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 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.

 

Data Leakage Prevention – Protecting Sensitive Information

When DuPont lost $400 million in intellectual property, it wasn’t because a hacker from the other side of the world infiltrated their system. The information was simply stolen by a former employee. Alarmingly, data loss incidents are not always caused by deliberate actions.

A file containing personal information accidentally attached to an email and sent to multiple recipients; financial data stored in a USB pen drive, accidentally left in a restaurant; or bank account data of colleagues, inadvertently posted on a company website – these are also some of the everyday causes of data loss.

A report done by research company Infowatch regarding global data leaks in 2010 showed that there were actually more accidental data leaks in that year compared to intentional ones. Accidental leaks comprised 53%, while intentional leaks comprised 42% (the rest were unidentified).

But even if they ?only? happened accidentally, breach incidents like these can still be very costly. The tens of thousands of dollars that you could sometimes end up paying in civil penalties (as in the case when you lose other people?s personal information) can just be the beginning. More costly than this is the loss of customer and investor confidence. Once you lose those, you could consequently lose a considerable portion of your business.

Confidential information that may already be leaking out right under your nose

With all the data you collect, process, exchange, and store electronically every day, your IT system has surely now become a storehouse of sensitive information. Some of them, you may be even taking for granted.

But imagine what would happen if any of the following trade secrets fell into the wrong hands: marketing plans, confidential customer information, pricing data, product development strategies, business plans, supplier information, source codes, and employee salaries.

These are not the only kind of data that you should be worried about. You could also get into trouble if your sloppy IT security fails to protect employee or client personal information such as their names; social security numbers; drivers license numbers; or bank account numbers and credit/debit card numbers along with their corresponding PINs.

In some countries, you could face onerous data breach notification requirements and heavy fines when these kind of data are involved.

There are now more holes to plug

It’s not just the different varieties of sensitive electronic information that you have to worry about. Because these data can take on different forms, i.e. data-at-rest, data-in-motion, and data-at-the-endpoints, you also need to take aim at different areas in your IT system.

Sensitive information can be found ?at rest? in each of your employees? hard disks, in your servers, storage disks, and in off-site backup disks. They can also be found ?in motion? in email, instant messaging, social networking messaging, P2P file sharing, ftp, http, and so on.

That’s not all. Your highly mobile workforce may have already introduced yet another high-risk area into your system: data-at-the-endpoints. This includes USB flash-disks, laptops, portable hard disks, CDs, and even smartphones.

The main challenge of data leak prevention

Having been made aware of the various aspects of data leakage, have you already come to grips with the extent of the task at hand?

There are two major things you need to do here to prevent data leakage.

One, you need to identify what data you have that can be considered as sensitive/confidential information. Of course you have financial information and employee salaries in your files. But do you also store personally identifiable information? Do you have trade secrets that are stored in electronic form?

Two, you need to pinpoint their locations. Are they only on your hard disks and laptops? Or have they made their way to flash drives, CDs/DVDs, or portable HDDs? Are they being transmitted through email or any other file transfer media?

The reason why you need to know what your sensitive data are as well as where they are is because you would like all efforts of securing them to be as efficient and unobtrusive as possible.

Let’s say, as a way of protecting your data, you decide to implement encryption. Since encryption can consume a lot of storage space and significantly reduce performance, it may be impractical to encrypt your entire database or all your files. For the same reason, you wouldn’t want to encrypt every single email that you send.

Thus, the best way would be to encrypt only the data that really need encryption. But again, you need to know what data needs to be encrypted and where those data can be found. That alone is no simple task.

Not only will you need to deal with the data you already have, you will also have to worry about the data that will go through your systems during the course of your day-to-day transactions.

Identifying sensitive data as it enters or leaves your system, goes through your network, or gets stored in your file system or database, and then applying the necessary security actions should be done automatically and intelligently. Otherwise, you could end up spending on a lot of man-hours or, worse, wasting them on a lot of false positives and negatives.

Implementing Large-Scale Complex Business Change

Sometimes, driving your people to work harder is not enough for your organisation to withstand the pressures laying siege to it. With uncertain economic conditions, unpredictable fresh competition, and looming threats from the environment or even pandemic-grade diseases, empowering your people to not only ‘think’ but also to ‘step’ out of the box is currently the name of the game.

However, such initiatives typically require sweeping changes throughout your entire organisation … and to think even the slightest change is often met with hard resistance.

Whether you’re about to undergo an M&A, relocate due to a major catastrophe, scale down to a skeletal workforce, or implement a brand-new company-wide strategy, our systematic approach to large-scale complex business change can help you make the transition as seamless as possible.

We understand the importance of the human aspect in change management. That is why we’ll focus on making your people appreciate the benefits of having to learn new skills, perform new tasks, employ modern technologies, and go through new processes in order to tone down the resistance level.

Our entire process spans from top to bottom, wherein we’ll start with your sponsors, down to your managers, and then to other stakeholders in making them appreciative of the needed changes and in order to achieve alignment with your organisation’s goals. Our top to bottom approach is also aimed at casting a positive “shadow of the leader” on people down the line, enabling them with an optimistic view despite the gruelling tasks before them.

We invite you to have a look at the steps we take in implementing large-scale complex business change to win over a strong and lasting commitment to it.

Evaluating the Required Change

Large-scale complex business change initiatives can be implemented expeditiously and economically if you’ve clearly defined the scope of the change as well as the forces that shape your organisation. You’ll want to know which areas yield easily and which are hard to change to determine where and how you’re going to focus more of your efforts on.

