Forecasting in professional services has never matched the maturity of other industries. However, this is becoming a bigger problem as technology projects become shorter in duration and narrower in scope. Revenue backlog simply doesn’t stretch as far into the future as it once did. Faced with a less certain revenue and resource demand outlook, a “wait until you win, then react” operating style prevails. This puts pressure on margins, strains delivery teams, limits agility, and makes business models vulnerable to more progressive approaches. Yet, most of the industry is still forecasting in spreadsheets. It’s time for professional services to match other industries in forecasting innovation by deploying modern technology, more comprehensive methods, and real-time data.
