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 Alcoa Canned the Cost of Recycling

Alcoa is one of the world?s largest aluminium smelting and casting multinationals, and involves itself in everything from tin cans, to jet engines to single-forged hulls for combat vehicles. Energy costs represent 26% of the company?s total refining costs, while electricity contributes 27% of primary production outlays. Its Barberton Ohio plant shaved 30% off both energy use and energy cost, after a capital outlay of just $21 million, which for it, is a drop in the bucket.

Aluminium smelting is so expensive that some critics describe the product as ?solid electricity?. In simple terms, the method used is electrolysis whereby current passes through the raw material in order to decompose it into its component chemicals. The cryolite electrolyte heats up to 1,000 degrees C (1,832 degrees F) and converts the aluminium ions into molten metal. This sinks to the bottom of the vat and is collected through a drain. Then they cast it into crude billets plugs, which when cooled can be re-smelted and turned into useful products.

The Alcoa Barberton factory manufactures cast aluminium wheels across approximately 50,000 square feet (4,645 square meters) of plant. It had been sending its scrap to a sister company 800 miles away; who processed it into aluminium billets – before sending them back for Barberton to turn into even more wheels. By building its own recycling plant 60 miles away that was 30% more efficient, the plant halved its energy costs: 50% of this was through process engineering, while the balance came from transportation.

The transport saving followed naturally. The recycling savings came from a state-of-the-art plant that slashed energy costs and reduced greenhouse gas emissions. Interestingly enough, processing recycled aluminium uses just 5% of energy needed to process virgin bauxite ore. Finally, aluminium wheels are 45% lighter than steel, resulting in an energy saving for Alcoa Barberton?s customers too.

The changes helped raise employee awareness of the need to innovate in smaller things too, like scheduling production to increase energy efficiency and making sure to gather every ounce of scrap. The strategic change created 30 new positions and helped secure 350 existing jobs.

The direction that Barberton took in terms of scrap metal recycling was as simple as it was effective. The decision process was equally straightforward. First, measure your energy consumption at each part of the process, then define the alternatives, forecast the benefits, confirm and implement. Of course, you also need to be able to visualise what becomes possible when you break with tradition.

Matrix Management: Benefits and Pitfalls

Matrix management brings together managers and employees from different departments to collaborate with each other towards the accomplishment of the organizational goals. As much as it is beneficial, matrix management also has limitations. Hence, companies should understand its benefits and pitfalls before implementing this management technique.

Benefits

The following are some of the advantages of matrix management:

Effective Communication of Information

Because of the hybrid nature of the matrix structure, it enables different departments to closely work together and communicate frequently in order to solve project issues. This leads to a proficient information exchange among leaders and subordinates. Consequently, it results to developed strategies, enhanced performance and quick productivity.

Efficient Use of Resources

Resources can be used efficiently in the organisation since it can be shared among functions and projects. As the communication line is more open, the valuable knowledge and highly skilled resources are easily distributed within the organisation.

Increased Motivation

The matrix structure promotes democracy. And with the employees working on a team, they are motivated to perform their duties better. The opinions and expertise of the employees are brought to the table and considered by the managers before they make decisions. This leads to employee satisfaction, empowerment and improved performance.

Flexibility

Since the employees communicate with each other more frequently, decision making becomes speedy and response is adaptive. They can easily adjust with diverse situations that the company encounters.

Skills Development

Matrix employees are pooled out for work assignments, even to projects that are not necessarily in line with their skill background. With this approach to management, employees have the chance to widen their skills and expertise.

Discipline Retention

One significant advantage of matrix management is that it enables the employees to maintain their skills in functional areas while working with multidisciplinary projects. Once the project is completed and the team wraps up, the members remain sharp in their discipline technically and return to their home functions.

Pitfalls

Here are some disadvantages of matrix management:

Power Struggle

In the matrix structure, there is always tension between the functional and project manager. Although their intent is polite, their conflicting demands and competition for control over the same resources make it more difficult.

Internal Complexity

Having more than one manager, the employees might become confused to who their immediate leader is. The dual authority can lead to internal complexity and possible communication problems. Worst, employee dissatisfaction and high employee turnover.

Heightened Conflict

In any given situation where people and resources are shared across projects, there would always be competition and conflict. When these issues are prolonged, conflicts will heightened and will lead to more internal problems.

Increased Stress

For the employees, being part of a matrix structure can be stressful. Their commitment is divided among the projects and their relationship with multiple managers requires various adjustments. Increased stress can negatively affect their performance in the long run.

Excessive Overhead Expenses

Overhead administrative costs, such as salaries, increase in a matrix structure. More expenses, more burden to the organisation. This is a challenge to matrix management that leaders should consider carefully.

These are just some of the advantages and disadvantages of matrix management. The list could go on, depending on the unique circumstances that organisations have. The key is that when you decide to implement matrix management, you should recognise how to take full advantage of its benefits and understand how to lessen, if not eradicate, the pitfalls of this approach to management.

