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.

The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

Convert visits to sales to repeat purchases

The moment you start seeing more than a thousand unique visitors in just one day, we won’t be surprised if you’d be grinning ear to ear the entire week. But when weeks turn into months, you’ll then remember why you started off on this venture in the first place … and it wasn’t about just owning an immensely popular website.

People, like you, who’ve chosen to invest in eCommerce were most likely thinking along the lines of great ROI, revenues, and profits. Now that you have thousands of visitors, how would you like to have, say for a start, 1% of them buying the products on your site?

You know more about your own product prices; you do the math. But what might really interest you is that a slight change in that 1% conversion rate can already spell a big difference in your profits. Now imagine bringing that 1% up to at least 10%. That’s possible, but not if you simply rely on guesswork.

We rely on tests applicable to complex multi-variable systems, just like today’s typical eCommerce websites, in determining which combination of copy text, landing page images, form layouts, and background colours generate higher conversion rates.

Here’s how we’ll convert your visitors into buyers:

  • We’ll conduct A/B or even multivariate tests on your eCommerce website, thus eliminating guesswork in determining how to increase those conversion rates.
  • We’ll perform on-site and off-site web analytics to gain a deeper understanding of web usage to aid in our optimisation operations.
  • Through our expertise in copywriting, graphics and web designing, UI designing, and website QA, we can enhance and fine tune your site to give each visitor a uniquely engaging browsing experience.
  • We can also integrate CRM (Customer Relationship Management) systems so that you’ll have the technical advantage to turn one-time buyers into repeat customers.
Outsourcing

Are you ready to outsource? Do you even need to outsource? We’ll help you answer those and other questions regarding outsourcing and your company.

Once we’ve determined that outsourcing will render your organisation more focused on your core competencies, more cost-effective, and more flexible, we’ll offer you the full spectrum of our services. Our specialists can assist you in every stage of the entire outsourcing life-cycle.

Starting from evaluating what can be outsourced, through finding the right outsourcing service provider, building the contract and agreements, getting everything in place, and managing the outsourcing relationship – we’ll be with you every step of the way.

Learn more about some of the outsourcing services we offer:

Outsourcing Contracts and Agreements

When an outsourcing project fails, both customer and service provider are quick to put the blame on the other party. But in most cases, the actual culprit was really just sitting there since day one – a poorly planned and implemented agreement.

We understand how costly and disruptive a failed outsourcing project can be for your business. That is why we put utmost attention to each contract and SLA (Service Level Agreement) that our customers enter into. This always reduces the likelihood of having unmet expectations, one of the major reasons why some outsourcing relationships fail.

We make sure that each agreement is fair, not only for our customers but also for the service providers themselves. Why? Because a disadvantaged provider will most likely end up delivering poor service as an offshoot of efforts to improve its profitability and ROI.

To accomplish this, we’ll thoroughly assess the infrastructure, resources, and expertise of your potential service provider to ensure they have the capability to meet your expectations. We’ll also make sure that their expectations are realistic and clear to you as well.

Here’s what you can expect from us when we start managing your outsourcing contracts and agreements:

  • A thorough assessment of your specific needs and the service provider’s profile to determine whether you have the right match before proceeding with any agreement.
  • Professional assistance when the time comes for you to discuss the scope of work, expected service levels, and when negotiating for appropriate pricing. We’ll also help you set up provisions for possible changes in the scope later on.
  • Expert counsel during drafting and finalisation of the contract and Service Level Agreements. Whenever applicable, we’ll help you propose penalties whenever service levels are not met and rewards when they are exceeded.
  • Regular reviews to determine whether everything agreed upon in the past, like pricing and service levels, are still realistic or competitive enough in view of current technological advancements and the prevailing social and economic environment.
  • Mediation expertise whenever the outsourcing project appears to be falling apart. We’ll work with you and the service provider to resolve conflicts and avoid the expensive exercise of having to terminate the contract. But if the best solution is to part ways, we’ll make sure you make an exit with the least disruption, missed opportunities and financial loss.

Application Outsourcing

I’m sure you’ve come to realise that to gain competitive advantage these days, you really need to invest in IT applications.

There are applications for enhancing your customer relationships, speeding up production, streamlining processes, advancing collaboration, protecting your systems from malware and many more. Selecting the right application, testing it, implementing it into your system, and then managing it can deviate resources which would have otherwise been used in other areas to build business value, increase profits, and enhance innovation.

Wouldn’t it be nice to unload yourself of the management processes which usually accompany IT applications? Actually, you can – through application outsourcing. Application outsourcing providers possess the expertise to either partially or fully assume responsibility of your IT applications.

Our job is to see to it that you link up with the provider who can best answer your needs. The overall proficiency of these providers spans both proprietary and opensource solutions, allowing them to cater to a wide range of preferences and budgetary limits. At the very least, they can provide professional support for well established applications.

If needed, they can develop applications for your organisation, taking charge of every step in the system development life-cycle: starting from system initiation, requirements analysis, through design, construction, acceptance and eventually to implementation.

Here are some of the benefits you can enjoy once we start managing your application outsourcing initiatives:

  • Freedom from time-consuming tasks such as installations, upgrades, configurations and repairs.
  • Reduced total cost of ownership (TCO).
  • 24/7 support from well-trained personnel. This can substantially cut downtimes caused by inexperienced troubleshooting.
  • The option to have your applications housed in more secure and reliable environments with much higher availability and much lower planned/unplanned downtimes.
  • Dedicated specialists who can focus on providing better regulatory compliance and risk mitigation initiatives.

Infrastructure Outsourcing

Keeping up with the competition nowadays usually requires technological advancements as well as the capability to manage and maintain the infrastructure that has to support them. These undertakings can suck your resources dry.

If you’re looking to reduce costs even while improving the performance of your networks, servers, databases, firewalls, desktops and mobile devices, you might want to consider IT infrastructure outsourcing among your top options. Infrastructure outsourcing service providers have the resources dedicated to a stable, secure, scalable and always available IT infrastructure.

Typical service provider facilities include data centrers equipped with high-speed networks, reliable power, dependable security, as well as provisions for upgrades, consolidation, disaster recovery, or even business continuity.

These providers employ specialists and staff who can manage and maintain all of these for you. While your provider juggles your core IT-related tasks, you can keep your eye on the ball and refocus on your company’s business goals.

Here are some of the benefits you can enjoy out of infrastructure outsourcing:

  • Freedom from time-consuming tasks such as installations, upgrades, configurations and repairs.
  • Since service providers, who are expected to have better horizontal and vertical scalability, will deal with the technological intricacies, your company’s strategic development initiatives can proceed unhampered.
  • Greatly reduced electricity expenses as a result of consolidation.
  • Easier, faster, cheaper, and more reliable disaster-recovery solutions through virtualisation.
  • Lesser risks of disruptions caused by power outages, cyber attacks, or Internet connection downtimes.
