Chapter 2

QuestionAnswer
Workflows Requirements workflow Analysis Workflow Design workflow Implementation Workflow Test Workflow
Which workflow predominates at the beginning of the life cycle? Requirements workflow
Which workflow predominates at the end of the life cycle? Implementation and test workflow
Which activities are performed throughout the life cycle? Planning and documentation
List the 7 life cycle models Code-and-fix model Waterfall model Rapid prototyping model Open-source model Agile processes Synchronize-and-stabilise model Spiral model
Disadvantages of Code-and-fix model No requirements No specifications No design
Advantages of Waterfall model Enforced discipline of documentation Maintenance is easier
Disadvantages of Waterfall model Stringent document rules can be a weakness
Advantages of Rapid prototyping model Essentially a linear process since the feedback loops, although present, are unlikely to be needed
Disadvantages of Open Source model Closed-source software is maintained and tested by employees Open-source software is generally maintained by unpaid volunteers. Consequently, in an open-source project, there are generally no specifications and no design.
Acronyms of Extreme Programming: YAGNI, DTSTTCPW You aren't gonna need it do the simplest thing that could possibly work
Advantages of Spiral Model It is easy to judge how much to test No distinction is made between development and maintenance
Disadvantages of Spiral model For large-scale software only For internal (in-house) software only
BEST SUGGESTION MODEL "Mix-and-match" lifecycle model

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
