I have spent many years in an industry where mining engineers were ad agency entrepreneurs, chemical engineers and MBAs from top-notch schools were strategising on how to sell more floor cleaners and commerce graduates were great TV scriptwriters. But in most industries, not only a basic qualification to do that job is essential, but it is increasingly important to skill up on related fields. If you are a coder, maybe design thinking as a discipline can enhance your skills. If you have graduated in design, maybe a course in digital marketing may help you market your skills better or help you develop a better understanding of the pressures of the marketing manager you maybe working with. Unfortunately, aside from a short course in usability, I have not invested in learning new skills — especially those with certification. In that context, I admire those who constantly learn and make it a lifelong process.
