Certified Production & Operations Manager (POM) Practice Exam

Which of the following statements about CAD is not true?

1. Some systems permit engineering or cost analysis of proposed designs

2. It increases the productivity of designers

3. It requires a good database

4. It is used successfully by all manufacturing companies

The correct answer is: It is used successfully by all manufacturing companies

The statement that CAD is used successfully by all manufacturing companies is not true because not all companies, particularly smaller ones or those in certain industries, may have the resources or need for advanced CAD systems. While CAD has become a standard tool in many sectors due to its benefits in design efficiency, visualization, and modifications, some manufacturing companies may rely on traditional methods or have limited application of CAD technology due to financial constraints, lack of skilled personnel, or the specific nature of their products that may not necessitate complex design systems. In contrast, the other statements accurately reflect common characteristics of CAD systems. Many CAD tools indeed allow for engineering analysis and cost estimation, enhancing the designer's ability to optimize designs before production. Productivity is greatly increased as designers can work faster and more accurately with CAD software compared to traditional drafting methods. Additionally, a robust database is typically essential for CAD systems to store and manage design data effectively, facilitating access and collaboration.
