vaatimustiedosto

A vaatimustiedosto, also known as a requirements document or specification document, is a formal document that outlines the functional and non-functional requirements for a software system, hardware device, or other product. It serves as a blueprint for the development team, providing a clear understanding of what the product is expected to do and how it should perform.

The primary purpose of a vaatimustiedosto is to ensure that all stakeholders, including developers, testers, and clients, have a shared understanding of the project's goals and expectations. It helps to prevent misunderstandings, reduce the risk of scope creep, and improve communication among team members.

A well-written vaatimustiedosto typically includes the following sections:

1. Introduction: Provides an overview of the document and the project.

2. Functional Requirements: Describes the specific behaviors and functions that the product must perform.

3. Non-Functional Requirements: Outlines the performance, usability, and other quality attributes that the product must meet.

4. Constraints: Lists any limitations or restrictions that must be considered during development.

5. Assumptions and Dependencies: Identifies any assumptions made during the requirements gathering process and any dependencies on external factors.

The vaatimustiedosto is usually created during the early stages of a project and is subject to change as the project progresses and new information becomes available. It is essential to maintain the document throughout the project lifecycle to ensure that the development team remains aligned with the project's goals and requirements.
