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.

Strategy and Portfolio Management

 

A well planned strategy is the necessary bridge between brilliant leadership and excellent execution. Without it, your entire organisation cannot hope to respond quickly and effectively to challenges and changes within the landscape on which it operates.

Strategic planning involves identifying objectives, understanding what resources are needed to attain them, and then allocating the resources to the appropriate units to ensure they are used optimally towards the achievement of desired objectives. Among the end results which can be reflected by your team members are:

  1. Deeper understanding of the competitive environment;
  2. Snappy execution of plans;
  3. Faster, more aligned actions; and
  4. More intelligent and apt responses against strategic moves of the competition.

We understand the need to institute strategic management in such a way that your organisation can easily adapt to unforeseen developments. As such, all our solutions are formulated to make your organisation not only well-guided but also as dynamic as possible.

Strategy Formulation

Before you can proceed to map out any strategy for your company, you’ll have to study your company’s current environment. This will help you determine what courses of action should be taken to be able to navigate through such environment on your way to the end goal.

If you’re not a full time strategist, such a task can either be very daunting or deceivingly easy… the former can prevent your team from getting started, while the latter can lead your team astray.

Ideally, strategy formulation should be carried out as quickly and as efficiently as possible so you can move on to implementation before the competition can react. Our methods can enable your leaders to hit the ground running each time they set out on a strategic plan.

How?

  • We can assist in accurately applying strategic tools like SWOT and Gap analysis, then help integrate the results into an effective strategic plan.
  • We’ll train your team how to carry out effective research techniques so that the information they gather will really be what we need. This is because the tools mentioned earlier can only work effectively if the inputs were picked intelligently. Of course, if you want the entire process expedited, we can also conduct the research ourselves.
  • We’ll establish best practices for top-down, bottom-up, and collaborative strategic management processes. We’ll even show you how to organise and hold meetings where team members are constantly engaged and in-sync, so action plans can be developed and relayed fast.
  • We’ll see to it that strategies for all functional departments (such as IT management, supply-chain, HR, marketing, and legal) are in line with your business strategies, which should in, turn be aligned with your overall corporate strategy.

Strategy Evaluation

Your strategies have to be periodically assessed if you want to determine whether they are attuned to variations affecting your organisation. These changes may include new technologies, emerging competitors, new opportunities, as well as unexpected developments in the economic environment and political climate.

While no time limit is imposed for the build-up of resources vital to the attainment of a specific objective, the window of opportunity can shut on you before you can start amassing such resources. Given this possibility, it is important for your strategies to undergo evaluation processes that will determine whether you should pursue them or not.

Using only the most reliable evaluation techniques, we’ll help you establish whether:

  • Your strategies will place your company in a position that will give it competitive advantage or will erode whatever advantage the competition already has;
  • Your strategies are consistent with the landscape on which your company currently traverses;
  • They are realistic enough in relation to the resources you have on hand;
  • The associated risks have all been identified and the appropriate control measures have already been put in place;
  • The time frames for their full realisation are both realistic and acceptable.

Portfolio Management

In today’s highly competitive market, many of the more successful enterprises are driven by project-based systems.

Now, there’s always a tendency for project managers to become overenthusiastic and to come up with a number of projects that can’t be sustained by available resources. If your project-based company frequently runs out of resources, then either you just have too many projects running or too much is being allocated to a select few.

In both instances, the problem does not necessarily lie on the individual project managers themselves. Rather, what is needed is the ability to have full control over existing projects and investments.

Your leadership should be able to rank projects in terms of their impact to your organisation’s growth, positioning, and profitability. This will give you sufficient information when deciding which projects to pursue, prioritise, or shut down. These are the benefits you’ll gain from our services:

  • A vivid presentation of the big picture. Only when you can step back from all the detail and see the interplay of investments and resources will you be able to make wise decisions regarding how and where to position them.
  • The ability to distinguish between projects with the highest potentials and those that are outdated.
  • Access to expertise that will help you distribute your present IT infrastructure, human resources, financial resources, and facilities across running projects to obtain the biggest benefits for all stakeholders.

Energy efficiency demystified

Energy bills are all about Energy efficiency but energy efficiency management is not all about bills. Energy efficiency means reducing carbon emissions, lowering energy costs and improving the quality of life. Energy efficiency is therefore about conservation of energy in a broader perspective; in fact energy efficiency is almost becoming a moral obligation.

