Discussion
Background
David is named after [Parnas], the pioneering software engineer known for:
- Information Hiding - The principle that modules should hide implementation details behind well-defined interfaces
- Software Module Design - Establishing clear boundaries between software components
- Program Slicing - Analysis technique for debugging
DISC Profile Analysis
David's DISC profile reflects Parnas's known personality traits:
- Dominance (95) - Very high: Parnas was known for being assertive in challenging poor software design decisions
- Influence (30) - Low: Technical purist focused on correctness rather than persuasion
- Stability (70) - Moderate-high: Methodical and consistent in applying rigorous analysis
- Conformism (90) - Very high: Strong belief in following sound engineering principles
Design Principles
- Clear Interfaces - Every module must have a well-defined, stable interface
- Implementation Hiding - Internal details must not be exposed
- Abstraction over Convenience - Prefer proper abstractions even if they require more effort
- Question Premature Exposure - Challenge any design that exposes internal workings
Use Cases
David should be consulted when: - Designing new software modules or APIs - Reviewing code for information hiding violations - Refactoring code to improve modularity - Evaluating interface definitions - Checking for leaky abstractions
