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.
Month end accounting has always been a business critical exercise. Without the balance sheet, income statement, and other financial reports this exercise ultimately produces, management could not make informed decisions to keep the company in the right direction and at the ideal operational speed.
Now, in order to maintain optimal business velocity, month end activities have to be carried out as swiftly and as accurately as possible. Delays will only inhibit managers from reacting and effecting necessary adjustments in time. Inaccurate information, on the other hand, obviously lead to bad decisions.
But that’s not all. Never has the month end close been as demanding as it is today. Regulations like the Sarbanes-Oxley Act, Solvency II, Dodd-Frank Act, and others, which call for more stringent controls and more robust risk management practices, are now forcing companies to find better ways to face the end of the month.
Sticking to old month-end practices while striving to achieve regulation compliance can either cost a company more (if they add manpower) or simply bog it down (if they don’t). Among the worst of these practices is the use of spreadsheets.
These User Developed Applications (UDAs) are very susceptible to errors. (See spreadsheet risks)
What’s more, consolidating data from spreadsheets as well as carrying out reconciliations on them is very time consuming. These activities usually require data from outside sources – i.e. a workstation in a different department, building, or (in the case of really large corporations) geographical locations.
Furthermore, if one of these sources fail, the financial reports won’t be complete. This is not a far-fetched scenario, considering that spreadsheet storage and backup is typically carried out by the average end user. This leaves the spreadsheet data vulnerable to hard disk crashes, virus attacks, and unexpected disasters.
Thus, in order to produce accurate financial reports on time all the time, you need a financial/IT solution that offers optimal provisions for risk management, collaboration, backup, and business continuity.

These days, a business is as good as it is transparent. Businesses are on unsteady ground because of the ever changing face of social media and a never-seen-before demand for information. With many sources of info on the internet, being credible is a sure way of building trust and loyalty among clients.
Here is an example. Customers will always believe what they see. If they see the work you put into furnishing their favourite products, you have a greater chance of getting their approval. They can invest more in what they see. The clothing merchandise Patagonia did this for their Footprint Chronicles line to show how their jackets are made and worked out fine for them.
Transparency is a must. Nowadays, customers never forget when they feel cheated. It is even harder to ensure transparency because many clients are also experts who scrutinise every detail. So, how can you keep transparency at the forefront?
Have transparent workforce management
Customers always look for new information and want to be in the know. There is nothing worse than not being able find a product manual or an easy way to set up appointments. By giving your clients a self-service option, they can pick the services they want. This leaves more time to get stuff done rather than answering unending service calls from dissatisfied customers.
For instance, you could have a field service customer self-service application that allows customers to look for personalised services, a machine manual, book appointments, or solve any other problem. Customers then get feedback anytime. This one-on-one approach can help customers feel like their questions are being answered. They?ll also not go through the hassle of long hold times to reach an available customer service representative.
Create transparency in field service repair projects
If field technicians have access to field service software, it allows technicians to be more open to customers. This gives them vital information like customer history and the ERP, so that they can explain changes that were made after past enquiries and what is being done in current products. Such information can be a guide for future updates or let the techs suggest products that suit a client’s taste. Unlike always staying offline and out of touch with your client, using field service software can allow entry of allowances and mileage, and also let the customer know the delivery time for their products.
Show customers what they’re paying for
With field service automation, billing will also be transparent. By using the available information about your field service solution, the station can send updated service reports to the customer like mileage, allowances, parts, hours worked, and photos of broken parts from the service. After the customer authenticates the transaction with a signature, the field service agent can generate and sent to the customer an invoice based on the agreed upon services. In case allowances and mileage can be forwarded to the customer, it will be shown on the invoice.
Because you use field service automation, it means that the customer will receive the invoice really fast ? in days rather than weeks ? and transparency will skyrocket because the whole experience of the service will leave a permanent mark in their mind.
Mistaking information for transparency
Being honest with your customer is the one thing. Wasting their time with unnecessary information is another. Here is an experience I had with a small retailer. Tracking information is only useful if it has recent updates and is accurate. If the company want to use real time tracking, let them do so under one condition ? updates should be regular and on time so as not to leave the customer frustrated because they also make plans based on the same information. Late updates shed light on the nature of the service command. Everyone hates cooked-up real time information.
A company must not always have a one to one exchange of information with customers to maintain transparency..
Use simple language that all customers can understand
Don’t use abbreviations that only employees know
Never ever air your failures and flaws to your customers
It is interesting that most of the tools we use to keep in touch with our clients and servicing their requests can also be used to gather data and iron out possible errors to improve products and services. This is a good chance for service providers to evaluate and make necessary amendments.
