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.

Why Spreadsheets can send the Pillars of Solvency II Crashing Down


Solvency II is now fast approaching and while it may provide added protection to policy holders, its impact on the insurance industry is not all a bed of roses. Expect insurance companies to restructure, increase manpower, and raise spending on actuarial operations and risk management initiatives. Those that cannot, will have to go. But what have spreadsheets got to do with all these?

Well, spreadsheets aren’t really the main casts in this blockbuster of a regulatory exercise but they certainly have a significant supporting role to play. Pillar I of Solvency II, which calls for improved supervision on internal control, risk management, and corporate governance, and Pillar II, which tackles supervisory reporting and public disclosure of financial and other relevant information, both affect systems that have high-reliance on spreadsheets.

A little background about spreadsheets might help.

Who needs an IT solution when you can have spreadsheets?

Everyone in any organisation just love spreadsheets; from the office clerk to the CEO. Because they’re so easy to use (not to mention they’re a staple in office computers), people employ them for processing numbers and as an all-around tool for planning, forecasting, reporting, complex modelling, market data analysis, and so on. They make such tasks faster and easier. Really?

You probably haven’t heard of spreadsheet hell

Unfortunately, spreadsheets do have certain shortcomings. Due to their inherent structure and lack of controls, it is so easy to commit simple errors like an accidental copy paste, an omission of a negative sign, an incorrect data input, or an unintentional deletion. Such shortcomings may seem harmless until your shareholders discover a multi-million discrepancy in your financial report.

And because spreadsheet errors can go undetected for a long time, they are constant targets of fraudsters. In other words, spreadsheets are high risk applications.

Solvency II Impact on Spreadsheet-based Financial and IT Systems

Regulations like Solvency II, are aimed at reducing risks to manageable levels. Basically, Solvency II is a risk-based system wherein a company?s capital requirements will depend on its measured riskiness. If companies want to avoid facing onerous capital requirements, they have to comply.

The three pillars of Solvency II have to be in place. Now, since spreadsheets (also known as User Developed Applications or UDAs) are high-risk applications with weak control features and prone to produce inaccurate reports, companies will have a lot of work to do to establish Pillars II and III.

There are at least 8 articles that impact spreadsheets in the directive. Article 82, for example, which requires firms to ensure a high level of data quality and accuracy, strikes at the very core of spreadsheets? weakness.

A whitepaper by Raymond Panko entitled ?Spreadsheets and Sarbanes-Oxley: Regulations, Risks, and Control Frameworks? mentioned that 94% of audited real world operational spreadsheets that were included in his study were found to have errors and that an average of 5.2% of all cells in the audited spreadsheets had errors.

Furthermore, many articles in the directive call for the enforcement of better documentation. This is one thing that’s very tedious and almost unrealistic to do with spreadsheets because just about anyone uses them. Besides, with different ‘versions? of the same data existing in different workstations throughout the organisation, it would be extremely difficult to keep track of them all.

Because of spreadsheets you now need an IT solution

It is clear that, with the growing number of regulations and the mounting complexity of tasks needed for compliance, spreadsheets no longer belong in this era. What you need is a server-based solution that allows for seamless collaboration, data reliability, data consistency, increased security, automatic consolidation, and all the other features that make regulation compliance more doable.

One important ingredient for achieving Solvency II compliance is sound data risk management. Sad to say, the ubiquitous spreadsheet will only expose your data to more risks.

How to create a custom form with Field Elite

A common requirement for most Field Service Workers is to complete various forms and paper based inspection checklists when visiting customer sites and remote area locations.  Often the data collected is often used in collaboration efforts across multiple teams and organisations. 

Using paper forms, binders, cameras, and filing cabinets can make this process complicated, frustrating, and often, near impossible.

If you consider that, even though we are entering the third decade of the new millennium and despite the proliferation of Smart Phones and Tablet computing an incredibly large percentage of field service teams are still making use of paper based systems!

Field Elite Customised forms

Field Elite enables Field Service organisations to easily create their own customised forms which can be attached jobs. 

