內容簡介
By reading this book thoroughly:
1. You can rectify incorrect concepts as early as possible; after all, if you do it right in the first place, you will always get it right.
2. You will significantly reduce the number of times of modification, the time for repeated design modifications, as well as production and tooling modification costs.
3. You, as an inexperienced designer, can enhance your own skills without solely relying on experienced ones guidance.
4. You, as an experienced designer, will be enlightened at the right time to integrate your own design experience without wasting time on repetitive trials and errors.
5. You, as a design supervisor, can adopt this book as a reference for the development of internal education and training as well as design guidelines to increase design efficiency in your department.
6. You, as a project manager, can anticipate design defects and remind designers to respond in time to improve the overall product development efficiency.
