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.

Computer Forensics

So you had a customer data security breach last weekend? Do you know you could be held liable in court for failing to implement required security procedures? That’s right. Due to the overwhelming surge in identity theft wherein nearly 20 million Americans have already been affected, most states have enacted laws to curtail this fast rising crime. Therefore, it is important to redefine how your company deals with customer data security.

  • First, you’ll want to know what your obligations are as dictated by law. Some places, for example, require the destruction or deletion of personal data through shredding, erasing, or by rendering them undecipherable.
  • Second, not only do you need to comply with the said requirements, you’ll also have to prove in court that you actually complied if ever a security breach does happen.
  • Third, you need to be aware of your post-breach duties to avoid being dealt additional penalties.

Obviously, such situations now call for individuals who are experts in both the legal and technical aspects regarding data security. Such individuals are practitioners of a relatively new discipline known as computer forensics.

Armed with our computer forensics specialists, we’ll be able to help you deal with the above concerns. As a result, you can be prevented from having to pay fines that can go up to hundreds of thousands of euros.

There are other equally important reasons why you would want to avail of computer forensics services. For example, you’ll need computer forensics specialists because you want to:

  • Catch a person involved in criminal activities such as child porn, stealing of personal data, and destroying intellectual property.
  • Investigate a computer, network, or even a mobile device for clues that may lead to the culprit.
  • Determine the extent and possible causes when you discover your digital data has been damaged.
  • Find and recover damaged, deleted or encrypted data regardless of whether the cause was intentional or not. If the data in question will be used as evidence in a legal action, there are certain procedures that need to be followed during recovery operations to retain the integrity of the data. Computer forensic specialists are highly qualified for such operations.
  • Implement security policies in your organisation. Such policies have to operate within legal bounds if you want to avoid possible sanctions in the future. These policies should also be designed such that future forensic operations can be conducted with a high likelihood of success.

That said, a company that integrates computer forensics into its IT security policies and practices will be better equipped to remedy the situation once data security has already been compromised than a company that doesn’t.

The Future of Cloud Backup and Recovery

We came across a post on Docurated that pulled together thirty-seven suggestions for the top cloud storage mistakes user companies make. Given that cloud storage seems to be the best backup solution for now at least, we decided to turn these ideas around to sense the direction cloud backup and recovery needs to take, if it is still to be relevant in say ten years? time.

Has Cloud Storage Largely Saturated the West?
It probably has. Outside of major corporates who make their own arrangements ? and SME?s that use free services by email providers ? the middle band of companies in Europe and America have found their service providers, although they may have never tested the recovery process, to see if it works.

The new gold rush in the cloud backup and recovery business is, or should be emerging markets in Asia, Africa, South America, and the Middle East. There, connectivity is brittler than over here. To be relevant in these fragile, more populous areas our cloud backup and recovery industry need to be more agile and nimble.

? It must provide a simpler service emerging commerce can afford, refresh its user interfaces in third world languages, have more accessible help, and be patient to explain how cloud storage works to newbies. In other words, it must source its call centre operators in the areas it serves.

? It must adapt to local connectivity standards, and stop expecting someone with ADSL broadband to keep up with cloud server networks running at up to 1GBPS compared to their 10MBPS at best. For user sourcing and retention purposes, these new cloud backup and recovery services must be the ones who adapt.

? It must facilitate disaster recovery simulations among its clients in calmer moments when things are going well. Are they backing up the right files, are they updating these, and are their brittle ADSL networks able to cope with their cloud service providers? upload and download speeds?

? It must develop lean and agile systems slim enough to accommodate a micro client starting out, but sufficiently elastic to transfer them seamlessly to big data performance. The Asian, African, South American, and Middle Eastern regions are volume driven, and individual economies of scale are still rare.

? It must not expect its users to know automatically what they need, and be honest to admit that Western solutions may be wrong-sized. Conversion funnels in the new gold rush are bound to be longer. Engagements there depend on trust, not elevator sales letters. Our competition in these countries already works this way.

? It must be honest and admit cloud storage is only part of the solution. To recruit and retain users it must step back to 1983, when Compuserve offered its customers 128k of disc space, and spent an amount of effort explaining how to filter what to put there.

Cloud Storage of Data is Only One Part of the Solution
Governance reports and stock certificates burn just as easily as do servers in a fire. We must not transfer bad habits to exciting new markets. We close this article with the thoughts of John Howie, COO of Cloud Security Alliance, as reported in the Docurated post we mentioned, and these apply across the globe, we believe.
There is no single most important thing to carry forward into the future of cloud backup and recovery. We must be mindful when moving data that this can be fragile too. We must also create layers of backup the way insurance companies re-insure, that make any one cloud backup and recovery business redundant if it happens.
We hold the trust of our customers in our hands but trust is delicate too. We must cease trying to make a pile of money quickly, and become more interested in ensuring that data transferred back and forth is synchronised. The cloud backup and recovery industry needs only one notorious mistake, to become redundant itself in the ten years we mentioned.

How Bombardier Inc. scored a Bulls Eye

When travelling anywhere in the world on land, sea or air, chances are, you will travel courtesy of something made by aerospace and transportation company Bombardier based in Montreal, Canada. In 2009, it set itself the goal of carbon neutrality by 2020. In other words, it hoped to remove as much carbon dioxide from the atmosphere as it was putting in.

By 2012, Bombardier concluded it was not going to become carbon neutral by 2020 at its current rate of progress. It discounted purchasing carbon offsets because it believed it would serve its interests better by introducing new energy-saving products to market faster. That way, it would achieve its objectives vicariously through the decisions of its customers. But that was not all that forward-thinking Bombardier did. It also set itself the following inward-facing objectives:

  • Reduce carbon footprint through efficient use of energy and less emissions
  • Involve the Bombardier workforce to raise awareness of behaving responsibly
  • Implement sustainable initiatives to further reduce the company carbon footprint

Specific Examples

At its Wichita site, Bombardier (a) fitted a white roof and insulation reducing summer energy consumption by 40%, (b) added an energy recovery wheel to balance air circulation, and (c) introduced skylights with integrated controllers to lower energy consumption by lighting.

At Mirabel, it enhanced the flue-gas management system by adding a pressure differential damper.

At Belfast, Bombardier (a) optimised HVAC systems to reduce pressure on chilling and air-handling plants, (b) installed solar panels on the roof, and (c) obtained approval for a waste-to-energy plant that will convert 120,000 tonnes of non-recyclable waste material annually.

By the end of 2013, Bombardier had already beaten its immediate targets by:

  • Reducing energy consumption by 11% against 2009
  • Reducing greenhouse gas emission by 23% against 2009
  • Reducing water consumption by 6% against 2012

Future Plans

Bombardier will never stop striving to reach its goal of carbon neutrality by 2020. It has a number of other projects in the pipeline waiting for scarce resources to fund them. During 2014, it continued with energy efficient upgrades at its French, Hungarian, Polish, Swiss, and UK plants.

These include consumption monitoring systems, LEDs for workshop lighting, new heating systems, and outdoor energy-saving tower lighting. The monitoring is important because it helps Bombardier focus effort, and provides measured proof of progress.
