This article explores the National Aeronautics and Space Administration's (NASA's) journey to strategic agility through successively shifting to three different strategic alignments over the last six decades and suggests that logical incrementalism may be an unappreciated driver of this process. Three successive alignment models exhibit important shifts in technology strategy, competencies, and values of the organization. The three phases of incremental changes in shifting from one alignment model to the next are the emergence of new approaches, the embeddedness of these approaches in particular contexts, and their expansion to other organizational contexts.

Singapore Airlines is widely regarded as an exemplar of excellence in an industry whose service standards are tumbling. What's not so well known is that the company is also one of the civil aviation industry's cost leaders. SIA's success in executing a dual strategy of differentiation and cost leadership is unusual. Indeed, management experts, such as Michael Porter, argue that it's impossible to do so for a sustained period since dual strategies entail contradictory investments and organizational processes. Yet SIA, and a few other emerging-economy companies, view the dualities as opposites that form part of a whole. SIA executes its dual strategy by managing four paradoxes: Achieving service excellence cost-effectively, fostering centralized and decentralized innovation, being a technology leader and follower, and using standardization to achieve personalization. The results speak for themselves: SIA has delivered healthy financial returns; it has never had an annual loss; and except for the initial capitalization, the Asian airline has funded its growth itself while paying dividends every year.
