It's no secret that you need to have clearly defined processes with frequent checkpoints and checklists for a project to succeed. But what does this process look like in practice? What work needs to be done, and how can we effectively measure our success? The answer is with a functional specification document. This document is one of the most important documents in any project or software development process (agile or waterfall). It's a document describing what the end-users want the system to do and not how it works. It includes input, output, control logic, storage, data handling, and security requirements.

It is a document that describes what the end-users want the system to do and not how the system works. It includes projects scope , risk and assumptions, product overview, use cases , requirements, system configuration, non-functional requirements and error reporting. It is a document that specifies the functionality of a software system. It typically includes the specifications for all or most of the following:
Functional specifications can be created using a variety of techniques. These techniques can include:

It is the best way for stakeholders to understand the end product without knowing how it will work. It is a set of instructions that explains how a system should be used and what it should do. It is usually written by the person who designs the system.
The functional specification document is essential because it helps ensure that a system can be used in the way initially intended. It also helps ensure that the system will work with other programs and systems that may not have been considered during design.
Functional specifications may be used to: A functional specification document is typically written by a user, commonly the system's designer. It includes system goals and purpose, expected use cases, requirements for data input and output files, any external devices that need to be hooked up with the computer(s), and how much computing power is needed for calculations.
The person who creates the varies depending on the company's needs. The technical writer or product manager might work with developers to create a specification for a new program or features for an existing one.
In some cases, there are two people involved in creating this document, the product owner and the developer. The product owner is responsible for ensuring that the functional specifications make sense and that they meet user needs. The developer is responsible for defining a detailed description of how the system will be built with a complete analysis of all requirements.

It is a technical document that describes what the end-users want the system to do and not how the system works. It's a document that includes information about the projects scope ,risk and assumptions, product overview, use cases, requirements, system configuration, non-functional requirements and error reporting. It should contain:
Project Scope :The goals, deliverables, functions, tasks, costs, and schedules associated with the project. It includes a detailed description of what is expected to be done, delivered and completed within the specified project schedule and budget.
Risks and Assumptions : Risks and assumptions are all potential variables and factors that can significantly affect the functional design of a product. A detailed analysis of risks and assumptions is necessary to avoid potential roadblocks and ensure smooth execution of the project.
Product Overview :This is where you describe how your product solves a specific problem for your target audience. The product overview is typically depicted through various visual tools such as sitemaps, screen flows, and wire frames, which help to illustrate the user experience and provide a better understanding of the application’s key features and functionalities.
Use Cases :Provide a comprehensive context for functional requirements, by placing them in the context of a user action. This approach is critical in effectively demonstrating the application’s functionality from the user’s perspective, providing a clear understanding of how the user interacts with the application and the outcomes of their actions.
Requirements : C ritical product’s features that answer the question: what does your product do? They are an integral part of the product development process, and must be carefully considered in order to ensure that the final product meets the needs of its end users.
System Configuration - These are the steps required to configure the product. For example, when setting up user accounts, system configuration includes defining login information, selecting appropriate security options, and setting user interface and preferences.
Non-functional Requirements - Documentation may list useful product features that are not considered part of the core functionality. Non-functional requirements are not essential for a product to work, but they play an important role in determining its overall quality and usability.
Error Reporting - Describes how the product handles errors or exceptions. What messages and options should the user interface (UI) display to end users? These messages should be clear and concise, and contain enough information to help users understand what is happening and what actions they can take to resolve the issue.

A functional specification document describes what the end-users want the system to do and not how the system works. For example, you might create a specification for an app that helps people find public toilets in a city. It would include information about the input (such as GPS location) and output (public toilet location). Functional specs are often used in agile or waterfall development processes. To create a functional specification document, there are a few steps you need to take:
