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.

How DevOps Could Change Your Business

Henry Ford turned the U.S. auto industry on its head when he introduced the idea of prefabricating components at remote sites, and then putting them together on a production line. Despite many industries following suit, software lagged behind until 2008, when Andrew Clay Shafer and Patrick Debois told the Agile Conference there was a better way to develop code:
– Write the Code
– Test the Code
– Use the Code
– Evaluate, Schedule for Next Review

The term ?DevOps? is short for Development and Operations. It first appeared in Belgium, where developers refined Shafer and Depois? ideas. Since then, DevOps became a counter movement against the belief that software development is a linear process and has largely overwhelmed it.

DevOps – A Better Way

DevOps emerged at an exciting time in the IT industry, with new technology benefiting from a faster internet. However, the 2008 world recession was also beginning to bite. Developers scampered to lower their human resource costs and get to market sooner.

The DevOps method enabled them to colloborate across organizational boundaries and work together to write, quality assure and performance test each piece of code produced in parallel.
DevOps? greater time-efficiency got them to market sooner and helped them steal a march on the competition.

There are many advantages to DevOps when we work in this collaborative way. Cooperation improves relationships between developers, quality assurers and end users. This helps ensure a better understanding of the other drivers and a more time-effective product.

Summary of DevOps Objectives

DevOps spans the entire delivery pipeline, and increases the frequency with which progress is reviewed, and updates are deployed. The benefits of this include:

? Faster time to market and implementation

? Lower failure rate of new releases

? Shortened lead time for bug fixes and updates

The Psycho-Social Implications of DevOps

DevOps drills through organization borders and traditional work roles. Participants must welcome change and take on board new skills. Its interdepartmental approach requires closer collaboration across structural boundaries and greater focus on overarching business goals.

Outsourcing the detail to freelancers on the Internet adds a further layer of opportunity. Cultures and time zones vary, requiring advanced project management skills. Although cloud-based project management software provides adequate tools, it needs an astute mind to build teams that are never going to meet.

The DevOps movement is thus primarily a culture changer, where parties to a project accept the good intentions of their collaborators, while perhaps tactfully proposing alternatives. There is more to accepting a culture than using a new tool. We have to blend different ways of thinking together. We conclude by discussing three different methods to achieve this.

Three Ways to Deploy DevOps in your?Organisation

If you foresee regular DevOps-based projects, consider running your entire organisation through an awareness program to redirect thinking. This will help non-participants understand why DevOps members may be ?off limits? when they are occupied with project work. Outsourcing tasks to contracting freelancers can mitigate this effect.

There are three implementation models associated with DevOps although these are not mutually exclusive.

? Use systems thinking. Adopt DevOps as company culture and apply it to every change regardless of whether the process is digital, or not

? Drive the process via increased understanding and feedback from key receivers. Allow this to auto-generate participative DevOps projects

? Adopt a continuous improvement culture. DevOps is not only for mega upgrades. Feedback between role players is paramount for success everywhere we go.

You can use the DevOps concept everywhere you go and whenever you need a bridge to better understanding of new ideas. We diminish DevOps when we restrict its usefulness to the vital role it plays in software development. The philosophy behind it belongs in every business.

Quality Assurance

 

There is a truism that goes “The bitterness of poor quality is remembered long after the sweetness of low price has faded from memory”.

While every consumer can probably relate to this idea, business enterprises offering goods and services are the ones that should heed this the most.

Quality Management Systems

The concept of quality was first introduced in the 1800’s. Goods were then still mass-produced, created by the same set of people, with a few individuals assigned to do some “tweaking” on the product to bring it to acceptable levels. Their idea of quality at that time may not have been that well-defined, but it marked the beginnings of product quality and customer satisfaction as we know it now.

Since then, quality has developed into a very basic business principle that every organisation should strive to achieve. Yet while every business recognises the importance of offering product and service quality, it is not something that can be achieved overnight.

If you’ve been in any type of business long enough, you should know that there is no “quick-fix” to achieving quality. Instead, it is an evolving process that needs to be continually worked on. And this is where the importance of having a workable Quality Management System (QMS) in an organisation comes in.

Whatever Quality tools and processes you need to implement the change needed in your organisation, we can help you with it. We are ready to work in partnership with your team to develop strategic systems which will produce significant performance improvements geared towards the achievement of quality.

What is a Quality Management System?

A Quality Management System is defined as the set of inter-related objectives, processes, and operating procedures that organisations use as a guide to help them implement quality policies and attain quality objectives.

Needless to say, the ultimate goal of every quality management system is to establish quality as a core value of the company among all employees, and across all products and services. Why? Because quality services make for happy customers, and satisfied customers ensure continued business for the company.

A Quality Management System does not stop with simply having a set of guidelines that the leaders of a company can easily have their organisation members accept and adhere to. Rather, effective QMS can be implemented when management provides a culture of pride and patience, which will inspire acceptance of individual and group responsibility.

In this manner, not only the heads of the organisation but the employees as well, will develop the desire to achieve company goals that will benefit:

  • All contributing teams;
  • The customers; and
  • The company as a whole.

What ISO 14001 Status did for Cummins Inc.

Cummins manufactures engines and power generation products, and has been a household name almost since inception in 1919. It sells its products in over 300 countries, through approximately 6,000 dealerships employing 40,000 people. Because its product line runs off fossil fuel it is under steady pressure to display a cleaner carbon footprint.

Cummins decided to go for the big one by qualifying for ISO 14001 certification. This is a subset of a family of standards relating to managing environmental impact while complying with all applicable legislation. In this sense, it is similar to the ISO 9000 quality management system, because it focuses on how products are produced (as opposed to how those products perform). Compliance with ISO 14001 was a doubly important goal, because it is part of the European Union?s Eco Management and Audit Scheme and fast becoming mandatory on suppliers to governments.

The qualification process follows the well-established principle of plan, do, check, act. It begins with gap analysis to detect materials and processes that affect the environment. This is followed by implementation of necessary changes affecting operations, documentation, emergency strategies and employee education. The third step involves measuring and monitoring performance. Finally, the project moves into a phase of ongoing maintenance, and continuous improvement as circumstances change.

In Cummins case, the project was almost worldwide and called for environmental, health and safety reporting throughout the organisation. The information was shared via a globally accessible document repository, and then processed centrally at the head office in Columbia, Indiana USA.

Measuring environmental performance almost inevitably has other benefits that make it doubly worthwhile. Speaking at the 2014 National Safety Council Congress after receiving the top award for excellence, Cummins chairman and ceo Tom Linebarger commented on a journey that was ?nothing short of amazing? yet wasn’t even a ?pathway to the finish line?.

?All of us feel like we have way more to do to make sure that our environment is as safe as it could be,? he added, ?so that our sustainability footprint is as good as it can be and that we continue to set more aggressive goals every year. That’s just how we think about it.? Linebarger concluded.

If you are taking your company on a journey to new heights of environmental excellence, then you should consider choosing ecoVaro as your travelling companion. We are environmental management specialists and have proprietary software geared to process your data. We also have a wealth of experience, and a treasure chest of roadmaps to help you achieve your goal.
