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.

Will UK Retailers Skim the Cream with ESOS?

The British Retail Consortium (BRC) was quick out on the starting blocks with an ambitious plan to cut energy costs by 25% in 5 years. Their ?25-in-5? initiative is chasing a target of ?4.4 billion savings during the duration. Part of this program involves ?cutting a path through a complex and inaccessible policy landscape?. BRC believes this drawback is making its members think twice about making energy efficiency investments.

The UK?s sprawling network of grocers, department stores and malls is the nation?s second most hungry energy customer, having spent ?3.3 billion on it in 2013 when it accounted for almost 20% of carbon released. If you think that sounds bad, it purchased double that amount in 2005. However the consortium believes there is still more to come.

It bases this assumption on the push effect of UK energy rates increasing by a quarter during the duration of the project. ?So it makes sense to be investing in energy efficiency rather than paying bills,? Andrew Bolitho (property, energy, and transport policy adviser) told Business Green. The numbers mentioned exclude third party transport and distribution networks not under the British Retail Consortium umbrella.

The ?complex and inaccessible policy landscape? is the reflection of UK legislators not tidying up as they go along. BRC cites a ?vast number of policies ? spreading confusion, undermining investment and making it harder to raise capital?. The prime culprits are Britain?s CRC Energy Efficient Scheme (previously Carbon Reduction Commitment) which publishes league tables and ESOS. Andrew Bolitho believes this duality is driving confused investors away.

The British Retail Consortium is at pains to point out that this is not about watering things down, but making it simpler for participating companies to report on energy matters at a single point. It will soon go live with its own information hub providing information for retailers wishing to measure consumption at critical points, assemble the bigger picture and implement best practice.

Ecovaro agrees with Andrew Bolitho that lowering energy demand and cutting carbon is not just about technology. We can do much in terms of changing attitudes and providing refresher training and this does not have to cost that much. Studies have shown repeatedly that there is huge benefit in inviting employees to cross over to our side. In fact, they may already be on board to an extent that may surprise.

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.

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:

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.

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.

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:

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.

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.

Succeed at Transformation

Despite the pomp and fanfare associated with launching corporate transformation programs, in reality very few of them succeed. According to a recent report by McKinsey the success rate is pegged below 40%. In addition, the same research indicates that defensive transformations – those undertaken as part of crisis management – have lower chances of success than progressive ones – those launched to streamline operations and foster growth. However, adopting certain strategies, like setting clear and high goals, and maintaining energy and engagement throughout the implementation phase, can really boost the project’s success rate. A key aspect of business transformation is IT transformation. This can be attributed to the fact that significant business change is either driven or influenced by technological change.

So what is IT Transformation?

IT transformation is basically a holistic reorganisation of the existing technological infrastructure that supports the company’s mission critical functions. In essence, IT transformation is not all about effecting change for the sake of change but involves systematic steps that align IT systems to business functions. To appreciate this approach, it is important to explore current trends in the business world where human resource, finance and IT transformations are being carried out in unison. This is being done to develop strong corporate centres that are leaner, agile and more productive that enhance greater synergies across all business functions.

IT transformation inevitably results in major changes of the information system’s technology, involving both hardware and software components of the system, the architecture of the system, the manner in which data is structured or accessed, IT control and command governance, and the components supporting the system. From this scope of works it is evident that IT transformation is a huge project that requires proper planning and implementation in order to succeed.

Tips to Improve Success in IT transformations Projects

1. Focus on Benefits not Functionality

The project plan should be more focused on benefits that can be accrued if the system is implemented successfully rather than system functionality. The benefits should be in line with business goals, for instance cost reduction and value addition. The emphasis should be on the envisaged benefits which are defined and outlined during the project authorisation. The business benefits outlined should be clear, feasible, compelling and quantifiable. Measures should be put in place to ensure that the benefits are clearly linked to the new system functionality.

2. Adopt a Multiple Release Approach

Typically most IT projects are planned with focus on a big launch date set in years to come. This approach is highly favoured because it simplifies stakeholder expectation management and avoids the complexity associated with multiple incremental releases. However, this approach misses the benefit of getting early critical feedback on functioning of the system. In addition, the long lead times often result in changes in project scope and loss of critical team members and stakeholders. IT transformation projects should be planned to deliver discrete portions of functionality in several releases. The benefit of multiple release approach is that it reduces project risks and most importantly allows earlier lessons learnt to be incorporated in future releases.

3. Capacity of the Organisation to confront Change

As pointed out, IT transformations result in significant changes in business operations and functions. Hence it is important that all business stakeholders should be reading from the same script in regards to changes expected. In addition, key stakeholders should be involved in crucial project stages and their feedback incorporated to ensure that the system is not only functional but business focused.
