If your downtime is related to replenishment of supplies, such as film for an over wrapper,
then additional buffering through accumulation will increase your line efficiencies.
For example, if you had $ 500 in your checking account and $ 3000 in your savings account and you were convinced that consolidating these two accounts would make your life easier,
then you could simply combine the accounts and carry the $ 500 in your checking account balance knowing that you still had an
additional $ 3000
buffer in the account as well.
