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.

Job & Staff Scheduling with FieldElite Mobile Service Management Software

Field Service Management (FSM) software systems are designed to enable you to manage your mobile workforce from a central point- and do away with the paperwork involved with the process. They connect your technicians on the ground (via app on their phones), to the staff at the head office- who have an interactive dashboard accessed through their browsers. The office team will have access to all the jobs that are to be handled by the company, simplifying the management process and taking away the risks that come with manual data entry. Here, we will walk you through a quick process of scheduling a job for your personnel with FieldElite.

Say you are a HVAC contractor, licensed, bonded and insured. You’ve made quite a name for yourself in the industry, and have a wide range of clients- in both residential and commercial establishments. Consequently, you also have a large workforce to attend to the different situations- from installing to repair and maintenance. One of your clients- let’s call them ABC Computer Supplies, has an issue with their HVAC unit- perhaps a pipe is leaking. It needs to be fixed, and ABC have booked an appointment.? Your goal here is to get one of your personnel to handle the task as soon as possible, and this field service scheduling software comes in handy.

There are two approaches that you can take:

1. Job Scheduling

From your Dashboard, on the left-hand side you will see the menu option. Clicking on Jobs, will take you to all jobs carried out by your company.

FieldElite

The filters will allow you to view different categories of jobs:

  • Complaint– This means that there was an issue with on ground during the task delivery, and the client lodged a complaint.
  • On hold– Here, different aspects can cause a job to be paused- like when spare parts or equipment required for repair jobs have been ordered, and one needs to wait for them to be shipped in from a different location.
  • Pending– This is basically your in-tray, a list of jobs that are to be carried out.
  • In Progress– The technicians are on the ground, attending to the client’s needs, and you’re getting routine updates from them.
  • Incomplete– Though the job had been assigned to the required technician, it was not completed in the set amount of time, thus requiring an additional visit to the site. Given that the FSM solution increases the first-time fix rate, cases of ?incomplete tasks? are reduced.
  • Complete– The task is successfully done and the customer has appended their e-signature, and now it can be invoiced.
  • Cancelled Invoice– The head office determines that a particular invoice shouldn’t be paid, and thus cancels it.

Our focus here is the pending tasks, so use this filter. ABC’s HVAC job will be among these. Clicking on its Job ID will open up the details of the task, with such an Update Job window:

FieldElite Job

This section contains all the information of the job- both past and present, which you can update in real-time. Any changes will be recorded by the system and can be viewed on the “Audit” tab.

As you can see here, the HVAC repair job is both “pending” and “urgent”. No one really likes sitting in an office that feels like an oven. Being the headquarters, it’s likely handles lots of foot traffic, and the damaged HVAC unit will make the working conditions really difficult. It’s best not to keep the client waiting, right?

So, head on over to the Supervisor and Workers section (on the same “Details” tab), and select the personnel suited for the task.

FieldElite Job Details

Set the time that the task will take for your technician, and once satisfied with the details of the job, click on Update. Voila! You’re done.

FieldElite Job Update

Immediately this happens, the worker received a notification on their app, telling them that they have been assigned the job.

From the app, the technician will be able to view the specifics of the HVAC job, including notes and attachments that you can add directly from your own dashboard, such as schematics of the building and reports from other technicians who installed the air conditioning system for the facility. You also get to add products that will be required for the task- like the pipe and panel mounted socket shown here. As the system also includes an inventory of the products used, their quantity and costs, you will be able to keep an accurate record of the supplies as they as are used.

As such, the field workers will not have to keep coming back to the central office to get documents and reports of new tasks, or walk around with bulky files. When they are carrying out the job, they will also be able to keep the staff at the office updated about its progress, through the chat feature on the mobile app, taking photos and adding notes as required.

2. Staff Scheduling

With this approach, the perspective is basically: ?So I have a couple of jobs- which of my employees has time to handle them?? The FSM allows you to optimise your productivity- by ensuring that you get the most out of the staff work hours, and avoid cases of jobs going into overtime.

Follow these steps:

  1. Select ?Scheduler? from the left-hand side of the window. You will have a view of the workers of your company and how their day is planned out, and a summary of the unassigned jobs.

