Simple design
Collective ownership
Continuous integration
Sustainable pace
Description
Enough design is carried out to meet the current requirements and no more
Developer pairs work on all areas of the system so no islands of expertise develop — anyone can change anything
As soon as work on a task is complete it is integrated into the whole system; all unit tests must then pass
Large amounts of overtime are not acceptable as the net effect is often to reduce code quality and medium-term productivity
Correct Answer
(1) Simple design,Enough design is carried out to meet the current requirements and no more
(2) Collective ownership,Developer pairs work on all areas of the system so no islands of expertise develop — anyone can change anything
(3) Continuous integration,As soon as work on a task is complete it is integrated into the whole system; all unit tests must then pass
(4) Sustainable pace,Large amounts of overtime are not acceptable as the net effect is often to reduce code quality and medium-term productivity
Explanation
Simple design: just enough design for current requirements. Collective ownership: all developers take responsibility for all code — anyone can change anything. Continuous integration: completed tasks integrated immediately, all unit tests must pass. Sustainable pace: overtime reduces code quality and productivity.
