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.

Making Click-and-Collect click

In my previous post, I introduced you to integrated e-commerce and explained why it is the right way to extend your business online. If you already have a brick-and-mortar retailing business and you’re looking to improve your online presence, you could start offering a click-and-collect service.

With click-and-collect, customers order online and then collect their merchandise from one of the retailer?s local branches. Why would they want to do that?

Apparently, there are buyers who now prefer a click-and-collect service over the delivery service of a purely online retailer. With the latter, they sometimes have to wait forever for the delivery van to arrive or contend with a missed-delivery card.

Basically, customers who want both the convenience of placing orders online and better control of their time find click-and-collect a better option.

Last December 2011, IMRG (Interactive Media in Retail Group) reported a ?significant rise in the percentage of click-and-collect e-retail sales in the 3rd quarter of 2011?. This accounted for 10.4% of all e-retail sales in that quarter. More specifically, the gain was 7.4%, which was also the strongest quarterly gain since IMRG started collecting this data.

Clearly, this particular service is gaining popularity. But how do you meet the rising demand in this area?

A click-and-collect service requires a highly synchronised ecosystem. You don’t want to have a customer order items from your online store, drive a couple of minutes from his house to your nearest outlet, only to find out that one of the items is no longer available.

This can only work if all systems involved are interconnected. Changes in the inventory in your individual outlets should reflect on your database in real time. In turn, these changes have to be reflected instantly on your online store. Conversely, once a buyer has picked items online and is already directed to a local outlet, those items have to be reserved there.

But that’s not all. Your system has to be seamless enough to support fast and reliable service. You don’t want your buyer to have to wait a long time before the items are ready for pick-up. It also has to be capable of tracking the status of ordered products, handling uncollected orders, and monitoring inventory.

By implementing an integrated e-commerce system, these won’t be the only things you?d be able to do. You can even add more value to your service. For example, you can connect to your CRM and learn more about your customers? purchase history, buying habits, and preferences.

That way, it would be easier for you to provide a faster and more convenient buying experience for them in the future.

Click-and-collect is a very promising way to increase your sales and improve customer loyalty.

Saving Energy Step 2 ? More Practical Ideas

In my previous blog, we wrote about implementing a management system. This boils down to sharing a common vision up and down and across the organisation, measuring progress, and pinning accountability on individuals. This time, we would like to talk about simple things that organisations can do to shrink their carbon footprints. But first let’s talk about the things that hold us back.

When we take on new clients we sometimes find that they are baffled by what I call energy industry-speak. We blame this partly on government. We understand they need clear definitions in their regulations. It’s just a pity they don’t use ordinary English when they put their ideas across in public forums.

Consultants sometimes seem to take advantage of these terms, when they roll words like audit, assessment, diagnostic, examination, survey and review across their pages. Dare we suggest they are trying to confuse with jargon? We created ecoVaro to demystify the energy business. Our goal is to convert data into formats business people understand. As promised, here are five easy things your staff could do without even going off on training.

  1. Right-size equipment? outsource peak production in busy periods, rather than wasting energy on a system that is running at half capacity mostly.
  2. Re-Install equipment to OEM specifications ? individual pieces of equipment need accurate interfacing with larger systems, to ensure that every ounce of energy delivers on its promise.
  3. Maintain to specification ? make sure machine tools are within limits, and that equipment is well-lubricated, optimally adjusted and running smoothly.
  4. Adjust HVAC to demand ? Engineers design heating and ventilation systems to cope with maximum requirements, and not all are set up to adapt to quieter periods. Try turning off a few units and see what happens.
  5. Recover Heat ? Heat around machines is energy wasted. Find creative ways to recycle it. If you can’t, then insulate the equipment from the rest of the work space, and spend less money cooling the place down.

Well that wasn’t rocket science, was it? There are many more things that we can do to streamline energy use, and coax our profits up. This is as true in a factory as in the office and at home. The power we use is largely non-renewable. Small savings help, and banknotes pile up quickly.

The Matrix Management Structure

Organizations exploit matrix management in various ways. A company, for instance, that operates globally uses it at larger scale by giving consistent products to various countries internationally. A business entity, having many products, does not assign its people to each product full-time but assign those to different ones on a part time basis, instead. And when it comes to delivering high quality and low cost products, companies overcome industry pressures with the help of many overseeing managers. In a rapidly changing environment, organizations respond quickly by sharing information through a matrix model.

Understanding the Matrix Management Structure

A basic understanding of matrix management starts with the three key roles and responsibilities that applies in the structure.

  • Matrix Leader ? The common person above all the matrix bosses is the matrix leader. He ensures that the balance of power is maintained in the entire organization by delegating decisions and promoting collaboration among the people.
  • Matrix Managers ? The managers cooperate with each other by defining the respective activities that they are responsible for.
  • Matrix Employees – The employees have lesser direct authority but has more responsibilities. They resolve differing demands from more than one matrix managers while they work things out upwards. Their loyalty must be dual and their relationships with managers must be maintained.

Characteristics of a Matrix Structure

Here are some features that define the matrix management structure:

  • Hybrid Structure ?The matrix structure is a mix of functional and project organization. Since it is a combination of these two, matrix management is hybrid in nature.
  • Functional Manager ? When it comes to the technical phases of the project, the functional manager assumes responsibility. The manager decides on how to get the project done, delegates the tasks to the subordinates and oversees the operational parts of the organization.
  • Project Manager ? The project manager has full authority in the administrative phases, including the physical and financial resources needed to complete the project. The responsibilities of a project manager comprise deciding on what to do, scheduling the work, coordinating the activities to diverse functions and evaluating over-all project performance.
  • Specialization ?As the functional managers concentrate on the technical factors, the project managers focus on administrative ones. Thus, in matrix management, there is specialization.
  • Challenge in Unity of Command ? Companies that employs matrix management usually experience a problem when it comes to the unity of command. This is largely due to the conflicting orders from the functional and project managers.

Types of Matrix Structure

The matrix management structure can be classified according to the level of power of the project manager. Here are three distinct types of matrix structures that are widely used by organizations.

  • Weak Matrix ? The project manager has limited authority and power as the functional manager controls the budget of the project. His role is only part-time and more like a coordinator.
  • Strong Matrix ? Here, the project manager has almost all the authority and power. He controls the budget, holds the full time administrative project management and has a full time role.
  • Balanced Matrix ? In this structure type, both the project and functional managers control the budget of the project. The authority and power is shared by the two as well. Although the project manager has a full time role, he only has a part time authority for the administrative staff to report under his leadership.

Successful companies of today venture more on enhancing the abilities, skills, behavior and performances of their managers than the pursuit of finding the best physical structure. Indeed, learning the fundamentals of the matrix structure is essential to maximize its efficiency. A senior executive pointed out that one of the challenges in matrix management is not more of building a structure but in creating the matrix to the mind of the managers. This comes to say that matrix management is not just about the structure, it is a frame in the mind.
