Develop the greatest difficulties in Support Planning, indicating their causes.
在 Support Planning 中提出最大的困难，指出其原因。

The biggest difficulty in the support plan refer to determine what the standard of strategy is and whether our strategy is correct.
支持计划中最大的难点是指确定策略的标准是什么，我们的策略是否正确。

Because it will affect the executor and operation.If we can determine the indicators, we can actively and effectively guide the executors and operations, and achieve the success of the project through these continuous improvements.
因为它会影响 executor 和 operation。如果我们能确定指标，就能积极有效地指导执行者和运营，并通过这些持续改进来实现项目的成功。

Exercise 3.02
练习 3.02

Elaborate why it is advisable to develop Models to structure Support Operations.
详细说明为什么建议开发模型来构建支持操作。

Because the operation you have established as a model model globally depends on the industry and the department .If our company does not work as a model, then it will work .Whether the work is feasible is indisputable. We need to build a correct model to support it . In the correct mode, the activities in the operation are divided into three parts.
因为您在全球范围内建立的模型操作取决于行业和部门。如果我们公司不作为模型工作，那么它将工作。这项工作是否可行是无可争议的。我们需要建立一个正确的模型来支持它。在正确的模式下，操作中的活动分为三个部分。

Production: Production only starts with raw materials. Carefully made to the end. products are production lines in factories. In the different  chains that we transform raw materials and final product. Such products can be  physical, products can be digital, products doesn't matter. Production is the process of everything. From raw materials to final products, they all undergo processing engineering. The risk production is the exception of production is closed.
生产： 生产仅从原材料开始。精心制作到最后。产品是工厂的生产线。在我们转换原材料和最终产品的不同链条中。这样的产品可以是实体的，产品可以是数字的，产品无关紧要。生产是一切的过程。从原材料到最终产品，它们都经过加工工程。风险生产是生产关闭的例外。

Cost: From planning our career to having a limited one, we proposed some prices. If we set the same price for our products, we must limit our costs. Of course, we cannot be free, we need to establish cost constraints, followed by indicators and production risks. Internationally known as total cost of ownership. Cost ownership.
成本：从规划我们的职业生涯到拥有有限的职业生涯，我们提出了一些价格。如果我们为我们的产品设定相同的价格，我们必须限制我们的成本。当然，我们不能自由，我们需要建立成本约束，其次是指标和生产风险。国际公认的总拥有成本。成本所有权。

Fulfillment: Fulfillment usually refers to the process in which a company delivers products or services to customers in accordance with the requirements of an order or contract. This includes a series of activities such as order processing, inventory management, logistics distribution, and after-sales service. The goal of fulfillment is to ensure that customers can obtain the required products or services on time, in quantity, and with quality, thereby improving customer satisfaction and loyalty.
履行： 履行通常是指公司根据订单或合同的要求向客户交付产品或服务的过程。这包括订单处理、库存管理、物流配送和售后服务等一系列活动。配送目标是确保买家能够按时、按量、按质量获得所需的产品或服务，从而提高买家满意度和忠诚度。

Exercise 3.03
练习 3.03

Explain why Efficiency is the preferred management metric for Production. Where dose this metric come form?
解释为什么 Efficiency 是 Production 的首选管理指标。这个指标来自哪里？

Because in production, efficiency is indeed closely related to fulfillment.
因为在生产中，效率确实与履行密切相关。

This indicator will come from these aspects:
这个指标将来自以下几个方面：

Cost: Reasonable cost control is an important factor in improving efficiency. In the production process, if costs are controlled and labor, raw materials, energy, and other resources are used reasonably, it will save resources and naturally improve production efficiency. Reducing inventory costs and resource waste in lean production can directly improve production efficiency. So cost control affects efficiency.
成本：合理的成本控制是提高效率的重要因素。在生产过程中，如果控制成本，合理使用人工、原材料、能源等资源，就会节约资源，自然而然地提高生产效率。降低精益生产中的库存成本和资源浪费，可以直接提高生产效率。所以成本控制会影响效率。

Fulfillment: Production efficiency cannot be solely based on input-output ratio. Obtaining the required products or services on time, in quantity, and with quality can improve customer satisfaction and loyalty. Therefore, efficiency must be improved without affecting the final implementation. If only pursuing high efficiency and neglecting to achieve goals, it may lead to a decline in product quality or failure to deliver on time. So fulfillment serves as a measure of efficiency.
履行： 生产效率不能仅仅基于投入产出比。按时、按量、按质获得所需的产品或服务可以提高客户满意度和忠诚度。因此，必须在不影响最终实施的情况下提高效率。如果只追求高效率，忽视目标的实现，可能会导致产品质量下降或无法按时交货。因此，履行是衡量效率的指标。

Exercise 3.04
练习 3.04

Explain why Time is the preferred Guarantee management metric. Where does this metric come from?
解释为什么 Time 是首选的 Guarantee 管理指标。此指标从何而来？

Because there is a close relationship between ensuring management indicators and stability and Security, time is the measure of stability and Security.
因为确保管理指标与稳定性和安全性之间存在着密切的关系，所以时间是衡量稳定性和安全性的标准。

Stability: Stability refers to the ability to work in the same way when encountering any event or malfunction, involving how to handle, repair, and solve different problems. So, the measure of stability is based on the number of events and the time it takes to solve the problem. If there are few events and the solution time is short, it indicates that the operation is in good condition.
稳定性：稳定性是指在遇到任何事件或故障时以相同方式工作的能力，涉及如何处理、修复和解决不同的问题。因此，稳定性的衡量标准基于事件的数量和解决问题所需的时间。如果事件少，求解时间短，则说明操作状态良好。

Security : Security refers to preventing products or services from being stolen by malicious elements, and its measurement standard is compliance, including confidentiality, integrity, and availability; Confidentiality refers to the provision of products or information only to legitimate individuals to prevent information from being obtained by attackers; Integrity refers to the process of a product or information remaining unchanged from start to finish.
安全性 ：安全性是指防止产品或服务被恶意分子窃取，其衡量标准是合规性，包括机密性、完整性和可用性;保密性是指仅向合法个人提供产品或信息，以防止信息被攻击者获取;完整性是指产品或信息从头到尾保持不变的过程。

Exercise 3.05
练习 3.05

Explain why Replacement is the preferred metric in Actor Support. Where does this metric come from?
解释为什么 Replacement 是 Actor Support 中的首选指标。此指标从何而来？

Because in order to ensure the normal operation of all things, We need to provide a replacement solution. Therefore, if the event encounters problems during normal operation, using replacement can be a solution and will help the event run smoothly and in a timely manner.
因为为了保证万物的正常运行，我们需要提供替代解决方案。因此，如果活动在正常运行过程中遇到问题，使用 replacement 可能是一种解决方案，将有助于活动顺利、及时地进行。

Metrics come from availability, to ensure continuous access to remote courses, redundancy can be achieved by setting up twice the number of personnel, equipment, computers, etc; If there are two teachers teaching at the same time, or if there are fewer cases of poor performance among three teachers at the same time, this means redundancy; Reducing the number of accidents means improving availability, such as timely computer repairs.So replacement can ensure availability.
指标来自可用性，为保证持续访问远程课程，可以通过设置两倍数量的人员、设备、计算机等来实现冗余;如果有两名教师同时授课，或者如果三名教师同时表现不佳的情况较少，则意味着裁员;减少事故数量意味着提高可用性，例如及时修复计算机。所以更换可以保证可用性。

I look forward to hearing from you, Professor. Thank you very much, Professor.
教授，我期待着您的来信。非常感谢您，教授。
