Over-engineering happens when engineers design products with unnecessary features. When project requirements are unclear or there is uncertainty about product performance, over-engineering is likely to occur.
To avoid these engineering mistakes, requirement transparency and early simulation are key solutions. PLM tools that manage requirements can help mechanical engineers design with the right features in mind. Additionally, simulating designs early and often shows engineers how their product is functioning so they can determine if features are too robust or too sparse.
Signs of over-engineering aren’t always obvious, but it’s important to recognize them to save time and reduce costs. Designs that exceed requirements with unrequired strength, perform in extreme and unrealistic conditions, or reinventions of existing designs are just a few symptoms of over-engineering.