There are some areas that will need improving while others will not, nevertheless, the client needs to always be informed and know why things are the way they are. Not all details should be told, so filter what you share.
5 ways field service supports customer service
Sales organisations are always in motion, working to deliver the right product to their customers. To keep customers smiling all times is hard and only needs close communication and fulfilling promises that were made to them. This is where the field service delivery team comes in. Field service can either meet this demand or fall short plummeting satisfaction rates.
This is a task that relies on right people using various parts and information to get the job done. No matter what, the customer always expects to get exceptional services whether it be over the phone, chats, in the field, online messaging, over email, or social media.
These five field service points are suitable for any business model and guarantee excellent company-client relations.
Proactive service
A proactive service gives more to the customer. More attention is given to the customer so that the right actions, deliveries and repairs are done. By getting everything right the first time, the customer has less to do ensuring that they are satisfied with the services.
However, the field service technician is flooded with a myriad of unpredictable situations; overheating equipment, stalled machines, and insufficient precaution. But through field management software, they get more data about the customer and type of service or parts expected and they easily ride through any storm and prevent future damage.
Transparency
Nothing frustrates a customer more than a schedule that delays repairs. They easily ditch you for better services elsewhere. By offering the customer a service where they book appointments based on their own availability, we can easily sync this to the technicians and manager?s calendar. This not only saves time but also money from otherwise idle equipment.
On-site and off-site collaboration
Having seamless communication between field and office technicians is vital. Field technicians need to know more about parts, repairs, client maintenance history, and predict what should be changed in the long run. The faster they do this the better.
There should be a system that creates and automates communication between field and office technicians. Let each have the upper hand when providing parts, products or services to the customer.
Flexibility
Information is key to field service agents. They make the first impression since they make the initial contact with clients. Regardless of the resources, the field technician must always be armed with mobile tools they will need to access online resources and be ready for any emergency.
Actionable performance improvements
Customers demand excellent service a company could offer. But as the game constantly shifts, the service management technicians must also come up with plans to stay up to par with competition. All these stems from coming up with KPIs, measuring them and turning them into a workable plan for the future.
For many people within the UK, water is not really something to worry about. Surely enough of it falls out the sky throughout the year that it does feel highly unlikely that we?ll ever run out of it. There certainly does seem to be an abundance of Branded Water available in plastic bottles on our supermarket shelves.
Water, water, every where, And all the boards did shrink; Water, water, every where, Nor any drop to drink.
Despite this, Once-unthinkable water crises are becoming commonplace. If you consider that In England and Wales, we use 16 billion litres of clean drinking water every day ? that’s equivalent to 6,400 Olympic sized swimming pools.
Currently, water companies can provide slightly more than we need ? 2 billion litres are available above and beyond what we’re using. In some areas, though, such as south east England, there is no surplus and, as such, these regions are more likely to face supply restrictions in a dry year.
If we take little moment to reflect on some of the most notable water related stories over the past few years, we’ll start to get a picture of just how real the potential and the threat of water shortages can be.
Reservoirs in Chennai, India?s sixth-largest city, are nearly dry right now. Last year, residents of Cape Town, South Africa narrowly avoided their own Day Zero water shut-off.
It was only year before that, Rome rationed water to conserve scarce resources.
Climate change is likely to mean higher temperatures which may drive up the demand for water (alongside population growth) and increase evaporation from reservoirs and water courses during spring and summer.
The impact of climate change on total rainfall is uncertain, but the rain that does fall is likely to arrive in heavier bursts in winter and summer. Heavier rain tends to flow off land more quickly into rivers and out to sea, rather than recharging groundwater aquifers.
A greater chance of prolonged dry periods is also conceivable. This combined with the harsh reality that no human population can sustain itself without sufficient access to fresh water.
If present conditions continue, 2 out of 3 people on Earth will live within a water-stressed zone by 2025
What is water stress?
Water stress is a term used to describe situation when demand for water is greater than the amount of water available at a certain period in time, and also when water is of poor quality and this restricts its usage. Water stress means deterioration in both the quantity of available water and the quality of available water due to factors affecting available water.
Water stress refers to the ability, or lack thereof, to meet human and ecological demand for water. Compared to scarcity, water stress is a more inclusive and broader concept.
Water Stress considers several physical aspects related to water resources, including water scarcity, but also water quality, environmental flows, and the accessibility of water.
Supply and Demand
Major factors involved when water scarcity strikes is when a growing populations demand for water exceeds the areas ability to service that need.
