Think about any decision. You have to think about, not only the consequences of that decision immediately, but also the consequences in a month, three months or a year. An immediate positive consequence may create the circumstance for a negative consequence in three months time.
Same thing goes for a problem to be solved. You have to think about, not only the consequences of that solution in the near term, but the consequences in a month, three months or a year. An immediate solution may create the circumstances for a larger problem in three months time.
Take a high mileage vehicle and extend its preventive maintenance cycle by 30 days. You will save the cost of a maintenance cycle. In three months time, you will not likely notice any difference, but over two years time, you may experience catastrophic vehicle failure. And, it may not just be the cost of the repair, but the delay in the critical path of a project (just to save an oil change).