Through adoption of appropriate energy efficiency measures, companies can significantly bring down the overhead costs making hundreds of dollars in savings. Energy efficiency is also synonymous with a better quality of life. Taking appropriate measures to ensure proper insulation protects your premises against extreme weather conditions leading to more productivity and an improvement in the bottom line.

Improved energy efficiency means a smaller amount of carbon emissions, less pollution and a better environment.

It is now easier than ever to visually identify where your facility is wasting energy, how much energy is being wasted while tracking the progress made in reducing energy consumption by turning that detailed, raw energy-consumption data into useful charts and figures.

Having visibility of your Energy usage gives you knowledge of what power you are consuming. This helps you change energy usage behaviours and this can have significant savings and reduction in your electricity bills. Real-time electricity consumption tracking is enough prodding for you to be on the lookout for inefficient energy consumption unit’s e.g.? Heating and cooling equipment, ducts insulation of your premises or a failure of one of these components to perform as intended. Pin-pointing the problem areas is not a walk in the park but fixing it can make your building more energy-efficient and comfortable.

A wide range of solutions are now available for charting and analysing energy consumption that helps energy managers, facilities managers, energy consultants and building-services engineers. These will not only offer advice but will enable you provide tailor made solutions for your organisation by assisting you in developing a sustainable energy strategy. Our energy monitoring software is one example.?

Six Sigma

Six Sigma has received much attention worldwide as a management strategy that is said to have brought about huge improvements and financial gains for such big-name companies as Allied Signal, General Electric (GE) and Motorola.

If you want to give your business the chance to attain the same resounding success, Six Sigma could be the method that will steer you towards that direction.

What is Six Sigma?

So what really is it? Six Sigma is a business management tool that was developed using the most effective quality improvement techniques from the last six decades. Basing its approach on discipline, verifiable data, and statistical calculations, Six Sigma aims to identify the causes of defects and eliminate them, thereby resulting in near-perfect products that meet or exceed customer’s satisfaction.

The core concept behind the Six Sigma method is that if an organisation can quantify the number of “defects” there are in a particular process, improvement activities can be implemented to eliminate them, and get as close to a “zero defects” scenario as possible. Defect here is defined as any process output that fails to meet customer specifications.

Six Sigma is also unique from other programs in that it calls for the creation of a special infrastructure of people within the organisation (“Champions“, “Black Belts“, “Green Belts“) who are to be expert in the methods.

Six Sigma Methodologies

When implementing Six Sigma projects, two methodologies are often employed. Although each method uses five phases each, these two are distinguished from each other using 5-letter acronyms and their specific uses.

DMAIC ? is the project methodology used to improve processes and maximise productivity of current business practices. The 5 letters stand for:

  • D ? Define (the problem)
  • M ? Measure (the main factors of the existing process)
  • A ??Analyse?(the information gathered to deter mine the causes of defects)
  • I ? Improve (the current process based on the analysis)
  • C ? Control (all succeeding processes so as to minimise additional defects)

DMADV – is the method most suitable if your business is looking to create new products or designs. The acronym stands for:

  • D ? Define (product goals as the consumer market demands)
  • M ? Measure (and identify product capabilities and risks)
  • A ??Analyse?(to create the best possible design)
  • D ? Design (the product or process details)
  • V ? Verify (the design)

How does Six Sigma differ from other quality programs?

If you think that Six Sigma is just another one of those business strategies that produce more hype than actual results, think again. Six Sigma uses three key concepts that sets it apart from other business management methods.

  • It is strictly a data-driven approach, where assumptions and guesswork do not figure in the decision making.
  • It focuses on achieving quantifiable financial results ? the bottom line ($) ? as much as giving emphasis on customer satisfaction.
  • It requires strong management leadership, while at the same time creating a role for every individual in the organisation.

Is Six Sigma right for your business?

While many other organisations such as Sony, Nokia, American Express, Xerox, Boeing, Kodak, Sun Micro-systems and many other blue chip companies have followed suit in adopting Six Sigma, the truth is, any company — whether you have a large manufacturing corporation, or a small business specialising in customer service.

Certainly, there is a lot more to Six Sigma than what you can probably absorb in one sitting or reading.

With our wide range of business management consultancy services, we can help you understand the Six Sigma method in the context of your business. We can also help you establish your improvement goals, set up your program, and train your own team of “champions” who can lead in implementing your Six Sigma goals.
