Design is the most important step where in all engineers are involved. Design of components are most important, which gives results more appropriate. Designing is a continuous improvement for day to day analysis work which is generally utilized by engineers to make the most effective resource management through out the world. Here the question comes "How to design a component in easier way?" In earlier days we are aware of designers, like an example one designer wants to design a part which is starting stage of product life ccle. here the question comes like life cycle steps are Introduction, design, validate, analyse, then again validate, manufacture and delivery to end customer. but here we have seen only 5 to 6 steps,but in each department we'll have these all steps for making the customer satisfied with the product. The most easiest way to design depends on analysis and thinking of component design and evaluation. The simpler the design and mos convenient way to manufacture is the most challenging part of engineers. Here we have lakhs and crores of engineers around the world are in different domains like Mechanical, Electrical, Civil, Electronics,IT etc to make the change in day to day design. But most important thing for engineers are reduce cost and make simple design with most precise components. Each one of us are proud to have such engineers to design different designs with their thoughts and make us delight towards the way they approach and finally my quote is " Engineers are meant to make Mistakes". With the mistakes they are coming up with new techniques and approaches.
