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.

How Sustainable is Suez Environment

French-based Suez Environment works in the water and waste-management environment, with specific reference to water production, treatment, & pollution disposal, and waste treatment, recycling, incineration and site desensitisation. Its more than 65,000 employees distributed worldwide have participated in flagship projects like Renault’s goal of 95% reclamation of vehicle parts, and Lyonnaise des Eaux?s saving of 12 million cubic meters of water in a single year.

Suez Environment claims to have consistently increased the recovery rate of treated waste, decreased direct and indirect greenhouse gas emissions, and made significant inroads into the production of sustainable energy on behalf of its clients. But then surely that’s Suez Environment’s business, and with over 65,000 employees we are entitled to expect this. Given that there have been persistent allegations of privatised water distribution bumping prices up to the detriment of the poor, how effective is Suez Environment at practising what it preaches back home?

GDF Suez is its largest shareholder and includes it under its environmental and societal responsibility umbrella. This makes environmental performance an overarching goal alongside management systems, health and safety, risk and procurement, and ethics. Its environmental ambitions spin out into the following strategies:

  • Understand the interactions between our activities and the environment
  • Open dialogue with stakeholders and foster partnerships with them
  • Set quantitative and qualitative targets at all levels of the organisation
  • Achieve optimum balance between financial and environmental challenges
  • Be proactive; anticipate impacts on the environment and plan for them
  • Increase employee awareness through interactive training and education
  • Be constantly innovative; share successes within the organisation
  • Monitor progress continuously and publish measured results achieved.

These goals direct the Suez Environment management team?s attention towards optimising performance in key areas like greenhouse gases, energy management, renewable energy, biodiversity, responsible water management, pollution prevention and health and safety considerations.

Among numerous other examples, its waste incineration programs convert hazardous and conventional waste into heat used to generate electricity without requiring virgin carbon products. Elsewhere, the same energy warms market-gardening tunnels and work places on winter days.

Suez Environment uses sophisticated energy management software to analyse information that’s transmitted by data logging devices online. ecoVaro provides a similar service in the cloud. ecoVaro adapts to your requirements providing fresh insights to your business.

Outsourcing

Are you ready to outsource? Do you even need to outsource? We’ll help you answer those and other questions regarding outsourcing and your company.

Once we’ve determined that outsourcing will render your organisation more focused on your core competencies, more cost-effective, and more flexible, we’ll offer you the full spectrum of our services. Our specialists can assist you in every stage of the entire outsourcing life-cycle.

Starting from evaluating what can be outsourced, through finding the right outsourcing service provider, building the contract and agreements, getting everything in place, and managing the outsourcing relationship – we’ll be with you every step of the way.

Learn more about some of the outsourcing services we offer:

Outsourcing Contracts and Agreements

When an outsourcing project fails, both customer and service provider are quick to put the blame on the other party. But in most cases, the actual culprit was really just sitting there since day one – a poorly planned and implemented agreement.

We understand how costly and disruptive a failed outsourcing project can be for your business. That is why we put utmost attention to each contract and SLA (Service Level Agreement) that our customers enter into. This always reduces the likelihood of having unmet expectations, one of the major reasons why some outsourcing relationships fail.

We make sure that each agreement is fair, not only for our customers but also for the service providers themselves. Why? Because a disadvantaged provider will most likely end up delivering poor service as an offshoot of efforts to improve its profitability and ROI.

To accomplish this, we’ll thoroughly assess the infrastructure, resources, and expertise of your potential service provider to ensure they have the capability to meet your expectations. We’ll also make sure that their expectations are realistic and clear to you as well.

Here’s what you can expect from us when we start managing your outsourcing contracts and agreements:

  • A thorough assessment of your specific needs and the service provider’s profile to determine whether you have the right match before proceeding with any agreement.
  • Professional assistance when the time comes for you to discuss the scope of work, expected service levels, and when negotiating for appropriate pricing. We’ll also help you set up provisions for possible changes in the scope later on.
  • Expert counsel during drafting and finalisation of the contract and Service Level Agreements. Whenever applicable, we’ll help you propose penalties whenever service levels are not met and rewards when they are exceeded.
  • Regular reviews to determine whether everything agreed upon in the past, like pricing and service levels, are still realistic or competitive enough in view of current technological advancements and the prevailing social and economic environment.
  • Mediation expertise whenever the outsourcing project appears to be falling apart. We’ll work with you and the service provider to resolve conflicts and avoid the expensive exercise of having to terminate the contract. But if the best solution is to part ways, we’ll make sure you make an exit with the least disruption, missed opportunities and financial loss.

