Some of the advantages of a temp-to-perm staffing approach will include:

a): Being able to test in real situations on the field your resources. Contrasting what's in a paper resume with reality.

b): Comparing individuals, their competitiveness and soft skills required for the position.

c): Not committing to individuals that will need more investment in development to take them to the desired point in the learning curve.

Some of the disadvantages for management will involve:

a): Time consuming introduction and coaching activities in resources that will be discarded.

b): Higher cost and bureaucracy from the need to use an external agency to hire temporary workers according to law and regulations in some fields of work.

c): Inability to find or scare high-level resources who are not willing to go through a temporary contract.
