tolerance for cash shortages bearable or terrible? April 17, 2013 | by D. B. "Libby" LibhartIf you lost 5 percent or more of your sales and it just can't be explained how http://panko.shidler.hawaii.edu/HumanErr/Basic.htm it occurred, would it bearable or terrible to the financial health of your business?Shortages in cash may be somewhat understandable. Cashiers handle cash transactions, credit cards, gift cards, checks, traveler's checks, and any number of discounts and coupons. When transactions go awry for some reason, they must void, no sale, refund, discount, or reduce the price in some way. During interactions with the public http://www.fastcasual.com/blogs/your-tolerance-for-cash-shortages-bearable-or-terrible/ they may encounter attempts at credit or gift card fraud, bad checks, counterfeit, price changing, quick change schemes, drive-offs, walk-offs or some other new scam of the day. The cashier is expected to know all of these transactions, handle them flawlessly, and yet have a perfect cash drawer at the end of the shift.But what if they don't? What if the cash is short? And how much does the cash till have to be short to get your attention? Some owners and/or managers create a policy that shortages must be paid back. There are many reasons why this is not a sound policy, and against the law in some states. Frequent cash drawer overages are not desirable either. Overages may be indicative of poor cash management or worse, manipulation of the cash operation and theft.So, what amount of cash shortage, or overage, is acceptable within the framework of your business? Knowing that a perfectly balanced cash drawer is not practical in a blind remittance procedure, what is bearable? More importantly, are cash handling policies written, performance expectations clear and disciplinary actions for excessive cash overages and shortages fair

There are two diametrically opposed answers to the question posed in the title. Here is the first one: a jaw-dropping number of calls completely riddled with errors is totally acceptable in call centers today. Preposterous, you say. Please keep reading. First, the big picture. In contact centers no one talks about Six Sigma or Five-9s, or Taguchi's "on target with minimum variation." Those ideas are constantly being discussed in manufacturing, but are laughable notions in call centers. No one talks about it. No one aspires to it. No one even thinks anything remotely close is even possible. Further, no one does any benchmarking to see what "world class" companies do so that "stretch goals" can be established around even a "tolerable" level of agent errors. OK, fine you say, so contact centers don't set their sites very high. What if we just went from center to center and determined the error rate and called the average across those centers "acceptable?" You wouldn't even be able to do that. In manufacturing, specs are sine qua
