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.

Data Leakage Prevention – Protecting Sensitive Information

When DuPont lost $400 million in intellectual property, it wasn’t because a hacker from the other side of the world infiltrated their system. The information was simply stolen by a former employee. Alarmingly, data loss incidents are not always caused by deliberate actions.

A file containing personal information accidentally attached to an email and sent to multiple recipients; financial data stored in a USB pen drive, accidentally left in a restaurant; or bank account data of colleagues, inadvertently posted on a company website – these are also some of the everyday causes of data loss.

A report done by research company Infowatch regarding global data leaks in 2010 showed that there were actually more accidental data leaks in that year compared to intentional ones. Accidental leaks comprised 53%, while intentional leaks comprised 42% (the rest were unidentified).

But even if they ?only? happened accidentally, breach incidents like these can still be very costly. The tens of thousands of dollars that you could sometimes end up paying in civil penalties (as in the case when you lose other people?s personal information) can just be the beginning. More costly than this is the loss of customer and investor confidence. Once you lose those, you could consequently lose a considerable portion of your business.

Confidential information that may already be leaking out right under your nose

With all the data you collect, process, exchange, and store electronically every day, your IT system has surely now become a storehouse of sensitive information. Some of them, you may be even taking for granted.

But imagine what would happen if any of the following trade secrets fell into the wrong hands: marketing plans, confidential customer information, pricing data, product development strategies, business plans, supplier information, source codes, and employee salaries.

These are not the only kind of data that you should be worried about. You could also get into trouble if your sloppy IT security fails to protect employee or client personal information such as their names; social security numbers; drivers license numbers; or bank account numbers and credit/debit card numbers along with their corresponding PINs.

In some countries, you could face onerous data breach notification requirements and heavy fines when these kind of data are involved.

There are now more holes to plug

It’s not just the different varieties of sensitive electronic information that you have to worry about. Because these data can take on different forms, i.e. data-at-rest, data-in-motion, and data-at-the-endpoints, you also need to take aim at different areas in your IT system.

Sensitive information can be found ?at rest? in each of your employees? hard disks, in your servers, storage disks, and in off-site backup disks. They can also be found ?in motion? in email, instant messaging, social networking messaging, P2P file sharing, ftp, http, and so on.

That’s not all. Your highly mobile workforce may have already introduced yet another high-risk area into your system: data-at-the-endpoints. This includes USB flash-disks, laptops, portable hard disks, CDs, and even smartphones.

The main challenge of data leak prevention

Having been made aware of the various aspects of data leakage, have you already come to grips with the extent of the task at hand?

There are two major things you need to do here to prevent data leakage.

One, you need to identify what data you have that can be considered as sensitive/confidential information. Of course you have financial information and employee salaries in your files. But do you also store personally identifiable information? Do you have trade secrets that are stored in electronic form?

Two, you need to pinpoint their locations. Are they only on your hard disks and laptops? Or have they made their way to flash drives, CDs/DVDs, or portable HDDs? Are they being transmitted through email or any other file transfer media?

The reason why you need to know what your sensitive data are as well as where they are is because you would like all efforts of securing them to be as efficient and unobtrusive as possible.

Let’s say, as a way of protecting your data, you decide to implement encryption. Since encryption can consume a lot of storage space and significantly reduce performance, it may be impractical to encrypt your entire database or all your files. For the same reason, you wouldn’t want to encrypt every single email that you send.

Thus, the best way would be to encrypt only the data that really need encryption. But again, you need to know what data needs to be encrypted and where those data can be found. That alone is no simple task.

Not only will you need to deal with the data you already have, you will also have to worry about the data that will go through your systems during the course of your day-to-day transactions.

Identifying sensitive data as it enters or leaves your system, goes through your network, or gets stored in your file system or database, and then applying the necessary security actions should be done automatically and intelligently. Otherwise, you could end up spending on a lot of man-hours or, worse, wasting them on a lot of false positives and negatives.

Field service and improved visibility

A manager is someone who has control over a company. They are given the responsibility of overseeing what the company does and making important decisions. The manager is the most important person in the empire and needs to be in the know at all times. Not what happened a day ago but in real-time and from any place.

Information is necessary for this to happen. It needs to be concise, brief and straightforward. Ideally, access to job status, location information, customer information, notifications and location information should be on the palms of their hands.

To sum it all up, there should be fluid communication among personnel in the field. Information should be accessed easily from one place as it flows to another to maintain steady two-way communication. This is possible with automation meaning that no amount of data will be left unseen or unused because of paperwork that was never handed over or looked into, reducing the chance of misinformation or missing information to a minimum.

Ways improved visibility will help your business through Field Service

Organisations using field services will agree that improved visibility has more business benefits and the real question is what aspect needs improving rather than discussing the benefits.

Real-time visibility

Managers need to be in the know from anywhere at any time. The manager needs information about the company. The need not to be physically present to have an idea of what’s going on. They should know everything at all times, from what was planned for the day to real-time events.

All this information should be easily accessed from one central point and should contain everything about the company and other relevant information.

Extending the back office into the field

This two-way communication is virtually irreplaceable. At any time, the information should flow among technicians in the field and those in the back office. This will help to have a better idea of how to manage the workload and come up with solutions to some work-related issues.

