It has been said that a picture is worth a thousand words. For people, it is much easier to comprehend abstract information by looking at it, visualizing it in their mind, and thus, seeing the whole picture.

According to Statista, the value of the global data visualization market is projected to reach $7.76 billion in 2023, growing by about 9% yearly. This fact alone proves data visualization tools are an effective means for providing better perception and cognition of information.

In this piece, Andersen’s experts in business analysis will describe the types of visual documents prepared by a Business Analyst, as well as the contributions of analyzing business requirements and their subsequent graphical representation to a project’s success.

A brief recap

In the previous part of this article, Andersen’s experts in business analysis have already discussed one of the key responsibilities of a Business Analyst on a project, namely analyzing business requirements and documenting them.

Statistics and research findings prove the key role of properly documented requirements for meeting customers’ expectations regarding software functionality. If you want to avoid a costly and time-consuming redesign and rework, you must ensure that the expert who draws up and maintains business analysis documentation is present on your project.

Analyzing business requirements and documenting them is crucial for successful software delivery and offers you the following benefits:

  • better project traceability;
  • efficient troubleshooting;
  • consistency of requirements.

The major Business Analyst’s artifacts that this specialist delivers and that we have covered so far are a meeting agenda, follow-up email, Vision & Scope document, Software Requirements Specification, user stories, user story maps, and use cases.

In this piece, Andersen’s Business Analysts would like to dig into the topic of requirements visualization. Read on to learn what visualization artifacts Business Analysts deliver to customers and the project team, and why visualizing software functionality is crucial for your project’s success.

Three reasons why you should visualize the requirements

A rule of thumb states that the more complicated software architecture is, the more detailed and structured the visualization of every part of the system should be. Functional requirements in business analysis that are presented graphically communicate some types of information more efficiently than text. For example, it’s easier to describe a system’s data flow with diagrams and the interface details with wireframes and prototypes, rather than writing dozens of text documents for this purpose.

Below are several benefits that proper visualization of requirements brings to a project:

A holistic view of the system’s functionality

Indivisible software requirements contained in a Business Analyst’s documents that describe the system’s design, the testing process, and work management are called atomic requirements. Along with the undeniable benefits that well-documented requirements bring to a project they have a serious drawback. Namely, they prevent shareholders from embracing the system as a whole and understanding the designed business logic and software functionality clearly. All that customers see is a broad to-do list with no idea how everything is going to be implemented.

The requirements visualized by a Business Analyst allow customers to see the scale and complexity of a product and its functionality. This is extremely important for accurate estimation of budget and timelines. Additionally, the product’s graphic representation marks the first step in transforming rough requirements into a well-designed solution with a detailed plan for its implementation.

Requirements verification

By visualizing requirements, Business Analysts are able to identify errors, missing requirements, and lacking coverage of the designed functionality with use cases.

There always exists a strong temptation to start the development process right after the requirements are elicited and documented. However, in the early stages of a project lifecycle, the concept that is being designed is full of flaws and inaccuracies due to the lack of user and customer feedback. In addition, the development team might not understand the product goals clearly.

The aim of visualizing the Business Analyst’s functional requirements is to construct a completed piece of business/user flow with all possible scenarios involved. This helps a Business Analyst identify unaccounted aspects of the functionality, ensure logical consistency of the designed model and the exhaustive nature of the documentation where all the requirements and use cases are described.

Quick feedback from stakeholders

According to the Agile approach toward custom software development, the customer and the development team need to interact closely so that efficient cooperation can be ensured and a valuable product can thus be delivered. Agile projects necessitate constan
