The practice of using an organisation’s own personnel or other resources to accomplish a task that was previously outsourced. For this to be effectively analysed, budgeted and controlled, the steps of the process, the inputs and efficiency with which outputs are produced, as well as the costs and integration with the enterprise as a whole need to be full documented, analysed and measured. The Opagio Blueprint enables each of these features to be systematically monitored, before and after change is effected.
