1. THE PROBLEM SOLVING METHOD
AN ENGINEERING APPROACH TO
DESIGN

2. PHASE 1 Recognition of Need
Identify the Problem

3. PHASE 2 The Feasibility Study
Define the Problem- all elements
Identify all the design requirements
Identify the factors or restrictions -limits
consider possible consequences of the design
generate alternative solutions

4. PHASE 3 Preliminary Design
Select the best solution(s) as they now appear
Consider all the parts, components, materials, processes, methods, strengths, and dimensions for each of the possible design solutions
Consider the availability of materials, components, labor, building, land, and finances
Determine the impact of each design solution on society and on the natural environment
Model, analyze, and test each candidate design as necessary
Evaluate and compare candidate design as objectively as possible

5. PHASE 4 Detailed Design Examine all principal requirements
consider any abnormal situations
Refine models and analyze them
Test for strength, endurance, and life and correlate test results
Specify the design in detail, coordinate the details with those involved in production, construction, and marketing
Record the design details in reports, drawings, graphs, and charts
IF THE DESIGN SOLUTION IS SATISFACTORY GO TO PHASE 5. IF NOT START OVER OR GIVE UP!

6. PHASE 5 Implementation RECYCLE
Identify the materials, personnel, processes, methods, marketing, financing and facilities that are required
Produce or construct the design in an optimum manor
Market the product or sell the system
Monitor the success of the product or system and make design modifications as necessary
Recover resources as necessary. In other words
RECYCLE

7. GREAT!!! STICK WITH IT, OTHERWISE…IF
IF THE DESIGN IS PROFITABLE
IF PRODUCTION IS GOING WELL
IF MARKETING IS BOOMING
GREAT!!! STICK WITH IT, OTHERWISE…
Modify , redesign, or abandon the design
