Correct Answer:

Verified

Level 1 (initial). Software development follows few rules. The project may go from one crisis to the next. The success of the project depends on the skills of individual developers. They may need to finish the project in a heroic effort.
Level 2 (repeatable). Software development successes are repeatable. The organization may use some basic project management to track cost and schedule. The precise implementation differs from project to project within the organization.
Level 3 (defined). Software development across the organization uses the same rules and events for project management. Crucially, the organization follows the same process even under schedule pressures, ideally because management recognizes that it is the fastest way to finish.
Level 4 (managed). Using precise measurements, management can effectively control the software development effort. In particular, management can identify ways to adjust and adapt the process to particular projects without measurable losses of quality or deviations from specifications.
Level 5 (optimizing). Quantitative feedback from previous projects is used to improve project management, using the measurement skills shown in level 4.
