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.

Maturing Into CMMI

 

In all likelihood, the reason why you landed on this page was because you were seeking CMMI experts to help you meet the demands of a growing number of potential clients who require CMMI compliance.

Whether or not you’re here for that reason, you might want to know why CMMI or Capability Maturity Model Integration is steadily becoming a common denominator among highly successful software and engineering development companies. If you stay for a while, we can show you how CMMI can substantially increase your organisation’s chances of:

  • reducing development costs;
  • acquiring new customers and retaining old ones;
  • beating deadlines;
  • bringing down development time;
  • increasing the overall quality of your products and services; and
  • improving the level of satisfaction of customers, employees, and all other stakeholders.

Surely, no organisation can be too small or too big to aspire for such benefits of attaining high levels of maturity and capability.

If you want to look beyond Maturity Level ratings, then you’ve come to the right place. We focus on introducing CMMI principles and blending them into your organisation’s culture to achieve a truly superior and sustainable business advantage. Compliance will then be an inevitable offshoot of the actions you make.

Likewise, if you simply want to obtain a deeper understanding of CMMI and learn how it can be applied either to your entire organisation or to specific projects, we’d be happy to assist you in that regard as well.

Finally, when you’re ready, we can also conduct CMMI appraisals either for benchmarking purposes or simply for determining how well your process improvement initiatives are going.

CMMI Consulting

Are you worried that implementing CMMI might entail an overhaul of your current processes? Don’t be.

CMMI is all about improving current processes, not replacing them. Ideally, the final result of all process improvement activities should be hinged on your own business objectives and context, so we’ll make sure it remains that way when we work with you.

We rely on our extensive knowledge and experience in CMMI, engineering, software development, and technologies as well as in change and project management in providing model-based process improvement services. Whether you’re gearing up for an appraisal or simply want to employ CMMI-based practices, these are the things we can do for you.

  • Help you interpret how CMMI can be implemented in relation to your business.
  • Assist in convincing sponsors and stakeholders to support your CMMI implementation initiatives.
  • Introduce the necessary training to all individuals who need to undertake them.
  • Conduct a Gap Analysis to find out where your company’s current processes stand relative to their CMMI specifications.
  • Assemble a process group that will champion your process improvement 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.
  • Introduce tools and practices that will improve the efficiency of our process improvement initiatives.
  • Carry out periodic evaluations and produce reports to provide sponsors and stakeholders a clear picture of our progress.

CMMI Training

Still not convinced CMMI is right for you? There’s only one way to fully grasp the benefits of implementing CMMI – take the Introduction to CMMI course. Although what happens next is entirely up to you, we’re pretty sure you’ll make the right decision after passing it.

Do you need to include people from your organisation in a SCAMPI (Standard CMMI Appraisal Method for Process Improvement) team? They’ll have to undergo this course too. The Introduction to CMMI is for systems and software engineering managers and practitioners, appraisal team members, process group members, and basically anyone who want to grasp CMMI fundamentals.

This is what you’ll be able to do after going through 3 days of lectures and exercises:

  • Gain a deeper understanding of the various components of CMMI-DEV models and their relationships.
  • Discuss the process areas in CMMI-DEV models.
  • Extract and interpret aspects in the model relevant to your own organisation’s processes.

We also offer highly specialised training and workshops such as those for:

  • Achieving High Maturity Levels
  • Top Executives
  • Team Building in Preparation for Appraisals

CMMI Appraisal

An organisation new to CMMI will want to know first how far their current processes are relative to the implementation of model-based improvements in order to determine the resources and time that have to be spent to get there.

Similarly, an organisation already well acquainted with CMMI and has begun taking steps in improving processes, will eventually want to know how close it has come to the Maturity Level it has aimed for.

In both cases, these organisations will have to be assessed by a qualified CMMI appraiser to obtain an accurate picture of their current status. We can perform appraisals on either your entire organisation or on specific projects/practices within a process area. Our appraisers can conduct the following SCAMPI (Standard CMMI Appraisal Method for Process Improvement) appraisals:

  • SCAMPI Class A – This is what you’ll need if you’re aiming for a level rating.
  • SCAMPI Class B – You may want to use this for process reviews or for preparing for a SCAMPI Class A.
  • SCAMPI Class C or Gap Analysis – We typically conduct this for organisations who have yet to implement CMMI-based initiatives so that they can design the most cost-effective road map for the implementation proper.
How Energy Conservation saved Fambeau River Paper

Rising energy costs caught this Wisconsin paper mill napping, and it soon shut down because it was unable to innovate. Someone else bought it and turned it around by measuring, modifying, monitoring and listening to people.

