Step-by-step explanation:
Teams can fail due to various factors, such as lack of communication, poor management, and a negative work culture. In Hiroko's team, the frustration and lack of motivation to come up with innovative ideas may be attributed to several reasons.
First, the team did not receive clear feedback on why most of their concepts were not implemented, which can lead to a sense of uncertainty and demotivation.
Second, if the team members perceive a lack of support from management or a culture that discourages new ideas, they may become disengaged and stop putting effort into generating innovative solutions.
Lastly, if there is a lack of incentives or opportunities for advancement, team members may lose their motivation to contribute.
