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.

8 Reasons why you Need to Undertake Technical and Application Assessments

Are your information assets enabling you to operate more cost-effectively or are they just drawing in more risks than you are actually aware of? Obviously, you now need to get a better picture of those assets to see if your IT investments are giving you the benefits you were expecting and to help you identify areas where improvements should be made.

The best way to get the answers to those questions is through technical and application assessments. In this post, we?ll identify 8 good reasons why it is now imperative to undertake such assessments.

1. Address known issues – Perhaps the most common reason that drives companies to undertake a technology/application assessment is to identify the causes of existing issues such as those related to data accessibility, hardware and software scalability, and performance.

2. Cut down liabilities and risks – Unless you know what and where the risks are, there is no way you can implement an appropriate risk mitigation strategy. A technology and application assessment will enable you to thoroughly test and examine your information systems to see where your business-critical areas and points of failure are and subsequently allow you to act on them.

3. Discover emerging risks – Some risks may not yet be as threatening as others. But it would certainly be reassuring to be aware if any exist. That way, you can either nip them in the bud or keep them monitored.

4. Comply with regulations – Regulations like SOX require you to establish adequate internal controls to achieve compliance. Other regulations call for the protection of personally identifiable information. Assessments will help you pinpoint processes that lack controls, identify data that need protection, and areas that don’t meet regulatory requirements. This will enable you to act accordingly and keep your company away from tedious, time-consuming and costly sanctions.

5. Enhance performance – Poor performance is not always caused by an ageing hardware or an overloaded infrastructure. Sometimes, the culprits are: unsuitable configuration settings, inappropriate security policies, or misplaced business logic. A well-executed assessment can provide enough information that would lead to a more cost-effective action plan and help you avoid an expensive but useless purchase.

6. Improve interoperability – Disparate technologies working completely separate from each other may be preventing you from realising the maximum potential of your entire IT ecosystem. If you can examine your IT systems, you may be able to discover ways to make them interoperate and in turn harness untapped capabilities of already existing assets.

7. Ensure alignment of IT with business goals – An important factor in achieving IT governance is the proper alignment of IT with business goals. IT processes need to be assessed regularly to ensure that this alignment continues to exist. If it does not, then necessary adjustments can be made.

8. Provide assurance to customers and investors – Escalating cases of data breaches and identity theft are making customers and investors more conscious with a company?s capability of preserving the confidentiality of sensitive information. By conducting regular assessments, you can show your customers and investors concrete steps for keeping sensitive information confidential.

Why Spreadsheets can send the Pillars of Solvency II Crashing Down


Solvency II is now fast approaching and while it may provide added protection to policy holders, its impact on the insurance industry is not all a bed of roses. Expect insurance companies to restructure, increase manpower, and raise spending on actuarial operations and risk management initiatives. Those that cannot, will have to go. But what have spreadsheets got to do with all these?

Well, spreadsheets aren’t really the main casts in this blockbuster of a regulatory exercise but they certainly have a significant supporting role to play. Pillar I of Solvency II, which calls for improved supervision on internal control, risk management, and corporate governance, and Pillar II, which tackles supervisory reporting and public disclosure of financial and other relevant information, both affect systems that have high-reliance on spreadsheets.

A little background about spreadsheets might help.

Who needs an IT solution when you can have spreadsheets?

Everyone in any organisation just love spreadsheets; from the office clerk to the CEO. Because they’re so easy to use (not to mention they’re a staple in office computers), people employ them for processing numbers and as an all-around tool for planning, forecasting, reporting, complex modelling, market data analysis, and so on. They make such tasks faster and easier. Really?

You probably haven’t heard of spreadsheet hell

Unfortunately, spreadsheets do have certain shortcomings. Due to their inherent structure and lack of controls, it is so easy to commit simple errors like an accidental copy paste, an omission of a negative sign, an incorrect data input, or an unintentional deletion. Such shortcomings may seem harmless until your shareholders discover a multi-million discrepancy in your financial report.

And because spreadsheet errors can go undetected for a long time, they are constant targets of fraudsters. In other words, spreadsheets are high risk applications.

