5 Agile Development and System Modelling

Question 1

What product development system did we use?

Answer 1

We used an agile inspired apporch. The project did not go on long enurgh for us to have several iterations, but you could look at what we did as one iteration. We ended up with (partial) prototypes, that could be showcased to the client, where they could have come with feedback and changes.

Question 2

What is waterfall lifecycle?

Answer 2

A type of lifecycle of complex system developments:
Plan, Analysis, Design, Implementation, Test, Deploy

Question 3

What is iterative lifecycle?

Answer 3

A type of lifecycle of complex system developments:
Plan, Analysis, Design, Implementation, Test, Deploy
per iteration/sprint

Popular method, with product owner, scrum master and team.

Answer 27

Hard prototypes are physical objects, like making a first draft of a new drone.
Soft prototypes are prototypes of intangible concepts, like testing a website layout by drawing it on some paper

A functional prototype that include features familiar to users together with novel features a designer chooses to incorporate after careful analysis of relevant data.

Bring users into development process early

Meaning: Already have some ideas about how it should work, and make a combination of the old and new you have never tried to see which ones work best tigether
