It does not need a PHD in business to unravel the hallmarks of a leaderless organisation. Whether in private and public sectors, the symptoms are similar, easily diagnosable, but sometimes disguisable. By saying leaderless, the organisation is certainly purposeless. The most common things among such organisations are that:
Their visions are abstract and clueless statements.
Their communication is manipulative, mechanical and very corporate.
For public sector organisations, their cultures are procedural and their polices are godly and biblical. They are unchallengeable. Creativity causes anxiety and creative people inside are alienated.
