Financial services consultancy Capco has promoted Ismail Amla, formerly head of Capco's UK operations, to lead its North America business. Amla will be replacing Tom McKelvey, who until recently served jointly as Capco's North America business leader and chief operating officer. McKelvey will continue in the latter role. Amla joined Capco last year from Accenture, where he was responsible for the firm's outsourcing business. Andrew Tarver, a Capco partner, will succeed Amla as head of UK operations.
