The phases of the outsourcing process and the actions required are discussed. The most difficult and the most important phase of o a successful outsourcing process is to know what activities to outsource. The criteria for suppliers selection must be developed and should cover the reasons why the activity is being outsourced, the expected benefits and potential dangers. Contract negotiation is a very important phase of the outsourcing contract in which rules of the outsourcing are set. The transfer of activity phase corresponds to the reassignment of control of the outsourced activity from the outsourcer to the contractor.

We study two distinctly ordered condensed phases of polypeptide molecules, amyloid fibrils and amyloidlike microcrystals, and the first-order twisting phase transition between these two states. We derive a single free-energy form which connects both phases. Our model identifies relevant degrees of freedom for describing the collective behavior of supramolecular polypeptide structures, reproduces accurately the results from molecular dynamics simulations as well as from experiments, and sheds light on the uniform nature of the dimensions of different peptide fibrils. © 2012 American Physical Society.
