Which statement about ergonomics is true?

The statement indicating that a workstation may be ergonomic for one assembler and uncomfortable for another is accurate because ergonomics takes into account the individual differences in body size, strength, flexibility, and comfort among workers. Each person may have unique needs based on their physical characteristics and the specific tasks they perform. This highlights the importance of customizing workstations to fit the individual, ensuring that they promote comfort and efficiency.

In contrast, ergonomics is not universally effective for all workers doing various tasks, as this approach requires customization to be truly effective. Implementation of ergonomic principles does not guarantee increased productivity without costs; often, there are investments in equipment or changes needed in the workplace. Additionally, ergonomics explicitly accounts for individual differences, focusing on how to make work environments more suitable for diverse workers rather than ignoring these differences. This comprehensive understanding illustrates why the correct statement reflects the nuanced nature of ergonomics in the workplace.
