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.

ESOS ? Why we must have it

The 9,000 big UK businesses directly affected by the new Energy Saving Opportunity Scheme could save UK?250 million between them, or an average UK?27,000 each, if they reduced electricity consumption by just 1%. The total amount is equal to the output of five power stations, at a time when Britain?s grid is under strain.
On 26 November 2014, UK Energy and Climate Change Secretary Ed Davey met with over 100 opinion makers from businesses, charities and universities at the Institute of Directors. The gist of what he presented was:

?Britain?s big firms are spending around ?2.8 billion extra each year on inefficient energy technologies ? the equivalent output of nearly five power stations;

Now is the time to seize the opportunity with ESOS ? and organisations up and down the country are already gearing up to make changes to save energy, save money and save the environment.

If business did what business is supposed to do [that is innovate to make money] and act and invest, it will save ? and that’s the bottom line.?

The environmental benefits are as important although EcoVaro agrees with Ed Davey for taking a pecuniary approach. Businesses above the threshold of 250 staff and a balance sheet of UK?34 million would have not achieved their status unless they spent their money wisely.
The discussion panel included Rhian Kelly (Director of Business Environment at CBI), and Paul Ekins (Director UCL Institute for Sustainable Resources & Deputy Director of the UK Energy Research Centre). Hugh Jones, Managing Director, Advisory at the Carbon Trust responded to Ed Davey?s remarks by commenting:

?At the Carbon Trust we have already engaged with hundreds of businesses on ESOS, helping to explain how they can achieve compliance while also making significant energy savings and cutting carbon.
Businesses often aren’t aware of opportunities in energy efficiency, or they don’t realise how attractive the paybacks can be. By requiring companies to understand exactly how they can make cost-effective investment in energy efficiency, they are far more likely to take action.
From the interest we have seen so far we expect ESOS to benefit British business by helping companies to reduce overheads and increase competitiveness.

The UK?s Energy Saving Opportunity Scheme ESOS is a gold mine of opportunities for big business, the environment and the population that breathes the air. Measurement of critical energy throughputs is the beginning of the process. EcoVaro is standing by to help you convert your data to meaningful information.

Importance of Field Service Management Software for Mobile Working

Technology has been evolving at a fast pace. Changes are also happening simultaneously within different industries. Making a great difference in the business world right now is the trend of mobile working.

Thanks to platforms and tools, working while on the go is now easier and more streamlined. The field service industry also benefits from these technological advances.

Mobile technicians can now give excellent performance and do their job efficiently with no hands-on management needed.

Keep in mind that field service management is no joke. So, to achieve a smooth business and mobile worker management, you’ll need to invest in good mobile service management software.

But First, what is Mobile Working?

Mobile working is a method of working that is not tied to a single physical location.

It isn’t just about checking your emails on your phone or ringing your colleagues via Bluetooth while driving your car to the next appointment. It’s so much more intricate than that.

Effective mobile working means you’re mobilising your workers. Field technicians should have everything they need to complete their day to day work. You’re giving them their entire office in the form of a mobile device.

Mobile working, via a handheld device, allows field technicians to do the following:
● Access and input information about a work order
● Collaborate on projects
● Stay in touch with colleagues, clients and management
● Utilize effectively the different software features

Your field workers should have the support of a dynamic management tool that ensures they are sent to the job that utilises their skills effectively and efficiently.

That’s where a good field service management software shows its importance.

The Role of a Field Service Management Software

Your mobile workforce is scattered across various physical locations. You’ll need to connect with them and simultaneously manage your field service business.

Thanks to the increasing connectivity and improvement of technologies for this purpose, mobile workers can easily input and access any work order details via your chosen field service management software.

What Makes a Good Field Service Management Software?

There are 3 main points to consider when investing in a good mobile workforce management software:

1. It’s simple and familiar to use. Like we mentioned before, be sure to mobilise your field technicians – not the back-office system. Make sure your chosen app or software has a simple user interface so your workers can be on-the-go easily.

2. It works offline. Rural areas and highways can have poor connectivity. Sometimes agents will need to work in areas that have little to no network coverage or are deep down working in tunnels or around heavy machines and turbines. You don’t want your field technicians unable to complete work due to connectivity issues. Make sure to choose software that can function on their device while offline.

3. It’s flexible (and maintainable). Your field service management of choice should have real-time visibility. Flexible and improved visibility for a field worker means that they can do their best in any task. They can share or get critical information about orders and customers. This drastically improves job completion rates and customer satisfaction.

Importance of Field Service Management Software to Mobile Working

Utilize the technology that is available to you. Your mobile workforce should have the right tools so they can make sure to do their fieldwork efficiently without worrying about tedious administrative work. Any back-office task can be done quickly through a field service management software.

And that’s the most important role of a great mobile service management app — effective mobile worker efficiency.

Benefits of a Field Service Management Software to Mobile Working

● Additional revenue: By simplifying the administrative work, your field technician can even double the work order in their daily shift, meaning more profit for the business.

● Cost-cutting: The cloud-based nature of a field service management software means that your business can reduce the cost of on-site IT.
Your mobile workforce can operate from wherever they have an online connection, meaning less reliance on offices and building costs.

● Boosts overall efficiency: A mobile workforce management software allows you as a manager to monitor in real-time where they are and what they are doing. It means that problems can be identified and dealt with immediately.
Your field technician, in turn, becomes more efficient because the technology allows them a quicker response, instead of taking too long finishing administrative tasks.

What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?
