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.

Data Leakage Prevention – Protecting Sensitive Information

When DuPont lost $400 million in intellectual property, it wasn’t because a hacker from the other side of the world infiltrated their system. The information was simply stolen by a former employee. Alarmingly, data loss incidents are not always caused by deliberate actions.

A file containing personal information accidentally attached to an email and sent to multiple recipients; financial data stored in a USB pen drive, accidentally left in a restaurant; or bank account data of colleagues, inadvertently posted on a company website – these are also some of the everyday causes of data loss.

A report done by research company Infowatch regarding global data leaks in 2010 showed that there were actually more accidental data leaks in that year compared to intentional ones. Accidental leaks comprised 53%, while intentional leaks comprised 42% (the rest were unidentified).

But even if they ?only? happened accidentally, breach incidents like these can still be very costly. The tens of thousands of dollars that you could sometimes end up paying in civil penalties (as in the case when you lose other people?s personal information) can just be the beginning. More costly than this is the loss of customer and investor confidence. Once you lose those, you could consequently lose a considerable portion of your business.

Confidential information that may already be leaking out right under your nose

With all the data you collect, process, exchange, and store electronically every day, your IT system has surely now become a storehouse of sensitive information. Some of them, you may be even taking for granted.

But imagine what would happen if any of the following trade secrets fell into the wrong hands: marketing plans, confidential customer information, pricing data, product development strategies, business plans, supplier information, source codes, and employee salaries.

These are not the only kind of data that you should be worried about. You could also get into trouble if your sloppy IT security fails to protect employee or client personal information such as their names; social security numbers; drivers license numbers; or bank account numbers and credit/debit card numbers along with their corresponding PINs.

In some countries, you could face onerous data breach notification requirements and heavy fines when these kind of data are involved.

There are now more holes to plug

It’s not just the different varieties of sensitive electronic information that you have to worry about. Because these data can take on different forms, i.e. data-at-rest, data-in-motion, and data-at-the-endpoints, you also need to take aim at different areas in your IT system.

Sensitive information can be found ?at rest? in each of your employees? hard disks, in your servers, storage disks, and in off-site backup disks. They can also be found ?in motion? in email, instant messaging, social networking messaging, P2P file sharing, ftp, http, and so on.

That’s not all. Your highly mobile workforce may have already introduced yet another high-risk area into your system: data-at-the-endpoints. This includes USB flash-disks, laptops, portable hard disks, CDs, and even smartphones.

The main challenge of data leak prevention

Having been made aware of the various aspects of data leakage, have you already come to grips with the extent of the task at hand?

There are two major things you need to do here to prevent data leakage.

One, you need to identify what data you have that can be considered as sensitive/confidential information. Of course you have financial information and employee salaries in your files. But do you also store personally identifiable information? Do you have trade secrets that are stored in electronic form?

Two, you need to pinpoint their locations. Are they only on your hard disks and laptops? Or have they made their way to flash drives, CDs/DVDs, or portable HDDs? Are they being transmitted through email or any other file transfer media?

The reason why you need to know what your sensitive data are as well as where they are is because you would like all efforts of securing them to be as efficient and unobtrusive as possible.

Let’s say, as a way of protecting your data, you decide to implement encryption. Since encryption can consume a lot of storage space and significantly reduce performance, it may be impractical to encrypt your entire database or all your files. For the same reason, you wouldn’t want to encrypt every single email that you send.

Thus, the best way would be to encrypt only the data that really need encryption. But again, you need to know what data needs to be encrypted and where those data can be found. That alone is no simple task.

Not only will you need to deal with the data you already have, you will also have to worry about the data that will go through your systems during the course of your day-to-day transactions.

Identifying sensitive data as it enters or leaves your system, goes through your network, or gets stored in your file system or database, and then applying the necessary security actions should be done automatically and intelligently. Otherwise, you could end up spending on a lot of man-hours or, worse, wasting them on a lot of false positives and negatives.

How Sustainable is Suez Environment

French-based Suez Environment works in the water and waste-management environment, with specific reference to water production, treatment, & pollution disposal, and waste treatment, recycling, incineration and site desensitisation. Its more than 65,000 employees distributed worldwide have participated in flagship projects like Renault’s goal of 95% reclamation of vehicle parts, and Lyonnaise des Eaux?s saving of 12 million cubic meters of water in a single year.

Suez Environment claims to have consistently increased the recovery rate of treated waste, decreased direct and indirect greenhouse gas emissions, and made significant inroads into the production of sustainable energy on behalf of its clients. But then surely that’s Suez Environment’s business, and with over 65,000 employees we are entitled to expect this. Given that there have been persistent allegations of privatised water distribution bumping prices up to the detriment of the poor, how effective is Suez Environment at practising what it preaches back home?

GDF Suez is its largest shareholder and includes it under its environmental and societal responsibility umbrella. This makes environmental performance an overarching goal alongside management systems, health and safety, risk and procurement, and ethics. Its environmental ambitions spin out into the following strategies:

  • Understand the interactions between our activities and the environment
  • Open dialogue with stakeholders and foster partnerships with them
  • Set quantitative and qualitative targets at all levels of the organisation
  • Achieve optimum balance between financial and environmental challenges
  • Be proactive; anticipate impacts on the environment and plan for them
  • Increase employee awareness through interactive training and education
  • Be constantly innovative; share successes within the organisation
  • Monitor progress continuously and publish measured results achieved.

These goals direct the Suez Environment management team?s attention towards optimising performance in key areas like greenhouse gases, energy management, renewable energy, biodiversity, responsible water management, pollution prevention and health and safety considerations.

Among numerous other examples, its waste incineration programs convert hazardous and conventional waste into heat used to generate electricity without requiring virgin carbon products. Elsewhere, the same energy warms market-gardening tunnels and work places on winter days.

Suez Environment uses sophisticated energy management software to analyse information that’s transmitted by data logging devices online. ecoVaro provides a similar service in the cloud. ecoVaro adapts to your requirements providing fresh insights to your business.
