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.

Top 10 Benefits of Using Field Service Automation Software

Just how much wastage is witnessed in your operations? Each morning your technicians report to work, they receive the day?s schedule, go through the inventory for the parts and tools that will be required, collect and fill the paperwork, before finally hitting the road- translating to hours of manual organisation. What of the information they need when they are at the site? Are they carrying around bulky files on each individual customer? Your field technicians are also responsible for lots of the equipment being handled- and you want to keep a tab on it all- knowing what is being worked on, when it is happening, how long it takes, and the materials that have been used. Dealing with all this on your end through loads of Excel sheets, calculating and updating time logs, and ticking off the inventory- it can be a strain. Field Service Automation Software comes in to handle it all- from the scheduling and tracking, to inventory control and invoicing- all on the same platform.

Eliminating the Paperwork and Optimising Your Operations

There has been a surge in demand for all-in-one Field Service Management (FSM) solutions. They leverage the power of mobile technology, cloud computing and social collaboration to boost the efficiency of field services. In fact, the FSM market is growing at rates never seen before, if the recent statistics are anything to go by. According to the latest estimates, it is worth $3.5 billion and is expected to hit $5.9 billion by 2024.

It’s understandable why this is happening. Technology is advancing, and we all know it’s every entrepreneur?s dream to optimise the use of the available resources while guaranteeing customer satisfaction. If technology can deliver this through automation, why not? Every business now wants to automate things, and the focus is to maximise resource output. You should, therefore, not be surprised to see the FSM software industry booming. If you just considered the field service industry, you’ll realise that there are so many software applications to help with service automation, whether full or partial.

A good example is FieldElite, which helps with the management of field workers. From your desktop or the palm of your hands, on a tablet or smartphone, you can take full control of your field workers, manage scheduled jobs, and use maps to manage work assignments for the already dispatched field workers. Not only does FieldElite help you handle tasks in an accountable manner but also provides options for accounting and reports, all managed in an easy to use dashboard.

10 Benefits Field Service Automation Software Brings On Board

Why would organisations need to invest in a Workforce management app? Below are some of the key benefits of using a Field Service Management software:

1. Cut down the down-time and make every minute count

From scheduling your operations, mapping out preferred routes, dispatching the service team, to staying connected with them throughout the tasks, you get to improve worker efficiency with field service software like FieldElite. 

Most FSM software programs allow the administrator to send tasks directly to the field worker?s mobile. More often than not, the FSM software provides vital information, including service history, optimal route to the site, the tools required, and contact numbers, among other details.

This improves efficiency by ensuring that the client’s needs are taken care of promptly. Where it’s about machine maintenance, the downtime would be as short as possible.

2. Enhance professionalism and boost your brand image

FSM software programs are known for ensuring professionalism in the manner in which business activities are conducted. Of course, professionalism is attained through several factors, including working with a team of professionals. Such a team, using FSM software, results in enhanced efficiency and excellence.

A field service software like FieldElite helps you to consolidate all your business information into a single central database. With different access levels, your employees will access only as much information as is relevant to their respective duties.

An FSM software is ideal because the stored information can be accessed from any location, meaning field workers can pick new tasks while in the field, provided they’ve got the requisite tools. Instead of having to come back to the office, the employee would access all the information and execute the necessary task.

3. Resource Optimisation with Real-time Field Service Automation Software

Resource optimisation is one of the key determinants of a company?s profitability. While businesses vary in size and purpose, they all share one thing in common ? the desire to increase productivity while ensuring the optimal usage of resources.

Besides productivity, field service software also allows for efficient utilisation of the available resources to cut down on costs.

4. Stay connected with all your crew- and coordinate them better

FSM software facilitates improved coordination with the workforce. The software streamlines the management of the entire field service life cycle, ranging from labour to work orders, returns, contracts, warranties, and equipment.

The idea is to bring all the company?s field-related operations to a central point. And now, with easy data accessibility from a central platform, improved coordination is easily achievable.

5. Get accurate data and make well-informed decisions every step of the way

Adopting the field service management software is more than just a way to improve efficiency. It goes a long way towards improving a company?s accuracy. When a field service management software is used to trace a company?s activities, all the tasks are tracked on the mobile device, keeping the managers informed of every step.

Besides, the technicians also have a free reign to record the diagnostics, quality information, test results, and the parts consumed. All the information can be captured using text, audio, videos, and still photos. This guarantees minimal to no instances of data manipulation.

