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.

Mobile Security

Today’s advanced enterprises make extensive use of mobile devices in order for team members to exchange information, collaborate, and carry out business whenever and wherever they need to. BlackBerries, iPhones, Google Phones, and other smartphones as well as PocketPCs and PDAs are now allowed wireless remote access to the enterprise network.

As a result, they introduce additional vulnerabilities into the system.

  • Bluetooth exploits and unencrypted passwords can allow malicious individuals to gain access to private information.
  • Various wireless technologies that have substantially simplified the task of transferring data have provided openings for malicious code. In addition, the diversity of these wireless technologies combined with the constrained environments of these devices have made it difficult to come up with an all-in-one solution.
  • All PocketPCs, PDAs and smartphones can be synchronised with PCs and laptops, giving malware an entry point into computers and networks. Memory cards are guilty of this too.
  • VoIP, which are usually unencrypted, allow other people to perform unauthorised capture and recording of private conversations.

Mobile security is still an emerging discipline. Because of this, many organisations that allow members’ mobile phone access into the network don’t actually have a specific security policy for such devices.

That’s why we’re here to help. We’ll conduct a thorough evaluation of your security policies and systems in relation to mobile devices and seal gaps we spot along the way. If you don’t have the needed policies or if what you have needs an overhaul, we’ll set everything up (including the needed applications and infrastructure) for you.

Once we’ve got everything in place, you won’t have to worry about the vulnerabilities mentioned earlier. In addition to that, your organisation will already be capable of preventing the following:

  • Access to company information when the phone ends up in the hands of anyone other than the authorised user.
  • Being billed for phone usage due to virus activity
  • Unauthorised phone activity monitoring through spyware
  • Other disruptions caused by mobile-based malware

Other defences we’re capable of putting up include:

Implementing Large-Scale Complex Business Change

Sometimes, driving your people to work harder is not enough for your organisation to withstand the pressures laying siege to it. With uncertain economic conditions, unpredictable fresh competition, and looming threats from the environment or even pandemic-grade diseases, empowering your people to not only ‘think’ but also to ‘step’ out of the box is currently the name of the game.

However, such initiatives typically require sweeping changes throughout your entire organisation … and to think even the slightest change is often met with hard resistance.

Whether you’re about to undergo an M&A, relocate due to a major catastrophe, scale down to a skeletal workforce, or implement a brand-new company-wide strategy, our systematic approach to large-scale complex business change can help you make the transition as seamless as possible.

We understand the importance of the human aspect in change management. That is why we’ll focus on making your people appreciate the benefits of having to learn new skills, perform new tasks, employ modern technologies, and go through new processes in order to tone down the resistance level.

Our entire process spans from top to bottom, wherein we’ll start with your sponsors, down to your managers, and then to other stakeholders in making them appreciative of the needed changes and in order to achieve alignment with your organisation’s goals. Our top to bottom approach is also aimed at casting a positive “shadow of the leader” on people down the line, enabling them with an optimistic view despite the gruelling tasks before them.

We invite you to have a look at the steps we take in implementing large-scale complex business change to win over a strong and lasting commitment to it.

Evaluating the Required Change

Large-scale complex business change initiatives can be implemented expeditiously and economically if you’ve clearly defined the scope of the change as well as the forces that shape your organisation. You’ll want to know which areas yield easily and which are hard to change to determine where and how you’re going to focus more of your efforts on.

To arrive at a sound and systematic plan, we first gather as much information as needed and analyse them. We determine whether your departments have the required capabilities and how we can arrive at a clear organisational alignment. That way, we don’t waste time, effort and resources when the moment comes to carry out the plan.

These are some of the diagnostic procedures we perform in evaluating the required change.

  • Change complexity analysis. We’ll assess the contribution of people and task factors to the overall complexity of the change project. This will help us determine how to approach the problem efficiently.
  • Causal analysis. By establishing cause and effect relationships, we can identify root or circular causes. This will allow us to pinpoint problem areas and prevent a repetition of past mistakes.
  • Structural analysis. Any company is propped up by a number of structures: organisational, process, motivational, social, and physical, among others. Understanding the structures that drive, motivate, hamper, connect, and influence your people’s behaviours can provide insights as to how or where structural change can best be executed.
  • Context analysis. We’ll look into market forces as well as political, economic, social, technological, legal, and environmental factors enveloping your business. We’ll also analyse your driving objectives, organisational alignment, and organizational capabilities. By analysing the internal and external environment in which your business currently operates, we can formulate a customised strategic and effective plan of action.

