Collaboration is working with each other to do a task.[1] It is a recursive[2] process where two or more people or organizations work together to realize shared goals, (this is more than the intersection of common goals seen in co-operative ventures, but a deep, collective, determination to reach an identical objective[by whom?][original research?]) — for example, an intriguing[improper synthesis?] endeavor[3][4] that is creative in nature[5]—by sharing knowledge, learning and building consensus. Most collaboration requires leadership, although the form of leadership can be social within a decentralized and egalitarian group.[6] In particular, teams that work collaboratively can obtain greater resources, recognition and reward when facing competition for finite resources.[7] Collaboration is also present in opposing goals exhibiting the notion of adversarial collaboration, though this is not a common case for using the word.
