求翻译：当然，想通过管理运营风险来降低成本，企业必须转变观念，制定更全面的战略，并改变心态。它们必须放弃静态、以产品为基础（即确定）的成本观念，转而树立更人性化、动态、可变（即不确定）的成本观念，认识到裁员是一种损失价值、最不可取的手段。它们还需要建立评估和衡量运营成本的机制和指标。是什么意思？

Of course, want to reduce costs by managing operational risk, companies must change their old concepts, develop a more comprehensive strategy, and changes the State of mind. They must give up static, based on a product (that is, determine) idea of cost, to establish a more human, dynamic, variable (that is, not sure) cost concept, recognizing that layoffs are a loss of value, most undesirable means. They also need to establish a mechanism for evaluating and measuring the operational costs and indicators.
