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.

Technology and process improvement

Tightening organisational flow to improve productivity and minimise costs is a growing concern for many businesses post the Global Financial Crisis. Businesses can no longer afford to waste time and personnel on inefficient processes. Organisations using either Six Sigma or Lean techniques better manage their existing resources to maximise product out-put. Both of these techniques involve considerable evaluation of current processes.

What is Six Sigma?

Six Sigma is an organisational management strategy that evaluates processes for variation. In the Six Sigma model, variation equates waste. Eliminating variation for customer fulfilment allows a business to better serve the end-user. In this thought model, the only way to streamline processes is to use statistical data. Each part of a process must be carefully recorded and analysed for variation and potential improvements. The heart of the strategy embodied by Six Sigma is mathematical. Every process is subject to mathematical analysis and this allows for the most effective problem solving.

What is a Lean Model?

Lean businesses do not rely on mathematical models for improvement. Instead, the focus is on reducing steps in the customer delivery cycle, which do not add value to the final deliverable. For example, maintaining excess inventory or dealing with shortages would both be examples of waste behaviour. Businesses that operate using Lean strategies have strong cash flow cycles. One of the best and most famous examples of Lean in action is the Toyota Production System (TPS). In this system, not only is inventory minimised, but physical movement for employees also remains sharply controlled. Employees are able to reach everything needed to accomplish their tasks, without leaving the immediate area. By reducing the amount of movement needed to work, companies also remove wasted employee time.

Industry Applications for Lean and Six Sigma

Lean businesses reduce the number of steps between order and delivery. The less inventory on hand, the less it costs a business to operate. In industries where it is possible to create to order, Lean thinking offers significant advantages. Lean is best utilised in mature businesses. New companies, operating on a youthful model, may not be able to identify wasteful processes. Six Sigma has shown its value across industries through several evolution’s. Its focus on quality of process makes it a good choice for even brand new businesses. The best use is the combination of the two strategies. With the Lean focus on speed and the Six Sigma focus on quality combined, the two organisational processes create synergy. By itself, Lean does not help create stable, repeating success. Six Sigma does not help increase speed and reduce non value-added behaviours. Combined, these two strategies offer incredible value to every business in cost savings.

Using Technology to Implement Lean Six Sigma

Automation processes represent an opportunity for businesses to implement a combination of both Lean and Six Sigma strategies. Any technology that replaces the need for direct human oversight reduces costs and increases productivity. A few examples of potentially cost saving IT solutions include document scanning, the Internet, and automated workflow systems.

  • Document Scanning – Reducing dependency on paper copies follows both Lean and Six Sigma strategies. It is a Lean addition in that it allows employees to access documents instantly from any physical location. It is Six Sigma compliant in that it allows a reduction on process variation, since there is no bottleneck on the flow of information.
  • The Internet – The automation potential offered by the Internet is limitless. Now, businesses can enter orders, manage logistics and perform customer service activities from anywhere, through a hosted portal. With instant access to corporate processes from anywhere, businesses can manage workflow globally, allowing them to realise cost savings from decentralisation.
  • Automated Work Systems – One of the identified areas of waste in any business is processing time. The faster orders are processed and delivered, the greater the profits for the company and the less the expense per order. When orders sit waiting for attention, they represent lost productivity and waste. Automated work systems monitor workflow and alert users when an item sits longer than normal. These systems can also reroute work to an available employee when the original worker is tied up.

Each of these IT solutions provides a method for businesses to either reduce the number of steps in a process or improve the quality of the process for improved customer service.

Identifying Areas for Lean Six Sigma Implementation

Knowing that improved processes result in improved profits, identifying areas for improvement is the next step. There are several techniques for creating tighter processes with less waste and higher quality. Value Stream Mapping helps business owners and managers identify areas of waste by providing a visual representation of the total process stream. Instead of improving single areas for minimal increases in productivity, VSM shows the entire business structure and flow, allowing management to target each area of slow down for maximum improvement in all areas.

Seeing the areas of waste helps management better determine how processes should work to best obtain the desired outcomes. Adding in automated processes helps with improved process management, when put in place with a complete understanding of current systems and their weaknesses. Start with mapping and gain a bird’s-eye view of the situation, in order to make the changes needed for improvement.

How FieldElite helps Electricians

The need to hire an electrician arises more often than we expect. It’s quite common to come across problems with structure-wiring, whether at home or in your business premises. It’s, therefore, not surprising to come across a home or a business owner in search of electrical services.

Whether a startup or a fully-fledged business that offers electrical services, there are challenges that come with running the venture. Where you have field service electricians, the challenges are even compounded, more so on matters of assigning tasks, receiving complaints from customers, and receiving field service reports.

As we all know, an electrical business isn’t just limited to the management of field service electricians. You’ll have to manage all the processes, a responsibility that can be quite daunting.

It doesn’t have to be difficult, though. You can take advantage of a field service management software program to make the entire management process effortless.

FieldElite is one such software. With FieldElite, you can assign tasks, communicate, and receive reports from your electricians on the go. Incorporating field service management in your electrical business enables you to run your business operations smoothly. 

Below are some of the benefits of using FieldElite field service management software. 

Increased Efficiency

Improved efficiency is the number one benefit electricians can get from field service management software. With FieldElite, electricians can accept jobs while in the field and add attachments together with client signatures using their smartphones or tablets. From the field management software, they can get information on the optimal route to the site, the tools required for the job, the service history of the customer, and contractual commitments.

