Oscillation and feedback
Output changes over time, creating room for error in the measurement process. Because there is necessarily a delay between measuring data, analyzing the data and identifying a problem, and ultimately implementing a solution, solutions may be implemented after the problem is no longer relevant (as shown in the graph—output is already improving before the solution for the prior dip in output is implemented). Timely discovery and reporting of measurements helps minimize this problem of delay in information flow.
