Present theories highlight the varied roles played by weak and strong ties in idea generation, and development, respectively, but the mechanisms through which ties operate to influence the creative process remain uncertain. Investigating this issue across a range of SMEs, this paper demonstrates that strong ties influence idea development through three mechanisms; endorsement and validation, developing cognizance, and encouraging constructive dissent. These mechanisms positively impact idea development by creating organizational spaces that are primed to critically receive ideas, energize knowledge sharing by better transacting resources across network connections, and drive divergent thinking by disordering, but not fracturing, social spaces.
