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.

IT Systems Implementation

Are you ready to find out how your newly accepted IT system fares in the real world? Although a rigorous Acceptance testing process can spot a wide spectrum of flaws in a newly constructed IT system, there is no way it can identify all possible defects. The moment the IT system is delivered into the hands of actual end users and other stakeholders, it is effectively stepping out of a controlled and secure environment.

Thus, it is during this phase wherein issues having direct impact on the business can arise.

It is our duty to ensure that the Systems Implementation phase is carried out as thoroughly, professionally, and efficiently as possible.

Thoroughly, because we need to include all relevant data and other deliverables, eliminate hard-to-detect miscalculated results, and substantially reduce the probability of business and mission critical issues popping up in the future;

Professionally, because it is the best way to address the sensitive process of turning over a new system to users who have gotten used to the old one;

And efficiently, because we want to minimise the duration over which all stakeholders have to adapt to the new system and allow them to move on to the process of growing the business.

Preparation

Louis Pasteur once said, “Luck favours the mind that is prepared.”

While we certainly won’t leave anything to chance, we do put substantial weight on the Preparation stage of Systems Implementation. We’re so confident with the strategies we employ in Preparation, that we can assure you of an utterly seamless Deployment and Transition phase.

By this we mean that issues that may arise during Deployment and Transition will be handled smoothly and efficiently because your people will know exactly what to do.

Here’s how we will prepare your organisation for Deployment:

  • Identify all key players for the Systems Implementation phase and orient them on their specific roles. We’ll make sure they know what possible hitches may come their way and how to deal with them.
  • Identify all end users and their corresponding functions, then assign appropriate access rights.
  • Draw multi-layered contingency plans to capture and address each possible concern that may crop up during Deployment.
  • Prepare a systematic step-by-step procedure and checklist for the entire Deployment stage. Both of them should have been copied from a similar procedure and checklist used in the Acceptance testing phase.
  • Make all stakeholders understand the conditions required before Deployment can commence.
  • Set the appropriate environment so that all stakeholders know what to expect and when to expect them the moment Deployment commences.
  • Prepare Technical Services and Technical Support personnel for the gruelling mission ahead.
  • Make sure all communication processes are well coordinated so that everyone affected will know who to contact and how to get in touch with them when a problem arises.
  • Plan and schedule training sessions so that they can be conducted “just in time”. Training sessions conducted way ahead of Deployment are often useless because the trainees tend to forget about what they learned when the time comes to apply them. Similarly, training sessions conducted way after Deployment also become useless because trainees are seldom able to internalise instructions delivered during crash courses.

Deployment

There are two sets of issues to keep an eye on during Deployment:

  1. Issues directly related to the technology itself, e.g. application functionality and data integrity, and
  2. Issues emanating from the end users, i.e., their unwillingness to use the new system. One reason may be because they find the interface and procedures too confusing. Another would be due to other inconveniences that come with adapting to a new set of procedures.

Despite all the meticulous scrutiny employed during Acceptance testing, there are just some problems that are made obvious only during Deployment. Issues belonging to the first set are dealt with easily because of the plans and procedures we put in place during the Preparation stage. As an added measure, our team will be on hand to make sure contingency plans are executed accordingly.

While the second set of issues is often neglected by many IT consultancy companies, we choose to meet it head on.

We fully understand that end users are most sensitive to the major changes that accompany a new system. It is precisely for this reason why our training activities during Deployment are designed not only to educate them but also to make them fully appreciate the necessity of both the new system and the familiarisation phase they will need to go through.

The faster we can bring your end users to accept the new system, the faster they can refocus on your company’s business objectives.

Here’s what we’ll do to guarantee the smoothest Deployment process you’ve ever experienced.

  • Employ the procedure and checklist formulated during the Preparation stage.
  • Ensure all end users are well acquainted with any additional tasks they would need to perform (e.g. filling up manual logs).
  • Assess which legacy systems can still be used alongside the new technology and which ones have to be retired.
  • Supervise the installation and optimal configuration of all supporting hardware and software to make sure the likelihood of errors originating from them are brought to near-zero levels.
  • Supervise the installation and optimal configuration of the products themselves.
  • Carry out data migration tasks if necessary.
  • Organise and oversee parallel runs to check for data and report inconsistencies.
  • Conduct training sessions in a professional and well-timed manner to eliminate end-users’ feelings of agitation and to take advantage of memory absorption and retention duration as with regards to their assigned duties and responsibilities.

Transition

Do you often feel uneasy whenever the reins to a newly purchased IT system are handed over to you? Perhaps there are some issues that you feel haven’t been fully settled but, at the same time, find it too late to back out, having already invested so much time and resources.

Alright, so maybe the thought of “backing up” never crossed your mind. However, the concern of being “not yet ready” is raised by many organisations towards the tail end of most Deployment stages. This usually drags the Deployment stage into a never-ending process.

Our team of highly experienced specialists will make sure you reach this point with utmost confidence to proceed on your own.

