Types of Requirements in IT Projects
Requirements analysis is a key stage in the design of IT systems, enabling the precise identification of the needs and expectations of both the client and end users. These requirements can be divided into several fundamental categories, each playing an important role in the software development process.
Business Requirements
These are the strategic needs of an organisation that an IT system is intended to address. They include goals such as improving operational efficiency, reducing costs, enhancing customer service, or increasing revenue. They define the business benefits the organisation aims to achieve through the implementation of a given system. Examples include shortening order fulfilment times or increasing the accuracy of sales forecasts.
Functional Requirements
Functional requirements focus on actions the system must be able to perform to meet business objectives. This includes specific functions and tasks such as user login, transaction processing, or generating reports. These requirements describe the system’s functionalities that are essential to meeting user needs and supporting use case scenarios. Examples include the ability to edit customer information or send automatic notifications about order status changes.
Non-functional requirements
Non-functional requirements pertain to the qualitative characteristics of a system and are just as important as its functionality. They include aspects such as performance, reliability, security, and usability. These requirements define how the system should operate and what quality standards it must meet. Examples include response time to a given query, maximum system load, or the level of personal data protection.
Performance | Performance refers to a system’s ability to process data quickly and handle multiple users simultaneously. Good system performance is crucial for user acceptance. |
Reliability | Reliability indicates how often a system operates correctly and how quickly it can recover after a failure. High reliability minimises the risk of downtime, which is crucial for critical business applications. |
Safety | Security involves protection against unauthorised access and safeguarding data from loss and breaches. Advanced encryption and authentication mechanisms are examples of meeting these requirements. |
Availability | Availability means that the system is ready for use whenever it is needed, which is crucial for real-time applications. This also includes ease of access to the system from various devices. |
Understanding and precisely defining these three categories of requirements is critical to the success of any IT project, as they impact all stages of the software lifecycle, from design to testing and deployment. All of these requirements are crucial for the success of information system design projects. They must be clearly defined in the requirements specification.

The process of gathering and documenting requirements
The requirements analysis document begins with information about the people who will use the software, followed by a brief description of the industry or company.
In an IT project, requirements gathering is a key stage that involves both software engineering and requirements management. This process includes meetings with the client to discuss both business and functional requirements.
Depending on the methodology, Use Cases or User Stories are created, which form the basis for further functional analysis.
Effective requirements gathering helps avoid misunderstandings and reduces the costs of potential corrections, while also preventing project scope creep. It is key to ensuring a high-quality product.
Techniques such as interviews, surveys, brainstorming, and prototyping are important as they help to understand the needs and expectations of stakeholders.
“Effective requirements gathering is the foundation of IT project success.”
Documentation of requirements is crucial throughout the entire project. It is used from the functional analysis stage all the way to implementation. Thanks to it, the project team can develop a system that meets the client’s requirements.
At Codari, we offer a free initial consultation to get familiar with your idea. If there is a need to clarify the details, we propose a workshop where we thoroughly discuss the scope and requirements of the project.
Constant monitoring and adjusting of requirements to changing business conditions is extremely important. Agile methodologies require continuous gathering and updating of requirements, ensuring high project responsiveness.
Tools and techniques used in requirements analysis
Requirements analysis in IT projects is a complex process that involves using various tools and techniques. Interviews and analytical workshops are essential as they help to understand user needs and gather important information.

Benefits of a Properly Conducted Requirements Analysis
Requirements analysis in IT projects is not only the foundation for effective system design and development but also the key to leveraging numerous benefits that can significantly impact the success of a project. A properly conducted analysis allows for a better understanding of the project scope, which in turn enables more accurate cost and timeline estimates, as well as resource optimisation.
Project Cost Optimisation
One of the main advantages of requirements analysis is its ability to precisely define the scope of work. This enables the project team to create a realistic budget, avoiding common pitfalls such as underestimating costs. Accurate budget planning minimises the risk of having to implement costly changes in the later stages of the project.
By understanding the client’s needs, it becomes possible to plan resources more effectively—both human and material. The project can be carried out using appropriately selected equipment and software, which helps prevent waste and improves execution efficiency.
Project Risk Reduction
Requirements analysis acts as an early warning system for potential issues and risks that could threaten the success of a project. By identifying these factors at an early stage, the project team has the opportunity to prepare appropriate preventive or mitigating actions.
Investing in a thorough requirements analysis results not only in cost and schedule optimisation but also in reducing project risk, which is a crucial part of requirements management and software development. It is the key to achieving success in IT projects.
According to research by the Standish Group, as many as 83.8% of IT projects face partial or complete failure. Only 16.2% of projects are successfully completed, meeting requirements for time, budget, and scope. This is why proper requirements analysis is an investment that delivers measurable benefits and increases the chances of successful project delivery.
The Most Common Mistakes in Requirements Analysis
In software engineering, requirements analysis is crucial. However, many IT projects struggle with errors during this phase, leading to issues and customer dissatisfaction.
One of the most common mistakes is the lack of prioritisation of requirements. Often, too many irrelevant requirements are added, leading to project overload. A misunderstanding of the end user’s needs is also frequently encountered.
Every year, many new products end in failure, which shows how challenging requirements management can be. It is important to set clear priorities and understand stakeholder expectations.
Requirements management requires an understanding of business objectives and user needs. It is important to focus on three main categories of requirements: business, stakeholder, and solution. Ensuring none of these are overlooked and maintaining hierarchy is essential.
“It is essential to avoid errors in requirements management to prevent, among other things, project chaos and resource wastage.”
Companies often make common mistakes, such as failing to regularly gather requirements. They often forget about stakeholders. Avoiding these mistakes increases the chances of success in software engineering.
Methods for Conducting Requirements Analysis
In IT projects, two main approaches are used: the Agile methodology and the Waterfall methodology. Each of them requires a thorough analysis of requirements, but they differ in how those requirements are implemented.
Agile Approach
In the Agile methodology, such as Scrum, requirements analysis is carried out iteratively. This means that requirements are defined on an ongoing basis. The team responds quickly to changes and delivers working parts of the system.
Scrum is based on principles, roles, and meetings that enable self-management in decision-making about work. In successive sprints, an increment of the system is delivered and tested by users.
Waterfall Approach
In the Waterfall methodology, requirements analysis is the initial phase of a project. After specifying the requirements, the technical design follows. The Waterfall methodology is characterized by a linear structure.
Each phase must be completed before moving on to the next. System testing takes place before deployment. The traditional methodology is distinguished by detailed project documentation.
The choice of methodology depends on the nature of the project and client expectations. Agile approaches work well in rapidly changing conditions, while the Waterfall methodology is better suited for projects with precisely defined requirements.
The Impact of Requirements Analysis on Project Success
Well-conducted requirements analysis is crucial for the success of an IT project. It allows for team organization and accurate workload estimation. It also aids in building test scenarios.
Requirements analysis reduces the risk of discrepancies between client expectations and the product. This, in turn, minimizes the number of issues during the acceptance phase.
Requirements analysis is the foundation of the software lifecycle in IT projects. It helps avoid errors and misunderstandings, supports requirements management, and increases the chances of success.
“Requirements analysis is the key to IT project success. It is the foundation upon which the entire software lifecycle is built.”
The requirements analysis process consists of several stages, such as gathering, documenting, verifying, and managing requirements. The main goals are to understand user needs and define the project scope.
Tools and techniques in analysis include interviews, workshops, document analysis, and prototyping. Use case diagrams are also important.
Requirements analysis is a challenge for teams. Key challenges include accurately understanding requirements and effectively managing changes. User involvement and regular updates to requirements are essential.