The Fambeau River Paper Mill in Prince County, Wisconsin USA employed 13% of the city?s residents until rising energy costs shut it down in 2006. Critics wrote it off as an energy dinosaur unable to adapt. But that was before another company bought it out and resuscitated it as a fleet-footed winner.

Its collapse was a long time coming and almost inevitable. Wisconsin electricity prices had grown a third since 1997, the machinery was antiquated and the dependence on fossil power absolute. So what did the new owners change, and is there anything we can learn from this?

The key to understanding what suddenly went right was the new owners? ability to listen. They requested a government Energy Assessment that suggested a number of small step changes that took them where they needed to go in terms of energy saving. These included enhancements in steam systems and fuel switch modifications. However they needed more than that.

The second game changer was tracking down key members of the old workforce and listening to them too. This combination enabled them to finally hire back 92% of the original labour force under the same terms and conditions – and still make a profit (the other 8% had moved on elsewhere or retired). The combined energy savings produced a payback plan of 5.25 years. Three years into the project their capital investment of $15 million had already clawed back the following electricity savings.

  • Evaporator Temperature Control $2,245,000
  • Hot Water Heat Recovery $2,105,000
  • Paper Machine Devronisers $1,400,000
  • Increased Boiler Output $1,134,000
  • Paper Machine Modifications; $761,000
  • Motive Air Dryer $610,000
  • Accumulator Savings $448,000
  • Densified Fuels Plant $356,000

In terms of carbon dioxide produced, the Fambeau River Paper Mill?s contribution dropped from 1 ton to 600 pounds.

How well do you know where your company?s energy spend is concentrated, and how this compares with your industry average; could you be doing better if you innovated, and by how much? Get these questions answered by asking ecoVaro how easy it could be to get on top of your carbon metrics. This could cost you a phone call and a payback on it so rapid it’s not worth stopping to calculate.

What ISO 14001 Status did for Cummins Inc.

Cummins manufactures engines and power generation products, and has been a household name almost since inception in 1919. It sells its products in over 300 countries, through approximately 6,000 dealerships employing 40,000 people. Because its product line runs off fossil fuel it is under steady pressure to display a cleaner carbon footprint.

Cummins decided to go for the big one by qualifying for ISO 14001 certification. This is a subset of a family of standards relating to managing environmental impact while complying with all applicable legislation. In this sense, it is similar to the ISO 9000 quality management system, because it focuses on how products are produced (as opposed to how those products perform). Compliance with ISO 14001 was a doubly important goal, because it is part of the European Union?s Eco Management and Audit Scheme and fast becoming mandatory on suppliers to governments.

The qualification process follows the well-established principle of plan, do, check, act. It begins with gap analysis to detect materials and processes that affect the environment. This is followed by implementation of necessary changes affecting operations, documentation, emergency strategies and employee education. The third step involves measuring and monitoring performance. Finally, the project moves into a phase of ongoing maintenance, and continuous improvement as circumstances change.

In Cummins case, the project was almost worldwide and called for environmental, health and safety reporting throughout the organisation. The information was shared via a globally accessible document repository, and then processed centrally at the head office in Columbia, Indiana USA.

Measuring environmental performance almost inevitably has other benefits that make it doubly worthwhile. Speaking at the 2014 National Safety Council Congress after receiving the top award for excellence, Cummins chairman and ceo Tom Linebarger commented on a journey that was ?nothing short of amazing? yet wasn’t even a ?pathway to the finish line?.

?All of us feel like we have way more to do to make sure that our environment is as safe as it could be,? he added, ?so that our sustainability footprint is as good as it can be and that we continue to set more aggressive goals every year. That’s just how we think about it.? Linebarger concluded.

If you are taking your company on a journey to new heights of environmental excellence, then you should consider choosing ecoVaro as your travelling companion. We are environmental management specialists and have proprietary software geared to process your data. We also have a wealth of experience, and a treasure chest of roadmaps to help you achieve your goal.
