(FORTUNE Magazine) – GINGER S. EVANS, 36 CITY OF DENVER AVIATION DEPARTMENT Compared with growing up on her parents' Colorado farm, her job is easy, Evans says. As construction chief for the future Denver International Airport -- the first new U.S. airport since Dallas-Fort Worth opened in 1974 -- she never has to stay up all night with a sick calf. Still, she has her hands full keeping the project on schedule -- the planes are slated to start taking off in October 1993 -- and staying within a $1.9 billion budget. Evans got the post after distinguishing herself as an engineer at Denver's Stapleton Airport, which will be torn down. Looking ahead, Evans would like to work on a light- rail system for car-congested Denver. Says she: ''It would be challenging to help solve a problem that some people consider unsolvable -- air quality.''

INDRA K. NOOYI, 35 ASEA BROWN BOVERI INC. Nooyi likes to say she works at a ''$6 billion startup'' because her Connecticut company, like its Swiss-Swedish parent, is a collection of acquisitions that need to be knitted together. A former Motorola strategist, she joined the builder of power plants and industrial equipment last summer. One of her jobs as head of strategy: to discover how various divisions can pull together to solve clients' problems. Recently she helped build a team of managers from 15 ABB businesses to assist electrical utilities in complying with the stringent Clean Air Act. Nooyi has taken on daunting tasks before. In 1977, as a Johnson & Johnson product manager, she introduced Stay-Free sanitary napkins to her native India, where the advertising of such items was severely restricted.

NEAL M. WADDINGTON, 44 SEQUENT COMPUTER SYSTEMS INC. After 19 years at Sperry and at its successor company, Unisys, Waddington was the top-ranking marketing executive, and he could easily have finished out his career there. Instead, last May he became head of marketing at this Oregon computer company. Says he: ''I think Sequent is part of a revolution that will see a reordering of the computer industry around open systems that link * together, rather than proprietary ones.'' Sequent specializes in systems that provide timely data to such users as reservation clerks. Waddington is expanding the customer base from midsize companies to large ones and boosting international business. Overseas direct sales more than doubled in 1990.
