These problems caused negative effects, such as: missed market opportunity due to the delay of launch after product was developed; decrease of customer satisfaction due to low quality level; extended investment return period induced by project budget out of control. 这些问题导致新产品在开发完成后,由于无法及时推出而错失市场机遇,质量水平不高使客户满意度下降,及项目成本超出预期使回报周期拉长等结果,降低了新产品的市场竞争力。
