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.

What Kanban can do for Call Centre Response Times

When a Toyota industrial engineer named Taiichi Ohno was investigating ways to optimise production material stocks in 1953, it struck him that supermarkets already had the key. Their customers purchased food and groceries on a just-in-time basis, because they trusted continuity of supply. This enabled stores to predict demand, and ensure their suppliers kept the shelves full.

The Kanban system that Taiichi Ohno implemented included a labelling system. His Kanban tickets recorded details of the factory order, the delivery destination, and the process intended for the materials. Since then, Ohno?s system has helped in many other applications, especially where customer demand may be unpredictable.

Optimising Workflow in Call Centres
Optimising workflow in call centres involves aiming to have an agent pick up an incoming call within a few rings and deal with it effectively. Were this to be the case we would truly have a just-in-time business, in which operators arrived and left their stations according to customer demand. For this to be possible, we would need to standardise performance across the call centre team. Moving optimistically in that direction we would should do these three things:

  • Make our call centre operation nimble
  • Reduce the average time to handle calls
  • Decide an average time to answer callers

When we have done that, we are in a position to apply these norms to fluctuating call frequencies, and introduce ?kanbanned? call centre operators.

Making Call Centre Operations Nimble
The best place to start is to ask the operators and support staff what they think. Back in the 1960?s Robert Townsend of Avis Cars famously said, ?ask the people ? they know where the wheels are squeaking? and that is as true as ever.

  1. Begin by asking technical support about downtime frequencies, duration, and causes. Given the cost of labour and frustrated callers, we should have the fastest and most reliable telecoms and computer equipment we can find.
  1. Then invest in training and retraining operators, and making sure the pop-up screens are valuable, valid, and useful. They cannot do their job without this information, and it must be at least as tech-savvy as their average callers are.
  1. Finally, spruce up the call centre with more than a lick of paint to awaken a sense of enthusiasm and pride. Find time for occasional team builds and fun during breaks. Tele-operators have a difficult job. Make theirs fun!

Reducing Average Time to Handle Calls
Average length of contact is probably our most important metric. We should beware of shortening this at the cost of quality of interaction. To calculate it, use this formula:

Total Work Time + Total Hold Time + Total Post Call Time

Divided By

Total Calls Handled in that Period

Share recordings of great calls that highlight how your best operators work. Encourage role-play during training sessions so people learn by doing. Publish your average call-handling time statistics. Encourage individual operators to track how they are doing against these numbers. Make sure your customer information is up to date. While they must confirm core data, limit this so your operators can get down to their job sooner.

Decide a Target Time to Answer Calls
You should know what is possible in a matter of a few weeks. Do not attempt to go too tight on this one. It is better to build in say 10% slack that you can always trim in future. Once you have decided this, you can implement your Kanban system.

Introducing Kanban in Your Call Centre Operation
Monitor your rate of incoming calls through your contact centre, and adjust your operator-demand metric on an ongoing basis. Use this to calculate your over / under demand factor. Every operator should know the value on this Kanban ticket. It will tell them whether to speed up a little, or slow down a bit so they deliver the effort the call rate demands. It will also advise the supervisor when to call up reserves.

Mobile Workforce Management in a nutshell

It is fairly common for businesses to have staff working across many different locations across the country or even the world.  Engaged in various activities like  door-to-door sales, delivery and installations, service maintenance, conducting inspections & investigations or even data collection.

Managing and co-ordinating tasks, scheduling activities, planning and monitoring activities and communicating can often be challenging.

Mobile Workforce Management is the automation of the entire end-to-end workflow management and operations of any field service workers. 

Mobile Workforce Management Synonyms

Mobile Workforce Management is also known as

  • Field Service Management
  • Job Scheduling Software
  • Job Management Software

Advantages of Mobile Workforce Management

It is increasingly clear that there needs to be a certain sense of discipline and streamlining of field operations and important to automate certain tasks within field sales and operations, primarily because it helps you to track your assets remotely and ensuring contact with your workforce when required. Enabling your team to get in touch when required.

Most importantly, engineers, sales representatives and customer care executives can easily send information, scan receipts, Invoice customers and retrieve other crucial information in a standardized and streamlined manner. Assisting in regulating your business and also bringing some order to what is usually a very chaotic mode of working.

Why choose Mobile Workforce Management

Work Force Management tools help you to stay in control. They assist in automating what can and should be automated leaving only the crucial human-human interactivity. Helping you to keep a record of all interactions and important data within a database, without you having to manually go through sales receipts, complaint slips and other such details.

A Field Force Management tool is a time-saver and efficiency tool for companies. Moreover, these tools help to automate several aspects of your day to day operations, leading to an increase in productivity and motivation.

