At home we get our milk delivered every Saturday by a local farm. To make it last we freeze two of the three 4ltr bottles. In theory that means we have the current bottle, one fresh bottle To ensure we have enough milk we have to estimate the best time to take the milk out of the freezer and allow 24hrs to defrost. Get it wrong and we have to try to speed defrost the milk with the kettle. Although this works sometimes, it usually makes a mess and tastes weak. The urgency of poor planning leads to a poor outcome.
Finding the balance took a bit of effort but pays off. The same applies to our use of resources in the workplace.
