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 to carry out an Operational Review

A mobile workforce management software is key to managing an efficient field workforce.? Managing a staff of people can be tricky in any industry. Try keeping track of employees on shifting jobsites, many whom are paid hourly or temporary workers. The added pressure of ensuring the right workers get to the right sites at the right times, but they also need to track hours, parts used, vehicles and equipment assets.

In a previous post, we defined what is an operational review and why they play a key process in the continual evolution of successful businesses.?

Operational reviews allow the organization members to evaluate their performance, according to the procedures, resources properly, timescales and budgets.

In this post, we’ll take a closer look at how to implement an operational review and the steps typically undertaken to help you and your organisation to implement an operational review.

What the steps in a Operational Review Process

There are typically six steps in an operational review that range from preparatory work conducting interviews and collecting documents to the presentation of the final written report.

An audit should be customized to meet a organisatons specific needs, so standard steps can and should only serve as a guideline.? Management and internal and external auditors should adjust the process to address the company’s particular goals and objectives.

Initial Management Meeting

Understanding the problem is the first crucial step of an operational review. This is one of major areas of discussions when the audit team meets with the management, and department heads will be asked to identify any specific areas of concern. Once the problem is identified, it would be easier to come up with workable solutions.

Conduct Interviews

The next step in the evaluation is carried out with experienced teams doing interviews and keeping close observation. Each team essentially watches how employees carry out their responsibilities. This is considered a key part of the process.

When doing the interview, it is also vital that the observing team gains the employees? trust and confidence. Likewise, the staff must be assured that whatever transpires between the team and the employee will be kept confidential. Management must therefore guarantee anonymity to anyone who offers critical information, lest employees withhold vital information and render the data gathered inaccurate.

Systems Review

Employees and management practices will be reviewed by the assessing team according to the standard policies and guidelines of the company. The effectiveness of the controls in place as well as their appropriateness to the current operating conditions will also be evaluated.

Reporting

A documentation of the data gathered and the assessment of the evaluating team, will be submitted to the management after the review process. Flow charts and written narratives of departmental activities are usually part of this report. This is also where observations and recommendations of the team will be presented to the department heads concerned.

Review Results

While the operational review is being conducted, it is important to take into account the vital factors that affect the company: the people, processes, procedures, and strategies. These four factors can determine the company?s progress in the future.

Key Areas of focus in operation reviews

At a minimum an operational review should include the following key ares of assessment

Management Control

Responsibilities, authority, and the scope in which an employee has the freedom to act must be clearly defined and documented. A complete and specific job description for instance, would give the employee a clear perspective on how he acts and functions within the company.

Boundaries should be set not only to benefit the employer but more so the employee as well.

Moral and Ethical Guidelines

Moral and ethical guidelines are just as important to ensure for a smoother employer?employee relationship. Otherwise, personal issues such as work ethics, work attitude and personal values may post problems in the long run if such guidelines are not drawn properly before relationships are established.

Processes and procedures

Evaluating processes is only beneficial if the company itself updates its processes and procedural manuals regularly, or at least when needed. Such protocols may need revision and some steps may be obsolete already. Improving a company?s processes and procedures doesn’t always entail cost. In fact, improvised procedures may even be cost-effective and could make the processes more manageable.

Communication and reporting standards

Gaps in communication could result in serious lapses in internal controls, putting the company and/or its assets at risk. This is where the importance of timely and clear communication comes in. Likewise, reports must be useful, and the flow of information and how it is processed must keep pace with the company?s growth.

Information technology (IT) and security controls can also be included under the communication clause. Proper IT security policies must be in place, state-of-the-art protection techniques employed, and everything be documented, periodically updated, and continually monitored.

Strategic planning and tactics

No company can ever be complete without its strategies. It would unwise for any organization to proceed without first knowing where it stands and what direction it wants to take. Strategic planning draws such a map. It must be aligned to the mission and vision of the company, and should also coincide with the organizational goals set. Strategic planning deals with these three key questions:

  • What do we do now
  • Whom do we do it for?
  • How can we overcome competition

Without clear strategic direction, expectations would likely differ between ownership and management.

Contingency planning, testing and recovery

Contingency plans must be up-to-date, and are essential to the organization. If one course of action fails, the company should have plan B, C and so on. In addition, an organization should be prepared to respond to interference’s.

This includes establishing a formal process to review transactions processing during both disruption and recovery.

Presentation of Report

Based on your objectives and our findings, we will develop detailed recommendations to improve your company?s performance and productivity. Our written report will include a list of both short-term and long-term projected improvements and courses of action, to be mutually agreed upon by both parties.

To ensure the achievement of the improvements we outlined, our team will also assist in the implementation of these modifications.

The plan has three levels of recommendations: one for executives, another for management, and a third one for staff.

The executive summary concentrates on your company?s strengths, weaknesses, opportunities and threats to its entirety. It includes recommendations for any needed changes in policy or governance.

The management plan is based on employee feedback and includes areas of immediate improvement as well as identification of potential problem areas. Concerns from the bottom level management can now be forwarded to the top level management in formal writing. Better working relationships may evolve from this, thereby setting the work environment for a higher productivity ratio.

Lastly, the staff report deals with topics like charting the hierarchy of the organization, and discussing in detail specific control objectives that are critical to the company?s mission. Part of our goal is to encourage personnel to pay close attentions to such changes, if any, as these efforts are essential if they want to bring about both organizational and personal success.

