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.

What is Business Intelligence?

How well do you know your customers? That is, can you actually pinpoint which among them are you most profitable with and which are making you spend more? Are you content with the accuracy of your forecasts and market predictions? Do you feel you’re spending more on legal costs and regulatory compliance than you should?

Your IT department may be handling these concerns pretty well but perhaps you’d like to know how you can further improve things.

What we’ve got is an IT solution wrapped in a fancy name called ‘Business Intelligence’ or BI. If you think that’s too strong a term, we invite you to read more below, then you be the judge.

Dashboards – Determine the health of your business at a glance

Most drivers rarely make use of their car’s dashboard. After all, you can still reach your destination by just using the steering wheel, pedals, gear stick and so on. But that’s not exactly the most efficient way to drive, right?

If you want to save on fuel, you’ll want to glance on the RPM and speedometer from time to time. You might also want to utilise the trip meter to determine which route is the shortest to a given destination. Other dashboard components like the fuel gauge, tire pressure gauge, engine temperature indicator, and volt meter can likewise provide information about your car’s health.

The same concept applies to business management. If you want to run your business intelligently, you can make use of BI dashboards. These are tools in a typical business intelligence package that will allow you to determine the health of your business via a set of smartly configured gauges and other intuitive graphical representations.

So that, literally, at a mere glance, you’ll already know whether various units in your company are working efficiently. A dashboard will also give you instant feedback of the strategies you’ve recently implemented; to let you know if things are working as planned.

If you want more information than a dashboard can provide, our BI packages also include highly customised reports.

Reports that help you decide faster

Dashboards are great for getting valuable information at a glance but they won’t tell you everything. For more details, you’ll need to view highly customised reports. Our reports are tailor made for each user. We see to it that, by default, each person gets the information he needs the most.

If you belong to the sales department, you normally won’t need a presentation of the data that is appropriate for people in accounting. That way, you don’t spend time filtering. Instead, you and your people can move on to making well-informed decisions.

Our BI systems make use of your vast collection of data to provide reports that will organise your regulatory requirements and call your attention to approaching deadlines. The same system will provide the right information for your people on the field. If your team members are equipped with smart phones and Pocket PCs, they can retrieve whatever it is they need to know to close deals, make sales, and serve clients faster than the competition.

Generating logical information from disparate sources of data scattered over an enterprise-wide organisation is no easy task. But we’ll make it look simple. That’s because we’ve got the expertise to bring it all together into a robust data warehouse and to extract them in the form of reports and dashboards through OLAP.

OLAP and Data Warehousing – Powering the generation of actionable information

Want to know how to generate reports with the highest degree of accuracy and reliability? In theory, what you need is a single repository or a data warehouse. That is, order receipts, sales invoices, as well as customer & supplier data is integrated with regulatory details, personnel data, and others. These are all specially organised for future reporting and analysis.

However, data, no matter how all-embracing, is useless until it is processed into actionable information. Through OLAP or Online Analytical Processing, you can seamlessly collect all relevant data from your vast repository to answer queries like “What is our company’s profitability for the 2nd quarter in all identified key cities for our top-of-the-line products?”.

The strength of OLAP lies in its inherent ability to perform data analysis and very complex calculations, thus enabling it to return complex queries much faster than other database technologies. It is therefore suitable for very large data sources, i.e., data warehouses.

Dashboards and reports will only give your organisation the edge if the information retrieved is reliable, fast, and accurate – exactly the kind OLAP is so good at.

Mobile BI – Step back and see the big picture anytime, anywhere

Spreadsheets are great for displaying detailed information. However, in today’s highly competitive market, retrieving information that matters the most in the shortest possible time is vital in maintaining a sizeable lead over the competition. To step back and see the big picture, you’ll need insightful tools like dashboards and automatically generated reports.

Reports can be beamed to mobile devices such as smart phones and Pocket PCs. They can also be viewed on eBook readers as well. You can also do the same tasks with spreadsheets. But imagine how you’d need to scroll over a large spreadsheet on any of these mobile devices just to know which customer in your current location has performed well over the last month.

If you really want to make quick, well-informed decisions, BI dashboards for mobile devices is the way to go. You can make use of various business objects such as drill-able charts, performance metrics, and metric trend graphs to make crucial decisions even when on you’re in the field.

Quality Assurance

 

There is a truism that goes “The bitterness of poor quality is remembered long after the sweetness of low price has faded from memory”.

While every consumer can probably relate to this idea, business enterprises offering goods and services are the ones that should heed this the most.

Quality Management Systems

The concept of quality was first introduced in the 1800’s. Goods were then still mass-produced, created by the same set of people, with a few individuals assigned to do some “tweaking” on the product to bring it to acceptable levels. Their idea of quality at that time may not have been that well-defined, but it marked the beginnings of product quality and customer satisfaction as we know it now.

Since then, quality has developed into a very basic business principle that every organisation should strive to achieve. Yet while every business recognises the importance of offering product and service quality, it is not something that can be achieved overnight.

If you’ve been in any type of business long enough, you should know that there is no “quick-fix” to achieving quality. Instead, it is an evolving process that needs to be continually worked on. And this is where the importance of having a workable Quality Management System (QMS) in an organisation comes in.

Whatever Quality tools and processes you need to implement the change needed in your organisation, we can help you with it. We are ready to work in partnership with your team to develop strategic systems which will produce significant performance improvements geared towards the achievement of quality.

What is a Quality Management System?

A Quality Management System is defined as the set of inter-related objectives, processes, and operating procedures that organisations use as a guide to help them implement quality policies and attain quality objectives.

