Six Sigma

Six Sigma has received much attention worldwide as a management strategy that is said to have brought about huge improvements and financial gains for such big-name companies as Allied Signal, General Electric (GE) and Motorola.

If you want to give your business the chance to attain the same resounding success, Six Sigma could be the method that will steer you towards that direction.

What is Six Sigma?

So what really is it? Six Sigma is a business management tool that was developed using the most effective quality improvement techniques from the last six decades. Basing its approach on discipline, verifiable data, and statistical calculations, Six Sigma aims to identify the causes of defects and eliminate them, thereby resulting in near-perfect products that meet or exceed customer’s satisfaction.

The core concept behind the Six Sigma method is that if an organisation can quantify the number of “defects” there are in a particular process, improvement activities can be implemented to eliminate them, and get as close to a “zero defects” scenario as possible. Defect here is defined as any process output that fails to meet customer specifications.

Six Sigma is also unique from other programs in that it calls for the creation of a special infrastructure of people within the organisation (“Champions“, “Black Belts“, “Green Belts“) who are to be expert in the methods.

Six Sigma Methodologies

When implementing Six Sigma projects, two methodologies are often employed. Although each method uses five phases each, these two are distinguished from each other using 5-letter acronyms and their specific uses.

DMAIC ? is the project methodology used to improve processes and maximise productivity of current business practices. The 5 letters stand for:

  • D ? Define (the problem)
  • M ? Measure (the main factors of the existing process)
  • A ??Analyse?(the information gathered to deter mine the causes of defects)
  • I ? Improve (the current process based on the analysis)
  • C ? Control (all succeeding processes so as to minimise additional defects)

DMADV – is the method most suitable if your business is looking to create new products or designs. The acronym stands for:

  • D ? Define (product goals as the consumer market demands)
  • M ? Measure (and identify product capabilities and risks)
  • A ??Analyse?(to create the best possible design)
  • D ? Design (the product or process details)
  • V ? Verify (the design)

How does Six Sigma differ from other quality programs?

If you think that Six Sigma is just another one of those business strategies that produce more hype than actual results, think again. Six Sigma uses three key concepts that sets it apart from other business management methods.

  • It is strictly a data-driven approach, where assumptions and guesswork do not figure in the decision making.
  • It focuses on achieving quantifiable financial results ? the bottom line ($) ? as much as giving emphasis on customer satisfaction.
  • It requires strong management leadership, while at the same time creating a role for every individual in the organisation.

Is Six Sigma right for your business?

While many other organisations such as Sony, Nokia, American Express, Xerox, Boeing, Kodak, Sun Micro-systems and many other blue chip companies have followed suit in adopting Six Sigma, the truth is, any company — whether you have a large manufacturing corporation, or a small business specialising in customer service.

Certainly, there is a lot more to Six Sigma than what you can probably absorb in one sitting or reading.

With our wide range of business management consultancy services, we can help you understand the Six Sigma method in the context of your business. We can also help you establish your improvement goals, set up your program, and train your own team of “champions” who can lead in implementing your Six Sigma goals.

Align IT Investments With Organization Goals

While some organisation leaders loathe spending on IT, a growing number are already convinced of the necessity of investing in it. Unfortunately, a substantial fraction of those convinced to pursue IT investments are misguided as to which initiatives are really contributory to reaching their organisation’s goals.

In the end, many of their purchases either end up underutilised or become white elephants altogether. There are also those difficult to spot – IT purchases that do become integrated into daily operations but have little effect on the organisation’s growth, positioning, profitability, or efficiency.

If a purchase is to cost your company a fortune, then its positive impact on established company objectives should reflect accordingly. But how would you know it would? You can’t hope to foresee all its benefits especially if the IT solution is still quite new to you.

Our job is not only to identify the strengths of an IT system but also to determine whether these strengths are at all useful to your organisation’s thrusts.

Basically, here’s what we’ll do:

  • Conduct a rigorous analysis of your organisation to determine the specific and overall impact of certain IT solutions. We’ll be looking for areas where the effects of IT can result in the most rapid reduction of costs and, at the same time, drive the organisation in the direction of its established goals.
  • Propose cohesive best-of-breed solutions in line with the results of our analysis. Our familiarity with the IT landscape and our extensive selection of contacts in the industry will allow us to conduct insightful picks from a vast field of choices.
  • Establish best practices to make sure IT investments are optimally utilised.
  • Perform periodic reviews to ensure practices and processes are still in line with the established goals.

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.

