Artificial intelligence (AI) can revolutionise business, but it should not be deployed unless there is a solid business case for it. This is according to Johan Steyn, chair of the Institute of Information Technology Professionals South Africa's (IITPSA) AI and robotics special interest group (SIG), who was addressing the Institute's first Tabling Tech Webinar this week. Steyn said AI could improve business in areas ranging from HR, sales and finance through to R&D and customer service. In fields such as human capital management, AI could enhance recruitment by scanning candidates' social media feeds and monitoring their micro-expressions during interviews; it could help personalise training and development programmes and pre-empt the loss of key skills. In sales, AI could ensure products and services met customer needs and wants, and predict market changes.
