Software Development Flashcards
What are the stages of the software development lifecycle?
Feasibility,
Requirements,
Analysis and design,
Implementation,
Testing,
Deployment,
Evaluation
What is the waterfall methodology?
A methodology that goes through each stage of the software development lifecycle linearly with clear detailed outputs at each stage.
What are the pros and cons of the waterfall methodology?
Pros:
- Easy to manage as each stage is well defined and seperate
- Gives a very clear timeline of events
Cons:
- Little client interaction
- Hard to go back to previous stages
What is the Rapid Application Development methodology?
A methodology that has several iterations with an increasingly functional prototype being made in each iteration, until the customer is happy for the latest prototype to be deployed.
What are the pros and cons of the RAD methodology?
Pros:
- Lots of client interaction
- Easy to go back to previous stages
- Developers can help guide clients into what is and isn’t feasible while not outright cancelling the project
Cons:
- Hard to guess how long the project will take
- Developers may lose motivation to keep working on the project without clear goals
What is the spiral framework?
A framework that is used with other methodologies that asks questions at each stage to manage risk and creates several prototypes over several iterations until the final build is made.
Pros and Cons of the spiral framework?
Pros:
- Risk Management
- Lots of Customer Involvement
- Flexibility with changing requirements
Cons:
- Complex and Expensive
- Difficult to manage
- Requires expertise in risk management
What is the agile methodology?
Development is broken up into several “sprints”, where in each “sprint” clear goals are made that can be completed within a couple weeks, this keeps programers engaged in the project as it never feels like the project is getting stuck.
Pros and Cons of the agile methodology?
Pros:
- Faster delivery due to smaller releases
- Customer Collaboration
- Flexibility to change
Cons:
- Scope creep can extend the project
- Documentation can be minimal
- Requires constant communication
What is the extreme programming methodology?
A methodology that puts developers at the focus, making sure the code that is written is well maintained and documented, typically used for programs that need to be correct 100% of the time. This is achieved via paired programming, shared ownership of the source code and good quality of code and documentation.
Pros and Cons of the extreme programming methodology?
Pros:
- Improved code quality
- Frequent releases
- Strong team collaboration
Cons:
- requires high commitment
- not suitable for very large teams
- heavy focus on code rather than other technical areas
What does each flow chart symbol mean?
Rounded rectangle - Start or end of program
Parallelogram - Input/Output
Rectangle - process
Rhombus - decision
Bordered rectangle - call of sub-process
