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 Future is Smarter with a Smart Meter

Traditionally, electricity and water meter consumption was measured via analogue meters. Utility billing was based on actual consumption units obtained from the meter by meter readers. This entailed physical visits to the metering point. Lots of challenges came with meter reading; talk of customers feeling their privacy is intruded, meter readers encountering hostile customers, dogs, closed gates. The result was estimated bills that were most often than not very high.

Smart meters can be dubbed as the ?next generation? type of meters. Smart meters send wireless electronic meter readings to one?s energy supplier automatically. There are both gas smart meters and electricity smart meters. Smart meters come with in-home displays, which give someone real-time feedback on their energy usage and the associated cost.

Smart meters communicate meter readings directly to utility companies therefore no one has to come to your home to read your meter; and neither are you required to submit meter readings yourself. This not only reduces costs, but leads to more accurate electricity bills practically eliminating estimated bills. Smart meters signal the end of estimated bills, and the end of overpaying or underpaying for energy.

Whereas a smart meter in itself does not save you money, the add-ons (in-home displays) that come with the smart meters and which give someone real-time feedback on their energy usage helps them to reduce the unnecessary energy use and this ultimately leads to better oversight into how to lower utility bills hence better management of one?s energy use.

In summary, a smart meter is a technology that enables energy consumers to see their energy as they use it, a technology where energy is displayed as it is being used and wireless ratings sent. Adoption of smart meters would mean the end of estimated energy bills.

Smart meters are also promising a smart future where all energy consuming devices can be connected to the internet and centrally controlled using computers or smartphones. This means one is able to switch off lights and other energy consuming devices from a central point, hence make savings and this will enable them to have greater control of their energy use, hence more comfort, convenience and life will be cheaper for all. This is the smarter future we are all looking forward to.

Project Management

In a cutthroat market, where the competition is constantly on the attack to break into your market share, implementing a project-based system can give your organisation the necessary tools to be more efficient and agile.

However, rapidly changing consumer demands, technologies and other factors make it ever more difficult to generate a strategic advantage from projects, let alone develop one. Also since a large organisation can easily end up having to manage multiple projects at the same time, the new management paradigm can appear too complex.

What your company really needs is the expertise that can guide you starting from conception and planning, down through procurement and execution in order to maximise whatever resources you have. Each move must be well thought out so that there are clear goals and objectives as well as methods to achieve them.

Programme Management

Are you running multiple projects pointing to an overall strategic direction? Then you’ll need more than just a “scaled-up” version of project management to make sure every component’s work effort is well coordinated to achieve your enterprise’s desired outcomes.

Through our expertise in programme management, we’ll work with your stakeholders, executives and clients to achieve the following:

  • Design a well-articulated management structure and clearly define decision-making roles & responsibilities – This will ensure decisions are made rapidly with zero to minimal overlapping issues and to promote a unified, well-synchronised advance towards the common objective.
  • Set objectives then make sure they are met by guiding your key personnel in coordinating activities across projects.
  • Design or utilise existing financial models such that they adhere to your enterprise’s financial policies.
  • Develop procedures for reporting expenditures specific to the programme.
  • Establish the programme infrastructure, including
    • The appropriate technical environment and tools (e.g. hardware, software, communication, and other IT-related items)
    • IT staff and administrators
  • Evaluate your enterprise’s current IT architecture to determine whether it will suffice to achieve your objectives. If it doesn’t, propose options you can take to meet what is required.
  • Plan out activities that should take place in different levels in the organisation.
  • Implement a periodic review of the programme progress as well as of interim results to ensure everything is aligned with the strategic outcome.

Programme and Project Reviews

Whether we’ve helped you set up your programme or you did it on your own, time will come when you’ll need to know whether everything is going as planned. If it appears like the entire programme is going smoothly, chances are, something’s going awfully wrong somewhere. Remember, even the most well-planned projects and programmes are still under the mercy of unforeseen variables.

We’ve got highly specialised reviews for either projects or an entire programme. We’ll be able to provide you answers to questions like:

  • Are all projects aligned with the programme’s intended direction?
  • Are the people working on your projects as focused with the business rationale as they have been with meeting deadlines and utilising resources?
  • Where are your risks and exposures? How can they be remedied?
  • Is the project viable at all?

We understand how your staff would want to function normally as quickly as possible. Rest assured, our programme and project reviews are conducted swiftly and efficiently so that both interruptions and oversights are brought to a minimum.

After we’re done, you can expect a detailed quantitative assessment of your programme and/or projects’ status.

Basically, we’re not here to find mistakes; we’re here to help you find ways to correct them. If a project rescue is required, we’ll be the first to lend a hand.

Project Rescue

Believe it or not, many of our clients approached us not before or during their project’s planning stages. But rather, after having gone through sloppy execution, when they end up losing control. In other words, we’re usually at the receiving end of the distress signal, after they’ve punched the panic button.

While obviously this isn’t the ideal time to seek the aid of any expert because it means you’ve incurred unnecessary losses already, all is not yet lost. If the appropriate remedial actions are taken in a timely manner, you can still achieve highly acceptable end results.

In fact, in most of our experiences with project rescue operations, we’ve been able to put projects back on track – just the way the planners wanted them to be. We’ll also help you devise airtight strategies to prevent your project from going astray again.

At the end of our project rescue,

  • You’ll regain complete control
  • Milestones will be reached as planned
  • Requirements will be accomplished, and
  • The project will be realigned with ideal business directions

Project Governance Processes

Constructing a firm underlying structure is essential in any organisation. So before we’ll institute project management, we’ll do the following first.