Solvency II Impact on Spreadsheet-based Financial and IT Systems

Regulations like Solvency II, are aimed at reducing risks to manageable levels. Basically, Solvency II is a risk-based system wherein a company?s capital requirements will depend on its measured riskiness. If companies want to avoid facing onerous capital requirements, they have to comply.

The three pillars of Solvency II have to be in place. Now, since spreadsheets (also known as User Developed Applications or UDAs) are high-risk applications with weak control features and prone to produce inaccurate reports, companies will have a lot of work to do to establish Pillars II and III.

There are at least 8 articles that impact spreadsheets in the directive. Article 82, for example, which requires firms to ensure a high level of data quality and accuracy, strikes at the very core of spreadsheets? weakness.

A whitepaper by Raymond Panko entitled ?Spreadsheets and Sarbanes-Oxley: Regulations, Risks, and Control Frameworks? mentioned that 94% of audited real world operational spreadsheets that were included in his study were found to have errors and that an average of 5.2% of all cells in the audited spreadsheets had errors.

Furthermore, many articles in the directive call for the enforcement of better documentation. This is one thing that’s very tedious and almost unrealistic to do with spreadsheets because just about anyone uses them. Besides, with different ‘versions? of the same data existing in different workstations throughout the organisation, it would be extremely difficult to keep track of them all.

Because of spreadsheets you now need an IT solution

It is clear that, with the growing number of regulations and the mounting complexity of tasks needed for compliance, spreadsheets no longer belong in this era. What you need is a server-based solution that allows for seamless collaboration, data reliability, data consistency, increased security, automatic consolidation, and all the other features that make regulation compliance more doable.

One important ingredient for achieving Solvency II compliance is sound data risk management. Sad to say, the ubiquitous spreadsheet will only expose your data to more risks.

Understanding Carbon Emissions

Carbon emission is one of the hottest issues in the world of energy and environment today. While it is supposedly an essential component of the ecosystem, it has already become a large contributing factor to climate change. Carbon emission might be good but abuse of this natural process has made it harmful to people across the globe.

This series of articles aims to help people understand the intricacies of carbon emission and what society can do to efficiently manage this natural occurrence.

Natural Carbon Cycle

Two important elements in the carbon cycle are carbon, which is present in every living thing all over the world; and oxygen, which is found in the air that people breathe. When these two bond together, they create a colourless and odourless greenhouse gas known as carbon dioxide, which is then crucial to trapping infrared radiation heat in the atmosphere and also for weathering rocks.

Carbon is not only found in the atmosphere of the earth. It is also an element found in oceans, plants, coal deposits, oil and natural gas from deep down the earth?s core. Through the carbon cycle, carbon moves naturally from one portion of the earth to another. Looking at this scenario, one can see that the natural carbon cycle is a healthy way to release carbon dioxide into the air in order to be absorbed again by trees and plants.

Altered Carbon Cycle

The natural circulation of carbon among the atmosphere is vital to humankind. However, studies show that humans misuse this natural cycle and abuse it instead. Whenever people burn fossil fuels such as coal, oil and natural gas, they produce carbon dioxide ? which is an excess addition to the natural flow of carbon in the environment. The problem is that the release of carbon dioxide is much more than what plants and trees can re-absorb. People are not only adding CO2 to the atmosphere, they are also influencing the ability of natural sinks, such as forests, to remove it from the atmosphere. Humans alter the carbon cycle by contributing doubled or tripled greenhouse gas to the atmosphere, faster than nature can ever eliminate. Worst, nature?s balance is destroyed.

The Result

Greenhouse gases include carbon dioxide, methane, nitrous oxide, fluorinated gas and other gases. Although these gasses contribute to climate change, carbon dioxide is the largest greenhouse gas that humans emit. The reason why people talk about carbon emissions most, is because we produce more carbon dioxide than any other greenhouse gas.

The increasing amount of carbon emissions cause global warming to become more evident. All the extra carbon dioxide causes the earth?s overall temperature to rise as well. As the temperature increases, climate also changes unpredictably. Flood, droughts, heat waves and hurricanes are now widely experienced even in places where these phenomenon never used to happen.

To be able to reduce the risk of more severe weather conditions means burning less fossil fuels and shifting more to renewable sources. This is never easy. But, definitely, it’s worth a try.