Managing and scheduling tasks on FieldElite are just a few clicks away for office-based operators. That means reduced travel times and delays that often cripple workforce management.

Improved Professionalism

FieldElite field management software gives you a professional edge over your competitors. With this field management software, you can store all your business-related information in a central place. Therefore, each of your electricians can access the data from anywhere using their smartphone or tablet installed with the FieldElite mobile application. As such, there?s no breach in communication, and that means the electricians will get the scheduled tasks on time. Building such relationships with your team in the field encourages teamwork and motivates each team member to play their part. Again, since you can monitor what’s going on in the field, you can address the issues raised by your electricians or customers as soon as possible. 

Effective Communication

Timely communication is very essential if you’re working with field technicians. Since you’ll not always be with them in the field, it’s always important to establish a proper communication channel to ensure information reaches them in time. With FieldElite field service management software, electricians receive notifications and details about tasks assigned to them via the FieldElite mobile app.

On the other hand, office-based staff can access the report with the details of the job once the electrician completes the given task. This implies that both the electricians and the office-based operators can get communication instantly, enabling them to see and manage their workloads. Individual electricians can close jobs on-site and proceed to the next task without having to do paperwork reporting. For this reason, electricians can complete multiple tasks within a short time, which improves their overall productivity.

High Accuracy

With FieldElite field service management software, missing data or incomplete information is a thing of the past. Electricians no longer have to deal with paperwork, which can be daunting and time-consuming, yet with a million and one errors. With FieldElite advanced mobile features, all field service processes and operations are automated. The electricians are left with quite little to do, and that minimises data entry errors.

Because the managers get real-time updates from the field techs, they can accurately maintain and track the field processes. With FieldElite mobile features, managers can get information regarding the job status, the actual time of arrival, and the time taken to complete the task. With such updates, the electricians are better placed to do the job well without wasting much time, thus improving their overall productivity. 

Improved Co-ordination With The Team 

Apart from improving the productivity of the electricians, FieldElite improves coordination with the entire management team. For instance, an electrician can be assigned new tasks within the same area where they’re currently assigned instead of sending another to complete a task in that same place. FieldElite makes this possible by always capturing the current location and job status.

Whenever a new request is made in an area, FieldElite first checks the database to confirm if there is an electrician already assigned in that area. If the status of the ongoing assignment is complete or almost complete and the new task request can wait for the remaining time, the electrician in the field would be assigned the new task. By doing so, the business saves on cost and time and minimises movements. 

Improved Customer Satisfaction

As an electrician, you’ll only be satisfied if the service you offer makes the customer happy. Apart from fixing their wiring problems, they?d be happy if you responded quickly to their request. This is only made possible with field service management software. With FieldElite, managers can notify the electricians on the service requests in their respective areas, allowing them to respond to the call within a very short time. Not only does this give you some level of satisfaction as the business owner but it’s also a win for the company. 

Make your field work-flow better with FieldElite, and improve the productivity of your electricians. With FieldElite releasing regular and timely updates, users aren’t left behind whenever there are changes in the field service industry. The updates introduce new features and capture new standards to ensure that you get the best experience with the software at all times.

How Bombardier Inc. scored a Bulls Eye

When travelling anywhere in the world on land, sea or air, chances are, you will travel courtesy of something made by aerospace and transportation company Bombardier based in Montreal, Canada. In 2009, it set itself the goal of carbon neutrality by 2020. In other words, it hoped to remove as much carbon dioxide from the atmosphere as it was putting in.

By 2012, Bombardier concluded it was not going to become carbon neutral by 2020 at its current rate of progress. It discounted purchasing carbon offsets because it believed it would serve its interests better by introducing new energy-saving products to market faster. That way, it would achieve its objectives vicariously through the decisions of its customers. But that was not all that forward-thinking Bombardier did. It also set itself the following inward-facing objectives:

  • Reduce carbon footprint through efficient use of energy and less emissions
  • Involve the Bombardier workforce to raise awareness of behaving responsibly
  • Implement sustainable initiatives to further reduce the company carbon footprint

Specific Examples

At its Wichita site, Bombardier (a) fitted a white roof and insulation reducing summer energy consumption by 40%, (b) added an energy recovery wheel to balance air circulation, and (c) introduced skylights with integrated controllers to lower energy consumption by lighting.

At Mirabel, it enhanced the flue-gas management system by adding a pressure differential damper.

At Belfast, Bombardier (a) optimised HVAC systems to reduce pressure on chilling and air-handling plants, (b) installed solar panels on the roof, and (c) obtained approval for a waste-to-energy plant that will convert 120,000 tonnes of non-recyclable waste material annually.

By the end of 2013, Bombardier had already beaten its immediate targets by:

  • Reducing energy consumption by 11% against 2009
  • Reducing greenhouse gas emission by 23% against 2009
  • Reducing water consumption by 6% against 2012

Future Plans

Bombardier will never stop striving to reach its goal of carbon neutrality by 2020. It has a number of other projects in the pipeline waiting for scarce resources to fund them. During 2014, it continued with energy efficient upgrades at its French, Hungarian, Polish, Swiss, and UK plants.

These include consumption monitoring systems, LEDs for workshop lighting, new heating systems, and outdoor energy-saving tower lighting. The monitoring is important because it helps Bombardier focus effort, and provides measured proof of progress.
