Object Oriented Analysis (OOA) in the Real World

Focus

SoftwareEngineering Problems

Will not Cover

Specifics of Shlaer-Mellor OOA

Applying OOA (gaining management support)

Practice vs. Theory

Elements that cause the difference

Requirements

Schedules

Size Complexity

Engineering Skills

"Silver Bullet Syndrome"

Requirements

Poorly understood systems yield poorly designed systems

not always known

evolve

Needs in sets of requirements

Quantify tradeoffs between different sets

Assess ability to meet multiple sets

Schedules

Knowing what you don't know

certain amount of prototyping to discover relevant issues

Needs for Schedules

Clairvoyance / Magic 8 ball

relevant feedback for adjusting and calibrating schedules

Size Complexity

Large size/complexity is not relevant

True size of the project is

Needs for Complexity

Ability to scale project up/down

Engineering Skills

Needs in Engineering Skills

identify good analysts

productive work for others on the team

"Silver Bullet Syndrome"

Overzealous & unrealistic

Object Oriented "can solve anything"

Needs in addressing "Silver Bullet Syndrome"

Frank and honest admittance of benefits and drawbacks for the project in question

Summary
