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.

Is Change Management a Myth or a Possibility

The theory that it is possible to manage organisational change (Change Management) in a particular direction has done the rounds for quite some time, but is it true about Change Management. Was Barrack Obama correct when he said, ?Change will not come if we wait for some other person or some other time. We are the ones we have been waiting for. We are the change that we seek.?
Or, was business coach Kelly A Morgan more on the button when she commented, ?Changes are inevitable and not always controllable. What can be controlled is how you manage, react to, and work through the change process.? Let us consult the evidence and see what statisticians say.

What the Melcrum Report Tells Us

Melcrum are ?internal communication specialists who work alongside leaders and teams around the globe to build skills and best practice in internal communication.? They published a report after researching over 1,000 companies that attempted change management and advised:

? More than 50% report improved customer satisfaction

? 33% report higher productivity

? 28% report improvements in employee advocacy

? 27% improved status as a great place to work

? 27% report increased profitability

? 25% report improved absenteeism

Sounds great until we flip the mirror around and consider what the majority apparently said:

? 50% had no improvement in customer service

? 67% did not report increased productivity

? 72% did not note improvements in employee advocacy

? 73% had no improved status among job seekers

? 73% did not report increased profitability

? 75% did not report any reduction of employee absenteeism

This shows it is still a great idea to hear what all parties have to say before reaching a conclusion. You may be interested to know the Melcrum report gave rise to the legend that 70% of organisation change initiatives fail. This finding has repeated numerous times. Let’s hear what the psychologists have to say next.

There is a certain amount of truth in the old adage that says, ?You can lead a horse to water but you cannot make him drink.? Which of us has not said, ?Another flavour of the week ? better keep heads down until it passes? during a spell in the corporate world. You cannot change an organisation, but you can change an individual.

At the height of the Nazi occupation of 1942, French philosopher-writer Antoine de Saint-Exup?ry said, ?A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral?. Psychology Today suggests five false assumptions change management rests upon, THAT ARE SIMPLY NOT TRUE.

1. The external world is orderly, stable, predictable and can be managed

2. Change managers are objective, and do not import their personal bias

3. The world is static and orderly and can be changed in linear steps

4. There is a neutral starting point where we can gather all participants

5. Change is worthy in itself, because all change is an improvement

Leo Tolstoy wrote, ?Everyone thinks of changing the world, but no one thinks of changing himself.? A prophet can work no miracles unless the people believe. From the foregoing, it is evident that change management of an organisation is a 70% impossibility, but encouraging an individual to grow is another matter.

A McKinsey Report titled Change Leader, Change Thyself fingers unbelieving managers as the most effective stumbling stones to change management. To change as individuals ? and perhaps collectively change as organisations ? we need to ?come to our own full richness?, and as shepherds lead our flock to their ?promised land?, whatever that may be. Conversely, herding our flock with a pack of sheepdogs extinguishes that most precious thing of all, human inspiration.
