Designers on a software project must have a well thought out and well-executed design; therefore, many choose a structured methodology to approach their system development life cycle (SDLC) or object-oriented approach. Designers may decide to take an object-oriented (OO) approach to systems/software development, which is more iterative in nature and incremental. Compare and contrast the structured design approach with the OO approach to systems/software development.
As an alternative discussion topic, design patterns, which are not complete designs that can drive code, provide the base for how to solve complex project and system issues. Describe some of the following patterns below and how they deal with the creation of objects, identification of common communications patterns between objects, provide identified relationships between entities, or patterns of organizational decision making.

Creational design patterns
Structural design patterns
Behavioral design patterns
E-business design patterns
