Structural and mechanical engineering brings realization to design ideas. Just because engineering is grounded in physical processes and materials doesn’t make it less creative than any other design process. And therein lies the rub.
The research literature on creativity in engineering can be summarized simply: creativity is notoriously hard to objectify, quantify, qualify, and otherwise manage. There are various creative techniques organizations use to aid the creativity process, most notably brainstorming. Various role-playing scenarios are occasionally used, but most engineers are loathe to engage in such practices. Creativity at the requirements stage is considered particularly painful because engineers want to move on to what is perceived as the more useful and productive processes.
Yet the creative aspects are necessary. When a team suddenly sees a radically different way to achieve a goal, it challenges the organization to make sure the new idea is not just different, but better. Properly managed, creativity can become the catalyst to innovation.
