WHAT DO I MEAN BY COMPLEX? THIS SCREEN IS COMPRISED OF 10MODULES. THESE MODULES HAVE THE FOLLOWING NUMBER OF CONDITIONS, RESPECTIVELY: 4, 26, 10, 6, 3, 5, 3, 7, 3, 3. Over 17 Million possible layouts to this screen!

TOPICS •  WHAT IS OOD •  IS IT FOR YOU? •  MORPHOLOGY OF FLOWS •  MORPHOLOGY OF MODULES •  BENEFITS OF OOD •  QUESTIONS

OBJECT-ORIENTED? 

Conceptually, This is How it is Object-Oriented

WHEN TO USE OOD •  USE IT AFTER CONCEPTS ARE COMPLETE –  IN A RUP WORLD, SPEC OUT ALL SCREENS –  IN AN AGILE WORLD, SPEC OUT MODULES BY ITERATION

Confusion

Distant team members?

Requirements a mouth of numbers?

MODULE STATES

A DIFFERENT MODULE •  DESIGN FOR THESE HYPOTHETICAL BUSINESS RULES –  LOGGED IN USERS SEE ALL POSSIBLE CONTENT –  NOT LOGGED IN, BUT CAN BE IDENTIFIED VIA COOKIE –  UNKNOWN USER

CLUMSY WAY TO DO THIS

USING NESTED MODULE

USING SUB-MODULES

REFERENCED MODULES

ERRORS

NUMBERING CONVENTIONS WITHIN OOD HOME100.10 STATE 20 STATE ID MODULE ID UNIQUE NUMBER WITHIN THIS SECTION. ALONG WITH THE SECTION NAME, THIS DEFINES THE SCREENID SECTION NAME

BENEFITS OF OOD •  HELPS BRIDGE MANY DIFFICULTIES PROJECT TEAMS FACE •  IT CAN BE USED TO EASILY DESCRIBE COMPLEX BUSINESS REQUIREMENTS OR RICH INTERACTIONS. •  YOU CAN FULLY DESCRIBE AND DESIGN ALL STATES A SCREEN CAN BECOME. •  COMPLEXITY IS REDUCED THROUGH DECOMPOSITION •  UNIVERSAL REFERENCES AND IDS ARE CREATED THAT CAN BE USED BY ALL TEAMS IN THE PROJECT
