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.

How an EMS Can Cut Your Carbon Emissions

Your business carbon footprint is directly tied to the efficiency of its energy consumption. From the equipment used in industries, lighting and air conditioning in offices, shopping malls and other commercial buildings, the load used by everyday machines like the coffee makers in the employee breakroom, to hot water boilers in apartment complexes, how much do your processes affect the environment? Standards like the ISO 14001:2015 are being implemented to enable businesses to reduce their impact on the environment, from optimising their energy usage, minimising waste, turning to renewable power sources, all through to preventing pollution and complying with their specific regulatory requirements. How do you handle the volume of data that needs to be obtained and assessed?

Energy management systems come in to enable you to analyse your consumption, identify factors affecting your total energy use – from temperature and humidity conditions, to equipment that is causing spikes, and observe your usage patterns. That way, you can put in measures to minimise wastage while increasing your operational efficiency, reduce your carbon emissions and track your progress all the way. Here, we’ll break down how this is achieved.

Going Green With An Energy Management System

This is a holistic approach aimed at minimising wastage and optimising energy usage. It includes:

Auditing your energy consumption

The first step is really quantifying how much energy you use, which systems are causing unnecessary load, all through to where there are inefficiencies in the facility. Which equipment has the largest impact on your bill? An energy management system allows you to view it all from one dashboard, such as with the ecoVaro EMS that takes you down to the sub-meter level.

Here, you get real-time data that is collected by the ecoVaro loggers – from electricity use, gas, water, temperature, solar power, humidity, air pressure – the readings can all be monitored. This is done 24/7, and the consumption feeds are recorded. Moreover, ecoVaro pulse data is collected every 15 minutes – which is particularly important when it comes to analysing trends over a time period, be it daily, weekly or monthly.

Data is only useful if it can be properly analysed, right? So instead of just bombarding you with spreadsheets of numbers, the EMS displays the records into graphs and charts that are easy to comprehend – all from the same interactive interface. So, whether you’re the energy manager in the facility, or you want reports that can be shared with the CFO, owners of the business, or even staff themselves to enable them to understand the energy saving policies that you will put in place – you will be able to carry this out.

ecoVaro gives you different ways to analyse the data from the readings that have been recommended. For instance, the heat mapping from the interface allows you to see the building’s energy use during different periods at a glance. The site-by-site analysis in particular enables the building or energy manager to assess each individual premises, from checking which block in the school is causing the energy bills to surge, the facility whose performance is falling behind, all through to the office building with the highest carbon footprint. In fact, the carbon and sustainability reports from ecoVaro EMS enables you to see the impact that your operations have. You even get to compare tariffs from the different energy suppliers, that way you can go with the option that is most suited to your situation.

Setting a baseline for your operations

This is essentially a “before/after checkpoint” that you will use to compare the effectiveness of subsequent measures that you will undertake. After making modifications to the systems in your business, you will want a clear picture of whether the new measures are actually benefiting your operations and optimising your energy efficiency, or whether they are deteriorating the performance further. The energy baseline will be critical in analysing your progress.

Reports like the CUSUM (cumulative sum) charts on ecoVaro show you the energy performance, be it of a boiler in a factory, office building, or chain of hotels – over a set period of time. You can then compare this to the baseline, which will show you if the changes you will implement will make you savings. The heatmaps also come in handy here, showing you the energy consumption at each meter, whether it is low, medium or high compared to the baseline that has been set. The heatmaps give a quick visual to analyse resource usage.

Creating energy targets

After understanding your energy consumption and seeing how it impacts your business, next is mapping out short- and long-term goals that you want to attain to optimise your usage and reduce your carbon footprint.

For instance, short-term targets can include the likes of decreasing the night-time lighting load, and adjusting HVAC uptime depending on the level of activity in your business premises for the different hours of the day.

For the long-term targets, these include setting a specific percentage average kWh reduction for the different industrial sites or buildings under your management; lowering the demand kW throughout the building by a specific range year-on-year; as well as the percentage with which you want the carbon emissions decreased annually.

