Validating requirements is a crucial aspect of business analysis for professionals pursuing the PMI Professional in Business Analysis (PMI-PBA) certification. It is a process that ensures the requirements of a project are complete, accurate, and aligned with the project’s goals, objectives, and value proposition. There are numerous tools and techniques, ranging from documentation review and prototypes to demos and other validation methods, which can be employed to ensure this.
1. Documentation Review
Documentation review is the primary tool used for validating requirements. It involves scrutinizing various documentation related to a project, such as project plans, feasibility studies, requirement specifications, process maps, and user manuals, among others. The goal is to discern the accuracy of the presented requirements and to ensure that they align with the project’s objectives.
To make the documentation review process more thorough and effective, business analysts often utilize advanced document technologies, such as text analytics, which allow for more comprehensive and rapid document review.
2. Prototyping
Prototyping is an interactive tool that allows stakeholders to provide feedback on the proposed system before it is fully developed. Its objective is to validate the requirements by providing a model of the system that helps users understand how the finished product will work. By refining the prototype through several iterations, stakeholders can ensure that the final product meets all their requirements.
Prototyping is often used in combination with other validation methods like focus-group reviews and usability testing, which further assures that all project requirements are met.
3. Demos
Demos are live presentations of the systems and/or modules that have been developed. They provide the stakeholders with a first-hand experience of how the system will function, allowing them to check that their requirements are accurately and fully accounted for. Demos can be used to validate the interface, workflows, functionalities, and features of the software solution.
4. Other Validation Methods
Other validation methods include inspection, walkthrough, and testing.
- Inspection: This involves a formal review process where a team of experts ‘inspect’ the requirements document for possible defects and inconsistencies.
- Walkthrough: This is an informal meeting where the author of the requirements document explains it to the stakeholders or a selected review team. It helps to gain consensus on the requirements and to resolve any possible ambiguities.
- Testing: This is applied to the developed software to verify that it fulfills the requirements laid out in the documentation.
Example of a Requirements Validation Process
Suppose we are working on a project to develop a mobile app for an online store. Let’s look at how the validation methods may be used in this context.
a) Documentation Review: The business analyst will review the requirements document, which includes an outline of the app features, the intended user interface, how users can add items to the cart, etc.
b) Prototyping: A mock-up of the app is created, where stakeholders can explore and provide feedback on the interface and functionalities.
c) Demos: Live presentations of certain app functionalities are given to stakeholders, like how to create an account, add items to the cart and make purchases.
d) Other Validation Methods: Inspecting the requirement document for any missing or ambiguous requirements, walkthrough of the requirement document with the stakeholders for better understanding, and testing any developed modules to ensure they match requirements.
The choice of the validation method often depends on the project context, available resources, stakeholder preferences, and the nature of the requirements. A combination of these tools and techniques tends to offer the best outcomes during the requirements validation process.
