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.

A Definitive List of the Business Benefits of Cloud Computing

When you run a Google search for the “benefits of cloud computing”, you’ll come across a number of articles with a good list of those. However, most of them don’t go into the details, which nevertheless might still suit some readers. But if you’re looking for compelling business reasons to move your company’s IT to the cloud, a peripheral understanding of what this technology can do for you certainly won’t cut it.

Now, cloud computing is not just one of those “cool” technologies that come along every couple of years and which can only benefit a particular department.?What we’re talking about here really is a paradigm shift in computing that can transform not only entire IT infrastructures but also how we run our respective organisations.

I hate to think that some people are holding back on cloud adoption just because they haven’t fully grasped what they’re missing. That is why I decided to put together this list. I wanted to produce a list that would help top management gain a deeper understanding of the benefits of the cloud.

Cloud computing is one bandwagon you really can’t afford not to jump into. Here are ten good reasons why:

1.?Zero?CAPEX and low TCO for an enterprise-class IT infrastructure

2. Improves cash flow

3. Strengthens business continuity/disaster recovery capabilities

4. Lowers the cost of analytics

5. Drives business agility

6. Ushers in anytime, anywhere collaboration

7. Enhances information, product, and service delivery

8. Keeps entire organisation in-sync

9. ?Breathes life into innovation in IT

10. Cultivates optimal environments for development and testing

Zero CAPEX and low TCO for an enterprise-class IT infrastructure

Most cloud adopters with whom I’ve talked to cite this particular reason for gaining interest in the cloud.

Of course they had to dig deeper and consider all other factors before ultimately deciding to migrate. But the first time they heard cloud services could give them access to enterprise class IT infrastructures without requiring any upfront capital investment, they realised this was something worth exploring.

A good IT infrastructure can greatly improve both your cost-effectiveness and your capability to compete with larger companies. The more reliable, fast, highly-available, and powerful it is, the better.

But then building such an infrastructure would normally require a huge capital investment for networking equipment, servers, data storage, power supply, cooling, physical space, and others, which could run up to tens or even hundreds of thousands of euros. To acquire an asset this costly, you’d have to take in debt and be burdened by the ensuing amortisation.

If you’ve got volumes of cash stashed in your vault, cost might not be a problem. But then if you really have so much savings, wouldn’t it be more prudent to use it for other sales-generating projects? An extensive marketing endeavour perhaps?

A capital expenditure of this magnitude and nature, which normally has to be approved by shareholders, can be regarded as a high financial risk. What if business doesn’t do well and you wouldn’t need all that computing power? What if the benefits expected from the IT investment are not realised??You cannot easily convert your IT infrastructure into cash.

Remember we’re talking about a depreciating asset. So even assuming you can liquidate it, you still can’t hope to sell it at its buying price. These factors are going to play in the minds of your Board of Directors when they’re asked to decide on this CAPEX.

Incidentally, these issues don’t exist in a cloud-based solution.

A cloud solution typically follows a pay-as-you-go utility pricing model where you get billed monthly (sometimes quarterly) just like your electricity. ?In other words, it’s an expense you’ll need to pay for?at the end of a period over which the service’s value would have already been realised. Compare that with a traditional infrastructure wherein you’ll have to spend upfront but the corresponding value will still have to be delivered gradually in the succeeding months or years.

demand expense traditional infrastructure

From the point of view of your CFO, what could have been a CAPEX to acquire an asset that depreciates with time (and consequently reduces your company’s net worth), becomes a flexible operating expense (OPEX).?Truly, it is an operating expense that you can increase, decrease, or even totally discontinue, depending on what the prevailing business conditions demand.

demand expense cloud infrastructure

People who think they have done the math in comparing cloud-based and traditional IT infrastructures claim that, although they see how cloud solutions transform CAPEX into OPEX, they really don’t see any significant difference in overall costs.

However, these people have only gone as far as adding up the expected monthly expenses of a cloud solution over the estimated duration of an equivalent IT infrastructure’s effective lifespan and comparing the sum with that IT infrastructure’s price tag. You won’t get a clear comparison that way.

You need to consider all factors that contribute to the infrastructure’s Total Cost of Ownership (TCO). Once you factor in the costs of electricity, floor space, storage, and IT administrators, the economical advantages of choosing a cloud solution will be more evident. Add to that the costs of downtime such as: interruptions to business operations, technical support fees, and the need to maintain expensive IT staff who spend most of their time “firefighting”, and you’ll realise just how big the savings of cloud adopters can be.

Still not convinced? Well, we’re still getting started.?On our next post, we’ll take a closer look at the additional benefits of paying under an OPEX model instead of a CAPEX model.

Project Management

In a cutthroat market, where the competition is constantly on the attack to break into your market share, implementing a project-based system can give your organisation the necessary tools to be more efficient and agile.

However, rapidly changing consumer demands, technologies and other factors make it ever more difficult to generate a strategic advantage from projects, let alone develop one. Also since a large organisation can easily end up having to manage multiple projects at the same time, the new management paradigm can appear too complex.

What your company really needs is the expertise that can guide you starting from conception and planning, down through procurement and execution in order to maximise whatever resources you have. Each move must be well thought out so that there are clear goals and objectives as well as methods to achieve them.

Programme Management

Are you running multiple projects pointing to an overall strategic direction? Then you’ll need more than just a “scaled-up” version of project management to make sure every component’s work effort is well coordinated to achieve your enterprise’s desired outcomes.

