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.

Spreadsheet Risks in Banks

No other industry perhaps handles such large volumes of critical financial data more than the banking industry. For decades now, spreadsheets have become permanent fixtures in the front-line reporting tool sets of banks, providing organised information when and where needed.

But as banks enter into a period of heightened credit risks, elevated levels of fraud, and greater regulatory scrutiny, many are wondering if continued reliance on spreadsheets is a wise decision for banks today.

The downfall of Lehman Brothers which eventually led to its filing for Chapter 11 bankruptcy protection on September 15, 2008, served as a wake up call for many institutions across the globe to make a serious examination of their own risk management practices. But would these reforms include evaluating the security of user developed applications (UDAs), the most common of which are spreadsheets, and putting specific guidelines as to when they can – or cannot be – used?

Banks and Spreadsheet Use

Banks have been known to utilise spreadsheets systems for many critical functions because most personnel are well-acquainted with them, and the freedom of being able to develop customised reports without needing to consult with the IT department offers flexibility and convenience. In fact, more than having a way to do financial budgeting and analysing customer profitability, even loan officers and trade managers have become reliant on spreadsheets for risk management reporting and for making underwriting decisions.

But there are more than a few drawbacks to using spreadsheets for these tasks, and the sooner bank executives realise these, the sooner they can adopt better solutions.

General Limitations

Spreadsheets are far from being data base systems and yet more often than not, they are expected to act as such, with figures constantly added and formulas edited to produce the presumably right set of reports.

In addition, data integrity is always a cause for concern as most values in spreadsheets are entered as manual inputs. Even the mere misplacement of a comma or a negative sign, or an inadvertent ?edit? to a formula can also be a source of significant changes in the outcome.

Confidentiality risk is also another drawback of the use of spreadsheets in banks as these tools do not have adequate?access controls to limit access to only authorised individuals. Pertinent financial information that fall into the wrong hands can lead to a whole new set of problems including the possibility of fraud.

Risks in Trading

For trading transactions, spreadsheets can prove to be of immense use – but only for small market volumes. As trade volumes increase and the types vary, spreadsheets are no longer a viable solution and may likely become more of a hindrance, with calculations taking longer in the face of bigger transaction amounts and growing transaction data.

And in trading, there is always the need for rigorous computational functions. Computing for the Value at Risk (VaR) for large portfolios for instance, is simply way beyond the capabilities of spreadsheets. Banks that persist in using them are increasing the risk of loss on those portfolios. Or, they can be opening up?opportunities for fraud?as Allied Irish Bank (in the case of John Rusnak – $690 million) learned the hard way.

Risks in Underwriting

Bankers who use spreadsheets as their main source of information for underwriting procedures also face certain limitations. Loan transactions require that borrowers? financial data be centralised and easily accessible to risk officers and lending officers involved in making decisions. With spreadsheets, there is no simple and secure way of doing that. Information can be pulled from different sources – individual tax returns, corporate tax documents, partnership documents, audited financial statements – hence there is difficulty in verifying that these reports adhere to underwriting policies.

Spreadsheet control and monitoring

Financial institutions which are having difficulty weaning themselves from the convenience and simplicity that spreadsheets offer are looking for possible control solutions. Essentially, they want to find ways that allow them to continue using these UDAs and yet somehow eliminate the?spreadsheet risks?and limitations involved.

Still, the debate goes back and forth on whether adequate control measures can be implemented on spreadsheets so that that the risks are mitigated. Many services have come forward to herald innovative solutions for better spreadsheet management. But at the end of the day, there really is no guarantee that such solutions would suffice.

Benefits of Integrating IoT and Field Service

Owing to the complexity of its definition, many people loosely use the phrase Internet of Things (IoT) without having a solid grasp of its true meaning. A majority in this category take IoT to be nothing more than the automation of home gadgets, where the internet is used to interconnect computing components embedded in everyday devices.

Granted, the whole idea of IoT got its roots from the home setting. Nevertheless, IoT has outgrown that spectrum and has since penetrated into almost every area of business and industry. By employing IoT, you can literally take full control of everything in your business using a single device. From assigning tasks to monitoring security, managing bills to tracking time, IoT has revolutionized the way business is done.

Interestingly, not so long ago, most technology experts limited their forecasts to machine-to-machine (M2M) integration and Augmented Reality (AR), which also, admittedly, hit the technology industry with an admirable suave. Back then, it could have been laughable for anyone to have suggested that IoT would be so commanding in almost every industry, including real estate, medicine, automobile, and more.

It’s not for nothing, therefore, that the field service industry has also embraced IoT, integrating it in the daily running of business activities, including tracking machine diagnostics, detecting breakdowns, and assigning field engineers to attend to customer needs.

