If your colleague ignores industry standards in design, it can lead to significant costs for the project. Standards ensure quality, safety, and manufacturability. Ignoring them can cause issues like incompatibility with manufacturing processes, requiring costly adjustments. It may also lead to safety and quality problems, which require expensive revisions. Additionally, failure to follow standards can cause legal issues or prevent necessary certifications. Overall, ignoring standards increases time, resources, and costs, while affecting product quality. It’s crucial for your colleague to respect standards to keep the project on track and within budget.