  • Set up a PMO or Project Management Office to ensure, among others, that
    • Utilisation of facilities, budgets, technical support and other resources will be well coordinated
    • Work products can be tracked and reviewed
    • Issues regarding methodology and processes will be given appropriate attention
    • Training can be organised
    • Project management discipline be instilled in the IT department
  • Establish a steering committee to oversee the implementation of IT and business strategies
  • Fill up slots for a project manager, IT executive and a business sponsor and define the roles of each
  • Infuse project management practices to all affected units of the enterprise

Establishing PMOs, steering committees and other management structures is the easy part. Many organisations spend so much in order to create the structures related to project management, only to find out later that the effort has been all for naught. That’s why we won’t end there. Our objectives will therefore include the following:

  • To plant and cultivate an environment appreciative of project governance i.e. one that does not project it as just a bunch of bureaucratic processes and protocols.
  • To establish an organisational culture that starts at the top.
  • To make everyone involved understand that the power of project governance still lies in the hands of those who will ultimately implement it.

A project-driven enterprise is never propelled by a single project. Since multiple projects require a more complex governing structure, you’ll need to understand the intricacies of programme management.

How COBIT helps you achieve SOX Compliance

First released way back in 1996, COBIT has already been around for quite a while. One reason why it never took off was because companies were never compelled to use it ? until now. Today, many CEOs and CIOs are finding it to be a vital tool for achieving SOX compliance in IT.

Thanks to SOX, COBIT (Control Objectives for Information and related Technology) is now one of the most widely accepted source of guidance among companies who have IT integrated with their accounting/financial systems. It has also gained general acceptability with third parties and regulators. But how did this happen?

Role of control frameworks in SOX compliance

You see, the Sarbanes-Oxley Act, despite having clearly manifested the urgency of establishing effective internal controls, does not provide a road map for you to follow nor does it specify a yardstick to help you determine whether an acceptable mileage in the right direction has already been achieved.

In other words, if you were a CIO and you wanted to find guidance on what steps you had to take to achieve compliance, you wouldn’t be able to find the answers in the legislation itself.

That can be a big problem. Two of your main SOX compliance obligations as a CEO or CIO is to assume responsibility in establishing internal controls over financial reporting and to certify their effectiveness. After that, the external auditors are supposed to attest to your assertions. Obviously, there has to be a well-defined basis before you can make such assertions and auditors can attest to anything.

In the language of auditors, this ?well-defined basis? is known as a control framework. Simply put, once you certify the presence of adequate internal controls in your organisation, the external auditor will ask, ?What control framework did you use??

Knowing what control framework you employed will help external auditors determine how to proceed with their evaluations and tests. For your part, a control framework can serve as a guide to help you work towards specific objectives for achieving compliance. Both of you can use it as a common reference point before drawing any conclusions regarding your controls.

But there are many control frameworks out there. What should you use?

How SOX, COSO, and COBIT fit together

Fortunately, despite SOX?s silence regarding control frameworks, you aren’t left entirely to your own devices. You could actually take a hint from the SEC and PCAOB, two of the lead organisations responsible for implementing SOX. SEC and PCAOB point to the adoption of any widely accepted control framework.

In this regard, they both highly endorse COSO, a well-established internal control framework formulated by the Committee of Sponsoring Organisations of the Treadway Commission (COSO). Now, I must tell you, if you’re looking specifically for instructions pertaining to IT controls, you won’t find those in COSO either.

Although COSO is the most established control framework for enterprise governance and risk management you’ll ever find (and in fact, it’s what we recommend for your general accounting processes), it lacks many IT-related details. What is therefore needed for your IT processes is a framework that, in addition to being highly aligned with COSO, also provides more detailed considerations for IT.

This is where COBIT fits the bill.

How COBIT can contribute to your regulatory compliance endeavors

COBIT builds upon and adheres with COSO while providing a finer grain of detail focused on IT. You can even find a mapping between COBIT IT processes and COSO components within the COBIT document itself.

Designed with regulatory compliance in mind, COBIT lays down a clear path for developing policies and good practice for IT control, thus enabling you to bridge the gap between control requirements, technical issues, and business risks.

Some of the components you’ll find in COBIT include:

IT control objectives

These are statements defining specific desired results that, as a whole, characterise a well-managed IT process. They come in two forms for each COBIT-defined IT process: a high-level control objective and a number of detailed control objectives. These objectives will enable you to have a sense of direction by telling you exactly what you need to aim for.

Maturity models

These are used as benchmarks that give you a relative measurement stating where your level of management or control over an IT process or high-level control objective stands. It serves as a basis for setting as-is and to-be positions and enables support for gap analysis, which determines what needs to be done to achieve a chosen level. Basically, if a control objective points you to a direction, then its corresponding maturity model tells you how far in that direction you’ve gone.

RACI charts

These charts tell you who (e.g. CEO, CFO, Head of Operations, Head of IT Administration) should be Responsible, Accountable, Consulted, and Informed for each activity.

Goals and Metrics

These are sets of goals along with the corresponding metrics that allow you to measure against those goals. Goals and metrics are defined in three levels: IT goals and metrics, which define what business expects from IT; process goals and metrics, which define what the IT process should deliver to support It’s objectives; and activity goals and metrics, which measure how well the process is performing.

In addition to those, you’ll also find mappings of each process to the information criteria involved, IT resources that need to be leveraged, and the governance focus areas that are affected.

Everything is presented in a logical and manageable structure, so that you can easily draw connections between IT processes and business goals, which will in turn help you decide what appropriate governance and control is needed. Ultimately, COBIT can equip you with the right tools to maintain a cost-benefit balance as you work towards achieving SOX compliance.