How the Field Service Industry is Benefiting from IoT

Machine uptime has remained an ongoing concern for many customers. In the traditional approach, whenever a machine breaks down, the customer alerts the service provider and then the field service manager checks to see if there is any field engineer available for a new task. Once an engineer has been identified, he?s then dispatched to the site. This worked, but it resulted in an extended machine downtime, a terrible experience for customers.

Thanks to IoT, things are now happening differently.

IoT is now integrating machines to a central communications centre, where all alerts and status updates are sent. The notifications are instant. The field service manager, therefore, gets to learn of the status of machines at the exact time of status change. An engineer who?s not engaged would then be immediately assigned to undertake any needed servicing or repair.

By employing IoT, the service provider receives timely reports relating to diagnostics, machine uptime, part failures, and more. The field manager can, as a result, foretell and forestall any possible downtime.

How has this been helpful?

Before giving a definite answer to that question, it’s crucial to note that more than half of all field service organizations now employ IoT in their Asset Management Systems and Field Service Management. And to answer the question, all the organizations that have the two systems integrated using IoT experience twice as much efficiency as those that don’t, states an Aberdeen Group report. As you already know, improved efficiency results in a corresponding upshot in customer satisfaction.

Apps Making a Difference in IoT-Field Service

The integration of IoT into almost every aspect of business prompted the design and development of different applications to link computing devices. Since the advent of IoT, the software development for the technology has come of age. Powerful and lightweight apps that don simple yet beautiful user interfaces are now readily available at affordable price tags.

A good example of such an App is ecoVaro by Denizon.

ecoVaro not only helps businesses to monitor energy and other relevant environmental data such as Electricity, Gas, Water, Oil, Carbon, Temperature, Humidity, Solar Power, and more, but also provides analytics and comprehensive yet easy to understand reports. The data received from devices such as meters is converted into useful information that’s then presented in figures and graphs, thus allowing you to make decisions based on laid down controls.

The focus of the app is to instantly alert service engineers to go on site to fix issues.

With ecoVaro, field service engineers no longer have to return to the office to get new instructions. Also, customers don’t have to manually fire alerts to the service provider whenever something isn’t working correctly. By employing the latest in IoT, ecoVaro sends notifications to field service managers and engineers about respective customers that need support.

How ecoVaro Helps

Best-in-class companies aren’t ready to compromise on customer satisfaction. Therefore, every available avenue is used to address customer concerns with the deserved agility. By using IoT, ecoVaro makes it possible for field service providers to foresee and foreclose any possible breakdowns.

The inter-connectivity among the devices and the central communications centre results in increased revenue and improved interactivity between the system and the field engineers. This results in greater efficiency and lower downtime, which translates into improved productivity, accountability, and customer satisfaction, as well as creating a platform for a possible expansion of your customer base.

ecoVaro isn’t just about failed machines and fixes. It also provides diagnostics about connected systems and devices. With this, the diagnostics centre receives system reports in a timely manner, allowing for ease of planning and despatch of field officers where necessary.

Clearly, but using the right application, IoT can transform your business into an excellently performing field service company.

UK Government Updates ESOS Guidelines

Britain?s Environment Agency has produced an update to the ESOS guidelines previously published by the Department of Energy and Climate Change. Fortunately for businesses much of it has remained the same. Hence it is only necessary to highlight the changes here.

  1. Participants in joint ventures without a clear majority must assess themselves individually against criteria for participation, and run their own ESOS programs if they comply.
  2. If a party supplying energy to assets held in trust qualifies for ESOS then these assets must be included in its program.
  3. Total energy consumption applies only to assets held on both the 31 December 2014 and 5 December 2015 peg points. This is relevant to the construction industry where sites may exchange hands between the two dates. The definition of ?held? includes borrowed, leased, rented and used.
  4. Energy consumption while travelling by plane or ship is only relevant if either (or both) start and end-points are in the UK. Foreign travel may be voluntarily included at company discretion. The guidelines are silent regarding double counting when travelling to fellow EU states.
  5. The choice of sites to sample is at the discretion of the company and lead assessor. The findings of these audits must be applied across the board, and ?robust explanations? provided in the evidence pack for selection of specific sites. This is a departure from traditional emphasis on random.

The Environment Agency has provided the following checklist of what to keep in the evidence pack

  1. Contact details of participating and responsible undertakings
  2. Details of directors or equivalents who reviewed the assessment
  3. Written confirmation of this by these persons
  4. Contact details of lead assessor and the register they appear on
  5. Written confirmation by the assessor they signed the ESOS off
  6. Calculation of total energy consumption
  7. List of identified areas of significant consumption
  8. Details of audits and methodologies used
  9. Details of energy saving opportunities identified
  10. Details of methods used to address these opportunities / certificates
  11. Contracts covering aggregation or release of group members
  12. If less than twelve months of data used why this was so
  13. Justification for using this lesser time frame
  14. Reasons for including unverifiable data in assessments
  15. Methodology used for arriving at estimates applied
  16. If applicable, why the lead assessor overlooked a consumption profile
