We study a dynamic team problem in which two players contribute to a common project that
leads to a success with some probability increasing with effort. Players are informed of
the success or the failure of their partner with a time lag. We interpret this delay as
a technological constraint on information transmission. We find that
the equilibrium payoff follows a regular cyclical pattern and the strategies are bang
bang. This contrasts with the case without delay in which payoffs and efforts are constant over time. Also, there exists an asymmetric equilibrium if and only if the time lag  is sufficiently small.
