Problem $10-22$

An office manager is concerned with declining productivity. Despite the fact that she regularly monitors her clerical staff four times each day$-$at $9$:$00$ AM$,11$:$00$ AM$,1$:$00$ PM$,$ and again at $3$:$00$ PM$-$office productivity has declined $30$ percent since she assumed the helm one year ago.

What would you recommend that the office manager do to improve office productivity in the future?

Monitor at four hour intervals instead of two$-$hour intervals.

Invest more time monitoring.

Randomize the timing and amount of monitoring.
