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.

Energy Savings Opportunity Scheme (ESOS): An Overview

Energy management is crucial to most businesses in the UK. This is primarily because energy usage substantially affects all organizations, whether large or small. The good news is that, energy costs can be controlled through improved energy efficiency. And this is exactly why Energy Savings Opportunity Scheme (ESOS) came into being ? to promote competitiveness among businesses.

Energy Savings Opportunity Scheme is the realisation of the UK Government’s ambition towards achieving the maximum potential of cost-effective energy in the economy. ESOS aims to stimulate innovation and growth, cut emissions and support a sustainable energy system.

ESOS at a Glance – Legal Perspective

The EU Energy Efficiency Directive took a major step forward on November 14, 2012 and headed towards establishing a framework to promote energy efficiency across various economic sectors. To interpret Article 8 of the Directive, the government has given birth to ESOS; requiring large enterprises to undergo mandatory energy audits and energy management systems by December 5, 2015 and at least every 4 years thereafter.

Large enterprises include UK companies that have more than 250 employees or those businesses whose annual turnover exceeds ?50 million and whose statement of financial position totals more than ?43 million. With this, over 7000 of the biggest companies in Britain will need to comply with ESOS as an approach to review their total energy use in buildings, business operations, transport and industrial processes.

Generally, ESOS is both an obligation and an opportunity. It is an obligation for the indicated target companies since they need to submit to additional regimes; focus on audit evidences; act in accordance to group structures and compliance; and observe limited penalties and note retention periods. Moreover, it is also an opportunity for companies to strive for more savings on energy projects; attempt to standardise their potential market; and effectively lower debt and legal costs.

ESOS Audits ? Looking Beyond

According to the Department of Energy and Climate Change (DECC), average first audit costs would be estimated at about ?17,000 and subsequent ones at around ?10,000. As expected, these audits will result in energy saving recommendations, of which companies need not proceed for a follow up; and substantially improve businesses in their energy management issues. DECC further states that every business that complies with ESOS could save an average of ?56,400 each year from an initial investment of ?17,000 only.

Currently, up to 6,000 UK businesses are already subject to existing CRC Carbon Reduction Scheme, Mandatory Carbon Reporting, Climate Change Levy and other compliance. This signifies that ESOS may overlap with prevailing energy efficiency legislation and may put additional pressure on energy administration. While this is true, however, ESOS holds extensive benefits. Although the scheme can be viewed as another costly compliance to environmental standards, ESOS goes straight to the bottom line and provides the organisation with competitive advantage. If large businesses act now and comply with it, they will be able to enjoy maximised payback in the long run.

Indeed, Energy Savings Opportunity Scheme is already here. It is mandatory with minimal investment. And all you have to do is act quickly, implement new improvements and earn more.

Mobile Security

Today’s advanced enterprises make extensive use of mobile devices in order for team members to exchange information, collaborate, and carry out business whenever and wherever they need to. BlackBerries, iPhones, Google Phones, and other smartphones as well as PocketPCs and PDAs are now allowed wireless remote access to the enterprise network.

As a result, they introduce additional vulnerabilities into the system.

  • Bluetooth exploits and unencrypted passwords can allow malicious individuals to gain access to private information.
  • Various wireless technologies that have substantially simplified the task of transferring data have provided openings for malicious code. In addition, the diversity of these wireless technologies combined with the constrained environments of these devices have made it difficult to come up with an all-in-one solution.
  • All PocketPCs, PDAs and smartphones can be synchronised with PCs and laptops, giving malware an entry point into computers and networks. Memory cards are guilty of this too.
  • VoIP, which are usually unencrypted, allow other people to perform unauthorised capture and recording of private conversations.

Mobile security is still an emerging discipline. Because of this, many organisations that allow members’ mobile phone access into the network don’t actually have a specific security policy for such devices.

That’s why we’re here to help. We’ll conduct a thorough evaluation of your security policies and systems in relation to mobile devices and seal gaps we spot along the way. If you don’t have the needed policies or if what you have needs an overhaul, we’ll set everything up (including the needed applications and infrastructure) for you.

