  • Outsourcing moves up the maintenance ladder

    Outsourcing of non-core operations within a company, large or small, is now a well established corporate strategy. By entrusting services such as IT support, accounting, human resources and other “back office” activities to specialist firms prepared to do the job at an acceptable price, chemical companies can concentrate on their main business — where they are the specialists. That's the theory, at least.