Everyone in the team should be informed and be up to speed about real-time events. Keeping everyone updated improves visibility because they can make updates and decisions based on the kind of information they get.

No more lost paperwork

Managing paper trail can be quite a hassle for organisations. With tons of workload, there can be many delays meaning that some information might be missed or forgotten. People might also choose not to turn up for work for days on end and can affect how much info is processed. Some work can be left undone, and work not invoiced.

When organisations use field service management services, information is fed only once and everything else is done automatically. Say goodbye to lags or relying on last month?s data. Work will move faster because people will have more time to focus on important things rather than chasing an endless paper trail.

Business intelligence

Field service management technology will let you know what is being done in the field and with such an abundance of data, will make sound decisions for the business.

Every decision is hinged on cold facts. Information needs to be easily accessed and filtered into the right categories so that sound business decisions are made from the collected data.

Growing revenue

The abundance of real-time information and improved visibility can determine whether a business will grow or not. Each piece of information can show trends that are critical for any business to improve. Trends show how each sector is doing and sheds more light into specific areas that need a total overhaul. This may include improving customer service, products on retail or hiring more technicians.

Without information, a company is one step closer to going out of business. Every action should be geared to increase the revenue and this starts by making the right choices.

Visibility when working offline

Working offline is an issue that can affect visibility. Sometimes agents will need to work in areas that have little network coverage or are deep down working in tunnels or are around heavy machines and turbines. Field service solutions are built for the mobile environment and for workers who may find themselves in non-connected areas so that they can still use their device while offline. This makes sure that there is no loss of information while working in-field

Time-saving

Certainly, business is constrained to its environments and if the demand changes it should prove to be flexible enough to adjust to changes as they happen. Field service solutions operations like schedule need to update instantly. Once activities start rolling, nothing should create lags in the schedule so that operations flow seamlessly at all time.

Field workers can then make updates and document changes easily on the job site directly on their device by using responsive site menus, drastically saving time while feeding data and complete orders.

Improved customer service

It is not a clich? to say that the customer is always right. With real-time information, both field service and back-office technicians can improve customer relations and satisfaction. With a unified system of sharing information like the ERPs and CRMs, the field officer can know more about specific clients, their history and other data to know more about what should be done in current and future orders. This means that better decisions will be made for each customer.

How improved visibility benefits different parts of the organisation

Improved visibility in all areas of the business makes information more accessible. Here are some of the benefits that various sects of a business can get from improved visibility.

? The business owner
The manager owns the company and can access all information with just a single tap. A lot of data can be used to analyse the health of the venture. This includes revenue, inventory, customer surveys, employee hours, invoices and customer data.
Profitability is increased by putting more emphasis on customer satisfaction and improving the quality of end products and services.

? The service manager
The service manager can see what is going on in the field in real-time, and look into measures that can improve the productivity of staff members in various departments.
And with workflow automation, time-saving is at the maximum because there is less paperwork consequently improving scheduling and job completion rates.

? Service administrator/ dispatcher
For the team in the office, they can assign tasks faster. Scheduling is automatically done and updated in real-time. It eliminates the need for paperwork and leaves more time to be productive on other errands.

? The field technician
Improved visibility for a field worker means that they can do their best in any task. They can share or get critical information about orders and customers. This drastically improves job completion rates and customer satisfaction.

? HR
Live information can be used to track certain orders, the time it takes to complete orders, and the number of staff required in the organisation. Such data can be used in HR to reduce payroll errors and erroneous overtime costs.

? Finance
Field service management software can also benefit the finance team by automation of invoices. A work order can be tracked from start to the end and invoiced immediately to retain faster payments. Relevant data can be used to track revenue and expenditures, and costs.

Real-time visibility gives a company many solutions to manage the workload. In the end, visibility is also useful in increasing revenue and a smooth transition of information for the company.

2015 – What’s ahead for UK Business?

According to reports just in, the global environment industry is down. Less money is available for what some CEO?s still see as grudge expenditure, and many U.S. agencies are seeking soft budget cuts. The UK is proving to be an exception following the announcement of ESOS, and EcoVaro does not expect the May elections will have much impact in this regard.

ESOS calls for mandatory energy assessments in companies above a certain size, and requires specific proposals to cut consumption. There is no indication of compulsory follow-through, although it is clear the Environment Agency hopes rising electricity prices and the prospect of monetary savings will do the trick.

It is an open question whether the Tory government would have interfered with commerce to this extent, were it not for the European directive that enforced it. The overall goal is to cut EU energy consumption across the board by 20% by 2020. Energy consultants are rubbing their hands in glee. EcoVaro?s response is to provide cloud-based software.

We will be interested to see how many UK companies make the first deadline of 5 December 2015, in the light of reports that half the 9,000 firms affected appear not to even know that ESOS exists. Some will no doubt pay last-minute lip service. Those with an eye on their own sustainability will grasp the Energy Saving Opportunity Scheme with both hands.

The initial ESOS deadline was always going to be a challenge. Some big corporates have stolen a march albeit egged on by green stakeholders. The next challenge comes in June 2015 with the implementation of the European Union?s ?Waste Catalogue? of hazardous substances, and rules for their disposal. We hope a new ISO 14001 will arrive soon and pull the loose threads together.

The introduction of carbon trading late this year brings further opportunities to increase profits through wise stewardship. Auditable metrics are essential for this.
