Lowell L. Bryan and Claudia I. Joyce, Mobilizing Minds, 2007:

The truth is that almost all of today's companies, from the mediocre to the "superclass," were built primarily to mobilize their labor and capital assets–not the intangile assets that enable profits per employee to rise to levels never seen before. Trying to run a company in the 21st century with an organizing model designed for the 20th century places limits on how well a company performs. It also creates massive, unnecessary, unproductive complexity–a condition that frustrates workers and wastes money. The plagues of the modern company are hard-to-manage workforce structures, thick silo walls, confusing matrix structures, e-mail overload, and "undoable jobs."
