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.

Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

How Energy Conservation saved Fambeau River Paper

Rising energy costs caught this Wisconsin paper mill napping, and it soon shut down because it was unable to innovate. Someone else bought it and turned it around by measuring, modifying, monitoring and listening to people.

The Fambeau River Paper Mill in Prince County, Wisconsin USA employed 13% of the city?s residents until rising energy costs shut it down in 2006. Critics wrote it off as an energy dinosaur unable to adapt. But that was before another company bought it out and resuscitated it as a fleet-footed winner.

Its collapse was a long time coming and almost inevitable. Wisconsin electricity prices had grown a third since 1997, the machinery was antiquated and the dependence on fossil power absolute. So what did the new owners change, and is there anything we can learn from this?

The key to understanding what suddenly went right was the new owners? ability to listen. They requested a government Energy Assessment that suggested a number of small step changes that took them where they needed to go in terms of energy saving. These included enhancements in steam systems and fuel switch modifications. However they needed more than that.

The second game changer was tracking down key members of the old workforce and listening to them too. This combination enabled them to finally hire back 92% of the original labour force under the same terms and conditions – and still make a profit (the other 8% had moved on elsewhere or retired). The combined energy savings produced a payback plan of 5.25 years. Three years into the project their capital investment of $15 million had already clawed back the following electricity savings.

  • Evaporator Temperature Control $2,245,000
  • Hot Water Heat Recovery $2,105,000
  • Paper Machine Devronisers $1,400,000
  • Increased Boiler Output $1,134,000
  • Paper Machine Modifications; $761,000
  • Motive Air Dryer $610,000
  • Accumulator Savings $448,000
  • Densified Fuels Plant $356,000

In terms of carbon dioxide produced, the Fambeau River Paper Mill?s contribution dropped from 1 ton to 600 pounds.

How well do you know where your company?s energy spend is concentrated, and how this compares with your industry average; could you be doing better if you innovated, and by how much? Get these questions answered by asking ecoVaro how easy it could be to get on top of your carbon metrics. This could cost you a phone call and a payback on it so rapid it’s not worth stopping to calculate.

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.
