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.

Choosing Routes for ESOS Compliance

Along the introduction of Energy Savings Opportunity Scheme in UK is the quick emergence of various companies that offer ESOS compliant services. While some energy audit providers can help, qualified businesses should understand what their compliance options are, how these routes work and learn both the pros and cons in order to carefully take their pick.

Independent ISO 50001 Certification

ISO 50001 comprises the integration and application of processes geared to motivate energy saving and overall improvement. Simply stated, it is a framework that drives the organisation’s governance to realise energy saving strategies by allocating resources and participating in energy management. The good thing about ISO 50001 is that it includes an energy review that documents ideas and opportunities to save more energy.

However, ISO 50001 does not obligate organisations to cover 90% of their overall energy consumption. In case of partial coverage, the company needs to undergo additional energy assessments to evaluate all the significant energy consumption areas.

In order for an ISO 50001 certification to be valid, it must be certified by the United Kingdom Accreditation Service (UKAS), by an accreditation body which is a member of the International Accreditation Forum, or by a body accredited by another EU member state?s national accreditation body.

Display Energy Certificates and Green Deal Assessments

These two kinds of energy assessment reports can also contribute to ESOS compliance. Both of them are carried out by qualified lead assessors and valid for 10 years. However, they are only based on the building structures and services. They do not cover the overall significant areas in energy consumption. Since these reports are valid for 10 years, they would be used for two ESOS reporting periods. Thus, they would not be as current as the ISO 50001 certification. Aside from that, the assessments are purely based on energy efficiency and anyone can qualify to use the software that produce the certifications after taking the accreditation course.

Energy Audits

A successful energy audit leads to better understanding of the company?s energy consumption, identify alternatives, determine cost-effective energy saving opportunities and stimulate energy efficiency. Energy audits are beneficial to the organisation. What makes it complex is that the organisation applying it, needs to clearly define the scope and type of energy audit to use in order to comply with ESOS. Furthermore, the organisation also has to identify the teams that would be competent enough to do the audit work for the building, transport and industrial area, respectively.

Each route is not formed equal. Thus, organisations have the option to either choose one or combine the routes and meet their company needs. The options mentioned are different approaches to ESOS and the core value is to grab the opportunity towards acquiring more savings through efficient energy system.

UK Hauliers Pull Together on ESOS

ESOS is what UK business needed, to encourage it to become more responsible for the environmental consequences of making money. Government has met with industry leaders to hammer out the finer details. Now there are heartening signs of intra-industry collaboration, for the example the FTA approach we discuss here.

The Freight Transport Association (FTA) is one of the UK?s biggest trade associations, and exists to represent the interests of companies moving goods by air, rail, sea and road. It is their representative at national, European and local level that advises them on legal compliance. In February 2015, it announced plans to help the industry comply with ESOS too.

The association has been active since the announcement of the UK?s Energy Saving Opportunity Scheme. It has engaged with government and membership through the portal of its Logistics Carbon Reduction Scheme (LCRS). The Environment Agency has singled this out as a benchmark other industries could follow.

FTA general manager for consultancy and tendering Karen Packham recently said, ?With our highly experienced and fully qualified team of transport auditors ?the FTA is best placed to offer practical advice and is able to provide specialist audits to ensure members are fully compliant ? and will gain all the benefits that the scheme has to offer.?

These co-audits with Environment Agency specialists advising, will focus on the full range of operational and supporting activities, and ensure that all haulage companies with over 250 employees do the following:

  • Assess energy use across their full spread of buildings, transport media and industrial activity
  • Examine energy-intensive pressure points and identify savings opportunities that provide financial benefit
  • Nominate an ESOS person to conduct future audits, or oversee and approve them independently
  • Report to the Environment Agency as scheme administrator per statutory intervals

Ecovaro has energy management software that turns metrics into high-level information that busy people understand. Give us a call if you are puzzling how best to present your data. We believe two heads can achieve so much more together.

What is Business Intelligence?

How well do you know your customers? That is, can you actually pinpoint which among them are you most profitable with and which are making you spend more? Are you content with the accuracy of your forecasts and market predictions? Do you feel you’re spending more on legal costs and regulatory compliance than you should?

