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.

2015 ESOS Guidelines Chapter 2 – Deadlines and Status Changes

The ESOS process is deadline driven and meeting key dates is a non-negotiable. The penalties for not complying / providing false or misleading information are ?50,000 each. Simply not maintaining adequate records could cost you ?5,000. The carrot on the end of the stick is the financial benefits you stand to gain.

Qualifying for inclusion under the ESOS umbrella depends on the status of your company in terms of employee numbers, turnover and balance sheet on 31 December 2014. Regardless of whether you meet the 2014 threshold or not, you must reconsider your situation on 31 December 2018, 2022 and 2026.

Compliance Period Qualification Date Compliance Period Compliance Date
1 31 December 2014 From 17 July 2014* to 5 December 2015 5 December 2015
2 31 December 2018 From 6 December 2015 to 5 December 2019 5 December 2019
3 31 December 2022 From 6 December 2019 to 5 December 2023 5 December 2023
4 31 December 2026 From 6 December 2023 to 5 December 2027 5 December 2027

Notes:

1. The first compliance period begins on the date the regulations became effective

2. Energy audits from 6 December 2011 onward may go towards the first compliance report

Changes in Organisation Status

If your organisation status changes after a qualification date when you met compliance thresholds, you are still bound to complete your ESOS assessment for that compliance period. This is regardless of any change in size or structure. Your qualification status then remains in force until the next qualification date when you must reconsider it.

Symbion Pharmacy Services? Definition of Responsibility

A ?symbion? is an organism in a symbiotic (i.e. mutually beneficial) relationship with another one. In the case of Australia?s giant Symbion Pharmacy Services, this means supplying and delivering over-counter Chemmart medicines to more than 3,000 hospital and retail pharmacies, while remaining mindful of its carbon footprint.

In 1999, the company with the tagline ?life matters? and a desire to be seen as ?a good corporate citizen? decided it was time to measure exactly what it was pumping out from 12 facilities and over 200 vehicles. This was a voluntary decision as even now there is still no carbon emissions law in Australia (although no doubt being a ?first mover? will put the company in a competitive position when this inevitably comes).

Symbion decided to install emission detection devices and connect these to a central monitoring system with the intention of managing what these measured. There were two stages to this process. First, Symbion determined its reporting requirements based on one of its larger warehouses. Following that, it established a carbon footprint for each of its wholly owned and managed facilities. This put it in a position to:

  • Analyse total emissions down to a level of detail where it understood the contribution of each source
  • Use big data management tools to identify carbon hotspots for priority remedial action
  • Inform the affected workforce, explain the monitoring system and keep them in the loop
  • Separately manage energy abatement programs such as lighting and delivery routes

The program also had productivity spin-offs in that it focused management attention on the processes behind the emissions that were ripe for material and system improvements. It also provided marketing leverage. Symbion?s customers are in the wellness business, ahead of the curve when it comes to how emissions contribute to chronic illness, and aware of the cost of this in terms of human capital.

EcoVaro could help you manage your throughputs by analysing your data on our cloud-based system. This includes trending your metrics, comparing them to your industry seasonal average, and providing you with a business-like view of how well you are doing.

Our service reduces your reliance on (and the cost of) third party audits, and simplifies the reporting process to your controlling authority. It simply makes more sense to contract your software out this way, and only pay for it when you need it.

How Bombardier Inc. scored a Bulls Eye

When travelling anywhere in the world on land, sea or air, chances are, you will travel courtesy of something made by aerospace and transportation company Bombardier based in Montreal, Canada. In 2009, it set itself the goal of carbon neutrality by 2020. In other words, it hoped to remove as much carbon dioxide from the atmosphere as it was putting in.

By 2012, Bombardier concluded it was not going to become carbon neutral by 2020 at its current rate of progress. It discounted purchasing carbon offsets because it believed it would serve its interests better by introducing new energy-saving products to market faster. That way, it would achieve its objectives vicariously through the decisions of its customers. But that was not all that forward-thinking Bombardier did. It also set itself the following inward-facing objectives:

  • Reduce carbon footprint through efficient use of energy and less emissions
  • Involve the Bombardier workforce to raise awareness of behaving responsibly
  • Implement sustainable initiatives to further reduce the company carbon footprint

Specific Examples

At its Wichita site, Bombardier (a) fitted a white roof and insulation reducing summer energy consumption by 40%, (b) added an energy recovery wheel to balance air circulation, and (c) introduced skylights with integrated controllers to lower energy consumption by lighting.

At Mirabel, it enhanced the flue-gas management system by adding a pressure differential damper.

At Belfast, Bombardier (a) optimised HVAC systems to reduce pressure on chilling and air-handling plants, (b) installed solar panels on the roof, and (c) obtained approval for a waste-to-energy plant that will convert 120,000 tonnes of non-recyclable waste material annually.

By the end of 2013, Bombardier had already beaten its immediate targets by:

  • Reducing energy consumption by 11% against 2009
  • Reducing greenhouse gas emission by 23% against 2009
  • Reducing water consumption by 6% against 2012

Future Plans

Bombardier will never stop striving to reach its goal of carbon neutrality by 2020. It has a number of other projects in the pipeline waiting for scarce resources to fund them. During 2014, it continued with energy efficient upgrades at its French, Hungarian, Polish, Swiss, and UK plants.

These include consumption monitoring systems, LEDs for workshop lighting, new heating systems, and outdoor energy-saving tower lighting. The monitoring is important because it helps Bombardier focus effort, and provides measured proof of progress.
