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.

ESOS Facts on a Page

The UK?s ESOS energy saving program stands for ?Energy Savings Opportunity Scheme?. Its purpose is to reduce demand – and hence fossil-based pollution at both ends of the supply chain. It currently applies to large UK companies only. However its guidelines are also valuable input to smaller firms voluntarily going greener.

The program threshold is 250 employees and / or turnover or at least ?UK50 million. This affects approximately 9,000 UK firms, with others below the threshold wondering whether the government plans to lower it. In essence, ESOS requires that qualifying businesses complete comprehensive audits of energy use and opportunities at least every fourth year.

The plan is carrot and stick. Compliant companies will probably uncover significant savings when they stop and measure. They may even unearth carbon credits they can sometime exchange for cash. Reactionary firms who try to duck the issue will feel Her Majesty?s wrath through stiff penalties. In time, they may find it harder to attract investors. If ESOS affects your company, then the wise thing could be complying by the first deadline of 5 December 2015.

To do so, you must conduct an energy audit and report it to the UK Environment Agency. This comprises

  1. Measuring total energy use across processes, transport and facilities
  2. Pie charting 90% of this to identify areas that are energy intensive
  3. Singling out cost-effective energy-saving projects in high use areas
  4. Submitting your report to the Environment Agency ahead of the deadline

ecoVaro recommends affected companies do not leave this to the last minute. While having ISO 50001 may exempt some from ESOS, the regulations are far from straightforward and it will take months to reach complete clarification. We would like to suggest a more balanced approach.

ESOS is a wonderful incentive to save energy costs while contributing to a better future for the kids. The Energy Savings Opportunity Scheme is precisely that. The cost of energy has crept up on us to the extent that we have to do something, government or no government.

Measuring energy consumption is as simple as installing meters at critical points in the flow, and you probably have many of them anyway. Once you have your data you no longer have to crunch the numbers. ecoVaro can do this for you and return the result in the form of handy graphs and spreadsheets.

Cloud Computing Trends: Where is the Cloud Headed Next?

Cloud adoption has been quick and painless at the consumer level. For instance, everyone’s on Gmail, YouTube, Facebook and Twitter on a daily basis yet most think nothing of the fact that they’re already using cloud-based services. Small businesses have also discovered how cloud solutions have raised efficiency in the workplace up a notch or two, while also bringing about significant cost savings. Cloud applications, particularly those for communication, file sharing, office software, backup and storage, and customer management, have rapidly grown in usage among SMBs.

In the same manner, large corporations are starting to see the potential of moving some of their IT department, whether its infrastructure or network management, to the cloud. By all indications it would seem that whether we are ready for it or not, cloud computing technology is here for the long haul.

So where is the cloud headed to next? In this post we examine the trends in the world of cloud computing and what likely lies in store in the near future for cloud users.

Focus on Security

Security has always been a key concern in the cloud computing industry and this will not go away anytime soon. If anything, data security in the cloud will only get to be in the limelight even more as cloud adopters grow in number. That’s why we expect professional cloud services providers to start implementing measures that will help slowly build up confidence in cloud security.

We should soon see more advanced security techniques and protocols that would increase the overall level of privacy and protection for cloud-stored information. Tighter security for login encryptions and prevention of unauthorized access are priority although there are a lot more issues that may need to be addressed. Now it remains to be seen whether these moves are enough for corporate clients to put their full trust in the cloud. But then again, they can always find ways to stay secure while making use of cloud computing where they can, which brings us to the next cloud trend.

Hybrid Approach

Large businesses are taking a longer time to get used to and actually use cloud services, and understandably so. After all, these companies have more at stake when it comes to dealing with such valid issues as security, compliance, outages, legacy systems, and more. However, they also cannot ignore the very appealing characteristics of the cloud. For big companies that have substantial IT needs, scalability, business agility, and faster deployment are listed as the biggest draws of the cloud.

This is why analysts predict that as as these businesses look toward leveraging the benefits of the cloud while at the same time maintaining control over mission critical data and systems, the use of a hybrid approach, i.e. putting some services in a public and at the same time opting to utilize a private cloud for other applications, will see enormous growth.

Mobile Cloud Computing

The BYOD or Bring Your Own Device business policy is another emerging trend that would not have been possible if not for cloud technology. This practice involves having employees bring their mobile devices to work, allowing them to access company files, data, and applications from their personally-owned gadgets in and out of the workplace.

As with any new business practice, the concept of BYOD can be both advantageous and disadvantageous. On the one hand, some believe it helps increase employee productivity and lifts their morale, while reducing overall IT costs. On the other hand, BYOD also opens up a whole new set of problems that are quite consistent with what many businesses take issue with with cloud technology: security. Do the pros outweigh the cons or vice versa? This much isn’t clear yet but what is evident is that more cloud apps are going mobile.

Efficiency, Innovation

While cost savings has always been one benefit that cloud proponents are quick to point out, its capability to improve and streamline business processes, thereby increasing efficiency and agility within the organization, is another key opportunity that the cloud offers. This is evident when you take a look at the most commonly used cloud services: backup and archiving, business continuity, collaboration tools, and big data processing.

Moreover, the cloud is making it easier for individuals to create new products and produce new lines of business. With access to higher IT capacity at lesser cost and at faster deployment rates, businesses can scale into more innovation without having to worry about the availability of computing resources.

Spend more to reduce costs?

It is becoming increasingly important to not to analyse energy consumption for all utility types, be it electricity, gas, water, heat, renewables, oil etc. The bottom line is both operational efficiency and utility costs monitoring. In the long run, these are management strategies designed to drive energy costs downwards as a continuous improvement cycle and as a measure of reducing carbon emissions.

It is also getting increasingly easier for organisations reduce energy use and achieve this goal using technology without having to “remember” to do it yourself. Organisations can never go wrong by investing in energy management software. There are varied software options to choose from depending on the organisational objective.
Some of the energy management objectives that organisations may need to meet are:

? Establishing baseline energy use

? Carrying out Energy audits

? Monitoring and measuring energy performance against the energy policies of an organisation and objectives

? Achieving energy certification
Energy management software?s come in handy when an organization wishes to achieve either of the above objectives.

Use of energy management software?s also assists organisations in measurement and verification of energy consumption as well as Monitoring and Targeting. Measurement and verification is where a company quantifies energy consumption beforehand (baseline energy use) and after energy consumption measurements are implemented in order to verify and report on the level of savings actually achieved.

Organisations that wish to verify the energy savings achieved by building retrofits can use energy management software?s. This is an important objective for companies that wish to either satisfy internal financial accounting and reporting requirements, or to meet the terms of third-party contracts for project implementation and management. Monitoring and targeting is also made easier by use of software. This is critical as a management technique, regardless of whether an organisation has specific facility retrofits in order to keep operations efficient and to monitor utility costs.
Overall, an investment in energy management software, is worthwhile in the achievement of management strategies designed to drive energy costs downwards as a continuous improvement cycle.