To wrap up our comprehensive IT Systems Implementation offering, we’ll take charge of the following:

  • Verify that all deliverables, including training materials and other technical documentation, are accomplished and expected outcomes are realised.
  • Make sure all technical documentation are placed in a secure and accessible location.
  • Institute best practices to ensure the IT system becomes fully utilised and to reduce its exposure to avoidable risks.
  • Establish open communication lines with the Technical Support team to enable quick resolution of issues.
  • Ensure complete knowledge transfer has been fully achieved so that your people will spend less time calling Technical Support and more on operations contributory to business growth.
What Is Technical Debt? A Complete Guide

You buy the latest iPhone on credit. Turn to fast car loan services to get yourself those wheels you’ve been eyeing for a while. Take out a mortgage to realise your dream of being a homeowner. Regardless of the motive, the common denominator is going into financial debt to achieve something today, and pay it off in future, with interest. The final cost will be higher than the loan value that you took out in the first place. However, debt is not limited to the financial world.

Technical Debt Definition

Technical debt – which is also referred to as code debt, design debt or tech debt – is the result of the development team taking shortcuts in the code to release a product today, which will need to be fixed later on. The quality of the code takes a backseat to issues like market forces, such as when there’s pressure to get a product out there to beat a deadline, front-run the competition, or even calm jittery consumers. Creating perfect code would take time, so the team opts for a compromised version, which they will come back later to resolve. It’s basically using a speedy temporary fix instead of waiting for a more comprehensive solution whose development would be slower.

How rampant is it? 25% of the development time in large software organisations is actually spent dealing with tech debt, according to a multiple case study of 15 organizations. “Large” here means organizations with over 250 employees. It is estimated that global technical debt will cost companies $4 trillion by 2024.

Is there interest on technical debt?

When you take out a mortgage or service a car loan, the longer that it takes to clear it the higher the interest will be. A similar case applies to technical debt. In the rush to release the software, it comes with problems like bugs in the code, incompatibility with some applications that would need it, absent documentation, and other issues that pop up over time. This will affect the usability of the product, slow down operations – and even grind systems to a halt, costing your business. Here’s the catch: just like the financial loan, the longer that one takes before resolving the issues with rushed software, the greater the problems will pile up, and more it will take to rectify and implement changes. This additional rework that will be required in future is the interest on the technical debt.

Reasons For Getting Into Technical Debt

In the financial world, there are good and bad reasons for getting into debt. Taking a loan to boost your business cashflow or buy that piece of land where you will build your home – these are understandable. Buying an expensive umbrella on credit because ‘it will go with your outfit‘ won’t win you an award for prudent financial management. This also applies to technical debt.

There are situations where product delivery takes precedence over having completely clean code, such as for start-ups that need their operations to keep running for the brand to remain relevant, a fintech app that consumers rely on daily, or situations where user feedback is needed for modifications to be made to the software early. On the other hand, incurring technical debt because the design team chooses to focus on other products that are more interesting, thus neglecting the software and only releasing a “just-usable” version will be a bad reason.

Some of the common reasons for technical debt include:

  • Inadequate project definition at the start – Where failing to accurately define product requirements up-front leads to software development that will need to be reworked later
  • Business pressure – Here the business is under pressure to release a product, such as an app or upgrade quickly before the required changes to the code are completed.
  • Lacking a test suite – Without the environment to exhaustively check for bugs and apply fixes before the public release of a product, more resources will be required later to resolve them as they arise.
  • Poor collaboration – From inadequate communication amongst the different product development teams and across the business hierarchy, to junior developers not being mentored properly, these will contribute to technical debt with the products that are released.
  • Lack of documentation – Have you launched code without its supporting documentation? This is a debt that will need to be fulfilled.
  • Parallel development – This is seen when working on different sections of a product in isolation which will, later on, need to be merged into a single source. The greater the extent of modification on an individual branch – especially when it affects its compatibility with the rest of the code, the higher the technical debt.
  • Skipping industrial standards – If you fail to adhere to industry-standard features and technologies when developing the product, there will be technical debt because you will eventually need to rework the product to align with them for it to continue being relevant.
  • Last-minute product changes – Incorporating changes that hadn’t been planned for just before its release will affect the future development of the product due to the checks, documentation and modifications that will be required later on

Types of Technical Debt

There are various types of technical debt, and this will largely depend on how you look at it.

  • Intentional technical debt – which is the debt that is consciously taken on as a strategy in the business operations.
  • Unintentional technical debt – where the debt is non-strategic, usually the consequences of a poor job being done.

This is further expounded in the Technical Debt Quadrant” put forth by Martin Fowler, which attempts to categorise it based on the context and intent:

Final thoughts

Technical debt is common, and not inherently bad. Just like financial debt, it will depend on the purpose that it has been taken up, and plans to clear it. Start-ups battling with pressure to launch their products and get ahead, software companies that have cut-throat competition to deliver fast – development teams usually find themselves having to take on technical debt instead of waiting to launch the products later. In fact, nearly all of the software products in use today have some sort of technical debt.

But no one likes being in debt. Actually, technical staff often find themselves clashing with business executives as they try to emphasise the implications involved when pushing for product launch before the code is completely ready. From a business perspective, it’s all about weighing the trade-offs, when factoring in aspects such as the aspects market situation, competition and consumer needs. So, is technical debt good or bad? It will depend on the context. Look at it this way: just like financial debt, it is not a problem as long as it is manageable. When you exceed your limits and allow the debt to spiral out of control, it can grind your operations to a halt, with the ripple effects cascading through your business.

 

How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.
