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.

Directions Hadoop is Moving In

Hadoop is a data system so big it is like a virtual jumbo where your PC is a flea. One of the developers named it after his kid?s toy elephant so there is no complicated acronym to stumble over. The system is actually conceptually simple. It has loads of storage capacity and an unusual way of processing data. It does not wait for big files to report in to its software. Instead, it takes the processing system to the data.

The next question is what to do with Hadoop. Perhaps the question would be better expressed as, what can we do with a wonderful opportunity that we could not do before. Certainly, Hadoop is not for storing videos when your laptop starts complaining. The interfaces are clumsy and Hadoop belongs in the realm of large organisations that have the money. Here are two examples to illustrate the point.

Hadoop in Healthcare

In the U.S., healthcare generates more than 150 gigabytes of data annually. Within this data there are important clues that online training provider DeZyre believes could lead to these solutions:

  • Personalised cancer treatments that relate to how individual genomes cause the disease to mutate uniquely
  • Intelligent online analysis of life signs (blood pressure, heart beat, breathing) in remote children?s hospitals treating multiple victims of catastrophes
  • Mining of patient information from health records, financial status and payroll data to understand how these variables impact on patient health
  • Understanding trends in healthcare claims to empower hospitals and health insurers to increase their competitive advantages.
  • New ways to prevent health insurance fraud by correlating it with claims histories, attorney costs and call centre notes.

Hadoop in Retail

The retail industry also generates a vast amount of data, due to consumer volumes and multiple touch points in the delivery funnel. Skillspeed business trainers report the following emerging trends:

  • Tracing individual consumers along the marketing trail to determine individual patterns for different demographics and understand consumers better.
  • Obtaining access to aggregated consumer feedback regarding advertising campaigns, product launches, competitor tactics and so on.
  • Staying with individual consumers as they move through retail outlets and personalising their experience by delivering contextual messages.
  • Understanding the routes that virtual shoppers follow, and adding handy popups with useful hints and tips to encourage them on.
  • Detecting trends in consumer preferences in order to forecast next season sales and stock up or down accordingly.

Where to From Here?

Big data mining is akin to deep space research in that we are exploring fresh frontiers and discovering new worlds of information. The future is as broad as our imagination.?

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.

How FieldElite helps Plumbers

While most people think that running a plumbing business is a very easy job, things are a bit different on the ground. The job goes beyond the dropping by a client’s home and fixing a few pipes. In addition to the actual plumbing work, a plumbing business also involves managing quotes, invoicing customers, dispatching field service workers, and accounting, among others. Undertaking all these operations manually is extremely demanding. Besides the tedious work that it is, you’re likely to end up with a ton of errors. 

However, you can overcome these challenges by employing technology. The use of field service management software allows you to automate tasks. Consequently, you no longer have to deal with paperwork, delayed responses to customer requests, or double assignment of tasks.

If you’re wondering which field service management software to use, FieldElite is your best bet. FieldElite is feature-rich, and it gives you way more than the simple automation of the daily operations of your plumbing business.  

Below are some of the top benefits you’ll reap by using FieldElite to run your plumbing venture.  

Convenient Scheduling

Scheduling is an important aspect of the plumbing industry. Just like other field techs, plumbers would require tasks to be dispatched on time, which is only made possible by proper scheduling. With FieldElite, managers can easily schedule single and recurring tasks for the right plumber in a matter of seconds. 

On the other hand, plumbers can also view the available jobs and job information in the FieldElite easy to use App that’s available for Android, and confirm scheduled jobs. They can also accept these jobs using their smartphones and respond to service requests instantly.

Apart from getting the scheduled tasks, the FieldElite scheduling and dispatch feature is integrated with GPS functionality so that plumbers can get information on where to go next, and the optimal route to take from their mobile phones. 

The scheduling and dispatch feature also gives plumbers the information on the specific tools required for the job to allow them to get the tools in between appointments and schedules. 

Central Data Storage

Just like other field service industries, plumbing also involves big data. Handling data manually would mean more errors for your plumbing business, which will only impact negatively on your business. To eliminate such errors, go paperless with FieldElite. 

You can view everything from one place with FieldElite?s dashboard feature, including information about your plumbers and the scheduled tasks. On the other hand, your plumbers can access job details and the pending tasks from a central place. 

Plumbers can also get service requests from customers on the FieldElite mobile app from wherever they are. All the requests are stored in a central place, making the response to customer requests easier. The end result is satisfied customers, opening doors for return orders. 

In case of an update, all plumbers receive notifications at the same time and, where necessary, respond promptly to the requests. They can update the office instantly with job status changes from a central place. 

Convenient Reporting

Reporting is part of the tasks that plumbers have to do after completing the assigned job. As a manager, you expect your plumbers to keep you updated on the status of each assignment. Reporting on paper is time-consuming, and that’s why you need the services of FieldElite. 

With FieldElite reporting feature, sending over completed job reports is only a few clicks away. Plumbers can generate reports on the mobile app and keep the office staff updated on the status of the job. Using FieldElite, you can capture customer signatures and add attachments to the job status and send them instantly using the mobile app available on Android. 

Since they can do instant reporting via the mobile app, the plumbers can proceed to attend to new service requests as soon as they’re done without having to first come back to the office to submit their reports. 

Effective Communication

Timely communication is very essential if you’re working with field technicians. Since you’ll not always be with them in the field, it’s always important to establish a proper communication channel to ensure information reaches your plumbers in time. Here, you can get much more with FieldElite, including communication automation to remind customers of appointments.

With FieldElite field service management software, plumbers receive notifications through the mobile app. The notifications can be for anything from new task requests, requests for alterations, emergencies, and more. On the other hand, office-based staff gets to access the reports once the plumber completes their given task. 

That means the plumbers in the field and the office-based team gets communication instantly, enabling them to see and manage their workloads. For this reason, plumbers can complete multiple tasks within a short time, thus improving their overall productivity.

Scalability

The biggest question for most entrepreneurs when they want to buy management software is scalability. Businesses grow and incorporate new activities that would also require to be managed from a centralised system. Where that’s not possible, the business would have to move all their information from one system to a more robust one. 

With FieldElite, however, you’re safe. It works perfectly well for startups as well as large-sized plumbing businesses. It allows you to focus on the areas that your organisation covers now, but also lets you add new areas as you introduce them into your business. Moreover, FieldElite is also receiving regular updates to that bring it up-to-speed with new technologies and new ways of doing things, meaning that your business will be in a position to take advantage of the latest and more productive features. 

From the benefits mentioned above, it’s quite clear that your plumbing industry greatly needs the services of a field service management software. Your plumbers too need easier time working on their assigned tasks, adding to the reasons why you need to integrate FieldElite in your plumbing business.
