Concept
System requirements define the essential specifications and conditions that a system must satisfy to function optimally, ensuring it meets user needs and business objectives. They serve as a foundational guide for system development, testing, and validation, helping to prevent project scope creep and ensuring alignment with stakeholder expectations.
Concept
User stories are short, simple descriptions of a feature from the perspective of the end user, focusing on the value it provides. They are a fundamental component of agile methodologies, guiding development by emphasizing user needs and promoting collaboration among team members.
Concept
A functional specification is a formal document that outlines the intended capabilities, appearance, and interactions of a software system, serving as a bridge between the conceptual design and the technical development. It ensures that all stakeholders have a shared understanding of the system's requirements and guides developers in building the product according to the agreed-upon features and functionality.
Concept
Scenario analysis is a strategic planning method used to make flexible long-term plans by evaluating the impact of different hypothetical future events. It helps decision-makers anticipate possible risks and opportunities, thereby improving the robustness of their strategies in uncertain environments.
Concept
An actor is a person who portrays a character in a performance, utilizing skills in voice modulation, physical expression, and emotional authenticity to bring scripted narratives to life. The craft of acting involves a deep understanding of human behavior and psychology, enabling actors to convincingly inhabit diverse roles across various media such as theater, film, and television.
Concept
A use case diagram is a visual representation of the interactions between users (actors) and a system, capturing the system's functional requirements. It helps stakeholders understand system boundaries and user interactions, facilitating communication and system design validation.
Concept
Unified Modeling Language (UML) is a standardized modeling language that provides a set of graphical notation techniques to create visual models of object-oriented software systems. It is widely used to help software developers visualize, specify, construct, and document the artifacts of a software system, facilitating better design and communication among stakeholders.
Concept
Requirements Engineering is the systematic process of defining, documenting, and maintaining the requirements of a software system to ensure it meets the needs of stakeholders. It involves collaboration, negotiation, and validation to manage changes and ensure the system's functionality aligns with business goals.
Concept
Interaction design focuses on creating engaging and intuitive interfaces that facilitate seamless communication between users and digital systems. It emphasizes user-centered design principles to ensure that digital products are both functional and enjoyable to use.
Concept
User-centered design is a design philosophy that prioritizes the needs, preferences, and limitations of end-users at every stage of the design process to create more effective and satisfying products. It involves iterative cycles of research, prototyping, and testing to ensure the final product aligns closely with user expectations and requirements.
Concept
Use case diagrams are a visual representation of the interactions between users and a system, delineating the various ways in which the system can be utilized to achieve specific goals. They serve as a valuable tool for capturing functional requirements and understanding the system's environment, facilitating communication among stakeholders during the development process.
Concept
Program specification is a detailed description of the software's behavior, functionalities, and constraints, serving as a blueprint for developers and stakeholders. It ensures clear communication, reduces ambiguity, and provides a basis for validation and verification throughout the development process.
Concept
Technical requirements are the specific conditions and capabilities that a system, product, or project must meet to ensure successful implementation and functionality. They serve as a foundational blueprint that guides development, testing, and deployment, ensuring alignment with user needs and project objectives.
Use case diagrams are like simple drawings that show how different people or things interact with a system to do specific tasks. They help us understand who does what and how everything fits together, just like a picture book tells a story with characters and actions.
Use case diagrams are like story pictures that show how people and things work together in a system. They help us understand what everyone needs to do to make something work properly.
Concept
Use case diagrams are like story pictures that show how people and things work together to do something special. They help everyone understand what needs to be done and who will do it, just like how a treasure map shows where to find the treasure and who will help find it.
