How To Be A Great Business Analyst – “Why is business analysis so important?” – In fact, some software projects may run without business analysis, but it may take an unexpectedly long time.
In this article, I explain the role of a business analyst at each stage of a software project and share thoughts on how to become a successful business analyst.

Carnegie Mellon University (CMU), considered the best in IT specialist preparation, compiled the following statistics on the influence of business analysts on projects:

Soft skills are essential for an IT business analyst as such work involves a lot of communication with both the client and the development team. Here’s a list of soft skills that I consider important:
For those at the beginning of the BA career path, the most optimal way to acquire soft skills is real-life practice. Theoretical knowledge can be useful, and some of the books I recommend for gaining that knowledge are:
Presale is the pre-contract stage of the project. This is the time when the client explains the business idea to the project team, asks questions, and decides whether the company is meeting expectations.
The role of a business analyst at this stage is to obtain high-level requirements, find out who your clients are, understand their domain area, and forecast BA activity on future projects. There are also sales managers and technology experts who negotiate with clients, suggest optimal technology solutions, and provide estimates for the development phase.

RFP – A Request for Proposal is a document provided by a potential client or sales manager based on information received from the client. The document should contain a brief description of the business idea, key functions and features of the future product, requirements and budget.
If the information provided does not represent the full picture, and we are unable to answer most of the questions above, it is advisable to ask the client additional questions. Here’s an example:
Business analysis like any other project activity must be estimated. This is necessary for both the client for budget planning and the company for better team allocation. There are two common estimation methods used by business analysts:
Estimated ROM (Rough Order of Magnitude) which is especially suitable when prospective clients are making decisions about their next steps. The estimation error varies from -25% to +75%.

Definitive Estimates, which are often requested at the development stage. The error varies here from -10% to +10%.
Design – If a design exists, the BA expert can find the unique screens and set the time required for the description of each screen. – If there is no design, the BA expert can divide the project into modules and estimate the unique features in each module.
Communication time It is important to consider the time spent communicating with the client and team when clarifying requirements. A good practice is time going into separate tasks which helps compare estimates and actual time spent.
Risk BA Expert allocates 10-15% of the total estimate for unforeseen situations such as clarification of unclear requirements or long waits for client response.

The main goal of the UI/UX Design and Prototype stage is to create a visual representation and user interaction for the future product. The efficiency of the results depends on how well a designer and business analyst understands the needs, capabilities, and limitations of the user. It is equally important to consider the project’s business goals and objectives while creating the UX/UI part of the future product.
The role of a business analyst is to focus on the general thrust of a project and conceptually consider the UX design before creating the UI.

BA artifacts are wireframes, mockups and prototypes. Depending on the project, the business analyst may create these materials together with the UI/UX designer or on their own.
Wireframes are low-level images of a product interface that schematically show its structure and define the placement of images, text, buttons, tabs, headers, footers, etc. This artifact is not a ready made design that can be changed or deleted. This is a rough visual representation that should clearly reflect the logic of the future product.
A mockup is a more detailed visualization of a future product. They contain many color schemes, visual styles, and fonts. These artifacts may be submitted by designers and business analysts, depending on the case.
A prototype is a high-level presentation of the final product interface that presupposes a simulation of user interactions. This is a clickable product prototype that fully demonstrates what user actions lead to what output.

It is important to understand that the efforts of business analysts and designers must work together. While the business analyst is in charge of the business logic of the future product, the UX/UI designer carries out user expectations through the visualization method.
Software development is one of the most time-consuming and budget-consuming stages during a project. It requires attention to detail and analytical skills. Clear and detailed specifications enable optimization of the development process and minimize the need for on-the-go changes.
The role of a business analyst here is to describe the behavior of software systems, create and manage project documentation, and support requirements relevance. The BA workflow here may differ depending on the project. Generally, business analysts choose one of the following two schemes:
User Stories are short descriptions of the functionality section from a user perspective, where the user role consists of not only end users but also administrators, editors, moderators, writers and others. The template is as follows:

User Stories often come with acceptance criteria that serve as an expected output metric. Simply put, it is a statement that describes what exactly should be done to meet the needs of the user. As an example:
Use Case is a description of how users (actors) will interact with the system in the future. It describes how the system is expected to behave in response to certain actions from the user’s side.
A scenario is a sequence of interactions with the system intended to achieve user goals and generate a response to user actions.
The next big thing in business analysis is diagrams. In general, we make Use Case and BPMN diagrams. The main purpose of this diagram is a visual description of the behavior of the system that can be understood by both the client and the software development team.

Use Case Diagram is a visual representation of the expected system behavior. It is a modeling technique that helps business analysts design concepts of system behavior from a user perspective, and then translate them into functionality solutions and development priorities. Here’s an example:
A BPMN diagram is a visual representation of a business process workflow. BPMN functions as a Business Process Modeling Notation which is a standard modeling language that can be understood by most non-technical stakeholders and software developers.
Non-functional requirements (NFR) describe software performance quality metrics. Simply put, the NFR document contains a direct description of the software components that should ensure:
Business analysts typically use the ISO 25010 quality model in terms of software development requirements. An example of an NFR might sound like this:

A Software Requirements Specification (SRS) is a set of documents that contains a complete description of the features, behavior, environment, and objectives of the software being developed. It may have any format and contain any type of requirements, depending on who it is created for, development methodology, project standards, etc. The following is an example of an SRS component:
As for the tools used to create SRS documentation, we usually use Confluence, as it helps create well-organized page hierarchies and uses macros and formatting features. But it is also possible to create SRS in Google Docs.
The role of the BA expert here is to provide consultation and context for any part of the requirements that helps understand how the system is expected to work.
The business analyst should also update the requirements if they change and monitor their relevance. When the project team presents the demo to the product owner, the business analyst also participates directly in this process.

In the release phase, the business analyst manages the implementation of the expected functionality, provides support to the project team, and prepares the relevant SRS documentation for transfer to the product owner.
In addition to the main BA activities during the project cycle, it is also good practice to make a SWOT analysis and Gap analysis. This type of analysis helps compare current results with planned results, and find out if the product was developed according to the right roadmap. They’re not 100% necessary, but in some cases, they can help keep the project on track.
SWOT analysis in BA practice can be used to evaluate the current state of a project or product. It is used to find out what the real situation is from an external perspective. It is a framework that includes the following evaluation attributes:
Gap analysis is the discovery of possible goals by evaluating whether the currently developed functionality meets the business requirements or not. Gap Analysis involves four general steps:
