What is FRS document?
●What is FRS? FRS stands for Functional Requirements Specification. This document describes the functional requirements of a product. FRS documents are written using a specific format and should be reviewed before any project begins.
●FRS stands for Functional Requirements Specification. It is a document that contains the functional requirements of the product being developed. These requirements are broken down into smaller pieces called user stories. A user story is a brief description of what the end user wants to accomplish using the system.
●The FRS document is created after the project scope has been defined and before any coding begins. It is a living document that changes as the project progresses. You may need to add or remove some user stories as the project evolves.
Why FRD documents are necessary:
- To ensure that the product meets its intended purpose.
- To provide a basis for comparison between different products.
- To avoid wasting time and money on projects that do not meet their goals.
- To make sure that the product is built according to specifications.
- To help keep track of changes to the product over time.
- To ensure that no mistakes are made when building the product.
- To ensure that the product is built correctly.
- To allow for future changes to the product.
- For quality control.
- For customer satisfaction.
- To ensure safety.
- To ensure compliance with regulations.

How to write the FRS document?
1.Introduction
The FRS (Functional Requirements Specification) document is a document that describes the functional requirements of a product. It includes the description of the system’s functionality, its purpose, and how it should work. A good FRS document helps the project team understand what they need to build and how it should work, and it provides a basis for defining the scope of the project.
2.Functional Requirement Statement
A functional requirement statement (FRS) is a short sentence that states the function of the system. An example of a functional requirement statement would be “the system shall provide access to the user’s account information”.
3.User Stories
User stories describe the use cases of the system. Each story contains a brief description of a specific task performed by the user of the system. An Example of a user story might be “as a customer I want to view my order history”.
4.Use Cases
Use cases are a way of describing the interactions between users and the system. In each use case, there is a user who performs some action and the system responds. An example of a use case might be “As a customer, I want to view my account balance”.
5.Business Rules
Business rules are guidelines that help ensure the integrity of data. For instance, if a customer enters his/her credit card number, then the system must verify that the number entered is valid before processing the transaction.
6.Acceptance Criteria
Acceptance criteria define the quality attributes of the system. These are the characteristics that make something acceptable. Examples of acceptance criteria might be “the system must be able to display the current date and time” or “the system must allow customers to view their orders”.
7.Technical Specifications
Technical specifications are the technical details of the system. They may include things like hardware configuration, operating systems, programming languages, etc.
Examples of functional requirements may be:
- Requirements for auditability and audit trails.
- Certification requirements.
- The necessary levels of authorization.
- Easy of interfacing with external users.
- Output reports to be provided.
- Ability of make corrections, updates to inputted data.
- Regulatory requirements (also potential non-functional requirements).
- Ability to restrict users to functional performance levels.
- Ability to generate and retain user and performance histories.
- If there is an ordering element, then the system may be required to generate an order i.d. which will carry through to all related activities and allow full historical and status search based on the specific i.d. number.
Examples of non-functional requirements may be:
- Capacity of the system.
- Associated documentation.
- Regulatory requirements.
- Requirements for future extension of the software.
- Requirements for disaster recovery.
- Portability of the software.
- Quality expectations.
- Level and integrity of security.
- Associated with security may be privacy requirements.
- Response times to user inputs and system outputs.
