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.

Field service and its impact on your bottom line

There are many pointers to successful field service in any business. Generally, labour hours, parts, technician efficiency, performance indicators and other bunch of data are the most important. However, the icing on top is the total revenue. If you are in business, you must be cocksure that it’s making money, and when you don’t rake in enough you need to make some business decisions quick!

For the most part, field service companies will always have a field service management software to handle all the data. But how will this affect your outlook?

Will this cause a direct increase in revenue?

What will still need to be changed so that the ship stays afloat?

Increase your service jobs

As expected, the best field management software will guarantee a positive increase in appointments per week. On average, the field service team should expect at least a 50% increase in work turnover. There is a direct relation between the revenue you should be making and the number of calls in your schedule since the only way of making more cash is to get more work done. It is not recommended to raise costs because it increases the risk of losing customers easy when they can’t meet the extra expense. Field service software will help you bring in more customers and also manage technicians.

If you have much of the hard work done for you then you?d have more time to run the show. This is why premises are trying out software because they answer many problems like:

Automation and improved work order management
Fast dispatch from an array of drag-drop scheduling tools
Easy-to-use field service apps for technicians to receive and submit work orders
Can be integrated into account systems for faster billing time

Manual operations are costly and prone to error, and they don’t come cheap. Do away with them, reduce costs, sit back and watch as new customers steadily stream in. Grow the business by building lasting relations with your workforce and customers.

Increase technician?s abilities with mobile

If you want to get more profit, bank on technicians who complete service calls. Their task is obviously the hardest. They have an unpredictable job; at times they need to come up with quick responses or they may also be required to dig deep as well. The work does not need to be slowed with an endless paper trail while they could be elsewhere giving their all. These technicians require a working mobile field service management app.

As expected, field service leaders who use a mobile field service software report close to 20% increase in service visits per technician. This translates to each technician taking nearly a fifth more calls in a day. And as we had said before, more service calls can double the profits. How can technicians get extra time from a field service mobile app?

No need to drive to work to pick orders
Less time using the phone looking for service or parts information
Reduces the time needed to go through paper-based work
Less time driving to service calls because information is routed to their mobile phones

Increase revenue from technicians

If time is spent seamlessly, dispatchers will find time in a technician?s schedule for an extra service call. With all this being done within normal working hours, the business stands to increase its bottom line. This is what makes the business grow. Not by increasing technicians but by optimum utilisation of the current staff to get maximum profit. The logic is straightforward ? a technician working 8 hours each day taking six calls a day will make more revenue than the one who takes four, because they are paid the same each, but the business benefits from the extra service calls.

The business stands to make more revenue per technician if it uses field service management software. The margins can go as high as 40% because the technician has all tools needed to get the job done faster. You increase revenue from field work too. Let technicians benefit from automated process and have all the tools for work that they need right on their mobile devices.

The target is always your bottom line

When field service leaders inquire about field service software, they need to know how it affect the bottom line: how they will spend less time drafting schedules, how each technician will increase revenue, how the business will grow. Simple as that!
Field service management applications bring a lot to the table.

Don’t waste your time crunching a lot of numbers or sorting out schedules since this is what such an application should do. Automation, optimisation and mobility are all ways of increasing revenue. Let us help you reach your goals using our top shelf field management software. This will not only help your bottom line but will let you have more time to venture into untapped potentials.

Data Replication

These days, not many companies can continue to operate once their entire computer system goes down. All the information needed in daily operations are stored in databases while the interfaces that make use of them all come in the form of software applications.

Software applications can be rapidly reinstalled and configured for as long as the necessary programs are available. Data, however, cannot be reconstructed as quickly even with hard copies available. It is therefore necessary to store your data in a replicated setup so that when one section goes down, operations can proceed without interruption.

For instance, if a category 5 hurricane renders your main office useless, you can simply rent workstations elsewhere, connect to the Internet and continue with your usual transactions for as long as data is readily accessible.

So how do we ensure the accessibility and reliability of your data? Here’s what we’ll do:

Activate data replication on your database management system. If your DBMS does not support replication, we’ll migrate all your data to one that does.
If absolutely necessary, we can allow modernised systems to run parallel to your legacy systems and prepare both for full modernisation when you’re ready.
Implement fail-over technologies where applicable to provide for automatic switching to a backup data server or network from one that has just failed.

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 CO₂to 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.