Cost efficiency also factors in. For instance, entering your current tariffs into the conversion factoring dashboard on ecoVaro will show you how your consumption translates to the bills that you receive – and even shows you what you stand to save by negotiating for new energy contracts with your utility firm.

Identifying initiatives and implementing energy saving programs

These are geared towards improving your energy efficiency and reducing your carbon footprint. They vary from one industry to the next. For instance, these can include:

Getting motion/occupancy detectors and automatic dimmers installed in the facility

These are lighting controls that enable you to save money and energy by automatically turning the lights off when they are not required (people have left the room), and reducing the light levels for those cases where full-on brightness is not needed. For instance, the dimmer controls enable variable indoor lighting, reducing the wattage and output when dimming the lightbulbs, saving energy in the process. These can be manual, or operated with sensors or timers.

Motion sensors on the other hand will automatically turn on the lights after they detect motion, then after a short while turn them off – they are typically used for utility and outdoor security lighting. There are also occupancy sensors used in rooms, which turn on the lights when they detect indoor activity, then turn them off or reduce the light output when the particular space is unoccupied.

Switching to energy-efficient light fixtures such as CFL or LED bulbs

Lighting costs are a major contributor to the energy bills being footed by the business. What kind of systems do you have set up?

Incandescent bulbs are rapidly being phased out due to their inefficiencies. They work by a wire tungsten filament getting heated until it glows – a process that sees almost 90% of its energy being released as heat, instead of light. In addition, with an average lifespan of just 1,500 hours, there is the need for better alternatives – and they have already been around for over a decade: CFL and LED bulbs, which save on energy and have far less carbon emissions.

Compact fluorescent light bulbs (CFLs) light up when an electric current going through a tube with argon and trace mercury gases generates ultraviolet light, stimulating the fluorescent coating that’s on the inside of the tube, which in turn produces light. As such, a 15-watt CFL will have about the same light output as a 60-watt incandescent bulb. This makes them approximately 4 times more efficient compared to the incandescent bulbs, with a lifespan of 10,000-15,000 hours. This translates into fewer replacements and greater energy savings. However, there are still concerns about the mercury that is in the CFLs, though it is still in small quantities – basically smaller than the tip of your pencil. In addition, the CFLS aren’t; dimmable. They are usually used as a replacement for incandescent bulbs before completely switching to the more efficient LEDs.

Light-emitting diode bulbs (LEDs) Take things a notch higher. Here, electrons moving through a semiconductor emit the light, and you can get the LEDs for visible light, ultra-violet, and infrared spectrums. Here, the lifespan is 25,000–35,000 hours, which is more than double that of CFLs, and leagues beyond the standard incandescent bulb. Moreover, with a 16.5W LED bulb you’ll be getting the same lighting as a 20W CFL, or a 75W incandescent bulb.

You will notice that when you touch LEDs, they feel cool, and this is because less energy is getting converted into heat. With the energy efficient bulbs, you won’t have to run your AC harder during those hot months, further adding to your cost savings. You can be able to see such consumption trends over the months through the energy management system, getting to the root cause of the problem. For instance, seeing the changing trends in the AC energy consumption over different weeks will enable you to assess what is causing it to be pushed harder, and address the root cause of the problem.

Acquiring energy-efficient office equipment

This is broad, with the changes being made here depending on your particular niche. Take printers for instance. Simply going for printers with sleep and automatic shut-off modes will ensure that the units are not consuming energy when they are not in use. The same case applies to copier machines. Energy saving surge protectors on the other hand are beneficial for allowing you to “unplug” multiple devices that use standby power even when switched off – what’s usually called “vampire power” or “phantom energy“.

