Line 24:
As illustrated in the following figure, many projects developing large and complex software-reliant systems decompose development into a small number of increments (Vs) having correspondingly shorter durations. The shift-left illustrated by the dashed red arrows occurs because parts of the single, large waterfall V model’s types of testing (shown in gray) are shifted left to become increments of the corresponding types of testing in the smaller incremental V models. When each increment is also a delivery to the customer and operations, then incremental shift-left testing shifts both developmental testing and operational testing to the left. Incremental shift-left testing is popular when developing large, complex systems, especially those incorporating significant amounts of hardware. Like traditional shift-left, the transition to incremental shift-left has also been largely completed.