If you would like to further discuss how our operational review services can benefit your company, please feel free to contact us at your convenience to schedule an initial consultation. We?ll be more than happy to assist you.

Are Target Operating Models strategic compasses?

The short answer is they usually are, because every organisation needs a road-map of where they are going. Target operating models can be complex documents with illustrative details including project management structures, special tools, implementation procedures and management metrics. They can also be simple statements, as for example Winston Churchill?s promise that ?we shall fight them on the beaches, on the landing grounds and in the fields? which gave Britain the strategic direction it needed.

Many initiatives unfortunately fail because managers are ?too busy? to bottom on what their target operating model should say, or simply don’t believe in paperwork. As a result, promising initiatives may blunder off course or die a slow death without them really noticing. We cannot manage what we cannot measure, which is where the management metrics fit in. One of my favourite quotes is ?if you don’t know where you are going any road will get you there? which is what the Cheshire Cat said to Alice in Wonderland when she got lost.

The author blundered through life without a plan because there was no one else with his particular brand of imagination. The current business climate is different because everybody is trying to ramp up, and investors want to know exactly what is going to happen to their money and by when. Hence a target operating model can be indispensable throughout a change or product cycle.

The benefits of having a measurable operations / technology plan can produce powerfully tangible results if the organisation follows through on it. Built-in metrics with milestones are powerful tool for management, and, when they map through to the company financial plan almost irreplaceable as cash-flow forecasters.

Other benefits may include:

  • Shorter times to market and greater agility when launching new ideas
  • Reduced investor risk through a predictable process that’s readily monitored
  • A stable operating environment where there is consensus on direction
  • Greater likelihood of delivering on time and leading to repeat orders
  • A more cost-effective process, with less risk of loss of quality and money

Although it dates back a few years the Wills UK and Ireland Retail model still provides an excellent benchmark of a target operating plan that worked. The strategic goals were exceptionally clear, and they brought in a proven project manager to help them drive the program forward.

We have delivered advanced business management services to many of our clients, and believe you will find our personalised approach time-efficient and effective too.

Transformation to a process based organisation

Today’s global marketplace rewards nimble organisations that learn and reinvent themselves faster than their competition. Employees at all levels of these organisations see themselves as members of teams responsible for specific business processes, with performance measures tied to the success of the enterprise. As team members, they are “owners” of the process (or processes) to which they are assigned. They are responsible for both the day to day functioning of their process(s), and also for continuously seeking sustainable process improvements.

Transforming a traditionally designed “top down control” enterprise to a process-based organisation built around empowered teams actively engaged in business process re-engineering (BPR) has proven more difficult than many corporate leaders have expected. Poorly planned transformation efforts have resulted in both serious impacts to the bottom line, and even more serious damage to the organisation’s fabric of trust and confidence in leadership.

Tomislav Hernaus, in a publication titled “Generic Process Transformation Model: Transition to Process-based Organisation” has presented an overview of existing approaches to organisational transformation. From the sources reviewed, Heraus has synthesised a set of steps that collectively represent a framework for planning a successful organisational change effort. Key elements identified by Hernaus include:

Strategic Analysis:

The essential first step in any transformation effort must be development of a clear and practical vision of a future organisation that will be able to profitably compete under anticipated market conditions. That vision must be expected to flex and adjust as understanding of future market conditions change, but it must always be stated in terms that all organisational members can understand.

Identifying Core Business Processes:

With the strategic vision for the organisation in mind, the next step is to define the core business processes necessary for the future organisation to function. These processes may exist across the legacy organisation’s organisational structures.

Designing around Core Processes:

The next step is development of a schematic representation of the “end state” company, organised around the Core Business Processes defined in the previous step.

Transitional Organisational Forms/ Developing Support Systems:

In his transformation model, Hernaus recognises that information management systems designed for the legacy organisation may not be able to meet the needs of the process management teams in the new organisation. Interim management structures (that can function with currently available IT system outputs) may be required to allow IT professionals time to redesign the organisation’s information management system to be flexible enough to meet changing team needs.

Creating Awareness, Understanding, and Acceptance of the Process-based Organisation:

Starting immediately after the completion of the Strategic Analysis process described above, management must devote sufficient resources to assure that all organisation members, especially key managers, have a full understanding of how a process-based organisation functions. In addition, data based process management skills need to be provided to future process team members. It is not enough to schedule communication and training activities, and check them off the list as they are completed. It is critical that management set behavioural criteria for communication and training efforts that allow objective evaluation of the results of these efforts. Management must commit to continuing essential communication and training efforts until success criteria are achieved. During this effort, it may be determined that some members of the organisation are unlikely to ever accept the new roles they will be required to assume in a process-based organization. Replacement of these individuals should be seen as both an organisational necessity and a kindness to the employees affected.

Implementation of Process Teams:

After the completion of required training AND the completion of required IT system changes, process teams can be formally rolled out in a planned sequence. Providing new teams with part time support by qualified facilitators during the firsts weeks after start-up can pay valuable long term dividends.

Team Skill Development and Continuous Process Improvement:

Providing resources for on-going skill development and for providing timely and meaningful recognition of process team successes are two keys for success in a process-based organisation. Qualified individuals with responsibility for providing training and recognition must be clearly identified and provided with sufficient budgetary resources.

The Hernaus model for transformation to a process based organisation is both well thought out and clear. His paper provides an ample resource of references for further study.
