📚 Project Management (A Level) | A Level 商务：项目管理
Project management is the discipline of planning, organising, motivating and controlling resources to achieve a specific one-off objective within defined time, cost and quality constraints. For Cambridge A Level Business students, project management is not just about Gantt charts; it links operations strategy, capacity planning, finance and human resource management.
项目管理是计划、组织、激励和控制资源，以在明确的时间、成本和质量约束下实现特定一次性目标的学科。对剑桥 A Level 商务学生来说，项目管理不仅是甘特图，它还联系运营战略、产能规划、财务和人力资源管理。
1. What Is a Project? | 什么是项目？
A project is a temporary, unique undertaking with a clear start and finish, designed to produce a specific output such as a new product, a relocated factory or a marketing campaign. It differs from routine operations, which are repetitive and continuous.
项目是一种临时、独特的任务，有明确的开始和结束，旨在产出特定成果，例如新产品、搬迁工厂或营销活动。它不同于常规运营，后者是重复和持续进行的。
A Level exam questions often ask students to distinguish between a project and ongoing operations. Key terms include one-off, non-repetitive, finite timescale, dedicated team and specific objectives.
A Level 考试常要求学生区分项目与持续运营。关键词包括一次性、非重复、有限时间、专门团队和具体目标。
Examples of business projects include launching an e-commerce website, installing new software, opening a branch or organising a trade show. Each has a defined deliverable and a limited budget.
商业项目的例子包括推出电子商务网站、安装新软件、开设分店或组织贸易展。每个项目都有明确的可交付成果和有限预算。
2. Key Features of Project Management | 项目管理的关键特征
Effective project management balances the triple constraint of time, cost and quality, sometimes called the project triangle. If one constraint changes, the other two are usually affected.
有效项目管理需要平衡时间、成本和质量这三个约束，有时称为项目三角。如果一个约束改变，另外两个通常会受到影响。
The project manager is responsible for defining the scope, assembling a project team, allocating resources, monitoring progress and reporting to stakeholders. Leadership and communication skills are therefore as important as technical planning ability.
项目经理负责界定范围、组建项目团队、配置资源、监控进展并向利益相关者报告。因此，领导力和沟通能力与技术规划能力同样重要。
Other key features include a cross-functional team drawn from different departments, a high degree of uncertainty and risk, and a fixed budget that must be controlled throughout the project.
其他关键特征包括由不同部门人员组成的跨职能团队、较高的不确定性和风险，以及必须在整个项目过程中加以控制的固定预算。
3. The Project Life Cycle | 项目生命周期
Most projects pass through four broad stages: initiation, planning, execution and closure. In initiation, the business identifies the need, sets objectives and carries out a feasibility study.
大多数项目经历四个主要阶段：启动、规划、执行和收尾。在启动阶段，企业识别需求、设定目标并开展可行性研究。
During planning, tasks are broken down, durations estimated and resources scheduled. Execution involves coordinating people and budgets, while closure includes handover, review and evaluation against objectives.
在规划阶段，任务被分解、估算工期并安排资源。执行阶段涉及协调人员和预算，收尾阶段包括移交、审查并根据目标进行评估。
Exam answers that refer to the life cycle demonstrate an understanding that project management is dynamic, not a one-off plan made at the beginning and then forgotten.
提到生命周期的考试答案表明考生理解项目管理是动态的，而不是一开始制定后就忘记的一次性计划。
4. Project Planning Tools: Gantt Charts | 项目规划工具：甘特图
A Gantt chart is a horizontal bar chart showing project tasks against time. Each bar represents a task, its start date, duration and finish date, making progress easy to visualise.
甘特图是一种横向条形图，显示项目任务与时间的关系。每个条形代表一项任务及其开始日期、持续时间和完成日期，使进度易于可视化。
Gantt charts help managers see which tasks overlap, where bottlenecks may appear, and whether the project is behind schedule. However, they do not show task dependencies clearly.
甘特图帮助管理者了解哪些任务重叠、瓶颈可能出现的位置以及项目是否落后于计划。但是，它们不能清晰显示任务之间的依赖关系。
For A Level analysis, use Gantt charts to discuss communication, resource smoothing and progress monitoring, but criticise their weakness in showing complex interdependencies.
在 A Level 分析中，可以用甘特图讨论沟通、资源平滑和进度监控，但也要批评它在显示复杂相互依赖关系方面的弱点。
5. Introduction to Critical Path Analysis | 关键路径分析简介
Critical path analysis (CPA) is a quantitative planning technique that identifies the longest sequence of dependent tasks in a project. The critical path determines the shortest possible completion time.
关键路径分析（CPA）是一种定量规划技术，用于识别项目中相互依赖任务的最长序列。关键路径决定项目的最短可能完成时间。
CPA uses a network diagram of activities, drawn from left to right. Each activity is shown as a node, and arrows indicate the order in which tasks must be completed.
CPA 使用从左到右绘制的活动网络图。每项活动用一个节点表示，箭头表示任务必须完成的顺序。
The technique is especially useful for complex projects such as construction, product launches and large events, where many tasks must be coordinated at the same time.
该技术对复杂项目尤其有用，如建筑、产品发布和大型活动，因为这些项目需要同时协调许多任务。
6. Drawing a Network Diagram | 绘制网络图
To draw a network diagram, first list all activities, their durations and immediate predecessors. Activities with no predecessors start from the first node; dependent activities follow in sequence.
要绘制网络图，首先列出所有活动、其工期和紧前活动。没有紧前活动的活动从第一个节点开始；有依赖关系的活动按顺序排列。
| Activity | Duration (weeks) | Predecessor |
| A | 6 | None |
| B | 3 | None |
| C | 4 | A |
| D | 5 | B |
