The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

The Cloud: Changing the Game for Small Businesses

There is a consensus among cloud experts that the onset of cloud computing will benefit small organisations the most. In fact, many even go as far as saying that the cloud and small businesses are a match made in IT heaven. How much of this is true and how much of this is merely part and parcel of the hype surrounding cloud computing?

The Cloud as the Great?Equaliser

If you closely examine the essential characteristics of cloud computing, particularly public cloud services, you will see why small organisations would be very interested in the cloud, and would eventually flock to it, like moths to a flame. And why not? Cloud computing is turning out to be the weapon that can allow small and medium organisations to compete on a more level playing field against large enterprises.

Here are some cloud computing benefits that may just close the gap between the two.

  • Significantly lower IT spending. With little to no investment at all on hardware infrastructure and practically zero maintenance costs, SMBs that would have required substantial capital for IT are now finding it easy to get a business started from scratch or develop and test out new products by using the cloud as the backbone of their IT set-up. The pay-as-you-go pricing scheme that cloud computing offers allows companies to start small and scale up as needed, or when the revenue starts coming in.
  • Higher employee productivity. Licensing fees for software applications can run high even if you don’t have a large staff. Good thing there are now a host of cloud-based office tools – word processors, spreadsheets, presentations, accounting systems, etc. – that can boost employee productivity without the corresponding costs that small businesses can ill afford. Plus, team members in remote locations can continue to collaborate with the rest through any internet-connected device in real time.
  • Easier, better communication. The easy accessibility of communication apps has also changed the way employees interact with fellow employees and more importantly, with customers. Whether through email, instant messaging, or social networks, cloud services have given individuals and businesses more ways of giving and getting feedback. The best thing about it is that most of these services don’t cost much or are even free, giving SMBs ample tools to create better products and improve service.
  • A Look at the Figures Many small businesses are already seeing the potential in the cloud, with SaaS (Software as a Service) applications most commonly used among the early adopters. These services include email and other communication apps, file sharing, and backup.

In a February 2012 Edge Strategies survey (commissioned by Microsoft) of 3,000 small businesses in the US, the following data came to light:

  • The number of small companies with 2 to 10 employees using paid cloud services will triple in the next three years;
  • Current cloud users report purchasing an average of 4 services in the cloud now and expect to use 6 in the future;
  • Fifty percent agree that cloud computing is going to become more important for businesses such as theirs.

Further, a survey of 323 SMBs recently released by social business site Spiceworks and sponsored by EMC reveals that from 48 percent at the start of 2012 and 28 percent a year ago, 62 percent of the businesses surveyed now use some type of cloud app.

What these numbers show is that cloud adoption among small and medium enterprises is starting to gain ground and for sure, more will do the same as understanding and awareness increase. Yes, these businesses should still perform their due diligence as there is no one-size-fits-all cloud solution. But for those companies who have managed to find the right cloud apps and services for their needs, it’s all sunny skies up ahead.

What Heijunka is & How it Smooths Call Centre Production

The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.

Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.

Smoothing Production in the Call Centre Industry

Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.

Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.

This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.

A Modern, More Flexible Approach

Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.

Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.

A Worked Factory Example

The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.

Predictability, Flexibility, and Stability at Call Centre Service

The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.
