Quality

Quality is something often discussed in project management, but many project managers struggle to understand it fully. Some organizations have a quality management system that sets out how to manage quality, but these systems are often limited to specific departments or product types, making them less useful for other projects.

Defining quality can be tricky, especially if you don’t know how to approach it. For example, if a sales manager requests a new sales system and you ask about quality requirements, they might struggle to answer. They might give you a list of features, but not provide clear expectations for quality. As project managers, it’s our job to ask the right questions to uncover these expectations.

If quality is not considered early on in the project, it’s hard to end up with a good, usable product. That’s why quality must be addressed from the start.

The good news is that PRINCE2 offers a simple and structured way to define, measure, and control quality throughout the project, ensuring a successful outcome.

Quality management in PRINCE2

The quality practice in PRINCE2 aims to establish a system that ensures products are fit for use and meet the required standards. It defines the PRINCE2 approach to guarantee that the products created during the project meet expectations and that the final product is usable as intended.

If quality is not as expected, the project will not deliver the anticipated benefits.

One of the PRINCE2 principles is product focus, which means that a project’s products should be clearly defined at the start or during a stage boundary process. This ensures that products are signed off (baselined) before development begins. The project plan and the stage plan should also include activities related to quality control.

The product description documents must include detailed quality criteria so all stakeholders have a shared understanding of the products to be created.

For example, if you are designing a new can opener, some of the quality criteria could be:

As you can see, the quality criteria provide specific and measurable details about the product.

The quality practice in PRINCE2 offers a method to define quality, carry out quality control, explain how to get approval, and manage quality throughout the project.

Definition of quality

Quality has its own terms, and these terms can mean different things to different people. The terminology used by PRINCE2 comes mainly from ISO 9000 standard. Just read these definitions for now; they will be explained further in this chapter.

The following are the definitions used in PRINCE2:

While project assurance is the responsibility of the project board, quality assurance is handled by the corporate or programme management. In short, quality assurance operates outside the project management team, while project assurance is part of the project team.

PRINCE2 approach to quality

PRINCE2’s approach to quality includes two key elements:

Quality planning begins with identifying all the products the project will control. PRINCE2 focuses on products from the start of the project, or as soon as they can be described and agreed upon, before any development begins.

The next step is to create a product description for each product. This description includes:

Quality control ensures that the planned quality methods are implemented and tracked throughout the project.

Part 1: Quality planning

Imagine you’re managing a project to build an apartment block for a mid-sized property developer. As the project manager, you need to collaborate with stakeholders like the customer, suppliers, and architects to define the quality expectations for the finished building and how quality will be controlled throughout the project.

Purpose

The following are the purposes of quality planning:

Without these discussions at the start, there can be misunderstandings and differing expectations about the project’s outcomes, leading to confusion and conflict.

Key questions to ask in quality planning:

Steps/concerns

The following are the quality steps/concerns involved in quality planning:

The customer’s quality expectations

It is normally not an easy task to extract the quality expectations of a product from a client, and the answers you get can be very vague, but this must be done and must be done as early as possible in the project so that they can be listed in detail in the project product description. In some projects the project product description may be updated during the project in the stage boundary process. This is fine, as long as each change goes via the change control process.

Some companies may be in a rush to get the product out or have budgetary issues, so they think they can save on quality. I have even seen projects where the funds were scarce at the start, but once the product was out and customers were having issues, lots of funds were available to start fixing. This approach is always a lot more expensive and harmful for users.

Some good questions to ask to get the customer focused on quality:

What percentage of features should work when product is launched, and what is the budget for critical issues (e.g., fixes, recalls etc.)? Tip: Notice their reaction when you ask. What will be the cost to the company if the product cannot be used as expected at the end of the project (e.g., fines, keeping old product in service, etc.)? Prioritizing quality expectations: Use MoSCoW. They should be prioritized, starting with what the client finds most important.

Prioritize technique: MoSCoW: This will be discussed later. It stands for 1) must have, 2) should have, 3) could have, 4) won’t have for now. You could also use: High, medium, low or not required but MoSCoW is better.

Example of the customer quality expectations for an apartment block project

List acceptance criteria

The acceptance criteria is a prioritized list of attributes the project product should have when complete. This is agreed upon between the customer and supplier in the first process – the starting up a project process, and is therefore linked to the project product description.

The following is an example:

Once the acceptance criteria list is complete, it will become part of the project brief. The acceptance criteria should also be prioritized using the MoSCoW technique.

Here is an acceptance criteria example for a website project:

The project product description

Don’t confuse the project product description with the normal product descriptions. The project product description is a description of the main product that will be produced by the project. The project product description is created in the starting up a project process and becomes part of the project brief. The product descriptions are created in the initiation stage as part of the planning activity.

The ‘closing a project’ process helps verify that the project has delivered what was expected and that the acceptance criteria have been met using the project product description. A good example of a project product description I like to use is the information provided for a laptop computer on a computer website. There will be an overview description, features, specifications and guarantee information. See the websites of Dell, HP, and Asus, for example. As you can see, it does not have to be 100 pages but more like 2 to 4 pages.

Acceptance method

Quality management approach

A quality management approach is a document and a plan of action that defines the quality requirements and the quality control method for all the products in the project. This document also confirms how the quality systems and standards from the customer and supplier will be applied to the project. In other words, the quality management approach document defines how quality will be done in the project.

This document is created at the initiation stage with the other strategy documents and becomes part of the project initiation documentation.

The quality management approach answers the following questions:

Product descriptions

The product descriptions should be created for all the products as part of the planning activities and before the project plan can be completed. This is not always possible in each project; therefore, product descriptions may be created or updated in the stage boundary process, and the product descriptions will be agreed upon and baselined before development starts.

The typical content of a product description is similar to the project product description. The contents are as follows (again, notice how much quality information):

Quality register

The quality register is a diary of the quality events that take place during the project, such as workshops, reviews, testing and acceptance. At first, the quality register will be empty and the project manager will get most data from the plans and product descriptions. Many project managers use a spreadsheet as a quality register.

The quality register makes it easier for the project manager to follow up on quality during the project, as they can check whether the actual target review date and actual approve date columns are filled in or not. This allows the project manager to control quality.

Full quality audit trail (quality history): As the quality register contains all the quality activities and is continually updated during the project, it provides a full audit trail for quality.

Part 2: Quality control introduction

What is quality control? Quality control is carrying out the activities to control quality as defined in the quality management approach. There are three parts to quality control, and I will explain each of them:

Quality planning, quality control, accepting products

The quality register is used to:

  1. Plan quality,
  2. Control quality
  3. Provide a history of quality activities in a PRINCE2 project.

Supporting techniques

Understanding the quality techniques and their timing, location, and resources is essential for project planning. While many quality techniques exist, the most common ones in project contexts are:

Roles and responsibilities

Here are some of the responsibilities relevant to the quality practice.