The creation of forms can be done using the Web Based Administration Portal which is provided as standard to all customers when signing up for an account.

To access the form builder from Side Navigation navigate Settings –> Form Templates –> Create Form


You will then be presented with Form Builder utility which will contain an Empty Default Form and a list of fields types you are able to insert.

There are a variety of fields you can use to create all manner of forms. There is no restriction on the number of fields or field types you can choose to create forms suitable for your purpose.

If you can think it you can create it

In the example, we’ll work through, we are going to create a Simple Conference Room Inspection  Report, to be used by Facility Managers to assist in carrying room inspection reports for conference centres.

To add fields to your form simply Drag and Drop the fields onto the form.

Once you have completed adding which fields you require to your form and you are satisfied with the layout.

Select Settings tab to provide a meaningful name for your form.

You can also select a Form Layout you wish for your form.  For the purpose of this post we are going to leave it as Vertical.

Once you are satisfied with your form you can select Save Form 


Once your form has been saved it will be available for selection when defining jobs in the system.

Summary

It is really easy to define custom forms using the Field Elite from templates module.  The Form Template module enables you to create any manner of forms your organisation may require.

Using Pull Systems to Optimise Work Flows in Call Centres

When call centres emerged towards the end of the 20th century, they deserved their name ?the sweatshops of the nineties?. A new brand of low-paid workers crammed into tiny cubicles to interact with consumers who were still trying to understand the system. Supervisors followed ?scientific management? principles aimed at maximising call-agent activity. When there was sudden surge in incoming calls, systems and customer care fell over.

The flow is nowadays in the opposite direction. Systems borrowed from manufacturing like Kanban, Pull, and Levelling are in place enabling a more customer-oriented approach. In this short article, our focus is on Pull Systems. We discuss what are they, and how they can make modern call centres even better for both sets of stakeholders.

Pull Systems from a Manufacturing Perspective

Manufacturing has traditionally been push-based. Sums are done, demand predicted, raw materials ordered and the machines turned on. Manufacturers send out representatives to obtain orders and push out stock. If the sums turn out wrong inventories rise, and stock holding costs increase. The consumer is on the receiving end again and the accountant is irritable all day long.

Just-in-time thinking has evolved a pull-based approach to manufacturing. This limits inventories to anticipated demand in the time it takes to manufacture more, plus a cushion as a trigger. When the cushion is gone, demand-pull spurs the factory into action. This approach brings us closer to only making what we can sell. The consumer benefits from a lower price and the accountant smiles again.

Are Pull Systems Possible in Dual Call Centres

There are many comments in the public domain regarding the practicality of using lean pull systems to regulate call centre workflow. Critics point to the practical impossibility of limiting the number of incoming callers. They believe a call centre must answer all inbound calls within a target period, or lose its clients to the competition.

In this world-view customers are often the losers. At peak times, operators can seem keen to shrug them off with canned answers. When things are quiet, they languidly explain things to keep their occupancy levels high. But this is not the end of the discussion, because modern call centres do more than just take inbound calls.

Using the Pull System Approach in Dual Call Centres

Most call centre support-desks originally focused are handling technical queries on behalf of a number of clients. When these clients? customers called in, their staff used operator?s guides to help them answer specific queries. Financial models?determined staffing levels and the number of ?man-hours? available daily. Using a manufacturing analogy, they used a push-approach to decide the amount of effort they were going to put out, and that is where they planted their standard.

Since these early 1990 days, advanced telephony on the internet has empowered call centres to provide additional remote services in any country with these networks. They have added sales and marketing to their business models, and increased their revenue through commissions. They have control over activity levels in this part of their business. They have the power to decide how many calls they are going to make, and within reason when they are going to make them.

This dichotomy of being passive regarding incoming traffic on the one hand, and having active control over outgoing calls on the other, opens up the possibility of a partly pull-based lean approach to call centre operation. In this model, a switching mechanism moves dual trained operators between call centre duties and marketing activities, as required by the volume of call centre traffic, thus making a pull system viable in dual call centres.