Increased food production and development programs also lead to increased demand for water, which ultimately leads to water stress.
Increased need for agricultural irrigation in order to produce more crops or sustain livestock are major contributors to localised water stress.
Overconsumption
The demand for water in a given population is fairly unpredictable. Primarily, based on the fact that you can never accurately predict human behaviour and changes in climate.
If too many people are consuming more water than they need because they mistakenly believe that water is freely available and plentiful, then water stress could eventually occur.
This is also linked to perceived economic prosperity of a give region. Manufacturing demand for water can have huge impact regardless whether water is actively used within the manufacturing process or not.
Water Quality
Water quality in any given area is never static. Water stress could happen as a result of rising pollution levels having a direct impact on water quality.
Water contamination happens when new industries either knowingly or unknowingly contaminate water with their industrial practices.
Largely, this can happen and frequently does so because these industries do not take effective control of monitoring and managing their impact on communal water supplies. Incorrectly assuming this is the responsibility of an additional third party like the regional water company.
The truth is, water quality and careful monitoring of it is all of our responsibility.
Water Scarcity
Simple increases in demand for water can in itself contribute to water scarcity. However, these are often preceded by other factors like poverty or just the natural scarcity of water in the area.
In many instances, the initial locations of towns or cities were not influenced by the close proximity of natural resources like water, but rather in pursuit of the extraction of other resources like Gold, Coal or Diamonds.
For Instance, Johannesburg, South Africa is the largest City in South Africa and is one of the 50 largest urban areas in the world. It is also located in the mineral rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade.
Johannesburg is also one of the only major cities of the world that was not built on a river or harbour. However, it does have streams that contribute to two of Southern Africas mightiest rivers – Limpopo and the Orange rivers. However, most of the springs from which many of these streams emanate are now covered in concrete!
Water Stress and Agriculture
Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.
The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of real-time data and utilize cloud-based storage and processing power to curate it.
Sentek?s technology can be found in remote places like Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.
This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily repositioned to other locations as crops rotate.
Peter Buss is convinced that measurement is a means to an end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By accurately monitoring water can be saved until when the plant really needs it.
Peter also emphasises that crop is the ultimate sensor, and that ?we should ask the plant what it needs?.
This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return.
The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.
There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us.
Ecovaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.
A Quarter of the World?s Population, Face High Water Stress
Data from WRI?s Aqueduct tools reveal that 17 countries? home to one-quarter of the world?s population?face ?extremely high? levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year.
Water stress poses serious threats to human lives, livelihoods and business stability. It’s poised to worsen unless countries act: Population growth, socioeconomic development and urbanization are increasing water demands, while climate change can make precipitation and demand more variable.
How to manage water stress
Water stress is just one dimension of water security. However, like any challenge, its outlook depends on adequate monitoring and management of environmental data.
Even countries with relatively high water stress have effectively secured their water supplies through proper management by leveraging the knowledge they have garnered by learning from the data they gathered.
3 ways to help reduce water stress
In any geography, water stress can be reduced by measures ranging from common sense to innovative technology solutions.
There are countless solutions, but here are three of the most straightforward:
1. Increase agricultural efficiency: The world needs to make every drop of water go further in its food systems. Farmers can use seeds that require less water and improve their irrigation techniques by using precision watering rather than flooding their fields.
Businesses need to increase investments to improve water productivity, while engineers develop technologies that improve efficiency in agriculture.
2. Invest in grey and green infrastructure: D Data produced by Aqueduct Alliance – shows that water stress can vary tremendously over the year. WRI and the World Bank?s researchshows that built infrastructure (like pipes and treatment plants) and green infrastructure (like wetlands and healthy watersheds) can work in tandem to tackle issues of both water supply and water quality.
3. Treat, reuse and recycle: We need to stop thinking of wastewater as waste.
Treating and reusing it creates a ?new? water source.
There are also useful resources in wastewater that can be harvested to help lower water treatment costs. For example, plants in Xiangyang, China and Washington, D.C. reuse or sell the energy- and nutrient-rich byproducts captured during wastewater treatment.
Summary
The data is undeniably clear, there are very worrying trends in water.
Businesses and other other organisations need to start taking action now and investing in better monitoring and management, we can solve water issues for the good of people, economies and the planet. We collectively cannot kick this can down the road any further, or assume that this problem will be solved by others.
It is time, for a collective sense of responsibility and for everyone to invest in future prosperity of our Planet as a collective whole. Ecological preservation should be at the forefront of all business plans because at the end of the day profit is meaningless without an environment to enjoy it in!
