Functional Analysis Decomposition And Composition (FAD&C)

   Functional Analysis Decomposition And Composition (FADAC) is a systems engineering technique that is used to break down a complex system into smaller and simpler components. This is done by identifying the system's functions and then decomposing each function into its constituent parts. The FADAC process can be divided into three main phases:

   1. Functional Analysis - This phase involves identifying the system's functions and their relationships to each other.

   2. Decomposition and Composition - This phase involves breaking down each function into its constituent parts.
   Evaluate alternatives: Performance, costs, assembly considerations, and customer satisfaction with the chosen alternative.
   The overall considerations will be evaluated during the decomposition and composition process.

   3. Composing the parts back together to form the original system including interfaces and communication required between all the breakdown parts.

   FADAC is widely used in the initial sprints of Agile-Scrum projects.

   The author of Functional Analysis Decomposition And Composition (FADAC), a system engineering design methodology, is Gideon Koch.
   FADAC is a top-down design methodology that decomposes a system into its functional blocks and then composes those blocks into a working system. It is a well-established methodology that has been used in a variety of industries, including aerospace, automotive, and defense.

Overview

Here are some of the key features of FADAC:
   • It is a top-down methodology, which means that it starts with a high-level view of the system and then decomposes it into smaller and smaller blocks.
   • It is a modular methodology, which means that the functional blocks are independent of each other. This makes it easy to change or upgrade individual blocks without affecting the rest of the system. It is well design to provide tasks for Agile projects.
   • It is a reusable methodology, which means that the functional blocks can be used in other systems. This saves time and money in the development process.
   • It is a well-documented methodology, which makes it easy to learn and use.
   The FADAC process can be used to design, develop, and maintain complex systems. It is a versatile technique that can be applied to a wide variety of systems, including software systems, hardware systems, and organizational systems.

   When you design your product, you need to have these topics in mind:
   > Directed by requirements
   > Step by step process
   > Evaluate alternatives
   > Risk assessment

Process

1. Top-down design
   1.1 Decomposition of the product functionality into basic blocks that perform what is required.
   1.2 Evaluate alternative (buy vs. develops)
   2. Bottom-up Composition
   2.1 Prepare a sketch diagram of the communication between all the product modules.
   2.2 Check which module performs what during every function
   3. Evaluate your solution
   3.1 Time to market (prepare a Work Breakdown Structure and a Gantt Chart - part of the FADAC method)
   3.2 Competitive analysis

   The following is an example of how the FADAC process can be used to design a software system:
   1. The first step is to identify the system's functions. In this case, the system might have the following functions:
    User authentication
    Data storage
    Data retrieval
    Data processing
    User interface
   2. The next step is to decompose each function into its constituent parts. For example, the user authentication function might be decomposed into the following parts:
    Username and password validation
    Session management
    Role-based access control
   3. The final step is to compose the parts back together to form the original system. In this case, the software system would be composed of the following components:
    A user authentication component
    A data storage component
    A data retrieval component
    A data processing component
    A user interface component