Do you really need a Cloud Broker?

A cloud broker is someone who can serve as your trusted adviser when it comes to your dealings with a cloud service provider. Sort of an IT consultant who: is familiar with cloud computing, can negotiate a mutually beneficial relationship between you and a provider, and help you manage usage, performance and delivery of cloud services.?But do you need one?

Is it even time for cloud adoption?

Of course, if you haven’t even started considering moving your IT systems to the cloud, what’s the point of reading this article, right? Well, if you’re running a business in Ireland or the UK maybe you should start thinking about it. The benefits (of moving to the cloud) are simply overwhelming. But then that’s for another post.

For now, let’s just briefly talk about the rate of cloud adoption so far. This should give you an idea what other decision makers nearby think about cloud computing and what they’ve done in this regard so far.

According to research conducted by the Cloud Industry Forum (CIF), the number of first-time users of cloud computing in the United Kingdom has risen by about 27% compared to last year.

The study, which was carried out by research company Vanson Bourne and which involved IT decision-makers from both the private and public sector in UK, also showed that 61% of companies are subscribing to cloud-based services. A similar research conducted last year (2011) revealed only 48%.

In Ireland, plans are underway to adopt cloud computing. According to Pricewaterhouse Coopers, 75% of Ireland’s CIOs and IT directors are already adopting a cloud computing strategy.

Definitely, the number of cloud adopters is growing. If that number already includes your hottest competitor, then perhaps there’s no time to waste.

But while a migration to the cloud should be in your pipeline, it shouldn’t be something you should rush into. Generally speaking, there are at least three kinds of services offered by cloud service providers: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).

Some providers offer variations of these services. You might only need one type of service or a little of everything. There are also technical and regulatory compliance issues that need consideration.

Obviously, if you have no idea where or how to start, you’ll need someone who can help you. But what kind of help do you need?

Let’s proceed by talking about the kinds of services cloud brokers offer as these are obviously indicative of the needs of current cloud customers.

What cloud brokers do?

Cloud brokers offer three main types of services.

Cloud?inter-mediation

Cloud inter-mediation services are designed to add value to existing services and improve capabilities. ?Examples of cloud inter-mediation include managing access to cloud-based services, carrying out performance reporting, and establishing stronger security.

Cloud aggregation

As mentioned earlier, some cloud customers may end up subscribing to multiple cloud services; most likely from different cloud service providers. To get optimal return on their various cloud subscriptions, these customers will need to apply data integration and make these disparate systems work together. They will also have to make sure data flowing from one system to another is kept secure. This is where cloud aggregation comes into play.

Cloud arbitrage

This entails finding the best cloud service provider(s) to solve a particular problem. One example is comparing different providers offering data storage services and identifying the one offering the most competitive rates.

Other cloud arbitrage brokers develop new solutions by combining the services of different cloud service providers and then offer them to cloud customers. While there are similarities between cloud arbitrage and cloud aggregation, the former is more flexible and allows the customer to transfer from one provider to another where conditions are more favourable.

Problems a cloud broker can help you solve

Just like with natural clouds, your experiences in cloud computing won’t be all white and fluffy. You’ll also encounter gray and uncertain (or even stormy) clouds.

One major issue in cloud computing is cloud security. In fact, cloud security (or the apparent lack of it) is the one thing that’s really clouding up the sky of cloud computing. But that doesn’t mean the cloud is totally insecure. Besides, there are certain types of information that really don’t require a high level of security. These types you can easily migrate to the cloud.

For sensitive information, you really need to conduct due diligence to make sure your cloud service providers’ data centres are secure enough.

Where exactly will your data be stored? Are there enough provisions for regulatory compliance? How will your data be segregated? Does the infrastructure readily support ?data forensics? Is there a sound disaster recovery/business continuity plan? These are just some of the questions that need clear answers before you sign a contract with a cloud service provider.

Also, before you sign, you need to study the SLA (Service Level Agreement) very carefully. Look at the guaranteed uptime. Is it enough to meet your own desired service levels?

Bear in mind that the answers to these questions may be too technical. This is one of those instances when a cloud broker can come in handy. As your trusted adviser, your cloud broker can break down the technical jargon and present everything in a language that you can make intelligent decisions from.

A cloud broker will also be able to study the cloud provider’s security architecture and policies and determine whether they’re sufficient to meet your own security requirements. Basically, a cloud broker will not only help you obtain answers to your questions.

He will also know exactly what vital information to extract from providers in order to ensure that you find the best deal possible.
