of inventory. Shippers must deliver the goods on time. The distribution center must acceptable human error rate accurately forecast customer needs and properly manage inventory and orders. Order fulfillment errors hit the top and bottom lines. Product acceptable error rate for data entry that is not shipped diminishes the top line because customers cannot be billed. The bottom line is impacted through additional transportation, storage, and handling costs. There is also the potential for lost revenue http://panko.shidler.hawaii.edu/HumanErr/Basic.htm if customers decide to take their business elsewhere. Given the serious consequences, companies must decide how many fulfillment errors are acceptable. Is a 99.0% order accuracy rate acceptable? An error rate of 1% may seem small, but consider the cumulative effect over a year’s time. If ABC Company ships 1,000 orders per day, assuming a 5 day work week, 260 work days per year, the http://qcsoftware.com/wp/?p=118 yearly output is 260,000 orders with 2600 defects. If the average cost to correct an order is $200, ABC Company shipping 1,000 orders each day spends $520,000 for the year to correct mistakes. If they ship 5,000 orders per day, mistakes cost $2,600,000 per year. Shipping 20,000 orders each day cost over $10 million! A 1% error rate is too expensive and unsustainable for many distributors. Using Six Sigma’s Lean and Agile principles, raising the accuracy rate to 99.5% reduces the errors by half. While this is an improvement, companies are still wasting a considerable amount of money. By applying Lean and Agile principles, many companies have succeeded in achieving accuracy rates of 99.8% or better. It is impossible to completely eliminate errors. However, with proper planning and management, the distribution center can continue to contribute to the growth and profitability of a company.

Writers'Guidelines October 8, 2012 The Value of Error Reports By Mike Bassett For The Record Vol. 24 No. 18 P. 10 An exploration of coding accuracy can yield worthwhile riches for organizations seeking to maintain a strong financial foothold. Every healthcare organization is http://www.fortherecordmag.com/archives/100812p10.shtml expected to have in place an effective coding compliance program—one that will be http://sixsigmatraining.com/leading-six-sigma/what-is-an-acceptable-error-rate-in-contact-centers.html continually evaluated and reevaluated. To accurately assess the program’s effectiveness, it’s necessary to measure several outcome indicators, including error rates, which many HIM experts consider to be the most significant. There are various methods of determining chart error rates but, according to Rose Dunn, MBA, RHIA, CPA, FACHE, chief operating officer for error rate healthcare consulting firm First Class Solutions, Inc, the two most common are the “code-over-code” and “record-over-record” methods. In each approach, several charts are selected for review. The code-over-code approach divides the total number of correct codes by the total possible number of correct codes, while the record-over-record approach divides the number of records correctly coded by the total records in the sample. According to the AHIMA acceptable error rate publication Benchmarking to Improve Coding Accuracy and Productivity, the more widely recognized record-over-record method provides the advantage of being less labor intensive. On the other hand, it is considered to be more subjective because it may not include a definition of what counts as an error. In addition, some organizations may adjust the error rate based on the perceived impact of the errors. The more specific code-over-code approach is deemed more objective because errors are more clearly defined. According to the AHIMA publication, it is also more effective in identifying trends for educational purposes or process improvement. The disadvantages of code over code are that it takes longer, represents a change in thinking, and requires more of a learning curve for auditors. “Organizations prefer [record over record] for its simplicity,” Dunn says. “However, a gauge of coding accuracy is probably better reflected with the [code-over-code approach].” Lori-Lynne Webb, CPC, COBGC, CCS-P, CCP, CHDA, a coder III at Saint Alphonsus Regional Medical Center in Boise, Idaho, recalls that when she performed staff audits for one particular healthcare provider, she would randomly pull 25 charts per coder twice per year. She used a 100-point scale and would si

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 cal
