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 Alcoa Canned the Cost of Recycling

Alcoa is one of the world?s largest aluminium smelting and casting multinationals, and involves itself in everything from tin cans, to jet engines to single-forged hulls for combat vehicles. Energy costs represent 26% of the company?s total refining costs, while electricity contributes 27% of primary production outlays. Its Barberton Ohio plant shaved 30% off both energy use and energy cost, after a capital outlay of just $21 million, which for it, is a drop in the bucket.

Aluminium smelting is so expensive that some critics describe the product as ?solid electricity?. In simple terms, the method used is electrolysis whereby current passes through the raw material in order to decompose it into its component chemicals. The cryolite electrolyte heats up to 1,000 degrees C (1,832 degrees F) and converts the aluminium ions into molten metal. This sinks to the bottom of the vat and is collected through a drain. Then they cast it into crude billets plugs, which when cooled can be re-smelted and turned into useful products.

The Alcoa Barberton factory manufactures cast aluminium wheels across approximately 50,000 square feet (4,645 square meters) of plant. It had been sending its scrap to a sister company 800 miles away; who processed it into aluminium billets – before sending them back for Barberton to turn into even more wheels. By building its own recycling plant 60 miles away that was 30% more efficient, the plant halved its energy costs: 50% of this was through process engineering, while the balance came from transportation.

The transport saving followed naturally. The recycling savings came from a state-of-the-art plant that slashed energy costs and reduced greenhouse gas emissions. Interestingly enough, processing recycled aluminium uses just 5% of energy needed to process virgin bauxite ore. Finally, aluminium wheels are 45% lighter than steel, resulting in an energy saving for Alcoa Barberton?s customers too.

The changes helped raise employee awareness of the need to innovate in smaller things too, like scheduling production to increase energy efficiency and making sure to gather every ounce of scrap. The strategic change created 30 new positions and helped secure 350 existing jobs.

The direction that Barberton took in terms of scrap metal recycling was as simple as it was effective. The decision process was equally straightforward. First, measure your energy consumption at each part of the process, then define the alternatives, forecast the benefits, confirm and implement. Of course, you also need to be able to visualise what becomes possible when you break with tradition.

What is work force management?

For organisations to ensure they provide the right service.  In order to do they need to assign the right employees with the right skills to the right job at the right time to meet demand.

Workforce Management Background

Workforce management (WFM) is a strategy used by companies to increase their efficiency and performance. It entails all activities aimed at maintaining a steady output, such as human resource management, forecasting, field service management, budgeting, scheduling, performance and training management, analytics, recruitment and data collection.

Workforce management utilizes a unique set of performance enhancing tools and software to bolster corporate management, workers, and other categories of managers and supervisors in the manufacturing team, distribution, transportation, and retail operators. This is sometimes called HRM systems, or part of ERP systems, or workforce asset management.

Unlike the conventional outlay that only needed staff scheduling to improve time management, workforce management is now all-inclusive and demand-oriented to optimize staff scheduling. Apart from focusing on demand-orientation and optimization, workforce management also incorporates:

  • Estimating the workload and resource utilisation
  • Job scheduling
  • Management of working times and accounts
  • Monitoring the process of workforce management

Each task should be clearly defined and performed efficiently based on set engineering standards and methods of optimizing each task as much as possible. Out of this framework and demand based forecasts, workers are scheduled and given tasks, performance measured, give feedback, and incentives computed and paid.

Workforce management is an entire scheme aimed at building the capacity of workers, increase productivity and client relations, and where possible reduce labour costs.

What is Mobile Workforce Management (MWM)

Mobile workforce management (MWM) is a software-based service used to oversee employees outside of the institution?s premises; MWM sometimes refers to the field teams. Mobile workforce management encompasses all activities done to monitor and schedule the field workforce.

The entire process includes procurement, management and using mobile devices, applications and computer software. Related support services like tracking, logging, dispatch, productivity management, and other types of communication are also to make it efficient.

Companies do not have the same needs and MWM firms need to fine-tune their software and devices to sufficiently bridge this gap. Some providers are suited only to a specific type of company because of specialization, like managing the electric grid. This experience makes the MWM company suited to provide applications that are relevant to the company for them to continue operating smoothly and efficiently.

