More than ever, managers are expected to perform data-driven decision-making in their organizations. We intend to contribute to that trend with a short book which presents some quantitative methods which are frequently used in managerial settings. Recent developments in the software industry have greatly enlarged the computational capabilities for data analysis purposes. This has facilitated incorporating quantitative methods into all business areas in order to solve interesting questions such as do we have a gender pay-gap in our firm? Can we predict which borrowers will not pay back a loan? What is the optimal mix of fixed and variable salary to increase productivity? What type of promotions enhances customer retention? What is the better route for delivering our products in rural areas?

管理者比以往任何时候都更需要在其组织中执行数据驱动的决策。我们打算用一本简短的书来帮助这一趋势，这本书介绍了一些在管理环境中经常使用的定量方法。软件产业的最新发展大大扩展了数据分析的计算能力。这有助于将量化方法纳入所有业务领域，以解决有趣的问题，例如我们公司是否存在性别薪酬差距？我们能预测哪些借款人不会还贷吗？固定工资和可变工资的最佳组合是什么来提高生产率？什么样的促销活动可以提高客户保留率？在农村地区提供我们产品的更好途径是什么？
