Using Pull Systems to Optimise Work Flows in Call Centres

When call centres emerged towards the end of the 20^th 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.

New Focus on Monitoring Soil

There is nothing new about monitoring soil in arid conditions. South Africa and Israel have been doing it for decades. However climate change has increased its urgency as the world comes to terms with pressure on the food chain. Denizon decided to explore trends at the macro first world level and the micro third world one.

In America, the Coordinated National Soil Moisture Network is going ahead with plans to create a database of federal and state monitoring networks and numerical modelling techniques, with an eye on soil-moisture database integration. This is a component of the National Drought Resilience Partnership that slots into Barrack Obama?s Climate Action Plan.

This far-reaching program reaches into every corner of American life to address the twin scourges of droughts and inundation, and the agency director has called it ?probably ?… one of the most innovative inter-agency tools on the planet?. The pilot project involving remote moisture sensing and satellite observation targets Oklahoma, North Texas and surrounding areas.

Africa has similar needs but lacks America?s financial muscle. Princeton University ecohydrologist Kelly Caylor is bridging the gap in Kenya and Zambia by using cell phone technology to transmit ecodata collected by low-cost ?pulsepods?.

He deploys the pods about the size of smoke alarms to measure plants and their environment.?Aspects include soil moisture to estimate how much water they are using, and sunlight to approximate the rate of photosynthesis. Each pod holds seven to eight sensors, can operate on or above the ground, and transmits the data via sms.

While the system is working well at academic level, there is more to do before the information is useful to subsistence rural farmers living from hand to mouth. The raw data stream requires interpretation and the analysis must come through trusted channels most likely to be the government and tribal chiefs. Kelly Caylor cites the example of a sick child. The temperature reading has no use until a trusted source interprets it.

He has a vision of climate-smart agriculture where tradition gives way to global warming. He involves local farmers in his research by enrolling them when he places pods, and asking them to sms weekly weather reports to him that he correlates with the sensor data. As trust builds, he hopes to help them choose more climate-friendly crops and learn how to reallocate labour as seasons change.

Excel Spreadsheet Conversion to SQL Reports

Spreadsheets are flexible, inexpensive and easy to use. They are especially handy when it comes to beating report submission deadlines or making impromptu data computations.

Unfortunately, organisations heavy reliance on spreadsheets have made these User Developed Applications (UDA) into high-risk office tools. Simple spreadsheet errors like leaving out a negative sign or a cut-and-paste mistake have already caused million-dollar discrepancies. Also, when a fraudulent employee enters into the picture, the risks become unimaginable.
Think TransAlta’s spreadsheet cut-and-paste glitch (the company later called this a ‘simple clerical error’) which caused the energy firm a whopping $24 million loss or Fidelity’s overstatement of its earnings owing to the omission of the minus sign on the spreadsheet of a $1.3 billion net capital loss.

Denizon can convert your Excel Spreadsheets to a web based SQL Server Reporting Services (SSRS). It does not import Excel data, rather it allows the creation and deployment of reports in a more efficient manner by querying the data.

So what is the problem with Spreadsheets?

Plagued with risk issues and vulnerable to fraud
Lacking in control features especially when copied, edited and emailed between many users
A burden to regulation compliance e.g. SOX (Sarbanes-Oxley)

Moreover:

Accidental copy-paste/Omission of a negative sign/Erroneous range selection
Incorrect data input or unintentional deletion of a character, cell, range, column, or row
Possibility of the user working on the wrong version
Prone to inconsistent company-wide reporting
Often ‘defenceless’ against unauthorised access

See Top 10 Disadvantages of Spreadsheets

What makes SQL Server Reporting Services better than Spreadsheets?

Free from spreadsheet risks & equipped with built-in controls that substantially reduce risks to data
Less prone to fraud
More suitable for regulatory compliance e.g. SOX
Designed for an agile business environment

Automatic consolidation eliminates errors and wasted time caused by tedious copy-pasting of data and linking of cells
Better collaboration capabilities allows team members to bring their heads together for planning, budgeting, and reporting even while on the go
Mobility support enables users to input data or retrieve information through their wireless mobile device

Superior sharing features ensures that everyone is exactly on the same page and viewing real-time information
Dashboards provide insightful information at-a-glance through KPIs, graphs, and various metrics
Drill-downs enable users to investigate unusual figures and gain a better understanding of the details that contribute to the big picture
Easy to learn interfaces allow your organisation to cope with fast personnel turnaround or Mergers & Acquisitions

Eck Industries Sheds Fresh Light

William Eck began his business in 1948 in a 650m² garage building. The aluminium foundry prospered, and now has an 18,500m²factory in Manitowoc, Wisconsin employing 250 people casting a variety of casings. Like high-tech industries around the globe it needs effective illumination. After it measured its carbon footprint, it realised it needed energy efficient lighting too.

When Eck Industries began its review it had around 360 high-pressure sodium lights throughout the plant. Their operating cost was substantial. After taking independent advice from an independent agency they realised they needed to replace these with more energy-efficient fluorescent lights that consume half as much energy.

The feasibility team conducted performance tests to determine the optimum solution. After selecting enclosed, gasketed and waterproof T8 fluorescents (available in G13 bipin, single pin and recessed double contacts) they collaborated with the supplier to calculate the best combination of 4 and 6 bulb fixtures.

The fittings they chose cost $60,000 plus $10,000 installation. However a $33,000 energy rebate wrote down 47% of this immediately. They achieved further energy savings by attaching motion sensors to lights over low-traffic walkways.

The retrofit was a huge success, with an 8 month payback via a direct operating saving of $55,000 a year. Over and above enhanced illumination Eck Industries slashed 674,000 kilowatt hours off its annual lighting bill. During the 20 year design life, this equates to a total 13.5 million kilowatt hours. Other quantifiable benefits include 443 tons less carbon, 2 tons less sulphur dioxide, and 1 ton less nitrogen oxide per year.

Many companies face similar opportunities but fail to capitalise on them for a number of reasons. These may include not being aware of what is available, lacking technical insight, being short of working capital and simply being too busy to focus on them.

Eck Industries got several things right. Firstly, they consulted an independent specialist; secondly they trusted their supplier to provide honest advice, and thirdly they accepted that any significant saving is worth chasing down. Other spin-offs were safer, more attractive working conditions and an opportunity to take their foot off the carbon pedal. This is an excellent example of what is possible when you try.

If you have measured your illumination cost and are concerned about it (but are unsure what the metric means within the bigger picture) then Ecovaro offers online reports comparing it with your industry average, and highlights the cost-benefits of alternative lighting.
