Answer:
a high risk venture because the costs of reversing the decisions are often high
Explanation:
Outsourcing refers to a business function whereby a firm decides to assign the performance of it's less important routine tasks to another firm who specializes in performance of those tasks.
By Outsourcing, a firm is able to devote more time to those processes which are integral and important and also gains by the specialization of the firm in performance of those routine tasks.
Such an activity is a high risk venture in the sense once a firm decides to outsource it's internal task, the talent and creativity of the employees who were supposed to perform that task initially is given up in exchange for availing specialized services.
So if a firm decides to reverse i.e give up outsourcing and assign those tasks to it's own workforce, the costs would now be higher.
