Engineer role is to adapt the design based on the working environment and also wants to provide suitable solution based on the source what we have.

Because engineers all have to make decisions. Engineers face problems every day that need solving. Whether the issue is big or small, engineers all set goals for themselves, face challenges, and strive to overcome.
