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.

Spreadsheet Woes – Ill-Equipped for an Agile Business Environment

These days, crucial business decisions have to be made in a split second. However, the quality of these decisions hinges quite often on timely, insightful information and relevant business reporting.

How effective is your business reporting solution in providing you with the information you need at the time you need it?

Chances are, like 75% of small and medium businesses, your company is using spreadsheets. True, spreadsheets are the most common go-to solutions for on-the-fly forecasting, but they may not be your best option for presenting information that require consolidation and in-depth analysis and involve a lot of number crunching, especially with critical data at stake.

Furthermore, spreadsheet-based reports are rarely produced in a timely manner. In today?s fast evolving business environment where flexibility, mobility, and timeliness are the order of the day, this simply won’t do.

Let’s take a look at the particular areas where spreadsheets fall short when it comes to providing dynamic and sound financial reports:

Collaboration

With rapidly changing market conditions, organisations have to conduct budgeting, forecasting, and planning more often. Hectic schedules and geographical distances aren’t a hindrance though, because technologies like the Internet, advanced telecommunications and mobile devices can put instantaneous collaboration at everyone?s fingertips.

But collaborative activities in a dynamic setting can only succeed if all participating individuals are given secure, real time and simultaneous access to the same relevant information. This way, every change made is automatically consolidated and projected unto the bigger picture for everyone to digest.

Alas, spreadsheets aren’t built for this.

Cost Efficiency

Whether we’re in a recession or not, cost efficiency has to be taken into consideration. Are spreadsheets really the cost-effective solution?

Think ?time is money?. With the length of time needed to prepare data, establish controls, consolidate reports and distribute copies, you’ll realise how expensive spreadsheets actually are.

The ability to innovate in a changing economic environment and limited resources – a valuable derivative of agile practices – can give your company a very significant advantage. But dedicating so much time on spreadsheet management can strip your organisation of room for innovation.

Quality of Reports

Business empires rise and fall on the power of relevant information. At the end of the day, top management should assess their sources of key performance reports, planning tools and budgeting applications using these parameters:

  • Does your financial reporting system give you the right information right when you need it?
  • Do the reports allow you to look beyond the numbers to spot trends or forecast changes in the market?
  • Do they furnish enough significant data for you to make informed decisions in good time?

Spreadsheets weren’t designed to analyse data on the enterprise level. As a result, spreadsheet reports often take far too long to prepare and more importantly, may lack the dimension and depth that are crucial in decision making.

Data Reliability

We’re all familiar with the risks associated with spreadsheets. This error-prone UDA can provide inaccurate information simply because of a broken link, an incomplete range, a deleted number, or an incorrect formula. In an active business scenario where data manipulation has to be done under constant time pressure, the risk probabilities escalate.

As they always say, ?If anything can go wrong, it will?. With spreadsheets, a lot of things could go wrong. Is this the kind of tool you?d like to work with when making fast, crucial decisions? If you’re still using spreadsheets, then you?d best forget about dynamic reports and rolling forecasts.

Inability to adapt to personnel turnover

A key challenge in maintaining the spreadsheet system is picking up where another left off. A user would find it difficult to debug, revise, or analyse a spreadsheet system he developed himself and the process becomes doubly complicated if or when another person takes over.

Starting from scratch is painfully counterproductive, so that a newcomer has to spend hours figuring out the original entries in the spreadsheet and the reports it yields.

While no one is indispensable in any organisation, it’s pretty much accurate to say that if a spreadsheet ?developer? leaves, it could momentarily halt the production of key finance reports. In a fast changing business landscape, such failure to monitor performance at critical times could sound the death knell for your company.

Recognizing Your Carbon Footprint

Countless times we have heard of the term ?carbon footprint?. Perhaps we have seen and heard it on TV or read it in newspapers, magazines and published articles. Indeed, it has been an expression familiar to everyone as it is always associated with climate change, carbon emissions, global warming, pollution and other environmental issues. Carbon footprint is real. It exists and, in fact, continues to affect the world we live in.

Defining Carbon Footprint

Two essential words comprise the term carbon footprint. Fundamentally, ?carbon? means the carbon dioxide circulating in the atmosphere. It is also the general word used for other greenhouse gasses emitted into the air. On the other note, ?footprint? refers to impact or effect.

