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.

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.

New Focus on Monitoring Soil

There is nothing new about monitoring soil in arid conditions. South Africa and Israel have been doing it for decades. However climate change has increased its urgency as the world comes to terms with pressure on the food chain. Denizon decided to explore trends at the macro first world level and the micro third world one.

In America, the Coordinated National Soil Moisture Network is going ahead with plans to create a database of federal and state monitoring networks and numerical modelling techniques, with an eye on soil-moisture database integration. This is a component of the National Drought Resilience Partnership that slots into Barrack Obama?s Climate Action Plan.

This far-reaching program reaches into every corner of American life to address the twin scourges of droughts and inundation, and the agency director has called it ?probably ?… one of the most innovative inter-agency tools on the planet?. The pilot project involving remote moisture sensing and satellite observation targets Oklahoma, North Texas and surrounding areas.

Africa has similar needs but lacks America?s financial muscle. Princeton University ecohydrologist Kelly Caylor is bridging the gap in Kenya and Zambia by using cell phone technology to transmit ecodata collected by low-cost ?pulsepods?.

He deploys the pods about the size of smoke alarms to measure plants and their environment.?Aspects include soil moisture to estimate how much water they are using, and sunlight to approximate the rate of photosynthesis. Each pod holds seven to eight sensors, can operate on or above the ground, and transmits the data via sms.

While the system is working well at academic level, there is more to do before the information is useful to subsistence rural farmers living from hand to mouth. The raw data stream requires interpretation and the analysis must come through trusted channels most likely to be the government and tribal chiefs. Kelly Caylor cites the example of a sick child. The temperature reading has no use until a trusted source interprets it.

He has a vision of climate-smart agriculture where tradition gives way to global warming. He involves local farmers in his research by enrolling them when he places pods, and asking them to sms weekly weather reports to him that he correlates with the sensor data. As trust builds, he hopes to help them choose more climate-friendly crops and learn how to reallocate labour as seasons change.

What is Servitisation?

In the current generation, innovation has transformed industries, businesses, economies, and livelihoods. Those who’ve accepted to embrace the changes have prospered and remained afloat and relevant in their respective industries.?

However, failure to embrace change has seen companies like Blockbuster pushed out of business by more innovative and technology-oriented companies like Netflix.?

What does this tell you?

That the only way to stay in business, despite the many challenges your business could be facing, is to remain alert to the dynamic demands of customers, many of which are dictated by technological advancements.?

So, if you’re a manufacturer and you’re keen on diving deeper into technology to stay on top of the game and beat your competition, you must also be expectant of the fast-approaching servitisation-centred economy. Companies like Rolls Royce that have already embraced servitisation are making great gains in their areas of expertise.?

What is Servitisation?

Servitisation can be defined as the transformation of a manufacturing firm from the mere offering of products to the market to providing innovative and invaluable services alongside their products. By so doing, the sale becomes an ongoing engagement and not a one-off event. Cranfield University professors call it “the innovation of an organisation’s capabilities and processes to better create mutual value through a shift from selling a product to selling product-service systems.”?

As foreign as it may seem for some professionals, servitisation has been a need that, though not embraced, its demand remains evident. Nonetheless, firms have hesitated to implement it. Shifting from manufacturing products only to incorporating product-centric services alongside the products is not a walk in the park. It boils down to completely changing the company’s entire structure and processes.

All the same, change is never comfortable, and that’s why it’s always best to focus on the positive for motivation.

Servitisation Case Study

Some manufacturing firms have already embraced servitisation, and they’re reaping big from it. They’ve understood the benefits of offering more value to customers at less cost. What Rolls Royce is doing currently with its “power-by-the-hour” program is a good example of servitisation.

Instead of selling Aero Engines and letting customers take charge of maintenance and uptime, Rolls-Royce now offers a full package that includes a product and relevant services.?

Essentially, what the company is creating is an intimate and long-term relationship with its customers.

The total care package by Rolls Royce means it’s essentially renting out its engines to customers and monitoring data for potential maintenance needs. The plan guarantees that maintenance is only done when necessary and avoidable damage detected in good time. As a result, there is a clear reduction in the overall cost.

Initially, Rolls Royce would make money by basically selling and repairing engines. That meant that the worse the engines, the more repairs required and the more the money the company would make.?

However, things changed when the company realised there is no demand for a product that’s constantly in the repair shop. That prompted Rolls Royce to embrace servitisation.

Servitisation aligns the interests of the customer and those of the manufacturer to ensure everyone benefits. Rolls Royce has been offering this package to airlines since 2010, and the company has seen significant returns as a result.

Benefits

There are several benefits of incorporating servitisation into your manufacturing firm. Below are three of the strongest benefits

  • Financial Stability– Servitisation establishes a more secure revenue stream because of the long term connection between manufacturer and customer. This also translates to loyal customers, meaning more profit.
  • Strong Customer Retention Rate– Being more experienced about the equipment and the constant tracking and monitoring that comes with servitisation; manufacturers are realising that they can keep more customers.
  • Selling a Solution And a Product– Today customers are not just looking to buy a product, instead, they want both the product and the solution to their problem. Meaning you make more money for the product you manufacture and the service you offer to your customers.

Implementation of Servitisation in the Industry

To effectively implement servitisation, there must be an effective two-way flow of information and data in the supply chain. Meaning you may require software like FieldElite for scalable condition monitoring of performance. With FieldElite, for example, servitisation is made easier for you because it enables you to monitor the performance of your assets remotely.

Maintenance and monitoring of assets were traditionally very expensive and time-consuming until the arrival of intelligent software that makes work easier and cost-effective for manufacturers. FieldElite uses advanced learning algorithms to remotely automate the entire process, allowing you to detect, in real-time, the performance and need for maintenance on your asset.

Required Organisational Changes

A few important steps include;

Companies that invest in continuous training and development always have a more competitive edge than their counterparts. Meaning an important step towards servitisation is training the workforce. This is important, considering that the company structure, focus, and process will have to change.

Set up a team that is focused on the challenge, change, and creation. With this, you can easily adjust to industry changes. The team should always work on knowing what should be adjusted and when it should be.?

In the shift to servitisation, adopting a comprehensive service technology is an important step. Such service technology software includes FieldElite. This technology will ensure that you’re able to monitor your product in real-time, meaning you can maintain good performance for as long as possible.

Because servitisation essentially focuses on the customer, take time to study customer behaviour. Knowing what your customers need and want will help you remain relevant in the industry.

Conclusion

As the demand for more benefits and long-lasting relationships with dealers grow, so is the need for manufacturers to adjust. Hence more and more manufacturing companies are leaning towards embracing servitisation as a solution to the growing demand.?

In turn, manufacturers who’re attaching service contracts to their product sales are making more than those who remain stuck in the traditional approach to sales.?

Essentially, servitisation will ensure that, as a manufacturer, you remain relevant to your customers now and in years to come. This is a much better arrangement in terms of saving costs and making more returns. Remember to be successful, you have to be flexible enough to change with demand.