Streamlining operations, will also ensure that important stakeholders are well informed and management visibility is enhanced. Helping your business to make smarter decisions and help serve your customers better.

Field Force Management is similar to an Enterprise Resource Planning (ERP) solution but is vastly different. It is specifically targeted at staff that work on the field and is intended to make their and your work more streamlined, transparent and easy to track.

Cloud based solutions help you automate

 Field Force Management is usually cloud based which means all data is stored and accessible on secure cloud servers. There is no question of losing important data or not being able to retrieve something important. If something goes missing, there will usually be a backup available. Field force management tools include the software, the hardware and also the kind of training that is required for users to use it efficiently.

The software usually helps in saving and processing information while the hardware helps employees to enter important data into devices while they are on the job. Sometimes, field force solutions can also be a mobile app which negates the need for a specific or special device.

This is very important when it comes to field jobs as carrying different devices can prove to be a cumbersome job. At the end of the day, field force solutions are meant to reduce the burden on staff and not actually inadvertently increase it.

Denizon?s FieldElite Mobile Workforce management application provides significant improvements in efficiency and service with a switch to digital working and the elimination of paperwork.

All the information that is stored on the cloud can be run through analytics software so that you get the kind of reports that you are looking for to improve your business.

Field Force Management Process

A field force management tool helps you to remain in contact with your staff while they are at work on the field. This helps you to track your personnel in real time. Field personnel or your staff can log in and enter their attendance using a smartphone. You can assign that particular day?s task remotely using a web console or your own smartphone.

Next, they can carry out whatever duties they need to while you get all the alerts that you set to receive. This helps to increase transparency. You can choose to receive alerts on your phone or on your desktop.

Finally, staff can tag completed tasks with audio and images, instead of they having to type reports. This helps to focus more on the job than on job reporting. Last but not the least, location tags help you to ensure that the job is done at the right place. Your staff will not be able to take your generosity for granted.

All in all, a field force management tool helps you to track and control your staff without you having to be physically present with them and this is the beauty of this tool.

Summary

Field Force Management helps companies to reduce administration expense and improve productivity. This helps to automate data integration which is usually done with the help of cloud servers. Moreover, you can set invoice parameters that help you to also keep track of stocks, inventories and engage in P.O. and task management.

A number of field force management users also use it as a tool to engage in credit management. Banks and insurance companies particularly find this tool helpful as payments can be received on the job, instead of asking customers to pay online or offline. This also helps in building valuable customer relationships and enhance loyalty.

Thirdly, a field force management tool helps to increase planning efficiency. This means, you will be able to allocate tasks and optimize routing. All this helps to increase your ROI at the end of the day and get back the money you invest on field force management.

Finally, you will have more control over productivity and sales thanks to automation of data collection. You will also have more control over the execution of tasks and that will invariably make your company leaner and smarter.

A Business Case for Sharing

We blogged about sharing services in a decentralised business context recently, and explained why we think why these should be IT-Based for speedy delivery. This is not to say that all shared services projects worldwide have been resounding successes. This is often down to the lack of a solid business case up front. We decided to lay out the logic behind this process.

Management Overview ? The overview includes a clear definition of why the current situation is unacceptable, the anticipated benefits of sharing, and an implementation plan were it to go ahead. The project should not proceed until the stakeholders have considered and agreed on this.

Alternatives Considered ? The next stage is to get closer to the other options in order to determine whether an alternative might perhaps be preferable. Substitutes for shared services are often doing nothing, improving the current method, and outsourcing the service to a third party.

The Bottom Line in Business ? Sharing services comes at an initial cost of infrastructure changes, and the impact on human capital (the latter deserves its own blog). The following need careful consideration from the financial angle:

Numbers to Work Through

  • Manpower to design and roll the project out in parallel with the existing organisation.
  • Capital for creating facilities at the central point including civil works, furniture and equipment and IT infrastructure.
  • The costs of travel, feeding and accommodation. These can be significant depending on the time that implementation takes.
  • The opportunity loss of diverting key staff – and the cost of temporary replacements – if appointing line staff to the project team.
  • Crystal-clear project metrics including (a) the direct, realisable savings (b) the medium and long-term effects on profit and (c) where to deploy the savings

Risk Management

Shared services projects don’t go equally smoothly, although planning should reduce the risk to manageable levels. Nonetheless it is important to imagine potential snags, decide how to mitigate them and what the cost might be.

We believe in implementing shared services on a pilot basis in the business unit that eventually provides them. We recommend building these out to other branches only when new processes are working smoothly.

Moving On From a Decision

We recommend you revisit your management overview, the logic behind it, the assumptions you made, and the costs and benefits you envisage before deciding to go ahead

The final step in proving a business case is doable should be fleshing out your roadmap into a detailed operations plan with dependencies on a spreadsheet.
