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.

Why DevOps Matters: Things You Need to Know

DevOps creates an agile relationship between system development and operating departments, so the two collaborate in providing results that are technically effective, and work well for customers and users. This is an improvement over the traditional model where development delivers a complete design ? and then spends weeks and even months afterwards, fixing client side problems that should never have occurred.
Writing for Tech Radar Nigel Wilson explains why it is important to roll out innovation quickly to leverage advantage. This implies the need for a flexible organisation capable of thinking on its feet and forming matrix-based project teams to ensure that development is reliable and cost effective.
Skirmishes in Boardrooms
This cooperative approach runs counter to traditional silo thinking, where Operations does not understand Development, while Development treats the former as problem children. This is a natural outcome of team-centred psychology. It is also the reason why different functions pull up drawbridges at the entrance to their silos. This situation needs managing before it corrodes organization effectiveness. DevOps aims to cut through this spider web of conflict and produce faster results.

The Seeds of Collaboration

Social and personal relationships work best when the strengths of each party compensate the deficiencies of the other. In the case of development and operations, development lacks full understanding of the daily practicalities operating staff face. Conversely, operations lacks ? and should lack knowledge of the nuances of digital automation, for the very reason it is not their business.
DevOps straddles the gap between these silos by building bridges towards a co-operative way of thinking, in which matrix-teams work together to define a problem, translate it into needs and spec the system to resolve these. It is more a culture than a method. Behavioural change naturally leads to contiguous delivery and ongoing deployment. Needless to say only the very best need apply for the roles of client representative, functional tester and developer lead.

Is DevOps Worth the Pain of Change?

Breaking down silos encroaches on individual managers? turf. We should only automate to improve quality and save money. These savings often distil into organisational change. The matrix team may find itself in the middle of a catfight. Despite the pain associated with change resistance, DevOps more than pays its way in terms of benefits gained. We close by considering what these advantages are.

An Agile Matrix Structure ? Technical innovation is happening at a blistering rate. The IT industry can no longer afford to churn out inferior designs that take longer to fix than to create. We cannot afford to allow office politics to stand in the way of progress. Silos and team builds are custodians of routine and that does not sit well with development.

An Integrated Organization ? DevOps not only delivers operational systems faster through contiguous testing. It also creates an environment whereby cross-border teams work together towards achieving a shared objective. When development understands the challenges that operations faces ? and operations understands the technical limiters – a new perspective emerges of ?we are in this together?.

The Final Word ? With understanding of human dynamics pocketed, a DevOps project may be easier to commission than you first think. The traditional way of doing development – and the waterfall delivery at the end is akin to a two-phase production line, in which liaison is the weakest link and loss of quality inevitable.

DevOps avoids this risk by having parties work side-by-side. We need them both to produce the desired results. This is least until robotics takes over and there is no longer a human element in play.

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.

What Heijunka is & How it Smooths Call Centre Production

The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.

Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.

Smoothing Production in the Call Centre Industry

Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.

Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.

This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.

A Modern, More Flexible Approach

Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.

Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.

A Worked Factory Example

The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.

Predictability, Flexibility, and Stability at Call Centre Service

The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.
