In "No Silver Bullets", what are some things that Brooks considers fake silver bullets? -
✔️✔️- High-level languages
- Time-sharing
- Unified programming environments
- Object-oriented programming
- ***Artificial intelligence*** (important to know, was on quiz 1)
- Expert systems
- Automatic/graphical programming
- Program verification
- Environments/tools
- Workstations
In "No Silver Bullets", what are some things that Brooks considers potential silver
bullets? - ✔️✔️Buy vs. build: don't reinvent the wheel when you can just buy it
What is software engineering? - ✔️✔️"Multi-person construction of multi-purpose
software." - Parnas
What are the 5 steps to constructing software? - ✔️✔️Requirements, Design,
Implementation, Verification, Maintenance.
What are the 3 types of perspectives on software engineering? Define the perspectives.
- ✔️✔️Business:
- Cost of Developing/Purchasing Software
- Time to market
- Profit
Engineering:
- Internal Quality of Software
Design:
- External Quality of Software
What are the essential ingredients of software engineering? - ✔️✔️People, Processes,
Tools.
What are the IN4MATX 43 principles of software engineering? - ✔️✔️Generality
Rigor/formality
Incrementality
Separation of concerns
, - Modularity
- Abstraction
- Divide and Conquer
Anticipation of change
Brooks believed that software engineering is hard because of the essential difficulties of
software.
What are the essential difficulties of software? - ✔️✔️Complexity
- Nonlinear increase with size
- Difficulty of communication among team members
- Difficulty of extending
Conformity
- Software must conform to human institutions and systems.
Changeability
- Software must be changed very easily because software is always subject to be
pressured to be changed
Invisibility
- Software is not tangible.
In "No Silver Bullets", what is the "werewolf" that Brooks tries to kill? - ✔️✔️The
"werewolf" that Brooks tries to kill is the missed deadlines, flawed products, and blown
budgets common to software projects
Requirements refinement/rapid prototyping: More accurate, specific directions make
mistakes less
common, and faster, more common prototypes allow clients to see what the result looks
like and allows changes/criticism
Incremental development: "grow, not build software." Ex: make the program functional
and make it yield basic results before fleshing it out and making it do more complex
things
Great designers: develop curricula, transfer technology that teach programmers
List 6 top reasons for software failure. - ✔️✔️Requirements Issues
- Lack of user input/involvement
- Incomplete requirements and specifications
- Changing requirements and specifications
Lack of Rigor/Formality (three losers)
