Step 1

Recognizing the need for a product or a service

Step 2

Problem definition and understanding

  • This is the most important step in any design process
    ▪ Before you move on to the next step
                    o Make sure you understand the problem
                    o Make sure that the problem is well defined
    ▪ Good problem solvers are those who first fully understand what the problem is.

Step 3

Research and Preparation

  • Collect useful information
                  o Search to determine if a product already exists
                  o Perhaps you could adopt or modify existing components
                  o Review and organize the information collected in a suitable manner.

Step 4

Conceptualization

  • Generate ideas or concepts that could offer reasonable solutions to your problem.

Step 5

Synthesis

  • At this point you begin to consider details.

  •  Perform calculations, run computer models, narrow down the type of materials to be used, size the components of the system, and answer questions about how the product is going to be fabricated.

  • Consult pertinent codes and standards for compliance.

Step 6

Evaluation

  • Analyze the problem in more detail.

  • Identify critical design parameters and consider their influence in your final design.

  •  Make sure that all calculations are performed correctly.

  •  Best solution must be identified from alternatives.

  •  Details of design must be worked out fully.

Step 7

Optimization

  • Optimization is based on some particular criterion such as cost, strength, size, weight, reliability, noise, or performance.

  • Optimizing individual components of an engineering system does not necessarily lead to an optimized system.

Step 8

Presentation

  • You need to communicate your solution to the client, who may be your boss, another group within your company, or an outside customer.

  • Engineers are required to give oral and progress reports on regular basis to various groups,
    consequently presentation could well be an integral part of many other design steps.
