Identify Functional Requirements

Input - Anything the user has to enter at the keyboard. Any data read in from a File

Process - What does the program have to do/calculate/search/compare

Output - What is displayed to screen or written to an external file.

SDD Analysis Overview

Use Design Notation

Pseudocode
Structure Diagram

Could include:

Finding Min/Max
Count Occurences
Linear Search
Specific function (validation, substring etc.)

Standard Algorithm Design

Data Flow Table/Diagram - Pass in/out parameters

Code your solution using Python

Past Example Solutions

Classwork - Example Programs

Test your solution using Normal, Extreme, Exceptional Test data

Trace Tables

Debugging Tools

When Evaluating, it is IMPORTANT that you evaluate your own code.
You could be asked to evaluate:

Maintainability
Efficiency
Fit for Purpose
Robustness

Web Development

Identify Functional Requirements
The page should include...

The website includes information about the history of Marr College.
The website includes a form for new members to register.

Identify End-User Requirements- VERB

Users can READ information about the history of Marr College.
Users can TYPE details into a form to register as a new member.

Requirements Example

Draw a wireframe

Draw a navigation map

Positioning & Layout

Horizontal Nav Bar

HTML Forms

JavaScript

There are a number of tests you should carry out on your website to ensure that it meets the functional requirements.

Input validation:

check that every field in a form has the correct validation by trying to get every field on the form to accept incorrect data. Normal Extreme Exceptional

Links and navigation:

test the navigational bar links take you to the correct pages
test all external links work correctly
test that all pages can get back to the home page
test all internal links work correctly
test to check if there are any orphan pages (pages that are not linked to any others)

Media content:

ensure that the text, graphics and video display correctly and in the position in which it was designed to appear

Compatability Testing

Evaluate 'Fit for Purpose'

Does the website include ALL the functional requirements set out at the Analysis stage. "YES" or "NO" and justify your answer
