1a、Explain what a cause-and-effect diagram is.
A cause-and-effect diagram, also known as Ishikawa or fishbone diagram, is a visual tool used in quality management and process improvement to analyze the root cause(s) of a specific problem or event. It represents a systematic approach to identify all possible factors that contribute to an effect, by arranging them in a graphical format that resembles the shape of a fish skeleton. Each cause is represented by a branch extending from the main "spine" of the diagram, and the relationship between causes and effects is clearly depicted. The purpose of a cause-and-effect diagram is to help teams focus on the most significant causes and to identify potential solutions to prevent or resolve the problem.
翻译：因果图，也称为石川图或鱼骨图，是用于质量管理和过程改进的可视化工具，用于分析特定问题或事件的根本原因。它代表了一种系统的方法，通过将它们以类似于鱼骨架形状的图形格式排列，来确定促成效果的所有可能因素。每个原因都由从图的主“脊柱”延伸出来的分支表示，原因和结果之间的关系被清楚地描绘出来。因果关系图的目的是帮助团队专注于最重要的原因，并确定预防或解决问题的潜在解决方案1b、Cycle time analysis provides valuable intormation about process performance.

1c、The following steps are used by a computer manufacturer to handle the order fulfilment process:
2a、Compare and contrast the concepts of Demand Pull and Supply Push for the material flow.比较和对比物料流的需求拉动和供给推动的概念。
Demand Pull and Supply Push are two different approaches to managing the flow of materials in a supply chain.
Demand Pull is a method of production management that focuses on responding to customer demand. In this approach, production is initiated only when there is a confirmed order from the customer, and the goal is to minimize inventory levels and minimize waste. This approach is often used in just-in-time (JIT) production systems.
Supply Push, on the other hand, is a method of production management that focuses on proactively producing and delivering products, without necessarily having a confirmed customer order. In this approach, companies aim to maintain a steady flow of production to meet anticipated demand. This approach is often used in forecast-driven production systems.
In summary, Demand Pull focuses on customer demand, while Supply Push focuses on production and delivery.

Business Process Reengineering (BPR) and Business Process Improvement (BPI) are two approaches aimed at improving business processes.
BPR is a radical redesign of a company's core processes to achieve significant improvements in productivity, cost and quality. It involves rethinking the way a business operates from the ground up, and often involves the elimination of unnecessary steps and the automation of remaining processes.
BPI, on the other hand, focuses on incremental improvements to existing processes. It aims to identify inefficiencies, eliminate waste, and streamline processes to achieve improved outcomes. BPI is less disruptive than BPR, but it may also result in limited improvements.
In the case of the United States Postal Service (USPS), both BPR and BPI can bring advantages. For example, BPR could help the USPS re-evaluate its entire delivery process and find ways to streamline it. On the other hand, BPI could help the USPS identify bottlenecks in its current process and find ways to improve them.
Advantages of these improvement programs for the USPS could include:
Increased efficiency and productivity
Improved customer satisfaction
Increased revenue and cost savings
Better alignment of processes with customer needs and expectations
It is important to note that while both BPR and BPI offer advantages, they each have their own unique challenges and risks. Therefore, it is important for the USPS to carefully consider the best approach for their specific needs and objectives.

System development process is a sequential,multistage process to develop information systems.Using any of the systems in the case study as an example,explain the major goals of the system
analysis and system design phases.
系统开发过程是一个有序的、多阶段的信息系统开发过程。使用案例研究中的任何一个系统作为例子，解释系统的主要目标
分析和系统设计阶段。
System Analysis:
Define the problem: The goal of the system analysis phase is to clearly define the problem or opportunity that the information system is meant to address. This involves gathering requirements from stakeholders and analyzing the current system to identify areas for improvement.
Determine feasibility: In this phase, the analyst must determine if the proposed solution is technically and economically feasible. This includes an evaluation of the resources required and the potential benefits of the proposed system.
Develop a conceptual solution: Based on the information gathered in the first two goals, the analyst must develop a conceptual solution that addresses the problem or opportunity.
System Design:
Detail the design: In the system design phase, the conceptual solution is transformed into a detailed design that outlines how the system will function and how it will meet the requirements gathered in the system analysis phase.
Specify hardware and software requirements: The system design must specify the hardware and software requirements for the new system. This includes the hardware platform, software tools, and programming languages required to build and operate the system.
Develop prototypes: A prototype of the system may be developed in order to test and refine the design. This helps to identify any design flaws or areas for improvement before the system is built.
As an example, let's consider the United States Postal Service's (USPS) automated sorting system used for processing mail. During the system analysis phase, the USPS would have defined the problem of manual sorting being slow and prone to errors, determined the feasibility of an automated sorting system, and developed a conceptual solution to automate the sorting process. During the system design phase, the USPS would have detailed the design of the automated sorting system, specified the hardware and software requirements, and developed prototypes to test and refine the design.
