.e., sciaenops ocellatus). This loss can be attributed to premature death due to mouth infections caused when undersized fish are caught and released. Here is an example of a statement that expresses a general problem. However, this isn’t a good problem statement. [click] However, if we add some more information and answer the Who, What, Where, When and How Many questions, we can create a good problem statement. [Click through the questions] Who? What? Where? When? How Many?

6 Problem Statement Example 2
Writing a Problem Statement Engineering Design and Development Unit 2 – Lesson 2.1 – Identify a Valid Problem Problem Statement Example 2 Car accidents are occurring because the intersection needs to be redesigned. What are some issues with this problem statement? Only cars or all vehicles? Are vehicles hitting vehicles? Other objects? Pedestrians? What is the current design of the intersection? Does the intersection really need to be redesigned, or could the solution involve the lights, speed limits, lane configurations, traffic violation enforcement, etc.? . [Ask students to write a good problem statement for this problem.] [click] Answers to these questions may help you write a good problem statement. Revise the problem statement
