I guess in all probability an organisation is alarge team.It could be functional or dysfunctional.So I think "evolving" an organisation into "teams" may not be thrust.Instead what needs to be understood is the dynamics of change.What aspects of an organisation are being over-used/employed,what are active,what are latent ?Here may lie the key to functionality or dysfunctionality.Some managers may not want to be in teams because it hinders individual accomplishment.Some may want teams so that they may deflect non-performance over many people.These are the key issues.