To arrive at a sound and systematic plan, we first gather as much information as needed and analyse them. We determine whether your departments have the required capabilities and how we can arrive at a clear organisational alignment. That way, we don’t waste time, effort and resources when the moment comes to carry out the plan.

These are some of the diagnostic procedures we perform in evaluating the required change.

  • Change complexity analysis. We’ll assess the contribution of people and task factors to the overall complexity of the change project. This will help us determine how to approach the problem efficiently.
  • Causal analysis. By establishing cause and effect relationships, we can identify root or circular causes. This will allow us to pinpoint problem areas and prevent a repetition of past mistakes.
  • Structural analysis. Any company is propped up by a number of structures: organisational, process, motivational, social, and physical, among others. Understanding the structures that drive, motivate, hamper, connect, and influence your people’s behaviours can provide insights as to how or where structural change can best be executed.
  • Context analysis. We’ll look into market forces as well as political, economic, social, technological, legal, and environmental factors enveloping your business. We’ll also analyse your driving objectives, organisational alignment, and organizational capabilities. By analysing the internal and external environment in which your business currently operates, we can formulate a customised strategic and effective plan of action.

Managing Stakeholders

Change initiatives won’t prosper without total commitment from all stakeholders. Stakeholders refer to people in your organisation who either have interests in the change project or can be affected by it.

We deal with your stakeholders starting from the top because if we can’t gain full commitment from those already in the best position to spur the diverse entities in your company into active cooperation, striving to secure commitment from other areas will be futile.

That is, if you don’t have the full support of your key and principal sponsors, i.e. the people who have the biggest say and have greatest control over resources in your organisation, you can’t hope to sustain the change endeavour, let alone provide the much needed spark to get it started.

Here’s how we carry out our stakeholder management actions.

  • Conduct research to identify all stakeholders: the sponsors, your internal and external partners, the main targets of the change, and all interested parties. That way you can “switch on” implementors of each change action in the proper sequence.
  • Not everyone will offer resistance to your change endeavours. We’ll help you identify those stakeholders and sponsors who are willing to offer support, evaluate the level of support they are willing to give, harness all available supports and utilise them extensively to benefit the change.
  • Gain a deeper understanding as to why certain stakeholders are willing to lend support. In doing so, we can implement the right strategies that will encourage them to continue supporting you.
  • Assemble a leadership team that will champion your change initiatives. We’ll facilitate effective collaboration among its team members, transforming them into a cohesive force designed to carry out plans and motivate everyone else down the line.
  • Upon realisation of the change project, we’ll see to it that all stakeholders get a taste of the carrot at the end of the stick. This will encourage them to continue active cooperation in future change initiatives.

Planning for the Change

Anyone who has experienced having their car stuck in the mud knows that stepping on the accelerator will only get the vehicle trapped even deeper. Without the aid of a towing truck, getting the car out will require careful planning since different combinations of pulling, pushing, lifting, rocking to-and-fro, and stepping on the accelerator may be needed.

Of course, some combinations are just better than others. The same principle holds when effecting change.

Our approach to change management typically varies depending upon the information we obtain from the different analyses performed earlier. For instance, since not all organisations are suitable for a collaborative approach, we will employ either collaborative, consultative, directive, or coercive change management strategies wherever applicable.

A well-planned change will result in a smoother, less costly, and less disruptive transition. Here’s how we’ll help you plan your change initiatives.

  • When put in a predicament similar to the car-in-the-mud, the basic strategy entails identifying the current resisting forces and predicting what other resisting forces may be encountered along the way. After researching and pointing out your organisation’s resistance forces, we’ll lay out the most appropriate facilitation, education, and negotiation techniques.
  • To bring down wastage to the lowest possible levels, we’ll engineer a change delivery plan that involves the most cost-effective sequence of driver, process, technology, organisational, and people alignment.
  • To win and maintain a high level of trust, confidence and commitment from all sponsors and stakeholders, we’ll present a clear road map of the change process as well as landmarks that will prove how far we will have gone. These landmarks will then be brought to each sponsor’s and stakeholder’s attention each time they are arrived at in order to build up assurance and continued commitment.
  • We’ll design measurement tools and schedule reporting deadlines so that you’ll know what to look forward to and when to expect them.

Managing the Change

Your company will hold a better chance of maintaining a sizeable lead over the rest of the pack if you constantly establish a rally point and instil in your stakeholders the drive to rally to that point from the get-go. To make this happen, your company must undertake the unfreezing, transition, and refreezing phases of change skilfully in order to bring all stakeholders into the right mindset.

Our specialists’ systematic and efficient methods for each of these phases are designed to simplify the management of each phase as well as provide a seamless shift from one phase to the next. This is what we’ll do:

  • Set up a change project management office to ensure that everything associated with the change initiative is given the needed attention and resources even while all the other usual processes in your organisation run concurrently.
  • To unfreeze your people and get them started on the road of change, we’ll employ unfreezing techniques wherever they are most appropriate. We’ll resort to different kinds of methods ranging from presenting persuasive evidence justifying the need for change to showing a motivational vision for inspiring your people to embark on the change process.
  • Since it is during the transition phase when your people can find themselves groping in the dark, we’ll offer executive coaches for your senior managers; facilitators to provide guidance during team meetings and other change activities; coaches to educate and inspire them to meet the change with the right attitude; trainers to teach new systems, procedures, and technologies; as well as employ a variety of other techniques in order to make the transition phase as seamless as possible.
  • Although your people should always be ready to undertake the next major change after a previous one, there should be points in between where they can taste the spirit of success, establish a temporary base to rejuvenate, and immediately gain a deeper understanding of the nearby terrain so as to envision the next rally point. We’ll see to it that this vital phase of change is carried out completely.