Once we’ve got everything in place, you won’t have to worry about the vulnerabilities mentioned earlier. In addition to that, your organisation will already be capable of preventing the following:

  • Access to company information when the phone ends up in the hands of anyone other than the authorised user.
  • Being billed for phone usage due to virus activity
  • Unauthorised phone activity monitoring through spyware
  • Other disruptions caused by mobile-based malware

Other defences we’re capable of putting up include:

Systems Integration as a means to cost reduction

System integration in an organisation refers to a process whereby two or more separate systems are brought together for the purpose of pooling the value in the separate systems into one main system. A key component of process consolidation within any organisation is the utilisation of IT as a means to achieve this end. As such, system integration as a means to cost reduction offers organisations the opportunity to adopt and implement lean principles with the attendant benefits. The implementation of lean techniques requires an adherence to stated methods to facilitate the elimination of wastage in the production of goods and services. In summary, the lean philosophy seeks to optimise the speed of good and service production, through the elimination of waste.

While analysing some of the traditional sources of waste in organisational activities, things like overproduction, inventory, underutilised ideas, transmission of information and ideas, transportation of people and material, time wastage and over-processing stand out. The fact is that companies can eliminate a significant portion of waste through the utilisation of IT to consolidate processes within their organisation.

Adopting lean principles calls for the identification of all of the steps in the company value stream for each product family for the purpose of the eliminating the steps that do not create any value. In other words, this step calls for the elimination of redundant steps in the process flow. This is exactly what the utilisation of IT to consolidate processes offers a company. For instance, the adoption of a central cloud system across a large organisation with several facilities could increase efficiencies in that company. Such a company would drastically reduce the redundancies that used to exist in the different facilities, eliminate the instances of hardware and software purchase, maintenance and upgrade, modernise quality assurances processes and identify further opportunities for improvement.

Perhaps, from the company’s point of view, and from the perspective of lean process implementation, the most important factor is?the effect it has?on the bottom line.’reducing the number of hardware, eliminating the need for maintaining and upgrading hardware, removing the necessity for software purchase and upgrade across facilities also contributes to a significant reduction in operational costs.?This reduction in the cost of operations leads to a corresponding increase in the profit margin of the company.

Applying system integration as a means to cost reduction can also lead to the reduction in the number of people needed to operate the previous systems that have been integrated into one primary unit. Usually, companies must hire people with specialised knowledge to operate and maintain the various systems. Such employees must also receive special training and frequent ongoing education to constantly stay informed of the latest trends in process management. With the integration of the system, the number of people needed to maintain the central system will be significantly reduced, also improving the security of information and other company trade secrets.

Based on an analysis of the specific needs that exist in a particular company environment, a system integration method that is peculiar to the needs of that organisation will be worked out. Some companies may find it more cost-effective to use the services of independent cloud service providers. Others with more resources and facilities may decide to set up their own cloud service systems. Often, private cloud service system capabilities far exceed the requirements of the initiating company, meaning that they could decide to “sell” the extra “space” on their cloud network to other interested parties.

A company that fully applies the lean principles towards the integration of its systems will be able to take on additional tasks as a result of the system consolidation. This leads to an increase in performance, and more efficiency due to the seamless syncing of information in a timely and uniform manner.

Companies have to combine a top-down and a bottom-up approach towards their system integration methods. A top-down approach simply utilises the overall system structure that is already in place as a starting point, or as a foundation. The bottom-up approach seeks to design new systems for integration into the system. Other methods of system integration include the vertical, star and horizontal integration methods. In the horizontal method, a specified subsystem is used as an interface for communication between other subsystems. For the star system integration method, the subsystems are connected to the system in a manner that resembles the depiction of a star; hence, the name. Vertical integration refers to the method of the integration of subsystems based on an analysis of their functionality.

The key to successful system integration for the purpose of cost reduction is to take a manual approach towards identifying the various applicable lean principles, with respect to the system integration process. For instance, when value has been specified, it becomes easier to identify value streams. The other process of removing unnecessary or redundant steps will be easier to follow when the whole project is viewed from the whole, rather than’the part. Creating an integrated system needs some?patience?in order to work out kinks and achieve the desired perfect value that creates no waste.
