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.

Convert visits to sales to repeat purchases

The moment you start seeing more than a thousand unique visitors in just one day, we won’t be surprised if you’d be grinning ear to ear the entire week. But when weeks turn into months, you’ll then remember why you started off on this venture in the first place … and it wasn’t about just owning an immensely popular website.

People, like you, who’ve chosen to invest in eCommerce were most likely thinking along the lines of great ROI, revenues, and profits. Now that you have thousands of visitors, how would you like to have, say for a start, 1% of them buying the products on your site?

You know more about your own product prices; you do the math. But what might really interest you is that a slight change in that 1% conversion rate can already spell a big difference in your profits. Now imagine bringing that 1% up to at least 10%. That’s possible, but not if you simply rely on guesswork.

We rely on tests applicable to complex multi-variable systems, just like today’s typical eCommerce websites, in determining which combination of copy text, landing page images, form layouts, and background colours generate higher conversion rates.

Here’s how we’ll convert your visitors into buyers:

  • We’ll conduct A/B or even multivariate tests on your eCommerce website, thus eliminating guesswork in determining how to increase those conversion rates.
  • We’ll perform on-site and off-site web analytics to gain a deeper understanding of web usage to aid in our optimisation operations.
  • Through our expertise in copywriting, graphics and web designing, UI designing, and website QA, we can enhance and fine tune your site to give each visitor a uniquely engaging browsing experience.
  • We can also integrate CRM (Customer Relationship Management) systems so that you’ll have the technical advantage to turn one-time buyers into repeat customers.
How Armstrong World Industries is going Cradle-to-Cradle

The Cradle-to-Cradle concept holds that human effort must be biometric, in other words enrich the environment within which it functions as opposed to breaking it down. This means manufacturing must be holistic in the sense that everything is reusable and nothing is destroyed. Armstrong World Industries was the first global mineral ceiling tile manufacturer to achieve Cradle-to-Cradle certification. We decided to take a closer look at how they achieved this.

Armstrong Worldwide Industries has five plants in the UK alone. These produce an annual turnover of ?2.7 billion. They have been making ceilings for more than 150 years. Fifteen years ago and way ahead of the curve it started recycling, and has maintained a policy of not charging contractors for waste ever since. Along the way, it developed a product that can be re-used indefinitely.

The Challenge

Going green must also be commercially sustainable. In Armstrong?s case, it faced a rise in landfill tax from ?8 per tonne per year to ?80 per tonne per year. This turned the financial cost of waste from a nuisance to a threat. It calculated that recycling one tonne of ceiling materials would:

  • Eliminate 456kg of CO2 equivalents by saving 1,390 kWh of electricity
  • Preserve 11 tons of virgin material and save 1,892 gallons of potable water

They hoped to extend their own recycling project by asking demolition and strip-out contractors to join it, so they could reprocess their scrap as new batches of tiles too.

The Achievement

As things stand today, an Armstrong ceiling tile now contains an average of 82% recycled content. Indeed, if they could find more ceilings to recycle this could reach 100%. In the past two years alone, Armstrong Worldwide Industries UK has saved 130,399m? of greenfield from landfill, being the equivalent of 520 skips that would otherwise have cost contractors over ?88,000 to dispose of.

The Broader Context

Armstrong Worldwide Industries is a global leader in water management, and is bent on minimising its reliance on fossil for energy. It has implemented online measurement systems that feed data to its corporate environmental, health and safety system. This empowers it to produce reports, track corrective actions and measure progress towards its overall goal of being carbon neutral.

Next time you sit beneath an Armstrong Worldwide Industries panelled ceiling, spare a thought for how much ecoVaro consumption analytics could contribute to your bottom line (and how it would feel to be lighter on carbon too).

Fine-tuning your Operations and keeping our staff Happy with FieldElite

They are the engine that drives your operations, but are you really giving you value for your money? How much time is spent by your personnel on lengthy paperwork and record-keeping, as opposed to actually providing the service to your customers? Manual tasks create bottlenecks and slow your operations, which in turn affects service delivery and customer satisfaction. You want to reach more clients and boost your brand image, growing your market share and generating more revenue. Field Service Management (FSM) software comes in optimise the operations of your mobile workforce, cut down resource wastage, and enhance your productivity as a firm, by actually enabling your field staff to get more done, thus achieving their individual goals. In fact, according to a report published by Fortune Business Insights?, the global FSM market- which stood at $2.29 billion as recently as 2018, will have expanded to $7.27 billion by 2026. What does this mean for your employees, and how do they benefit from FieldElite?

