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.

Can you do away with the Project Initiation Meeting?

Project initiation meetings are often skipped to fast-track projects. Once a sponsor is found, organisations go straight to project planning and execution. But based on our own experience, holding a project initiation meeting can actually eliminate many issues that may crop up in the future and hence may speed things up instead in the long run.

It is in the project initiation meeting where your project objectives and scope are clarified and all stakeholders are brought to the same page. Project sponsors and stakeholders will have to know in a nutshell what is needed from them, what the possible risks are, what different resources are required, and so on. So that, when it’s time to proceed to the next phase, everyone is already in-sync.

So what are taken up in such a meeting? Perhaps an actual example can help. Sometime in the past, we set out to work on an eCommerce website project. After conducting the project initiation meeting, these were some of the things we were able to accomplish:

  • Identified deliverables e.g. site design, interface to payment system, etc.
  • Come up with the project phases
  • Agreed what should be in and out of scope
  • Defined the acceptance test criteria
  • Identified possible risks
  • Identified the possible training and documentation work needed
  • Established whether any analysis was required, e.g. as with regards to payment interfaces
  • Formulated disaster recovery plans
  • Defined roles and responsibilities
  • Drafted timelines and due dates

Aren’t these covered in project planning? If the project is a big one, the answer is no. In a large project, project planning is a much more exhaustive activity. In a project initiation meeting, only the basic framework is defined.

Some questions may still remain unanswered after a project initiation meeting, but at least you already know what answers you need to look for. In the example we gave earlier, we left the meeting knowing that we needed:

  • a list of all necessary hardware to estimate the costs
  • to identify possible dependencies we might have with third parties
  • to identify what software had to be bought and what skills we needed to hire

When it was time to proceed to project planning, everyone involved already knew what direction we were taking. In effect, by not skipping the project initiation meeting, we were able to avoid many potential obstacles.

Is Your Project Agile, a Scrum or a Kanban?

Few projects pan out the way we expect when starting out. This is normal in any creative planning phase. We half suspect the ones that follow a straight line are the exceptions to the rule. Urban legend has it; Edison made a thousand prototypes before his first bulb lit up, and then went on to comment, ?genius is 1% inspiration, 99% perspiration?. Later, he added that many of life’s failures are people who did not realise just how close they were to success when they gave up.

So be it to this day, and so be it with project planning too. There is no one size fits all approach when it comes to it. Agile, Scrum and Kanban each have their supporters and places where they do well. Project planning often works best when we use a sequential combination of them, appropriate to what is currently happening on the ground.

Of the three, Agile is by far the most comprehensive. It provides a structure that begins with project vision / conceptualisation, and goes as far as celebration when the job is over, and retrospective discussion afterwards. However, the emphasis on daily planning meetings may dent freethinking, and even smother it.

Scrum on the other hand says ?forget all that bureaucracy?. There is a job to do and today is the day we are going to do it. Although the core Agile teamwork is still there it ignores macro project planning, and could not be bothered with staying in touch with customers. If using Scrum, it is best to give those jobs to someone else.

The joker in the pack is Kanban, It believes that rules are there to substitute for thought, and that true progress only comes from responsible freedom. It belongs in mature organisations that have passed through Scrum and Agile phases and have embarked on a voyage towards perfection.

That said, there can be no substitute for human leadership, especially when defined as the social influence that binds the efforts of others towards a single task.

What is Servitisation?

In the current generation, innovation has transformed industries, businesses, economies, and livelihoods. Those who’ve accepted to embrace the changes have prospered and remained afloat and relevant in their respective industries.?

However, failure to embrace change has seen companies like Blockbuster pushed out of business by more innovative and technology-oriented companies like Netflix.?

What does this tell you?

That the only way to stay in business, despite the many challenges your business could be facing, is to remain alert to the dynamic demands of customers, many of which are dictated by technological advancements.?

So, if you’re a manufacturer and you’re keen on diving deeper into technology to stay on top of the game and beat your competition, you must also be expectant of the fast-approaching servitisation-centred economy. Companies like Rolls Royce that have already embraced servitisation are making great gains in their areas of expertise.?

What is Servitisation?

