![]() ![]() Should be crisp, non-ambiguous and written in non-technical language.Deal exclusively with the functionalities and features and do not contain any technical requirements within them.Are written from the perspective of the system and not from the viewpoint of the user (remember the prefix “The system should ….”).only states ‘what’ the system is expected to do/perform and not ‘how’ the system is expected to do that (that’s in Application design document).Are given by the users/business stakeholders.The system should provide weekly/monthly selling trend details by analyzing past dataĬharacteristics of Functional Requirements.The system should reduce wastage of raw materials while improving cost savings.Only authorized persons will have access to the system and the role of the administrator shall be assigned to only one person at a time.Maintain the balance between too much and too little inventory.The system should provide alerts when an item in the inventory goes below a threshold level.The system should maintain tracking of sales of products and inventory levels.The system shall save the details of the goods available in the warehouse by dividing them into different categories.The functional requirements for the ‘Inventory management system’ will be: This requires better management at his manufacturing plant and thus Rob wants an ‘Inventory management system’. ![]() Now, Rob wishes to expand his products range and produce baseballs and footballs as well. Let’s assume Rob is the owner of RobRolls, a company which manufactures basketballs. Since functional requirements define the features and capabilities expected from the solution, they are sometimes called as Solution Requirements.įunctional requirements are generally written in the format “system shall do/perform ”. For instance – business rules, processes and flows, authorization and security needs, legal/compliance requirements. However, since functional requirements are expected to describe all the ‘functionality’ related aspects of the solution to be developed, they are usually not as simple as the examples above and consists a lot within themselves. ‘Pen’ – Should be able to apply ink on a surface.‘Key’ – Shall be able to lock and open a door.Let’s try to understand it better with some simple examples. What are Functional Requirements – Quick Overviewįunctional Requirements describes the functionalities, capabilities and activities a system must be able to perform and they specify the overall behavior of the system to be developed.Īt a basic level, they specify what any service/product should be able to perform. Yes, they should and are called Functional Requirements! However, for the project to succeed, shouldn’t the features and functionalities expected in the system uniquely identified? Any software/application development project ends up in the creation of a unique product or a service. ![]()