Your IT department may be handling these concerns pretty well but perhaps you’d like to know how you can further improve things.

What we’ve got is an IT solution wrapped in a fancy name called ‘Business Intelligence’ or BI. If you think that’s too strong a term, we invite you to read more below, then you be the judge.

Dashboards – Determine the health of your business at a glance

Most drivers rarely make use of their car’s dashboard. After all, you can still reach your destination by just using the steering wheel, pedals, gear stick and so on. But that’s not exactly the most efficient way to drive, right?

If you want to save on fuel, you’ll want to glance on the RPM and speedometer from time to time. You might also want to utilise the trip meter to determine which route is the shortest to a given destination. Other dashboard components like the fuel gauge, tire pressure gauge, engine temperature indicator, and volt meter can likewise provide information about your car’s health.

The same concept applies to business management. If you want to run your business intelligently, you can make use of BI dashboards. These are tools in a typical business intelligence package that will allow you to determine the health of your business via a set of smartly configured gauges and other intuitive graphical representations.

So that, literally, at a mere glance, you’ll already know whether various units in your company are working efficiently. A dashboard will also give you instant feedback of the strategies you’ve recently implemented; to let you know if things are working as planned.

If you want more information than a dashboard can provide, our BI packages also include highly customised reports.

Reports that help you decide faster

Dashboards are great for getting valuable information at a glance but they won’t tell you everything. For more details, you’ll need to view highly customised reports. Our reports are tailor made for each user. We see to it that, by default, each person gets the information he needs the most.

If you belong to the sales department, you normally won’t need a presentation of the data that is appropriate for people in accounting. That way, you don’t spend time filtering. Instead, you and your people can move on to making well-informed decisions.

Our BI systems make use of your vast collection of data to provide reports that will organise your regulatory requirements and call your attention to approaching deadlines. The same system will provide the right information for your people on the field. If your team members are equipped with smart phones and Pocket PCs, they can retrieve whatever it is they need to know to close deals, make sales, and serve clients faster than the competition.

Generating logical information from disparate sources of data scattered over an enterprise-wide organisation is no easy task. But we’ll make it look simple. That’s because we’ve got the expertise to bring it all together into a robust data warehouse and to extract them in the form of reports and dashboards through OLAP.

OLAP and Data Warehousing – Powering the generation of actionable information

Want to know how to generate reports with the highest degree of accuracy and reliability? In theory, what you need is a single repository or a data warehouse. That is, order receipts, sales invoices, as well as customer & supplier data is integrated with regulatory details, personnel data, and others. These are all specially organised for future reporting and analysis.

However, data, no matter how all-embracing, is useless until it is processed into actionable information. Through OLAP or Online Analytical Processing, you can seamlessly collect all relevant data from your vast repository to answer queries like “What is our company’s profitability for the 2nd quarter in all identified key cities for our top-of-the-line products?”.

The strength of OLAP lies in its inherent ability to perform data analysis and very complex calculations, thus enabling it to return complex queries much faster than other database technologies. It is therefore suitable for very large data sources, i.e., data warehouses.

Dashboards and reports will only give your organisation the edge if the information retrieved is reliable, fast, and accurate – exactly the kind OLAP is so good at.

Mobile BI – Step back and see the big picture anytime, anywhere

Spreadsheets are great for displaying detailed information. However, in today’s highly competitive market, retrieving information that matters the most in the shortest possible time is vital in maintaining a sizeable lead over the competition. To step back and see the big picture, you’ll need insightful tools like dashboards and automatically generated reports.

Reports can be beamed to mobile devices such as smart phones and Pocket PCs. They can also be viewed on eBook readers as well. You can also do the same tasks with spreadsheets. But imagine how you’d need to scroll over a large spreadsheet on any of these mobile devices just to know which customer in your current location has performed well over the last month.

If you really want to make quick, well-informed decisions, BI dashboards for mobile devices is the way to go. You can make use of various business objects such as drill-able charts, performance metrics, and metric trend graphs to make crucial decisions even when on you’re in the field.
