The full form of FDD depends on the context. It has multiple meanings, most commonly:
1. Feature-Driven Development (Software Development)
Feature-Driven Development (FDD) is a software development model that uses an agile approach. It focuses on building software by delivering working features in an iterative manner. This model prioritizes the development and delivery of specific features to the client, ensuring timely updates and functional software. Multiple sources confirm this meaning. For example, Byju's (https://byjus.com/gate/fdd-full-form/), GeeksforGeeks (https://www.geeksforgeeks.org/fdd-full-form/), and Unacademy (https://unacademy.com/content/gate-cse-it/fdd-full-form/) all define FDD as Feature-Driven Development within the context of software development.
2. Franchise Disclosure Document (Business)
In the business world, particularly franchising, FDD stands for Franchise Disclosure Document. This is a legally required document in many jurisdictions that provides potential franchisees with comprehensive information about the franchisor's business. This document outlines the terms and conditions of the franchise agreement, financial performance data, and other essential details. Investopedia (https://www.investopedia.com/terms/f/franchise-disclosure-document.asp) clearly explains the meaning and importance of the Franchise Disclosure Document. The California Department of Financial Protection and Innovation (DFPI) also references the FDD in their franchise application instructions (https://dfpi.ca.gov/regulated-industries/franchises/instructions-on-how-to-file-a-complete-franchise-application/).
3. Frequency Division Duplex (Telecommunications)
In the field of telecommunications, FDD stands for Frequency Division Duplex. This is a technique used in wireless communication systems to allow simultaneous transmission and reception of data using separate frequency bands. Aviat Networks (https://aviatnetworks.com/technology/understanding-fdd-vs-tdd-microwave-systems/) provides a clear explanation of FDD in this context.
4. Other less common meanings
While less frequently encountered, other definitions exist, including "Floppy Disk Drive" (as seen on Pinterest: https://www.pinterest.com/pin/fdd-full-form--830843831262707159/) and "Flue-gas desulfurization" (as per Quora: https://fullformsfunda.quora.com/What-is-the-full-form-of-FDD). However, these are less prevalent than the three primary meanings detailed above.