Here, you can tell whose busy, and who can have a new task assigned to them at the click of a button- which is far more effective than keeping on jotting down points in your diary or going through files of documents.

If the job has yet to be added to the system- like for the cases of new clients, simply click on the ?Add Job? button and key in its details.

2. Scroll down, you will see a list of unassigned jobs.

unassigned jobs

3. Next, click on the edit button under ?Actions?. This will take you to the same ?Update Job? window described in the first approach, in order to assign the preferred worker to the role.

This real-time dispatching avoids cases of your desk getting cluttered with paper sheets, and prevents duplicate entries as each job has its own ID and task details- from the scheduling to the invoicing. In this case, your HVAC technician will have access to the information needed right at the palm of their hand, to ensure that the task at ABC?s head office goes seamlessly. The optimised schedule will enable the task to be carried out faster- restoring normalcy to your client’s facility.? In case the client’s location is on the route that one of your technicians takes while heading home, you can take advantage of this by giving them the task towards the end of their working day- thus clearing more of your backlog, sorting out your client, and easing your technician?s worries about getting home late.

As you can see, the field service scheduling software enables you to easily and efficiently handle your workflow, avoid the mess that is associated with manual documentation and cases of your employees getting conflicting schedules and overlaps- which would strain them and dampen their morale. Streamlining your workflow and standardising operations ultimately results in increased customer satisfaction.

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 CO2 to 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.

The Child at Work: Fun Team Builds with LEGO SERIOUS PLAY

There is a child just below the surface in all of us. When were kids, adults lopped off the sharp bits that intruded into their ?genteel? society. Schools, to their everlasting shame sanded away our unique free spirits, as they stuck us into uniforms and imposed a daily classroom discipline. We received badges and prizes if we obeyed, and strict sanctions when we did not. This produced a generation of middle-age managers who no longer know how to play.

Life can be so deadly serious ?

Things work pretty much the same in business. Life is deadly serious. If we want to keep our jobs, we must deliver on the bottom line in our departments. There is little time for fun outside the Christmas party, when we may, within the limits of decorum engage in activity for enjoyment and recreation, rather than a serious or practical purpose.

Team builds (and strategic planning sessions) can be deadly boring affairs that proceed down narrow funnels defined by human resource facilitators. No matter how hard HR they may try, the structural hierarchy will remain intact, unless they find a way to set it aside during the program. Injecting fun into the occasion liberates independent thought, and this is why.

? But not for a little child at play

Next time you dine out at a branded family restaurant, select a seat that allows you observe the kiddies? play zone. Notice how inventive children become, when the family hierarchy is not there to tell them what to do (although parents may try from the wrong side of the soundproof glass). The ?serious play? side of fun team-builds aims to liberate managers by releasing their child for the duration. Shall we dig a little deeper into this and discover the dynamics?

Many of us have less than perfect oral communication skills. This is one of the great impediments to modern business meetings. We may not have sufficient time to formulate our thoughts for them to remain relevant when we speak. When we express them, we sense the group?s impatience for us to hurry up, so other members can have their opportunity to contribute.

Sharing better thinking with LEGO? bricks

Most of us feel an urge to click the brightly coloured plastic bricks together that carpenter Ole Kirk Christiansen released into a war-weary world in 1949. The basic kit is a great leveller because the blocks are all the same, and the discriminators are the colours and the power of our imagination. Watching a free-form LEGO builder in action is equally fascinating, as we wonder ?what they will do next? and ?what is happening in their mind.?

Examples of LEGO Serious PLAY in action

Instead of asking team members to describe themselves in a minute, a LEGO? SERIOUS PLAY? facilitator may gather them around a table piled high with LEGO bricks instead, and ask them to each build a model of themselves. The atmosphere is informal with interaction and banter encouraged. It is still serious play though, as team members get to know each other, and their own personalities better

The system is equally effective in strategic sessions, where the facilitator provides specially selected building blocks for the team to experiment with as they learn to listen, and share. This enables them to deconstruct a problem into its component parts, and share solutions regardless of seniority, culture, and communication skills.

Creating problem- and solution-landscapes three dimensionally this way, enables open conversations that keep the focus on the problem. Participants at these team builds do not only reach effective consensus faster. They are also busy building better communication skills as they do.
