Testimonials from colleagues, past and present, agree that, as an ambassador for the profession, Willean Master has consistently improved procurement perceptions both internally and externally. At G4S, she has led procurement strategies for the global team and has managed spending valued at more than £43 million. Master is an established leader, coach and mentor, and a keen supporter of other professionals with a strong belief in the circle of reciprocity. She encourages and empowers other procurement professionals to use their voice to make effective changes both personally and professionally, and leads by example with a visible track record of success. In 2015, she helped transition procurement at G4S from a devolved function to a centralised one, gaining senior management buy-in. Master created a professional team to manage ‘cradle to grave’ activities through training and technology, and managed the consolidation/re-engineering of seven stores and archives around the UAE with £2 million in stock with unexplained variances, turning it around to become a value added.
