The president of the company believes that the prosecution procedure should allow prosecutors and defendants to choose mediators who will help them solve the problem. The cost of prosecution is high, and the mediator is likely to solve most of these problems. However, the suggestion from the company's human resources department is to start mediation later in the prosecution process, which has little effect.
The statement 'The mediation process itself will take as much time as the current prosecution procedure' strongly supports the criticism of the president of the company to the criticism of the HR.
