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.

What Heijunka is & How it Smooths Call Centre Production

The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.

Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.

Smoothing Production in the Call Centre Industry

Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.

Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.

This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.

A Modern, More Flexible Approach

Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.

Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.

A Worked Factory Example

The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.

Predictability, Flexibility, and Stability at Call Centre Service

The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.

Reducing Your Carbon Footprint

Climate change creates a loud buzz across the globe. People are talking about how extreme the weather is, how polluted the environment has become or how devastating the results of carbon emissions are. While it is true that humans contribute a large impact to the worsening climate situations, people are also the most influential key towards making this world a better place. As much as the increase in carbon emissions results from what you do, the healthy change can also start in you.

Although it is a bit difficult to determine what you can do to help the society, do not be disheartened. The devastating forces may be massive for you to work through, but there are countless simple actions?you can take to reduce your carbon footprints day by day.

Home

While you are in the comfort of your home, you can start saving energy to reduce your carbon emission. You could’replace your standard light bulbs with compact fluorescent ones. A compact fluorescent bulb saves more than 2/3rds or up to 1,300 pounds of carbon dioxide in its lifetime. This bulb contains mercury, so make sure to choose a brand that has lower mercury than others.

Another thing, you can do to reduce your carbon footprint at home, is to mind your electronics. When you do not use your gadgets and appliances, make sure you unplug them. If you buy new ones, take time to look at the energy rating of the electronics to save you more energy in future use.

Alternative renewable energy is also a good thing to shift into. Try solar, hydro or wind power at home. Setting up your own residential solar panels and building your own turbines are excellent ways to choose green energy.

Food

The food industry is one of the largest contributors of carbon emissions. You may not have control over the food processing, but you can lower your carbon footprint by buying local products in the market. These local products are not transported from far off places, so the carbon dioxide released from them is lower compared to imported ones. Take a look at the packaging as well; less packaging means less waste.

If you have a big backyard, you could use your it to grow food. ?Eating food, either fruit or vegetable, which you grow at home is energy efficient. No more fuel combustion from transportation and other consequent food processing.

Travel

When you have your own car, accelerating it slowly and smoothly, as well as maintaining speed while driving will help lower your carbon emissions. If you drive a lot, it would be better to get a green car. As of now, you can consider using?public transportation and go for road travel rather than air travel when you take long distance trips. But when you need to take planes, better choose a non-stop flight instead of connecting ones.

Indeed, there are many ways you can combat global warming and climate change. The road to improved life quality through energy efficiency might be hard, but a transformed lifestyle can make a big difference. Start now ? lighten your carbon footprint and help save the world.

Can you do away with the Project Initiation Meeting?

Project initiation meetings are often skipped to fast-track projects. Once a sponsor is found, organisations go straight to project planning and execution. But based on our own experience, holding a project initiation meeting can actually eliminate many issues that may crop up in the future and hence may speed things up instead in the long run.

It is in the project initiation meeting where your project objectives and scope are clarified and all stakeholders are brought to the same page. Project sponsors and stakeholders will have to know in a nutshell what is needed from them, what the possible risks are, what different resources are required, and so on. So that, when it’s time to proceed to the next phase, everyone is already in-sync.

So what are taken up in such a meeting? Perhaps an actual example can help. Sometime in the past, we set out to work on an eCommerce website project. After conducting the project initiation meeting, these were some of the things we were able to accomplish:

  • Identified deliverables e.g. site design, interface to payment system, etc.
  • Come up with the project phases
  • Agreed what should be in and out of scope
  • Defined the acceptance test criteria
  • Identified possible risks
  • Identified the possible training and documentation work needed
  • Established whether any analysis was required, e.g. as with regards to payment interfaces
  • Formulated disaster recovery plans
  • Defined roles and responsibilities
  • Drafted timelines and due dates

Aren’t these covered in project planning? If the project is a big one, the answer is no. In a large project, project planning is a much more exhaustive activity. In a project initiation meeting, only the basic framework is defined.

Some questions may still remain unanswered after a project initiation meeting, but at least you already know what answers you need to look for. In the example we gave earlier, we left the meeting knowing that we needed:

  • a list of all necessary hardware to estimate the costs
  • to identify possible dependencies we might have with third parties
  • to identify what software had to be bought and what skills we needed to hire

When it was time to proceed to project planning, everyone involved already knew what direction we were taking. In effect, by not skipping the project initiation meeting, we were able to avoid many potential obstacles.
