产品范围vs Project Scope

Projects are undertaken to deliver a product, service, or result. It will be difficult to achieve your objective if you don’t understand both the project and product scope. In project management, you will find many important concepts vital to complete your project with minimal obstacles. Among these terms and concepts, project scope and product scope stand out.

Project scope depends entirely on the product scope. You must understand the product scope to define the project scope. These are the most important concepts in project management. I have noticed that many professionals incorrectly use these terms synonymously.

I saw a related question posted in a PMP forum a few days ago. Someone was asking for clarification on the differences between project scope and product scope. There were many replies; however, some were incomplete, and a few of them were wrong. It seemed like the posters were more concerned with supporting their own opinions.

这些答案都没有达到要求的期望，老实说，查询没有得到答复。

这是论坛的主要缺点之一：您无法识别正确的答案。您可能会接受任何适合您已经相信的错误答案。论坛非常适合阅读经验教训和其他故事，但对您的技术问题澄清不利。

因此，我决定撰写有关项目范围和产品范围的博客文章。

在开始讨论之前，请确保我们了解术语产品，项目和范围。

什么是产品？

PMBObob手机客户端K指南第六版将产品定义为工件或可量化的产品本身或组件项目。这些项目也称为材料或商品。

In other words, a product is defined as a substance or article produced during a natural, chemical, or manufacturing process. You can characterize a product in many ways, such as by its physical properties and chemical properties.

For example, if a computer is the product, its characteristics are its processor, screen size, memory, and hard disk.

What is a Project?

According to the PMBOK Guide, “A project is a temporary endeavor undertaken to create a unique product, service, or result.”

定义的前半部分说该项目的性质是暂时的。这意味着一旦输出输出，your project因为您已经实现了目标，因此不再存在。

The second half says that the project produces a deliverable. Projects are undertaken to produce a particular output, which can be tangible or intangible.

什么是范围？

可以将范围定义为附加到所附术语的范围，细节或边界。范围一词并不总是独立的。它用作后缀或另一个术语的前缀。

If used with the term product, it means the details of the product, or when used with the project, it means the details of the project.

According to the PMBOK Guide, the scope is the sum of the products, services, and results to be provided as a project.

产品范围

In short, product scope is about the product details; what the product will look like, how it will work, its features, and more.

According to the PMBOK Guide, sixth edition, product scope is the features and functions that characterize a product, service, or result.

For example, if the product is a bridge, the product scope might be its length, width, and load strength. If the product is a cell phone, its product scope will be its screen size, battery backup, processor speed, camera type, and memory.

However, for services, the product scope will give you details on the tasks and responsibilities of the person who will deliver.

In the case of a result, the product scope can be the information required from the result.

如何确定产品范围

Most of the time, the product scope is defined by the people who have higher levels of business expertise. Usually, a business analyst defines the product scope, and although the project manager can be consulted, their role is limited.

The business analyst will meet with everystakeholderto understand their expectations and requirements regarding the final product. Once these are finalized, the analyst will get them signed by stakeholders and then process them for approval.

确保在此过程中均未遗漏任何要求，因为在项目结束时增加更多的要求可能是昂贵的。产品范围的略有变化可能比项目范围声明的初始更改要花费更多的钱。产品范围应得到很好的定义，因为项目范围是根据产品范围定义的。

产品范围是将您和您的组织与将使用该产品的用户束缚的原因。您应该尽一切努力使这些规格精确而完整。

However, if you have a contract to deliver the product to the client, you will find the product scope attached to the合同document.

Project Scope

The project scope defines the requirements of the product and the work required to create it. This also defines what is inside and outside of the scope, which helps you avoidscope creep。

根据PMBOK指南（第六版），项目bob手机客户端范围是为提供指定功能和功能的产品，服务或结果而执行的工作。

项目范围声明解释了预期的结果constraints and assumptions。这有助于achieving the product scope. Project scope is also known as scope statement or statement of work.

If you are given a project to construct a bridge, the project scope will provide insight into how to build the bridge. It gives you all the required information. In this case, the project scope defines what exactly you need to construct the bridge. Nothing more.

How to Determine the Project Scope

项目经理定义了项目范围，这取决于许多因素。

For example, if you receive a firm-fixed-price contract, the client will give you a well-defined product description, which helps you in developing the project scope statement. In this case, you won’t have to worry too much about the project scope.

但是，情况并非总是如此。让我们考虑另一种情况。

Your organization initiates a project, and you are the project manager.

In this case, you may have to build the project scope statement from scratch. You contact the concerned stakeholders to collect the requirements and compile them, and then you get them approved by management.

同样，可能有几个因素决定了项目范围，例如客户要求您代表他们做所有事情。

写得很好的范围声明使项目经理的生活更加舒适，并且该项目将在障碍较少的情况下完成。项目范围是您与客户或您的客户之间的协议组织。

Project scope binds you and your project team to your organization; therefore, it should be very lucid and detailed. This document must be completed at an early stage of the project. An effective scope statement is necessary to guide a project to successful completion.

Determining the project scope is the first step in establishing the project’s schedule, budget, and resource allocation. Project management plans are made after the project scope is defined.

我希望现在您了解产品范围和项目范围。

现在是时候通过我们的商标学校建设示例向您解释这些概念了。

A Real World Example of Project Scope and Product Scope

You get a project to construct a school building. The client gives you their requirements, such as the size of the building, number of rooms, details of the playground, number of toilets, and paint color.

You start working on the project. You estimate the budget, develop the plan, and create a schedule.

After developing and approving the plan, you gather the team and move on to the execution phase. You bring workers to the site and start construction. You complete the school building and then verify with the client whether it is as per their requirements.

Once the client is satisfied, you hand the school building over to them, get the final payment, and the project is closed.

There are two parts to the above example.

In the first part, the client asks you to make a school building and gives you their requirements for it. The school building is the “product,” and the requirements are the “scope.” Therefore, the client gave you is the “product scope.”

在第二部分中，您可以在指定的时间和预算内构建教学建筑，并满足客户的所有要求。最后，您交付了产品。在这一部分中，您为建造教学建筑所做的工作是“项目范围”。

产品范围和项目范围如何监视和控制

The most important tool to monitor the product scope is the requirement traceability matrix. This ensures that all features of the project are produced, thoroughly analyzed, reviewed, and approved throughout theproject life cycle。

这也有助于管理产品的变化以及configuration management plan。

Project scope is monitored and controlled using variance analysis.

The Difference Between Project Scope and Product Scope

These are a few differences between project scope and product scope:

• Project scope is the work that delivers the product, while the product scope is the sum of all features, functions, and characteristics of the product.
• Product scope is oriented towards the “what” (functional requirements), while project scope is oriented towards the “how” (work-related).
• 产品范围是由业务分析师定义的，尽管项目经理可能会发挥作用。项目范围由项目经理完全定义。
• 项目范围的一个示例是构建桥梁，而其产品范围可能是其技术规格，例如长度，宽度和必须承受的负载量。

Summary

Product scope and project scope are covered in the scope management knowledge area in the PMBOK Guide. The product scope is the end result of the project, and the project scope is how you are going to achieve it. The project is defined according to the product scope. These are fundamental terms, and you must understand them. To complete the project, you must achieve these two scopes successfully. Product scope is the characteristics of the product, and the project scope includes all the work you will do to make the product.

Project scope is discussed in-depth, while product scope is covered briefly as it is not in the scope of the PMP Certification Exam. You will see many questions on your test from this topic, so understand these concepts well.
