Answer:
Negative synergy.
Step-by-step explanation:
Synergy is defined as the process by which different individuals and groups come together and pool their resources to achieve a common goal. The effect of their combined effort is more than the sum of each individual acting alone.
However when there is negative synergy, the combined effort is less that sum of individual efforts, that is the individuals acting alone can achieve more than working together.
Members are dropping off the Alpha team because of lack of interest and the team has not achieved any of its set goals. This is a negative synergy because the individuals working alone and interested in the project, would have made more progress than Alpha team.
