Final answer:
In Agile project management, happiness is not typically considered a measure of success. Quality, meeting agreements, and predictability are more traditional measures, with quality evaluation involving peer reviews, automated tests, and user feedback.
Step-by-step explanation:
All of these are commonly recognized measures of success in Agile project management, with the exception of happiness. While team morale and happiness can contribute to a project's overall health and productivity, they are not typically considered direct measures of a project's success in Agile methodologies. To evaluate the quality of a product in Agile, engineers may focus on attributes of the product such as functionality, durability, and usability. However, it is important to note that if prototypes were not tested adequately, this could lead to a false assessment of quality.
In Agile, meeting agreements, in terms of delivering agreed-upon features within a sprint or release, is a key measure of success. Moreover, predictability in Agile is associated with the team's ability to consistently meet commitments, which can be gauged over multiple cycles of development.
To evaluate the quality of a design, various methods can be used, such as peer reviews, automated tests, and user feedback on prototypes. Adequate testing is a critical part of this process to ensure that any design meets the necessary standards and requirements before being considered successful.