Servitisation can be defined as the transformation of a manufacturing firm from the mere offering of products to the market to providing innovative and invaluable services alongside their products. By so doing, the sale becomes an ongoing engagement and not a one-off event. Cranfield University professors call it “the innovation of an organisation’s capabilities and processes to better create mutual value through a shift from selling a product to selling product-service systems.”?

As foreign as it may seem for some professionals, servitisation has been a need that, though not embraced, its demand remains evident. Nonetheless, firms have hesitated to implement it. Shifting from manufacturing products only to incorporating product-centric services alongside the products is not a walk in the park. It boils down to completely changing the company’s entire structure and processes.

All the same, change is never comfortable, and that’s why it’s always best to focus on the positive for motivation.

Servitisation Case Study

Some manufacturing firms have already embraced servitisation, and they’re reaping big from it. They’ve understood the benefits of offering more value to customers at less cost. What Rolls Royce is doing currently with its “power-by-the-hour” program is a good example of servitisation.

Instead of selling Aero Engines and letting customers take charge of maintenance and uptime, Rolls-Royce now offers a full package that includes a product and relevant services.?

Essentially, what the company is creating is an intimate and long-term relationship with its customers.

The total care package by Rolls Royce means it’s essentially renting out its engines to customers and monitoring data for potential maintenance needs. The plan guarantees that maintenance is only done when necessary and avoidable damage detected in good time. As a result, there is a clear reduction in the overall cost.

Initially, Rolls Royce would make money by basically selling and repairing engines. That meant that the worse the engines, the more repairs required and the more the money the company would make.?

However, things changed when the company realised there is no demand for a product that’s constantly in the repair shop. That prompted Rolls Royce to embrace servitisation.

Servitisation aligns the interests of the customer and those of the manufacturer to ensure everyone benefits. Rolls Royce has been offering this package to airlines since 2010, and the company has seen significant returns as a result.

Benefits

There are several benefits of incorporating servitisation into your manufacturing firm. Below are three of the strongest benefits

  • Financial Stability– Servitisation establishes a more secure revenue stream because of the long term connection between manufacturer and customer. This also translates to loyal customers, meaning more profit.
  • Strong Customer Retention Rate– Being more experienced about the equipment and the constant tracking and monitoring that comes with servitisation; manufacturers are realising that they can keep more customers.
  • Selling a Solution And a Product– Today customers are not just looking to buy a product, instead, they want both the product and the solution to their problem. Meaning you make more money for the product you manufacture and the service you offer to your customers.

Implementation of Servitisation in the Industry

To effectively implement servitisation, there must be an effective two-way flow of information and data in the supply chain. Meaning you may require software like FieldElite for scalable condition monitoring of performance. With FieldElite, for example, servitisation is made easier for you because it enables you to monitor the performance of your assets remotely.

Maintenance and monitoring of assets were traditionally very expensive and time-consuming until the arrival of intelligent software that makes work easier and cost-effective for manufacturers. FieldElite uses advanced learning algorithms to remotely automate the entire process, allowing you to detect, in real-time, the performance and need for maintenance on your asset.

Required Organisational Changes

A few important steps include;

Companies that invest in continuous training and development always have a more competitive edge than their counterparts. Meaning an important step towards servitisation is training the workforce. This is important, considering that the company structure, focus, and process will have to change.

Set up a team that is focused on the challenge, change, and creation. With this, you can easily adjust to industry changes. The team should always work on knowing what should be adjusted and when it should be.?

In the shift to servitisation, adopting a comprehensive service technology is an important step. Such service technology software includes FieldElite. This technology will ensure that you’re able to monitor your product in real-time, meaning you can maintain good performance for as long as possible.

Because servitisation essentially focuses on the customer, take time to study customer behaviour. Knowing what your customers need and want will help you remain relevant in the industry.

Conclusion

As the demand for more benefits and long-lasting relationships with dealers grow, so is the need for manufacturers to adjust. Hence more and more manufacturing companies are leaning towards embracing servitisation as a solution to the growing demand.?

In turn, manufacturers who’re attaching service contracts to their product sales are making more than those who remain stuck in the traditional approach to sales.?

Essentially, servitisation will ensure that, as a manufacturer, you remain relevant to your customers now and in years to come. This is a much better arrangement in terms of saving costs and making more returns. Remember to be successful, you have to be flexible enough to change with demand.