The need for energy savings cuts across the board, from the computers and monitors used, to the coffee makers and kettles. For instance, working with an electric kettle to heat water for tea beats using a microwave or stove. Go further by opting for a kettle that allows you to set the particular temperature you want for the water – since you don’t really need the water for tea to be boiling hot for the tea to properly steep. Taking such steps further contributes to your business’ efforts to go green and reduce your carbon footprint.

Turning to renewable energy sources

Switching to renewable sources to power your operations will simultaneously reduce your energy bills and cut your carbon emissions. From solar panels to wind turbines and the like, they are cleaner sources of energy, and the installations that you go with will depend on your kind of business. Moreover, this will protect you from the fluctuations in energy prices, since the bills are affected by the availability of fuel, electricity demand, costs that go into generating and distributing it – all of which end up hitting your business in the long run. On the other hand, going off the grid with your own supply of power protects you from this. In fact, if you end up producing surplus energy, you can sell it back to the grid, earning your business extra revenue.

Sure, the upfront costs of setting up the systems will take a sizable chunk out of your budget, but the savings allow you to recoup the costs over time. In addition, there will be savings from the incentives being provided by the government, such as tax rebates and grants. These are the likes of the Solar PV Grant from SEAI (Sustainable Energy Authority of Ireland) which is at €900 per kWp, capped at €2400 for each business. Funding is available for homes, community programs and commercial buildings such as Collinstown Park School that was able to slash their lighting costs by a whopping 90% after securing 50% of the funding for their energy upgrade project from SEAI. The ecoVaro EMS comes with support for solar power installations in its firmware, that way you can continue assessing the changes that your solar power system will bring to your overall energy usage.

Spread awareness

You should also carry out energy conservation training for your staff. The reports generated by the EMS will make it easy for them to get a picture of their energy consumption trends, and the effects that it has on both the performance of the company, and the carbon footprint as a whole. It also gives them more awareness of the impact that they each have at an individual level.

Assessing Key Performance Indicators

The energy analytics tools from the EMS will show you whether you are actually meeting your goals. Since it works with the different metered connections, from getting electricity and temperature readings, checking radiation levels, humidity data all through to gas meters, you will be able to assess the progress that your business is making across the board.

For ecoVaro in particular, the performance of your systems can be seen through reports like Consumption Charts – from the different offices, tenants and equipment energy usage, peak -and off-peak data, as well as Regression Charts that allow you to compare building’s actual energy consumption to its expected performance, and how they are affected by variables such as temperature.

With the site-by-site data and the monitoring being down to the sub-meter level, you will be able to identify an issue when it crops up and narrow it down to the specific instant and location where it occurred. This enables you to address the problem quicker.

Conducting a compliance audit

A comprehensive audit can then be undertaken to ensure that your company meets internationally-recognized standards that have been stipulated regarding implementing energy management systems and enhancing the energy efficiency of your operations. The compliance audits are carried out by certified auditors.

Through the EMS, you are able to position your business appropriately to meet the standards for your particular niche, measuring and observing the performance of energy-saving projects that have been implemented. This extends to acquiring and presenting data that will be used to show the business’s compliance to industry regulations and obtain the relevant certification. You are able to report on your carbon footprint, and verify it. This information can also be disseminated amongst your employees and customers, raising awareness about your business green initiatives, boosting your brand in the process.

Web Analytics

There’s a vast ocean of raw customer data on the Web. Ever thought of the implications if somehow you could harness all that data and transform it into useful information? Information that perhaps you can use in your SEO (Search Engine Optimisation) and conversion optimisation?

There are web analytics tools you can employ for these purposes. But using web analytics tools will only win you half the battle. You’ll have to be proficient in configuring these tools to generate insightful and actionable results out of them. A poorly configured tool can produce confusing or even misleading information.

Benefits of Integrating IoT and Field Service

Owing to the complexity of its definition, many people loosely use the phrase Internet of Things (IoT) without having a solid grasp of its true meaning. A majority in this category take IoT to be nothing more than the automation of home gadgets, where the internet is used to interconnect computing components embedded in everyday devices.

Granted, the whole idea of IoT got its roots from the home setting. Nevertheless, IoT has outgrown that spectrum and has since penetrated into almost every area of business and industry. By employing IoT, you can literally take full control of everything in your business using a single device. From assigning tasks to monitoring security, managing bills to tracking time, IoT has revolutionized the way business is done.

Interestingly, not so long ago, most technology experts limited their forecasts to machine-to-machine (M2M) integration and Augmented Reality (AR), which also, admittedly, hit the technology industry with an admirable suave. Back then, it could have been laughable for anyone to have suggested that IoT would be so commanding in almost every industry, including real estate, medicine, automobile, and more.

It’s not for nothing, therefore, that the field service industry has also embraced IoT, integrating it in the daily running of business activities, including tracking machine diagnostics, detecting breakdowns, and assigning field engineers to attend to customer needs.

How the Field Service Industry is Benefiting from IoT

Machine uptime has remained an ongoing concern for many customers. In the traditional approach, whenever a machine breaks down, the customer alerts the service provider and then the field service manager checks to see if there is any field engineer available for a new task. Once an engineer has been identified, he?s then dispatched to the site. This worked, but it resulted in an extended machine downtime, a terrible experience for customers.

Thanks to IoT, things are now happening differently.

IoT is now integrating machines to a central communications centre, where all alerts and status updates are sent. The notifications are instant. The field service manager, therefore, gets to learn of the status of machines at the exact time of status change. An engineer who?s not engaged would then be immediately assigned to undertake any needed servicing or repair.

By employing IoT, the service provider receives timely reports relating to diagnostics, machine uptime, part failures, and more. The field manager can, as a result, foretell and forestall any possible downtime.

How has this been helpful?

Before giving a definite answer to that question, it’s crucial to note that more than half of all field service organizations now employ IoT in their Asset Management Systems and Field Service Management. And to answer the question, all the organizations that have the two systems integrated using IoT experience twice as much efficiency as those that don’t, states an Aberdeen Group report. As you already know, improved efficiency results in a corresponding upshot in customer satisfaction.

Apps Making a Difference in IoT-Field Service

The integration of IoT into almost every aspect of business prompted the design and development of different applications to link computing devices. Since the advent of IoT, the software development for the technology has come of age. Powerful and lightweight apps that don simple yet beautiful user interfaces are now readily available at affordable price tags.

A good example of such an App is ecoVaro by Denizon.

ecoVaro not only helps businesses to monitor energy and other relevant environmental data such as Electricity, Gas, Water, Oil, Carbon, Temperature, Humidity, Solar Power, and more, but also provides analytics and comprehensive yet easy to understand reports. The data received from devices such as meters is converted into useful information that’s then presented in figures and graphs, thus allowing you to make decisions based on laid down controls.

The focus of the app is to instantly alert service engineers to go on site to fix issues.

With ecoVaro, field service engineers no longer have to return to the office to get new instructions. Also, customers don’t have to manually fire alerts to the service provider whenever something isn’t working correctly. By employing the latest in IoT, ecoVaro sends notifications to field service managers and engineers about respective customers that need support.

How ecoVaro Helps

Best-in-class companies aren’t ready to compromise on customer satisfaction. Therefore, every available avenue is used to address customer concerns with the deserved agility. By using IoT, ecoVaro makes it possible for field service providers to foresee and foreclose any possible breakdowns.

The inter-connectivity among the devices and the central communications centre results in increased revenue and improved interactivity between the system and the field engineers. This results in greater efficiency and lower downtime, which translates into improved productivity, accountability, and customer satisfaction, as well as creating a platform for a possible expansion of your customer base.

ecoVaro isn’t just about failed machines and fixes. It also provides diagnostics about connected systems and devices. With this, the diagnostics centre receives system reports in a timely manner, allowing for ease of planning and despatch of field officers where necessary.

Clearly, but using the right application, IoT can transform your business into an excellently performing field service company.