6. Improve Customer Satisfaction: Win Their Loyalty

Field service management software improves customer satisfaction. How does that happen? Well, using a field service software like FieldElite allows for quick response to customer queries. If there?s one thing that quickly turns your customers off, it’s delayed response to their requests. With the field service management software, however, you can respond to such requests quickly and effortlessly.

Moreover, your customers can also track the service engineer to ensure they’re well informed of any anticipated delays. With quick response time, customer machines have more reliable up-time, which is the desire of every client.

7. Flexibility ? because no one likes being tied down

If there?s one thing that customers like when dealing with a company, it’s flexibility. Instinctively, customers will always want different options to choose from when using a service without appearing to be confined to one provision. Having limited options would also appear boring.

To this extent, it would be wiser to adopt advanced FSM software. Advanced FSM software is compatible with mobile phones, meaning users can easily manage their tasks from isolated locations. FSM software can either be device-agnostic or device-specific. The device-specific type supports Android, Windows, and Apple iOS. This guarantees mobile-friendly tasks where users can easily manage the assignments via mobile application.

8. Store client history in secure cloud-based FSM software

Software like FieldElite stores client history precisely. All the past data, including order history, are stored separately and accurately. In so doing, the field technician gets easy access to the tools, specifications, and technician instructions that aid them in their operations. The result is increased productivity and on-time service delivery.

9. Asset Management and Inventory Control

Naturally, companies offering different repair services have plenty of assets to store. Accordingly, retrieving a specific part out of the large collection would be daunting.

With a field service application like FieldElite, the staff members can track down all the products effortlessly using the GPS. Furthermore, the FSM software ensures excellent maintenance of assets.

10. Improve oversight of field workers ? and keep them in the loop

The FSM software comes with many useful tools, including a built-in GPS tracker. The GPS tracker oversees the operations of the on-field workers, providing precise details about their geographical location, actual arrival time, and most importantly, the distance from the job site.

While this might not be useful at all times, it comes in handy when you need to assign an urgent task to the nearby technician. Call it a classic example of dynamic scheduling.

Final Thoughts

With so much at stake, it’s increasingly compelling to include the Field Service Management Software in your business. With every industry moving towards automation, your business cannot afford to lag.

Quick and efficient service delivery through FSM software may be the difference between you and your competitors.

The FSM software is no longer the cherry on the cake but a must-have tool for your survival in the highly competitive market.

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 Volvo Dublin achieved Zero Landfill Status

The sprawling New River Valley Volvo plant in Dublin, Virginia slashed its electricity bill by 25% in a single year when it set its mind to this in 2009. It went on to become the first carbon-neutral factory in 2012 after replacing fossil energy with renewable power. Further efforts rewarded it with zero-landfill status in 2013. ecoVaro decided to investigate how it achieved this latest success.

Volvo Dublin?s anti-landfill project began when it identified, measured and evaluated all liquid and solid waste sources within the plant (i.e. before these left the works). This quantified data provided its environmental project team with a base from which to explore options for reusing, recycling and composting the discards.

Several decisions followed immediately. Volvo instructed its component suppliers to stop using cardboard boxes and foam rubber / Styrofoam as packaging, in favour of reusable shipping containers. This represented a collaborative saving that benefited both parties although this was just a forerunner of what followed.

Next, Volvo?s New River Valley truck assembly plant turned its attention to the paint shop. It developed methods to trap, reconstitute and reuse solvents that flushed paint lines, and recycle paint sludge to fire a cement kiln. The plant cafeteria did not escape attention either. The environment team made sure that all utensils, cups, containers and food waste generated were compostable at a facility on site.

The results of these simple, and in hindsight obvious decisions were remarkable. Every year since then Volvo has generated energy savings equivalent to 9,348 oil barrels or if you prefer 14,509 megawatts of electricity. Just imagine the benefits if every manufacturing facility did something similar everywhere around the world.

By 2012, the New River Valley Volvo Plant became the first U.S. facility to receive ISO 50001 energy-management status under a government-administered process. Further technology enhancements followed. These included solar hot water boilers and infrared heating throughout the 1.6 million square foot (148,644 square meter) plant, building automation systems that kept energy costs down, and listening to employees who were brim-full with good ideas.

The Volvo experience is by no means unique although it may have been ahead of the curve. General Motors has more than 106 landfill-free installations and Ford plans to reduce waste per vehicle by 40% between 2010 and 2016. These projects all began by measuring energy footprints throughout the process. ecoVaro provides a facility for you to do this too.
