Project scope statement

Abstract

Defining a project scope statement is an essential part of any project. It is an output of the define scope process and used to identify the main deliverables of a project along with the key milestones, the boundaries, assumptions, and constraints. This statement documents also the responsibilities of each member of the project team and procedures for verifications and approves of completed work. Both the project team and all of the stakeholders have to agree with all of the terms suggested in the scope statement before the actual project work begins . Even though the project scope statement is supposed to head the project in the right direction the situation can change as the project progresses. The changed situation has to be assessed on all aspects of the project and necessary changes have to be proposed to the project scope statement. The scope statement needs to be adjusted if the changes are approved . A well-written scope statement is an important part to achieve a successful project and the six main aspects which a good statement should include are a product scope description, acceptance criteria, deliverables, project exclusion, constraints, and assumptions. These aspects will be discussed in more details in the following article, along with general guidelines of how to write a project statement, a concept called scope creep and at last, the limitations and advantaged of writing a project scope statement will be discussed .

Introduction

Project Scope Management

Figure 1: Project scope management processes and their tasks, with guidance from the PMBOK® Guide

As outlined in the abstract, the project scope statement is an output of the defined scope process, which is a part of the project scope management process. The project scope management process refers to the set of processes required to ensure that a project includes all the necessary work, and just the amount of work necessary, to successfully complete a project. It is primarily concerned with defining and controlling what is or what is not a part of the project. Therefore the project scope can be defined as the work that must be done to deliver a product with the specified features and functions, according to the PMBOK® Guide . In Figure 1 the six major processes of the project scope management can be seen and their tasks description.

Each of these six processes interacts with each other and each process usually affects the next process which comes after the other. The first process in the project scope management is the planned scope management process. This process formally authorizes a new project and creates the scope management plan that records how the scope of the project will be managed. The planned scope management process influences the defined scope process, which develops the project scope statement, by linking the output of it to the input of the define scope process. Between these processes is an important process which is referred to as collecting requirements process. This prosses determines, documents and manages the project requirements that reflect on stakeholders needs to meet project objectives. These requirements selected to be part of the scope baseline are generally decided by the project governance, the project sponsor, the project management team, the project's customer and inputs from different stakeholders, who are considered to be important.

The identification process of who the project stakeholders are is an important early step in the scope planning. Project stakeholder can consist of persons or organizations that are actively involved in the project or if their interests may be affected by the project. These stakeholders can be, for instance, sponsors, customers, suppliers, and shareholders. It is important for the project manager of a project to set proper expectations with their stakeholders at the beginning, to ensure that no misunderstandings can appear later on. These expectations can be about how the requirements or the scope of the project is managed, controlled and verified and these expectations are one of the elements in the project scope statement that needs to be well defined. The documentation of the requirements will be discussed further in the next section of the define scope process where it is an input and an essential element of the involvement of establishing the project scope statement.

Define Scope

The define scope process is the third process of the project scope management and it consists of developing a detailed description of the project. The main benefits of establishing the detailed description are that it provides a basis for future project decisions and develops and confirms a common understanding of the project scope among the stakeholders. In addition to containing an accurate description of the project, it also includes which of the requirements from the requirement document, developed in the collect requirement process, are selected to be the final requirements of the project scope. To select and decide what is suppose to be part of the project description or the project scope statement are different management tools and techniques applied. These tools and techniques are differently balanced since each project is unique and the scope of a project can be differently planned.

Project scope planning begins with the initial inputs of a project description, a project charter, a definition of the constraints and assumptions. 

Each project is unique and the scope of a project is differently planned by different balanced tools and techniques. These tool and techniques are applied to get a better understanding of a project and they include product analysis, cost and benefit analysis, alternatives identification and expert judgment.

Product analysis involves in examining some of the product features and includes techniques such as product breakdown, analysis systems engineering, value engineering, value analysis, function analysis and quality function deployment. The cost and benefit analysis is a technique used to compare the total cost of the project with its benefits to make suitable decisions on what alternative investments are the right ones. The alternative identification technique is an evaluation of different choices available to achieve a particular project management objective, they are general management techniques for example brainstorming and Delphi technique. The expert judgment is a technique in which judgment is made based on a certain set of criteria and expertise that has been acquired in a certain knowledge part or product part. This expertise can be provided by any person or group with specialized knowledge, skill or education .

Inputs:

1. Scope management plan -
2. Project charter -
3. requirement documentation -
4. Organizational process assets -

Tools and techniques:

1. Expert judgment -
2. Product analysis -
3. Alternatives generation -
4. Facilitated workshops -

Outputs:

1. Project scope statement -
2. Project documents updates -

After applying some of these techniques to get a more detailed description of the project and analyze the project, the project scope statement can be documented along with other outputs of the scope planning, see Figure 3. Further information about what requirements need to be documented in the project scope statement will be discussed in the next section.

Practical Guidelines

Practical guidelines of how to write a project scope statement and the four main aspects of the project scope statement will be discussed in more details.

• Project justification
• Project product
• Project deliverables
• Project objectives

Scope Creep

Discussion about what scope creep is and how it is connected to the project scope statement.

Limitations

There are few main limitations of the project scope statement and they will be discussed in this section, both strength and weakness.