Application Outsourcing

I’m sure you’ve come to realise that to gain competitive advantage these days, you really need to invest in IT applications.

There are applications for enhancing your customer relationships, speeding up production, streamlining processes, advancing collaboration, protecting your systems from malware and many more. Selecting the right application, testing it, implementing it into your system, and then managing it can deviate resources which would have otherwise been used in other areas to build business value, increase profits, and enhance innovation.

Wouldn’t it be nice to unload yourself of the management processes which usually accompany IT applications? Actually, you can – through application outsourcing. Application outsourcing providers possess the expertise to either partially or fully assume responsibility of your IT applications.

Our job is to see to it that you link up with the provider who can best answer your needs. The overall proficiency of these providers spans both proprietary and opensource solutions, allowing them to cater to a wide range of preferences and budgetary limits. At the very least, they can provide professional support for well established applications.

If needed, they can develop applications for your organisation, taking charge of every step in the system development life-cycle: starting from system initiation, requirements analysis, through design, construction, acceptance and eventually to implementation.

Here are some of the benefits you can enjoy once we start managing your application outsourcing initiatives:

  • Freedom from time-consuming tasks such as installations, upgrades, configurations and repairs.
  • Reduced total cost of ownership (TCO).
  • 24/7 support from well-trained personnel. This can substantially cut downtimes caused by inexperienced troubleshooting.
  • The option to have your applications housed in more secure and reliable environments with much higher availability and much lower planned/unplanned downtimes.
  • Dedicated specialists who can focus on providing better regulatory compliance and risk mitigation initiatives.

Infrastructure Outsourcing

Keeping up with the competition nowadays usually requires technological advancements as well as the capability to manage and maintain the infrastructure that has to support them. These undertakings can suck your resources dry.

If you’re looking to reduce costs even while improving the performance of your networks, servers, databases, firewalls, desktops and mobile devices, you might want to consider IT infrastructure outsourcing among your top options. Infrastructure outsourcing service providers have the resources dedicated to a stable, secure, scalable and always available IT infrastructure.

Typical service provider facilities include data centrers equipped with high-speed networks, reliable power, dependable security, as well as provisions for upgrades, consolidation, disaster recovery, or even business continuity.

These providers employ specialists and staff who can manage and maintain all of these for you. While your provider juggles your core IT-related tasks, you can keep your eye on the ball and refocus on your company’s business goals.

Here are some of the benefits you can enjoy out of infrastructure outsourcing:

  • Freedom from time-consuming tasks such as installations, upgrades, configurations and repairs.
  • Since service providers, who are expected to have better horizontal and vertical scalability, will deal with the technological intricacies, your company’s strategic development initiatives can proceed unhampered.
  • Greatly reduced electricity expenses as a result of consolidation.
  • Easier, faster, cheaper, and more reliable disaster-recovery solutions through virtualisation.
  • Lesser risks of disruptions caused by power outages, cyber attacks, or Internet connection downtimes.

Business Process Outsourcing

With the sheer number of business processes your company has to attend to, it wouldn’t be surprising if you rarely have room to innovate.

Through business process outsourcing, we can free a considerable part of your financial and manpower resources which are currently focused on routine activities. With more resources to drive innovative initiatives, you’ll be able to accelerate production, improve customer service, enhance overall business value, and arrive at a stronger bottom line.

Some of the business processes that may be outsourced include data entry, finance and accounting, form processing, procurement, and HR, among others. If you’re interested in finding answers to the what, how, who, and where of BPO, specific to your organisation, we’ll be happy to enlighten you.

Here are some of the benefits you can enjoy once we start managing your BPO initiatives:

  • Professional guidance to ensure that your BPO undertakings will really result in substantial savings and significant improvements to your organisation’s business value.
  • Careful monitoring of service levels to ensure faster turnaround, accurate data, and high quality outputs.
  • Expert evaluation of information handling processes to guarantee full confidentiality.
  • Professional and unbiased management dedicated to establishing a strong, reliable, and fruitful relationship between you and your provider.
How to Improve Corporate Efficiency through IT

When revenues are low, what do you do to improve your profit? Obviously, those same revenues should at least remain the same. So, the objective would be to deliver the same products and services for less cost. More for less. Such is the essence of corporate efficiency.