Vendor Selection

When shopping for an IT solution for your enterprise, there are two things you should scrutinise: the product (or service) itself and its vendor. Many times, companies overlook the importance of the latter, giving the reason that “it’s only the product we need”.

Wrong.

What about after-sales technical support and training? Ok, so you have an in-house team with the required competency for that IT solution in question… not that I believe it’s reasonable basis to pass up on the expertise that the vendor can provide. How about upgrades, patches, and documentation?

Still unperturbed? Here’s one factor that you may not have started to consider – What happens to your product if the vendor goes bankrupt or gets swallowed by a merger and acquisition? Surely, you no longer believe this is far from possible, do you?

But how are you supposed to know the financial stability of each vendor or whether it is an acquisition target? Well, you can either conduct your own research or you can leave that up to us. Part of our job includes not only establishing linkages in the industry but also being in-the-know on such relevant information.

Evaluation of Business Needs

You can’t separate vendor selection from the process of choosing the desired IT tool. That’s why our vendor selection services starts by defining exactly what your business needs are.

Once we’ve pinned down your needs, we can then narrow down the list of possible IT solutions. Only then can we proceed with the main vendor selection process.

Have you ever been caught in a situation wherein you thought you knew what you wanted, only to end up realising it’s not what you were looking for after all? We’re here to make sure you don’t get caught in that kind of situation when choosing an enterprise-class IT solution.

With the TCO (total cost of ownership) of such solutions typically running up to hundreds of thousands of euros, you can’t afford to arrive at what you really want by way of trial and error.

These are the things you stand to benefit the moment we start working with you:

  • Thorough assessment of your IT needs. We’ll consult the people in your organisation who’ll be affected the most in order to obtain a clear picture of what your specific needs really are. Most IT solution purchases are made with very little consultation that, after installation, many of the end users don’t benefit at all.
  • Minimal interruption during assessment. As with all our other services, we see to it that the interruptions we make are absolutely necessary. So the moment we start with our work, you can still continue with yours.
  • Insightful suggestions of the required IT solution. You still know your business better. So even after we’ve gone through the assessment and given our recommendations, the decision as to what IT tool should be pursued will still be up to you. The difference now is, you’ll be making a decision based on expertly gathered information put forward in an insightful proposal.

Request and Evaluation of Vendor Proposals

With so many IT solutions companies mushrooming, it is becoming more difficult to keep track of them, their specialities, strengths, and weaknesses.

Companies selling best-of-breed products may be relatively easy to spot. But there are also other attributes that are equally important but not as well publicised. For instance, which companies offer better quality management philosophies? Which companies have strategic visions running parallel to yours? Which of them possess implementation capabilities that can cater to your rapidly growing IT requirements?

Vendors who answer positively to these queries need to be given the appropriate importance in the selection process. We see to it that these and other relevant attributes are factored into our scorecards and evaluation processes.

These are the things you can look forward to when you grant us the opportunity to serve you.

  • Experience is a vital item in our vendor selection criteria. Our vast knowledge of the reliable players in the industry will lead you to experienced vendors who can hit the ground running from day one and continue with the same vigour onward.
  • We can help you draw positive response for each of your Request For Proposals (RFPs) or Request For Information (RFIs). Did you expect these vendors to be enthusiastic in sending out proposals each time you asked them to? Think again. You’ll have to persuade them first of your sincerity to become a potential customer. With our help, your RFPs will make preferred vendors see “opportunity” written all over.
  • No need to go “Eany, meeny, miny, moe”. Deciding which vendors should move up in the selection process can take up a lot of time if you don’t know which criterion should be given more weight. Our scorecards are designed to collect the most relevant information and to generate results that will help you decide on these matters at a glance.

Interview, Negotiation, and Monitoring

As soon as you start getting positive response to your Request For Proposals, the interview process should be next. It’s at this point that vendors can present and highlight their strengths while we try to glean as much information of their true capabilities as well as their dedication to the project.

Some companies can provide proof-of-concepts and we may require them as part of the interview process. This will not only give us a better idea as with regards to their product’s capabilities, but also to their level of expertise on the solution in question.

  • We’ll help you set up the interview process and organise the evaluation committee. Members of the committee will typically include representatives from each department that will be affected by the new technology, which we would have already identified during our Evaluation of Business Needs.
  • Since our scorecards are designed to expedite the filtering and selection process, you may eventually be able to choose the finalists yourself. However, in the event that two or more vendors turn out evenly matched, we’ll help you identify the better company.
  • We’re very familiar with the price ranges of various IT solutions, including the effects on price of certain variables. As such, we can tell you whether a product’s price tag is justified or not.
  • Our exceptional familiarity on both the IT industry and the entire negotiation processes itself will give you the edge when it’s time for us to haggle for the best bang for the buck.
  • After the contract is awarded, we’ll even be on hand to monitor whether deliverables are handed over and milestones are achieved as promised.