With the increase in mobile devices, applications, secured wireless networks and virtual desktop, there comes a stream of opportunities for small and medium-sized businesses (SMB) and other ventures. Nevertheless, a mobile workforce needs better controls, security and support, as well as a functioning mobile workforce management strategy.

MMS (managed mobility services) is often used interchangeably with MWM, but they should not be confused. MWM is related to software and applications used by mobile and computer devices to manage on-field work while MMS focuses on enterprises, and is like a way of keeping in touch with the company, other employees, and linking the mobile while at work to servers and the database.

Benefits of Mobile Workforce Management

MWM allows the utilization of technology to drive productivity. Here are the top five advantages of MWM..

  1. Customer focused. The customer is the backbone of any business. The team needs to keep in touch with up-to-date information about every interaction. In the end, better client relation makes sure that the customer is always happy.
  2. Information has the power to build or destroy. A cloud-based system is easier to manage and can help with collection of data which is used to make business decisions. This can help cut costs, increase the workforce support, and identify areas where polishing needs to be done.
  3. Improved efficiency. Mobile workforce management is majorly used in taskforce allocation. If the company adopts a cloud-based work force management system, allocation is done automatically saving a lot of time.
  4. Increased revenue. Each business seeks to maximize the profit. With cloud-based mobile workforce management some operations like task management, data analysis, customer communication, reporting, and performance monitoring can be automated. This reduces the costs incurred for multiple applications and saves time.
  5. Ease of communication. Communication is vital. Constant communication with customers drives sales rates and everyone loves that. Quick communication will help customers solve their problems faster and get instant feedback.

Additional WFM benefits

 Other WFM benefits are:

  • Operations are made efficient as all complex processes are automated.
  • Employers learn more about worker engagement, productivity and attendance, allowing them to modify training, coaching and processes aimed at streamlining performance.
  • Automation and easy manipulation of data to improve HR, productivity and slash administrative costs.
  • It increases employee productivity by reducing absenteeism and late arrivals.
  • Boosts the morale of employees by encouraging transparency and facilitating manager-employee communication.
  • WFM analyzes market and schedule requirements to pick the right employee with the best set of skills for a certain task.

Companies which embrace workforce management and mobile workforce management have a higher operational efficiency. They have lower operational costs and limit manual work as much as possible

Scrumming Down to Complete Projects

Everybody knows about rugby union scrums. For our purposes, perhaps it is best to view them as mini projects where the goal is to get the ball back to the fly-half no matter what the opposition does. Some scrums are set pieces where players follow planned manoeuvres. Loose / rolling scrums develop on the fly where the team responds as best according to the situation. If that sounds to you like software project management then read on, because there are more similarities?.

Isn’t Scrum Project Management the Same as Agile?

No it’s not, because Scrum is disinterested in customer liaison or project planning, although the team members may be happy to receive the accolades following success. In the same way that rugby players let somebody else decide the rules and arrange the fixtures, a software Scrum team just wants the action.

Scrum does however align closely ? dare I say interchangeably with Agile?s sprints. Stripping it of all the other stages frees the observer up to analyse it more closely in the context of a rough and tumble project, where every morning can begin with a backlog of revised requirements to back fit.

The 3 Main Phases of a Scrum

A Scrum is a single day in the life of a project, building onto what went before and setting the stage for what will happen the following day. The desired output is a block of component software that can be tested separately and inserted later. Scrumming is also a useful technique for managing any project that can be broken into discreet phases. The construction industry is a good example.

Phase 1 – Define the Backlog. A Scrum Team?s day begins with a 15 minute planning meeting where team members agree individual to-do lists called ?backlogs?.

Phase 2 – Sprint Towards the Goal. The team separates to allow each member to complete their individual lines of code. Little or no discussion is needed as this stage.

Phase 3 – Review Meeting. At the end of each working day, the team reconvenes to walk down what has been achieved, and check the interconnected functionality.

The 3 Main Phases of a Scrum ? Conclusions and Thoughts

Scrum is a great way to liberate a competent project team from unnecessary constraints that liberate creativity. The question you need to ask yourself as manager is, are you comfortable enough to watch proceedings from the side lines without rushing onto the field to grab the ball.