Think about the footprints people leave on the beach sand upon walking on the shore. That is exactly what carbon footprint is like. It’s about the impact humans leave on the earth in the form of carbon dioxide and other greenhouse gases.

Calculating Your Personal Carbon Footprint

The food we eat, products we use, vehicles we ride on and electricity we consume emit carbon dioxide. In fact, our activities, lifestyle, homes, and countries contribute to climate change. And carbon footprint is the best estimate we can get of the full impact our doings affect the earth. It quantifies the amount of our carbon emission. With this, knowing how to calculate your personal carbon footprint is important.

There are various standards in calculating one?s carbon footprint. There is the so-called ?lifestyle assessment? and the input-output analysis. Lifestyle assessment works by adding up all the feasible emission pathways while the input-output analysis involves determining the total emissions of a particular country, dividing it by the carbon-emitting sectors and estimating the overall emissions of each sector. The input-output analysis makes sure that no emission pathway is missed out.

Calculating your carbon footprint manually is an effective way for you to understand your emissions better. You just need a lot of patience to learn how each footprint is generated. Moreover, there are also several resources online that can help you calculate your carbon footprint. Online carbon calculators are abundant across the web. To make your life simpler, you can opt to try those online calculators and easily determine your carbon emissions. However, such calculators vary in scope. So make sure that the online carbon calculator, you choose, is one that?includes emissions both direct and indirect.

Avoiding Toe Prints

A toe print is a portion of a footprint. Sometimes, people are misled in their calculations because they only get a carbon toe print instead of a footprint. The idea is that, you should cover a smart scope of your carbon emissions. Not only measuring a portion, but the whole.

Say for example, running a conventional car. The carbon emitted from the car is not only the fuel combustion from the diesel or petrol.? Likewise, the carbon released as the gas was processed and transported to your nearby gasoline station is also an addition to your carbon footprint. If you do not understand this, you will end up calculating your direct emissions while neglecting the indirect ones.

Be wise in calculating your carbon footprint. And when in doubt, whether you are an individual or a business entity, you should seek help from experts who can do it right.

How Volvo Dublin achieved Zero Landfill Status

The sprawling New River Valley Volvo plant in Dublin, Virginia slashed its electricity bill by 25% in a single year when it set its mind to this in 2009. It went on to become the first carbon-neutral factory in 2012 after replacing fossil energy with renewable power. Further efforts rewarded it with zero-landfill status in 2013. ecoVaro decided to investigate how it achieved this latest success.

Volvo Dublin?s anti-landfill project began when it identified, measured and evaluated all liquid and solid waste sources within the plant (i.e. before these left the works). This quantified data provided its environmental project team with a base from which to explore options for reusing, recycling and composting the discards.

Several decisions followed immediately. Volvo instructed its component suppliers to stop using cardboard boxes and foam rubber / Styrofoam as packaging, in favour of reusable shipping containers. This represented a collaborative saving that benefited both parties although this was just a forerunner of what followed.

Next, Volvo?s New River Valley truck assembly plant turned its attention to the paint shop. It developed methods to trap, reconstitute and reuse solvents that flushed paint lines, and recycle paint sludge to fire a cement kiln. The plant cafeteria did not escape attention either. The environment team made sure that all utensils, cups, containers and food waste generated were compostable at a facility on site.

The results of these simple, and in hindsight obvious decisions were remarkable. Every year since then Volvo has generated energy savings equivalent to 9,348 oil barrels or if you prefer 14,509 megawatts of electricity. Just imagine the benefits if every manufacturing facility did something similar everywhere around the world.

By 2012, the New River Valley Volvo Plant became the first U.S. facility to receive ISO 50001 energy-management status under a government-administered process. Further technology enhancements followed. These included solar hot water boilers and infrared heating throughout the 1.6 million square foot (148,644 square meter) plant, building automation systems that kept energy costs down, and listening to employees who were brim-full with good ideas.

The Volvo experience is by no means unique although it may have been ahead of the curve. General Motors has more than 106 landfill-free installations and Ford plans to reduce waste per vehicle by 40% between 2010 and 2016. These projects all began by measuring energy footprints throughout the process. ecoVaro provides a facility for you to do this too.
