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.

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.

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.

How to Improve Corporate Efficiency through IT

When revenues are low, what do you do to improve your profit? Obviously, those same revenues should at least remain the same. So, the objective would be to deliver the same products and services for less cost. More for less. Such is the essence of corporate efficiency.

There are many things that can make a company inefficient. There are outdated procedures, poor coordination between departments, managers? lack of business visibility, and prolonged down times, to mention a few. As a company grows, these issues get more severe.

You can overcome all these by deploying the right IT solutions. But don’t IT solutions increase spending instead? Au contraire. The last couple of decades have seen the rise of IT solutions that help companies’realise obvious cost savings in no time.

Streamline processes and keep departments in-sync

Company inefficiencies are largely due to outdated systems and procedures. These systems and procedures were not built for the dynamic and complex business environments of today that are being shaped by increasingly onerous regulations, fierce and growing competition, significant economic upswings and downturns, new battlefronts (like the Web) and logistical strategies (like outsourcing), and IT-savvy crooks.

So when your employees force outdated systems to meet today?s business demands, they’re just not able to deliver. At least not efficiently.

Another major cause of inefficiency is the discordance among departments, business units, and even individual staff members themselves. There are those who still use highly personalised spreadsheets and other disparate applications, which make data consolidation take forever and the financial close a perennial headache.

Costly devices like mobile phones, netbooks, and tablet PCs, which are supposedly designed to provide better communication, are not fully maximised. If these are subsidised by the company, then they also contribute to company inefficiency.

One way to deal with these issues is to deploy server based solutions. By centralising your IT system, you can easily implement various improvements that can pave the way for better communication and collaboration, stronger security, faster processes and transactions, and shorter down times for troubleshooting and maintenance. All these clearly translate to cost savings.

Gain better visibility

Corporate efficiency can be improved if your decision makers can make wise and well-informed decisions, faster. But they can only do this if reports they receive from people down the line are timely, accurate, and reliable. Basically, data should be presented in a way for managers to gain quick insights from.

If your people take too much time scrutinising, interpreting, and reconciling data, you can’t hope to gain a significant competitive advantage. Equally important to managing an ongoing project is the speed at which you make a go/no go decision to start or stop a project. A wise, quick decision will help you avoid wastage.

The same holds true when making purchases and investment decisions. It’s all about quickly eliminating waste and investing only on those that will give you fast, positive returns.

Clear business visibility will allow managers to allocate resources where they are most effective, to pinpoint what products and services being offered are more profitable, and to identify which customers are giving better business from an overall perspective.

These are all possible with business intelligence. We know, we know. You’ll say BI solutions will force you to break the bank. Not anymore. At least, not all. There are already two main types of BI solutions: on-premise and SaaS. The latter will generally cost you less.

Of course, each type has its own advantages, and you’ll really have to look into the size of your organisation, the number of source systems your decision-making platform is connected to, integration requirements, budget, etc. to make sure you get the most out of your investment.

But IT solutions cost an arm and a leg

Again, not anymore. These days, you can find IT products that are faster, more functional, and more powerful than their predecessors at a fraction of the cost. When it comes to getting more affordable IT products and services, you now have many options.

For example, you can turn to open source solutions to save on license costs. These solutions are typically backed by vibrant and helpful communities where you can find an extensive source of technical support – many of which are for free. With popular open source products, you can easily tap from a large pool of developers with affordable rates any time you want to make system enhancements or customisation.

On another front, virtualization solutions allow you to save on CAPEX and OPEX by eliminating certain expenses normally used for setting up infrastructure or buying hardware and maintaining them. Server virtualisation, for instance, will allow you to consolidate servers and put them together into just one machine, while desktop virtualisation will enable you to eliminate unproductive hours associated with desktop down times by allowing you to redeploy a malfunctioning desktop very quickly.

Closely related to those are cloud-based solutions like SaaS (Software as a Service), IaaS (Infrastructure as a Service), and DCoD (Data Center on Demand). SaaS and IaaS will help you realize savings in acquisition and maintenance costs for software and hardware, while DCoD?s scalable services allow you to request for additional capacity, power and storage only as you need them, thus making you spend only according to your current infrastructure requirements.

Like we said, there are many, many options out there just waiting to be tapped.
