How to make a great functional specification
- by sfrj
I am going to start a little side project very soon, but this time i want to do not just the little UML domain model and case diagrams i often do before programming, i thought about making a full functional specification. Is there anybody that has experience writing functional specifications that could recommend me what i need to add to it? How would be the best way to start preparing it?
Here i will write down the topics that i think are more relevant:
Purpose
Functional Overview
Context Diagram
Critical Project Success Factors
Scope (In & Out)
Assumptions
Actors (Data Sources, System Actors)
Use Case Diagram
Process Flow Diagram
Activity Diagram
Security Requirements
Performance Requirements
Special Requirements
Business Rules
Domain Model (Data model)
Flow Scenarios (Success, alternate…)
Time Schedule (Task Management)
Goals
System Requirements
Expected Expenses
What do you think about those topics? Shall i add something else? or maybe remove something?