Through our expertise in programme management, we’ll work with your stakeholders, executives and clients to achieve the following:

  • Design a well-articulated management structure and clearly define decision-making roles & responsibilities – This will ensure decisions are made rapidly with zero to minimal overlapping issues and to promote a unified, well-synchronised advance towards the common objective.
  • Set objectives then make sure they are met by guiding your key personnel in coordinating activities across projects.
  • Design or utilise existing financial models such that they adhere to your enterprise’s financial policies.
  • Develop procedures for reporting expenditures specific to the programme.
  • Establish the programme infrastructure, including
    • The appropriate technical environment and tools (e.g. hardware, software, communication, and other IT-related items)
    • IT staff and administrators
  • Evaluate your enterprise’s current IT architecture to determine whether it will suffice to achieve your objectives. If it doesn’t, propose options you can take to meet what is required.
  • Plan out activities that should take place in different levels in the organisation.
  • Implement a periodic review of the programme progress as well as of interim results to ensure everything is aligned with the strategic outcome.

Programme and Project Reviews

Whether we’ve helped you set up your programme or you did it on your own, time will come when you’ll need to know whether everything is going as planned. If it appears like the entire programme is going smoothly, chances are, something’s going awfully wrong somewhere. Remember, even the most well-planned projects and programmes are still under the mercy of unforeseen variables.

We’ve got highly specialised reviews for either projects or an entire programme. We’ll be able to provide you answers to questions like:

  • Are all projects aligned with the programme’s intended direction?
  • Are the people working on your projects as focused with the business rationale as they have been with meeting deadlines and utilising resources?
  • Where are your risks and exposures? How can they be remedied?
  • Is the project viable at all?

We understand how your staff would want to function normally as quickly as possible. Rest assured, our programme and project reviews are conducted swiftly and efficiently so that both interruptions and oversights are brought to a minimum.

After we’re done, you can expect a detailed quantitative assessment of your programme and/or projects’ status.

Basically, we’re not here to find mistakes; we’re here to help you find ways to correct them. If a project rescue is required, we’ll be the first to lend a hand.

Project Rescue

Believe it or not, many of our clients approached us not before or during their project’s planning stages. But rather, after having gone through sloppy execution, when they end up losing control. In other words, we’re usually at the receiving end of the distress signal, after they’ve punched the panic button.

While obviously this isn’t the ideal time to seek the aid of any expert because it means you’ve incurred unnecessary losses already, all is not yet lost. If the appropriate remedial actions are taken in a timely manner, you can still achieve highly acceptable end results.

In fact, in most of our experiences with project rescue operations, we’ve been able to put projects back on track – just the way the planners wanted them to be. We’ll also help you devise airtight strategies to prevent your project from going astray again.

At the end of our project rescue,

  • You’ll regain complete control
  • Milestones will be reached as planned
  • Requirements will be accomplished, and
  • The project will be realigned with ideal business directions

Project Governance Processes

Constructing a firm underlying structure is essential in any organisation. So before we’ll institute project management, we’ll do the following first.

  • Set up a PMO or Project Management Office to ensure, among others, that
    • Utilisation of facilities, budgets, technical support and other resources will be well coordinated
    • Work products can be tracked and reviewed
    • Issues regarding methodology and processes will be given appropriate attention
    • Training can be organised
    • Project management discipline be instilled in the IT department
  • Establish a steering committee to oversee the implementation of IT and business strategies
  • Fill up slots for a project manager, IT executive and a business sponsor and define the roles of each
  • Infuse project management practices to all affected units of the enterprise

Establishing PMOs, steering committees and other management structures is the easy part. Many organisations spend so much in order to create the structures related to project management, only to find out later that the effort has been all for naught. That’s why we won’t end there. Our objectives will therefore include the following:

  • To plant and cultivate an environment appreciative of project governance i.e. one that does not project it as just a bunch of bureaucratic processes and protocols.
  • To establish an organisational culture that starts at the top.
  • To make everyone involved understand that the power of project governance still lies in the hands of those who will ultimately implement it.

A project-driven enterprise is never propelled by a single project. Since multiple projects require a more complex governing structure, you’ll need to understand the intricacies of programme management.

Authentication and Access Control

Threats to your data can come from external or internal sources.

  1. There are individuals who don’t have the authorisation but are driven by malicious intentions to gain access to certain information. This may refer to individuals who already belong to your organisation (but don’t have the necessary access rights) as well as those who don’t.
  2. There are individuals who have both the authorisation and, unfortunately, the malicious intentions over certain information.
  3. Finally, there are individuals who have the authorisation, no malicious intentions, but have accidentally exposed the information in question to those without the proper authority.

While curbing threats 2 and 3 would require other methods, threat #1 can be countered if the right authentication and access control systems are in place.

Here’s what we can do for you:

  • Work with your key personnel to determine who gets access to what.
  • Help you decide whether a single factor or a two-factor authentication (2FA) is appropriate for your organisation and recommend which factors are most suitable. Login methods may include but are not limited to the following:
    • biometric devices
    • Kerberos tickets
    • mobile phones
    • passwords
    • PKI certificates
    • proximity cards
    • smart cards
    • tokens
  • Install the necessary infrastructure needed for the factors chosen. For instance, if you opt to use biometrics, then biometric scanners will be installed. We’ll make sure that the authentication terminals are situated in places where achieving optimal traffic and work flow has been taken into consideration.

Other defences we’re capable of putting up include:
