he technology design process, like scientific inquiry, does not always follow rigid steps. Often, engineers follow a common process: They identify a need, research the problem, design a solution, build and evaluate a prototype, troubleshoot and redesign, and communicate the solution.
A prototype is an early sample, model, or release of a product built to test a concept or process or to act as a thing to be replicated or learned from. ... A prototype is generally used to evaluate a new design to enhance precision by system analysts and users.
Engineers fix flaws and any other problems that they could have came across. Also, redesigning can lead to improvements of the product
Engineers find solutions to the problems faced by the society . Once the solution has been devised the engineers communicate it to the laborers and the workers so the implement it on field or on the work stations.