Needless to say, the ultimate goal of every quality management system is to establish quality as a core value of the company among all employees, and across all products and services. Why? Because quality services make for happy customers, and satisfied customers ensure continued business for the company.

A Quality Management System does not stop with simply having a set of guidelines that the leaders of a company can easily have their organisation members accept and adhere to. Rather, effective QMS can be implemented when management provides a culture of pride and patience, which will inspire acceptance of individual and group responsibility.

In this manner, not only the heads of the organisation but the employees as well, will develop the desire to achieve company goals that will benefit:

  • All contributing teams;
  • The customers; and
  • The company as a whole.

Field service and improved visibility

A manager is someone who has control over a company. They are given the responsibility of overseeing what the company does and making important decisions. The manager is the most important person in the empire and needs to be in the know at all times. Not what happened a day ago but in real-time and from any place.

Information is necessary for this to happen. It needs to be concise, brief and straightforward. Ideally, access to job status, location information, customer information, notifications and location information should be on the palms of their hands.

To sum it all up, there should be fluid communication among personnel in the field. Information should be accessed easily from one place as it flows to another to maintain steady two-way communication. This is possible with automation meaning that no amount of data will be left unseen or unused because of paperwork that was never handed over or looked into, reducing the chance of misinformation or missing information to a minimum.

Ways improved visibility will help your business through Field Service

Organisations using field services will agree that improved visibility has more business benefits and the real question is what aspect needs improving rather than discussing the benefits.

Real-time visibility

Managers need to be in the know from anywhere at any time. The manager needs information about the company. The need not to be physically present to have an idea of what’s going on. They should know everything at all times, from what was planned for the day to real-time events.

All this information should be easily accessed from one central point and should contain everything about the company and other relevant information.

Extending the back office into the field

This two-way communication is virtually irreplaceable. At any time, the information should flow among technicians in the field and those in the back office. This will help to have a better idea of how to manage the workload and come up with solutions to some work-related issues.

Everyone in the team should be informed and be up to speed about real-time events. Keeping everyone updated improves visibility because they can make updates and decisions based on the kind of information they get.

No more lost paperwork

Managing paper trail can be quite a hassle for organisations. With tons of workload, there can be many delays meaning that some information might be missed or forgotten. People might also choose not to turn up for work for days on end and can affect how much info is processed. Some work can be left undone, and work not invoiced.

When organisations use field service management services, information is fed only once and everything else is done automatically. Say goodbye to lags or relying on last month?s data. Work will move faster because people will have more time to focus on important things rather than chasing an endless paper trail.

Business intelligence

Field service management technology will let you know what is being done in the field and with such an abundance of data, will make sound decisions for the business.

Every decision is hinged on cold facts. Information needs to be easily accessed and filtered into the right categories so that sound business decisions are made from the collected data.

Growing revenue

The abundance of real-time information and improved visibility can determine whether a business will grow or not. Each piece of information can show trends that are critical for any business to improve. Trends show how each sector is doing and sheds more light into specific areas that need a total overhaul. This may include improving customer service, products on retail or hiring more technicians.

Without information, a company is one step closer to going out of business. Every action should be geared to increase the revenue and this starts by making the right choices.

Visibility when working offline

Working offline is an issue that can affect visibility. Sometimes agents will need to work in areas that have little network coverage or are deep down working in tunnels or are around heavy machines and turbines. Field service solutions are built for the mobile environment and for workers who may find themselves in non-connected areas so that they can still use their device while offline. This makes sure that there is no loss of information while working in-field

Time-saving

Certainly, business is constrained to its environments and if the demand changes it should prove to be flexible enough to adjust to changes as they happen. Field service solutions operations like schedule need to update instantly. Once activities start rolling, nothing should create lags in the schedule so that operations flow seamlessly at all time.

Field workers can then make updates and document changes easily on the job site directly on their device by using responsive site menus, drastically saving time while feeding data and complete orders.

Improved customer service

It is not a clich? to say that the customer is always right. With real-time information, both field service and back-office technicians can improve customer relations and satisfaction. With a unified system of sharing information like the ERPs and CRMs, the field officer can know more about specific clients, their history and other data to know more about what should be done in current and future orders. This means that better decisions will be made for each customer.

How improved visibility benefits different parts of the organisation

Improved visibility in all areas of the business makes information more accessible. Here are some of the benefits that various sects of a business can get from improved visibility.

? The business owner
The manager owns the company and can access all information with just a single tap. A lot of data can be used to analyse the health of the venture. This includes revenue, inventory, customer surveys, employee hours, invoices and customer data.
Profitability is increased by putting more emphasis on customer satisfaction and improving the quality of end products and services.

? The service manager
The service manager can see what is going on in the field in real-time, and look into measures that can improve the productivity of staff members in various departments.
And with workflow automation, time-saving is at the maximum because there is less paperwork consequently improving scheduling and job completion rates.

? Service administrator/ dispatcher
For the team in the office, they can assign tasks faster. Scheduling is automatically done and updated in real-time. It eliminates the need for paperwork and leaves more time to be productive on other errands.

? The field technician
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.

? HR
Live information can be used to track certain orders, the time it takes to complete orders, and the number of staff required in the organisation. Such data can be used in HR to reduce payroll errors and erroneous overtime costs.

? Finance
Field service management software can also benefit the finance team by automation of invoices. A work order can be tracked from start to the end and invoiced immediately to retain faster payments. Relevant data can be used to track revenue and expenditures, and costs.

Real-time visibility gives a company many solutions to manage the workload. In the end, visibility is also useful in increasing revenue and a smooth transition of information for the company.
