Ecommerce - 1.5 System development Flashcards
Waterfall
- working toward a once-in-a-long time release schedule.
- Waterfall was more benfitical in the days of software distribution on CD-ROM. You needed to completely finalize the software before shipping it as delivering bugs to customers was a very bad thing. Also, it needed to have plenty of upgrade for the user to feel it was worthwhile to purchase and upgrade.
Agile
- Agile is a complete software development cycle. Usually focuses on smaller increments.
- Agile is iterative.
- Agile fits better with other delivery means (automatic)
- because once can deploy often, it gives much faster feedback, and the product doesn’t have to be polished. Instead of one release a year, you can release weekly or even daily.
SCRUM
- Scrum is based around a sprint (a set period of time for work to get done). Commitments are made to ensure that the work is completed.