Managing Stakeholders

Change initiatives won’t prosper without total commitment from all stakeholders. Stakeholders refer to people in your organisation who either have interests in the change project or can be affected by it.

We deal with your stakeholders starting from the top because if we can’t gain full commitment from those already in the best position to spur the diverse entities in your company into active cooperation, striving to secure commitment from other areas will be futile.

That is, if you don’t have the full support of your key and principal sponsors, i.e. the people who have the biggest say and have greatest control over resources in your organisation, you can’t hope to sustain the change endeavour, let alone provide the much needed spark to get it started.

Here’s how we carry out our stakeholder management actions.

  • Conduct research to identify all stakeholders: the sponsors, your internal and external partners, the main targets of the change, and all interested parties. That way you can “switch on” implementors of each change action in the proper sequence.
  • Not everyone will offer resistance to your change endeavours. We’ll help you identify those stakeholders and sponsors who are willing to offer support, evaluate the level of support they are willing to give, harness all available supports and utilise them extensively to benefit the change.
  • Gain a deeper understanding as to why certain stakeholders are willing to lend support. In doing so, we can implement the right strategies that will encourage them to continue supporting you.
  • Assemble a leadership team that will champion your change initiatives. We’ll facilitate effective collaboration among its team members, transforming them into a cohesive force designed to carry out plans and motivate everyone else down the line.
  • Upon realisation of the change project, we’ll see to it that all stakeholders get a taste of the carrot at the end of the stick. This will encourage them to continue active cooperation in future change initiatives.

Planning for the Change

Anyone who has experienced having their car stuck in the mud knows that stepping on the accelerator will only get the vehicle trapped even deeper. Without the aid of a towing truck, getting the car out will require careful planning since different combinations of pulling, pushing, lifting, rocking to-and-fro, and stepping on the accelerator may be needed.

Of course, some combinations are just better than others. The same principle holds when effecting change.

Our approach to change management typically varies depending upon the information we obtain from the different analyses performed earlier. For instance, since not all organisations are suitable for a collaborative approach, we will employ either collaborative, consultative, directive, or coercive change management strategies wherever applicable.

A well-planned change will result in a smoother, less costly, and less disruptive transition. Here’s how we’ll help you plan your change initiatives.

  • When put in a predicament similar to the car-in-the-mud, the basic strategy entails identifying the current resisting forces and predicting what other resisting forces may be encountered along the way. After researching and pointing out your organisation’s resistance forces, we’ll lay out the most appropriate facilitation, education, and negotiation techniques.
  • To bring down wastage to the lowest possible levels, we’ll engineer a change delivery plan that involves the most cost-effective sequence of driver, process, technology, organisational, and people alignment.
  • To win and maintain a high level of trust, confidence and commitment from all sponsors and stakeholders, we’ll present a clear road map of the change process as well as landmarks that will prove how far we will have gone. These landmarks will then be brought to each sponsor’s and stakeholder’s attention each time they are arrived at in order to build up assurance and continued commitment.
  • We’ll design measurement tools and schedule reporting deadlines so that you’ll know what to look forward to and when to expect them.

Managing the Change

Your company will hold a better chance of maintaining a sizeable lead over the rest of the pack if you constantly establish a rally point and instil in your stakeholders the drive to rally to that point from the get-go. To make this happen, your company must undertake the unfreezing, transition, and refreezing phases of change skilfully in order to bring all stakeholders into the right mindset.

Our specialists’ systematic and efficient methods for each of these phases are designed to simplify the management of each phase as well as provide a seamless shift from one phase to the next. This is what we’ll do:

  • Set up a change project management office to ensure that everything associated with the change initiative is given the needed attention and resources even while all the other usual processes in your organisation run concurrently.
  • To unfreeze your people and get them started on the road of change, we’ll employ unfreezing techniques wherever they are most appropriate. We’ll resort to different kinds of methods ranging from presenting persuasive evidence justifying the need for change to showing a motivational vision for inspiring your people to embark on the change process.
  • Since it is during the transition phase when your people can find themselves groping in the dark, we’ll offer executive coaches for your senior managers; facilitators to provide guidance during team meetings and other change activities; coaches to educate and inspire them to meet the change with the right attitude; trainers to teach new systems, procedures, and technologies; as well as employ a variety of other techniques in order to make the transition phase as seamless as possible.
  • Although your people should always be ready to undertake the next major change after a previous one, there should be points in between where they can taste the spirit of success, establish a temporary base to rejuvenate, and immediately gain a deeper understanding of the nearby terrain so as to envision the next rally point. We’ll see to it that this vital phase of change is carried out completely.