  • Skipping the paperwork with end-to-end automation

Filing reports, keeping track of equipment used, working on the Excel sheets for multiple jobs on a daily basis, all through to the routing and billing- it can be a logistical nightmare. It’s not just about the hours spent poring through documents and typing away at calculators. Manual work exposes you to the risks of human error. Missing records, inaccurate assessments of the situation on the ground due to the overwhelming data streaming in, putting the head office staff under strain- it all hampers the productivity of the company. 

Take scheduling for instance. You have different employees, and various jobs that need their attention, at different locations. It can be a plumbing company whose clients have water filters that need to be repaired, gas boilers inspected, leaking pipes fixed, and others who need new installations to be set up. Assigning your personnel to the different situations will need to take into account the type of job, and the amount of time that it will require, aspects such as the location and the crew that is closest to it. At the head office you will want to keep tabs on the jobs that are in progress, pending, complete, those on hold, and even those that have been cancelled. Running all these through traditional manual processes is enough to drive you to the edge. What’s more, tasks that slip through your fingers amidst the confusion will result in negative feedback from your customers- which you don’t want hitting your brand.

With a field service job management software like FieldELite, you get to handle it all from one dashboard. Optimise your service delivery using the accurate scheduler, that allows you to account for the location of your employees, the status of the job- from the urgent ones like emergency tasks, to the normal duties such as routine maintenance, and low-priority tasks. The field service scheduling software comes with a real-time location feature that allows you to determine the employees closest to the client’s premises who will be appropriate for the job, map out the service areas and give you a birds-eye view of all the operations on the ground, while being updated with the progress of each specific task. Less time is spent travelling to- and from the central office, and more on actually tending to your client’s needs. You can even have situations where you can assign end-of-day tasks to employees who will be passing on that route on their way home.

  • Enhanced resource utilisation that promotes personal and professional development

Skill is key across the industries- from electrical services, solar panel installation, landscaping, home remodelling, pest control, plumbing, HVAC system maintenance, to construction and property management. For the job to be done appropriately and make your clients happy, you want to assign the task to an employee who is particularly proficient at it. This tends to be glimpsed over during manual scheduling since the personnel at the head office will be swamped with so many files, and will pick the first one that comes close to fitting the job description, leading to overlapping of roles. Sure, they may get it done, having seen their colleagues do it and even helping them out when they worked together before on similar projects- but will it be up to the required standard? On the other hand, the FSM allows you to ensure that you get the right technician for the task- who will be more motivated, boosting their performance.

What about accidents? Your employees want to feel safe as they go about their mandate. Many of the field service jobs are hazardous- such as electrical repair jobs, window cleaning tasks at high rise buildings, to elevator repair jobs where a slight glitch can lead to severe ramifications. Field service management software also comes in handy here, where the head office can be notified of any emergency the moment it occurs, and arrange for the necessary action to be taken immediately. That way, your employees will not feel neglected while they are out in the field, showing them that their safety is a priority to your business- which in turn increases their morale. 

  • Readily available knowledgebase and feedback system

When the employees have been assigned a specific job, they will require certain information about it. This includes the scope of the task, history of previous repairs or maintenance that was carried out, accompanying images if needed, risk assessment, any hazards or contaminants that they will need to prepare for, to notes left by technicians who had handled it. Having to keep checking their email, or picking up documents at the office for the day’s job and walking around with them all day as they tend to one customer after another, will slow things down, and not to mention frustrate them. However, the FSM system is directly accessible by the employees via app on their phones. The information needed for each specific task will thus be at their fingertips, speeding up the process and ensuring that they will be ready for each project being handled. 

While carrying out the job itself, the employees will use the very same app to update the system on how it is progressing, chat with the staff at the head office, update the inventory and even place orders for extra parts if necessary. Since mobile service management software apps like FieldElite also work in offline mode, the photos, reports and other entries that are made are collected by the app and saved on the device. Once a network connection is established, they are then updated to the central database- thus ensuring that the job can proceed regardless of the location. 

Once the job is completed, the customer input is also taken, registered in the system through their e-signature. A signoff comment included gives the customer the opportunity to indicate their experience with the job, and the feedback that they would like to provide. In case the job has not been completed, then the scheduling software kicks in, putting it in queue for another appointment to take care of the task, or resolve the issue that had caused it not to be completed the first time. The completed tasks head right to invoicing, which is also handled within the field service management platform, making it a seamless task for the head office staff.
