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.

Vendor Selection

When shopping for an IT solution for your enterprise, there are two things you should scrutinise: the product (or service) itself and its vendor. Many times, companies overlook the importance of the latter, giving the reason that “it’s only the product we need”.

Wrong.

What about after-sales technical support and training? Ok, so you have an in-house team with the required competency for that IT solution in question… not that I believe it’s reasonable basis to pass up on the expertise that the vendor can provide. How about upgrades, patches, and documentation?

Still unperturbed? Here’s one factor that you may not have started to consider – What happens to your product if the vendor goes bankrupt or gets swallowed by a merger and acquisition? Surely, you no longer believe this is far from possible, do you?

But how are you supposed to know the financial stability of each vendor or whether it is an acquisition target? Well, you can either conduct your own research or you can leave that up to us. Part of our job includes not only establishing linkages in the industry but also being in-the-know on such relevant information.

Evaluation of Business Needs

You can’t separate vendor selection from the process of choosing the desired IT tool. That’s why our vendor selection services starts by defining exactly what your business needs are.

Once we’ve pinned down your needs, we can then narrow down the list of possible IT solutions. Only then can we proceed with the main vendor selection process.

Have you ever been caught in a situation wherein you thought you knew what you wanted, only to end up realising it’s not what you were looking for after all? We’re here to make sure you don’t get caught in that kind of situation when choosing an enterprise-class IT solution.

With the TCO (total cost of ownership) of such solutions typically running up to hundreds of thousands of euros, you can’t afford to arrive at what you really want by way of trial and error.

These are the things you stand to benefit the moment we start working with you:

  • Thorough assessment of your IT needs. We’ll consult the people in your organisation who’ll be affected the most in order to obtain a clear picture of what your specific needs really are. Most IT solution purchases are made with very little consultation that, after installation, many of the end users don’t benefit at all.
  • Minimal interruption during assessment. As with all our other services, we see to it that the interruptions we make are absolutely necessary. So the moment we start with our work, you can still continue with yours.
  • Insightful suggestions of the required IT solution. You still know your business better. So even after we’ve gone through the assessment and given our recommendations, the decision as to what IT tool should be pursued will still be up to you. The difference now is, you’ll be making a decision based on expertly gathered information put forward in an insightful proposal.

Request and Evaluation of Vendor Proposals

With so many IT solutions companies mushrooming, it is becoming more difficult to keep track of them, their specialities, strengths, and weaknesses.

Companies selling best-of-breed products may be relatively easy to spot. But there are also other attributes that are equally important but not as well publicised. For instance, which companies offer better quality management philosophies? Which companies have strategic visions running parallel to yours? Which of them possess implementation capabilities that can cater to your rapidly growing IT requirements?

Vendors who answer positively to these queries need to be given the appropriate importance in the selection process. We see to it that these and other relevant attributes are factored into our scorecards and evaluation processes.

These are the things you can look forward to when you grant us the opportunity to serve you.

  • Experience is a vital item in our vendor selection criteria. Our vast knowledge of the reliable players in the industry will lead you to experienced vendors who can hit the ground running from day one and continue with the same vigour onward.
  • We can help you draw positive response for each of your Request For Proposals (RFPs) or Request For Information (RFIs). Did you expect these vendors to be enthusiastic in sending out proposals each time you asked them to? Think again. You’ll have to persuade them first of your sincerity to become a potential customer. With our help, your RFPs will make preferred vendors see “opportunity” written all over.
  • No need to go “Eany, meeny, miny, moe”. Deciding which vendors should move up in the selection process can take up a lot of time if you don’t know which criterion should be given more weight. Our scorecards are designed to collect the most relevant information and to generate results that will help you decide on these matters at a glance.

Interview, Negotiation, and Monitoring

As soon as you start getting positive response to your Request For Proposals, the interview process should be next. It’s at this point that vendors can present and highlight their strengths while we try to glean as much information of their true capabilities as well as their dedication to the project.

Some companies can provide proof-of-concepts and we may require them as part of the interview process. This will not only give us a better idea as with regards to their product’s capabilities, but also to their level of expertise on the solution in question.

  • We’ll help you set up the interview process and organise the evaluation committee. Members of the committee will typically include representatives from each department that will be affected by the new technology, which we would have already identified during our Evaluation of Business Needs.
  • Since our scorecards are designed to expedite the filtering and selection process, you may eventually be able to choose the finalists yourself. However, in the event that two or more vendors turn out evenly matched, we’ll help you identify the better company.
  • We’re very familiar with the price ranges of various IT solutions, including the effects on price of certain variables. As such, we can tell you whether a product’s price tag is justified or not.
  • Our exceptional familiarity on both the IT industry and the entire negotiation processes itself will give you the edge when it’s time for us to haggle for the best bang for the buck.
  • After the contract is awarded, we’ll even be on hand to monitor whether deliverables are handed over and milestones are achieved as promised.
Without Desktop Virtualisation, you can’t attain True Business Continuity

Even if you’ve invested on virtualisation, off-site backup, redundancy, data replication, and other related technologies, I?m willing to bet your BC/DR program still lacks an important ingredient. I bet you’ve forgotten about your end users and their desktops.

Picture this. A major disaster strikes your city and brings your entire main site down. No problem. You’ve got all your data backed up on another site. You just need to connect to it and voila! you’ll be back up and running in no time.

Really?

Do you have PCs ready for your employees to use? Do those machines already have the necessary applications for working on your data? If you still have to install them, then that’s going to take a lot of precious time. When your users get a hold of those machines, will they be facing exactly the same interface that they’ve been used to?

If not, more time will be wasted as they try to familiarise themselves. By the time you’re able to declare ?business as usual?, you’ll have lost customer confidence (or even customers themselves), missed business opportunities, and dropped potential earnings.

That’s not going to happen with desktop virtualisation.

The beauty of?virtualisation

Virtualisation in general is a vital component in modern Business Continuity/Disaster Recovery strategies. For instance, by creating multiple copies of virtualised disks and implementing disk redundancy, your operations can continue even if a disk breaks down. Better yet, if you put copies on separate physical servers, then you can likewise continue even if a physical server breaks down.

You can take an even greater step by placing copies of those disks on an entirely separate geographical location so that if a disaster brings your entire main site down, you can still gain access to your data from the other site.

Because you’re essentially just dealing with files and not physical hardware, virtualisation makes the implementation of redundancy less costly, less tedious, greener, and more effective.

But virtualisation, when used for BC/DR, is mostly focused on the server side. As we’ve pointed out earlier in the article, server side BC/DR efforts are not enough. A significant share of business operations are also dependent on the client side.

Desktop virtualisation (DV) is very similar to server virtualisation. It comes with nearly the same kind of benefits too. That means, a virtualised desktop can be copied just like ordinary files. If you have a copy of a desktop, then you can easily use that if the active copy is destroyed.

In fact, if the PC on which the desktop is running becomes incapacitated, you can simply move to another machine, stream or install a copy of the virtualised desktop there, and get back into the action right away. If all your PCs are incapacitated after a disaster, rapid provisioning of your desktops will keep customers and stakeholders from waiting.

In addition to that, DV will enable your user interface to look like the one you had on your previous PC. This particular feature is actually very important to end users. You see, users normally have their own way of organising things on their desktops. The moment you put them in front of a desktop not their own, even if it has the same OS and the same set of applications, they?ll feel disoriented and won’t be able to perform optimally.

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.