There are many things that can make a company inefficient. There are outdated procedures, poor coordination between departments, managers? lack of business visibility, and prolonged down times, to mention a few. As a company grows, these issues get more severe.

You can overcome all these by deploying the right IT solutions. But don’t IT solutions increase spending instead? Au contraire. The last couple of decades have seen the rise of IT solutions that help companies’realise obvious cost savings in no time.

Streamline processes and keep departments in-sync

Company inefficiencies are largely due to outdated systems and procedures. These systems and procedures were not built for the dynamic and complex business environments of today that are being shaped by increasingly onerous regulations, fierce and growing competition, significant economic upswings and downturns, new battlefronts (like the Web) and logistical strategies (like outsourcing), and IT-savvy crooks.

So when your employees force outdated systems to meet today?s business demands, they’re just not able to deliver. At least not efficiently.

Another major cause of inefficiency is the discordance among departments, business units, and even individual staff members themselves. There are those who still use highly personalised spreadsheets and other disparate applications, which make data consolidation take forever and the financial close a perennial headache.

Costly devices like mobile phones, netbooks, and tablet PCs, which are supposedly designed to provide better communication, are not fully maximised. If these are subsidised by the company, then they also contribute to company inefficiency.

One way to deal with these issues is to deploy server based solutions. By centralising your IT system, you can easily implement various improvements that can pave the way for better communication and collaboration, stronger security, faster processes and transactions, and shorter down times for troubleshooting and maintenance. All these clearly translate to cost savings.

Gain better visibility

Corporate efficiency can be improved if your decision makers can make wise and well-informed decisions, faster. But they can only do this if reports they receive from people down the line are timely, accurate, and reliable. Basically, data should be presented in a way for managers to gain quick insights from.

If your people take too much time scrutinising, interpreting, and reconciling data, you can’t hope to gain a significant competitive advantage. Equally important to managing an ongoing project is the speed at which you make a go/no go decision to start or stop a project. A wise, quick decision will help you avoid wastage.

The same holds true when making purchases and investment decisions. It’s all about quickly eliminating waste and investing only on those that will give you fast, positive returns.

Clear business visibility will allow managers to allocate resources where they are most effective, to pinpoint what products and services being offered are more profitable, and to identify which customers are giving better business from an overall perspective.

These are all possible with business intelligence. We know, we know. You’ll say BI solutions will force you to break the bank. Not anymore. At least, not all. There are already two main types of BI solutions: on-premise and SaaS. The latter will generally cost you less.

Of course, each type has its own advantages, and you’ll really have to look into the size of your organisation, the number of source systems your decision-making platform is connected to, integration requirements, budget, etc. to make sure you get the most out of your investment.

But IT solutions cost an arm and a leg

Again, not anymore. These days, you can find IT products that are faster, more functional, and more powerful than their predecessors at a fraction of the cost. When it comes to getting more affordable IT products and services, you now have many options.

For example, you can turn to open source solutions to save on license costs. These solutions are typically backed by vibrant and helpful communities where you can find an extensive source of technical support – many of which are for free. With popular open source products, you can easily tap from a large pool of developers with affordable rates any time you want to make system enhancements or customisation.

On another front, virtualization solutions allow you to save on CAPEX and OPEX by eliminating certain expenses normally used for setting up infrastructure or buying hardware and maintaining them. Server virtualisation, for instance, will allow you to consolidate servers and put them together into just one machine, while desktop virtualisation will enable you to eliminate unproductive hours associated with desktop down times by allowing you to redeploy a malfunctioning desktop very quickly.

Closely related to those are cloud-based solutions like SaaS (Software as a Service), IaaS (Infrastructure as a Service), and DCoD (Data Center on Demand). SaaS and IaaS will help you realize savings in acquisition and maintenance costs for software and hardware, while DCoD?s scalable services allow you to request for additional capacity, power and storage only as you need them, thus making you spend only according to your current infrastructure requirements.

Like we said, there are many, many options out there just waiting to be tapped.
